Dear Mr. Brown:
The Chazen Companies (Chazen) has received a submission package from your office for the above
referenced project. The applicant intends to construct a building containing a 27 senior housing units
with associated parking, recreational amenities, walking paths, lighting, and municipal utility
connections. Submitted information includes the following:
• Site Plans and Details titled "Legacy Land Holdings, LLC Fairfield Senior Housing" by Jarrett
Engineers, PLLC, dated September 13, 2016;
• SWPPP titled "Fairfield Professional Office Subdivision", by Jarrett Engineers, dated May 15,
2007 and amended on September 2016;
• Previous Site Plan titled "Stormwater / Grading Plan Commercial Subdivision Fairfield
Professional Offices" by Jarrett—Martin Engineers, dated July 2007;
• Town of Queensbury Site Plan Review Application;
• Project Narrative by Jarrett Engineers dated September 15, 2016;
• Impervious Area Calculations e-mail from Tom Jarrett to the Town, dated August 18, 2016;
• OPRHP Cover form, and;
• Requirements for Site Plan Approval dated September 14, 2016;
Your office has requested that we limit our review to the design of stormwater system as it relates to
compliance to local, state or relevant codes and regulations. Based upon our review, Chazen offers the
following comments for the Town's consideration:

Stormwater Management& Erosion and Sediment Control:
1. The project proposes to disturb an area of 2.6 acres that is part of a 17 lot professional office
subdivision referred to as Fairfield Professional Office Subdivision, which appears to be
permitted by a SWPPP prepared by Jarret Engineers on May 15, 2007 under GP-02-01. The
original 17 lot subdivision and stormwater system was previously approved by the Town and we
understand that the site still has General Permit (GP-02-01) coverage under an open Notice of
Intent (NOI). The Applicant has amended the previous SWPPP narrative in September of 2016.
The amended SWPPP does not propose any structural changes to the previously installed
stormwater system, as described in the third paragraph of Introduction section of the SWPPP:
"As of September 2016, two commercial projects occupy 3 of the originally approved 16
subdivision lots, and a proposed senior housing project will occupy 5 additional lots. The existing
and currently proposed development includes less impervious area than originally planned (and
designed) for the subdivision, therefore no modifications to the existing stormwater
management system serving the subdivision are necessary."
The Applicant has provided impervious area calculations, in an e-mail to the Town dated August
18, 2016, comparing the original subdivision and the proposed Fairfield Senior Housing. The
comparison shows a net decrease by 11,380 square feet. The Applicant states, "The net result of
the above exercise [comparison of impervious areas] shows that the original subdivision design
more than accommodates the current proposal."
Comments relating to the SWPPP amendment and documents provided are offered below.
2. The Applicant should clarify what areas were included for the "driveways/parking areas"
impervious area calculations presented in the email. Specifically, clarification as to whether or
not the impervious areas associated with the shared parking area located south of Baybridge
Drive were included; and if the future parking areas (associated with the proposed building)
were included in the impervious area calculations.
3. It is requested that the Applicant provide the subcatchment summary from the HydroCAD
model from the 2007 SWPPP, just for the proposed development area, to compare to the
currently proposed impervious area calculations.
4. The site plans do not include a grading or site plan for the shared parking area located south of
Baybridge Drive. Does the Applicant wish to construct the parking area under this site plan? If so
it is recommended that the Applicant provide site/grading plans for the area.
5. The Applicant has provided a copy of the NYS OPRHP Project Review Cover form completed by
the Applicant for the proposed project. The Applicant should provide the determination letter
and any additional documentation from OPRHP to the Town.
6. The proposed erosion and sediment control plans for the current proposal should be amended
into the original SWPPP as the proposed change constitutes a "modification" of the existing
SWPPP.
