A site walk was completed with the Applicant’s representative and Town Staff on June 9, 2023, to review existing site conditions. The project is located in the Light Industrial Zone and the proposed uses (office and warehousing/storage) are permitted uses in the zone per Montville Zoning Regulations (ZR) Section 12.2.2 and 12.2.5. The project includes activity within the upland review areas of delineated inland wetlands and is being reviewed by the Inland Wetlands Commission under application 23IWC7. There are FEMA regulated Special Flood Hazard Areas located on the property, however no activity is proposed within the 100-year flood plain and only minor surface restoration/grading is proposed in the fringe of the 500-year flood plain. The following documents were also received as part of the application package: · Hydraulic Modeling/Analysis Letter Report for 69 Fitch Hill Road Development prepared by Dewberry Engineers Inc. to Norwich Public Utilities indicating that there is adequate fire protection for each building individually. The letter recommends coordination with the Fire Department to determine if additional fire protection measures are required in the case that all three buildings were on fire at the same time. · Correspondence from the Montville WPCA indicating that an engineering study has been previously prepared for development of the subject property with regards to sanitary flows. Page 2 The following comments or question are based on review of the site plans dated May 25, 2023: · Please add phase limit lines to the plans if any of the proposed infrastructure supporting future Buildings 2 and 3 is intended to be constructed at a later date. · Please provide the Uncas Health District approval letter for the proposed subsurface disposal systems for the project file. o Please review the elevations of the proposed septic tank and leaching field for Building 1, there appears to be a typo. o Please review the elevations of the proposed septic tank for Building 2, there appears to be a typo. o Please review the elevations of the proposed leaching field for Building 3, there appears to be a typo. o Please review the proposed grading in the areas of the leaching fields for Building 2 and 3.

The line striping for the ADA aisle is missing from the lower parking space. · Please provide additional spot elevations on the west side of Building 3 to demonstrate that the ADA parking space does not exceed 2% slopes. · Please verify the parking space count and line striping around Buildings 2 and 3. It appears that some lines may be missing. · Are bollards or another form of protection warranted between the parking spaces and proposed Buildings 1, 2 and 3? · Please add details for restoration of the public right-of-way for the proposed utility connections and water main extension conforming to Town of Montville Road Standard and Improvement Details (RS) Sections 140B.3 and 140B.4. · Please provide a detail for the proposed driveway apron showing a 1-1/2-inch lip at the road edge per RS Section 130B.2. · Please confirm that the proposed driveway meets the minimum centerline radius of 75 feet per RS Section 130B.6. · Please demonstrate that the proposed driveway meets the sight distance requirements of RS Section 130B.8. · Is a stop sign/stop bar warranted at the exit to Fitch Hill Road? · Is a guiderail or similar barrier warranted on the driveway above the 10 to 15-foot slope descending into the site? · Is a designated loading space warranted/necessary for the 1,916 square feet of warehouse space remaining in the existing building? · Is a designated dumpster space/enclosure warranted for the existing building? · Please show the proposed utilities routes to service Buildings 1, 2 and 3.

Please provide details for the proposed sewer lateral and grinder pump if required. · Please provide details for protection of the proposed cleanouts from traffic within paved areas. · Is a construction level drawing for the proposed water main extension in the public right-of-way warranted? The drawing would demonstrate pavement restoration limits for excavations in the public right-of-way as well as how to maintain required separating distances from existing catch basins, drains, and other utilities in close proximity to the proposed water main.
