Preliminary Plat and Site Plan Review: Ebony Woods August 31, 2006 Revised: September 22, 2006; December 20, 2006; April 5, 2007; October 4, 2007 Page2of7 3. Mississippi River Overlay District: The property is located in the Mississippi River Overlay District. The City is in the process of updating the regulations in accordance with State rules. Staff has used the draft code to review the proposed subdivision. All developments projects in this District that include platting the property are required to submit a Site Development Plan. However, all multi- family developments are subject to the City's general Site Plan requirement and that Site Plan will satisfy the Site Development Plan requirement in the Overlay District. The District requirements state that the project shall be developed as a Planned Unit Development, shall preserve 50% of the land as open space, and restrict impervious (rooftop and pavement) to 25% of the lot area (or up to 35% with a Conditional Use Permit). It is also noted that the maximum structure height in the Overlay District is 35 feet. This parcel is over 800 feet from the Mississippi River. 4. Lot Size and Dimensions: The proposed twinhome lots are all 40 feet in width with the . exception of Lot 6, which is 44 feet wide. The R -2 Residential District requires 50 -foot lots for twinhomes. A reduced lot width may be permitted as part of the PUD, if approved by the City Council. All proposed lots exceed the minimum lot size for twinhomes of 7,000 square feet. 5. Density: The subject property is approximately 1.1 acres in size. The Medium Density Residential designation allows for 3 -7 units per acre. The sketch plan proposes 6 units which equates to a density of 5.5 units per acre. This density is acceptable if the comprehensive plan amendment and rezoning requests are granted. 6. Setbacks: The R -2 District requires a front yard, side yard, and rear yard setback of 30 feet, 10 feet, and 30 feet respectively. All the proposed'units exceed these requirements. In past reviews of the proposal, the City Council directed you to stagger the buildings in terms of setback from the street. The revised site plan shows the buildings staggered, with the overall building setback roughly doubled from the previous plan. 7. Open Space/Impervious Surface Requirements: The draft Mississippi River . Overlay District regulations require a minimum of 50% open space and a maximum of 25% impervious surface. The current zoning rules allow up to 30% impervious surface. The revised site plan shows 35% impervious surface and 65% green space. In past meetings, the City Council indicated some willingness to allow a higher impervious coverage, to allow the buildings to be staggered and to incorporate more green space. This deviation is permissible through the PUD, if approved by the City Council. 8. Architectural Standards: The R -2: Medium Density Residential district requires the following architectural requirements:
