- Vision: Transform the 50-acre post-industrial waterfront into a resilient, mixed-use, ecologically productive corridor that prioritizes public river access, affordable housing, local jobs, and biodiversity. - Remediation strategy: combine targeted soil excavation for hotspots, in-situ bioremediation, phytoremediation strips, and engineered caps to meet safety standards while minimizing cost and truck traffic. - Pilot phytoremediation zones using willows, poplars, and hyperaccumulators to treat heavy metals while creating green buffers and community education plots. - Brownfield reuse: retain structurally sound warehouse shells and convert them into mixed-use hubs to avoid embodied carbon from demolition. - Living shoreline: replace crumbling concrete docks with a graded, vegetated shoreline and modular oyster reef installations to stabilize banks, improve water quality, and increase habitat. - Flood-adaptive design: create tiered, floodable parklands that absorb storm surge, with elevated buildings on stilts or podiums and ground-floor floodproofed commercial spaces. - Soil management for housing: use clean imported engineered fill for building footprints, raised podiums, and planter-box containment where full remediation is infeasible. - Affordable, sustainable housing mix: modular mass-timber mid-rise buildings for rapid, low-carbon construction plus stacked micro-units, family-sized apartments, and artist live-work lofts. - Passive house and net-zero targets: require all new housing meet high-efficiency envelopes, heat-recovery ventilation, triple glazing, and on-site renewables to minimize operational emissions. - River-source heat pumps and district energy: install a river-source heat pump system and a low-temperature district heating/cooling network to serve housing and commercial blocks efficiently. - Modular floating housing cluster: pilot floating modular homes and co-housing on stabilized pontoons to increase waterfront housing without heavy land remediation and as a climate-resilience showcase. - Adaptive reuse hubs: convert warehouses into incubator spaces for makers, craft food producers, marine trades, cold-storage for local fisheries, and indoor markets that support small businesses. - Waterfront market promenade: year-round covered market space for producers, fishers, food trucks, and artisans integrated with cold-chain logistics and a licensed commercial pier for boat deliveries. - Aquaculture and urban fisheries: establish demonstration oyster farms and floating aquaponics greenhouses that improve water quality, provide local protein, and create tourism/education opportunities. - Public open-space network: continuous riverwalk with boardwalks, wetlands, pocket beaches, play areas, an amphitheater carved into a flood terrace, and fishing piers designed for equitable access. - Green corridors and biodiversity pockets: native plant meadows, pollinator corridors, and micro-forests that link to city greenways and improve urban cooling. - Recreational boating and water sports hub: mix low-impact boating (kayak/canoe launch), electric-boat ferry stops, and a community boathouse offering training and jobs. - Active transportation spine: protected bike lanes and pedestrian boulevards connecting the riverwalk to downtown, transit hubs, and neighborhoods, with car-free priority streets. - Electric microtransit and ferry service: add electric water taxis and coulomb-charged shuttle vans to reduce car dependence and link to regional transit and park-and-ride nodes. - Mobility hub: integrated station with bike-share, e-bike charging, cargo-bike logistics for last-mile deliveries, and real-time transit/river schedules. - Circular-economy infrastructure: on-site composting and anaerobic digestion for organic waste, community tool libraries, and a materials-reuse center recovered from demolition and renovation waste. - Renewable energy: solar canopies over parking and market roofs, façade-integrated PV, and a neighborhood microgrid with battery storage and smart load management. - Stormwater-first design: permeable paving, bioswales, rain gardens, and detention wetlands that double as public amenities and water-treatment features. - Cultural and industrial heritage trail: retain and interpret old machinery, rail lines, and dock features with signage, AR experiences, and artist commissions to celebrate local history. - Local workforce development: bind redevelopment to local-hire agreements, remediation training programs, apprenticeships in green construction, and incubator subsidies for resident entrepreneurs. - Community land trust and inclusionary zoning: set aside long-term affordable units, create rental protections, and support cooperative ownership models to address housing shortage and prevent displacement. - Business incentives: subsidized rents for creative startups, scaled permits for on-site food processing and cold storage, and pop-up retail zones to lower market entry barriers. - Programming and activation: seasonal festivals, night markets, waterfront cinema, school science programs tied to water-quality monitoring, and artist residencies that animate spaces while construction phases progress. - Governance and stewardship: create a waterfront conservancy with city, community, and developer representation to manage green infrastructure, programming, and ongoing remediation monitoring. - Performance metrics and transparency: deploy water and air quality sensors, biodiversity monitoring stations, and a public dashboard tracking social, economic, and ecological outcomes. - Phased implementation approach: start with hotspot cleanup, pilot floating park and warehouse activations, temporary tactical urbanism (pop-ups, markets) to build political and community support, then scale to housing and full infrastructure. - Funding strategy: combine green bonds, federal brownfield funds, public-private partnerships, community investment shares, and environmental impact financing tied to performance outcomes. - Risk-reduction measures: contingency for rising river levels, insurance strategies for waterfront infrastructure, and design flexibility to convert underused parcels into interim green space or renewable energy fields. - Equity and accessibility commitments: ensure ADA access throughout, multilingual outreach and signage, culturally relevant programming, and a participatory planning process with regular public workshops and living-lab pilots.
