Engineering has reviewed the initial site plan and offers these review comments. Given relative extent of comments,
Engineering recommends against initial site plan approval.
C4:
1. Tiered wall height along north parcel boundary exceeds max. wall height (6') for retaining walls
constructed on managed steep slopes [18-30.7.5.A.1.]
2. Offsite grading proposes to erase an existing natural drainage feature that conveys off -site runoff from U.S.
Rt. 250 and largely impervious development east of Overlook Hotel. Photos of natural drainage are
available.
3. Initial site plan proposes extensive off -site grading on TMP 78-13A, without, to our knowledge,
preliminary assurance that off -site permanent grading easement can be obtained. Engineering recommends
against approval of initial site plan without preliminary written assurance that a permanent off -site grading
easement may be obtained, since this design relies on off -site grading.
4. Revise ISP to avoid drop inlet /storm pipe - retaining wall conflict (highest tiered wall north of hotel).
5. ISP proposes to discharge runoff via 15" CMP to an existing 20' drainage easement (DB 2456 PG 689),
which is the existing natural drainage way mentioned elsewhere. ISP must provide at least initial data
concerning carrying capacity of the existing natural drainage way relative to additional runoff from
Overlook Hotel, given that proposed design appears to entirely obscure the drainage way.
6. Provide transit across TMP 78-13A for runoff from U.S. 250 and points east that currently transits via
existing natural drainage way.
7. Tiered retaining walls south of hotel (if rely on geogrid) require permanent maintenance /access easement
since geogrid will extend onto TMP 78-73131. Similar to permanent off -site grading, initial site plan should
famish evidence of preliminary approval with property owner to the south that a permanent access /wall
maintenance easement is likely to be obtained by Overlook Hotel development.
8. Storm lines downstream of SWM facilities are within public drainage easement. Engineering does not
accept storm lines within public drainage easement that cross retaining walls, revise to avoid storm lines
within public drainage easement that cross retaining walls.
9. Obtain private sanitary easement across TMP 78-13A.

C3:
10. Dumpster appears inaccessible to waste management vehicles. Provide auto -turn using wheelbase for
typical waste management vehicle that would likely service the property, to show that design alignment is
not problematic.
11. Provide bumper blocks for 14 parking spaces fronting retaining wall south of hotel.
12. Provide guardrail for all parking spaces that front north or west edge of parking lot on hotel site, since these
parking spaces front tiered retaining walls with vertical drop intervals ranging 14 to nearly 30 feet in
height.
C2:
13. Show, depict, label any existing easements on TW 78-73A7, Overlook Hotel development parcel.
14. Tree conservation area and Landscape Easement appear in conflicts with proposed development, clarify
how development is to occur given likely limits imposed by tree conservation area and landscape
easements.
Cl:
15. LiDAR data may not be used to design physical improvements (retaining walls, for example), unless sealed
by a licensed surveyor. Provide LS-seal for design of any physical improvements that rely on LiDAR data.
General
16. Submit WPO plan at earliest convenience. WPO plan approval is required prior to final site plan approval.
17. Revise ISP to indicate type of underground (water quality) treatment system that may be utilized. A range
of options exist, but `underground storrnwater treatment and detention structures' label lacks even
conceptual specificity. It is unclear whether or how this development will meet storm runoff water quality
or quantity requirements, especially as it appears this development will be required to meet energy balance
at point
