4 With regard to the MR Multiple Residential development, City Code restricts density to 15 units pr acre and requires a minimum land area of 3,000 square feet per housing unit. The area of the Multiple Residential district is 6.7 acres and 5 12-unit structures meets the minimum density and area requirements. However, there are additional requirements for multi-residential structures that must be met with regard to minimum floor area, maximum lot coverage and off-street parking. The ability to meet those requirements will determine whether or not there is sufficient space for 5 12-unit buildings and that will not be known until the developer submits an application for site plan approval prior to construction of the buildings. Therefore, the five buildings shown in the plat would only serve as a guideline for land use and the City is committed to only allowing the number of buildings that will fit on the Site in accordance with City Code. City COde restricts cul-de-sac lengths to 600 feet. Both cul-de-sacs in the plat are in compliance with City Code. A portion of the plat contains protected wetland #680. A copy of the preliminary plat has been forwarded to DNR for their review and comment. . Existing sewer easements have been added to the preliminary plat as had been requested during Sketch plan review. The location of the sanitary sewer manhole would be well into Lot 21,' and in fact could potentially be within twenty feet of the future dwelling. Although manholes are not accessed frequently, they should be accessed bi-annually for routine cleani~/g. In addition, they need to be available for access to the system in emergencies. Access. to these manholes are protected by easement, which would restrict structures, but normally doesn't restrict landscaping and yard fixtures such as swing sets, etc. Cleaning equipment will cause rutting in lawns, and may be precluded entirely from reaching the manhole by more elaborate landscaping. I suggest aligning the street to keep the manhole within the street right-of-way. The City has not yet received the grading and drainage plans and street profiles as required by City. Code. However, City Staff agreed to receive those plans at the rime the developers request final plat approval. City Staff was of the opinion that until there is sufficient reason to believe the rezoning necessary in this case will be approved, the expense of grading and drainage plans could be delayed. If granted, preliminary plat should be granted contingent upon compliance with this City Staff review letter.
