program in the Bipartisan Infrastructure Law (BIL), HNTB worked with the Massachusetts Department of Transportation (MassDOT) Environmental Section leadership to prepare a Resilience Improvement Plan (RIP). HNTB supported the development of MassDOT’s approach to resiliency as a combination of five resilience goals (PLAN, IMPROVE, MAINTAIN, RESPOND, INFORM), which build on state and federal regulations, past implementation efforts and actions, vulnerability assessments and interagency coordination. In addition to identifying priority resilience projects, MassDOT’s RIP identified action items that serve

7

With the Federal Highway Administration’s (FHWA) approval of this document and integration into the statewide long range transportation plan, MassDOT is set up for success in funding resilience investments with a 90 percent federal cost share for PROTECT program funded projects. This plan positions MassDOT to secure funding for both immediate and long-term resilience investments that support their systemic approach to surface transportation resilience. The RIP also serves as a clear roadmap for building resilience across the agency and communicating with other state and federal partners.

The area frequently faces severe flooding with recent events nearly overtopping the existing levee. After these incidents, levee owners and other stakeholders, in collaboration with the United States Army Corps of Engineers (USACE), decided to rebuild the levees to meet current USACE design and safety standards.

HNTB partnered with the USACE to provide planning and design services for flood risk management solutions.

The design minimized impact on rail companies, addressing complex operational, financial and scheduling concerns. Collaborative planning

The project improved 17 miles of levees, replaced two pumping stations, installed approximately 300 relief wells and relocated or modified more than 200 utilities along five mainline tracks. Twelve closure structures were built across tracks owned by the BNSF Railway, Union Pacific and the Kansas City Terminal.

This flood mitigation project boosted the reliability and resilience of the levee system by 200-percent, protecting $9.5 billion in infrastructure and safeguarding approximately 30,000 people who live and work in the area.
