STORMWATER MANAGEMENT PLAN
B-4963, WBS No 40241 1 1
ROCKINGHAM COUNTY
Hydraulics Project Manager Stephen R Morgan PE
Date 10/17/2012
ROADWAY DESCRIPTION
The project involves the replacement of bridge number 32 over Jacobs Creek on SR 2361
(New Lebanon Church Road) in Rockingham County The overall length of the project
is 0 133 mile The project will replace an existing 100 foot length bndge with a new 2 @
12 (W) X 11 (H)reinforced concrete box culvert (RCBC)burred 1 below the
streambed An off site detour will be required
ENVIRONMENTAL DESCRIPTION
The project is located within the Roanoke River The proposed bndge is over Jacobs
Creek which is classified as C
Approximately 0 03 acre (76 feet) of surface water will be permanently impacted due to
the culvert Approximately 71 feet of stream will be impacted due to bank stabilization
Approximately 0 01 acre(15 feet) of stream will be temporarily impacted due to
construction(use of impervious dikes)
BEST MANAGEMENT PRACTICES AND MAJOR STRUCTURES
Best Management Practices(BMPs) and measures used in the project are non-structural
and are an attempt to reduce the storm water impacts to the receiving stream due to
erosion and runoff as well as attenuate and disperse storm water before entering the
receiving waters There is no direct discharge into the receiving water
CULVERT
L STA 16+10 18
Replace existing bridge over Jacobs Creek with double barrel culvert(2 @l2 Wxl 1 H)
A 2 sill is used at the entrance to restrict low flow to one barrel to prevent over-widening
of the stream near the culvert The culvert is buried 1 below the natural streambed
Therefore the 2' sill at the entrance has an effective height of 1' Bank stabilization using
class I rip rap is used at the inlet and outlet side of the culvert Floodplain benching using
class I rip rap is also used on the high flow barrel of the culvert The bench is 1 above
the streambed The construction sequence of the culvert calls for using impervious dikes
and a stilling basin There are temporary impacts in the stream due to the use of
impervious dikes in the stream during construction
