This list was compiled from the Piedmont Virginia Native Plant Database found on the Albemarle County website (http://www.aIbemarle.org/nativeplants/Iist.asp?ShowAlI=ALL). Additional plants not on this list may be used for buffer plantings if slope, aspect, soil type and hydrologic conditions are appropriate for the plant species. Only native plants will be specified for plantings in the stream buffers shown on the plans.

FT DUE TO THE ADDITION OF THE NEW FORESTED AREAS PROVIDED AS PART OF THE STREAM MITIGATION, THE POST DEVELOPED CURVE NUMBER REMAINS THE SAME AS THAT CALCULATED FOR THE PRE DEVELOPED CONDITION. SINCE THE OVERALL NATURE OF THE TOPOGRAPHY HAS NOT BEEN CHANGED, THE TIME OF CONCENTRATION WAS NOT AFFECTED. THEREFORE THE CALCULATED RUNOFF FROM THE SITE IS THE SAME IN THE PRE AND POST DEVELOPED CONDITION AND THE SITE MEETS THE REQUIREMENTS SET FORTH IN MS -19. (SEE HYDROGRAPH REPORTS THIS SHEET.) STORMWATER MANAGEMENT QUALITY CONTROL NARRATIVE 19,362 SQUARE FEET OF NEW IMPERVIOUS SURFACE (CART PATH) IS BEING GENERATED BY THIS PROJECT. STORMWATER QUALITY WILL BE PROVIDED WITH SHEET FLOW OF 0.32 ACRES OF NEW OR EXISTING IMPERVIOUS SURFACE (CART PATH) AND 6.32 ACRES OF TURF DIRECTED TO NEW AND EXISTING FORESTED STREAM BUFFER AREAS. THE REMAINING CART PATHS NOT DRAINING TO THE STREAM BUFFERS HAVE BEEN TREATED AS A SIMPLE DISCONNECT TO A/B SOILS. (SEE DWG. C-18 FOR DRAINAGE AREAS TO THE STREAM BUFFERS AND THE VRRM WORKSHEET PROVIDED ON THIS SHEET.) THE LIMITS OF CLEARING AND GRADING WERE USED FOR THE BMP ANALYSIS AREA.
