variances approved for additions in the Hunters Park neighborhood; however, past variance approvals are not a basis for current variance reviews. Plan Evaluation 1. R-3 Regulations, Existing Conditions, and Proposed Redevelopment A. Lot Size & Dimensions The lot is 8,712 square feet. Although approved as part of the Hunters Park PUD, the lot does not meet the minimum size requirements in the R-3 Zone. B. Structure Setbacks — Variance required The existing dwelling encroaches as much as 19 feet into the required front yard, eight feet into the rear yard, and three feet Into the northern side yard setbacks. The existing detached garage encroaches into the southern side yard setback as well; however, no changes are proposed to the accessory structure. 1. Minimum Lot Area (sf) 11;000 2. Minimum Lot Size (ft, width/depth) 85/120 3. Height (ft.) 35 4. Lot Covered by Structure 25% 5. Min. Landscape Lot Area 65% 6. Minimum Building Setbacks (ft) Square Feet % Front yard 40 Rear Yard (Principle) 30 Rear Yard (Accessory) 10 Side Yard Interior - Principal (Min/total both yards on lot) 5/15 Side Yard Interior - Accessory 10 Side Yard Corner 40 The proposed addition would remain in line with the existing structure in the rear yard and even step back in the front yard; however, because the existing home encroaches into the setbacks, the addition would do so as well. C. Lot Coverage — Variance Required The existing impervious coverage does not exceed the R-3 coverage limitations. With the proposed addition, the structure coverage would increase to 26 percent of the lot from the current 19.4 percent, which exceeds the 25 percent limit.
