Memorandum
To: Christopher Perez, Planning
From: Justin Deel, Engineering
Date: 4 December 2015
Subject: Sunset Overlook Initial Site Plan (SDP201500055)
The initial site plan for Sunset Overlook has been reviewed. The following concerns should be addressed;
1. Slopes within the preserved slopes overlay district that are proven to be less than 25% based on
new topographic information do not become managed slopes, as indicated by the "existing
managed slopes" labels in these areas. These labels should be removed. A note may be added
indicating that these areas are less than 25% based on new aerial topography to be confirmed by
field survey prior to final site plan. While the uses allowed by right or by special use permit in the
underlying district may be permitted if new topographic information (field survey) proves that the
slopes in questions are less than 25% [30.7.4.b.l.h], this does not change the preserved slope
designation. Note that if a field survey does not show that the areas in question are less and 25%,
all disturbance in those areas must be removed.
2. Alleys are required to intersect streets at two locations; however, dead-end alleys with turnarounds
may be permitted by waiver by the County Engineer [Design Standards Manual]. Please request
that the applicant submit a waiver request to the County Engineer for the proposed dead-end alley.
3. The grading on the proposed alley is unclear. There are no shown proposed contours between
512' and 522'. Proposed topography should be shown at 2' contour intervals. Note that alley
grades must not exceed 20% [Design Standards Manual].
4. Drainage easements for drainage passing through the site from offsite should extend to the
property line or ROW. See proposed 20' drainage easements located just off alley cul-de-sac and
at the private street entrance on to Sunset Ave. Ext.
5. Much of the proposed slopes in and around the SWM facilities are 2:1. Slopes greater than 3:1
require low -maintenance ground cover (not grass); this should be specified on plans.
6. There does not appear to be adequate vehicle access to the proposed SWM facilities. SWM
facilities must have a 10' wide access path graded at less than 20%. Grades exceeding 20% must
be graveled or paved [Design Standards Manual].
7. While it is important that proposed SWM facilities be shown on the site plan to review grading,
access, and treatment feasibility, etc., the actual SWM plan is not reviewed with the site plan but
with the VSMP. Therefore, the SWM plan sheet (5) should be removed from the site plan.
8. It is unclear whether the proposed sidewalks along Sunset Ave. Ext. are within the ROW. Please
request clarification. It is preferable that sidewalks be within street ROW.
9. Adequate sight distance on Sunset Ave. Ext. at the entrance to the proposed subdivision is not
demonstrated with this plan. Please request that the applicant include such an exhibit in the plan.
10. A safety fence should be provided for the retaining wall on lots 1 & 2.
11. VSMP and Road Plan approvals are prerequisites to Final Site Plan approval.
12. VDOT approval of the proposed entrance on to Sunset Ave. Ext. is required.
