The plan, as shown in the attached documents, is to install the swimming pool to the east of the structure. Since this project will exceed the alotted hard cover by 8.88%, we are proposing to install three on-site tanks below ground to capture the rainwater, and re-use it for irrigation purposes. This project is planned to last four to six weeks during the summer of 2017. Rain water will be stored in the three tanks (6,000 gallon total capacity) that will be connected at the lowest points of. This will allow water to flow freely between all storage tanks. One tank will be equipped with a submersible pump to reuse water for irrigation purposes. In the event that the tanks' capacity is exceded, water will feed via gravity to the drywell tank (2,600 gallon capacity). This will allow water to slowly percolate the ground. In the event that the system is completely full, the drywell tank will be equiped with a surface run off baffle. Should there be low rain amounts, this system will be connected to the home's water supply and will use that as last resort. You will find the plans for the entire system, along with site locations to better show the property and a letter from the homeowners, Jon and Janel Wittmayer.

We have only resided at this property for a short time but have lived in the surrounding neighborhoods for the past 20 years. We were excited when we purchased this property based on the size of the lot and its potential to have an in-ground pool and still have plenty of space for a yard and garden area. We were surprised when we found out that we were located so close to a lake. However,after meeting with Gregg Thompson from the City at our property and discussing options we were optimistic about the outcome of applying for our conditional use permit. Having discussed several options with our landscaper and listening to the recommendations from the City,we decided the best course of action was to install a storm water retention system. We really like the idea of a system that will recycle rain water from our property and allow it to be used to water our lawn. This"Green" use of storm water will also do a very small part in helping in the reduction of city water being used to water our lawn over the summer months. We are also pleased to know that our retention of storm water will remove excess water from entering the nearby wetland and lake. This is important to us as it helps reduce lawn chemicals from entering these protected areas. We hope you will see these benefits as well and grant us the conditional use permit for our pool. Thanks very much.

Wednesday,May 3,2017 Advisory Planning Commission 3830 Pilot Knob Road Eagan,MN 55122 RE:4668 Pine Cone Circle;Conditional Use Permit Dear Ms.Sarah Thomas, In regards to your letter dated April 27,2017,here is some clarification on the items you specifically lined out. a. No clarification necessary b. No clarification necessary c. The desired pool size was already reduced to 18'x 36'from what the originally desired size of 20'x 40'.The patio was already reduced from the desired size of 2,000 square feet. d. Correct.The driveway was measured only to the property line, not the curb. e. Correct.The wood deck was not included in the calculation as it has a raw dirt sub-surface beneath it. f. The pool apron is included in the hardcover calculation.It is 112 square foot of the 1612 square foot calculation. g. The fence is shown on the plan right next to the property line.It will be a non-climbable fence, over 4'in height,with self-closing,self-latching gates. h. This is understood. i. The overflow tank is located beneath the level of the cisterns keeping backflow from happening. There will be a backflow baffle installed at all gutter inflow points. j. This is understood.

AUTHORITY FOR REVIEW City Code Chapter 11, Section 11.50, Subdivisions 4C and 4D provide the following. Subdivision 4C states that the Planning Commission shall recommend a conditional use permit and the Council shall issue such conditional use permits only if it finds that such use at the proposed location: 1. Will not be detrimental to or endanger the public health, safety, or general welfare of the neighborhood or the City. 2. Will be harmonious with the general and applicable specific objectives of the Comprehensive Plan and City Code provisions. 3. Will be designed, constructed, operated and maintained so as to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area, nor substantially diminish or impair property values within the neighborhood. Planning Report—4668 Pine Cone Circle May 23,2017 Exhibit D (cont.) Page 2 4. Will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools. 5. Will not involve uses, activities, processes, materials, equipment and conditions of operation that will be hazardous or detrimental to any persons, property or the general welfare because of excessive production of traffic,noise, smoke, fumes, glare or odors. 6. Will have vehicular ingress and egress to the property which does not create traffic congestion or interfere with traffic on surrounding public streets. 7. Will not result in the destruction, loss or damage of a natural, scenic or historic feature of major importance. 8. Is appropriate after considering whether the property is in compliance with the City Code. Subdivision 4D, Conditions, states that in reviewing applications of conditional use permits, the Planning Commission and the Council may attach whatever reasonable conditions they deem necessary to mitigate anticipated adverse impacts associated with these uses, to protect the value of other property within the district, and to achieve the goals and objectives of the Comprehensive Plan. In all cases in which conditional uses are granted,the Council shall require such evidence and guarantees as it may deem necessary as proof that the conditions stipulated in connection therewith are being and will be complied with. Eagan City Code (§11.65 —Shoreland Overlay District) stipulates that impervious coverage must not exceed 25% of the lot area within the Shoreland Overlay District. However, the Code does allow for an increase in the impervious area,provided the City has: 1)Issued a Conditional Use Permit permitting an increase in impervious coverage; 2) Approved and implemented a community-wide stormwater management plan affecting the subject site; 3)Required the necessary water quality mitigation features to meet non-degradation standards for phosphorus for the nearest downstream recreational waterbody. Minnesota Department of Natural Resources (DNR) —Notice of the proposed CUP was sent to the DNR as required by the Shoreland zoning ordinance. The DNR has stated the mitigation, as proposed, is satisfactory. Planning Report—4668 Pine Cone Circle May 23,2017 Exhibit D (cont.) Page 3 BACKGROUND/HISTORY The Piney Woods subdivision was platted in 2004. The property is zoned R-1, Residential Single Family. The property is located in the Shoreland Overlay District of Holz Lake, which is a General Development Lake. Residential zoning standards limit building coverage to 20%, and in the Shoreland Overlay District, impervious surface coverage is limited to 25%of the lot area. EXISTING CONDITIONS The 19,319 sq. ft. lot contains a single family home with an attached garage constructed in 2005. The rear portion of the lot contains an existing 140 sq. ft. patio to be removed with the proposed project. The existing building coverage ratio is now 13% and the existing impervious surface coverage of the property is 20%. SURROUNDING USES The subject site is surrounded by single family homes. The property to the west across Dodd Road is zoned Agricultural, guided Low Density, and developed with a single family home. EVALUATION OF REQUEST Compatibility with Surrounding Area — The proposed in-ground pool and pool deck is a typical feature in residential areas and appears compatible with the surrounding neighborhood. Description of Proposal — Impervious coverage includes all buildings and hardcover areas: home, garage, driveway, sidewalk, and pool patio as well as the pool. The applicant proposes to construct a new in-ground pool, sized at 18' x 36' (648 sq. ft.) and a pool deck (1612 sq. ft.). The improvements, along with existing conditions, result in approximately 1,789 sq. ft. (9%) above the maximum impervious area allowed. The excess impervious area equates to a volume runoff of 1,069 cubic feet (8,000 gallons) of stormwater from a 1% frequency, 24-hour (7.47") rainfall event. A summary is provided in the table below. Square Footage Ratio to Lot Area of Impervious (19,319 sq. ft.) Maximum Allowable 4,830 25.0% in Shoreland Overlay District Existing Conditions 3,799 20% Proposed Impervious Coverage 6,619 34% Net Increase in Impervious 2,820 14% (over existing conditions) Excess Impervious Coverage 1,789 9% (over 25%maximum) Planning Report—4668 Pine Cone Circle May 23,2017 Exhibit D (cont.) Page 4 The applicants are requesting approval of a CUP and propose to construct three cisterns and two dry wells to capture the rainwater. The applicants also propose removal of the existing 140 sq. ft. patio(to be replaced with decking). The proposed pool patio is 1,612 sq. ft. in size. Effectiveness of Mitigative Measures — The applicant proposes to construct an underground rainwater harvesting system (consisting of three (3) 2,000 gallon cisterns and two (2) 1,300 gallon dry wells) that combined would capture approximately 1,149 cubic feet of storm water runoff(8,600 gallons), which would be able to contain a 1% frequency, 24-hour (7.47") rainfall event from the parcel's equivalent area of "excess" impervious surface. 1,832 square feet of rooftop area would be piped (from downspouts through buried pvc piping) to the connected cisterns. This harvested rainwater would be used as irrigation water for the lawn and landscape, utilizing an electric pump and float system. If the rainwater volume collected in the cistern system becomes insufficient to meet the demand volume for lawn irrigation,the cistern irrigation pump will be supplemented with city potable water using a float system. If during large rain events the three cisterns are filled, they would overflow to the two dry wells, which would have perforations to allow for infiltration. If the dry wells filled, overflow would surface flow across the existing overland drainage path. During the non-irrigation months, stormwater runoff would be conveyed to the buried dry well tanks. If an underground rainwater harvesting system is allowed to mitigate the "excess" imperious area, the system should be installed according to applicable guidelines in the State of Minnesota. During construction steps, the applicant should provide notification to the City, for inspection at critical construction stages (completion of excavation,prior to backfilling around cistern and dry- well tanks, completion of piping connections prior to final grading, etc.). After completion, the applicant should provide documentation (as-built drawings and volume measurements) to verify the system was constructed as designed with required minimum sizing. Eagan Water Resources has reviewed the applicant's plans, stormwater design summary and calculations provided for stormwater management and finds that the proposed plans demonstrate that the parcel's "excess" impervious surface can be mitigated to capture 100% of the runoff from the site's equivalent area of "excess" impervious from a 1% frequency, 24-hour (7.47") event. Maintenance — Because the proposed additional impervious area will be permanent, the mitigative underground rainwater harvesting system should be inspected and maintained on an ongoing basis to function properly. Since the proposed mitigative measures will be located on private property and privately maintained, the City should have legal assurances that the necessary maintenance will be performed to ensure proper functionality. Therefore, the landowner should enter into a long-term maintenance agreement with the City, in a form acceptable to the City Attorney. • Planning Report—4668 Pine Cone Circle May 23,2017 Exhibit D (cont.) Page 5 SUMMARY/CONCLUSION The applicant is proposing to construct an in-ground pool and pool deck on a single-family lot within the Shoreland Overlay Districts of Holz Lake. Shoreland zoning limits impervious coverage to a maximum of 25% of the lot size. The applicant is requesting approval of a Conditional Use Permit to allow 34% impervious coverage. The Conditional Use Permit is subject to the eight points listed in the Authority for Review section of this report, in addition to the three criteria specific to increasing impervious area that are listed in the shoreland zoning ordinance. The applicant is proposing to mitigate the impacts of the increased impervious surface by removal of the existing patio and installing an underground rainwater harvesting system. The mitigative measures should be designed to accommodate 100% of the runoff from the "excess" impervious area. If installed correctly and routinely maintained, they will sufficiently offset the excess impervious area. To ensure on-going maintenance and functionality of the proposed mitigative measures, the landowner should enter into a long-term maintenance agreement with the City, in a form acceptable to the City Attorney. ACTION TO BE CONSIDERED To recommend approval of a Conditional Use Permit to exceed 25% impervious surface coverage in a Shoreland Overlay District for an in-ground swimming pool and pool deck on a residential lot located at 4668 Pine Cone Circle. If approved,the following conditions shall apply: 1. This Conditional Use Permit (CUP) shall be recorded at Dakota County within 60 days of approval by the City Council with the following exhibit: • Site Plan dated April 19,2017. 2. The impervious surface of this lot shall not exceed 34% per the Site Plan dated April 19,2017. 3. The applicant shall provide a financial guarantee in the amount of$3,000, prior to the release of the CUP,to ensure installation occurs per the approved plans. 4. Prior to the release of the CUP for recording, the applicant shall provide a $1,000 escrow deposit for City inspections of the stormwater volume control (rainwater harvesting) system installation stages. 5. The rainwater harvesting system shall be designed and constructed to capture a minimum of 100% of the runoff from a 1% frequency, 24-hour event (7.47"), from the parcel's excess impervious surfaces (over 25% impervious coverage). Planning Report—4668 Pine Cone Circle PageMay 23,32017Exhibit D (cont.) 6. The rainwater harvesting system shall be installed according to applicable guidelines in the State of Minnesota. During construction steps, the applicant shall provide notification to the City, with minimum of 24-hour notice, for inspection at critical construction stages (completion of excavation, prior to backfilling around cistern and dry-well tanks, completion of piping connections prior to final grading, etc.). City time involved in project inspection shall be withdrawn from the applicant's project escrow. 7. As-built drawings and capture volume measurements shall be provided to the City that verify minimum storage volume requirement is being met. 8. The applicant shall enter into a long-term stormwater facility inspection and maintenance agreement, detailing the maintenance required to maintain proper operation and performance of the rainwater harvesting system, in a form acceptable to the City Attorney, to be filed in the property records with Dakota County Recorder's Office, at the applicant's expense.

Attached is an operation of the rain water collection system for irrigation use. 2. Yes,the pump tank will have a man hole riser that comes to within 6"of the surface. From there we put a 4" PVC riser in it with a screw on cap. For measuring purpose this where that could be monitored. I also decided to go with a high water level indicator.This will come on as soon as there is enough water to run the system.Off when there is not enough. 3. Yes,the drywells will be backfilled with 1.5" river rock. 1' under and 1' min. around the tank.This should enhance the infiltration to the sub soils.See attached cut away. 4. I would treat it like a septic system inspection.We would call you 4hrs prior to back filling anything. If you want to be there more than that just let me know and we will figure it out.

I have a few questions related to your attachments: 1. Can you put the operating instructions/details(including float/alarm/valve operations that you described in your email below) into a simple Irrigation Operations& Maintenance document,which can become an additional exhibit for the Maintenance Agreement for the Owner? 1 2.Will there be a way for the Owner(or City)to inspect the tank and assess/measure the current water level in the tank(s)other than waiting for the low water float/alarm to turn on? How/where will this access/measurement occur? 3. For the Perforated Tank detail,will you be placing clean,washed rock or sand below and around the sides of the tank? If so, please specify depth, rock/sand type(no limestone),and other notes on how infiltration will be encouraged for the Perforated Tanks. Sub-soil should be frost-ripped (2-foot depth, 2-foot max.spacing) across the bottom of the over-excavation for the Perforated Tank bases, prior to placing any rock/sand base. Please include these details on the plan sheet or Perforated Tank detail sheet. 4. I will want to be contacted to inspect the stormwater harvesting system during construction at critical steps(of which I had conveyed/detailed to you in a previous email).
