C. Stormwater Management Plan(SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or
disapprove a SWMP. This plan is disapproved, and the reasons are provided in the
comments below. The stormwater management plan content requirements can be
found in County Code section 17-403.
1. Comment: Please add an Existing Site Condition page to help facilitate
approval. VRRM spread sheet (sheet 14 of 24) could not be adequately
verified.
Response: Existing conditions sheets have been included with this set of plans.
2. Comment: Please submit information on "Existing" SWM Basin. No records
found for basin other than decorative in nature. Does not have a SWM
Identification number in data base.
Response: Pond will be labeled as such. No SWM credit has been taken for the
pond.
D. Erosion and Sediment Control Plan(ESCP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or
disapprove an ESCP. This plan is disapproved, and the reasons are provided in the
comments below. The erosion control plan content requirements can be found in
County Code section 17-402.
1. Comment: Silt fence running down slope behind the 5 proposed houses acts
more as a diversion than filter fabric and will require a catchment structure at
the bottom of the line to prevent overloading and failure to contain sediment.
Please show a diversion and sediment trap in place of silt fence.
Response: Silt fence has been added to control the flow of stormwater behind the
buildings.
2. Comment: There may be a gas line buried along the top of slope behind the
houses. Please make sure no conflicts will occur with existing utilities in the
area. All existing utilities need to be shown.
Response: Existing utilities are shown based on utility locating equipment. Owner
will verify location of gas line prior to construction.

3. Comment: Sediment trap with diversions should be added to sheet C-19 next
to construction entrance. Please clarify what is occurring in this area. Aerial
photography shows dwellings in that area.
Response: Additional silt fence has been added per our discussion.
4. Comment: Please add an "existing site conditions" page to the submittal.
Existing site conditions page should show what is to be demolished prior to
construction of project.
Response: Existing conditions sheets have been included with this set of plans.
5. Comment: Curb inlet sediment filter shown on page 21 of 24 is not
recommended due to lack of overflow capacity. Please show the "Block and
Gravel Curb Inlet Sediment Filter",Plate 3.07-8 on page 1I1-45 of the VESCH.
Response: The inlet protection has been added.
We trust that the above responses and revised plans properly address the outstanding
items. If you have any questions, please contact me.
Sincerely,
WW Associates, Inc.
