Hilbert, Hans From: Hilbert, Hans Sent: Tuesday,January 31, 2017 2:02 PM To: 'aaron @martenbuilding.com' Subject: FW: 2806 Willow Court Attachments: 20161111115721.pdf Aaron, I've attached the certified survey map for the property you're interested in which I have marked up to show some of the constraints on this property. All of the measurements I made on the survey should be considered estimates and accurate measurements and calculations will need to be provided by a licensed surveyor at the time of permit application. The setbacks are as follows: Front setback from Willow Ct ROW=20 feet Side yard setback= 10 feet, each side Wetland setback from south side of Tower Dr pavement and east side of Crescent Dr pavement= 100 ft(Dane county enforces a 75 foot setback,the Town of Dunn enforces a 100 foot setback). Please note there are also delineated wetlands less than 2 acres in size on the property, uses are extremely limited in these areas and no structures may be located within them. I've indicated the wetland regulated areas in pink shading. These lots are also within 300 feet of Lake Waubesa,these portions of the lots are within the shoreland district. Within the shoreland district we regulate impervious surfaces including driveways, structures,walkways, and basically anything that is not vegetation. For lot 1 the shoreland area is indicated with blue shading. You can have up to 15%of impervious surface within this area. If you do stormwater management in the from of a shoreland mitigation plan you can increase the limit to 30%within the blue shaded area. Amounts over 30% may be allowed by performing additional stormwater management, however given the depth to groundwater for this area it is unlikely that you could meet the requirements. The portion of the lot that is beyond 300 feet from Lake Waubesa is not regulated for impervious surfaces. There is also mapped floodplain in the area. A topographic survey will be required to show that any proposed structures conform to floodplain regulations. Even if the development is located outside of the floodplain we strongly encourage you to design the development meet or exceed the flood protection elevation and provide lands elevated above the floodplain around structures. When the property was rezoned the owner entered into a restrictive agreement with the Town. I will forward you that agreement in a separate e-mail. You should also be in contact with the Town of Dunn, as they may have additional regulations that must be met in order to obtain a building permit. Please let me know if you have additional questions. Hans 1
