FILE 07-3293 <br /> August 20,2007 <br /> Page 5 of 5 <br /> and shifting the house north west ten to 20 feet. (The SO'minimum setback shown on <br /> the site plan is actually only required to be 30'as this is a side lot line.) <br /> C. Detail of any Low Impact Developmentl measures proposed to mitigate hardcover in <br /> excess of 25 percent. <br /> Through the use of vegetated swales drainage would be directed away from the <br /> portions of the lakeshore with steep banks (see Exhibit.�. The rain garden proposed <br /> east of the sul-de-sac is for the runoff from the new Bracketts Point Road. It will not <br /> receive any runoff from the proposed house or driveways. <br /> Cleazly the condition of having a 0-75 foot zone on three sides of this lot that comprises 55 <br /> percent of the property reduces the overall allowable hardcover as compared to lots with only <br /> one side abutting the lake. The Planning Commission should determine whether a <br /> reasonably sized home with reasonable amenities and driveways could be developed without <br /> a hardcover variance. In doing this the Commission should discuss each of the relevant <br /> parameters from Section 78-123. <br /> If the Commission determines it would be appropriate to grant a hardcover variance the <br /> Commission should consider if additional Low Impact Development measures to reduce <br /> runoff and/or to improve water quality should be required to compensate for the additional <br /> hardcover. <br /> Are there any other issues or concerns with this application? <br /> Staff Recommendation <br /> If the Planning Commission finds that a hardcover variance would be warranted, Staff <br /> recommends the amount of the variance be reduced by narrowing the driveway and shifting <br /> the house and that the island be a rain garden. <br /> ' Low Impact Development(LID)is an innovative stormwater management approach with a basic <br /> principle that is modeled after nature: manage rainfall at the source.LID uses uniformly distributed <br /> decentralized micro-scale controls.LID's goal is to mimic a site's predevelopment hydrology by using <br /> design techniques that infiltrate,filter,store, evaporate,and detain runoff close to its source. <br /> Techniques aze based on the premise that stormwater management should not be seen as stormwater <br /> - disposal.(http://www.minnehahacreek.org/lid.php) <br />
