Reynolds 16365W Arrowhead Lane Birchwood WI 54817 Dear Mr. Reynolds: Notice is hereby given that on August 18, 2006 the Sawyer County Zoning Committee approved with conditions the following application: Part of Lot 3 and all of Lot 4, Indian Beach Park, S 8, T 37N, R 9W, Parcel -9.4. Vol 389 Records Page 153, Doc #320612. 0.464 acres. Property is zoned Residential/Recreational One. Permit is desired for exceeding the 15% impervious surface limit to approximately 20%by the construction of a 16'x28' addition and a 14'x14' storage building. The Town Board has approved the application with provisions. The application has been tabled from the July 21 public hearing. The Sawyer County Zoning Committee approved the application with the conditions that the runoff plan is followed under the guidance of the Sawyer County Land and Water Conservation Department; and the shed be placed on skids over gravel for drainage; and a berm is placed at the starage building; and mowed area is not extended. Applicant is encouraged to keep the trees that are on the shoreline. Findings of Fact of the Zoning Committee: It would not be damaging to the rights of others or property values. It would not be detrimental to ecology, wildlife, wetlands or shorelands. It would not create topographical problems such as runoff, drainage, erosion, flooding, or vegetative cover removal because of Land and Water Conservation supervision. It fits the Town Board recommendation. The approval of the conditional use will expire on August 18, 2007, if application for the actual permit to use/consh-uct is not made by that date. Any person or persons jointly aggrieved by the decision of the Zoning Committee may commence an action with the Sawyer County Board of Appeals to review the decision in whole or in part,within thirty(30)days after the �ling of the decision in the office of the Committee.

Reynolds 16365W Arrowhead Lane Birchwood, WI 54817 Re: Shoreline Vegetation Protection Area (SVPA) Inspection Dear Mr. Reynolds: On September 18, 2006, you applied for a Land Use Permit for construction activities on your property. Section 4.419 MITIGATION REQUIREMENTS, of the Sawyer County Zoning Ordinance requires, that as a condition for the issue of this permit, that you certify the condition of your property's SVPA. The SVPA is defined as, "A strip of land 35 feet wide inland from the ordinary high-water mark of any navigable body of water, including but not limited to: streams, rivers, ponds, flowages and lakes. Term used synonymously with buffer zone, buffer area and buffer strip." You indicated on your permit application that the SVPA did require mitigation. Mitigation is "The requirement to restare shoreline buffer functions that have been lost or adversely affected through development." On October 4, 2006, I visited your property to verify the condition of the SVPA. It is my determination that you are following the intent of the ordinance. Please continue your efforts to maintain/protect the SVPA in accordance with Section 4.410 SHORELINE VEGETATION PROTECTION AREA—copy attached. Please feel free to contact me if you have any questions or concerns.

Box 230 � /�; �..� R1Ge Larie� Wl 54060 VAN GILDER � � ...� 32577 � � RICE LAKE (� �� WIS. �,�/ �ss/ -� �\�\ ONF�1- � Project Number 06553003 July 17,2006 Purpose of Bioretention Device: This bioretention device is intended to enhance st��rm water infiltration, reduce discharge of storm water pollutants, and reduce storm water runoff rates and volumes. This storm water manabement practice is required by Sawyer County due to a home addition project. Design Criteria: Runoff from approximately 0.29 acres will be routed through the proposed bioretention cell through existing and proposed rain gutter/downspouts, subsurface piping, and overland sheet flow. A bioretention cell is proposed for construction due to the clayey nature of the existing soils, in lieu of a less complicated rain garden, which would be compatible with sandy soils. The bioretention cell is approximately five feet deep and 400 square feet in size and is estimated to reduce runoff on an annual basis by approximately 75% and also reduce total suspended solids (TSS) on an annual basis by approximately 80%. TSS removal is a critical component of water quality protection, because suspended soil particles transport pollutaz�ts and nutrients. This design is intended to comply with DNR Conservation Practice Standard 1004, "Bioretention for Infiltration". This document includes important construction considerations for bioretention cells and is enclosed in this report for reference. Erosion Control for Site: Recommended erosion and sediment control practices are indicated on the site plan. Field conditions may require additional practices that may also be required. The site should be stabilized with topsoil, seed, mulch andlor erosion mat as soon as practical. Planting Recommendations: The bioretention site is primarily a sunny location and plants should be � selected to accommodate full sun. One plant is recommended approximately every one square foot. Plants should be native to the area and capable of withstanding water level fluctuations and regional factors including temperature variations. Trees, shrubs, and perennials shall be acceptable for the bioretention cell. Turf grass is not appropriate for the bioretention cell. Once a dense layer of vegetation is established, the mulch layer may be discontinued. Examples of planting lists are included in this report; however, it is recommended that a nursery or master gardener be consulted to develop a planting plan for this site. . �e�i t�-t'l �IJrV"�IY'��. ! u{ E —_ _ __ --_ _ - � •.�_l 01 xJ � _ ri. --- - _— _, Runoff Volume Particulate Sobds PdkAants Output_Summary; Fde Name: G:12006-prq106553003�F1eynoldslReyrwMs.da1 Drainage System and�utfall Output Summary Percent Runoff P�� Runoff Par[iculate Particulate Pmt�Aale y� Runoff Coefficient SolidsCwic.
