COMMUNITYGROWTH City Of I N S T I T U T E Pequjott� _ ExivrLr in Small Town Plnrr►tirtg STAFF REPORT Application: Variance to Construct Basement under Dwelling on Non-conforming Lot Applicant: Steve Caouette Agenda Item:3(b) Background Information: The applicant is requesting a variance to construct a basement under the existing dwelling. A variance is needed as the lot is non-conforming due to width at OHW and building line, buildable lot area, and the existing dwelling encroaches into side yard setback. The property is zoned Shoreline Residential and is located on Sibley Lake, a General Development Lake. The lot is 14,405 square feet (20,000 sf required) with 42.6 percent of the lot being impervious surface cover (20% maximum allowed). The dwelling encroaches to within 2.7 feet of the side lot line (10 foot setback required), with the deck encroaching even closer. The dwelling meets the lake setback, but the deck encroaches about 10-feet within the lake setback. The dwelling is 1,136 square feet and the applicant is proposing to construct a walkout basement under the structure. Two retaining walls will extend further into the setback than the existing deck does. No additional impervious coverage is proposed.
