R-2 Residential District standards were used to review the proposal. The permitted density in the R- 2 Residential District is 3-7 units per acre. The preliminary plat proposes 6 units on 1.1 acres, resulting in a density of 5.5 units per acre. 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 rednced lot width may be permitted as part of the PUD, if approved by the City_ All proposed lots exceed the minimum lot size for twinhomes of 7,000 square feet. 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 meet these requirements. The property is located in the Mississippi River Overlay District, but is located over 800 feet from the river itself. The City is in the process of updating the regulations in accordance with State rules. 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 surface (rooftop and pavement) to 25% of the lot area (or up to 35% with a Conditional Use Permit). The site plan shows 71% open space in the yard areas for the twinhome units, resulting in 29% impervious surface. As the Overlay District requirements are not yet effective, staff feels the submitted plat meets the intent of the open space and impervious surface requirements. It should be noted that current river regulations limit impervious surface to 30%, which the plan meets. The development will receive public access from Ebony Street, a dedicated and improved public street. Each unit will have its own driveway access onto Ebony Street, which is acceptable to staff. Some revisions are required to the grading and drainage plan. A permit is required from the Lower Rum River Water Management Organization. - Some minor changes are required to the landscaping plan. Density transitioning is require~ along the eastern boundary of the site. Existing vegetation within the tree preservation area appears to satisfy the transitioning requirement. The lot to the south, Lot 1 Block 1 Clemens 2nd Add, is currently vacant. City Code does not require density transitioning measures when a proposed residential development is adjacent to a vacant parcel. However, that lot was just recently created (received final plat approval in November of2005) with the intent of constructing a single family home on the lot. If the City Council wishes to require additional landscaping along the southern property line, some revisions to the site plan and/or plat may be necessary. -The R~2:Nre-diUin Density Resideiltia:raismcrhas-SiYme-s"}fecific--architecturaI-requirements;- which -- are reviewed in the staff review letter. The applicant has stated that each building will be a different earth-tone color, and all will meet the 35% brick requirement. Color and brick percentage will be verified at building pennit review. The applicant has submitted several revised color building elevations, which are included in a separate packet from the agenda. The submitted elevations meet the R-2 District requirements. The Council most recently reviewed this case at the March 20, 2007 work session, and directed tlle applicant to prepare additional revisions to the building elevations, which are marked as "5th Submittal""in your packet. The revised elevations show some additional landscaping around the entrances and between the garages. The units appear to be offset a bit within the building, and the buildings themselves are staggered a bit. This is difficult to verify without a revised site plan; if this proposal moves forward, these revisions would need to be reflected on the final plat submittal. The latest elevations show different color shingles being used between each unit, which staff would -84-
