RE: Cascadia Blocks 1-3 Road and Storm Sewer As-Builts
I have made an inspection and performed as -built surveys of the roads and storm sewers in
Cascadia Blocks 1-3.
I certify that the roads and storm sewers have been built in reasonable accordance with the
approved construction plans. As -built public road plans dated July 20th, 2022 were prepared
based on field surveys of the final constructed improvement locations. The As -Built plans have
been submitted to the Virginia Department of Transportation and County of Albemarle. The as -
built plans show both the final horizontal and vertical alignments for the roads, the locations and
elevations of storm drainage pipes and structures, the locations of all stormwater easements, all
public road signage, sidewalks, and street trees. All horizontal and vertical variations between
the approved plans and the as -built features are indicated on the as -built plans.
The calculations on the following sheet have been provided for storm sewer sections that
deviated from the plans by more than construction tolerance. They have all been verified as
being in compliance with design standards:
