Memorandum
To: Christopher Perez, Planning
From: Matt Wentland, Engineering
Date: 22 February 2016
Subject: Inglewood Terrace (SDP201600007)
The final site plan for Ingleside Terrace has been reviewed. The following concerns should be addressed;
1. Due to two conflicting stream studies, Staff requests that a third study be performed, either by a
third party agreed upon by both the homeowners and the developer or by the US Army Corps of
Engineers. This third study will determine whether or not a buffer will be placed on the parcels in
question and on all parcels downstream of the site.
2. Within the steep slopes overlay district, the maximum height of a single retaining wall is 6 feet
[18-30.7.5]. This plan proposes a 9' to 10' wall passing through an area designated as a managed
slope. Please adjust. Note that the minimum horizontal distance between individual walls in a
stepped wall system is 3 feet. Provide certified wall plans.
3. The width of drainage easements should be calculated using the formula found in the Design
Standards Manual (Easement Width = Pipe Diameter + 2' + 2(depth — 5') + 10').
4. The minimum width for a private road easement is 30'. [Design Standards Manual]
5. The minimum sight distance on a private road is 100' and the minimum K for a sag curve is 15.
[Design Standards Manual]
6. Verify that proper sight lines are provided at the parking on the inside of the curve on the private
road.
7. Show stationing on the road centerline on the plan view.
8. Provide a barrier or guard rail at the end of the private road.
9. VDOT normally requires a 45' radius for turnarounds on residential streets, but may not be
required due to distance from intersection.
10. The landscaping plan is showing trees planted inside the drainage easements directly over pipes.
11. Provide plans for the retaining wall and verification that there is no issue with the wall and wall
foundation being submerged during storm events. It appears the 100yr storm event overtops the
wall and runs into the buildings and the neighboring property.
12. Additional erosion control measures should be used below STI to ensure runoff does not enter the
neighboring property. Demonstrate how ST1 will function during construction. It appears that it
will be filled in almost immediately when the storm system and fill slope are installed.
Comments for Final Site Plan (previously provided by Michelle Roberge and remain unaddressed on
plans)
13. Retaining walls greater than 4' require railing.
14. A separate road plan will need to be approved and bonded prior to the approval of a subdivision
plat.
15. VDOT approval is necessary for connection to public road and for improvements within their
right-of-way.
16. Show groundcover, not grass, for slopes greater than 3:1.
17. A VSMP application shall be approved prior to the approval of the final site plan.
18. Verify guardrails are not warranted under GRIT manual. Otherwise, please show.
