EROSION CONTROL NARRATIVE

PROJECT DESCRIPTION

THIS PROJECT IS LOCATED IN THE LAKEMONT NEIGHBORHOOD IN THE CITY OF PETERSBURG AND

EXTENDS ALONG NASH STREET. THE PURPOSE OF THIS PROJECT IS TO PROVIDE WATER QUALITY

TREATMENT WITH THE CONSTRUCTION OF A DRY SWALE RETROFIT ALONG NASH ST. PROJECT EXTENTS

TERMINATE AT SOUTH WHITEHILL AVE, EAST OF THE INTERSECTION OF NASH STREET, WHERE THE

PROPOSED SWALE WILL TIE BACK IN TO THE EXISTING STORM SEWER. THE TOTAL DISTURBED AREA

WITHIN THIS PROJECT IS 0.09 AC.

EXISTING SITE CONDITIONS

THE PROJECT SITE IS LOCATED WITHIN THE CITY OF PETERSBURG RIGHT-OF-WAY. LAND COVER WITHIN

THE SITE CONSISTS OF ASPHALT PAVEMENT, MANAGED GRASS AREAS, AND DRIVEWAY CONNECTIONS TO

THE ROADWAY. EXISTING TOPOGRAPHY WITHIN THE SITE IS CHARACTERIZED WITH FLAT SLOPES AND

WITH LONGITUDINAL SLOPES OF LESS THAN 0.5%. DRAINAGE FROM THE ROADWAY IS COLLECTED WITHIN

A STORM DRAIN SYSTEM AND WITHIN ROADSIDE SWALES.

ADJACENT AREAS

TEMPORARY CONSTRUCTION EASEMENT WILL BE REQUIRED ON PARCEL IDs 004290011 AND 004290001.

THE SURROUNDING PROPERTY FOR THE PROJECT IS RESIDENTIAL LAND, RESIDENTIAL STRUCTURES, AND

ROADS.

OFF-SITE AREAS

ANY OFF-SITE LAND-DISTURBING ACTIVITY ASSOCIATED WITH THE PROJECT MUST HAVE AN APPROVED

ESC PLAN. CONTRACTOR SHALL PROVIDE DOCUMENTATION OF THE APPROVED ESC PLAN FOR EACH

OFF-SITE LAND-DISTURBING ACTIVITY.

SOILS

ALL SOILS WITHIN THE PROJECT SITE AND CONTRIBUTING DRAINAGE AREA ARE CLASSIFIED AS FOLLOWS:

MAP UNIT: 7B

EMPORIA-URBAN LAND COMPLEX, 0 TO 6 PERCENT SLOPES, HYDROLOGIC SOIL GROUP C. EMPORIA SOILS

HAVE A USDA TEXTURE OF SANDY LOAM, ARE WELL DRAINED, PERMEABILITY IS MODERATELY SLOW TO

SLOW, AND SURFACE RUNOFF INDEX IS MEDIUM TO HIGH.

MAP UNIT: 20

UDORTHENTS, 0 TO 25 PERCENT SLOPES. HYDROLOGIC SOIL GROUP C. UDORTHENT SOILS ARE

MODERATELY WELL DRAINED. SHRINK SWELL POTENTIAL IS LOW. THIS SOIL IS NOT FLOODED. IT IS NOT

PONDED. THERE IS NO ZONE OF WATER SATURATION WITHIN A DEPTH OF 72 INCHES.

CRITICAL AREAS

THERE ARE NO IDENTIFIED ONSITE CRITICAL AREAS. HOWEVER, THE ULTIMATE OUTFALL FOR THE

STORMWATER CONVEYANCE SYSTEM IS HARRISON CREEK (IMPAIRED WATERWAY), EAST OF THE PROJECT

SITE. THERE ARE ALSO DELINEATED WETLAND AREAS SOUTH OF THE NEIGHBORHOOD. PROJECT IS

LOCATED WITHIN REGULATED CHESAPEAKE BAY PRESERVATION AREA (REGULATED URBAN AREA).

MAINTENANCE OF EROSION AND SEDIMENT CONTROL MEASURES IS CRITICAL FOR PREVENTING THE

DISCHARGE OF SEDIMENT TO THESE AREAS.

EROSION AND SEDIMENT CONTROL MEASURES

UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL

PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND

STORMWATER MANAGEMENT CONSIDERATIONS

THE PROJECT WILL NOT INCREASE PEAK RUNOFF RATES. THE PROJECT INCLUDES DRY SWALE

CONSTRUCTION. THE PURPOSE OF THE DRY SWALE IS TO PROVIDE WATER QUALITY IMPROVEMENT AND

TO PROMOTE INFILTRATION. THIS PROJECT MEETS CONDITIONS OUTLINED IN 9VAC25-870-76 AND VA DEQ

GUIDANCE MEMO NO. 15-2003 AND IS THEREFORE NOT SUBJECT TO VSMP REGULATIONS.

OF A TEN-YEAR FREQUENCY STORM TO VERIFY THAT STORMWATER WILL NOT OVERTOP ITS

BANKS AND BY THE USE OF A TWO-YEAR STORM TO DEMONSTRATE THAT STORMWATER WILL

NOT CAUSE EROSION OF CHANNEL BED OR BANKS; AND

(c) PIPES AND STORM SEWER SYSTEMS SHALL BE ANALYZED BY THE USE OF A TEN-YEAR

FREQUENCY STORM TO VERIFY THAT STORMWATER WILL BE CONTAINED WITHIN THE PIPE
