RE: Brookhill Blocks 16-17 VSMP Plan (WPO 20210007) Memorandum

The applicant would like to provide a memorandum for the County Engineer's benefit describing a few changes to the submittal of
the subject plan.
The stormwater management facilities located in Block 16, Dry Detention Basin 'A' and Underground Detention System W, were
relocated to avoid impacts to the redefined stream buffer. The new facilities resulted in reduced post -development flows and the
ouffalls remain unchanged.
The revised plan also removed one (1) lot in Block 17, adjacent to proposed Underground Detention System W. This lot's removal
allowed the applicant to realign Underground Detention System W, and to shift the nearby retaining wall and grading outside the
limits of the newly delineated stream buffer. The realignment of Underground Detention System 'B'did not change the system's
layout or volume, and the manufacturer has reissued their approval of this facility, and Underground Detention System W. A
correspondence from Contech Engineering has been provided with this submittal noting their acceptance of the systems.
Please see sheet 16B for block 16's relocated stormwater management facilities, and sheet 17 for block 17's realigned Underground
Detention System W. All other sheets and applicable calculations have been revised to account for these updates.
Sincerely,
Graham Murray, PE
