Dear Mr. Mullen & Members of the Commission: 
 
On behalf of Kincora Waterford, LLC (Applicant and Owner), RJ O’Connell & Associates, Inc. 
(RJOC) is respectfully submitting this response to the comments received from the Town. 
Enclosed are twelve (12) copies of the full plan set dated 7/25/23. The revisions and sheets 
revised to address the comments include the following: 
 
Environmental Planner Comments – 6/30/2023: 
 
1) Comment: The existing CB at the south end of the parcel should not be used as part of the 
temporary sediment trap. This structure discharges to the existing subsurface detention 
system in the Aldi’s parking lot and should not receive construction stormwater run-off. 
Response: The Demolition and Erosion Control Plan (Sheet C-1A) has been revised 
to include a temporary swale which directs the construction stormwater run-off to a 
temporary sediment trap. The temporary sediment trap has been located adjacent 
to the existing catch basins as that is the lowest area on the parcel under 
construction. This design will allow all sediment to be trapped in the sediment basin 
before entering the catch basin. The temporary sediment trap will have an overflow 
rip rap spillway that is directed to the existing catch basin first, then to the new 
catch basin once installed and the existing catch basin is removed. Both catch basins 
will have inlet protection and filter bags installed.  Additional details for the 
temporary drainage swale and stone check dam have been added to Sheet C-5.  
Inspection and maintenance requirements for the temporary sediment trap have 
been added to Section 6.2 of the Erosion and Sediment Control Narrative on Sheet 
C-1C.  
 
2) Comment: ESC plan needs to indicate location, size, and volume of temporary sediment 
trap separate from the stormwater CB unit. 

Response: The temporary sediment trap is sized to hold a volume of 134 cy/ac (150 
cy total) and is based on contributing areas as depicted on the Demolition and 
Erosion Control Plan (Sheet C-1A) and noted in the Erosion and Sediment Control 
Narrative, Section 3: Construction Sequencing, Note F (Sheet C-1C).  
 
3) Comment: Include temporary sediment control protection in adjacent off-parcel catch 
basins. 
Response: Temporary sediment control protection has been added in adjacent off-
parcel catch basins as depicted on Sheet C-1A – Demo and Erosion Control Plan. 
 
4) Comment: Installation of the sub-surface detention chambers should be field-inspected 
during construction by design engineer to verify material type, depth and installation. 
Response: Subsurface Infiltration Field, note (3) has been revised to state the 
following: “Contractor shall notify engineer of schedule to install infiltration system 
to allow the design engineer to verify material type, depth, and installation of the 
field. As-Built Plan shall include all inverts for the subsurface detention system. 
Field inspection and As-Built verification of system shall be required.” (See Sheet C-
2 – Grading and Drainage Plan). 
 
5) Comment: As-built plan of the development to include all inverts for sub-surface 
detention system. 
Response: See response to Comment (4) above. 
 
6) Comment: Extend the temporary construction entrance to a minimum length of 50 ft. 
Response: The Temporary Construction Entrance has been extended to a length of 
50 feet as depicted on Sheet C-1A – Demo and Erosion Control Plan. 
 
Note: Inspection and cleaning requirements for all stormwater structures, including 
the isolator row in the ALDI parking lot subsurface infiltration system have been 
added to the Erosion and Sediment Control Narrative, Section 3, and Section 6.5 on 
Sheet C-1C. 
 
Fire Marshal Comments – 7/6/2023: 
 
1) Comment: I don’t have any comments for the project so far. I’m not a fan of the parking 
lot design and the fire apparatus needing to back in, but it appears there aren’t any other 
choices for the small foot print.  
Response: Sheet FT-1 (Fire Truck Turn Plan) shows the fire truck circulation 
around the parking lot without the need for the truck to reverse in. 
 
Utility Department Comments – 7/12/2023 
 
1) Please provide flow data estimates or provide actual flows from like facilities in business 
for at least 5 years. 
Response: Chipotle has a store close to this location and based on actual water 
meter readings the store will use approximately 1600 gallons per day (gpd).  The 
water information from the other store is as follows: 
  
Actual Use for a 4 month period was 25,400 Cu Ft (between 5/10-9/13) 
  
25,400/4 mos. = 6,350 cu ft per month 
6,350/30 days (avg) = 211.66 cu ft per day 
211.66 x 7.481 (conversion) = 1,583.33 gallons/day.  

 
Traffic/Police Department Comments – 7/12/2023 
 
1) After reviewing the updated plans and traffic impact study provided by the engineers, all 
previously discussed concerns have been adequately mitigated. I have no further 
comments for review. 
Response: Acknowledged. No response necessary. 
 
We anticipate these revised plans will adequately address your comments.
