ADJOURNMENT MEMO TO: ADVISORY PARKS RECREATION COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: APRIL 30, 1984 RE: MAY 3, 1984 COMMISSION MEETING Following the Commission's approval of the agenda and the minutes of April 5, there are two items from the April 5, 1984 Commission meeting concerning development proposals for the Commission to deal with. The first of these items relates to Lexington Place South. Members will recall that the developer is proposing to install a "private park" within the residential development. In doing so, the developer is seeking a credit towards the park dedication requirements of the City. Enclosed in the packet is a separate memorandum prepared for the Commission which provides additional information regarding this item. Also deferred from the April meeting was a preliminary plat for Peace Reform Church. Members will recall that the plat provided for outloting of a portion of the land parcel for future development, and for construction of the church proper on the remaining portion of the parcel. The question before the Advisory Parks and Recreation Commission was whether to obtain a dedication requirement for this preliminary plat. The department staff has contacted other communities relative to their requirements on church property and will present that report at the May meeting. The third item under "Development Proposals" is the Pheasant Knoll Townhouse preliminary plat as proposed by Dunn Real Estate Mgmt. Inc.. Members may recall a similarly entitled preliminary plat prepared by Mr. Will Stenzel. Mr. Stenzel is not involved in this project and a different concept is being proposed, although the preliminary plat retains the same name. A separate memo has been prepared by the Director of Parks and Recreation referencing this project and is included in the packet along with the Planner's Report. A careful reading of this memo and Planner's Report is requested. Residents from the Heine Strasse Addition are expected to be in attendance at this meeting. Members may want to visit the site prior to the meeting to become familiar with the area under discussion. The fourth item for the Advisory Commission is the Cinnamon Ridge 7th Addition. Can American Realty Corporation is proposing to purchase the remaining parcels within the Cinnamon Ridge P.U.D. on which they will construct 230 apartment units. The Planned Unit Development Agreement has previously provided for a land dedication with applied credits towards the cash dedication requirement for these apartment units. Commission members will also note the Director of Parks and Recreation's memo to the City Planning Director regarding the fact that the original developer, "Zachman Homes has not complied with previous park dedication requirements within the P.U.D.. The last item under "Development Proposals" is a preliminary plat by Sienna Corporation for Birch Park Addition. This addition is a proposed redrawing of the Windcrest Addition in which a land dedication has been previously identified and received. This item is being presented to the Advisory Commission for informational purposes. There are no identified items under "Old Business" for Commission action during the month of May. However, under "New Business" is an old item relative to a trail connection between Heine Strasse and Clemson Court. Please refer to the packet which includes a memo and letter relative to the issue of a bituminous trailway from Heine Strasse to Clemson Court. The first item under "Other Business and Reports" will be the designation of Commission members to staff the informational meet- ings scheduled for May 5, 9 10. Members will recall that these informational meetings are to be hosted by the Advisory Parks and Recreation Commission and it would be appropriate to have at least one, if not two, members of the Commission in attendance on those dates. A request has been received from the Eagan Athletic Association for storage space of their various recreational program equipment. The Association has formerly been keeping their equipment in the Cedarvale Building, but because of expansion of the Nautilus Center, they will be losing their storage space and be required to move. The third and final item for discussion by the Advisory Commission is relative to How Best To Handle A Successful Bond Referendum And The Utilization Of Consulting Services. The Director of Parks and Recreation would like to have an information discussion with the Advisory Commission on how best to proceed, assuming the Parks Bond Referendum is successful. Items should be discussed and directions expressed as how best to utilize consulting services, contracting, time lines and other aspects relative to the development of the park system with the bond money. Also included in this month's packet are two articles that I hap- pened to run across of some interests to the Advisory Commission. As always, should members of the Advisory Commission be unable to attend the scheduled meeting, notification to the office would be appreciated. Respe submitted, A regular meeting of the Advisory Parks Recreation Commission was called to order by Chairman Martin at 7:45 when a quorem was present. Members present were Martin, Thurston, Alt, Kubik, Masin and Bertz. Members absent were Carroll, Jackson, Ketcham and McNeely. Also present were the Director of Parks Recreation, Ken Vraa; Administrative Assistant, Liz Witt; and Parks Recreation Intern, Jim Sturm. Bob Hoffman, legal 'counsel for Orrin Thompson Homes, was present to discuss Lexington Place South. Commission member Ma,sin moved, Alt seconded to approve the agenda as presented. The motion carried. A. Lexington Place South MINUTES OF A REGULAR MEETING OF THE ADVISORY PARKS AND RECREATION COMMISSION EAGAN, MINNESOTA APRIL 5, 1984 AGENDA MINUTES February 2, 1984 Two typographical errors were noted in the February 2nd minutes. On a motion by Alt, seconded by Bertz, the minutes were approved as corrected. March 1, 1984 Under Other Business, item D. Recreation Committee, the following change was made: "The committee felt that any increase in recreational activities would require additional staff." Commission member Kubik moved, Bertz seconded, to approve the minutes as corrected. The motion carried. DEVELOPMENT PROPOSALS Bob Hoffman of Larkin, Daly and Hoffman Law Firm and representing Orrin Thompson Developers, presented the Lexington Place South proposal. Mr. Hoffman explained that the developers were proposing to rezone 50 acres from R4 to R1. There would be 134 units with zero lot lines. The developers are proposing that a 5.4 acre outlot be utilized as a private recreation facility. Under consideration is a swimming pool /spa, a recreation building, tennis courts and a ponding area. Mr. Hoffman explained that this is a marketing approach to appeal to home buyers. He stated that a mandatory home owner association would control the park. Mr. Hoffman went on to explain other elements of the proposal and additional background. Mr. Hoffman then posed three questions: 1. Can private park receive park credit? 2. Does the proposed facility satisfy the needs for the 134 units? 3. How much would the cash dedication be? SUBJECT TO APPROVAL Chairman Martin observed that a swimming pool does not fit with facilities available to the general public. Tennis courts would serve to lessen the demand on City tennis courts so consideration might be given for credit ADVISORY PARKS RECREATION COMMISSION MINUTES April 5, 1984 Page 2 for these. He did remind the commission that the Berkshire Pond proposal requested credit for a park and it was denied. Commission member Thurston expressed concern with setting a precedent. If private parks are allowable then every developer would be requesting the same consideration. It was pointed out that the private park would not meet other park needs of the residents, such as ballfield space. Parks Recreation Director Vraa said if credit is determined to be given, the City should make it known that there would be no credit for a swimming pool thus setting precedence for not allowing credit for certain amenities. He reminded the commission that action was not necessary that evening if they felt they did not have sufficient information. Commission member Bertz stated that the City should be very careful that the wording in the developer's agreement and homeowner association is such that the City's interests are safeguarded. She did not want a loophole to occur which would serve to give every tot lot in town park credit. Commission member Kubik agreed. He said the City must be careful that we don't lose our bargaining power of future park dedications. There was discussion as to if other communities had been approached with similar proposals, how much of the park is to be used for ponding, etc. Commission member Masin moved, Kubik seconded, to table the item to the May 3rd agenda requesting staff to prepare a memo in response to the questions that had been raised. The motion carried. B. Wescott Hills Revised Director Vraa noted for the commission that the developers believed the park dedication was paid previously. He said he reviewed the files, found nothing and felt it was incumbent upon the developer to prove payment. On a motion by Martin, seconded by Kubik, the commission approved the recommen— dation to require a cash dedication. C. Brittany 7th Addition Parks Recreation Director Vraa explained that this was another part of the Tollefson Planned Development consisting of single family homes in Section 33. Brittany 7th is 30 acres and has 50 units. Director Vraa noted that the 30 acres are part of 110 acres presently owned by Mr. J.D. Brown. The City would like to have a neighborhood park in the northern part of the 110 acres but such a park might be difficult to obtain with parcels sold on a piecemeal basis. Chairman Martin moved, seconded by Bertz, that the City accept cash dedication. They further recommended that discussion be initiated with Mr. Brown about siting a park parcel on his acreage adjacent to the Walden Heights park parcel. He then could sell the remainder of his property with the park dedication already fulfilled. The motion carried unanimously. ADVISORY PARKS RECREATION COMMISSION MINUTES April 5, 1984 Page 3 D. Cedar Cliff Commercial Director Vraa noted for the Commission that park dedication was still forthcoming on this parcel. Commission member Alt moved, Masin seconded, the cash dedication at the commercial industrial rate be accepted and that there should be an 8' trail along Nicols Rd. and Cliff Rd. The motion carried unanimously. E. Peace Reformed Church Director Vraa said the issue is whether to collect a park dedication requirement from a church platted parcel. Commission member Kubik moved, Thurston seconded, that action be deferred on this proposal until a policy for park dedication from a church and other public entities be researched and developed. The motion carried. F. Group W Group W Cable Company proposes to place a headend facility on a 1.8 parcel near old Highway 13 and old Sibley Highway. Commission member Thurston moved, Bertz seconded, to accept cash dedication at the commercial industrial rate. The motion carried. A. Parks Bond Referendum Director Vraa announced that a special edition of the newsletter will be distributed with the Eagan Chronicle on Sunday, April 15. The parks referendum task force will meet Monday, April 9, to identify tasks which should be carried out. Assignments to promote approval of the referendum will be made e.g., get athletic or home associations to distribute flyers a few days before the referendum. Director Vraa informed commission members of the informational meeting scheduled in May. He also commented that presentations will be made at meetings of the fire and police departments. A. Tree Nursery OLD BUSINESS NEW BUSINESS The Director of Parks Recreation referenced the packet information concerning the tree nursery. Vraa said that $7,000 is budgeted in 1984 for the reforesta— tion program. Nursery stock could be planted on a staggered basis to insure there will be trees for years to come. Director Vraa said it might be possible to utilize persons assigned by court services to perform a community service to do some cultivating. The Parks Department staff would do all the pruning. Commission member Kubik asked if we could join with other communities in a tree nursery program or if distance would be a problem. Director Vraa said he is looking for an accessible spot with water available. Chairman Martin suggested the senior citizens be contacted to see if they are interested in caring for the trees. The consensus of the commission was favorable to having a tree nursery. Director Vraa will review sites and report back to the commission. ADVISORY PARKS RECREATION MINUTES April 5, 1984 Page 4 B. Boat Ordinance A copy of the draft ordinance regulating boating and related water activities within the City, was distributed with the packet. Commission members reviewed the draft and expressed some concern as to enforcement as it related to docks. After review, the Commission expressed approval. A. Heine Pond Park B. River Hills Park Equipment OTHER BUSINESS Director Vraa informed the Commission that the developer is reviewing the possibility of putting in a roadway on park property to be shared with multiple housing units on the east. The item will appear on the May agenda. A request has been received for matching monies to repair /replace play equipment in the River Hill park area. The Commission deferred action on the request until after the referendum. C. District #196 The School District put forth a similar request to River Hills. They are proposing to repair /replace play equipment at Northview School. Director Vraa said that he had offered department assistance, but that the District would have to show how the public could utilize the equipment before any financial assistance could be sought. He said the City could help lay out the play area in lieu of money. Director Vraa will keep the commission advised as to any further contact with the School District. D. Hiring of Roger Sjobeck Director Vraa told the Commission that the City Council has approved the hiring of Roger Sjobeck to review proposals for the Kehne House. Commission member Kubik moved, Martin seconded that the meeting be adjourned. Time of adjournment was 10:05. Dated: ADJOURNMENT Advisory Parks Recreation Secretary LW MEMO TO: ADVISORY PARKS RECREATION COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: APRIL 13, 1984 RE: LEXINGTON PLACE SO. BACKGROUND: At the April meeting of the Commission Mr. Robert Hoffman, repre- senting U.S. Homes Corp., presented a preliminary plat for Lexington Place South. Mr. Hoffman indicated that Orrin Thompson /U.S. Homes was proposing to develop a 52 acre ponding and open space area with- in the single family residential homes as a "private park He had suggested that the construction of tennis courts, play equipment and a possible swimming pool were expected. Mr. Hoffman requested that the Advisory Parks and Recreation Commission consider a credit towards the park's dedication requirements with the installation of these facilities within this private park area. ADDITIONAL INFORMATION: Mr. Bill Allen of Orrin Thompson Homes has indicated that the pri- vate park concept is a marketing approach to attract homebuyers within this development. The approach is to build facilities that are generally lacking in a residential development area and provide opportunities for people who may have little to do or are looking for things to do in their free time. This concept has been used for many years within a multiple dwelling complex. Mr. Allen indicated that although the park plan is still conceptual, Orrin Thompson Homes is contemplating providing a pool /spa with a smaller and somewhat less elaborate facility than that which is being developed for the Lexington Place condominium area. He indi- cated that tennis courts are anticipated and that play equipment is being considered, but both are dependent upon the type of buyers attracted to the area and their specific needs. Mr. Allen stated that preference by the City for play equipment would play a role in the decision as well. The facilities provided within the private park area would be con- trolled through a Homeowner's Association. This mandatory associa- tion would establish its own Board of Directors to control the pri- vate park area. Mr. Allen estimated that the first year's cost for operation of the park would be absorbed by Orrin Thompson Homes. He expected that annual dues would be $5 or less per month with the proviso that there could not be greater than a 10% increase in annual dues unless voted upon by a majority of the homeowners within the association. LEXINGTON PLACE SO PAGE TWO APRIL 13, 1984 Although grading and ponding plans are not yet completed, Mr. Allen anticipated that approximately 22 acres of the 5 acre site would be devoted to the private park area. He has indicated that in con- junction with these park facilities in other communities with mul- tiple dwellings, the size of the parks have ranged from two (2) up to five (5) acres in size. Mr. Allen will be present at the May 3 meeting of the Advisory Parks and Recreation Commission to provide further details concerning the private park concept. DISCUSSION /ALTERNATIVES: The Advisory Commission has to consider whether it wishes to provide a credit against the City's cash dedication requirement for this residential development based upon the developer providing these private facilities. It appears that there are only two alternatives to be considered either approve of some type of dedication credit or determine that no credit should be extended. Because the park is relatively small in size, it obviously cannot provide for all of the needs that the homeowners will require of a park system. An example is open ball field space, winter activi- ties or other anticipated or expected park facilities within the system. Because of this, it is logical to conclude that no parks dedication credit should be extended. If, however, the Commission determines that the private tennis court facilities, play equipment or other amenities may indeed lessen the impact upon the park system, then it may find that credit should be extended towards the dedication. If this were the case, the Commission should then decide to what extent credit might be extend- ed. With approximately 135 single family units being proposed for the development, it is probable that the population in the develop- ment will range in size from 275 to approximately 325. The developer is currently proposing a similar type arrangement to the City of Rosemount. As of this writing, no determination has been made by this community, although it does not appear that Rosemount will extend credit to the developer for the private park arrangement. COMMENTS: It is interesting to note that the developer is proposing to privde a developed park as an inducement to residential homeowners. This tends to reinforce the perception that developed parks are important to people to such a degree that a developer is willing to invest a substantial amount of money to provide these park amenities at a pace faster than the City in an efort to attract home buyers. LEXINGTON PLACE SO. PAGE THREE APRIL 13, 1984 The City might have some concerns for the long -term prospects for this park remaining as a private facility. Is it not possible that the park, at some time in the future, be turned over to the City? If this is a possibility, is that seen as a positive or negative impact on the park system? To help answer this question, I will relate the following two (2) experiences with neighboring communities: ACTION TO BE CONSIDERED: The Advisory Parks Recreation Commission should determine that there shall be no credit against the City's park dedication policy for this private park or that the City shall extend a credit toward the City's cash dedication requirement for the single family homes and determine an amount. KV /js A facility was built in the City of Apple Valley several years ago in which Homeowners Association participation was voluntary. The swimming pool complex and Community Center built by the developer was ultimately turned over to the City. The City has undertaken the project and oper- ates it for the benefit of the community. However, because the facility is somewhat smaller than would normally be designed as a community facility, it does not now get nor facilitate as effectively the various programs that would normally be offered. A second experience with the City of Lakeville under the offices of a different developer included two (2) small backyard type pools within residential areas. Here too, the volunteer Homeowners Association ultimately turned them over to the community for operation. After two (2) to three (3) years of a struggle to refurbish the pools, the financial drain of repair, operating and maintaining became so excessive that the pools were ultimately closed down and torn out. MEMO TO: ADVISORY PARKS RECREATION COMMISSION V i j FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: MAY 3, 1984 RE: PROPOSED PRELIMINARY PLAT PHEASANT KNOLL The cover memo included with the packet for the May 3 Advisory Commission meeting referred to a separate memo relative to this plat. This memo was not completed as anticipated and was not included in the packet. Following herewith is the information regarding this proposed development. BACKGROUND: The Advisory Parks and Recreation Commission has previously looked at the preliminary plat entitled Pheasant Knoll. This first plat was proposed by Mr. Will Stenzel. Mr. Stenzel is not involved in this new project and a different concept is being proposed, although the site and plat retain the same name. The original application submitted was for a townhouse development consist- ing of approximately 120 units. This project will consist of 80 townhouse units with access to 66 of the units from Thomas Lake Road. The remaining 14 units are to receive access from County Road 30. The entire site consists of 18.7 acres and is part of the Blackhawk Park Planned Unit Development. Within this development agreement, the City was to receive park land of approximately 10 acres. This 10 acres is dominated by Heine Pond. Members will recall that at one time the Commission was concerned about accepting this park land dedication because of its apparent lack of value to the park system. However, within the Park System Study, the Systems Plan Consultant was directed to review the suitability and useability of this ponding area for parks purposes. His report was summarized with a concept sketch which indicated that a roadway off of County Road 30 with a parking area and boat launch could be accomplished making the site useable. It was also suggested that in order to accomplish this, additional land acquisition beyond that which was shown in the Black hawk P.U.D. would be necessary. This additional acquisition consists of approximately one acre and was made necessary by the then projected high water elevation. Under the previous proposal by Will Stenzel, the City would have received this additional one acre to accomplish what was then shown in the concept sketch as a gift. THIS PROPOSAL: The new preliminary plat for Pheasant Knoll provides access to 14 residen- tial units off of the same roadway access to be utilized by park facil- ities. Members will notice by the concept plan that a cul -de -sac is pro- posed with a parking area from this roadway for parks purposes. This parking area would also provide access to the lake via a boat launch. The proposed cul -de -sac is proposed to be a public road. ISSUES CONCERNS: There are several issues and concerns which have been raised during the review process. Relative to drainage, storm waters collected off of the proposed cul -de -sac would be diverted by a storm sewer into a ponding area north of County Road 30. This would help preserve the water quality within Heine Pond. A second issue of concern is relative to the safety for vehicles access from County Road 30 to the cul -de -sac. The Dakota County Highway Dept. has approved the location of the cul -de -sac access from County Road 30 as meeting its distance /intersection requirements. In addition, the developer has also agreed to provide sufficient space for a right hand turn lane off of County Road 30. A third issue has been raised regarding the amount of park land dedication to be received. Under this proposal, the City would receive approximately 9.25 acres. This is approximately three quarters less park land than was conceptually shown previously. However, as has been the case in other P.U.D.'s, adjustments to this acreage amount has been determined to be acceptable. Any shortages of park land at one particular park will be required to be made up elsewhere within the P.U.D.. A fourth concern expressed by residents was relative to the usage of Heine Pond for parks purposes. Apparently there was an expression that the development of the park facility, as they envisioned, would create high boat traffic, water skiing, congestion, parking problems, etc.. The Parks System Plan has previously identified Heine Pond for possible use in fishing, swimming and canoeing. (Please refer to the Ponds and Lakes Section of the Systems Plan Study, pages D1 D17). The Systems Plan Study, Lake Management Summary on page D17, indicates that Heine Pond is suitable for permanent fishing with access needs of a ramp, fishing dock and four spaces for parking. Restrictions would include rib gas motors on the lake, although electric motors would be permitted. Winter restrictions included no vehicles or overnight fish houses. Because of this joint usage the cul -de -sac with adjacent residents, it may also be desirable to include a "no parking" provision along the roadway to restrict overnight parking and possible congestion of the lake. Further, it would be well to insure that the final design of the parking lot and boat launch area address congestion and a specific closing hour for the park facility. Other park regulations governing its use should also be posted. The Director of Parks and Recreation still has a concern relative to the high water elevation for Heine Pond. The normal water elevation is shown at 873.5 which provides a stable and suitable lake surface. However, there is a degree of uncertainty as to what is the high water elevation and what the impact would be upon the park area. Members may recall that at the time of the Systems Plan Study and the development of the concept sketch, there were numerous remarks regarding the fact that the high water elevation shown by the Systems Plan Consultant appeared to be too high and inaccurate. Staff has asked the engineering firm associated with the development to work closely with the City's Consulting Engineer to determine what that high water elevation is. This is still being researched and computations extended to derive a high water elevation mark. A very recent visit to the site has raised yet another concern. This concern is relative to the size and proximity of the proposed cul -de -sac. While this cul -de -sac meets the City's design criteria, the concern is relative to the closeness of this cul -de -sac to the water's edge. It is this writer's opinion that this cul -de -sac should be reduced and /or pulled back from the waters edge to increase the green space and improve the aesthetics of the area. Alternative measures which would seek to reduce the size by either offsetting the cul -de -sac, reducing the radius or a different design should be reviewed in greater detail. Another issue closely related to the cul -de -sac is the size of this public road. To meet City engineering design standards, this roadway width is required to be 32'. As a park road, it was conceived that this roadway would be of a lesser dimension, thus reducing the amount of asphalt while increasing the amount of green space. This is also important as a cost item. This is significant to the City and particularly the Parks and Recreation Department as the developer has not acknowledged the ability to pay for this entire road and appears willing only to assume those costs for road constructions beyond the access provided for the park's parking lot. The last remaining issue for the Advisory Commission to consider is rela- tive to the importance of a trail connection from the proposed cul -de -sac to Thomas Lake Road. The developer has already agreed to provide a 10' wide trail easement along County Road 30 for future trailway construction. COMMISSION'S ACTION: It will be necessary for the Advisory Parks and Recreation Commission to sort through the various issues raised by this memo as well as other issues that it feels are important in its fact finding and recommendation to the City Council. KV /js cc: Tom Hedges City Administrator SUBJECT: APPLICANT: DUNN REAL ESTATE MANAGEMENT, INC. EDMUND B. DUNN OUTLOT A, THOMAS LAKE HEIGHTS' EXISTING ZONING R -3 UNDER THE BLACKHAWK PARK PLANNED DEVELOPMENT DATE OP PUBLIC HEARING: APRIL 24, 1984 LOCATION: CITY OF EAGAN PRELIMINARY PLAT, PHEASANT KNOLL DATE OF REPORT: APRIL 18, 1984 REPORTED BY: DALE C. RUNKLE, CITY PLANNER APPLICATION SUBMITTED An application has been submitted requesting preliminary plat ap- proval, Pheasant Knoll consisting of approximately 13.7 acres and would contain 80 townhouse units. BACKGROUND In' 1977, the City of Eagan entered into a Planned Development agree ment with Dunn and Curry for a` Planned Development named 'Blackhawk Park consisting of approximately 435 acres. Outlot A, Thomas Lake Heights Addition, is approximately 18.7 acres of the Blackhawk`Park Planned Development In the ;past few years there has been development: in Blackhawk` Park south area which consists of townhouse and single family and a'por tion was also sold off t� School District #196 for an elementar school. Also, in the Planned Development there has been some land use changes where the particular parcel under consideration was-once designated NB "(neighborhood business district), and the neighbor- hood business use transferred to the northwest quadrant of Pilot Knob Road and Diffley Road. With this transfer, the sub- ject parcel was then designated R -3 (residential townhouse), and would allow a density between 6 and 12 dwelling units per acre. In 1983, there was an application submitted for a townhouse develop- ment which consisted of approximately 120 unit. This particular developer and project has been terminated and the applicant has sub- mitted a new application which now being presented before the Plan- ning Commission is proposed to consist of approximately 18.7 acres and contain only 80 townhouse units and dedication to the City of approximately 9.25 acres for parkland which has been agreed to in the Blackhawk Park Planned Development Agreement. The access to this development will be from Thomas Lake Road. This is proposed to be a private circular drive providing access to 66 of the proposed 80 townhouse units. The applicant is proposing to provide a new street or cul -de -sac off of County Road 30 (Diffley Road) to provide access to the other 14 townhouse units. This cul -de -sac is new in this particular plan. The applicant has worked with the Park Department and has determined that providing the street would allow access to the 14 townhouse units plus provide access to the park property which will be dedicated to the City with this CITY OF EAGAN PRELIMINARY PLAT, APRIL 24, 1984 PAGE TWO PHEASANT KNOLL development proposal. Then, the City would only have to construct the parking lot and the amenties to this park versus providing also a public street. There is also some discussion regarding this ac- cess that could provide some additional security for policing be- cause of the residential units to this proposed park. This cul -de- sac will 'be constructed to City standards and meet public street criteria. The access, again, off of Thomas Lake Road is proposed to be a private drive At the present time, the applicant is pro- posing a 24 foot drive lane. In review of Chapter 13 of the City Code, it is suggested that a 28 foot minimum street be provided with this development request. Also that the setback to the garages be 25 feet from the curb to the building setback line. The applicant is, proposing to develop this parcel in a townhouse fashion instead of the eight -plex or two -story dwelling units which was originally proposed. Each of the proposed units will have a double car garage and two parking spaces in front of the unit far exceeding the parking criteria for a townhouse development project. In review of the detailed sight plan, the applicant has proposed to develop 9.45 acres of net land and dedicate 9.25 acres to the City for parkland in accordance with the overall Blackhawk Park Plan- ned Development. In reviewing this plan on the net acres or the 9.45, the applicant is proposing to construct 8.4 dwelling units per acre or is within the density allowed for this parcel which is between 6 and 12 dwelling units per acre In reviewing the site for building coverage, the applicant is proposing a 23% building coverage which is 3% in excess of the standard allowed in the City. However, in review of this particular lot coverage requirement the applicant is proposing a double car garage for each of the dwelling units. The ordinance only requires a single garage space, therefore, the applicant is in excess of the parking requirement and it appears that the variance should be granted to allow the additional parking versus requiring a lot coverage of 20 If approved Preliminary Plat should be subject to the following conditions: 1. A Development Agreement shall be required and signed prior to the construction of any of the dwelling units. A detailed grading, drainage and erosion control plan shall be submitted and approved by City Staff prior to final plat approval. The Homeowners Association and Bi -laws shall be submitted to the City for review prior to the final plat application. A variance from the 20% lot coverage shall be granted in order to allow the double car garage per dwelling unit. 4. The applicant shall dedicate adequate rights -of -way for Thomas Lake Road and Diffley Road (County Rd.30) and also provide all easements as requested by City Staff A detail landscape plan shall be submitted and an adequate land- scape bond shall be required and not released until one year CITY OE EAGAN PRELIMINARY PLAT, PHEASANT KNOLL, PAGE THREE APRIL 24, 1984 after the landscaping has been completed. The Park Committee shall review this proposed cul -de -sac street and determine how this Proposed Development would fit into the overall Park master plan for Heine Lake Park. MEMO TO: THE ADVISORY PLANNING COMMISSION, C/O DALE C. RUNKLE, CITY PLANNER FROM: RICHARD M. HEFTI, ASSISTANT CITY ENGINEER DATE: APRIL 18, 1984 SUBJECT: PHEASANT KNOLL PRELIMINARY PLATT The Engineering Division of the Department of Public Works has the following comments in regard to this proposed development for con- sideration by the Advisory Planning Commission and the City Council. DRAINAGE /TOPOGRAPHY As its name suggests, this proposed development sits on a knoll with an elevation of approximately 940. From there it slopes very steeply to the east in the direction of Heine Pond with a water eleva- tion of approximately 874. The westerly portion of this site slopes to the west at a much gentler slope with the elevation along the west property line being approximately 918. All runoff presently ends up in Heine Lake (Pond AP -5). Pond AP -5 has a positive gravity outflow to the the north and eventually into the Minnesota River. The master drainage plan, as depicted in Figure 1, indicates a relationship with this proposed development with respect to the downstream storm sewer. According to the Dakota County soil survey maps, the soils on this site consist of silty loam over the less severe slopes and sandy loam along the steeper slopes. Both are susceptable to erosion. Subsequently, the developer will be required to submit a detailed erosion control plan along with his grading plan. This plan should be implemented during the entire construction period of this pro- posed development. Both the grading and erosion control plans shall be submitted to staff for review and approval. The grading over this proposed development will not significantly alter any current draining patterns. However, all drainage from this entire site is to be collected by internal storm sewer and directed into the trunk storm sewer just west of Heine Pond. UTILITIES Existing utilities available to provide service to this proposed development consists of a 12" trunk watermain along the south of County Road 30, a 12" trunk watermain on the west side of Thomas Lake Road, and a 27" trunk sanitary sewer east of this proposed development and west of Heine Lake. All utilities are of sufficient size, capacity and depth to provide necessary service. The proposed watermain should loop through this site by connecting the existing 6" stub off of Thomas Lake Road to the 12" trunk water main along the south side of County Road 30. Also, a 6" watermain ENGINEERING REPORT PHEASANT KNOLL PRELIMINARY PLAT APRIL 18, 1984 PAGE TWO shall be stubbed to the west property line of this proposed develop- ment. Meanwhile, the sanitary sewer should also be stubbed to the west property line of this proposed development and be deep enough to provide future service to the parcel to the west. Likewise, storm sewer should be stubbed to the west property line of this proposed development and be at a depth sufficient to provide service to the parcel to the west. STREETS This proposed development is bordered by County Rd. 30 (Diffley Road) on the north and by Thomas Lake Road on the southwest. County Road 30 is under the jurisdiction of the Dakota County Highway De- partment. It is presently a two lane road with bituminous surfacing. Meanwhile, Thomas Lake Road is designated a city community collector street which is built to its ultimate design cross section. The proposed access for this development is from Thomas Lake Road by means of an internal looped private street. It is recommended that the entrance to this proposed development be at least 36 feet wide. Where it branches off it should be a minimum of 28 feet wide with concrete curb and gutter and constructed to city standards. Access to Phase 4 of this proposed development along the easterly portion is by means of a cul -de -sac off of County Road 30. This cul -de -sac is proposed to be a dedicated city street and is within city code for length. This proposed access point is approximately 100 feet east of an existing entrance off of County Road 30 to this property. This proposed entrance would be approximately 900 feet east of Thomas Lake Road and 850 feet west of Heine Strauss Road. To the staff's understanding, this satisfied Dakota County Highway Department's criteria of maintaining at least 1/8 mile (660 feet) between access points onto county highways. Nevertheless, this access point will undoubtedly be reviewed by the Dakota County High- way Department since it abutts a ccunty road and their recommenda- tions will be final. The slope of County Road 30 at this proposed intersection is ap- proximately 4 The average slope approximately 450 feet west of the proposed intersection is approximately 6%. In contrast, the slope of County Road 30 approximately 450 feet east of Heine Strauss Road approaches 8 Staff has checked with the Police Dept. to see if the Heine Strauss and County Road 30 intersection has been a traffic problem in the past and received a negative response. Subsequently, staff does not feel this proposed access onto County Road 30 at this location by this development will pose any signifi- cant problems. Since a trailway exists along the Thomas Lake Road easterly right of -way line, the requirement for trailway construction along Thomas Lake Road for this development is thereby relieved. However, the Parks Commission is considering proposing a trail from Thomas Lake Road to the proposed cul -de -sac. If this is approved by the Parks ENGINEERING REPORT PHEASANT KINOLL PRELIMINARY PLAT APRIL 18, 1984 PAGE THREE Commission, then costs for installing this trail will be the res- ponsibility of this development. RIGHT -OF- WAY /EASEMENTS A 55 foot half right -of -way is recommended by staff to be dedicated for CountyRoad 30. The right -of -way for the proposed cul -de -sac shall be dedicated with a minimum width of 50 feet and a minimum radius of 55 feet. The latter is required to maintain a city mini- mum standard of an 8 foot boulevard. No other right -of -way will be required to be dedicated. Easements of sufficient width shall be dedicated over all city maintained utilities. In addition, 10 foot utility easement shall be dedicated adjacent to all publicly dedicated right -of -way with a 5 foot drainage and utility easement dedicated adjacent to the exterior lot lines for Lots 23 of Blocks 1, 2 and 3 and Lot 15 of Block 4. Lastly, a 10 foot trailway easement shall be dedicated adjacent to the County Road 30 right -of -way and over the internal trailway if required. ASSESSMENTS All trunk area assessments have been levied over this parcel. All laterial benefit from existing trunk utilities have been levied with the exception of laterial benefits from trunk watermain along County Road 30. Subsequently, this development shall be responsible for laterial benefits from trunk watermain for 300 front feet at the rate in effect at the time of final plat approval. Currently, this would amount to $3,252.00 ($10.84 per front foot X 300 front feet). Since this proposed development abutts a county road, it is city policy for this development to prepay a lateral benefit for multi- ple equivalent street construction at the rate in effect at the time of final plat approval. Currently, this would amount to $34,470.00 ($57.45 per front foot X 600 front feet). Of course, the final amount will be determined by the distances as final platted. All costs for internal streets and utilities the cul -de -sac, will be the sole responsibility of this development. I will be available to discuss in detail any aspect of this report with the Advisory Planning Commission at the meeting on April 24, 1984. Respectfully submitted, Richard M. Hefti, P.E. Assistant City Engineer RMH:jbd. ENGINEERING RECOMMENDATIONS FOR PHEASANT KNOLL PRELIMINARY PLAT 1.

REPORT: APRIL 23, 1984 GREG H. INGRAHAM, PLANNER I COMMENTS The applicant is proposing to construct 10 three story apartment buildings with 24 units per building and 1 three story apartment building with 20 units and a community room and exercise area.. The 11 buildings and the 12 garage structures cover 17.4% of the parcel and create a density of 13.5 units per acre. The proposed structures meet the setback requirements of the Eagan City Code. The applicant proposes 260 garages and 268 open parking spaces. The City Code requires 390 open parking spaces and 260 garages where the units are primarily for rental use or 260 garages and 260 open spaces for primarily owner occupied usage. The ap- plicant intends to tie the use of each garage to a specific unit which would reduce the need for open parking spaces. According to the original Planned Development schedule this parcel is listed as Phases 4 and 5. As part of Phase 4 the Metcalf Drive .connection was scheduled to be constructed.. The connection and phas- ing plan should be addressed in conjunction with this application. The park dedication requirements for Cinnamon Ridge Planned Unit. Development are behind schedule. See the attached memo from the Dir ector of Parks and Recreation for details on this issue. r< An appliction has been subinitted .requesting .preiiminary plat appro- val for Cinnamon Ridge 7th Addition. The plat consists of 260 ment units on 19.2 acres.' These would be. located at the:northwest quadrant of Cedar Avenue and Cliff Road.. A ZONING' AND LAND USE Presently the parcel is zoned R -4 (Residential. Multiple) ',under- the Cinnamon Ridge Planned Development. The area was established' "as a high density area. in the planned development agreement initiated in. June, 1981. The, Comprehensive Guide Plan. also :.designates ._the property as R -IV 12 units/acre) CITY OF EAGAN CINNAMON RIDGE PLANNED DEVELOPMENT PAGE 2 APRIL 23, 1984 The orientation of the buildings and usage of the topography would seem to mitigate some of the road noise from Cedar Avenue. However the applicant should submit a landscaping plan which would attempt to further reduce the road noise at the proposed units. If approved, the preliminary plat should be subject to the following conditions: 1. The plat be subject to the Dakota County Plat Commission's review and comments since the plat abuts a county road. 2. The plat be subject to the Minnesota Department of Transporta- tion's review and comments since the plat abuts a state road. Detailed grading, drainage, erosion control and utility plans shall be approved' by the City Staff A detailed landscape plan shall be approved by the City Staff and a landscape bond shall be submitted and not released until one year' after the landscaping has been completed. 5. The park dedication requirements be completed to the satisfaction of the Park Committee and City Staff. 6. A determination should be made as to the implementation of the Metcalf Road street connection. All applicable ordinances in the City shall be complied with. 7. A development Agreement shall be prepared and approved by the City of Eagan prior to construction. MEMO TO: DALE RUNKLE, CITY PLANNER FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: APRIL 18, 1984 SUBJECT: CINNAMON RIDGE PUD The Cinnamon Ridge Planned Unit Development Agreement as approved in the fall of 1981 provided for the dedication of two parcels of land for parks purposes. In addition, a cash dedication require- ment was also necessary as the land parcels were not of sufficient size to meet the City's parks dedication requirements. In addition to the cash and land dedication, also agreed to as part of the City's parks dedication requirements, was the grading and seeding of the central two and one -half acre park area. This grading work has not been completed and was to have been done prior to this time. The specific requirements for the two and one -half acre park area were called out in a concept plan prepared by the City. The concept plan provided that a five -foot wide, bituminous pathway through the park connecting the two access points be installed. Part of this pathway was to be a bomonite surface to accent the entrance to the park. Also to be included was a bituminous mat suitable for use as a half -court basketball. This area would be near by or adjacent to a proposed play apparatus area to be installed by the City. Also included in the development agreement was for a five foot -wide bituminous trail of approximately 125 feet in length into the second, northern section of the park which is beneath the NSP power line easement. All of the above shall be approved by staff as to the exact location, placement or a specific requirement regarding grading and seeding. These requirements have been spelled out previously in the planned unit development agreement and in numerous letters or other corres- pondence with Zachman Homes. The proposed preliminary plat for Cinnamon Ridge 7th Addition shall b_ s bject to a cash dedication requirement, less remaining parklan.� dedication credits, as a condition of plat approval.

RUNKLE, CITY PLANNER FROM: ED KIRSCHT, ENGINEERING TECHNICIAN DATE: APRIL 19, 1984 SUBJECT: CINNAMON RIDGE 7TH ADDITION PRELIMINARY PLAT The Engineering Division of the Department of Public Works has the following comments regarding the proposed development for consider- ation by the Advisory Planning Commission and City Council. DRAINAGE /TOPOGRAPHY This proposed development is located directly west of new Cedar Avenue and north of Cliff Road and is located in the southwest 1/4 of Section 30. This property is non wooded with the southerly 1/3 of this subdivision sloping to the east toward new Cedar Avenue and then would drain to the north along Cedar Avenue to an existing storm sewer. The north 2/3 of this subdivision is proposed to slope to the northwest and would drain into an existing storm sewer in Slaters Road east of Cinnamon Trail. This proposed development is located within the A Major Drainage District as defined by the master storm sewer plan (see Figure 1 attached). WATERMAIN, SANITARY SEWER AND STORM SEWER Watermain, sanitary sewer and storm sewer of sufficient size and capacity exist within the proximity of this proposed development to provide service to it. The City will require a petition to con- struct the necessary utilities or; if utilities are installed under private contract, then the plans and specifications shall be prepared by a Registered Engineer and submitted to the City for approval. STREETS Access to this proposed plat is by Cliff Road from the south and Slater Road from the north. It is proposed that Slaters Road will be constructed through this plat from north to south and will pro vice excellent traffic flow. The City will require the installation of a left turn lane on Cliff Road for newly proposed Slater Road as per Dakota County requirements. EASEMENTS /RIGHT -OF -WAY The City will require utility and drainage easements ten feet (10') in width adjoining all street and five feet (5') in width adjoining side and rear lot lines. The City will require utility easements a minimum of fifteen feet (15') in width for all public utilities not constructed within the street right -of -way. This item will be reviewed again when the utility plans for this subdivision have-been submitted along with the final plat. EROSION CONTROL PLAN The developer shall submit an erosion and sediment control plan to the City for review and approval.

Kirscht Engineering Aide cc: Rich Hefti EXISTING ZONING: PD (PLANNED DEVELOPMENT DISTRICT WHICH INCLUDED; SINGLE- FAMILY, TWIN HOME AND QUADRAMINIUM <UNITS COMMENTS CITY OF EAGAN SUBJECT: REVISED PRELIMINARY PLAT BIRCH PARK ADDITION APPLICANT: SIENNA CORPORATION, ROD HARDY LOCATION: OUTLOTS A, B, C, D, E, F WINDCREST 2ND ADDITION DATE OF PUBLIC HEARING: APRIL 24, 1984 DATE OF REPORT: APRIL 19, 1984 REPORTED BY: DALE C. RUNKLE,;CITY PLANNER APPLICATION SUBMITTED: An application has been submitted to replat a portion! of Windcrest 2nd Addition to Birch Park Addition consisting of approximately 42.5 acres and containing 77 dwelling units located on Outlots A through F, Windcrest 2nd Addition. In 1979 a development proposal was submitted for a planned develop ment consisting of approximately 80 acres and was proposing to develop 56 single family homes, 38 twin home units, and 112 quadra minium units, for a total density of 206 dwelling units. The higher density was proposed on the, north with the twin homes and quadraminiums, and the single- family being developed on the south. Also included with this development proposal was some park dedication in order to link the City Hall to Patrick Eagan Park. The present development that has taken place on this partic- ular site is on the northern portion, which is the only area that had access to sanitary sewer. As you are aware, the City has authorized the extension of a trunk sewer and lift station which will have to be constructed in the center to southern portion of this, proposed development which will then run easterly across McCarthy property to Gabberts development and continuing easterly to the Lexington Square develop- ment. With this sewer extension, the rest of this parcel becomes accessible to utilities and would allow development. In 1979 the City reviewed this particular development and allowed 206 dwelling units. The applicant is now proposing to replat a portion of this into all single family lots. The portion being replatted allowed 36 quadraminium units, 8 twin homes units and 56 single family units. The applicant is proposing to• plat 77 single- family lots or,a net effect of a 23- dwelling unit reduction. CITY OF EAGAN REVISED PRELIMINARY PLAT, BIRCH PARK APRIL 24, 1984 PAGE TWO The northern portion of the proposed plat would remain the same where the same street connections would be provided, however, the replatting of some twin home and quadraminium lots would change to smaller, single- family lots with the smallest lot being 10,100 square feet. The lots proposed would have a minimum of 65 -foot lot widths but the depths are substantial to provide quite a bit of liveable area per lot. The average lot size proposed is 18,100 square feet or approximately 6,000 square feet above the minimum R -1 lot size requirement. Included with this report is a matrix showing the lot and block configuration and the lot size requirements for each The circulation or access to this development would be the same as what was originally proposed. This preliminary plat would extend. Denmark Avenue from Wescott Road to Deerwood Drive and Denmark Avenue would be the main street providing access to this development. The street continuity to the north is the same as what was originally proposed with the Windcrest Addition. The southern portion of the plat changes in regard to interior street access. As you may or may not recall, there was a great deal of discussion regarding access onto Deerwood Drive and also in how access would be obtained to the parcel directly west of this development proposal. At that time, the City Council requested that an additional street be provided from Denmark Avenue to the property to the west. This street was proposed to be Fawn Ridge Drive and proposed to cut through the northerly portion of the lots abutting Deerwood Drive. This would then provide access to the west and also not allow all of the direct accesses onto Deerwood Drive. After re- evaluation of street grades and cost to construct Fawn Ridge, the applicants again are proposing not to construct Fawn Ridge Drive but to eliminate this street and provide direct access onto Deerwood Drive. In reviewing the costs and the grading which would have to be done to construct this street, the developers feel it is not feasible to construct this road in regard to costs involved, also in regard to the grading and devastation to the existing property. The issues now arise again in regard to access onto Deerwood Drive and access to the property to the west. Presently, it is the City's understanding that the developers now of Birch Park Addition also have an option to buy the parcel to the west which does not have access at the present time It is staff's understanding that the applicants would propose to purchase the parcel to the west and obtain fill from the con- struction of I -35E and substantially fill the valley in order to provide a direct access onto Pilot Knob Road., This then should eliminate the issue as to how access could be obtained to the property to the west. CITY; OF EAGAN REVISED PRELIMINARY PLAT, BIRCH PARK APRIL 24, 1984 PAGE THREE The applicants are proposing to dedicate the same open space as the City had requested for park dedication. Again, this dedica- tion would then allow the City to move closer to obtain the lineal trail system from the City Hall to Patrick Eagan Park South of the park to be dedicated, or the closest to Deerwood Drive, all of the lots exceed the 12,000 square -foot requirement. However, there are some lots along Deerwood Drive which have a 70 to 75 -foot lot width at the setback but the square footages are far in excess of 12,000 square feet- of the lots abutting Deerwood Drive have a minimum of, 100 -foot lot width and range from 12,000 square feet to 35,000 square feet in area. If the revised preliminary plat approved, it should be subject to the following conditions: DCR /kf A revised planned development agreement be drafted incor- porating the proposed land use changes and possibly an underlying zoning of R -1 be incorporated on this preliminary plat portion. An agreement be entered into by the City and developer that if Fawn Ridge Drive is eliminated, that proper access be provided to the west. The planned development incorporate this specific plan for lot size and lot configuration. The plat be subject to the Park Commission's review and comments regarding park dedication. Adequate rights -of -way and easements be dedicated as requested by City staff. 6. All other City ordinances shall be adhered to. ENGINEERING RECOMMENDATIONS 1. The City will require a petition to construct the proposed storm sewer lift station No. 12 and outlet for Pond JP -6. 2. The City will require a petition to construct the proposed 12" watermain through this plat. 3. The City will require a petition for the upgrading of Deerwood Drive. 4. Utility and drainage easements shall be dedicated as referenced in this report. 5. If the utilities and streets are constructed under a private contract, the plans and specifications shall be prepared by a registered engineer in accordance with the engineering guidelines; otherwise, the developer shall petition the City to construct the necessary utilities and streets. 6. All future costs for public improvements shall be the sole responsibility of the developer except for the watermain oversizing and one -half the appropriate cost of Deerwood Drive. MEMO TO: THE ADIVISORY PLANNING COMMISSION, C/O DALE C RUNKLE, CITY PLANNER FROM: EDWARD J KIRSCHT, ENGINEERING AID DATE: APRIL 18, 1984 SUBJECT: BIRCH PARK ADDITION The Engineering Division of the Department of Public Works has the following comments regarding this proposed development for consideration by the Advisory Planning Commission and the City Council. Drainage /Topography This proposed development is located directly North of Deerwood Drive and South of Windcrest 1st and 2nd Additions and is located in the East 2 of the Northwest of Section 22. The existing topography consists of rolling hills with the North 2 sloping to the South and the South portion (which is heavily wooded) of this proposed development sloping to the North towards existing Pond JP -6 and JP -10. Figure One (1) illustrates the relationship of this proposed development being located within the J major drainage district as defined by the Master Storm Sewer Plan. A major part of this plat drains into Pond JP -6 which in turn, by the proposed lift station #12, will be pumped to the East into Pond JP -10. The developer shall submit a petition to the City Public Works Department to have the necessary lift station and storm sewer be constructed. The developer shall contact the Department of Natural Resources and obtain the necessary permits required for any proposed construction near the JP -6 ponding area, if appropriate. Watermain and Sanitary Sewer Watermain and sanitary sewer of sufficient size and capacity exist within the proximity of this proposed development to provide service to it. The developer shall submit a petition to have the City construct a 12" watermain through this property as per the City of Eagan Master Water Distribution Plan. Proposed watermain dead end in the proposed cul -de -sac shall be looped. Streets Access to this proposed plat is by Denmark Avenue from the North through Windcrest 1st Addition and Deerwood Drive from the Southwest. The developer should submit a petition to have the City upgrade Deerwood Drive along the South plat boundary. The City will require a sidewalk be constructed along the South right -of -way line of Deerwood Drive. It is proposed that Denmark Avenue will be constructed through this plat from North to South and will provide excellent traffic flow. Sidewalk shall be constructed along the West right -of -way line of Denmark Avenue from Deerwood Drive to the proposed Windcrest Avenue in accordance with City policy. ADVISORY PLANNING COMMISSION April 19, 1984 Page 2 Easements Right -of -Way The City will require utility and drainage easements ten feet (10') in width adjoining all streets and five feet (5') in width adjoining side and rear lot lines. The City will require utility easements a min.of,15'in width for all watermain, storm sewer and sanitary sewer not constructed within the street' right -of -way. This item will be reviewed again when a utility plan for this area has been submitted along with the proposed final plat. The City will require drainage and utility easements over and across all property within this proposed plat below the 818.0 elevation which is the proposed high water elevation of Pond JP -6. Erosion Control Plan The developer shall submit an erosion and sediment control plan to the City for review and approval. Assessments Area assessments shall be paid at the time of final plat or a request can be made to spread these assessments over a period of years (as per City policy) by executing a Waiver of Hearing. The final amount of area assessments for watermain and storm sewer will be determined by the City according to the rates in effect at the time of final plat approval. SPECIAL ASSESSMENT REVIEW Listed below are the current proposed trunk watermain and storm sewer assessments which will be the responsibility of the developer in accordance with the net areas as final platted. 1. Watermain 32.51 Acres 1,120 per Acre 2. Storm Sewer 32.51 Acres x 43,560 x .045 All other related trunk assessments have been levied. VI.

As way of background to this item, please read the attached letter addressed to Miss Mary Olson who is a resident of the Heine Strasse Addition in which the proposed trail is adjacent to her residence. You will note by the letter that this item goes back many years in its history. To be determined by the Advisory Commission is whether or not it is still their intention to make this trail connection as previously determined by the Advisory Commission or if th =r- is a change in mind and intent of the City regarding this tra Direct KV /jj Enclosure Parks Recreation 3830 PILOT KNOB ROAD, P.O.

SMITH JERRY THOMAS THEODORE WACHTER Council Members THOMAS HEDGES City Administrator EUGENE VAN OVERBEKE City Clerk We have discussed the issue of a trail adjacent to your home on Heine Strasse on and off for a period of months. Recently, you again contacted me to conclude this trail issue. Let me first explain some of the history of this trail /easement. In March of 1977, the City received a preliminary plat for Heine 1st Addition. As one of the conditions of plat approval, the developer, Mr. Carl Heine, agreed to provide a 15 ft. trail easement. Later, Mr. Heine failed to submit the necessary documents providing this trail where it was originally intended to go. In order to obtain the trail easement as Mr. Heine had originally agreed to, the City withheld the issuance of building permits pending the completion and his compliance with the terms and conditions of the plat /development agreement. Finally, at the August 1, 1978, City Council meeting, the City Council and Mr. Heine reached an agreement to the trail dedication at its current location. With the platting of Thomas Lakes Heights, which is the development immediately to the north, the City Council required the developer to provide a bituminous trail from Clemson Court to the end of the easement in the Heine Addition. This provided a linkup between the two Additions with the intended purpose of providing walkers and bikers from the Heine Addition with access to Thomas Lake Road and locations to the south versus a more hazardous route along County Rd. 30. You had called me, I believe, last Spring, about the trail and the problems that you were experiencing. You requested that something be done with the overgrowth of vegetation on the trail, washouts on the trail and the incidence of people cutting through your yard. Subsequently, parks maintenance personnel did come out to cut and clear the trail and did a small amount of rough grading. THE LONE OAK TREE. THE SYMBOL OF STRENGTH AND GROWTH IN OUR COMMUNITY MARY OLSON APRIL 10, 1984 PAGE 2 You disagreed with me for various reasons of your own that the City would install a bituminous mat on the trail easement. I did not proceed with the paving work at that time partly because of your strong objections and also because of the construction /yard- work going on the adjacent lot. I did receive a call from this homeowner on October 28 questioning when the trail would be installed. At that time he had no objections to the trail being completed. This almost brings us up to the present time. After your initial call in March, I had as I agreed to have the City Engineer look at the trail to determine what, if any problems we might have with the installation. He has responded, indicating that the work could be completed by the City crew with its tailgate paver. Some excavation work would have to occur so a crushed rock base can be laid down. The bituminous mat could then be installed. He did not anticipate any problems with the work. Today, April 9, you again contacted me indicating that you believe the trail may not be in the correct location. Its actual location may be to the west of where it appears to be at present. A survey will have to be performed to determine the exact location. It has been, and I believe it still remains the City's intent to have this trail installed. However, before I proceed with having this work proceed as originally intended, I am placing the item before the Advisory Parks and Recreation Commission at its regular meeting on May 3. By copy of this letter, which will be included in the information packet to the Commission to go out about April 30, I will be informing the Commission concerning this issue. I understand that you will probably be in attendance at that meeting. If you would care to contact me during the week preceeding the meeting I can let you know where on the agenda this item will appear and the approximate time that the Commission may get to it.

More money is spent each year in this country on recreation than for national defense $77 million more in an estimated 1983 market of $244 billion. Americans are spending 12 percent of their per- sonal income on leisure and recrea- tional pursuits, more than they pay for transportation or medical care. These figures illustrate the double edged sword that is challenging com- munity parks and recreation officials as the public's leisure time increases, but the money available to provide the pub- lic facilities and programs shrinks. Often, when budgets get tight, local governments trim parks and recreation department funding. The parks and recreation professional is then left with less capital, at a time when the public is calling for more. Despite the problems, some parks and recreation programs are managing to maintain and improve existing activities and facilities, through innovative fi- nancing, such as user fees and other techniques. Others are even branching out into new areas to the benefit of local government employees and the communities they serve. This trend is the subject of our cover story this month, researched and writ- ten by Associate Editor Constance Brit tain. Parks and recreation departments are becoming more involved with fit ness programs, reflecting the public's new concern with physical well- being and nutrition with fitness and well- ness. The concept is not new. In 1909, Ar- thur Grant, the first editor of this mag- azine, then called The American City, said in his first editorial, "They [Amer- ican cities] have found that congestion breeds consumption, and that parks are better investments than potter's fields. It has been shown that if we give boys and girls no place for whole- hearted play, we need not be surprised when some of them grow up into hoodlums and prostitutes." Then, as now, communities were trying to provide recreational opportu- nities for their residents, both to im- prove the community and the lifestyles of its citizens. At first, the trend was to build facilities and establish programs. But the focus was on the betterment of the people and the community. It could be argued that this perspective has been pushed to the background as the em- phasis turned from people to facilities. If so, we may be coming full circle as communities are realizing the benefits of providing physical fitness programs for employees and citizens, to the benefit of both. Many American businesses, perhaps spurred by the Japanese experience with group exercise in the workplace, are finding that keeping their employees physically fit can reap a number of ben- efits for the business itself. Productiv- ity, morale, efficiency and attendance all improve when employees participate in company- sponsored fitness pro- grams. The only loser is health care costs, which studies indicate may drop by one third. For business, that trans- lates into an improved bottom line and happier and healthier employees. Local governments are discovering that the same can also hold true for them. Several communities around the country have initiated self -help, fitness- type programs, either for public em- ployees or for citizens. They reason that physically fit and healthy employees are better able to serve the public. It doesn't hurt any, either, that those employees also report to work more often and do their jobs with more enthusiasm and ef- ficiency. As parks and recreation programs move into this new area, while main- taining their traditional responsibilities, government needs to develop policy re- garding the recreation field. Americans spend one -third of their waking hours in recreational activity. New government recreational policy considerations must be based on a more complete under- standing of that demand. Creative thinking is needed by federal and state government officials when considering funding for local commu- nity leisure programs. Operating and maintenance costs of recreation pro- grams have been pushed past their ca- pacity at the local level. New ideas and concepts are needed. We need to plan now for the recrea- tional needs of this and future genera- tions. Without that planning, and with- out secure and adequate funding for programs and facilities that will be in increasingly greater demand, the parks and recreation programs of the future will be woefully inadequate.

Albany Atlanta Manchester Minneapolis San Francisco Circle No. 3 On Reader Service Card The Physiolo of Acceleration R When I was on the staff of C /D, back in the mid- 1960s, acceleration puzzled me. In those days I was a member of a kind of loyal opposition to generally available technology. (We were the ones who knew we would lose on the straights but were still talking about catching up on the turns.) I followed road racing rather than drag racing, finding handling more interesting than all that zero -to -sixty stuff. But the quar- ter -mile sport had a powerful if unac- knowledged effect on the way all of us thought about automobiles. It wasn't that I was prejudiced against acceleration; I just thought it was a bit simple- minded. I was comfortable enough with its technical aspects. I un- derstood its uses, and definitely relished using it. I loved that surge as much as anyone. At C/D we were just beginning to get interested in motorcycles, and I was perfectly willing to admit how much fun they were. Most of that fun seemed to have to do with their vigorous accel- eration. I wondered why that sensation was so stimulating, but I could never quite figure it out. We were also fascinated by pure pow- er and the control thereof. Hand over control of a running engine to someone and, I guarantee you, he will blip the throttle. He will press the pedal, work the control, toy with the power surge. But speed alone turns out not to be enough. We get jaded; we want the push of acceleration, the rising curve. I suffer from a reductive turn of mind. Looking at motorcycles, for example, I always discounted noise and wind as mere side effects. (Acceleration in quiet, enclosed vehicles is also fun.) There- fore, I thought, the pleasurable sensa- tions of acceleration had to be a product of the stimulation of the pressure recep- tors in the butt —the sense of touch in Getting off on speed, and other thrills. BY JOHN JEROME those parts of you that make contact with the accelerating vehicle —and of minor disturbances to the balance mechanism of the semicircular canals of the inner ear. But these seemed to me to be awfully minor neural hardware to generate the kind of sensation you get from a large engine attached to a short gear. How could receptors that are such physiological pipsqueaks create so rnuch fun —and therefore so much me- chanical sport? I was overlooking muscle, and its sen- sory power. Skeletal muscle is the larg- est sensory organ we have, and it reads acceleration throughout the whole body, I never dreamed such a thing was possible. You can —you do —read accel- eration right down in your little finger. Acceleration is one of the most massive sensory experiences we ever have. The sensors that count, acceleration wise, are the proprioceptors —the "self sensors"— little specialized nerve end- ings that are embedded in the muscle, the tendons, and the joints, that read and report on body position, move- ment, and loading. They are the memo- ry banks your coach was talking about when he spoke of "muscle memory" (al- though that term is misleading). They are the neural devices that weigh and judge and perceive whatever you do with your musculoskeletal system, from guiding a forkful of pasta safely into your gob to catching the rear end of your Jncly car when it starts to break loose at 220 mph. Some of us get very good with our proprioceptors. The ones who do are usually called athletes, of which racing drivers —drag, road, or round and -round —are one special sub- category. Those of us. who don't get good at proprioception are called spectators. The way human muscle acts as a sen- sor requires a kind of neural rigging that would have made the late Colin Chapman proud. Muscle stays alive by means of a complex neural loop that connects sensory (afferent) nerve end ings to the central nervous system and in turn to effector (efferent) nerve endings. This loop maintains in the muscle a steady state of low -grade con traction that keeps it ready for use: mus- cle tone. (Muscle tone has been likened to the idle of a car's engine.) Snip the loop at any point and the muscle that it innervates will atrophy like that of a limb in a cast. Muscle tone in turn maintains the stretch reflex, which is the muscle's automatic resistance to the displace- ment of the limb. When the doctor taps your kneecap, he's really stretching the tendon that connects the kneecap to the thigh muscles. That stretch fires pro prioceptors in the muscles that tell the spine there's a mismatch in the length of those muscles. The spine in turn sends signals back to the muscles to match up their length, which signals make you kick your foot. When you twist the throttle on a mo- torcycle, you're changing the loadings on most of your musculoskeletal sys- ACCELERATION tem. Acceleration snaps your head back: your neck and shoulders contain per- haps the richest bed of proprioception in your body, charged with the task of keeping your eyes level and your bal- ance perfect, so that you will be ready to take action no matter what kinds of up- set the rest of your skeleton is being put through. Acceleration snaps everything back; you feel it just the way your face felt the pull of gravity plus centrifugal force at the bottom of the arc of the playground swing. At that moment gravity tugged harder at the mass of your facial flesh, and that attempted dislocation of the mass fired thousands of proprioceptor endings in the facial rnuscles. It was an unusual feeling and you experimented with it. (Kids are the ultimate sensual- ists, doing everything just to find out what each new experience feels like. This helps explain everything from roller coasters to teen -age pregnancies.) The same force at work on your facial muscles was also at work on the rest of Some of us get very good with our proprioceptors. The ones who do are usually called athletes. you, of course, giving you that sweet lit- tle perceptual thrill, almost a sexual thrill, that you get when your entire body is being worked upon by forces larger than usual. Hard acceleration is the playground swing times ten, times a hundred, the same category of forces raised to breathtaking new heights. Every ounce of mass on your body is under a dislo- cating force that seems to want to pull the muscle from your bones, to pool your blood and your flesh on the back- side of your skeleton. Your propriocep- tors light up your central nervous sys- tem like those rows of control panels at Mission Control in Houston. I'm thinking of acceleration in the drag -strip sense, as a straight -ahead push. C /D's technical editors, who know a lot more about physics than I do, will tell you that in any kind of driving there are accelerations in every direction, ac- celerations in vectors and angles, side loadings and (heart- stopping) unload- ings. There is no end to the ways you can find to get your frame tossed about and titillated by external forces and changes of direction. Every one of them carries this kind of proprioceptive thrill. Every one of them cranks on all those nerve endings, pleasuring you with new sensations. Imagine the neural fireworks for a Formula 1 driver practicing his craft, taking all that horsepower through as complex a series of patterns as the course can dish up. (Looked at this way, aerodynamic bodywork is a complicated way to increase the possible loadings, to boost the forces at work right up to the breakaway point.) Imagine the balanc- ing act, the vectoring that's going on, as the driver works those tiny little con- trols— steering, gas, brakes, gears —to cut a way through all that sensation, to come up with the alignments and ar- rangements that will keep the car (and his body) moving in the chosen direc- tion at the fastest possible speed. Skill at that balancing act is usually credited to kinesthetic sense, which is a rather vague term for the capacity to read and react to the signals from the proprioceptors. It's a sense that can be improved with practice. At its higher levels it is a very acute sense indeed. It's the sense that allows the diver to come out of his tuck —after three and a half somersaults from 33 feet in the air —at the precise instant that will enable him to enter the water absolutely vertical and with minimum splash. It's' the sense that tells the trout fisherman just when and how hard to set the hook —on the basis of information gathered from no sources other than the muscles of the hand, wrist, and arm. It's the sense that allows the good tennis player to read— from the torque on the racket handle just how far off- center the ball has met the racket face (and, on the basis of that information, to fire enough muscle fi- bers of the wrist and forearm to com- pensate and slam the forehand wi two inches inside the cross -court tine). It is the sense that enables the racing driver to make sure that there is some- where very close to 11,500 rpm (and third gear) available to the drive wheels —and that the accelerator pedal has just started down —at the precise in- stant the drive wheels drift out to the 132 CAR and DRIVER ACCELERATION last inch of useful traction on the exit of the turn. (It is equally involved in deceleration, of course. Braking a car in racing has al- ways seemed to me to be one of the most elegant problems in sports. You have to select the latest possible mo- ment that you can apply the brakes to slow the car just enough to go through the corner at the fastest possible speed. You must apply the brakes as hard as possible for the shortest possible time that will bring the tire surfaces to the point just short of sliding. Your job is to approach, but not exceed, these values. You can't tell when you exceed any of them until you do so. It is a problem of adjustable negatives, of going faster by decreasing less. Done right it is a dem- onstration of major- league powers of proprioception.) Sounds like fun to me. Anyway, that, I think, is why acceleration is such a kick. It's a great deal more than some touch sensors on your butt and your semicir- cular canals (but it's also that, too, some outrageous signaling from those dumb organs). It's fun because of that entire great, thrusting sensory Load, all those neurons crackling away, telling you how alive you are. Acceleration is a sensory intensifier. Most sports —at least the high- effort, all -out ones that require that you do something as hard or fast or long as you can —are routinized ways of firing off every neuron you can summon up. That's where the fun lies, where the thrill comes in. Even in high -risk sports such as motor racing, the thrill isn't from exposing yourself to danger (ABC's "Wide World of Sports" to the contrary notwithstanding), but from, the bombardment of sensory stimuli. It may not be socially redeeming, but it also is not the acting -out of some Freudian death wish. It's just enjoying your nerve endings. Cigar smokers and brandy sniffers can make the same claim. The risk itself is only another vivid lit- tle intensifier, a psychological enhancer that further sharpens the sensory mes- sage. Maybe that's why many racing drivers and other high -risk athletes and performers can be so blase about threats to their lives and limbs. They're having too much fun experiencing too much in the way of sensory fireworks— to pay much attention to inconsequen- tial matters like risk. That may not be very smart —and also may not be socially redeeming —but it's a lot less scary than the idea that our heroes have this secret lust to crisp themselves in a ball of flame.
