Bay Park Infrastructure Enhancements

After Superstorm Sandy, Hazen (in joint venture) prepared preliminary and final designs and provided start-up operational services to make the Bay Park facility more resilient. Upgrades included a flood barrier system for the entire facility and raised unit substations for added resiliency, as well as parkland improvements.

The Program consists of a comprehensive upgrade to critical elements of the facility. Materials were carefully selected during the design process. Wherever possible, "environmentally friendly" building materials were used. The electrical infrastructure building's design aesthetic was to create a lightweight structure that functions as thermal heat sink fins of a transformer. The fins extend from the interior of the structure to dissipate heat from the electrical equipment in order to reduce heat gain within the structures.

The Program has an overall budget of $830 million, with $450 million in construction substantially complete or underway. The joint venture team of Hazen and Sawyer and Arcadis (with subconsultant Cameron Engineering) provided master planning services for the upgrade, preliminary designs for all upgrade contracts, and final designs for the most critical aspects of the upgrade: the plant perimeter flood barrier and the electrical distribution system.

Designed by the JV, the berm and flood wall perimeter protection system is the plant’s primary line of defense. Substantially complete, the perimeter system will protect the facility from the projected 500-year storm surge and provides two points of access to the facility. A new electrical distribution system will replace the main and unit substations, with elevated facilities as an additional level of flood protection. Phase E1 is now substantially complete, consolidating four unit substations into three. For both fast track projects, design was completed within six months of notice to proceed and an aggressive construction schedule was established. The facility is flood hardened beyond any other Sandy-damaged facility in the Northeast United States within four years of the Superstorm.

As part of the recovery effort, the JV assisted Nassau County in applying for funding under the pilot FEMA 428 program. The program allows for up front funding of expedited critical repair and mitigation projects, crucial for the County with its limited bonding capacity. As part of the successful application, the JV prepared extensive damage and vulnerability assessments which categorized each asset into five prioritization tiers.

Getting Stronger Together

A vulnerability assessment of the facility was performed using the 500-year flood elevation and projected 50-year sea level rise, leading to the unprecedented combination of a full perimeter barrier system and elevated non-submersible equipment.

Project Outcomes and Benefits

  • Design includes the unprecedented combination of a full perimeter barrier system and elevated non-submersible equipment. New electrical unit substations, a critical element, were constructed above the projected flood elevation.
  • Intensive community outreach was conducted to keep the public informed of the efforts to improve their community through aesthetically-pleasing flood and energy resiliency measures.
  • Architectural design enhancements were incorporated to benefit the community, including an architectural finish on the concrete flood wall and access gates fronted by decorative and functional metal screen fins to improve aesthetics.
  • Park improvements included new synthetic athletic fields with subsurface drainage systems and green infrastructure elements. This eliminates standing water in the community areas under normal storm and tidal conditions, which had previously been an issue.
  • The building envelopes incorporated high recycled content and LED lighting systems for energy conservation and aesthetic appeal.
  • Project was named an ACEC NY Platinum Award winner.
