The disturbed area is part of a larger project area for which you have also submitted a special exception application. The property is located on a 2-acre lot within the Real P ~Y Shoreland District of Indigo Pond and another unnamed pond in the Town of Hudson. Staff finds 715 -4677 that the proposed project meets the spirit and intent of the St. Croix County Zoning Ordinance and R ` cling Shoreland District with the following findings: 5-386-4675 1. Filling and grading less than 10,000 square feet in area on slopes less than 25 percent is ;w allowed with a land use permit in the Shoreland District pursuant to Section 17.29(2)(c) of the St. Croix County Zoning Ordinance; 2. The ro osed building site is on slopes of less than 12 percent to approximately 20 percent. i . The proposed driveway appears to bisect slopes ranging from 24 - 30 percent; however, no excavating will occur within this area as part of this land use permit application. According b to Steve West, Landsted, LLC, a temporary driveway of concrete blocks will be laid to provide access for vehicles and heavy equipment used to prepare the building site. Any potential disturbance on slopes of 25 percent or over to install the driveway will need to be addressed as part of the special exception permit and may require an additional variance; 3. The grading limits for the proposed excavated area is more than 465 feet from the OHWM of Indigo Pond and over 320 feet from the OHWM of the other unnamed pond to the east; 4. The erosion control plan features a single row of silt fence around the northwest, west, and southeast boundaries of the grading limits. According to Steve West Landsted LLC storm water runoff from the site will drain to an existing drainage easement located on the southeast corner of the lot and to an existing wetland on Lot 37 to the northwest. A culvert is 2 proposed under the driveway to Lot 36 to ensure that runoff from Lot 35 doesn't flood or wash out the driveway. With conditions for supplementing the silt fence to ensure that sediments don't reach the wetland on Lot 37; maintaining the silt fence and any additional erosion control measures until self-sustaining permanent vegetation is established on all disturbed areas; prohibiting the use of phosphorous fertilizer to establish and maintain a lawn on the disturbed areas, ; and addressing long-term storm water management on the site t as part of the special exception permit; potential negative impacts to the water quality of the ponds and drainage in the area will be minimized; ST-CROIX COUNTY GovERNMENT CENTER ~v 1 10 1 CARM/CHAEL ROAD, HUDSON, W/ 54016 71538&4686 FAX PZCaC0.5A1NT-CR0IX.WI.US WW4V.C0.SAINT-CR0IX.WLUS 1 5. The St. Croix County Land and Water Conservation Department has visited the site and reviewed the plans, and finds the proposed erosion control measures for the initial filling and grading to be done as part of this land use permit application to be adequate; and 6. The Wisconsin Department of Natural Resources has been sent a copy of the application and notified staff that the wetland on Lot 37 is a delineated wetland. The Department has also notified staff that this project is subject to review by the Wisconsin Department of Commerce and that storm water runoff will have to be managed and treated on the site in accordance with NR 151 standards. Based on these findings, approval of this land use permit is subject to the following conditions: 1. The applicants shall contact the Zoning Administrator prior to commencing construction and when the initial phase of construction has been completed. 2. Prior to commencing construction, the applicants shall install the silt fence in accordance with the erosion control plan and shall supplement the silt fence with additional erosion control measures as necessary to ensure that sediments do not reach the wetland on Lot 37. All silt fence and other erosion control measures shall be maintained until permanent, self-sustaining vegetation is successfully established on all disturbed areas of the site. 3. The applicants shall be responsible for submitting storm water plans and calculations for the long-term management and treatment of storm water runoff on the site prior to the Board of Adjustment hearing for the special exception permit. 4. No phosphorous fertilizers shall be used to establish and maintain a lawn on the disturbed areas of the site, unless a soil test confirms that phosphorous is needed. 5. Upon completing the initial site work outlined as part of this land use permit application, the applicants shall submit to the Zoning Administrator photos of the excavated area and erosion control measures as viewed from all angles. This approval does not allow for any additional construction, grading, filling, or clearing of vegetation beyond the limits of this request. Any remaining site work above and beyond the 9,990 square feet identified as part of this land use permit application shall be addressed as part of the special exception permit application and shall be subject to the additional conditions of that permit upon approval by the St. Croix County Board of Adjustment. The project may also require an addendum for an additional variance to disturb slopes of 25 percent and greater to install the driveway.
