RE: 14 Enterprise Site Plan
CLA-5781N
Dear Marcia:
We have reviewed the site development plan and stormwater management memorandum
dated Oct. 24, 2017 submitted for the modifications of the facility at #14 Enterprise Lane. We
have the following comments:
1. Additional spot grades must be added throughout the site In order to define the
grading and drainage.
2. Access to the front door from the handicap parking space must be defined with spot
grading demonstrating conformance with standards.
3. Dimensions must be added to the plans to define location and size of modifications.
4. The slopes along the east and west perimeter of the rear equipment storage area are
steep. Railings must be added to the plans.
5. The grading appears to concentrate stormwater to the northerly corners of the rear
equipment storage area. The drainage must be defined and calculations provided to
back up the approach described in the stormwater letter and shown on the plans.
6. The location of the proposed trench drain at the bottom of the slope in the rear of site,
it likely will have a short term use. A ponded area may be more appropriate.
7. The "possible" drainage easement at the rear of the site would appear to have no
practical use, certainly not to the Town. It should be abandoned.
8. Referenced to CT DOT Form must be 817 in lieu of816.
9. The detail for the bituminous concrete pavement detail must show its proposed joint
with the existing pavement.
10. The proposed second driveway must be coordinated with and approved by the
Director of Public Work.
