RE: Response to Review Comments
Mt. Kineo Builders, LLC
47 Sharp Hill Road, Montville, CT
Dear Ms. Badalucca:
H+H Engineering Associates, LLC (H+H) is in receipt of the following review comments
regarding the Subdivision application (Application 25 Sub 7 & 25 SP 1) for the project located
at 47 Sharp Hill Road:
1. Preliminary Staff Technical Review comments received November 14, 2025.
2. Town Consulting Engineer comments dated November 17, 2025.
It is our understanding that the only item the Town has requested a response to is regarding
Engineering Comment #28. For convenience, the comment is restated below, followed by
our response in italics:
Town Consulting Engineer Review Comments:
5. The potential lot development along the west side of the road may intercept the
groundwater table. Provisions to mitigate groundwater breakout and footing drain
discharges should be considered. ADDRESSED
ADDITIONAL COMMENT: An additional DMH or clean-out to grade should be provided
at bend near the bioretention basins. The Town of Montville should not be responsible
for the operation or maintenance of the underdrain trench and piping beyond the right-
of-way limits. Easements and right of access and maintenance should be provided
across the subject properties.
RESPONSE TO ADDITIONAL COMMENT: An H-20 rated cleanout to finished grade (‘CO-1’)
has been added to the underdrain near the southeast end of Bioretention Basin ‘B’ and is
called out on the Drainage & Stormwater Management Plan (Sheet 7 of 18).
6. It appears a diversion berm/swale is proposed to the west of lots 13 and 14 through the
open space. More detail of this diversion should be provided including contributing
watershed, materials, and sizing. Who will own and maintain this diversion?

ADDITIONAL COMMENT: The plan call-out refers to a gravel swale, a riprap swale detail
is provided. Riprap is recommended; the final plans should be coordinated to indicate
riprap swale. The Town of Montville should not be responsible for the operation or
maintenance of the swale beyond the open space limits. Signage should be placed within
the open space along the swale indicating there should be no dumping or filling of the
swale.
RESPONSE TO ADDITIONAL COMMENT: The callouts on the Grading Plan (Sheet 6 of 18)
and the Drainage & Stormwater Management Plan (Sheet 7 of 18) have been revised to
indicate that the diversion swale will be constructed with riprap, not gravel, consistent with
the Riprap Swale Detail shown on the Stormwater Management Details sheet (Sheet 18 of
18).
11. Snow storage reserve area should be indicated at the turnaround per Section 70E.3 of
the Town Road Standards. ADDRESSED
ADDITIONAL COMMENT: The call-out on the final plans should be edited to indicate that
the snow storage areas shall remain free of obstructions including fences, landscaping,
and driveways.
RESPONSE TO ADDITIONAL COMMENT: The callout for the snow storage reserve areas
shown on the Subdivision Development Plan (Sheet 5 of 18) has been revised to indicate
that these areas shall remain free of obstructions, including fences, landscaping, and
driveways.
15. The water quality/bioretention basin area should be fenced off from public access. Gates
should be provided for Public Works access. ADDRESSED
ADDITIONAL COMMENT: A chain link fence construction detail should be included on the
final plans (see Road Standards Figure 24).
RESPONSE TO ADDITIONAL COMMENT: The Town of Montville’s chain link fence detail
has been added to the Site Details sheet (Sheet 15 of 18).
21. Street trees should be provided as part of the public improvements. PARTIALLY
ADDRESSED: Locations have been shown. Suitable native street tree species should be
proposed and a planting detail provided on the final plans.
RESPONSE TO ADDITIONAL COMMENT: The callout for the street trees shown on the
Subdivision Development Plan (Sheet 5 of 18) has been revised to indicate they will be
Littleleaf Linden (Talia Cordata) with a minimum height of 6 feet at the time of planting.
Our standard tree planting detail has been added to the Site Details sheet (Sheet 15 of 18).
28. The Town has historically had drainage issues around #19 Sharp Hill Road, including
runoff issues and icing in Sharp Hill Road. Impacts to the property and catch basin
located within #19 Sharp Hill Road and to Sharp Hill Road from the proposed
development should be evaluated.
ADDITIONAL COMMENT: The Applicants Engineer noted the installation of the new catch
basin in Sharp Hill Road will help to collect and convey stormwater to reduce the
potential for ponding/icing downgradient of the development. However, the previous
icing issues in Sharp Hill Road was primarily from overland flow from the properties
surrounding #19 Sharp Hill Road and potentially from the subject property (excerpt of the

Town GIS mapping attached). The Town previously installed storm drainage to capture
flow and mitigate the icing issues. Please provide commentary on the location and flow
from the stormwater discharge for this proposed development and potential impacts to
the downstream properties, existing
stormwater system and Sharp Hill Road. In particular changes in peak flow and runoff
volume for the combined Analysis Lines 1, 2, and 4.
RESPONSE TO ADDITIONAL COMMENT: This comment was previously addressed in
H+H’s letter dated November 17, 2025. In the Town’s Staff Report dated November 18,
2025, under the Agency’s Comments for the Staff Engineer, it is noted that this comment
was addressed to the satisfaction of the Town Engineer. No further comments or plan
revisions are necessary to address this comment.
Town Consulting Engineer Additional Review Comments:
1. The bioretention basin construction narrative requires inspection by the design engineer. CLA
recommends that the design engineer provide a letter certifying that the bioretention basins
have been constructed in accordance with the plans prior to acceptance by the Town.
RESPONSE TO ADDITIONAL COMMENT: Note #12 in the Bioretention Basin Construction
Sequence on the Stormwater Management Details sheet (Sheet 18 of 18) mentions that
the Design Engineer will certify the installed system. This note has been updated to
include inspection services and to clarify that a letter of compliance will be provided to
the Town certifying that the stormwater management system was constructed in
accordance with the approved plans.
2. The easement between Lots 14 and 15 should also include drainage easement language and
rights of access by the Town for operations and maintenance of the storm drainage
infrastructure and open space.
RESPONSE TO ADDITIONAL COMMENT: The drainage easement callout on the
Improvement Location & Topographic Survey “Record Subdivision” sheet (Sheet 2 of 18)
has been updated to mention rights of access by the Town for operations and
maintenance of the storm drainage infrastructure and open space. This will also be
reflected in the drainage easement language.
If you have any questions, please feel free to contact me at 860-980-8008 (office) or 413-
579-4488 (mobile).
