Trees should not occupy private drainage corridors, or be shown within 5' of private storm drain centerline (CL). For pipes within public drainage easements (i.e., downstream of SWM facilities), trees may not be located within public drainage easements. Understory plants should be located > 5' from CL of public drainage easements. Locating plants within a public drainage easement carries risk (plant removal /loss). Please ref. deed of dedication of public drainage easement for proscriptive language. Review areas circled in blue, below. (Rev. 1) Addressed. As follow-up: See Planning comment, d. 4/28/20: `2. [18-4.11] Structures and easements: REV 2: Proposed tree near end of parking area appears to be conflicting with proposed waterline.'

Engineering Review Comments Page 2 of 5 N 4. PROPOSED SPA ` 1 axon o- rEp ' Engineering Review Comments Page 3 of 5 r Please consider and respond to VSMP /WPO Amendment review comments, d. 15 Jan 2020. Note: A closer reading of 17-603.C., and definition of water -dependent facility (17-205) indicates that storm sewer is authorized in a stream buffer, meaning: 1) mitigation of stream buffer impact associated with storm pipe is not required, and 2) storm pipe may be located within the 50-streamward feet of a stream buffer. Please disregard 15 Jan 2020 Engineering plan review comment 7, which does not accurately state requirements. (Rev. 1) Addressed. Applicant response: `Outfall has been revised to ensure that pipe and riprap are contained within the first 50' of the buffer.' Water -dependent facility. The term "water -dependent facility" means a development that cannot exist outside of the stream buffer and must be located on the shoreline because of the intrinsic nature of its operation and which include, but are not limited to: (i) the intake and outfall structures of power plants, sewage treatment plants, water treatment plants, and storm sewers; (ii) public water -oriented recreation areas; and (iii) boat docks and ramps. C6.2, LD-347: Please review inlets 118, 120, 122, 126. Check pipe dia. v. outlet water surface elevation, and revise to ensure non -pressurized flow within capacity of pipe. (Increase pipe diameter, as needed.) (Rev. 1) Addressed. As follow-up: Please review C6.2 content since virtually no information displays. Engineering checked initial comment against WP0201800078 to confirm addressed, but C6.2 Minor Site Plan Amendment should include data shown on C6.2 included with WP0201800078 Plan, Amendment 1. (LD-229, LD-347 tables (include tables on Site Plan Amendment); pre- /post -developed CN reduction data (option: may include or remove all VRRM.xls data /text).) C6.6: Show existing public drainage and SWM facility easements. Provide label ref, to deed bk.-pg., Ex. easements: 5198/669-670). Note: Submit easement plat consistent with SDP2020-00002, WP0201800078 Amendment, and plat at deed bk.-pg 5198/669-670. Note: storm lines below SWM facilities require a public drainage easement. (Rev. 1) Partially addressed. Applicant response: `Existing public drainage easements have been added.' Asefollow-up: Please submit easement plat with application consistent with WPO Amendment 1. Note: storm lines below SWM facilities require a public drainage easement. Applicant response to WP0201800078 Amendment 1, item #12: `Timmons Group is currently working to amend the previously recorded easement plat. Plat submission to follow soon.' Asefollow-up: See Planning comment, 4/28/20: ` L [ 18-32.7.4.2 and 18-32.7.5.3] Easement Plats: An easement plat is required for the proposed SWM facilities management easement. An easement plat was previously approved for this easement, however the dimensions and design have changed. Comment persists.' As follow-up follow-u_ fp to Planning comment #1: Provide bk.-pg. reference label to recorded new easement plat on C6.6, (similar to label for Ex. easements, see below) to ensure easement is recorded. Approved WPO 201800078 Amendment 1 permits grading consistent with the Approved amended WPO Plan —recording new public drainage and (revised) SWM Facility easements (plat) corresponding with WP0201800078 Amendment 1 is essential.

C4.0: Revise 3' sidewalk to 5' width, Min. (Rev. 1) Comment persists. Applicant response: `Sidewalks have been revised to 5' minimum. Sidewalk from the eastern parking facility to the building has been shown as 4' to match VSMP comment #6.' VSMP request for 4' Min. width was in error. Although VSMP /WPO 201800078 Amendment 1 is approved (5/6/20) without request to revise walk width to 5', the initial review comment on Minor Site Plan Amendment is consistent with ordinance and review guidelines. Please revise 4' sidewalk to 5' width (no need to revise VSMP /WPO) and send .PDF of C4.0 and C6.2 for preview against Engineering items 3, 7 / Planning #2. Engineering will recommend Minor Amendment approval once .PDFs reviewed, pending easement plat recordation (Planning #1, Engineering item 4). (Engineering anticipates Minor Amendment will be combined with VSMP /WPO plan sheets as a construction plan set, that this set will indicate all walks > 5' wide. ESC inspectors do not evaluate walk width. There should be no issue if WP0201800078 shows 4' sidewalk. We received a digital WPO plan, have requested 2 print copies of the WPO plan, have uploaded approved WPO Amendment 1 to CV, and anticipate no issues during construction if construction plans show 5' walk width. I regret review error.) 8. C0.0: Recommend title sheet include ref. to SDP2020-00002. (Rev. 1) Addressed.
