inclusive, as amended, and the Waterford Inland Wetlands and Watercourses regulations.
This permit is a. grant of approval to conduct the following regulated activities:
e 
Clearing, excavation and grading associated with construction of a 24 unit residential
development served by a private driveway, municipal water and sewer, and a stormwater
treatment / detention system upgradient of inland wetlands and watercourses;
e 
Fill and grading within 7,000+/- square ft. of upland review area for the construction of a
portion of two stormwater treatment basin embankments and a graded outlet channel.
e 
Discharge of treated stormwater run-off to inland wetlands and watercourses.
These regulated activities ate associated with the proposed construction of a 24 unit residential
development located at 430 Mohegan Avenue Parkway & 23B Old Norwich Road, Waterford,
Connecticut. The proposed activities are depicted on site plans entitled; “Roberts Village Drive,
CGS 8-30g Affordable Housing, Site Development Plans For Conservation Commission
Review” prepared for 1721, LLC, 430 Mohegan Avenue Parkway & 23B Old Norwich Road,

approval to:minimize impacts associated with the proposed regulated activity and protect the
inland wetlands and watercourses on this site:
SPECIAL CONDITIONS:
1. Revised plan sheets 8 of 14 and 14 of 14, revision date 7/31/2024, shall be incorporated into
the final plan set for approval.
2. The authorized limit of permanent clearing and disturbance to the north and west of the on-
site wetland shall be identified as the wetland non-encroachment boundary. No activity,

including but not limited to clearing, grading, filling or removal of vegetation shall be
conducted within the non-encroachment area without specific authorization from the
Conservation Commission. The purpose of this vegetated non-encroachment area is to
protect inland wetland resources from direct and indirect impacts associated with adjacent
land development.
3. The wetland non-encroachment boundary shall be marked in the field prior to the start of site
clearing and approved by the Commission’s agent. Following construction, the non-
encroachment boundary shall be permanently marked at 50 ft. intervals with identification
markers provided by the Conservation Commission affixed to trees or 4x4 wooden posts.
4. At all times during site construction, temporary diversion swales and temporary sediment
traps shall be maintained to collect and settle site construction run-off and to prevent
sediment discharge to the receiving wetlands and watercourse resources.
5. Two groundwater monitoring standpipes shall be installed in the detention basins at the onset
of construction to.a minimum depth of two ft. below the completed depth of the basin. Depth
of surface ponding and seasonal high groundwater shall be monitored on a monthly basis for
the duration of site construction. A final wet basin planting plan shall be prepared by a
wetland scientist based on the collected basin hydrology data and submitted to the
Commission’s agent for approval prior to planting the stormwater basins.
6. The stormwater treatment basins shall be inspected by a CT licensed engineer during
construction to verify consistency with the approved plans and specifications. An as-built
survey of the stormwater system components shall be submitted to the Commission’s agent
with written verification from a CT licensed engineer that the system was constructed in
accordance with the approved design plans. This submittal shall be completed prior 
to
release of any bond amount.
7. Post construction monitoring of the stormwater basin vegetation and soil stabilization shall
be conducted by a wetland scientist or other qualified professional for a period of two (2)
years following completion of the stormwater basins to document vegetation.
establishment/success and functioning of the stormwater basins. Monitoring shall be
conducted 2 times per year during the early and latter part of the growing season and include,
vegetation establishment, depth of ponding and draw-down interval, slope and substrate
stabilization, basin plantings survival, and inspection of soil stabilization downgradient of the
basin outlets. Invasive plant species shall be removed from the basins. Total herbaceous
coverage of the basin areas shall equal or exceed 80% at the end of the second monitoring
year. Areas of erosion shall be repaired and re-planted under supervision of the

control measures.
3. At all times during site work and until soil areas are stabilized, the applicant shall install
and maintain erosion and sediment control measures such as fabric filter fence, staked hay
bales or other measures deemed necessary by the Commission’s agent to prevent erosion
and sedimentation impacts to wetlands and watercourses,

erosion and sediment control plan to reduce the potential for adverse sediment impacts.
C. Potential long-term impacts to on-site and off-site wetland resources are minimized by
Imaintenance of wetland hydrology, control of discharge velocities, implementation of
stormwater treatment systems, and maintenance of a vegetated. wetland buffer designated
as a wetland non-encroachment area.
