RECEIVE ORFIELD NOISE MONITORING ANALYSIS ACTION TO BE To accept the noise monitoring analysis report and request a review and recommendation by the Airport Relations Commission. FACTS: ■ Elliott Dick, Orfield Laboratories, will present and discuss the results from the phase I - phase II noise comparison study. ■ Wyle Laboratories conducted the initial noise study in June 2005, prior to the new north - south Runway 17/35 opening. ■ The city hired Orfield Laboratories to perform the follow up noise study, post -runway opening. That study was completed in June 2006. ■ The raw data collected during the phase II study showed little, if any, change from data • collected during the pre -runway study. Orfield was hired to compare and analyze "results from Phase I and Phase II studies.

Update on Preplanning Efforts to Ensure Continuity of Government Operations in the Event of an Pandemic ACTION TO BE CONSIDERED: No Formal Action Required FACTS: • At a May 2006, listening session, the Eagan City Council received a briefing about the need for city staff to begin developing a continuity plan in the event of an Avian Influenza Pandemic. • A committee of city staff members has been meeting regularly and is in the process for developing a plan for future council consideration. • • It is anticipated the council would be able to review the plan in December, 2006. ATTACHMENTS: :Memo from James McDonald, Chief of Police, to the Mayor and Council regarding Avian Influenza planning efforts. Attachments on pages through • a CitOl �n nn POLICE DEPARTMENT a�Ian MEMORANDUM DATE: October 5, 2006 TO: Eagan Mayor and City Council Members FROM: James S. McDonald, Police Chief SUBJECT: Planning Update in the event of an Avian Influenza Pandemic Purpose At a May 2006, Eagan City Council Listening Session, the Mayor and Council received a briefing outlining the need for staff to begin planning a city response to a potential Avian Influenza Pandemic. This document will attempt to update the mayor and council on planning initiatives. • Brief History and Current Status of Avian Influenza As described previously, Avian Influenza (flu) is a virus that is highly contagious and mainly effects birds. The current Avian Flu, identified as H5N I, has been found in Africa Asia, and Europe where it has caused the death or destruction of an estimated 150 million birds. The virus is generally "species specific," but has crossed the "species barrier" and infected humans. Although there are an extraordinary high number of casualties in birds, there have been a low number of human deaths related to the virus. Statistics compiledearlier this year note there were approximately 148 human deaths reported world wide. The humans who died from the H5N 1 virus had lived in the undeveloped countries of Asia where farmers lived/worked in close proximity to poultry who had the disease. Although, it is difficult for humans to get the H5N 1 virus directly from birds, it is believed humans inhabiting an environment where they butcher infected fowl or come in contact with bird feces are at a higher risk of contracting the disease. Transmission of the H5N1 virus from human to human is very unlikely. However, if the virus were to mutate, or "re -assort" with another virus that is readily transmitted between humans, a stage will be set for a worldwide pandemic. It should be noted, health officials are studying a case in Indonesia where a human to human transfer among family • members may have occurred. 3 Assumptions in the Event of an Pandemic Page 2) • According to information from the Minnesota Department of Public Safety, the following planning assumptions should be considered by local units of government in their continuity of government planning. A. A pandemic could last 6-8 weeks and include several waves over the course of a year. B. Up to 30 percent of the workforce could be out sick during a pandemic. Absenteeism could reach 40 percent during the peak of a pandemic. People may decide to stay home to care for family members or for children when schools are closed. Fear of exposure may lead to lower rates of absenteeism before an actual outbreak begins. C. Employer flexibility will be necessary and might include staggered shifts, expansion of physical space between work stations, or allowing employees to work from home. D. Leave policies may need to be flexible. E. Employees may need personal protective equipment (PPE) to maintain priority • service functions. This requires implementation of PPE policies and procedures and ensuring the required training and fit testing is done. F. Availability of supplies will be limited because of hoarding, combined with limited production and transportation limits: G. Administrative rule waivers and alternate service delivery systems may be necessary to maintain priority service functions. Local jurisdictions should develop policies for reduced service delivery. H. Community buildings may need to be used as alternate care facilities and standards of care may need to be adjusted when hospitals are overwhelmed. Local jurisdictions need to make sure they can staff existing health care facilities before establishing alternate health care facilities. (Ensure that these alternate sites can be staffed locally prior to opening. Make sure that the facility owners/operators know they are in the local plan.) I. Up to two percent of the 30 percent who fall ill may die. This rate could overwhelm mortuary and burial services. Local jurisdictions may need to assist local mortuary services. J. Assistance from outside organizations, county, state and federal government will • be limited. • Page 3) Current Status of City Efforts Since May, 2006, employees from police, fire, community development, human resources, public works, parks, information technologies, communications, and emergency management have been working to develop a plan that would help the city manage a pandemic scenario. While using the above assumptions along with trying to forecast the potential impacts on city employees and community members, the committee has been reviewing operations and evaluating the potential implications on service delivery in the event our workforce is impacted by a pandemic. Ultimately, the evaluations will be placed into a pandemic plan that will be reviewed by senior management. After the review, the document will be forwarded to the city council for consideration. It is anticipated the plan will be forwarded to the council for approval in December, 2006. Conclusion Although the committee is carefully evaluating service issues that may need to be managed in the event of a pandemic, it is important to realize the difficulty of developing • steadfast plans when you have to rely upon a workforce that may not be available. Consequently, any plan developed will need to have some inherent flexibility to reassess any unforeseen issues that may arise. • Thank you for your consideration in this matter.

REVIEW PROPOSED BURNSVILLE/EAGAN COMMUNITY TELEVISION (BECT) 2007 OPERATING BUDGET DIRECTION TO BE • To provide direction, if any, to staff regarding the 2007 Burnsville/Eagan Community Television Budget and to direct that it be placed on a future regular City Council meeting consent agenda for formal ratification. . BACKGROUND: • Community Television operates under a joint powers agreement with the cities of Ir. Eagan and Burnsville. • Equal contributions of $103,500 each by the member cities remain the same. • With the exception of a 3% cost of living adjustment and an increase in hours for part-time cablecasters (to facilitate Web streaming), the operating budget is essentially unchanged from 2006. • Capital expenditures in 2007 are up significantly, reflecting underspending on replacement in 2005 and early 2006, and the anticipated need to replace studio equipment in. 2007. Capital spending was originally budgeted and approved at more than $136,000 for 2006, but by year's end staff estimates spending will only • amount to $76,000. That additional $60,000 will be carried forward into 2007. • Note that should BECT later relocate to a different facility, studio systems and cameras can also be relocated. Without upgrades in 2007, BECT would likely be left without a functioning facility. • Per direction of the two city councils, the city attorneys of Burnsville and Eagan are in the process of wrapping up a 1 -year lease at the current facility to preserve maximum flexibility bothin teams of national franchise legislation and/or expanded partnerships in Dakota County. • The 2007 budget is modeled on normal operations. Should new federal legislation pass, staff will return to both city councils with any necessary budget revisions or reconsideration. • Even without changes by Congress, as noted on the attached chart, a plan to fund capital improvements beyond mid -2010 is necessary. While this is actually an improvement on earlier 2004 fund balance projections, much more work remains to be done. • Long-term funding, location and facility -size discussions will be a major focus of the 2007 work plan, along with generating additional outside revenue for the facility. • It may also be of interest for the City Council to note that the Telecommunications Commission received the findings of a Subscriber Survey from'Dr. Bill Morris of Decision Resources. The survey was commissioned to determine satisfaction with services offered by Comcast, viewership, and value • perception for community television programming. 400 subscribers were surveyed in March/April of 2006. • Overall customer service ratings for Comcast were positive with 80% giving a "good" or "excellent" rating. Only 6% said customer service was "poor" Ir. • As for local programming, 83% said it was important or somewhat important to • have available. • City Council meetings are the most highly viewed public meetings with 7% saying they watch frequently and 48% watching occasionally. • The survey presentation is available on cable television Channel 16.

STATUS REPORT - 2008 COMPREHENSIVE PLAN UPDATE DIRECTION TO BE CONSIDERED: To review/comment and/or provide staff with direction regarding the Plan Update. FACTS: Earlier this year, the City Council directed staff to begin the process of updating the Comprehensive Plan. A fall check point, with the Council, was built into that process. ➢ In Minnesota, authority for land -use planning and regulation is vested primarily in local governments. The Metropolitan Land Planning Act, a state law first passed in 1976 and amended several time since, requires local governments in the seven -county Twin Cities area to develop local comprehensive plans. ➢ The plans must contain a number of elements, among them: • o Maps and data showing current and future land use o A Housing plan o A surface water management plan o Plans for public facilities, like transportation, sewers, and parks is ➢ The Metropolitan Land Planning Act requires communities to review and update their local comprehensive plans at least once every 10 years. Local plan updates are due in 2008. ➢ Communities then submit their plans to the Metropolitan Council, which determines if the local plans: o Conform to metropolitan system plans o Are consistent with other adopted plans of the Metropolitan Council o Are compatible with each other ➢ Local governments may not implement any measures that would allow development in conflict with the Comprehensive Plan reviewed by the Metropolitan Council. ➢ Additional Council check points and opportunities for public input will occur throughout 2007. Staff would propose that the next checkpoint occur in the spring of 2007 and that a schedule be established at that point for the remainder of the review and public input process. 10 ➢ The background attachments are presented in an executive summary form. As with the • budget presentation in August, staff have a limited formal presentation and will step through the section summaries to permit the Council to review and comment on the sections as appropriate. ATTACHMENTS: (1) Executive summary/status reports, by Comprehensive Plan.section, are attached on pages through. • r� U Comprehensive Guide Plan 2008 Update • Executive Summary Plan Section — LAND USE Purpose of Section in the Comprehensive Plan The purpose of the Land Use Section of the Comprehensive Guide Plan is to define the City's vision and expectations for land use throughout the City. The 1995 Amendments to the Metropolitan Land Planning Act require that local governments achieve consistency between their Comprehensive Plan and Zoning Ordinance. While the Comprehensive Plan describes the vision for how Eagan should develop over the next 10-20 years, the Zoning Ordinance is the tool for achieving that vision by specifically regulating the type, scale and location of development. Certainly the overall character of the City has changed over the past twenty years from a mostly developing community to a developed community. To date approximately 96% of the land in Eagan has been developed. Therefore, significant changes in development patterns are not anticipated in the 2008 Land Use Plan. However, changes will continue to occur in response to new trends and as older uses redevelop to new uses. Status of Work to Date The Land Use Section of the current Comprehensive Plan Land Use Section has been generally • reviewed by the Advisory Planning Commission in a Workshop setting and planning staff will complete an inventory that will define existing inconsistencies and highlight current vacant and underutilized land for discussion in the coming months. • Additionally, every residential property will be viewed in 2007 via a windshield survey that will confirm the general site conditions and use. Examples of Emerging Issues and Trends • An aging population (as the Baby Boomer generation works through its life cycle) will have an impact of some kind on Land Use from residential, fewer persons available to purchase boomer housing, to commercial/industrial, fewer persons entering the work force. • As commercial industrial build out occurs and existing facilities age, the need to reuse, revitalize or redevelop certain properties will become increasingly important to meet demand for business growth and/or reallocation within the community. • Eagan has benefited by diversity in its business community and has been buffered from economic cycles for that reason. The City will benefit by continuing to position itself to support commercial/industrial diversity in the future. • Changes in businesses and their products are leading to the increasing presence of a variety of home based businesses and possible interest in live -work land use altematives. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. )a Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — TRANSPORTATION PLAN .Purpose of Section in the Comprehensive Plan The purpose of the Transportation Element of the Comprehensive Guide Plan is to: 1) identify existing and future transportation needs in terms of the roadway and non -roadway system; 2) influence decisions that the City is making by anticipating the character, magnitude, and timing of future transportation demand; and 3) provide for an integrated transportation system that will serve the needs of its residents, support the City's development plans, and complement the metropolitan transportation system that lies within its boundaries. In addition to guiding development of the City's transportation system, the plan fulfills the requirements of Minnesota Statutes Section 473.859 (subdivision 3) requiring a public facilities plan section within a comprehensive plan to be submitted for Metropolitan Council approval. Status of Work to Date Is Separate Comprehensive Transportation Plans have been prepared and/or updated previously to meet the Metropolitan Council's Comprehensive Guide Plan requirements. In 2006, the consulting firm of SRF Consulting Group, Inc. was again retained to prepare this next update. To date, the process is approximately 20% complete and a final draft will be ready for formal review • by February 20, 2007. Copies will be sent to adjacent communities and regional agencies for review and comment during the second quarter of 2007. There are no public reviews planned beyond those associated with the overall Comprehensive Guide Plan review. Complementary efforts that have been under taken since the previous plan update and that are currently underway including the following: • City of Eagan Transportation Infrastructure Needs Analysis (TINA) • CSAH 28 (Yankee Doodle Road) Corridor Study • Eagan/Inver Grove Heights North-South Corridor Study Examples of Emerging Issues and Trends Continued population and employment growth in the City, as well as surrounding communities, will result in increasing demand to the transportation system. Greater local and regional funding for transportation and transit improvements will need to be pursued to provide for adequate preservation and expansion of the transportation system. The community's growing desire for choice in transportation, including walkability within the City and improved transit service, will require coordinated and complimentary land use and transportation planning. Future transit opportunities include expanded transit service, Cedar Avenue BRT and Robert Street Corridor Transitway. Identification of transportation problems and opportunities in terms of roadway capacity, safety, functional classification, and jurisdiction may likely lead to changes requiring • 13 other agency approval or agreements. Some changes may provide additional financial burden to the City, while the lack of approval may limit funding opportunities. • The development of a Neighborhood Traffic Management Plan/Policy is very likely to address requests for reduced speed limits, stop signs, traffic calming, etc. • Creation of a "transportation impact fee" for all future development or redevelopment to address increasing transportation system demand and decreasing funding opportunities. • Increased emphasis on securing funding sources to complete the design and construction of the Ring Road. • Use of roundabouts versus traffic control signals. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — AVIATION/AIRPORTS Purpose of Section in the Comprehensive Plan The purpose of the Aviation/Airports Section of the Comprehensive Guide Plan is to define the City's relationship with the Minneapolis -St. Paul International Airport in the context of both its environmental impacts on the residential community and its benefits as an amenity for both the residents and businesses in the community, because of its proximity to the City. Status of Work to Date With its update of the Metropolitan Systems Plans in preparation for the cities' Comprehensive Plan updates, the Metropolitan Council incorporated its Aviation Plan into the Region's Transportation Plan. To conform with that approach, staff proposes to incorporate the City's Aviation/Airports Section into the Comprehensive Plan Transportation Section. Aviation will continue to be a defined subsection of the Transportation Section and the update has been initiated with that expectation. In 2006, the Airport Relations Commission and City staff have begun work on several activities that relate to the update of this Plan Section. Aviation/Airports Section Update — Dianne Miller — Staff and the Commission have • prepared a draft update and performed a preliminary review of issues and topics to be addressed. That work will continue in the months ahead. It is anticipated that the ARC. will hold its own public input meetings prior to incorporation of the draft into the formal plan for the APC's public review. North-South Runway Noise Monitoring Study — Orfield Labs — The City's pre and post opening noise studies have been completed and the results will be used to further define goals and policies relative to the new runway and its operation. Examples of Emerging Issues and Trends • The FAA's use of the North-South Runway continues to evolve. To date, it has resulted in operations different from what had been anticipated during the planning and environmental review processes. • The economic health of the airline industry will have direct, but opposite, impacts on Eagan's economic amenities and noise environment. • Continued conversion of hush-kitted aircraft to factory stage III aircraft will have a generally positive influence on single event noise levels. • The trend away from regional propeller planes and toward smaller regionaf jets may counterbalance some of that effect. • Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (SANITARY SEWER) Purpose of Section in the Comprehensive Plan The purpose of the Sanitary Sewer Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) project municipal demand on Metropolitan Council's interceptors and wastewater treatment plants; 2) specify areas to be served by the public sewer system 3) outline a program for addressing inflow and infiltration into the sewer system; and 4) set standards for private sewer systems, as applicable. The City is preparing the Sanitary Sewer Plan as a two step effort. Since the Metropolitan Council will not review a 2030 Sanitary Sewer Plan prior to receiving a 2030 Land Use Plan, the first step is to submit an Amendment to the already approved Sanitary Sewer Plan (originally submitted in 2000). In many aspects this Amendment will be identical to what will become the 2030 Sanitary Sewer Plan. Submitting the document as a 2020 Amendment allows Metropolitan Council to review the document and offer official comment's. These comments will assist the City in quickly turning this document into a 2030 Sanitary Sewer Plan that supports the over Comprehensive Guide Plan submittal. • Status of Work to Date Separate local Comprehensive Sanitary Sewer Plans have been prepared and/or updated in 1965, 1976, 1982, 1988, and 2000 in concert with the City's significant growth. In 2006, the consulting firm of Bonestroo, Rosene, Anderlik & Assoc was again retained to prepare both the Amendment to the current 2000 Plan and the ultimate 2030 Update. The Amendment is approximately 95% completed and will be submitted for staff review in mid October. A final draft will be ready for formal review by Metropolitan Council in late October or early November, 2006. Copies will be sent to adjacent communities for review and comment concurrent with the Metropolitan Council review. There are no public reviews scheduled beyond those associated with 'the overall Comprehehsive Guide Plan review. Examples of Emerging Issues and Trends • In the 2000 Sanitary Sewer Plan there was a large discrepancy between the City's projected flows and those of Metropolitan Council. The discrepancy was due to the City's flow projections for commercial land being reasonably conservative but not reflective of the actual flows generated by typical commercial properties in the City. In order to preempt dispute on sewage flows, the current Sanitary Sewer Plan projects flows using two methods. The first reflects "current trends" and uses lower flows from commercial properties based on historical flows records. These "current trends" flow estimates will be reported to Metropolitan Council and more closely match the Council's own predictions. The second method is "system design" and reflects the higher design flow for commercial property, similar to the 2000 Sanitary Sewer Plan. The "system • design" flows provide a trunk system that allows the City a certain measure of reserve capacity in the event that a high sewage generating use does appear within its borders. AV • In 2005, the Metropolitan Council instituted an Inflow/Infiltration (I & I) Surcharge • Program to eliminate the additional capacity within its interceptor system needed to serve excessive I & I. The Met Council established I & I thresholds, and communities that exceed this threshold are required to eliminate this excess flow within a reasonable timeframe. The 2030 Sanitary Sewer Plan Update will address the City's plan for reducing I & I below the established threshold. • Flow from the Minnesota Zoo in Apple Valley into Eagan's system accounts for the majority of the current documented excessive I & I. The 2030 Plan will better define the City and Zoo's responsibility toward this excessive I & I and the related financial surcharge. • The current Sanitary Sewer Plan and its flow projections include redevelopment and build -out of certain underutilized parcels within the City. These specific modifications to the land use plan will also include the Cedar Grove Redevelopment area. • Although not yet formally considered by the Eagan Council, the City of Rosemount's previously expressed interest in extending sanitary sewer service south of 1200' Street along the TH 3 corridor has been taken into consideration in calculating ultimate flows to properly evaluate the maximum impact on the entire system. • Other — The Council may identify other trends. and issues to be.addressed in the course of the Comprehensive Plan update process. F_ -I LJ 11 17 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (STORM SEWER) Purpose of Section in the Comprehensive Plan The purpose of the Storm Sewer Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) manage stormwater volume and rate control for flood. protection; 2) develop, operate, and maintain the public storm drainage system; 3) minimize erosion and sedimentation and 4) promote groundwater recharge. Status of Work to Date Separate local Stormwater Management Plans were prepared or updated in 1965, 1972, 1978, 1984, and 1990 in concert with the City's significant growth. In 1999, the consulting turn of Bonestroo, Rosene, Anderlik & Assoc. was again retained to update the 1990 plan. Near the proposed completion of the plan, the City was flooded in multiple areas as a result of the July 2000 Super Storm. All efforts on the plan were redirected toward the analysis and mitigation of the Super Storm. As a result of the flooding associated with the Super Storm, the scope of the plan update was modified to incorporate the analysis of the entire City to the level of a storm • event comparable to the July 2000 Super Storm. The plan was also revised to provide a more operational perspective on flood control at significant ponds within the storm sewer system. The update of the Stormwatei Management Plan was completed and formally approved by the City Council on January 17, 2006. Copies will be sent to adjacent communities for review and comment concurrent with the Metropolitan Council review. No public reviews have been scheduled, although the opportunity exists with the overall Comprehensive Guide Plan review. Examples of Emerging Issues and Trends • The comprehensive Stormwater Management Plan identifies a concept of providing for the managed conveyance of storm water flows from southeast Eagan into and through, as well as for, the Lebanon Hills Regional Park (LHRP). The proposed concept addresses past flooding of private property within the City and a County highway (Cliff Road). LHRP consists of approximately 1,400 acres, but does not have a managed surface water drainage system in place, although they have recently prepared a draft comprehensive drainage plan to manage the rate and volume of water that enters and flows through the park. On July 6, 2004, the City Council approved a project for constructing new storm sewer from southeast Eagan (Gun Club pond) into and through LHRP by way of Marsh Lake and McDonough Lake to the public system at Pond LP -51 and the Holland Lake lift station. City staff has communicated extensively with the staffs of Dakota County Parks and the Minnesota Department of Natural Resources. In order to construct the proposed improvements, approval will be needed from both of these agencies, as well as permission from the Met Council to work within LHRP. In the past, Dakota County has expressed objections to the amount of their proposed financial participation. However, a • sunset date of June 2007 for designated state funding ($500,000) for the improvements may encourage approval from the County. /Y • Compliance with evolving federal and state stormwater requirements (i.e. stormwater • pollution prevention, non -degradation and Impaired Waters/TNIDLs) will likely require additional staffing needs or consultant services. •' Development of policies/regulations for new development and re -development regarding Low Impact Development (LID) (i.e. impervious surfaces, infiltration, best management practices) may be required. • Long term maintenance of ponding areas for dry & wet stormwater storage volumes and the associated access to these drainage ponds will likely need to be addressed in order to maintain compliance with new requirements. • The lack of drainage and utility easements around some lakes, ponds and wetlands included as part of the public storm sewer system may incur significant acquisition costs. • Provisions for storm sewer design and the associated easements for a "July 2000 Super Storm" event are continuing to be requested by the public. Does the City raise the "standard" storm sewer design? • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • i9 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (WATER SUPPLY & DISTRIBUTION) Purpose of Section in the Comprehensive Plan The purpose of the Water Supply and Distribution Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) project the future use and peak demand requirements of the community; 2) evaluate the quality, availability and dependability of supply resources; and 3) plan for the City's ability to treat, store and distribute potable water to all users in compliance with the Minnesota Department of Health standards. Status of Work to Date Separate Comprehensive Water Supply & Distribution Plans have been prepared and/or updated in 1965, 1969, 1976, 1982, 1988 and 1996 in concert with the City's significant growth. In 2006, the consulting firm of Bonestroo, Rosene, Anderlik & Assoc was again retained to prepare this next update meeting the Metropolitan Council's Comprehensive Guide Plan requirements as well. The update is approximately 95% completed and a final draft will be ready for formal review by October 31, 2006. Copies will be. sent to adjacent communities and regional agencies for review and comment during the first part of 2007. There are no public reviews planned beyond those associated with the overall Comprehensive Guide Plan review. • Examples of Emerging Issues and Trends While the metropolitan area is blessed with an abundant aquifer for potable drinking water supplies, it is limited. Ground water protection, conservation measures and alternative sources need to be evaluated to insure a reliable source for the City's future projected needs. The emergency and conservation sections of this plan will address various options and policies to encourage, or enforce as necessary, conservation measures to meet Metropolitan goals. The emergency plan outlines safety and security measures, and identifies potential interconnections with neighboring communities. Approximately five more wells are required to serve full build out of the city. General site locations have been identified for these wells based on previous ground water geologic studies. Future wells will be developed as demand occurs. However, design, construction and permitting of a new well facility takes approximately two years to complete. Therefore, it is important to continually re-evaluate the Capital Improvement Plan in light of the latest development and re -development plans. Several minor improvements are required at the Cliff Road Water Treatment Facility to improve operation of the facility and provide treated water to the expansion of the southeastern portion of the City. The needs of the Sperry Water Tower are marginal for future water supply and/or pressure requirements. An economic analysis should determine if it is cost effective to keep it as part of the water system or if it should be replaced with a more conventional low maintenance antenna tower for public safety and commercial uses. N Additional water storage may be required to adequately serve redevelopment of the is northeast area of the city. Previous Water Supply and Distribution Plans have proposed building a second ground storage reservoir adjacent to the existing Yankee Doodle Reservoir, on existing City property. This study has determined that an alternative site in the northeast redevelopment area provides a slight operational benefit over the original alternative of the second Yankee Doodle Reservoir. However, due to lower ground elevations in the northeast area, the reservoir would likely have to be constructed as an elevated water tower. Also, a site would have to be purchased for the northeast water tower. As the northeast area redevelops, further study is warranted to: first, determine the need for additional storage, and second, determine the costs and benefits of an elevated tank in the northeast area as compared to a ground storage tank at the current Yankee Doodle site. Several minor piping modifications and pressure zones realignments are required to increase fire flows and pressures,to serve the planned redevelopment of the Cedar Grove commercial area. Additional trunk water mains are required to serve development. These pipes are normally installed as each area develops. The largest project involves construction of a trunk water main on Cliff Road, from Lexington to Dodd Road. The purpose of this pipe is to supply the continued development of the southeastern part of the City (including the portion of Inver Grove Heights that is served by Eagan water), as well as to provide critical redundancy and looping of the portion of the system. The Safari Pass, Fairway Hills and portions of the Park Cliff neighborhoods experience low water pressures because of higher ground elevations. Many homes in these areas have installed individual booster pumps to improve pressure. In-home booster pumps are • high maintenance with a limited life and the Minnesota Department of Health discourages their use. This study has identified several alternatives to increase system pressures in these areas. Further economic analysis will determine if it is cost effective for the City to construct system facilities that would allow the in-home booster pumps to be disconnected. Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • th • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PARKS & RECREATION Purpose of Section in the Comprehensive Plan The purpose of the Parks and Recreation Section of the Comprehensive Guide Plan is to outline a strategy for provision of recreation spaces, facilities and programs so as to encourage positive resident interaction, provide a sense of community and support economic development of the community. Status of Work to Date The 20/20 Vision, completed in early 2006, provides much of the information needed to update this section. A subcommittee of the Parks Commission has been established to review and incorporate applicable information from the 20/20 Vision into the Comprehensive Guide Plan update. Staff is working to update individual park plans presented in the 1994 Park System Plan to reflect work done to date. The Patrick Eagan Park Master Plan, currently underway, will provide a set of criteria and scoring mechanism for determining the value of potential land acquisitions. The Parks Commission has also been advised by the City Council to continue researching and discussing • potential sources of funds for future land acquisitions and park improvements. Examples of Emerging Issues and Trends 0 • New sources of funding for land acquisitions and park improvements will need to be secured as payments to the Park Site Fund diminish. • The City will need to weigh the value of the land as open or park space in relation to other potential uses as undeveloped land continues to become scarce in Eagan. • Programs and facility uses may need to shift in order to meet the changing demographics and social trends in the community. • Written partnership agreements with community user organizations need to be established and periodically reviewed in order to appropriately allocate City resources. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Comprehensive Guide Plan 2008 Update Executive Summary Plan Section – NATURAL RESOURCES (WATER QUALITY) Purpose of Section in the Comprehensive Plan The purpose of the Water Quality Section of the Natural Resources Element of the Comprehensive Guide Plan is to: 1) provide for adequate protection, preservation and enhancement of water bodies, wetlands, ground water recharge areas and wildlife habitat; 2) control runoff and erosion to prevent negative impacts to the City's water quality, plant communities and natural habitat; and 3) ensure the quality of lakes, wetlands, and streams meets or exceeds regional, state, and federal requirements and community expectations. Status of Work to Date Much has been accomplished since the City of Eagan adopted its first Water Quality Management Plan (WQMP) in 1990. In 1996, the U.S. Environmental Protection Agency recognized Eagan's program as tops in the nation. Despite a 40 -percent increase in population since 1990, water quality in the top seven recreational lakes has stayed the same or improved. In a 2005 scientific survey of City residents, 99 percent said good water quality was very or somewhat important: 0 Despite our successes, some lakes will not meet new water quality standards mandated by state and federal regulations. To stay on top, the City must be able to evaluate, include, and adapt to changing • regional, state, and federal directives for urban stormwater and wetlands management, in addition to public expectations. A major challenge is to cavy out a "state of the art" water quality program—in a nearly fully developed community with existing storm drainage infrastructure—in a cost-effective way, while acknowledging ever increasing demands for limited financial resources. In 2005, to help meet these challenges, .the City Council retained the consulting firm of Bonestroo, Rosene, Anderlik & Assoc. to prepare an upgraded Water Quality Management.Plan (WQMP) and also established a 13 -member Water Quality Task Force to guide development of the WQMP. The objectives of this work were to build on the successes of the 1990 WQMP; to consolidate and incorporate relevant policies, plans, and programs instituted since 1990; and to position the City to address efficiently and effectively the issues and needs of its surface water resources for the next 15 years. On October 17, 2006, the City Council will be presented a draft WQMP for acceptance and authorization of a 2 -month public review from October 18 to December 18, 2006. A Public open house has been scheduled for November 13, 2006, from 5:00 to 7:00 p.m. in the Eagan Room. A Public Hearing is anticipated to be set for February 6, 2007, specifically addressing wetland management strategies within the WQMP with a formal decision to adopt or modify the WQMP expected at the close of the hearing. Examples of Emerging Issues and Trends _ • Compliance with evolving federal and state water quality and stormwater requirements (i.e., stormwater pollution prevention, non -degradation, Impaired Waters/Total Maximum Daily Loads) • Development of policies/regulations for new and re -development activities regarding impervious surfaces, infiltration, best management practices, etc. • • Development of individual lake management plans; associated capital improvement projects. • Other – The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Q,3 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — HOUSING PLAN Purpose of Section in the Comprehensive Plan The purpose of the Housing Section of the Comprehensive Guide Plan is to identify the City's vision and expectations for housing opportunities throughout the City. Well built and well maintained housing in safe, attractive neighborhoods contribute to the high quality of life in Eagan. Likewise, the provision of adequate municipal and support services and the protection and enhancement of the City's natural environment help preserve neighborhood quality and character. Status of Work to Date The Housing Section of the current Comprehensive Plan Land Use Section has been generally reviewed by the Advisory Planning Commission in a Workshop setting and the Dakota County Community Development Agency (CDA) along with Maxfield Research provided the commission with a presentation of the recently completed county -wide housing study, as it relates to Eagan. Planning staff is also working with the Met Council, Census data and other sources to identify • demographic trends that will affect Eagan over the next 10-20 years. Examples of Emerging Issues and Trends 11 • An aging population, primarily due to the Baby Boomer generation beginning to reach retirement age in the next few years, will have an impact on housing from demand to maintenance. • Life Cycle Housing (providing housing opportunities for all ages) will continue to demand attention as the largest demographic growth population being those 62 and older. • The Dakota County CDA housing study indicates that needs for senior housing and workforce housing will continue to grow over the term of this plan. The study further indicates that it will be unlikely that conventional single family detached will be affordable for these demographic groups. • Real estate forecasts, Metropolitan Council studies and the CDA study suggest that demand for various types of attached and shared maintenance housing will continue to grow. • As the housing stock ages, maintenance and preservation efforts will become increasingly important to discourage deterioration and ensure protection of residential land values., • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Qf Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — ECONOMC DEVELOPMENT Purpose of Section in the Comprehensive Plan The purpose of the Economic Development Section of the Comprehensive Guide Plan is to define the City's expectations and strategy to encourage the continued investment and reinvestment in businesses, property and fixed assets in ways that will bring about the creation of permanent, high quality jobs and support a strong, diverse tax base within the community. Status of Work to Date In 2006, the Economic Development Commission was disbanded and work related to economic development activities and policies was assigned to the Economic Development Authority. As a consequence, a preliminary update of the Economic Development Section of the 2000 Comprehensive Guide Plan has not been completed to date. It is anticipated that the EDA would be asked in early 2007 to define a process by which it would facilitate an update of the plan for consideration with the remainder of the Comprehensive Plan. Alternatives for such a process include a formal study, a facilitated EDA review of the current Plan Section, survey input or other alternatives that may be deemed appropriate at that time. Jon Hohenstein will work with the EDA to coordinate the review at that time. Examples of Emerging Issues and Trends • • Expanding influence of information technologies in all types of businesses. The importance of high quality, redundant, high speed internet services to businesses will be key to meeting those needs. • As commercial industrial build out occurs and existing facilities age, the need to reuse, revitalize or redevelop certain properties will become increasingly important to meet continued demand for business expansion and location within the community. • Eagan has benefited by diversity in its business community and has been buffered from economic cycles for that reason. The City will benefit by continuing to position itself to support diversity in the future. • Continued importance of transportation industries due to the City's freeway access and proximity to the airport. • Changes in businesses and their products are leading to the increasing presence of a variety of home based businesses and possible interest in live -work land use alternatives. • Increasing interest in public financing incentives for both expansions and locations of businesses will underscore the importance of the City's Business Assistance Policies. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. 11 • Comprehensive Guide Plan 2008 Update Executive Summary 0 Plan Section — COMMUNITY FACILITIES Purpose of Section in the Comprehensive Plan The purpose of the Community Facilities Section of the Comprehensive Guide Plan is to describe those facilities that serve the public interest and contribute to the sense of community in Eagan. These include schools, libraries, municipal facilities, museums, cultural sites and telecommunications facilities. Status of Work to Date City staff will work with the school districts, county and other agencies to provide an update of this section. In the area of telecommunications, however, significant work has occurred in recent years. The work done to date will lead to discussions of how this topic is positioned in the Comprehensive Plan Update. Specific activities have included: • Technology Task Force — Tom Garrison — The Technology Task Force, assisted by Community Technology Advisors, developed a Technology Plan'that addresses specific policies and action steps associated with the provision of high speed internet to all parts of the community. The Task Force identified a multi -layered strategy including wired and wireless technologies and goals for further investigation of their implementation. • Technology Working Group — Tom Garrison — One of the recommendations of the Task Force was the creation of an ongoing Working Group to further develop the concepts and action plans associated with the Technology Plan and other emerging issues in the high speed intemet and information technologies areas. • Draft Telecommunications Comprehensive Plan Section — Jon Hohenstein and Mike Ridley - The Council authorized the hiring of Community Technology Advisors to take the next step of drafting a prospective Comprehensive Plan Section for high speed intemet telecommunications. The draft has been reviewed and commented upon by the Working Group and will be forwarded to the APC for further review as part of the Plan Update process. • As directed by the Communications Committee of the City Council, the Tech Working Group will also be addressing policy options for Eagan to obtain "world class" Internet connectivity & speeds. Examples of Emerging Issues and Trends The availability of high quality, redundant, high speed intemet service is emerging as a key factor in economic development and quality of life with health care, government and education services moving online. Many cities are examining code requirements, so-called `open trench" opportunities and other measures to encourage technology deployment and ensure businesses and homes are wired for the future. The Communications Committee of the City Council has asked for a summary of the policy opportunities. • The convergence of technologies will make it important to define a policy that addresses • not only high speed intemet, but the relationship between the technology infrastructure and the providers of telecommunications services. • The City is beginning to make policy decisions related to its use ofthe conduit loop installed in cooperation with ISD 196. • To the extent that a Telecommunications Subsection relates to more than high speed intemet, it should reference or take into account the emerging challenges and opportunities related to cable television and local access programming, High Definition TV and Internet Protocol TV (IPTV.). • The City will need to determine the appropriate Plan section for this topic in the future. • Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • is Q3 October 5, 2006 Orfleld Laboratories Inc PREPARED FOR Mr. Jason Ziemer City of Eagan 3830 Pilot Knob Road Eagan, MN 55122 Phone (651)675-5014 Fax (651)675-5012 . e-mail jziemer@cityofeagan.com PREPARED BY Elliott B.

The City of Eagan contracted week-long noise measurements before the new runway was completed, and again after the new runway began use. These measurements show some.trends through qualitative analysis which we may generalize to certain areas of Eagan. Statistical analysis somewhat supports these generalizations. . In the western part of Eagan, day-to-day levels were relatively consistent before the new runway. Now the new runway is operational, and the western part of Eagan experience higher noise levels on days where departures are routed south off runway 17/12. At the same time, northeastern Eagan is experiencing slightly lower noise levels now that the new runway is in use. This is likely due to lower use of those runways facing that area of Eagan. In general, the northeastern area of Eagan also experiences the same higher noise levels on days with southerly routed departures.

In June 2005, the City contracted Wyle Laboratories to conduct the initial measurement set before the runway opened. The new runway began use October 27, 2005.Orfieid Laboratories conducted a second measurement set in June 2006. The second measurement was executed to be similar to the first in most respects. In order to get a as true a comparison as possible, the same equipment and settings were used as in Wyle Lab's initial measurement. OVERALL COMPARISON The day -night average sound level was measured at ten locations. The averaging period was week in June of 2005, before runway 17/35 was complete, and June of 2006, after runway 17/35 was operational. Figure 1 shows the before/after comparison for each site. Locations are identified in detail in Appendix B. The day -night average, expressed LoN or DNL, is the equivalent sound level over a 24-hour day with 10 dB added to nighttime levels (from 22:00 to 07:00). This is the preferred metric of the Metropolitan Airports Commission (MAC), as well as the Federal Aviation Administration (FAA). 70 65 R 60 "q a e 55 0 50 45 o t M r N 4 40 i m 4 35 30 Ske 1 Ske 2 Site 3 Site 4 Sfte 6 Slee 6 Site 7 Site 8 Ske9 Site 10 Figure 1: LoN Comparison Orfleld Laboratories Inc Project New Runway Noise Monitor Client City of Eagan At some locations, the overall levels increased, and at other locations they decreased. One should not read too much into this direct comparison. There are many variables, other than the new runway, which may cause the change in result. Some of these factors are explored below. RUNWAY USE STATISTICS The number of over -flights will greatly impact the noise level. The Minneapolis Airports Commission keeps records of their runway use statistics, and the daily statistics are easily accessible. These data are used in this analysis, here qualitatively, and later statistically. The runway use provides an estimate of traffic over the measurement sites. Flights will differ in elevation and direction depending on weather conditions and their origin or destination. The number of overflights at a location will correlate well with runway use,. though runway use does not directly predict overflight. 2000----------------------------- ----------------------------- --------- ------------------- ---------------- '0 1500 -'- ---- -- m now ®4/22 17/35 1000 ',X,h�{ � il�6 ®12RI30L J11"i u: Iii` 4}kl{ a 12U30R v' 500 - ---- m Y4 m 0 - ---- ---- 'rs -- Week Week Week beginning beginning beginning 6/13/05 6/13/06 6/20/06 Figure 2: Runway Use over Measurement Periods The overall runway use is shown in Figure 2. The first thing to notice is runway 17/35 is handling approximately 13% of the traffic during the 2006 measurement periods. Orfleld Laboratories Inc Project New Runway Noise Monitor Client City of Eagan The next observation is there were approximately 10% more flights over the first week — before runway 17/35 was operational. This may have an effect on the noise levels — namely understating the noise levels over the 2006 measurement periods. Normalizing the measurement result to the runway traffic is one way to estimate the rough impact of this change. It would depress the 2006 overall LDN measurement by 0.5 dB, a relatively insignificant change for a week-long duration. 1000 goo 600 m u 700 ®SW z a 600 ®SE C ■S E 500 NW e a 400 NE m v 300 N a a 200 a m 100 0 12Figure 3: Direction of runway use Figure 3 shows the runway use for each runway, and the direction of the runway used. That is, departures which take off towards the south are grouped with arrivals approaching from the south. We will analyze these southern flights to estimate the over -flight traffic over Eagan. Daily flights arriving from or departing to the south are shown in Figure 4, Figure 5, and Figure 6. Runway 12L/30R and 12R/30L run parallel to each other, from the northeast to the southwest. These runways face the north end of Eagan. Runway 17/35, the new runway runs south over the western end of Eagan. The south end of runway 4/22 faces into Bloomington, and only some of the departures will turnto fly over Eagan. This runway is used very little, so the impact of these statistics will be insignificant..

Wind conditions determine the direction to land and take -off. Runway use during the first measurement period in 2006 is consistent with the period in 2005. Runway use over the second measurement period in.2006 has a much higher number of arrivals than departures. These differences are shown in Figure 7.

Arrivals will approach in-line with the runway, at a IoWer altitude, and with a lower engine speed. Departures will use a greater engine speed, and after clearing the end of the runway climb and tum as quickly as possible. The noise impact of each will depend on the location of the site, and its relation to the runway. QUALITATIVE ANALYSIS Qualitative analyses are performed in this study by examining the results and observe trends and relationships. From this examination we infer that one event may cause another event. At its essence, the qualitative analysis is a means to construct hypotheses. Graphs of data are the most useful tool to visually discover these potential trends and relationships. Appendix C contains the hourly and daily results shown in graphs. STATISTICAL ANALYSIS The daily measurements and daily runway use statistics were entered into statistical analysis software. Table 1 shows the Pearson correlation between individual measurement sites and runway use. The Pearson correlation coefficient measures linear correlation or predictability between two variables. The value of the coefficient varies between -1 and +1. A value of +1 indicates that one variable can be predicted perfectly by the other. A value of -1 means the same thing except that the variables are inversely related. A Pearson correlation of 0 indicates that neither of the two variables can be predicted from the other. by using a linear equation. ff it Project New Runway Noise Monitor s Client City of Eagan Table 1: Pearson.Correlation of Daily Noise Levels Correlation is significant at the 0.01 level (2-talled), rboid, underline] Correlation Is significant at the 0.05 level (2-tailed).

This is mainly due to the small number of cases (days) and the great variability in aircraft noise from day-to-day. In general, the correlation coefficients somewhat support the qualitative analysis at most sites. .76zldk�-]101:N]AI:Id1v1I11L1f PYt*� r_111UW&i &9Yll=111i The Site 1 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway'17/35 in 2006, which were not present in the 2005 measurement. A qualitative analysis of the daily and hourly noise levels show the behavior of noise at Site 1 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways. This position is approximately 4 % miles south -by -southeast of runway 17/35. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased noise levels in L,q, LDN, L1o, and Lot. The statistical analysis generally supports the qualitative analysis. Noise levels at Site 1 correlates very poorly with all runway use, except for runway 17/35. It shows some correlation between departures off the south end of runway 17/35, though the correlation is not statistically significant. ANALYSIS AT SITE 2 The Site 2 day -night average level over the 2006 measurement period decreased overall from the 2005 measurement. This is due to a decrease in the nighttime hourly average levels (I -Q. There is no clear explanation for the nighttime measurements. The daytime average levels did increase from the 2005 measurement to the 2006 measurement. A qualitative analysis shows that, over the 2006 measurement, the Leq LDN, LSO, 1-90, and Les measurements were higher on days with heavier departures. However, 1-10 and Lot are much higher than 1-50 at other sites on these days. The difference between 1-10 and L50 is smaller at this site on the departure -heavy days. This may be due to departures, this far from the airport, are high enough in elevation that they can be heard over, a longer duration. The engine noise builds slowly and dies slowly, rather than getting a shorter blast of engine noise. This position is approximately 51/2 miles south -by -southeast of runway 17/35. On days with heavier arrivals, L10 and Lot are much higher than at this site. This may be due to arrivals, at their lower elevation, exposing this site to shorter durations of their engine noise. The engine usually runs lower at arrivals, so the overall noise dropped on these days. Most sites are within a mile of a either Highway 77 or Interstate 35E (excepting Site 5, Site 6, and Site 9). This site is approximately a half -mile from both highways, one on either side. This may also contribute to the noise, as it does at other sites. Rush hour traffic is reflected in the statistical measurements as well. Project New Runway Noise Monitor 0 Client City of Eagan Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures, are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is consistent between sites 2, 3, 8, 9, and 10. The departures off 17/35 are somewhat correlated with higher noise levels at Site 2. Interestingly, lower noise levels are correlated with arrivals onto 17/35 with statistical significance. ANALYSIS AT SITE 3 The Site 3 day -night average level over the 2006 measurement period did not differ much overall from the 2005 measurement. The daily and hourly noise levels show the behavior of noise at Site 3 is somewhat consistent with the noise at other nearby sites. This position is approximately 5 miles south -by - southeast of runway 17/35. A qualitative analysis shows that, during the 2005 measurement period, the daily average noise levels (LON) varied little, except nighttime levels were responsible for higher LoN some days. The statistical metrics (L„) while varying hour -to -hour, exhibited similar behaviors day-to-day. During the 2006 measurements, the daily Laq, LpN, L,o, and Loi results seemed to increase on days where runway 17/35 was mainly used for departures. The meter did not measure a full Day with heavy departures over Eagan. This was due to an overnight meter malfunction. Perhaps if the departure -heavy days been measured in full, the overall results would have been higher at this location. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is consistent between sites 2, 3, 8, 9, and 10. There is a statistically significant correlation between noise levels and the number of flight departures on runway 17/35: At Site 3, like site 2, arrivals off the 17/35 runway are correlated with higher noise levels, but without statistical significance. ANALYSIS AT SITE 4 The Site 4 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The behavior of noise at this site, however, is inconsistent with the noise at other nearby sites, nor consistent with its relation to the airport runways. This position is approximately 6'/ miles south - by -southeast of runway 17/35. This monitor location overlooked a busy city street. Most of the noise was road traffic, as evidenced by the traffic cycles, especially in the Lso measurement. It was more pronounced in the 2006 measurement than the 2005 measurement. Noise levels were consistent day-to-day (a little lower over the weekends), whereas most other sites exhibited different noise characteristics depending on the number of arrivals versus departures over Eagan. V In Wield Laboratories Inc , N , Project New Runway Noise Monitor Client City of Eagan Statistical analysis shows correlations which do not represent the probable overflight noise. This may be due to the fact that the flight arrivals over Eagan heavily outnumbered departures during the 2006 measurement, which was also, in general, higher in noise level. The data from this site was heavily influenced by the traffic noise. ANALYSIS AT SITE 5 The Site 5 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. Despite this, the behavior of noise at Site 5 is inconsistent with expatiations and the noise at other nearby sites. Note that the normal diurnal cycle disappears after June 21, 2006. Usually every metric drops through the small hours of the morning. This daily cycle can be observed on the hourly percentile level graphs. At Site 5, the 1-01 and Lto measurements remain relatively constant. This is likely due to a babbling brook in the neighbor's back yard that ran down the hill. The brook was still under construction Tuesday and Wednesday. The construction may account for much of the high daytime levels. The brook was running constantly since Wednesday, and the sound levels never dropped much below 45 dB at the monitoring station. This position is approximately 6'Y2 miles southeast of runway 17/35. The 41 measurement may reflect a higher number of departures than arrivals over Eagan, but it is not significant. Statistical analysis showed correlations which were similar to Site 4, but not to other sites. There is probably a similar reason for this: the noise levels were generally higher during the 2006 measurement, and the number of arrivals greatly outnumbered the number of departures during the same period. ANALYSIS AT SITE 6 The Site 6 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway 17/35 in 2006, which were not present in the 2005 measurement. This position is approximately 6'/2 miles southeast of runway 17/35. Qualitative analysis shows that, despite being further away, the behavior of noise at Site 1 is consistent with closer sites and consistent with its relation to the airport runways. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased daily and hourly noise levels in L,q, LDN, L10, and Lot. The statistical analysis generally supports the qualitative analysis. Noise levels at Site 1 correlates very poorly with all runway use, except for runway 17/35. It shows statistically significant correlation between noise levels and departures off the south end of runway 17/35. 0 Project New Runway Noise Monitor Client City of Eagan ANALYSIS AT SITE 7 The Site 7 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway 17/35 in 2006, which were not present in the 2005 measurement. Qualitative analysis of the daily and hourly noise levels show the behavior of noise at Site 7 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways, This position is approximately 5 miles southeast of runway 17/35. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased noise levels in Lq, LDN, 1-11), and Lol. Site 7 was located on top of a hill, without any nearby trees or structures. Without anything to break up the sound of overflights, this site had higher results than the other sites. Overflight noise would be recorded from further away, and the ground effect will also moderately increase the noise. Traffic noise probably also influenced both the 2005 and 2006 measurements at Site 7. Statistical analysis is contrary to the qualitative analysis. Reasons for this are not immediately apparent. For answers, this may require additional research, testing, or analysis. ANALYSIS AT SITE 8 The Site 8 day -night average level over the 2006 measurement period decreased overall from the 2005 measurement. In part, this is due to a decrease in the nighttime hourly average levels (L,q). Also, for days with a light number of departing flights, the daytime level was lower in 2006 than it was in the 2005 measurement period. There is no clear explanation for the nighttime measurements, nor the decrease in levels on particular days. During the 2006 measurement period, behavior of noise at Site 8 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways. This position is approximately 4 miles southeast of runway 17/35. Days where runway 17/35 was mainly used for departures the daily and hourly noise levels also showed increased noise levels in L,q, LDN, L,o, and Lot. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is also consistent between sites 2, 3, 8, 9, and 10. The departures off 17/35 are somewhat correlated with higher noise levels at Site 8. Interestingly, lower noise levels are correlated with arrivals onto 17/35 with. statistical significance. Project New Runway Noise Monitor Client City of Eagan ANALYSIS AT SITE 9 The Site 9 day-night average level over the 2006 measurement period decreased overall from the 2005 measurement. The overall decrease is expected, due to fewer flights over Eagan from runways 12U30R and 12R/30L in the 2006 measurement, which were diverted to runway 17/35. The daily and hourly noise levels show the behavior of noise this site is consistent with the noise at the nearby Site 10, and consistent with its relation to the airport runways. This position is approximately 5 miles southeast of runway 12R/30L. Sites 9 and 10 are closer to the 12U30R and 12R/30L runways than to the 17/35 runway. During both the 2005 measurement period and the 2006 measurement period, days where runways were mainly used for departures over Eagan also showed increased noise levels in L q, LDN, L,o, and Lot. In general, all metrics Site 9 were lower in 2006 than they were in the 2005 measurement. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. There is Tittle correlation with runway 17/35 at this site. That is reasonable, since Site 9 and 10 are located under the flight path of the 12/30 runways. ANALYSIS AT SITE 10 The Site 10 day-night average level over the 2006 measurement period decreased overall from the 2005 measurement. The overall decrease is expected, due to fewer flights over Eagan from runways 12U30R and 12R/30L in the 2006 measurement, which were diverted to runway 17/35. The daily and hourly noise levels show the behavior of noise this site is consistent with the noise at the nearby Site 9, and consistent with its relation to the airport runways. This position is approximately 2'% miles southeast of runway 12R/30L. Sites 9 and 10 are closer to the 12U30R and 12R/30L runways than to the 17/35 runway. During both the 2005 measurement period and the 2006 measurement period, days where runways were mainly used for departures over Eagan also showed increased noise levels in Lq, LDN, L,o, and Lor. In general, most metrics at Site 10 were similar in 2006 than they were in the 2005 measurement. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. There is little correlation with runway 17/35 at this site. That is reasonable, since Site 9 and 10 are located under the flight path of the 12/30 runways. 1 Orfleld Laboratories Inc 0 Project New Runway Noise Monitor Client City of Eagan CONCLUSION In general, the new runway 17/35 does seem to have an impact on noise levels in the City of Eagan. Since the overall number of flights during the measurement periods were less after the new runway became operational, there is not a direct comparison between the "before" and "after condition on a city-wide basis. Certainly, the impact is dependant on location, and the direction of arriving and departing flights. The City of Eagan should continue to monitor aircraft noise levels. )field Laboratories Inc • , A N D Project I New Runway Noise Monitor Client City of Eagan.

FACTS: ■ Elliott Dick, Orfield Laboratories, will present and discuss the results from the phase I - phase II noise comparison study. ■ Wyle Laboratories conducted the initial noise study in June 2005, prior to the new north - south Runway 17/35 opening. ■ The city hired Orfield Laboratories to perform the follow up noise study, post -runway opening. That study was completed in June 2006. ■ The raw data collected during the phase II study showed little, if any, change from data • collected during the pre -runway study. Orfield was hired to compare and analyze "results from Phase I and Phase II studies.

Update on Preplanning Efforts to Ensure Continuity of Government Operations in the Event of an Pandemic ACTION TO BE CONSIDERED: No Formal Action Required FACTS: • At a May 2006, listening session, the Eagan City Council received a briefing about the need for city staff to begin developing a continuity plan in the event of an Avian Influenza Pandemic. • A committee of city staff members has been meeting regularly and is in the process for developing a plan for future council consideration. • • It is anticipated the council would be able to review the plan in December, 2006. ATTACHMENTS: :Memo from James McDonald, Chief of Police, to the Mayor and Council regarding Avian Influenza planning efforts. Attachments on pages through • a CitOl �n nn POLICE DEPARTMENT a�Ian MEMORANDUM DATE: October 5, 2006 TO: Eagan Mayor and City Council Members FROM: James S. McDonald, Police Chief SUBJECT: Planning Update in the event of an Avian Influenza Pandemic Purpose At a May 2006, Eagan City Council Listening Session, the Mayor and Council received a briefing outlining the need for staff to begin planning a city response to a potential Avian Influenza Pandemic. This document will attempt to update the mayor and council on planning initiatives. • Brief History and Current Status of Avian Influenza As described previously, Avian Influenza (flu) is a virus that is highly contagious and mainly effects birds. The current Avian Flu, identified as H5N I, has been found in Africa Asia, and Europe where it has caused the death or destruction of an estimated 150 million birds. The virus is generally "species specific," but has crossed the "species barrier" and infected humans. Although there are an extraordinary high number of casualties in birds, there have been a low number of human deaths related to the virus. Statistics compiledearlier this year note there were approximately 148 human deaths reported world wide. The humans who died from the H5N 1 virus had lived in the undeveloped countries of Asia where farmers lived/worked in close proximity to poultry who had the disease. Although, it is difficult for humans to get the H5N 1 virus directly from birds, it is believed humans inhabiting an environment where they butcher infected fowl or come in contact with bird feces are at a higher risk of contracting the disease. Transmission of the H5N1 virus from human to human is very unlikely. However, if the virus were to mutate, or "re -assort" with another virus that is readily transmitted between humans, a stage will be set for a worldwide pandemic. It should be noted, health officials are studying a case in Indonesia where a human to human transfer among family • members may have occurred. 3 Assumptions in the Event of an Pandemic Page 2) • According to information from the Minnesota Department of Public Safety, the following planning assumptions should be considered by local units of government in their continuity of government planning. A. A pandemic could last 6-8 weeks and include several waves over the course of a year. B. Up to 30 percent of the workforce could be out sick during a pandemic. Absenteeism could reach 40 percent during the peak of a pandemic. People may decide to stay home to care for family members or for children when schools are closed. Fear of exposure may lead to lower rates of absenteeism before an actual outbreak begins. C. Employer flexibility will be necessary and might include staggered shifts, expansion of physical space between work stations, or allowing employees to work from home. D. Leave policies may need to be flexible. E. Employees may need personal protective equipment (PPE) to maintain priority • service functions. This requires implementation of PPE policies and procedures and ensuring the required training and fit testing is done. F. Availability of supplies will be limited because of hoarding, combined with limited production and transportation limits: G. Administrative rule waivers and alternate service delivery systems may be necessary to maintain priority service functions. Local jurisdictions should develop policies for reduced service delivery. H. Community buildings may need to be used as alternate care facilities and standards of care may need to be adjusted when hospitals are overwhelmed. Local jurisdictions need to make sure they can staff existing health care facilities before establishing alternate health care facilities. (Ensure that these alternate sites can be staffed locally prior to opening. Make sure that the facility owners/operators know they are in the local plan.) I. Up to two percent of the 30 percent who fall ill may die. This rate could overwhelm mortuary and burial services. Local jurisdictions may need to assist local mortuary services. J. Assistance from outside organizations, county, state and federal government will • be limited. • Page 3) Current Status of City Efforts Since May, 2006, employees from police, fire, community development, human resources, public works, parks, information technologies, communications, and emergency management have been working to develop a plan that would help the city manage a pandemic scenario. While using the above assumptions along with trying to forecast the potential impacts on city employees and community members, the committee has been reviewing operations and evaluating the potential implications on service delivery in the event our workforce is impacted by a pandemic. Ultimately, the evaluations will be placed into a pandemic plan that will be reviewed by senior management. After the review, the document will be forwarded to the city council for consideration. It is anticipated the plan will be forwarded to the council for approval in December, 2006. Conclusion Although the committee is carefully evaluating service issues that may need to be managed in the event of a pandemic, it is important to realize the difficulty of developing • steadfast plans when you have to rely upon a workforce that may not be available. Consequently, any plan developed will need to have some inherent flexibility to reassess any unforeseen issues that may arise. • Thank you for your consideration in this matter.

REVIEW PROPOSED BURNSVILLE/EAGAN COMMUNITY TELEVISION (BECT) 2007 OPERATING BUDGET DIRECTION TO BE • To provide direction, if any, to staff regarding the 2007 Burnsville/Eagan Community Television Budget and to direct that it be placed on a future regular City Council meeting consent agenda for formal ratification. . BACKGROUND: • Community Television operates under a joint powers agreement with the cities of Ir. Eagan and Burnsville. • Equal contributions of $103,500 each by the member cities remain the same. • With the exception of a 3% cost of living adjustment and an increase in hours for part-time cablecasters (to facilitate Web streaming), the operating budget is essentially unchanged from 2006. • Capital expenditures in 2007 are up significantly, reflecting underspending on replacement in 2005 and early 2006, and the anticipated need to replace studio equipment in. 2007. Capital spending was originally budgeted and approved at more than $136,000 for 2006, but by year's end staff estimates spending will only • amount to $76,000. That additional $60,000 will be carried forward into 2007. • Note that should BECT later relocate to a different facility, studio systems and cameras can also be relocated. Without upgrades in 2007, BECT would likely be left without a functioning facility. • Per direction of the two city councils, the city attorneys of Burnsville and Eagan are in the process of wrapping up a 1 -year lease at the current facility to preserve maximum flexibility bothin teams of national franchise legislation and/or expanded partnerships in Dakota County. • The 2007 budget is modeled on normal operations. Should new federal legislation pass, staff will return to both city councils with any necessary budget revisions or reconsideration. • Even without changes by Congress, as noted on the attached chart, a plan to fund capital improvements beyond mid -2010 is necessary. While this is actually an improvement on earlier 2004 fund balance projections, much more work remains to be done. • Long-term funding, location and facility -size discussions will be a major focus of the 2007 work plan, along with generating additional outside revenue for the facility. • It may also be of interest for the City Council to note that the Telecommunications Commission received the findings of a Subscriber Survey from'Dr. Bill Morris of Decision Resources. The survey was commissioned to determine satisfaction with services offered by Comcast, viewership, and value • perception for community television programming. 400 subscribers were surveyed in March/April of 2006. • Overall customer service ratings for Comcast were positive with 80% giving a "good" or "excellent" rating. Only 6% said customer service was "poor" Ir. • As for local programming, 83% said it was important or somewhat important to • have available. • City Council meetings are the most highly viewed public meetings with 7% saying they watch frequently and 48% watching occasionally. • The survey presentation is available on cable television Channel 16.

STATUS REPORT - 2008 COMPREHENSIVE PLAN UPDATE DIRECTION TO BE CONSIDERED: To review/comment and/or provide staff with direction regarding the Plan Update. FACTS: Earlier this year, the City Council directed staff to begin the process of updating the Comprehensive Plan. A fall check point, with the Council, was built into that process. ➢ In Minnesota, authority for land -use planning and regulation is vested primarily in local governments. The Metropolitan Land Planning Act, a state law first passed in 1976 and amended several time since, requires local governments in the seven -county Twin Cities area to develop local comprehensive plans. ➢ The plans must contain a number of elements, among them: • o Maps and data showing current and future land use o A Housing plan o A surface water management plan o Plans for public facilities, like transportation, sewers, and parks is ➢ The Metropolitan Land Planning Act requires communities to review and update their local comprehensive plans at least once every 10 years. Local plan updates are due in 2008. ➢ Communities then submit their plans to the Metropolitan Council, which determines if the local plans: o Conform to metropolitan system plans o Are consistent with other adopted plans of the Metropolitan Council o Are compatible with each other ➢ Local governments may not implement any measures that would allow development in conflict with the Comprehensive Plan reviewed by the Metropolitan Council. ➢ Additional Council check points and opportunities for public input will occur throughout 2007. Staff would propose that the next checkpoint occur in the spring of 2007 and that a schedule be established at that point for the remainder of the review and public input process. 10 ➢ The background attachments are presented in an executive summary form. As with the • budget presentation in August, staff have a limited formal presentation and will step through the section summaries to permit the Council to review and comment on the sections as appropriate. ATTACHMENTS: (1) Executive summary/status reports, by Comprehensive Plan.section, are attached on pages through. • r� U Comprehensive Guide Plan 2008 Update • Executive Summary Plan Section — LAND USE Purpose of Section in the Comprehensive Plan The purpose of the Land Use Section of the Comprehensive Guide Plan is to define the City's vision and expectations for land use throughout the City. The 1995 Amendments to the Metropolitan Land Planning Act require that local governments achieve consistency between their Comprehensive Plan and Zoning Ordinance. While the Comprehensive Plan describes the vision for how Eagan should develop over the next 10-20 years, the Zoning Ordinance is the tool for achieving that vision by specifically regulating the type, scale and location of development. Certainly the overall character of the City has changed over the past twenty years from a mostly developing community to a developed community. To date approximately 96% of the land in Eagan has been developed. Therefore, significant changes in development patterns are not anticipated in the 2008 Land Use Plan. However, changes will continue to occur in response to new trends and as older uses redevelop to new uses. Status of Work to Date The Land Use Section of the current Comprehensive Plan Land Use Section has been generally • reviewed by the Advisory Planning Commission in a Workshop setting and planning staff will complete an inventory that will define existing inconsistencies and highlight current vacant and underutilized land for discussion in the coming months. • Additionally, every residential property will be viewed in 2007 via a windshield survey that will confirm the general site conditions and use. Examples of Emerging Issues and Trends • An aging population (as the Baby Boomer generation works through its life cycle) will have an impact of some kind on Land Use from residential, fewer persons available to purchase boomer housing, to commercial/industrial, fewer persons entering the work force. • As commercial industrial build out occurs and existing facilities age, the need to reuse, revitalize or redevelop certain properties will become increasingly important to meet demand for business growth and/or reallocation within the community. • Eagan has benefited by diversity in its business community and has been buffered from economic cycles for that reason. The City will benefit by continuing to position itself to support commercial/industrial diversity in the future. • Changes in businesses and their products are leading to the increasing presence of a variety of home based businesses and possible interest in live -work land use altematives. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. )a Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — TRANSPORTATION PLAN .Purpose of Section in the Comprehensive Plan The purpose of the Transportation Element of the Comprehensive Guide Plan is to: 1) identify existing and future transportation needs in terms of the roadway and non -roadway system; 2) influence decisions that the City is making by anticipating the character, magnitude, and timing of future transportation demand; and 3) provide for an integrated transportation system that will serve the needs of its residents, support the City's development plans, and complement the metropolitan transportation system that lies within its boundaries. In addition to guiding development of the City's transportation system, the plan fulfills the requirements of Minnesota Statutes Section 473.859 (subdivision 3) requiring a public facilities plan section within a comprehensive plan to be submitted for Metropolitan Council approval. Status of Work to Date Is Separate Comprehensive Transportation Plans have been prepared and/or updated previously to meet the Metropolitan Council's Comprehensive Guide Plan requirements. In 2006, the consulting firm of SRF Consulting Group, Inc. was again retained to prepare this next update. To date, the process is approximately 20% complete and a final draft will be ready for formal review • by February 20, 2007. Copies will be sent to adjacent communities and regional agencies for review and comment during the second quarter of 2007. There are no public reviews planned beyond those associated with the overall Comprehensive Guide Plan review. Complementary efforts that have been under taken since the previous plan update and that are currently underway including the following: • City of Eagan Transportation Infrastructure Needs Analysis (TINA) • CSAH 28 (Yankee Doodle Road) Corridor Study • Eagan/Inver Grove Heights North-South Corridor Study Examples of Emerging Issues and Trends Continued population and employment growth in the City, as well as surrounding communities, will result in increasing demand to the transportation system. Greater local and regional funding for transportation and transit improvements will need to be pursued to provide for adequate preservation and expansion of the transportation system. The community's growing desire for choice in transportation, including walkability within the City and improved transit service, will require coordinated and complimentary land use and transportation planning. Future transit opportunities include expanded transit service, Cedar Avenue BRT and Robert Street Corridor Transitway. Identification of transportation problems and opportunities in terms of roadway capacity, safety, functional classification, and jurisdiction may likely lead to changes requiring • 13 other agency approval or agreements. Some changes may provide additional financial burden to the City, while the lack of approval may limit funding opportunities. • The development of a Neighborhood Traffic Management Plan/Policy is very likely to address requests for reduced speed limits, stop signs, traffic calming, etc. • Creation of a "transportation impact fee" for all future development or redevelopment to address increasing transportation system demand and decreasing funding opportunities. • Increased emphasis on securing funding sources to complete the design and construction of the Ring Road. • Use of roundabouts versus traffic control signals. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — AVIATION/AIRPORTS Purpose of Section in the Comprehensive Plan The purpose of the Aviation/Airports Section of the Comprehensive Guide Plan is to define the City's relationship with the Minneapolis -St. Paul International Airport in the context of both its environmental impacts on the residential community and its benefits as an amenity for both the residents and businesses in the community, because of its proximity to the City. Status of Work to Date With its update of the Metropolitan Systems Plans in preparation for the cities' Comprehensive Plan updates, the Metropolitan Council incorporated its Aviation Plan into the Region's Transportation Plan. To conform with that approach, staff proposes to incorporate the City's Aviation/Airports Section into the Comprehensive Plan Transportation Section. Aviation will continue to be a defined subsection of the Transportation Section and the update has been initiated with that expectation. In 2006, the Airport Relations Commission and City staff have begun work on several activities that relate to the update of this Plan Section. Aviation/Airports Section Update — Dianne Miller — Staff and the Commission have • prepared a draft update and performed a preliminary review of issues and topics to be addressed. That work will continue in the months ahead. It is anticipated that the ARC. will hold its own public input meetings prior to incorporation of the draft into the formal plan for the APC's public review. North-South Runway Noise Monitoring Study — Orfield Labs — The City's pre and post opening noise studies have been completed and the results will be used to further define goals and policies relative to the new runway and its operation. Examples of Emerging Issues and Trends • The FAA's use of the North-South Runway continues to evolve. To date, it has resulted in operations different from what had been anticipated during the planning and environmental review processes. • The economic health of the airline industry will have direct, but opposite, impacts on Eagan's economic amenities and noise environment. • Continued conversion of hush-kitted aircraft to factory stage III aircraft will have a generally positive influence on single event noise levels. • The trend away from regional propeller planes and toward smaller regionaf jets may counterbalance some of that effect. • Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (SANITARY SEWER) Purpose of Section in the Comprehensive Plan The purpose of the Sanitary Sewer Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) project municipal demand on Metropolitan Council's interceptors and wastewater treatment plants; 2) specify areas to be served by the public sewer system 3) outline a program for addressing inflow and infiltration into the sewer system; and 4) set standards for private sewer systems, as applicable. The City is preparing the Sanitary Sewer Plan as a two step effort. Since the Metropolitan Council will not review a 2030 Sanitary Sewer Plan prior to receiving a 2030 Land Use Plan, the first step is to submit an Amendment to the already approved Sanitary Sewer Plan (originally submitted in 2000). In many aspects this Amendment will be identical to what will become the 2030 Sanitary Sewer Plan. Submitting the document as a 2020 Amendment allows Metropolitan Council to review the document and offer official comment's. These comments will assist the City in quickly turning this document into a 2030 Sanitary Sewer Plan that supports the over Comprehensive Guide Plan submittal. • Status of Work to Date Separate local Comprehensive Sanitary Sewer Plans have been prepared and/or updated in 1965, 1976, 1982, 1988, and 2000 in concert with the City's significant growth. In 2006, the consulting firm of Bonestroo, Rosene, Anderlik & Assoc was again retained to prepare both the Amendment to the current 2000 Plan and the ultimate 2030 Update. The Amendment is approximately 95% completed and will be submitted for staff review in mid October. A final draft will be ready for formal review by Metropolitan Council in late October or early November, 2006. Copies will be sent to adjacent communities for review and comment concurrent with the Metropolitan Council review. There are no public reviews scheduled beyond those associated with 'the overall Comprehehsive Guide Plan review. Examples of Emerging Issues and Trends • In the 2000 Sanitary Sewer Plan there was a large discrepancy between the City's projected flows and those of Metropolitan Council. The discrepancy was due to the City's flow projections for commercial land being reasonably conservative but not reflective of the actual flows generated by typical commercial properties in the City. In order to preempt dispute on sewage flows, the current Sanitary Sewer Plan projects flows using two methods. The first reflects "current trends" and uses lower flows from commercial properties based on historical flows records. These "current trends" flow estimates will be reported to Metropolitan Council and more closely match the Council's own predictions. The second method is "system design" and reflects the higher design flow for commercial property, similar to the 2000 Sanitary Sewer Plan. The "system • design" flows provide a trunk system that allows the City a certain measure of reserve capacity in the event that a high sewage generating use does appear within its borders. AV • In 2005, the Metropolitan Council instituted an Inflow/Infiltration (I & I) Surcharge • Program to eliminate the additional capacity within its interceptor system needed to serve excessive I & I. The Met Council established I & I thresholds, and communities that exceed this threshold are required to eliminate this excess flow within a reasonable timeframe. The 2030 Sanitary Sewer Plan Update will address the City's plan for reducing I & I below the established threshold. • Flow from the Minnesota Zoo in Apple Valley into Eagan's system accounts for the majority of the current documented excessive I & I. The 2030 Plan will better define the City and Zoo's responsibility toward this excessive I & I and the related financial surcharge. • The current Sanitary Sewer Plan and its flow projections include redevelopment and build -out of certain underutilized parcels within the City. These specific modifications to the land use plan will also include the Cedar Grove Redevelopment area. • Although not yet formally considered by the Eagan Council, the City of Rosemount's previously expressed interest in extending sanitary sewer service south of 1200' Street along the TH 3 corridor has been taken into consideration in calculating ultimate flows to properly evaluate the maximum impact on the entire system. • Other — The Council may identify other trends. and issues to be.addressed in the course of the Comprehensive Plan update process. F_ -I LJ 11 17 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (STORM SEWER) Purpose of Section in the Comprehensive Plan The purpose of the Storm Sewer Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) manage stormwater volume and rate control for flood. protection; 2) develop, operate, and maintain the public storm drainage system; 3) minimize erosion and sedimentation and 4) promote groundwater recharge. Status of Work to Date Separate local Stormwater Management Plans were prepared or updated in 1965, 1972, 1978, 1984, and 1990 in concert with the City's significant growth. In 1999, the consulting turn of Bonestroo, Rosene, Anderlik & Assoc. was again retained to update the 1990 plan. Near the proposed completion of the plan, the City was flooded in multiple areas as a result of the July 2000 Super Storm. All efforts on the plan were redirected toward the analysis and mitigation of the Super Storm. As a result of the flooding associated with the Super Storm, the scope of the plan update was modified to incorporate the analysis of the entire City to the level of a storm • event comparable to the July 2000 Super Storm. The plan was also revised to provide a more operational perspective on flood control at significant ponds within the storm sewer system. The update of the Stormwatei Management Plan was completed and formally approved by the City Council on January 17, 2006. Copies will be sent to adjacent communities for review and comment concurrent with the Metropolitan Council review. No public reviews have been scheduled, although the opportunity exists with the overall Comprehensive Guide Plan review. Examples of Emerging Issues and Trends • The comprehensive Stormwater Management Plan identifies a concept of providing for the managed conveyance of storm water flows from southeast Eagan into and through, as well as for, the Lebanon Hills Regional Park (LHRP). The proposed concept addresses past flooding of private property within the City and a County highway (Cliff Road). LHRP consists of approximately 1,400 acres, but does not have a managed surface water drainage system in place, although they have recently prepared a draft comprehensive drainage plan to manage the rate and volume of water that enters and flows through the park. On July 6, 2004, the City Council approved a project for constructing new storm sewer from southeast Eagan (Gun Club pond) into and through LHRP by way of Marsh Lake and McDonough Lake to the public system at Pond LP -51 and the Holland Lake lift station. City staff has communicated extensively with the staffs of Dakota County Parks and the Minnesota Department of Natural Resources. In order to construct the proposed improvements, approval will be needed from both of these agencies, as well as permission from the Met Council to work within LHRP. In the past, Dakota County has expressed objections to the amount of their proposed financial participation. However, a • sunset date of June 2007 for designated state funding ($500,000) for the improvements may encourage approval from the County. /Y • Compliance with evolving federal and state stormwater requirements (i.e. stormwater • pollution prevention, non -degradation and Impaired Waters/TNIDLs) will likely require additional staffing needs or consultant services. •' Development of policies/regulations for new development and re -development regarding Low Impact Development (LID) (i.e. impervious surfaces, infiltration, best management practices) may be required. • Long term maintenance of ponding areas for dry & wet stormwater storage volumes and the associated access to these drainage ponds will likely need to be addressed in order to maintain compliance with new requirements. • The lack of drainage and utility easements around some lakes, ponds and wetlands included as part of the public storm sewer system may incur significant acquisition costs. • Provisions for storm sewer design and the associated easements for a "July 2000 Super Storm" event are continuing to be requested by the public. Does the City raise the "standard" storm sewer design? • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • i9 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PUBLIC UTILITIES (WATER SUPPLY & DISTRIBUTION) Purpose of Section in the Comprehensive Plan The purpose of the Water Supply and Distribution Section of the Utilities Element of the Comprehensive Guide Plan is to: 1) project the future use and peak demand requirements of the community; 2) evaluate the quality, availability and dependability of supply resources; and 3) plan for the City's ability to treat, store and distribute potable water to all users in compliance with the Minnesota Department of Health standards. Status of Work to Date Separate Comprehensive Water Supply & Distribution Plans have been prepared and/or updated in 1965, 1969, 1976, 1982, 1988 and 1996 in concert with the City's significant growth. In 2006, the consulting firm of Bonestroo, Rosene, Anderlik & Assoc was again retained to prepare this next update meeting the Metropolitan Council's Comprehensive Guide Plan requirements as well. The update is approximately 95% completed and a final draft will be ready for formal review by October 31, 2006. Copies will be. sent to adjacent communities and regional agencies for review and comment during the first part of 2007. There are no public reviews planned beyond those associated with the overall Comprehensive Guide Plan review. • Examples of Emerging Issues and Trends While the metropolitan area is blessed with an abundant aquifer for potable drinking water supplies, it is limited. Ground water protection, conservation measures and alternative sources need to be evaluated to insure a reliable source for the City's future projected needs. The emergency and conservation sections of this plan will address various options and policies to encourage, or enforce as necessary, conservation measures to meet Metropolitan goals. The emergency plan outlines safety and security measures, and identifies potential interconnections with neighboring communities. Approximately five more wells are required to serve full build out of the city. General site locations have been identified for these wells based on previous ground water geologic studies. Future wells will be developed as demand occurs. However, design, construction and permitting of a new well facility takes approximately two years to complete. Therefore, it is important to continually re-evaluate the Capital Improvement Plan in light of the latest development and re -development plans. Several minor improvements are required at the Cliff Road Water Treatment Facility to improve operation of the facility and provide treated water to the expansion of the southeastern portion of the City. The needs of the Sperry Water Tower are marginal for future water supply and/or pressure requirements. An economic analysis should determine if it is cost effective to keep it as part of the water system or if it should be replaced with a more conventional low maintenance antenna tower for public safety and commercial uses. N Additional water storage may be required to adequately serve redevelopment of the is northeast area of the city. Previous Water Supply and Distribution Plans have proposed building a second ground storage reservoir adjacent to the existing Yankee Doodle Reservoir, on existing City property. This study has determined that an alternative site in the northeast redevelopment area provides a slight operational benefit over the original alternative of the second Yankee Doodle Reservoir. However, due to lower ground elevations in the northeast area, the reservoir would likely have to be constructed as an elevated water tower. Also, a site would have to be purchased for the northeast water tower. As the northeast area redevelops, further study is warranted to: first, determine the need for additional storage, and second, determine the costs and benefits of an elevated tank in the northeast area as compared to a ground storage tank at the current Yankee Doodle site. Several minor piping modifications and pressure zones realignments are required to increase fire flows and pressures,to serve the planned redevelopment of the Cedar Grove commercial area. Additional trunk water mains are required to serve development. These pipes are normally installed as each area develops. The largest project involves construction of a trunk water main on Cliff Road, from Lexington to Dodd Road. The purpose of this pipe is to supply the continued development of the southeastern part of the City (including the portion of Inver Grove Heights that is served by Eagan water), as well as to provide critical redundancy and looping of the portion of the system. The Safari Pass, Fairway Hills and portions of the Park Cliff neighborhoods experience low water pressures because of higher ground elevations. Many homes in these areas have installed individual booster pumps to improve pressure. In-home booster pumps are • high maintenance with a limited life and the Minnesota Department of Health discourages their use. This study has identified several alternatives to increase system pressures in these areas. Further economic analysis will determine if it is cost effective for the City to construct system facilities that would allow the in-home booster pumps to be disconnected. Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • th • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — PARKS & RECREATION Purpose of Section in the Comprehensive Plan The purpose of the Parks and Recreation Section of the Comprehensive Guide Plan is to outline a strategy for provision of recreation spaces, facilities and programs so as to encourage positive resident interaction, provide a sense of community and support economic development of the community. Status of Work to Date The 20/20 Vision, completed in early 2006, provides much of the information needed to update this section. A subcommittee of the Parks Commission has been established to review and incorporate applicable information from the 20/20 Vision into the Comprehensive Guide Plan update. Staff is working to update individual park plans presented in the 1994 Park System Plan to reflect work done to date. The Patrick Eagan Park Master Plan, currently underway, will provide a set of criteria and scoring mechanism for determining the value of potential land acquisitions. The Parks Commission has also been advised by the City Council to continue researching and discussing • potential sources of funds for future land acquisitions and park improvements. Examples of Emerging Issues and Trends 0 • New sources of funding for land acquisitions and park improvements will need to be secured as payments to the Park Site Fund diminish. • The City will need to weigh the value of the land as open or park space in relation to other potential uses as undeveloped land continues to become scarce in Eagan. • Programs and facility uses may need to shift in order to meet the changing demographics and social trends in the community. • Written partnership agreements with community user organizations need to be established and periodically reviewed in order to appropriately allocate City resources. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Comprehensive Guide Plan 2008 Update Executive Summary Plan Section – NATURAL RESOURCES (WATER QUALITY) Purpose of Section in the Comprehensive Plan The purpose of the Water Quality Section of the Natural Resources Element of the Comprehensive Guide Plan is to: 1) provide for adequate protection, preservation and enhancement of water bodies, wetlands, ground water recharge areas and wildlife habitat; 2) control runoff and erosion to prevent negative impacts to the City's water quality, plant communities and natural habitat; and 3) ensure the quality of lakes, wetlands, and streams meets or exceeds regional, state, and federal requirements and community expectations. Status of Work to Date Much has been accomplished since the City of Eagan adopted its first Water Quality Management Plan (WQMP) in 1990. In 1996, the U.S. Environmental Protection Agency recognized Eagan's program as tops in the nation. Despite a 40 -percent increase in population since 1990, water quality in the top seven recreational lakes has stayed the same or improved. In a 2005 scientific survey of City residents, 99 percent said good water quality was very or somewhat important: 0 Despite our successes, some lakes will not meet new water quality standards mandated by state and federal regulations. To stay on top, the City must be able to evaluate, include, and adapt to changing • regional, state, and federal directives for urban stormwater and wetlands management, in addition to public expectations. A major challenge is to cavy out a "state of the art" water quality program—in a nearly fully developed community with existing storm drainage infrastructure—in a cost-effective way, while acknowledging ever increasing demands for limited financial resources. In 2005, to help meet these challenges, .the City Council retained the consulting firm of Bonestroo, Rosene, Anderlik & Assoc. to prepare an upgraded Water Quality Management.Plan (WQMP) and also established a 13 -member Water Quality Task Force to guide development of the WQMP. The objectives of this work were to build on the successes of the 1990 WQMP; to consolidate and incorporate relevant policies, plans, and programs instituted since 1990; and to position the City to address efficiently and effectively the issues and needs of its surface water resources for the next 15 years. On October 17, 2006, the City Council will be presented a draft WQMP for acceptance and authorization of a 2 -month public review from October 18 to December 18, 2006. A Public open house has been scheduled for November 13, 2006, from 5:00 to 7:00 p.m. in the Eagan Room. A Public Hearing is anticipated to be set for February 6, 2007, specifically addressing wetland management strategies within the WQMP with a formal decision to adopt or modify the WQMP expected at the close of the hearing. Examples of Emerging Issues and Trends _ • Compliance with evolving federal and state water quality and stormwater requirements (i.e., stormwater pollution prevention, non -degradation, Impaired Waters/Total Maximum Daily Loads) • Development of policies/regulations for new and re -development activities regarding impervious surfaces, infiltration, best management practices, etc. • • Development of individual lake management plans; associated capital improvement projects. • Other – The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Q,3 • Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — HOUSING PLAN Purpose of Section in the Comprehensive Plan The purpose of the Housing Section of the Comprehensive Guide Plan is to identify the City's vision and expectations for housing opportunities throughout the City. Well built and well maintained housing in safe, attractive neighborhoods contribute to the high quality of life in Eagan. Likewise, the provision of adequate municipal and support services and the protection and enhancement of the City's natural environment help preserve neighborhood quality and character. Status of Work to Date The Housing Section of the current Comprehensive Plan Land Use Section has been generally reviewed by the Advisory Planning Commission in a Workshop setting and the Dakota County Community Development Agency (CDA) along with Maxfield Research provided the commission with a presentation of the recently completed county -wide housing study, as it relates to Eagan. Planning staff is also working with the Met Council, Census data and other sources to identify • demographic trends that will affect Eagan over the next 10-20 years. Examples of Emerging Issues and Trends 11 • An aging population, primarily due to the Baby Boomer generation beginning to reach retirement age in the next few years, will have an impact on housing from demand to maintenance. • Life Cycle Housing (providing housing opportunities for all ages) will continue to demand attention as the largest demographic growth population being those 62 and older. • The Dakota County CDA housing study indicates that needs for senior housing and workforce housing will continue to grow over the term of this plan. The study further indicates that it will be unlikely that conventional single family detached will be affordable for these demographic groups. • Real estate forecasts, Metropolitan Council studies and the CDA study suggest that demand for various types of attached and shared maintenance housing will continue to grow. • As the housing stock ages, maintenance and preservation efforts will become increasingly important to discourage deterioration and ensure protection of residential land values., • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. Qf Comprehensive Guide Plan 2008 Update Executive Summary Plan Section — ECONOMC DEVELOPMENT Purpose of Section in the Comprehensive Plan The purpose of the Economic Development Section of the Comprehensive Guide Plan is to define the City's expectations and strategy to encourage the continued investment and reinvestment in businesses, property and fixed assets in ways that will bring about the creation of permanent, high quality jobs and support a strong, diverse tax base within the community. Status of Work to Date In 2006, the Economic Development Commission was disbanded and work related to economic development activities and policies was assigned to the Economic Development Authority. As a consequence, a preliminary update of the Economic Development Section of the 2000 Comprehensive Guide Plan has not been completed to date. It is anticipated that the EDA would be asked in early 2007 to define a process by which it would facilitate an update of the plan for consideration with the remainder of the Comprehensive Plan. Alternatives for such a process include a formal study, a facilitated EDA review of the current Plan Section, survey input or other alternatives that may be deemed appropriate at that time. Jon Hohenstein will work with the EDA to coordinate the review at that time. Examples of Emerging Issues and Trends • • Expanding influence of information technologies in all types of businesses. The importance of high quality, redundant, high speed internet services to businesses will be key to meeting those needs. • As commercial industrial build out occurs and existing facilities age, the need to reuse, revitalize or redevelop certain properties will become increasingly important to meet continued demand for business expansion and location within the community. • Eagan has benefited by diversity in its business community and has been buffered from economic cycles for that reason. The City will benefit by continuing to position itself to support diversity in the future. • Continued importance of transportation industries due to the City's freeway access and proximity to the airport. • Changes in businesses and their products are leading to the increasing presence of a variety of home based businesses and possible interest in live -work land use alternatives. • Increasing interest in public financing incentives for both expansions and locations of businesses will underscore the importance of the City's Business Assistance Policies. • Other — The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. 11 • Comprehensive Guide Plan 2008 Update Executive Summary 0 Plan Section — COMMUNITY FACILITIES Purpose of Section in the Comprehensive Plan The purpose of the Community Facilities Section of the Comprehensive Guide Plan is to describe those facilities that serve the public interest and contribute to the sense of community in Eagan. These include schools, libraries, municipal facilities, museums, cultural sites and telecommunications facilities. Status of Work to Date City staff will work with the school districts, county and other agencies to provide an update of this section. In the area of telecommunications, however, significant work has occurred in recent years. The work done to date will lead to discussions of how this topic is positioned in the Comprehensive Plan Update. Specific activities have included: • Technology Task Force — Tom Garrison — The Technology Task Force, assisted by Community Technology Advisors, developed a Technology Plan'that addresses specific policies and action steps associated with the provision of high speed internet to all parts of the community. The Task Force identified a multi -layered strategy including wired and wireless technologies and goals for further investigation of their implementation. • Technology Working Group — Tom Garrison — One of the recommendations of the Task Force was the creation of an ongoing Working Group to further develop the concepts and action plans associated with the Technology Plan and other emerging issues in the high speed intemet and information technologies areas. • Draft Telecommunications Comprehensive Plan Section — Jon Hohenstein and Mike Ridley - The Council authorized the hiring of Community Technology Advisors to take the next step of drafting a prospective Comprehensive Plan Section for high speed intemet telecommunications. The draft has been reviewed and commented upon by the Working Group and will be forwarded to the APC for further review as part of the Plan Update process. • As directed by the Communications Committee of the City Council, the Tech Working Group will also be addressing policy options for Eagan to obtain "world class" Internet connectivity & speeds. Examples of Emerging Issues and Trends The availability of high quality, redundant, high speed intemet service is emerging as a key factor in economic development and quality of life with health care, government and education services moving online. Many cities are examining code requirements, so-called `open trench" opportunities and other measures to encourage technology deployment and ensure businesses and homes are wired for the future. The Communications Committee of the City Council has asked for a summary of the policy opportunities. • The convergence of technologies will make it important to define a policy that addresses • not only high speed intemet, but the relationship between the technology infrastructure and the providers of telecommunications services. • The City is beginning to make policy decisions related to its use ofthe conduit loop installed in cooperation with ISD 196. • To the extent that a Telecommunications Subsection relates to more than high speed intemet, it should reference or take into account the emerging challenges and opportunities related to cable television and local access programming, High Definition TV and Internet Protocol TV (IPTV.). • The City will need to determine the appropriate Plan section for this topic in the future. • Other - The Council may identify other trends and issues to be addressed in the course of the Comprehensive Plan update process. • is Q3 October 5, 2006 Orfleld Laboratories Inc PREPARED FOR Mr. Jason Ziemer City of Eagan 3830 Pilot Knob Road Eagan, MN 55122 Phone (651)675-5014 Fax (651)675-5012 . e-mail jziemer@cityofeagan.com PREPARED BY Elliott B.

The City of Eagan contracted week-long noise measurements before the new runway was completed, and again after the new runway began use. These measurements show some.trends through qualitative analysis which we may generalize to certain areas of Eagan. Statistical analysis somewhat supports these generalizations. . In the western part of Eagan, day-to-day levels were relatively consistent before the new runway. Now the new runway is operational, and the western part of Eagan experience higher noise levels on days where departures are routed south off runway 17/12. At the same time, northeastern Eagan is experiencing slightly lower noise levels now that the new runway is in use. This is likely due to lower use of those runways facing that area of Eagan. In general, the northeastern area of Eagan also experiences the same higher noise levels on days with southerly routed departures.

In June 2005, the City contracted Wyle Laboratories to conduct the initial measurement set before the runway opened. The new runway began use October 27, 2005.Orfieid Laboratories conducted a second measurement set in June 2006. The second measurement was executed to be similar to the first in most respects. In order to get a as true a comparison as possible, the same equipment and settings were used as in Wyle Lab's initial measurement. OVERALL COMPARISON The day -night average sound level was measured at ten locations. The averaging period was week in June of 2005, before runway 17/35 was complete, and June of 2006, after runway 17/35 was operational. Figure 1 shows the before/after comparison for each site. Locations are identified in detail in Appendix B. The day -night average, expressed LoN or DNL, is the equivalent sound level over a 24-hour day with 10 dB added to nighttime levels (from 22:00 to 07:00). This is the preferred metric of the Metropolitan Airports Commission (MAC), as well as the Federal Aviation Administration (FAA). 70 65 R 60 "q a e 55 0 50 45 o t M r N 4 40 i m 4 35 30 Ske 1 Ske 2 Site 3 Site 4 Sfte 6 Slee 6 Site 7 Site 8 Ske9 Site 10 Figure 1: LoN Comparison Orfleld Laboratories Inc Project New Runway Noise Monitor Client City of Eagan At some locations, the overall levels increased, and at other locations they decreased. One should not read too much into this direct comparison. There are many variables, other than the new runway, which may cause the change in result. Some of these factors are explored below. RUNWAY USE STATISTICS The number of over -flights will greatly impact the noise level. The Minneapolis Airports Commission keeps records of their runway use statistics, and the daily statistics are easily accessible. These data are used in this analysis, here qualitatively, and later statistically. The runway use provides an estimate of traffic over the measurement sites. Flights will differ in elevation and direction depending on weather conditions and their origin or destination. The number of overflights at a location will correlate well with runway use,. though runway use does not directly predict overflight. 2000----------------------------- ----------------------------- --------- ------------------- ---------------- '0 1500 -'- ---- -- m now ®4/22 17/35 1000 ',X,h�{ � il�6 ®12RI30L J11"i u: Iii` 4}kl{ a 12U30R v' 500 - ---- m Y4 m 0 - ---- ---- 'rs -- Week Week Week beginning beginning beginning 6/13/05 6/13/06 6/20/06 Figure 2: Runway Use over Measurement Periods The overall runway use is shown in Figure 2. The first thing to notice is runway 17/35 is handling approximately 13% of the traffic during the 2006 measurement periods. Orfleld Laboratories Inc Project New Runway Noise Monitor Client City of Eagan The next observation is there were approximately 10% more flights over the first week — before runway 17/35 was operational. This may have an effect on the noise levels — namely understating the noise levels over the 2006 measurement periods. Normalizing the measurement result to the runway traffic is one way to estimate the rough impact of this change. It would depress the 2006 overall LDN measurement by 0.5 dB, a relatively insignificant change for a week-long duration. 1000 goo 600 m u 700 ®SW z a 600 ®SE C ■S E 500 NW e a 400 NE m v 300 N a a 200 a m 100 0 12Figure 3: Direction of runway use Figure 3 shows the runway use for each runway, and the direction of the runway used. That is, departures which take off towards the south are grouped with arrivals approaching from the south. We will analyze these southern flights to estimate the over -flight traffic over Eagan. Daily flights arriving from or departing to the south are shown in Figure 4, Figure 5, and Figure 6. Runway 12L/30R and 12R/30L run parallel to each other, from the northeast to the southwest. These runways face the north end of Eagan. Runway 17/35, the new runway runs south over the western end of Eagan. The south end of runway 4/22 faces into Bloomington, and only some of the departures will turnto fly over Eagan. This runway is used very little, so the impact of these statistics will be insignificant..

Wind conditions determine the direction to land and take -off. Runway use during the first measurement period in 2006 is consistent with the period in 2005. Runway use over the second measurement period in.2006 has a much higher number of arrivals than departures. These differences are shown in Figure 7.

Arrivals will approach in-line with the runway, at a IoWer altitude, and with a lower engine speed. Departures will use a greater engine speed, and after clearing the end of the runway climb and tum as quickly as possible. The noise impact of each will depend on the location of the site, and its relation to the runway. QUALITATIVE ANALYSIS Qualitative analyses are performed in this study by examining the results and observe trends and relationships. From this examination we infer that one event may cause another event. At its essence, the qualitative analysis is a means to construct hypotheses. Graphs of data are the most useful tool to visually discover these potential trends and relationships. Appendix C contains the hourly and daily results shown in graphs. STATISTICAL ANALYSIS The daily measurements and daily runway use statistics were entered into statistical analysis software. Table 1 shows the Pearson correlation between individual measurement sites and runway use. The Pearson correlation coefficient measures linear correlation or predictability between two variables. The value of the coefficient varies between -1 and +1. A value of +1 indicates that one variable can be predicted perfectly by the other. A value of -1 means the same thing except that the variables are inversely related. A Pearson correlation of 0 indicates that neither of the two variables can be predicted from the other. by using a linear equation. ff it Project New Runway Noise Monitor s Client City of Eagan Table 1: Pearson.Correlation of Daily Noise Levels Correlation is significant at the 0.01 level (2-talled), rboid, underline] Correlation Is significant at the 0.05 level (2-tailed).

This is mainly due to the small number of cases (days) and the great variability in aircraft noise from day-to-day. In general, the correlation coefficients somewhat support the qualitative analysis at most sites. .76zldk�-]101:N]AI:Id1v1I11L1f PYt*� r_111UW&i &9Yll=111i The Site 1 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway'17/35 in 2006, which were not present in the 2005 measurement. A qualitative analysis of the daily and hourly noise levels show the behavior of noise at Site 1 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways. This position is approximately 4 % miles south -by -southeast of runway 17/35. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased noise levels in L,q, LDN, L1o, and Lot. The statistical analysis generally supports the qualitative analysis. Noise levels at Site 1 correlates very poorly with all runway use, except for runway 17/35. It shows some correlation between departures off the south end of runway 17/35, though the correlation is not statistically significant. ANALYSIS AT SITE 2 The Site 2 day -night average level over the 2006 measurement period decreased overall from the 2005 measurement. This is due to a decrease in the nighttime hourly average levels (I -Q. There is no clear explanation for the nighttime measurements. The daytime average levels did increase from the 2005 measurement to the 2006 measurement. A qualitative analysis shows that, over the 2006 measurement, the Leq LDN, LSO, 1-90, and Les measurements were higher on days with heavier departures. However, 1-10 and Lot are much higher than 1-50 at other sites on these days. The difference between 1-10 and L50 is smaller at this site on the departure -heavy days. This may be due to departures, this far from the airport, are high enough in elevation that they can be heard over, a longer duration. The engine noise builds slowly and dies slowly, rather than getting a shorter blast of engine noise. This position is approximately 51/2 miles south -by -southeast of runway 17/35. On days with heavier arrivals, L10 and Lot are much higher than at this site. This may be due to arrivals, at their lower elevation, exposing this site to shorter durations of their engine noise. The engine usually runs lower at arrivals, so the overall noise dropped on these days. Most sites are within a mile of a either Highway 77 or Interstate 35E (excepting Site 5, Site 6, and Site 9). This site is approximately a half -mile from both highways, one on either side. This may also contribute to the noise, as it does at other sites. Rush hour traffic is reflected in the statistical measurements as well. Project New Runway Noise Monitor 0 Client City of Eagan Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures, are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is consistent between sites 2, 3, 8, 9, and 10. The departures off 17/35 are somewhat correlated with higher noise levels at Site 2. Interestingly, lower noise levels are correlated with arrivals onto 17/35 with statistical significance. ANALYSIS AT SITE 3 The Site 3 day -night average level over the 2006 measurement period did not differ much overall from the 2005 measurement. The daily and hourly noise levels show the behavior of noise at Site 3 is somewhat consistent with the noise at other nearby sites. This position is approximately 5 miles south -by - southeast of runway 17/35. A qualitative analysis shows that, during the 2005 measurement period, the daily average noise levels (LON) varied little, except nighttime levels were responsible for higher LoN some days. The statistical metrics (L„) while varying hour -to -hour, exhibited similar behaviors day-to-day. During the 2006 measurements, the daily Laq, LpN, L,o, and Loi results seemed to increase on days where runway 17/35 was mainly used for departures. The meter did not measure a full Day with heavy departures over Eagan. This was due to an overnight meter malfunction. Perhaps if the departure -heavy days been measured in full, the overall results would have been higher at this location. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is consistent between sites 2, 3, 8, 9, and 10. There is a statistically significant correlation between noise levels and the number of flight departures on runway 17/35: At Site 3, like site 2, arrivals off the 17/35 runway are correlated with higher noise levels, but without statistical significance. ANALYSIS AT SITE 4 The Site 4 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The behavior of noise at this site, however, is inconsistent with the noise at other nearby sites, nor consistent with its relation to the airport runways. This position is approximately 6'/ miles south - by -southeast of runway 17/35. This monitor location overlooked a busy city street. Most of the noise was road traffic, as evidenced by the traffic cycles, especially in the Lso measurement. It was more pronounced in the 2006 measurement than the 2005 measurement. Noise levels were consistent day-to-day (a little lower over the weekends), whereas most other sites exhibited different noise characteristics depending on the number of arrivals versus departures over Eagan. V In Wield Laboratories Inc , N , Project New Runway Noise Monitor Client City of Eagan Statistical analysis shows correlations which do not represent the probable overflight noise. This may be due to the fact that the flight arrivals over Eagan heavily outnumbered departures during the 2006 measurement, which was also, in general, higher in noise level. The data from this site was heavily influenced by the traffic noise. ANALYSIS AT SITE 5 The Site 5 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. Despite this, the behavior of noise at Site 5 is inconsistent with expatiations and the noise at other nearby sites. Note that the normal diurnal cycle disappears after June 21, 2006. Usually every metric drops through the small hours of the morning. This daily cycle can be observed on the hourly percentile level graphs. At Site 5, the 1-01 and Lto measurements remain relatively constant. This is likely due to a babbling brook in the neighbor's back yard that ran down the hill. The brook was still under construction Tuesday and Wednesday. The construction may account for much of the high daytime levels. The brook was running constantly since Wednesday, and the sound levels never dropped much below 45 dB at the monitoring station. This position is approximately 6'Y2 miles southeast of runway 17/35. The 41 measurement may reflect a higher number of departures than arrivals over Eagan, but it is not significant. Statistical analysis showed correlations which were similar to Site 4, but not to other sites. There is probably a similar reason for this: the noise levels were generally higher during the 2006 measurement, and the number of arrivals greatly outnumbered the number of departures during the same period. ANALYSIS AT SITE 6 The Site 6 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway 17/35 in 2006, which were not present in the 2005 measurement. This position is approximately 6'/2 miles southeast of runway 17/35. Qualitative analysis shows that, despite being further away, the behavior of noise at Site 1 is consistent with closer sites and consistent with its relation to the airport runways. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased daily and hourly noise levels in L,q, LDN, L10, and Lot. The statistical analysis generally supports the qualitative analysis. Noise levels at Site 1 correlates very poorly with all runway use, except for runway 17/35. It shows statistically significant correlation between noise levels and departures off the south end of runway 17/35. 0 Project New Runway Noise Monitor Client City of Eagan ANALYSIS AT SITE 7 The Site 7 day -night average level over the 2006 measurement period increased overall from the 2005 measurement. The overall increase is expected, due to flights from runway 17/35 in 2006, which were not present in the 2005 measurement. Qualitative analysis of the daily and hourly noise levels show the behavior of noise at Site 7 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways, This position is approximately 5 miles southeast of runway 17/35. During the 2006 measurement period, days where runway 17/35 was mainly used for departures also showed increased noise levels in Lq, LDN, 1-11), and Lol. Site 7 was located on top of a hill, without any nearby trees or structures. Without anything to break up the sound of overflights, this site had higher results than the other sites. Overflight noise would be recorded from further away, and the ground effect will also moderately increase the noise. Traffic noise probably also influenced both the 2005 and 2006 measurements at Site 7. Statistical analysis is contrary to the qualitative analysis. Reasons for this are not immediately apparent. For answers, this may require additional research, testing, or analysis. ANALYSIS AT SITE 8 The Site 8 day -night average level over the 2006 measurement period decreased overall from the 2005 measurement. In part, this is due to a decrease in the nighttime hourly average levels (L,q). Also, for days with a light number of departing flights, the daytime level was lower in 2006 than it was in the 2005 measurement period. There is no clear explanation for the nighttime measurements, nor the decrease in levels on particular days. During the 2006 measurement period, behavior of noise at Site 8 is consistent with the noise at other nearby sites, and consistent with its relation to the airport runways. This position is approximately 4 miles southeast of runway 17/35. Days where runway 17/35 was mainly used for departures the daily and hourly noise levels also showed increased noise levels in L,q, LDN, L,o, and Lot. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use, except for runway 17/35. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. This is also consistent between sites 2, 3, 8, 9, and 10. The departures off 17/35 are somewhat correlated with higher noise levels at Site 8. Interestingly, lower noise levels are correlated with arrivals onto 17/35 with. statistical significance. Project New Runway Noise Monitor Client City of Eagan ANALYSIS AT SITE 9 The Site 9 day-night average level over the 2006 measurement period decreased overall from the 2005 measurement. The overall decrease is expected, due to fewer flights over Eagan from runways 12U30R and 12R/30L in the 2006 measurement, which were diverted to runway 17/35. The daily and hourly noise levels show the behavior of noise this site is consistent with the noise at the nearby Site 10, and consistent with its relation to the airport runways. This position is approximately 5 miles southeast of runway 12R/30L. Sites 9 and 10 are closer to the 12U30R and 12R/30L runways than to the 17/35 runway. During both the 2005 measurement period and the 2006 measurement period, days where runways were mainly used for departures over Eagan also showed increased noise levels in L q, LDN, L,o, and Lot. In general, all metrics Site 9 were lower in 2006 than they were in the 2005 measurement. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. There is Tittle correlation with runway 17/35 at this site. That is reasonable, since Site 9 and 10 are located under the flight path of the 12/30 runways. ANALYSIS AT SITE 10 The Site 10 day-night average level over the 2006 measurement period decreased overall from the 2005 measurement. The overall decrease is expected, due to fewer flights over Eagan from runways 12U30R and 12R/30L in the 2006 measurement, which were diverted to runway 17/35. The daily and hourly noise levels show the behavior of noise this site is consistent with the noise at the nearby Site 9, and consistent with its relation to the airport runways. This position is approximately 2'% miles southeast of runway 12R/30L. Sites 9 and 10 are closer to the 12U30R and 12R/30L runways than to the 17/35 runway. During both the 2005 measurement period and the 2006 measurement period, days where runways were mainly used for departures over Eagan also showed increased noise levels in Lq, LDN, L,o, and Lor. In general, most metrics at Site 10 were similar in 2006 than they were in the 2005 measurement. Statistical analysis generally supports the qualitative analysis. There is relatively poor correlation of the daily noise levels and the runway use. Though the correlation is poor, it is consistent in that departures are slightly correlated with higher noise levels and arrivals are slightly correlated with lower noise levels. There is little correlation with runway 17/35 at this site. That is reasonable, since Site 9 and 10 are located under the flight path of the 12/30 runways. 1 Orfleld Laboratories Inc 0 Project New Runway Noise Monitor Client City of Eagan CONCLUSION In general, the new runway 17/35 does seem to have an impact on noise levels in the City of Eagan. Since the overall number of flights during the measurement periods were less after the new runway became operational, there is not a direct comparison between the "before" and "after condition on a city-wide basis. Certainly, the impact is dependant on location, and the direction of arriving and departing flights. The City of Eagan should continue to monitor aircraft noise levels. )field Laboratories Inc • , A N D Project I New Runway Noise Monitor Client City of Eagan.
