• Marshan Townhomes 2nd Addn. page 5 Building materials include vinyl siding, wood shakes in gable ends, and a stone base. Under the current building and fire code, sprinklers are required for all structures of 8500 sf or greater. This includes garage area. All proposed buildings would need sprinklers. * The minimum open space for an urban PUD is 50 %. A memo from the applicant lists the total site area as 176,362 sf, and the impervious area as 88,181 sf. This is exactly 50 %. If the project proceeds, this calculation should be re- checked. The shoreland ordinance sets a maximum of 35% impervious in a shoreland area. The submitted information does not include building heights. It is unlikely that they exceed 36 feet, however. Streets, Access: Access to all buildings would be via private drives off of Aqua Circle. The drives are 24 ft. wide, back of curb to back of curb, with a driving surface width of approximately 22 ft. The Miller's Crossroads project uses these same dimensions for the townhome access drives. The existing Marshan townhomes have wider access drives: 28' with 26' drive surface width. The northernmost access drive would be shared with the existing townhomes on the north side of the site. That drive already exists: it was constructed centered on the property line. A shared driveway agreement is necessary to address this. Utilities, Stormwater Management: The City Engineer's memo is attached. Under PUD requirements, separate public utility services shall be provided to each unit unless exempted by the City Engineer. Where more than one (1) property is served from the same service line, a shut off valve must be located in such a way that each unit's service may be shut off and secured by the City, in addition to the normally supplied shut off at the street. The method of connecting the existing Marshan Townhome units to water has proven problematic and should be improved upon for any new units. The DNR noted in a phone message that water quality may not be adequately addressed • in the stormwater management design. Landscaping: The existing townhomes screen this site from the lake, so screening is not an issue as it might be for lakeshore property. The proposed landscaping is adequate. However, several species should be changed according to the Environmental Specialist's recommendations. ENVIRONMENTAL BOARD The Environmental Board reviewed the application on December 31.d. That board recommended denial of the project because of lack if information on surface water management and the medium density designation. The comments are attached.
