Preliminary Plat Review: CBR Development June 1, 2007 Page 2 of 4 Lots 1 and 5 propose a reduced front yard setback to 25 feet. Please revise the plat to reflect the required setbacks. All other setback regulations conform. Architectural Standards: There are no specific architectural requirements for single - family developments. However, elevations have been submitted, and propose to provide single -level homes with two -car garages and front porches. Landscaping: The following comments are offered regarding the landscaping plan, dated April 24, 2007: • A minimum of twenty -five percent (25 %) of the plantings must be conifers (none are shown on the plan). • Trees should be planted at a depth such that the root flare is at finished grade. • Trees should be installed in the front yards of the lots; trees on lots 2 and 3 should be relocated. • Some consideration should be given to additional plantings along County Road 5 to provide some buffering against noise, dust, and headlight glare generated by traffic. A revised landscaping plan must be submitted. Tree Preservation: A tree preservation plan was not submitted and the inventory needs to provide additional information including species, size, condition and whether trees are to be preserved or removed. Also, tree save fencing must be shown on the plan for all trees being preserved. In the field, tree save fencing must be installed at the dripline of individual trees or groups of trees and must be in place prior to any construction activity. Grading and Drainage: A preliminary grading plan has been prepared by Martin Campion of Otto Engineering. Staff has reviewed this plan and offers the following comments: • Topographic contours should be extended 100 feet beyond the boundaries of the plat. • The type, size, invert, and rim elevations of all storm sewers should be added to the grading plan. • A table specifying house type, garage elevation, lowest opening elevation, street centerline grade, and 100 year flood elevation for riparian lots. • Front and back yard slopes must be added to the. plan. • The grading plan should contain normal and 100 year elevation for the ponding area and also emergency overflow elevations showing the overland runoff elevation. • Silt fence should be extended around the entire project grading site. • A trail needs to be incorporated into the grading plan design. This trail is normally required to be within the boundaries of the platted development. • There is not enough detail presented to determine where lots 4 and 5 drain. They appear to drain onto the lots to the east and south. Consideration should be providing yard drains to the ponding area to prevent drainage onto adjacent properties. —274—
