According to the site plan and narrative, the proposed project consists of construction of a 24' x 24' accessory structure outside the 40-foot bluffline setback with associated grading that will involve a total of 600 sq. ft. of land disturbance. Staff finds that the proposed activities meet the St. Croix County Zoning Ordinance and the Lower St. Croix Riverway District based on the following findings: 1. The property consists of an existing principal, structure located at 333 N. Cove Rd., Lot 8 of Bomar Hts. 1 st Addition subdivision plat, is zoned Ag/Residential, and is located in the Rural Residential Management Zone of the Lower St. Croix Riverway District; 2. The proposed accessory structure is more than 200 feet from the OHWM of the St. Croix River, greater than 25' from any property line, and is greater than 40 feet from any blufflines pursuant to requirements in Section 17.36.G.5.c.a); 3. The proposed building construction will result in approximately 600 sq. ft. of land disturbance that will not affect slope preservation zones or encroach into the f -a bluffline setback, and per building specifications submitted by the applicant's agent, the roof will not exceed the maximum height of 35 feet; 4. The proposed structure will be approximately 14.5' in height according to construction drawings. With conditions that the structure does not protrude above x<; 'y the bluffline as viewed from near mid-river, that windows and building materials on the structure utilize earth-tone colors and non-reflective surfaces, and the structure is visually inconspicuous, this project will meet standards in Sections17.36 G.5.c.2)a) and 17.36 H.1 with regard to being visually r in, co - . i uous; ro. 1 Sr. CRO1X COUNTY GOVERNMENT CENTER 110 1 CARMICHAEL ROAD, HUDSON, W1 54016 715386-4686 FAX PZ@CO.

The applicant proposes to manage stormwater runoff from the new impervious roof surface via two 24' long by 1' wide rock infiltration trenches alongside the accessory structure; i 6. The Town of Troy has reviewed the project for their Riverway permit and the their building inspector will review the submitted plans and land use permit prior to issuance of a building permit; 7. Steve Olson, Land & Water Conservation Dept., reviewed the application and found the proposed trenches were sized using 72 square feet, not 72 cubic feet, so the rock trenches with 30% void space only provides 7 cubic feet of storage volume. However, the 48 square foot area of rock trench will be adequate assuming the soils will infiltrate at a minimum of 0.5 inches per hour. With conditions to have sandy soil underneath the rock trenches, the LWCD will have no objection to the proposed project; 8. Mike Wenholz of the Wisconsin Department of Natural Resources has reviewed the application and is in support of the project due to its conformity with ordinances; 9„ A site plan prepared by the applicant indicates the location of the proposed garage, which is not on a riparian lot and there is no surface water drainage toward the river; 10. If constructed as proposed, this project will meet the spirit and intent of the Lower St. Croix Riverway District. It will not degrade the scenic, recreational, or natural values of the St. Croix River Valley, nor will it negatively affect the public health, safety and welfare of County residents.
