Qansktering the style and size of the residences located within the shore'and district, staff believes that the proposed height limit will create a hardship to ripariari lot owners. Staff suggests that as a trade-off, we continue to maintain the 20 percent limit on impervious surface in most districts versus the 25 percent limit placed by the MnDNR standards. Deck Setback Requirements “he Oty currently allows the construction of a deck to a point six feet into the required setback. This provision was established to address the situation where a home is constructed at the 75 foot lake shore yard setback. As is the case in most instance^ a sliding glass door is installed on the second story. The owner would be allowed, without variance, to construct a six foot deck into the setback area. The MnDNR allows the addition of a deck to a point not exceeding 15 percent of the required sedmek area (onto an existing structures only). In the case where the setback is 75 feet, the deck addition could be 11.25 feet. Staff believes that the City requirement would be more restrictive than the MnDNR standards. 25% or 35% Impervious Surface in R-2 Douglas Reach District The Douglas Beach neighborhood within the City of Minnetrisia is a unique area to Minaetrista, although it is comparable to many neighborhoods in Mound, Orono, Spri Park any other community with older platted developments. Dou^as Beach is a tmt|i aectloa pUlced in the early 1900s with 40 to 60 foot lots. Many of the exisring ynr*round homes are merely converted cabins. In 1982, the City established a new tiffing dassificatlon for Um district (R*«. DB). ^^hin dlls zoning classifkation, the city established new setback regulations, height ffttricrions and impervious surface requirements. In the latter, the Gty amended the coda to aflow up to 25 percent coverage of the lot by structures occupying space above tha pada lavel (including decks, houses or garages). The dty also allowed up to an ypurffiifi 10 percent coverage hy other forms of impervious surface like swimming poo and tt-grade patkit. This provision has signi&antly reduced the number of variance ra^icsts from this neighbortmod. 'f.- i i
