MEMO
TO: Chrstopher Bradbury, Village Administrator
FROM: Anthony Oliveri P.E.
DATE: May 17, 2024
SUBJECT: Draft DEIS Scoping Document Outline Review
975 Anderson Hill Road
Village of Rye Brook, New York
We have reviewed the following information for the referenced project:
DRAFT DEIS Scoping Document Outline 2024-03-27.
Full Environmental Assessment Form Part 1 – Project and Setting
Based on our review of these documents, we offer the following preliminary comments
with regard to the civil engineering, site, stormwater, sanitary sewer and water supply
infrastructure:
DRAFT DEIS Scoping Document
1. Page 6, 2. Project Description, §B.2: The presence of Floodplains (or lack thereof)
should be included in the Project Description.
2. Page 9, 5. Waters and Wetlands, §5.2: A discussion should also be included to
ascertain whether or not NYSDEC designated wetlands, watercourses and/or
buffers exist on or adjacent to the project property.
3. Page 9: A discussion regarding the presence of Floodplains should also be added.
4. Page 10, 6. Stormwater Management, §6.2: This discussion should not be limited to
just Village-owned properties that have an easement to discharge stormwater to
the Project site (emphasis added), but should include any Village-owned property
that may discharge stormwater to the Project site.
5. Page 11, 6. Stormwater Management, §6.3 first paragraph: This section should
include a discussion of the impacts of stormwater quantity control including
hydrologic modelling for pre and post construction conditions for the 1,10 and 100
year storm events. Also including capacity analysis of existing and proposed
infrastructure on-site and downstream as may be effected.

6. Page 11, 6. Stormwater Management, §6.3 should require the SWPPP to be in
conformance with NYSDEC SPDES GP-0-20-001.
7. Page 11: An additional section should be included which discusses Floodplain
Development, referencing Village of Rye Brook Code §130 Flood Damage
Prevention. This should minimize flood plain impacts and consider any downstream
impacts along the Blind Brook with a consideration to exceed minimum requirements
for stormwater peak flow rate and volume with regard to mitigating existing flood
impacts on the Blind Brook..
8. Page 18, 11. Infrastructure and Utilities, Water Supply §11.2.3: This section should
include a discussion regarding how the Project will affect the Veolia water system
supply model, regarding domestic and fire service water demand, flow volume and
pressure during peak usage times.
9. Page 18, 11. Infrastructure and Utilities, Water Supply §11.2.4: This section should
specifically include a discussion with a full description of any required upgrades to
the water supply system that are required to address the needs of the Project.
10. Page 18, 11. Infrastructure and Utilities, Sanitary Sewer §11.3.3 last (2) sentences:
This section should specifically state that sanitary sewer flow monitoring, CCTV
inspection and smoke testing will be required to be performed at such locations and
time periods as determined by the Village and the Village’s Engineering Consultant.
11. Page 22, 14. Construction, §14.2 Construction Phasing: This section should
specifically include a discussion regarding a description of the construction phasing
that will be required to respond to the NYSDEC limitations on open ground
disturbances that exceed 5 acres in area, along with discussions on related
stabilization protocols.
Full Environmental Assessment Form Part 1 – Project and Setting
1. Page 3 of 13, D. Project Details, §D1.e: This section should be indicated as “Yes”,
as the anticipated construction phasing of the project is acknowledged as still to be
determined.
2. Page 4 of 13, D. Project Details, §D.2.a: As the project contemplates an expansion
and/or re-configuration of the on-site water body, this section should address the
possible need for dredging and as such be indicated as “Yes”.
3. Page 5 of 13, D. Project Details, §D.2.b.iii: As §D.2.b.ii acknowledges that an
enlargement and/or re-configuration of the on-site water body is planned, this
section should address the likely disturbance of bottom sediments and be indicated
as “Yes”.

4. Page 6 of 13, D. Project Details, §D.2.e.iii, 2nd bullet: Stormwater runoff will flow to
adjacent downstream properties, and as such should be acknowledged by this
section as “Yes”.
5. Page 7 of 13, D. Project Details, §D.2.j.iii: Existing, proposed and difference in
parking space needs for the project should be included here.
6. Page 11 of 13, E. Site and Setting of Proposed Action, §E.2.h.iv, 3rd bullet: The
wetland name should be revised, and the approximate size of the wetlands listed
should be provided.
