Box 147 Chanhassen. MN 55317 (952)227-1100 NOTARY PUBLIC 2 • Pc 'D030 —0-1 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION (APPROVAL) IN RE: The application of Francisco and Heather Lynn Silva for the installation of a septic system within the required bluff setback, impact zone, and front setback on a property zoned A2 - Planning Case 2020-07. On June 2, 2020, the Chanhassen Planning Commission, acting as the Board of Appeals and Adjustments, met at its regularly scheduled meeting to consider the application. The Planning Commission conducted a public hearing on the proposed variance preceded by published and mailed notice. The Board of Appeals and Adjustments makes the following: FINDINGS OF FACT 1. The property is currently zoned Agricultural Estate District (A2). 2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density. 3. The legal description of the property is: Lot 1, Bluffview Addition 4. Variance Findings —Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The intent of the city's bluff protection ordinance is to ensure that vegetation and soils located near and on bluffs are not distributed in a manner that has the potential to create erosive conditions or otherwise negatively impact the bluff. The configuration of the property and location of the existing home make it impossible to place a septic system on the property outside of the required bluff setback. The applicant has proposed a placement as far as possible from the top of the bluff in order to minimize the impact on the bluff impact zone. Staff believes that the proposed location will have a minimal impact on the integrity of the bluff. The city also requires septic systems to be setback from property lines and road right of ways in order to minimize the potential for these systems to negatively impact adjacent property owners or interfere with the installation of utilities or other features commonly found in right of ways. In this case, the Engineering Department believes that the rockbed SCANNED can be located within the right-of-way without interfering with the function of the right- of-way. Additionally, by granting a variance to the property line setbacks, the required bluff setback variance is minimized and the septic system can be placed further away from the top of the bluff. Granting a variance to allow a single-family home with no ability to hook up to municipal utilities to install a septic system is consistent with the comprehensive plan, and the proposed variance is in harmony with the intent of the zoning code. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: Due to the existence of bluffs on the property, the dimensions of the property, the placement of the house, nature of the contours, and characteristics of the soil, the septic system must be placed in the northwest comer of the property. This placement requires variances from the bluff setbacks, impact zone, and property line setbacks. City sewer and water will not be available for the property in the near future and a functioning septic system is required to have reasonable use of the property c. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The lot is a non -conforming lot of record that was created before the existing district standards, bluff protection, and septic system ordinances were created. e. The variance, if granted, will not alter the essential character of the locality. Finding: Many components of the septic system would be located below grade and would not be expected to have any visual impact on the neighborhood. While the proposal will likely require the removal of several trees within the city's right-of-way, almost half of the other homes along Lakota Lane are easily visible from the road and this would not represent a departure from neighborhood standards. The surrounding residential properties are also located on large lots and are served by septic systems. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 5. The planning report #2020-07, dated June 2, 2020, prepared by MacKenzie Young -Walters, is incorporated herein. 0 • RECOMMENDATION "The Chanhassen Board of Appeals and Adjustments recommends that the City Council approves the placement of the pump line within the 50-foot bluff setback area and the 20-foot bluff impact zone, a 30-foot bluff setback variance for the tanks and a 20-foot bluff and 9-foot property line setback variance for the mound and dispersal area, subject to the conditions of approval: 1. The applicant must apply for and receive all necessary permits from the relevant agencies. 2. The applicant must show proposed erosion control on survey and install erosion control as needed to prevent off -site erosion. 3. The septic system must be located as proposed in the survey and design received by the city on May 1, 2020 as part of the variance request. 4. The property owner shall enter into an Encroachment Agreement with the city for the area of the individual sewage treatment system (septic system) that encroaches into the public easement. The final area of encroachment shall be determined by an as -built survey of the septic system, and the Encroachment Agreement shall be recorded prior to issuance of the Certificate of Compliance. 5. All underground components encroaching into the public easement and identified in the Encroachment Agreement shall be detectable by customary locating equipment (i.e. the installation of tracer wire). The tracer wire shall be tested and approved prior to issuance of the Certificate of Compliance. ADOPTED by the Chanhassen Planning Commission this 2nd day of June, 2020.

Your septic system is designed to kill harmful organisms and remove pollutants before the water is recycled back into our lakes, streams and groundwater. This management plan will identify the operation and maintenance activities necessary to ensure long- term performance of your septic system. Some of these activities must be performed by you, the homeowner. Other tasks must be performed by a licensed septic maintainer or service provider. However, it is YOUR responsibility to make sure all tasks get accomplished in a timely manner. The University of Minnesota's Septic System Owner's Guide contains additional tips and recommendations designed to extend the effective life of your system and save you money over time. Proper septic system design, installation, operation and maintenance means safe and clean water!

Use the chart on page 6 to track your activities. Identify the service intervals recommended by your system designer and your local government. The tank assessment for your system will be the shortest interval of these three intervals. Your pumper/maintainer will determine if your tank needs to be pumped. System Designer: check every 36 months My tank needs to be checked Local Government: check every 36 months State Requirement. check every 36 months every 36 months Seasonally or several times per year o Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. ❑ Surfacing sewage. Regularly check for wet or spongy soil around your soil treatment area. If surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps, call your service professional. Untreated sewage may make humans and animals sick. ❑ Alarms. Alarms signal when there is a problem; contact your maintainer any time the alarm signals. ❑ Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. Consider adding one after washing machine. ❑ Effluent screen. If you do not have one, consider having one added the next time the tank is cleaned. Annually ❑ Water usage rate. A water meter can be used to monitor your average daily water use. Compare your water usage rate to the design flow of your system (listed on the next page). Contact your septic professional if your average daily flow over the course of a month exceeds 70% of the design flow for your system. ❑ Caps. Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or replace damaged caps before winter to help prevent freezing issues. ❑ Water conditioning devices. See Page 5 for a list of devices. When possible, program the recharge frequency based on water demand (gallons) rather than time (days). Recharging too frequently may negatively impact your septic system. ❑ Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any major changes with your pumper/maintainer. During each visit by a pumper/maintainer ❑ Ask if your pumper/maintainer is licensed in Minnesota. ❑ Make sure that your pumper/maintainer services the tank through the manhole. (NOT though a 4" or 6" diameter inspection port.) o Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4.

A riser is recommended if the lid is not accessible from the ground surface. Insulate the riser cover for frost protection. ❑ Liquid level. Check to make sure the tank is not leaking. The liquid level should be level with the bottom of the outlet pipe. (If the water level is below the bottom of the outlet pipe, the tank may not be watertight. if the water level is higher than the bottom of the outlet pipe of the tank, the effluent screen may need cleaning, or there may be ponding in the drainfield.) ❑ Inspection pipes. Replace damaged caps. ❑ Baffles. Check to make sure they are in place and attached, and that inlet/outlet bathes are clear of buildup or obstructions. ❑ Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation. Recommend retrofitted installation if one is not present. ❑ Alarm. Verify that the alarm works. ❑ Scum and sludge. Measure scum and sludge in each compartment of each septic and pump tank, pump if needed. Pump ❑ Pump and controls. Check to make sure the pump and controls are operating correctly. ❑ Pump vault. Check to make sure it is in place; clean per manufacturer recommendations. ❑ Alarm. Verify that the alarm works. ❑ Drainback. Check to make sure it is operating properly. ❑ Event counter or run time. Check to see if there is an event counter or run time log for the pump. If there is one, calculate the water usage rate and compare to the anticipated average daily flow listed on Page 2. Soil Treatment Area ❑ Inspection pipes. Check to make sure they are properly capped. Replace caps that are damaged. ❑ Surfacing ofg{jluent. Check for surfaced effluent or other signs of problems. ❑ Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean as needed. ❑ Ponding. Check for ponding. Excessive ponding in at -grade and mound beds indicates problems.
