& Planning Board Members.
FROM: Anthony Oliveri, P.E.
SUBJECT: 900 King Street Redevelopment
Site Plan
Rye Brook, New York
DATE: March 6, 2021
With regard to the above mentioned project, this office has received and reviewed the
following:
1. Plan entitled: "Site Plan Approval Drawings, 900 King Street Redevelopment",
prepared by JMC, February 18, 2021;
2. Preliminary Stormwater Pollution Prevention Plan (pSWPPP) prepared by JMC,
dated February 18, 2021;
Our preliminary comments are as follows:
1.) It should be noted that our office reviewed Preliminary Site Plans during the EIS
process where much detail was covered; this review continues that process.
2.) The disposition with regard to ownership and maintenance of the proposed
sewer mains should be called out on the site plan.
3.) Both the proposed water and sewer mains will require approval from the
Westchester County Department of Health.
4.) Sufficient scouring velocities should be demonstrated for the proposed sewer
main with respect to expected flow rates.
5.) As detailed in the FEIS and previous responses regarding the water system,
certain planned upgrades to be performed by Suez were made a condition of this
development. SUEZ has previously provided a "willingness to serve" letter,
contingent on these upgrades and proposed water main extension associated

with the project to be completed within 9 months of the letter dated February 1,
2019. This letter must be updated by SUEZ and a schedule regarding completion
of the planned upgrades provided by the applicant.
6.) As detailed in the EIS the applicant has committed to Inflow and Infiltration (I&I)
removal of 80,000 gpd. A decision as to meeting this goal through a specific
project-based mitigation or through monetary contribution to the Village must be
decided.
7.) It should be noted that our office is currently conducting a more detailed review of
the provided Preliminary Stormwater Pollution and Prevention Plan and
associated calculations. The overall proposal does include a reduction to
impervious areas on this site which is consistent with previous pSWPPP
submittals.
8.) It is noted that 25 parking spaced have been included as “land banked”.
9.) The proposed fire truck access plan and onsite fire protection plans must be
reviewed by the Village Fire Department and Building Department for code
compliance and operational considerations.
10.) Construction phasing, sediment & erosion controls and associate staged
disturbance areas have been reduced and sequenced as a result of previous
comments during the EIS process. However, disturbance phases do still exceed
the maximum area as allowed by NYSDEC; this will require a NYSDEC waiver
for disturbance areas in excess of 5 acres at one time. As such, it is critical that
each phase and sub-phase be stabilized in strict conformance with the approved
site plan. Prior to initiation of each phase; the Village must verify that necessary
stabilization measures have been completed before authorizing the contractor to
proceed on to the next phase. This should be made a condition of approval so
that special attention is paid to these critical construction procedures. Failure to
do so may result in excessive runoff of silt during construction.
We will continue review of this application and any additional information that may be
received.
Thank You
