CASE 125-83 Page 2 floodplain zoning maps. The application as proposed requires the alteration of a wetland. In addition, 100 percent of the 100 foot buffer area is proposed to be altered. Exhibits A and B show the location of the proposed buildings as they relate to the wetland, buffer area, and floodplain. Note that• the buildings lie entirely within the wetland buffer area. The driveway and parking area does encroach upon the wetland itself. The main dwelling building and parking area encroach upon the floodplain area. 3) The Dwelling building has proposed setbacks of 20 feet from the: front property line and 10 feet from the side property line. Code requires a 30 foot front yard setback and 20 foot side ylsd setback. Section 48.08 of the Wetlands Zoning Ordinance pro- vides for development density intensification by providing credits for the undevelopable portion of wetlands. This allows the possibility that setbacks may be decreased to facilitate preservation of the wetland area and also allow development to occur on developable portions of properties. 4) The applicant is proposing to provide some of his stormwater storage on the parking lot. The wetland area itself is intended to be used as the stormwater storage area for the remainder of the water to be stored for the proposed development. According to Attorney Meyers, wetlands can be used to detain water provided silt, debris and pollutants are skimmed off prior to the water entering the wetland. Most, but not all of the stormwater leaving / the site will pass through the proposed skimmer. Stormwater gener- ated behind the garages and in the area west of the parking lot will be directed to the wetland without passing through the skimmer/runoff detainer. 5) Also according to Attorney Meyers, the Wetland Ordinance does not prohibit development in wetlands. The Ordinance states that a wetland alteration permit must be obtained prior to any filling, excavation, hardcover, structure, etc. taking place on the property. If the proposed developments meets the standards as stated in the Ordinance, development of wetlands may be allowed to occur. 6) Exhibit C shows the placement of a typical 1,000 square foot single family home on the wetland map. Even with the minimum type of development (a single family home), encroachment into the wetland buffer area is still required. In other words, the wetland buffer area covers such a large percentage of the property, that any type of development would encroach upon the buffer area. Open Space Requirements: 1) With the adjusting of the parking area to meet the 9� foot space requirement, and using all of the available non -wetland area, the open space requirement of 625 square feet per unit (6,250 square feet total) will be met.
