CONDENSED COMMENT RESPONSE SUMMARY 
FROM: 
Planning & Zoning Commission 
RE: 
61 & 61A Myrock Avenue Site Plan Review 
RESPONSE DATE: May 3, 2023 
DEPARTMENT: PLANNER – 4/25/23 
Application as presented is for the construction of a multifamily project with six residential 
buildings containing 36 units in each building. A total of 216 units. Five freestanding garages, a 
maintenance building and recreational amenities are also included in the project. A commercial 
building currently exists on the parcel and will remain and continue to be used as a commercial 
use. 
1. The narrative and statement of use does not refer to the existing commercial building. What is 
the intended use of this building. The site plan narrative must also include the proposed use of 
the existing commercial building. 
Response. The narrative and statement of use has been revised to include a description of the 
existing commercial building and proposed use as office space, which is a permitted 
use under Section 8.1.3. The office space use is described in the Zoning and Parking 
Tables on Sheet 2 of the plan set. Use and square footage labels have been added 
to the existing building. 
2. The site plan set does not contain a boundary plan and topographic survey. All boundary and 
survey information must meet the accuracy to A-2 standards. 
Response. The surveys maps prepared by Franklin Surveys for 61 and 61A Myrock Avenue 
have been added to the plan set. Also included in the revised plan set is a Lot Line 
Revision Plan. 
3. Consider providing additional pedestrian connectivity between the previously approved 
multifamily project to the west and this proposed project. Especially to the recreational 
amenities. 
Response. A sidewalk has been added along the north shoulder of the central driveway 
connecting the sidewalks for Buildings E through J with the terraced recreation 
areas, pickleball court, and Waterford Woods sidewalk network. 
4. Provide measures that increase pedestrian / vehicle awareness at location of proposed sidewalk 
at main access drive, i.e. crosswalk, signage. 
Response. A crosswalk and additional ramp of the west side of Waterford Woods main 
entrance driveway has been added. 
5. Show locations of directional signage on the site plan. Directional signs are listed in the site 
layout legend but do not appear on the plans. 
Response. Directional Signage shown on the plans and labeled as requested. 
6. Provide details of all proposed light standards. Note that all lights must be directed downward 
and dark skies compliant.

CONDENSED COMMENT RESPONSE 2 
Response.  A Light Pole & Base detail has been added to Sheet 12. 
7. The Traffic Impact and Access Study will be submitted for a review by a Third Party selected 
by the Town. The previously approved Zone District amendment to C-MF discussion identified 
that when the site plan is submitted for the multi family project that the Commission would 
want the Traffic Study reviewed by a third party. The Town has provided the On-Call firm 
with a copy of the plans, Traffic Study and all other documentation submitted in order to the 
on-call agent to determine a scope of work and a cost. This cost will be borne by the applicant. 
Response. Noted 
8. Provide details regarding Under-story Enhancement along buffer with residential zone district. 
Response. The side yard screening enhancement and understory enhancement areas consist of 
staggered rows of arborvitae Green Giant and American Holly evergreen plantings. 
The plant types and approximate locations are shown on the landscape plan. 
9. All internal driveways are to remain private. Do not assign street names to internal drives, i.e. 
Grand Oak Boulevard, Upper Trail. This will lead to confusion. 
Response. Private road names have been removed from the plan. 
10. Use of internal driveway at existing commercial building as a construction entrance indicates 
that construction vehicles will be utilizing Myrock Avenue. All construction vehicles should 
access the site from existing Willetts Avenue driveway entrance. This will alleviate potential 
traffic conflicts with construction vehicles and residential and pedestrian traffic on Myrock 
Avenue. 
Response. The intent of connection to the northwest corner of the commercial building 
parking area is to allow construction vehicles to access the portions of the building 
used for storage and office related to the new multi-family development. A 
construction fence will be installed at the southwest corner of the commercial 
building to prohibit regular construction access to Myrock Avenue. Additional 
notes and a construction fence have been added to the plan for clarity. 
11. Are there adequate site lines / stopping distances for local traffic and construction vehicles at 
the proposed temporary construction entrance on Willetts avenue east of the existing drive? 
Suggest utilizing the existing established drive on Willetts Avenue in order to reduce traffic 
conflicts with local traffic. 
Response. The temporary construction entrance has been relocated to the westerly property 
limits to maximize sightline to the east. 
12. Consider relocating easternmost dumpster further from residential properties. 
Response. The dumpster pad has been relocated to the central parking area adjacent to the 
stormwater treatment meadow and pond. 
DEPARTMENT: FIRE MARSHAL – 3/30/23 
1. The only issue found is an additional hydrant will need to be added south of either building L 
or K.

Response. An additional hydrant has been added at the southwest corner of Building K as 
requested. 
DEPARTMENT: PUBLIC WORKS – 3/31/23 
1. No Garbage or Recycling collection will be picked up by the Town. 
Response. Comment noted. Trash and recycling will be contracted with a private company. 
DEPARTMENT: ENVIRONMENTAL PLANNER – 4/26/23 
1. Include isolated wetland pocket on site plans. 
Response. The isolated wetland pocket has been added to the plan set. 
2. Revise limits of temporary and permanent disturbance to provide a 100 ft. non-disturbed area 
upslope of the isolated wetland. Areas of low- or no-mow vegetation plantings should be 
removed from the 100 ft. URA. 
Response. The downgrade limit of work has been added to the plan set and a note added stating 
that the existing grass & shrub vegetation to remain. 
3. Is a landscaping plan sheet missing that shows proposed activity in area south of maintenance 
building at south end of project area - 
Response. Sheet 15 has been added to the plan set showing the landscaping activity at the 
south end of the construction site. 
4. Vegetated swales may require stone check dams both during construction phasing and post-
construction to control sediment erosion and transport. In particular the longer swales south of 
Bldg H, west of Bldg L and east of extended detention pond. E&S narrative / specification for 
swales should include frequency of maintenance and removal of accumulated sediments. 
Response. Stone check dams have been added to the plan and labeled. Inspection note 4.B.v 
has been added related to maintenance. 
5. Consider discharging garage roof run-off to adjacent vegetated islands or maintained areas 
where practicable. 
Response. The garages do not have gutters. The rear pitch of the single bay garages discharge 
to vegetated swales. The front pitches will enter the storm collection system. 
6. During phased construction, where is stormwater run-off being directed to during each 
proposed phase? Will TST’s serve as stormwater controls until filter basin and wet pond 
constructed? Concern with mixing post-construction run-off volumes from Phase 1 with 
construction run-off from phase 2 and 3 and the potential for failure of temporary basins. 
Response. Each silt trap is labeled by Phase with area and depth. The sequencing has been 
coordinated with the silt trap locations. Silt traps 1, 2 and 3 will accommodate the 
bulk of the site work and construction of 4 out of the 6 new buildings. The 
foundations for the last two buildings will also be installed. Once Buildings G, H, 
I, and J are completed, with the surrounding landscaping and vegetation installed, 
Silt Trap #3 will be removed and the treatment bed installed. The site work 
remaining after installation of the treatment bed will be the areas around Building

CONDENSED COMMENT RESPONSE 4 
K and L. Silt Trap #4 has been located to receive all of the construction stormwater 
from these unstabilized areas to minimize the potential for compromising the 
treatment bed soils. In addition, the long flat swale from Trap #4 to the treatment 
beds will provide greater opportunity to control sedimentation within the check 
dams. 
7. Permanent stormwater forebay and filter basin should include ESC measures to reduce 
sediment deposition in these components during phased construction period. 
Response. ESC measures have been added, including stone check dams down grade of the 
discharge points (flared end and swale), and ECB slope protection on the easterly 
slope of adjacent to the treatment bay. 
8. In ESC narrative, include anticipated time frame for completion of each of the construction 
phases. 
Response. Approximate completion dates are provided in ESC Note 1. Estimated duration of 
each phase has been added to the Sequence of Construction. 
9. Clarify extent of site disturbance for each phase, specifically the rough grading and utility 
installation work. 
Response. The total area of disturbance for the project is approximately 14.9 acres as stated in 
the ESC Control Narrative. The area of each phase has been added to the narrative. 
In order to tier and balance the site, the mass earth work will be completed through 
Phase 1 and 2. 
10. Additional sediment / run-off control measures and anti-tracking measures should be 
considered to prevent construction run-off and tracked materials from entering the completed 
driveways and stormwater collection system at the adjacent Waterford Woods. 
Response. Additional control measures will be considered. A skid steer mounted sweeper has 
been allocated to the site for sweeping roads and driveways. 
11. Construction notes should include this project requires a CTDEEP Construction Stormwater 
Discharge permit. 
Response. Added as General Construction Note 3 on Sheet 12. 
Stormwater Treatment 
12. Cross section details are requested for the stormwater treatment basins illustrating the elevation 
and volume provided for a) water quality volume, b) permanent wet pool, and c) flood storage 
elevation. [If the extended detention pond has an 8 inch outlet at the bottom of the basin, how 
does this basin contribute in capturing and treatment of water quality volume?} What is the 
anticipated hydraulic residence time? 
Response. The treatment area, including the sediment forebay and filter bed / gravel wetland 
will fully retain and treat the WQV prior to discharge to the attenuation pond. The 
storage volume below the riprap weir crest elevation 38.00 is 0.46 acre-ft, which 
exceeds the calculated WQV for the entire site. It should be noted that the retention 
and treatment volumes of the rain gardens and vegetated swales throughout the site

are not included as a conservative measure and will further enhance the treatment 
capabilities of the entire stormwater system. A Treatment and Detention Section 
has been added to Sheet 17. 
13. To provide improved water quality treatment function, provide a vegetated aquatic bench or 
shelf in the wet detention pond and provide a planting schedule for wetland “plug” plantings. 
Response. A shelf has been added to the north and east embankments of the detention pond as 
shown on the grading and landscaping plans, extending 1’ above the typical pool 
elevation and 2’ below. Plug planting species and quantity will be provided to the 
Town for review prior to filing. 
14. Is an emergency spillway needed to direct flood flows away from the adjacent stormwater pond 
on Waterford Woods property? 
Response. An emergency spillway is provided on the south embankment of the Pond to direct 
overflow to the south and away from the adjacent Waterford Woods site. The 
detention basin has been designed with a minimum freeboard of 1’ for the 100-year 
storm event. 
15. Deep test pits are not available for the filter bed basin. Is seasonal or permanent soil saturation 
anticipated in the filter substrate? Is there a possibility to convert the filter layer into a 
subsurface gravel wetland cell (per UNH Stormwater Center) by substituting gravel for the 
filter media and adjusting the perforated underdrain inverts to keep the bed saturated 4-8 inches 
below the soil media layer. This will increase nitrogen attenuation of the treatment system. 
Response. Soil tests were performed within the treatment area with results transmitted under 
separate cover. It appears that the existing subsoils are low permeability and 
seasonally high groundwater was observed 4’-6’ below grade. Given these 
conditions, we agree that a gravel wetland will enhance the treatment capabilities. 
The plan grading and stormwater design has been updated to incorporate the 
saturated gravel wetland feature with appropriate distribution and subdrains. 
16. Whether sandy or gravel filter media layer, include clean-out / inspection ports to underdrain. 
Consider installation of perforated risers above the floor of the basin to promote surface water 
into subsurface filter layer. 
Response. A perforated riser has been added to the north end of the gravel wetland to promote 
surface water into the gravel layer. A solid riser is provided in the southerly 
subdrain at the point of discharge for further inspection. 
17. Note: UNH Stormwater Center recommends eliminating compost component from 
bioretention filter media. 
Response. The filter media will be 50% topsoil and 50% sand. The mulch has been eliminated. 
DEPARTMENT: UTILITY – 4/27/23 
1. Please use WUC details for all sewer and water details.

2. Please identify / callout fire and domestic services individually. Per Water Note 4 on Sheet 10 
sizes of services are TBD, but will be sized and called out on plans at time of building permit 
application. 
Response. The individual fire and domestic water supply lines are called out for each building. 
The utility plan will be finalized for construction upon completion of the MEP 
designs and submitted as part of the building permit review. 
3. Please terminate the water main between buildings K & L with a hydrant and move the fire 
and domestic service connections upstream of the hydrant for water quality purposes instead 
of 8” cap and blowoff. 
Response. The water main has been extended to the south to accommodate a new hydrant at 
the southwest corner of Building K as requested by the Fire Marshal. The supply 
lines for Buildings K and L occur before the terminating hydrant. 
4. SMH near the NW corner of Garage G800 proposed TF is lower that FL elevations, please 
revise. 
Response. The top of frame elevation has been corrected. 
5. SMH south of pickleball courts shows a stub or some kind heading east with no label, please 
clarify. 
Response. The stub has been removed from the plans. 
6. Add chlorination taps at loop tie in points to the existing main on Grand Oak Boulevard so that 
the new main can be charged, tested, and treated as needed since the existing main is serving 
occupied buildings. 
Response. Chlorination inlets have been shown and labeled at the proposed tap locations.
