EP conducted field investigations, borings, hydrologic-hydraulic modelling, and prepared bid and design documents for the Town. The designs incorporate new stormwater treatment for total suspended solids remove of as least 80% and subsurface infiltration below the roadways. The design will add up to 93,000-gallons and 17,000-gallons of stormwater storage and recharge on Thomas Street and Ring Road, respectively.

The project is expected enter the bidding phase this summer.

Over the past twenty years, the vacuum system has experienced system-wide failures from a variety of causes including storm-induced electrical malfunctions, extreme weather and storm runoff, and tidal inundation. EP evaluated transient electrical supply issues; compared system design standards to installed operating conditions; assessed operations and maintenance practices, troubleshooting, alarm monitoring, and emergency response; identified inflow contributions, and reviewed planned upgrades.

EP’s prioritized recommendations will increase the resiliency of the system under all operating conditions, while making the system more resilient to instantaneous disruptions from weather and tidal disruptions.

The site drainage was modified to prevent any flooding within the flood barrier wall during storm surge events. The existing catch basin discharge in the north corner of the paved area was fitted with a 12-inch gate valve. The manual gate valve will isolate the catch basin and prevent flooding from outside of the flood barrier wall backing into the WSPS yard through the basin. While the existing catch basin is isolated from the drainage outside of the WSPS, storm water will be collected into the existing catch basin via the existing on-site storm water collection system and will be pumped out of the basin with a trailer mounted dry-prime trash pump (supplied under this project).

The perimeter wall was designed as a reinforced concrete foundation and wall with New England stone veneer facing along the building. As part of the aesthetic design, the permanent flood barrier wall structure included a granite stone cap.

The new bridge will restore tidal flow into the river basin improving water quality, restoring native salt marsh habitat, increasing resilience of the floodplain, and reviving the river’s ability to sequester heat-trapping greenhouse gases.

This large environmental project is a true collaborative effort among the Town of Wellfleet, National Park Service, Cape Cod National Seashore, National Resources Conservation Service, National Oceanic and Atmospheric Administration, U.S. Fish and Wildlife Service, and Friends of Herring River as well as the contractor and consultant partners. EP will oversee construction with Weston & Sampson as the Owner’s Project Representatives. MIG Corporation has mobilized and is starting the initial phase of construction work.

October 2023 Update

The team is making steady progress on the Herring River Restoration Project!

The pile foundations are in place and the pier caps are being completed for the temporary bridge. A significant portion of the stone armor scour protection is in place. The temporary bridge superstructure work will be underway in October and November, allowing work to then commence on removing the old dike and the permanent bridge abutments. MIG Construction has completed over $5M of work to date on this $29M project.

February 2024 Update

Construction of the new, temporary bridge over Herring River has been completed by MIG Construction. The final step before the bridge can be open to traffic is the relocation of overhead utilities which will be commencing in the coming weeks.

The temporary bridge will now allow work to begin on construction of the foundations for the new bridge and tide gates. When this work is completed, the existing dike can be removed. The new bridge will restore tidal flow into the river basin improving water quality, restoring native salt marsh habitat, increasing resilience of the floodplain, and reviving the river’s ability to sequester heat-trapping greenhouse gases.

Over $9M of construction work has been completed to date from the $29.9M construction contract.

The City, in part with funding from the U.S. Economic Development Administration, is improving the resilience of the WPCF for future coastal storms and sea level rise. The City’s general contractor, Methuen Construction, has installed the earthen berm along the western side of the site. Concrete work for the flood wall along Essex Avenue is proceeding and the steel sheet-pile wall along eastern side of the site will be completed soon.

Construction is anticipated to be complete later this fall and include installation of four self-deploying flood gates for vehicle and personnel access points to the WPCF.
