This review does not include a review of Erosion & Sediment Control or Stormwater Management. Please adequately address the following comments for preliminary site plan approval: Existing Conditions Information 1) Please label all existing pipes and drainage structures with a unique number for reference. Proposed Plan View Information 1) VDOT approval is required for this project as it affects public right of way. 2) Please label all proposed pipes and drainage structures with a unique number for reference. 3) Please label all entrance and intersection radii. 4) Please include stationing for all proposed public streets at minimum 50' intervals. 5) Please clearly label proposed dumpster and loading areas or comment if none are proposed. 6) 10' wide parking spaces are required for proposed 20' aisles and perpendicular parking per 18- 4.12.16.c.1. Please update proposed parking stall or aisle widths. 7) Parallel parking spaces are required to be a minimum of 9' wide by 20' long per 18- 4.12.16.c.2. The width requirement could be reduced to 7' if approved by VDOT; however 6' width of parallel parking as proposed on sheet 7 is too narrow. 8) Proposed private alley is required to have 12' paved with with F gravel shoulders. Paved shoulders are acceptable; however 12' alley width is too narrow. Engineering Review Comments Page 2 of 3 Please adequately address the following comments for final site plan approval: Application Information 1) Owner is required to provide a completed copy of the standard stormwater maintenance agreement and fee for recordation for any stormwater management facilities. Since this project utilizes an existing retention pond, a reference to or copy of the existing stormwater maintenance agreement would suffice to meet this requirement. 2) Per ZMA2004 -00024 proffer #7, please submit an overlot grading plan showing existing and proposed grading for this project. 3) Prior to final plat approval, a separate set of Water Protection Ordinance plans must be submitted and approved including: stormwater management plan and erosion and sediment control plan. 4) Prior to final plat approval: water protection ordinance — erosion and sediment control and stormwater management and subdivision — road and sewer sewer bonds must be calculated by the county (sewer bond is calculated by ACSA) and paid by owner after receipt of a Bond Request Form from owner. 5) Pro -rated share payment for proposed site which drains to Lickinghole Basin. Existing Plan View Information 1) Please label distances, radii (if applicable) and bearings for existing and proposed property lines on all plan sheets. Proposed Plan View Information 1) Please label entrance for Mornington Court with standard VDOT designation (PE- 1, CG -9a, etc) or provide an equivalent curb transition detail. 2) (for road plans) VDOT Intersection sight distance requirement for a 25 mph public road is 280'. Please revise these distances (it appears 200' is shown). 3) (for road plans) Street trees proposed on sheet 4 appear to conflict with sight distance easement. Please revise proposed planting plans (also see comment 2 above) to remove proposed trees from proposed intersection sight distance easement areas. 4) (for road plans) Please propose a pavement design on typical sections for all proposed public roads which supports proposed traffic loadings per 2009 VDOT Engineering Review Comments Page 3 of 3 Pavement Design Guide for Subdivision and Secondary Roads in Virginia or equivalent. 5) Please label proposed curb type for all proposed public roads and parking lots in plan view. If all proposed road curbs are CG -6 and all other proposed curbs are CG -2, a note stating as much on sheet 3 will suffice (in addition to "TYP" labels shown). 6) (for road plans) Please include landscape plan to ensure no trees are proposed in conflict with drainage or sewer utility lines. 7) (for road plans) Please label street horizontal curve start point, end points, and radii, and proposed tangent bearings for all proposed public streets. 8) (for road plans) Please include proposed stop signs at each intersection and proposed speed limit signs. 9) (for road plans) Please include proposed street name signs at each intersection. Plan Detail Information 1) Please provide a pavement section for the proposed concrete sidewalk per county Design Standard Manual (note strength requirements in plan checklist). 2) (for road plans) Please provide a pavement design which supports typical section pavement types and thicknesses proposed on sheet 7 for Brookley Drive. Types and thicknesses must support proposed traffic loadings per 2009 VDOT Pavement Design Guide for Subdivision and Secondary Roads in Virginia or equivalent. 3) (for road plans) Please include county general construction notes for streets. Street Profiles Drainage Profiles 1) (for street plans) Please include street profiles for all proposed public roads. 2) Please include drainage profiles. Drainage Computations 1) Please include drainage computations. Community Development Engineering is available from 2:30 -4 PM on Thursdays to discuss these review comments.
