Subject: VCOD Site Plan Review
Applicant: Town of Yarmouth
Pumping Station 3 (PS3) at the Riverwalk Park, Boardwalk & Event Space
Dear Planning Board Members:
On behalf of the Town of Yarmouth (the Town), CDM Smith Inc. (CDM Smith) is pleased to submit a
Village Center Overlay District (VCOD) Site Plan Review Application for the Town’s proposed Pumping
Station 3 (PS3) to be located at the site of the Riverwalk Park, Boardwalk & Event Space. The design of
the PS3 site had originally been approved as part of the VCOD SPR 2023-1 decision issued for the
Riverwalk Park project.
The Town is seeking to modify the original design of PS3 to update the selected pumping technology
that will provide a more efficient and cost-effective facility for the Town. The original PS3 design was
based on a wet pit/dry pit-type pumping station which requires a larger building footprint to house
the pumps, electrical and related equipment. The dimensions of the footprint of the original pumping
station building, as approved in the Riverwalk Park decision, were approximately 40 feet x 50 feet.
Since the park decision was issued, the Town has refined the design of the collection system and
pumping station approach to utilize submersible pumps, which allows for a reduction of the building
footprint and results in an associated cost savings to the Town. As shown in the accompanying plans,
the dimensions of the pumping station building have been reduced to approximately 24 feet x 40 feet.
However, the architectural elements and materials of construction of the originally approved control
building remain the same in the modified design. The street-facing front of the building has only been
reduced by 10 feet, from 50 feet to 40 feet. Additionally, the grading and landscaping plan has also
remained substantially unchanged, with the same palette of native plant species. The stormwater
management system also remains the same since there has been a reduction in impervious area with
the modified design. The wet well, valve vault, and meter vault will be located mostly below grade,
but the top of the structures, as well as the first floor of the building and the electric transformer,
need to be at elevation 14 for flood protection. A designated location for future odor control
equipment, is also located on the site plan.
It is also important to note that this modification only relates to the pumping station portion of the
project. The remainder of the Riverwalk Park project remains unchanged.

Providing municipal wastewater service is part of the Town’s Comprehensive Wastewater
Management Plan to address nitrogen contamination in the Town’s estuaries; protect its drinking
water source; as well as promote redevelopment and economic growth throughout the Town. The
proposed pumping station is a critical component of the wastewater collection and conveyance
system and will provide needed service to the properties along Route 28. Flow will be pumped from
PS3 via a force main up to the proposed Water Resource Recovery Facility at 99 Buck Island Road.
We look forward to discussing these modifications further at the Board’s meeting on September 4,
2024.

additional information.
