The future holds many unknowns and risks from a variety of climate-based hazards. But what will district life be like when the proverbial sun is out? A framework for flexibility, diversity and innovation is presently more achievable than planning for any specific metrics or standards of performance. By focusing on resiliency strategies that are multifaceted – that both delight and perform – we can ensure that stakeholders have an unmatched urban experience, even as they face the challenges of climate change. Global gateway cities will require resilient districts to remain competitive on the world stage and offer the lifestyle urban dwellers seek. The 100 Acre District must perform and captivate.

RESILIENT LINKAGES proposes a strategy that embraces the fluctuations of the tide and mounting sea level by building a higher level “ground plane” through both public and private investment in a responsive infrastructure and creating an aqueous Central Park that doubles as a water management system. Planning policies that raise the resiliency requirements and incentivize responsible building and contributions to the public realm ensure successful development of a desirable and resilient urban district.

• Apply targeted planning policies that provide incentives for responsible development and enable public/private investment in the District’s infrastructure and public realm.

• Create a vital urban district by including a comprehensive mix of uses and services in the development plan.

• Build a higher level “ground plane” through public and private investment in an elevated infrastructure.

• Install advanced sustainable systems for water management and treatment, energy production, distribution and building performance.

• Integrate a water park system to accept wicked high tides, storm surges and provide rainwater storage from roofs and streets in the form of cisterns for potable water and phytoremediated holding ponds.

• Connect the District to higher ground across the Channel to South Station and to the “Arks” at BCEC and Gillette.

RAISE THE ROAD

The development incentive framework is designed to hold public and private sectors to minimum baseline standard of development for resiliency shown in the strategies that must be deployed on all parcels. After those are conditions are met developers can obtain development incentives tailored to their site by deploying as many of the optional public benefits as possible. Incentives include height for parcels where height is desired. For other parcels, a range of non-dimensional incentives provides an opportunity for responsible development practices.

A water management and treatment system performs as an aqueous landscape of social space and recreation. Water is celebrated within the Central Park and enjoyed through water play areas, swimming pools, irrigated beds for urban agriculture, lush green open spaces, a beach, boardwalks, fishing docks and a terraced tidal play zone. The park is extended over the rail beds and surface road to the BCEC to serve as a conduit for water and renewable energy collection from its roof, and as a means of egress to the Ark in times of emergency.

At the base of the central inlet are two swimming pools floating in Fort Point Channel. Lights within these pools act as indicators of water cleanliness - red means danger and blue/ green means clear to swim.
