File #2340 February 3,1998 Page 6 100' width standard. In staffs opinion the code does not in any way support nor allow the creation of lake access for the proposed duplex lot. If this had been proposed as a PRD, the Shoreland ordinances note that "the allowable number of dock slips or moorings in the designation of which dwelling units or sites will have the right to use those slips or moorings shall be subject to Council approval and shall be defined in the covenants governing the PRD. In no case shall the number of slips or moorings exceed the number of allowed under the official controls of the Lake Minnetonka Conservation District. All docks serving three or more dwelling units shall be subject to the joint use dock licensing requirements in Chapter 5 of the Orono Municipal Code". However, applicant is not proposing this as a PRD and therefore it would be inconsistent with past City practice and policy to allow non-riparian lots to gain lake access at a density greater than one dwelling unit per minimum lot width increment of the Zoning District. Notwithstanding the above general discussion, applicant has noted that providing a single slip for each of the three dwelling units on the property, would perhaps have less impact than the possibly four slips that might be created to serve just the lakeshore lot. It is staffs understanding that a four slip dock would generally be allowed by LMCD on this site, as long as all four boats were licensed to the ovMier/occupant of the lakeshore lot. Stormwater Ponding The City normally excludes the area of required stormwater ponding from the area calculation of individual lots, per Subdivision Code Section 11.41, Subdivision B (4). The current proposal has just the bare minimum acreage in each of the two lots, and creation of stormwater ponding and the subsequent exclusion of the pond area from lot area calculations, will result in the need for lot area variances. The MCWD has indicated the site is small enough to be exempt from their ponding requirements. Since applicant has not submitted a grading and drainage plan nor plans for stormwater ponds, the impact of such facilities remains to be seen. However, it is likely that a lot area variance could be needed once such facilities are defined. The topography of the site indicates that most of the runoff from the private road and new homes would be to Maxwell Bay. This is also true of the runoff from the other homes to the east. A joint pond might be possible someday. Of greater concern is the runoff from the nearby marinas which are in the 90% hardcover range and which have no ponding facilities currently.
