RE: Response Letter #2 for SDP201800040 Hunters Way — Major Site Plan Amendment
Dear David,
Thank you for your review of the major site plan amendment for Hunters Way. This letter contains
responses to County comments dated August 20, 2020.Our responses are as follows:
1. WPO plan/amendment must be approved before site plan amendment is approved.
Acknowledged — WPO2016-52 amendment.
(Rev.2/3/4) Comment still valid.
RESPONSE: Comment acknowledged.
2. (Rev. 1) Provide minimum 3" orifice.
(Rev.2) Not addressed.
(Rev.3) Acknowledged. Engineering recommends a larger orifice because this will become a
maintenance issue.
(Rev.4) This remains an issue and should be addressed with the VSMP plan review.
RESPONSE: Comment received.
3. (Rev.2) Sheet C4 —
a. Callout grate inlet structure type.
(Rev.3) DI-7 no recommended, recommend side inlet. [DSM, pg. 18]
(Rev.4) The details indicate 18-30" dia. riser, but 36" access is called for in the
profiles for the 60" pipe. 2'x2' grate access would seem too narrow an access in
either case. Please use appropriate size for 30" or 36" dia. MH. -Need to confirm
minimum MH access sue.
RESPONSE: The 2'x2' square would be adequate for a person to access through as a
VDOT standard drainage frame has a 22" diameter. The specified riser is 36" and that,
with the grate, will provide adequate access.
4. (Rev.3) Show SWM design table/worksheet.
(Rev.4) Acknowledged. The drainage design will need to be reviewed/approved with the
VSMP prior to FSP approval.
RESPONSE: Comment received.
5. (Rev.4) Cover— Correct the sheet number for Lighting locations
RESPONSE: Comment received. The sheet number for Lighting has been revised.

6. (Rev.4) Sheet C6 — An Ornamental Tree is shown within the SWM easement and will need
to be removed.
RESPONSE: Thank you for directing our attention to this. The ornamental tree has been moved
further away from the easement.
7. (Rev.4) Provide reverse slope bench and/or surface water diversion for 2:1 graded slope at
front of property. {18-30.7.5.C.)
RESPONSE: The above section refers to managed and preserved slopes, however, the slopes on
the property are designated as critical.
