RE: FDP202100003— Nystrom Driveway Crossing
Dear Frank,
We have received your comments dated 6/1/2021 and have provided the following
responses:
1. Clearly show area of cut/fill on the plan/profile views with a hatch.
RESPONSE: The cut/fill areas have been shown with a cut fill area on the plan and profile on
sheets 2 and 3.
2. Show stationing of driveway on plan views.
RESPONSE: Stationing has been shown for the driveway on the plan view sheet 2, 3 and 4.
3. Land disturbance does not qualify for an agreement in lieu of a plan. A VSMP application with
mitigation for stream buffer impacts is required.
RESPONSE: On 6/2/21 it was determined that this plan does not need a SWM (see attached
email). An agreement in lieu of a plan for SWM has been provided with this submittal. An agreement
in lieu of a plan for Erosion and Sediment control was provided with the initial submittal (Single family
lot with less than 1 acre of total disturbance) package. Mitigation for stream buffer application and
plan has been provided.
4. Confirm that plan view on Sheet 3 shows both abutments.
RESPONSE: All concrete sills have been shown with this submittal on sheet 10.
5. Provide permitting approval letter from the ACOE prior to VSMP approval.
RESPONSE: The permitting letter from ACOE has been provided with this submittal. Clear spans
do not require a Core Permit but do require a VMRC permit. See email from Vinny Pero to Jonathan
Nystrom dated December 10th 2020.
6. Driveways cannot exceed 16% slope. Revise slope shown on Sheet 2 to be below 16%. Advise to
adjust maximum slope to 15%to allow for construction error.
RESPONSE: Driveway slope has been adjusted so that it is shown at 15%.
