L3.10, Tree Planting Plan: Please show C5.1 (Grading Spot Shots Plan) storm lines as light linework (no
need to show elevations, or grade) on L3.10 to evaluate for landscape conflicts. 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.

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.

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.
3. 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.)
4. 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, WPO201800078
Amendment, and plat at deed bk.-pg 5198/669-670. Note: storm lines below SWM facilities require a
public drainage easement. Easement plat application:

5. Provide defined storm conveyance and typ. detail for ditch /swale on east side of downslope access to Spa.
6.
Recommend bypass for SWM3 should infrequent event overwhelm the underground facility, or obstruction
at weir plate prevent SWM3 design discharge via storm pipe 109. A possible option: locate a relief pipe
that connects SWM3 with Str. 108; image, below:
