Existing boulevard trees are in place along Town Center Parkway, and will be generally maintained in their current location where feasible. No other existing trees are located on the property. Soil borings had been completed for the property back in 2003, and generally consist of 6" of sandy topsoil over sand below. Groundwater was found ranging from 12-20 feet below the surface. No building constraints related to soil conditions are expected. Proposed Streets: The existing curb cut locations along Town Center Parkway and Village Drive are proposed to be utilized for the intemal private street connections into the proposed development. All private streets are proposed to be 24' back to back wide and located within HOA owned outlots. The existing pedestrian sidewalks along Town Center Parkway and Village Drive will remain in- place, and additional sidewalk will be provided along both sides of Woods Edge Boulevard. Other intemal sidewalks are proposed to ring the common open spaces and provide pedestrian access to the front porches for those homes fronting on the open spaces. Street lighting is provided by a combination of existing street lights supplemented with additional lighting internally and located where necessary. Stormwater Management & Grading: As stated earlier, the "Town Center" development area was mass graded and the required ponding, utilities (including storm sewer), and the perimeter public streets (Village Drive, Woods Edge and Town Center Parkway) were constructed in 2006 in preparation for this development. Our current proposed development is generally consistent with the originally proposed development, with slightly less impervious surface being proposed resulting from the substitution of attached multiple units in place of the proposed 2 -multi -story residential building on the west side of this development. The proposed development's grading has been designed to be generally consistent with the original planned drainage patterns of the site, utilizing the existing stormwater piping system and the 2 stormwater ponds located on the property's east side for all stormwater treatment needs for our project (Outlot C). Additionally, expanded ponding areas have been proposed adjacent to these ponds to provide additional volume (infiltration) & rate control. It is our understanding that the City is in the process of updating the overall "Legacy at Woods Edge" development area's Stormwater Management report to conform to the current design standards of the Rice Creek Watershed District. We will work with the City to incorporate additional stormwater management practices and features that may be required by the watershed. While much of the existing site was rough graded back in 2006, some additional grading is necessary to accommodate the proposed project and townhomes. All grading efforts will match existing grades at the property limits, and incorporates the use of a retaining wall in Block 5 to allow for adequate house construction, sidewalk connections, and added ponding area.
