Preliminary Plat Review: Sweet Bay Ridge August 2, 2005 :0"6 Lot S~es: The current minimum lot size in the MUSA is 10,800 square feet. All of the lots meet or exceed the minimum size requirement. The lot sizes range from ¼ acre to 2+ acres. The larger parcels include wetland areas and the increase in size is necessary to achieve sufficient upland for development of the lot; the lowlands on a lot are encumbered with drainage and utility easements. Lot Dimensions: It appears that most of the lots meet the 80 foot width requirement at either the road frontage or the building setback line. Lots 9, 10, 11, 18, 45, 46 and 70 have lot widths at the setback line that range from 68 to 78 feet. The preliminary plat must be modified so that all lots are at least 80 feet wide at the building setback line. All of the corner lots meet the 90 foot width requirement. Grading and Drainage Plans: A preliminary grading and drainage plan has been prepared for this subdivision by Passe Engineering, Inc. Staff offers the following comments on this plan: 1. Lot comer elevations need to be provided on all lot comers and along the centerline of drainage swales which do not coincide with common property lines. Drainage and utility easements need to be provided over such swales. 2. A table must be added specifying house type, garage elevation, minimum floor elevation, and lowest opening elevation. 3. On custom graded lots the plan shall indicate the intended path of the overland drainage. In instances where the drainage from one lot must flow over an adjacent lot, critical llot comer or swale grades shall 'be indicated on the plan and the developer must grade these swales as a part of the general plat grading. 4. A temporary cul.de sac needs to be placed on the southern end of Sapphire Street. Lot 75 should be designated as an outlot for this purpose. 5. The maximum slope should not exceed one foot vertical to four fee~ horizontal. Some of the proposed berm slopes exceed this slope. 6. The contours shown between .the street and the house pads appear to be inconsistent. A review of these grades is needed. Calculations need to be submitted showing the pre and post runoff conditions. A permit l?om the Lower Rum River Water Management Organization will be required. Utilities: All lots are proposed to be served by municipal sewer and water. A preliminary utility plan has been prepared which is generally acceptable. Construction plans and specifications subject to review of the City Engineering Department will be.required at the time of final plat. The feasibility for extending municipal sewer and water to the subject property is under consideration by the City Council and must be approved prior to the approval of this plat. 85
