Challenge
India Point Park is an 18 acre waterfront park located in the Northeast area of Providence at the confluence of the Seekonk and Providence Rivers. The park contains approximately three quarters of a mile of shoreline and serves as one of the City’s most heavily used public open spaces. Its landscape includes large lawn areas, mature tree plantings, formal pedestrian circulation paths, a playground, a central promenade with seating and gathering space, and extensive lighting and site furnishings. The shoreline is currently protected by a combination of vertical dry laid stone seawalls and angled riprap revetments. Due to its low elevation and direct exposure to riverine and coastal processes, the park experiences chronic tidal flooding, high wave energy, progressive erosion, seawall deterioration, and soil salinization, all of which are expected to intensify under projected sea level rise.
GZA is leading the India Point Park Resiliency Review and Feasibility Study and associated landscape architecture and civil and waterfront engineering design services for park improvements including coastal resiliency of the shoreline using green and hard infrastructure, improved public access to the shoreline including outdoor education, pedestrian walkways, earthwork and regrading, stormwater management and water quality improvements. Our client for this project is the City of Providence and The Nature Conservancy. The project is in progress and is currently on schedule and within budget.
Solution
The project began with a comprehensive assessment of existing ecological conditions, shoreline infrastructure, and coastal processes to establish a technical baseline for long term adaptation planning. Using detailed metocean analysis, GZA evaluated tidal hydrodynamics, wave climate, storm surge behavior, and water level projections under multiple NOAA sea level rise scenarios. This analysis quantified overtopping potential, runup, erosion susceptibility, and the performance thresholds of existing shoreline structures. Field investigations and structural and geotechnical evaluations were conducted along each shoreline segment to document conditions such as displaced riprap, undermined seawalls, low lying vegetated edges vulnerable to inundation, and stormwater outfalls lacking adequate scour protection or backflow prevention.
All shoreline infrastructure, both hardened and natural, underwent refined statistical and engineering analysis to identify areas where structural failure, erosion, or chronic flooding would compromise park operations, public access, or ecological function. These findings were integrated into a GIS based vulnerability assessment that mapped exposure under 2030, 2050, and 2100 sea level rise horizons. This analysis provided a clear understanding of how the park’s shoreline will perform under future climate conditions and where targeted interventions will be required.
Based on the modeling results and vulnerability thresholds, GZA’s coastal, civil, and waterfront engineers collaborated with GZA’s landscape architects to identify a suite of shoreline restoration and adaptation opportunities. These included natural and nature based features such as living shoreline treatments, fringe marsh creation, vegetated coastal buffers, and hybrid stabilization approaches that combine structural elements with ecological enhancements. Opportunities for seawall rehabilitation, revetment upgrades, upland grading, and resilient public access improvements were also identified. Key components of the concept design include:
- Living Shorelines: Introduced to stabilize the waterfront edge, reduce erosion, and enhance habitat connectivity. These soft-engineered systems support biodiversity while absorbing wave energy and tidal fluctuations.
- Floodable Coastal Vegetated Areas: Strategically placed to accommodate periodic inundation without sustaining major damage. These zones serve dual functions—supporting ecological processes and acting as buffers during storm events.
- Nature-Based Stormwater Infrastructure: Including bioswales, bioretention areas, and permeable surfaces that manage runoff, improve water quality, and reduce strain on conventional drainage systems.
- Expanded Tree Canopy: Enhancing shade, reducing urban heat island effects, and contributing to stormwater interception and air quality improvements.
- Improved Water Access: Providing safe, equitable, and ADA-compliant entry points to the waterfront for recreation, education, and stewardship.
- Repairs to Existing Shoreline Structures: Reinforcing aging bulkheads, piers, and revetments to extend their service life while integrating adaptive design elements that accommodate future conditions.
- Enhanced Circulation System: Reconfigured pedestrian and vehicular pathways to improve connectivity, accessibility, and emergency egress, while supporting multimodal transportation.
- Cultural and Memorial Gathering Spaces: Designed to honor local heritage and foster community cohesion, these spaces are elevated or flood-tolerant, ensuring usability during and after flood events.
GZA’s stakeholder engagement efforts for the India Point Park Resiliency Review and Feasibility Study centered on a coordinated, collaborative process that aligned technical coastal engineering analysis with the priorities of the City of Providence, The Nature Conservancy, regulatory agencies, and community users. Early scoping meetings with the City and TNC established project goals, resilience performance criteria, and evaluation metrics, while subsequent sessions focused on communicating metocean findings, flood vulnerability mapping, and shoreline condition assessments to build a shared understanding of risk. GZA facilitated iterative review cycles in which adaptation concepts; including structural, hybrid, and nature based shoreline strategies, were refined based on stakeholder feedback, feasibility considerations, and regulatory input from CRMC and RIDEM. Throughout the process, GZA incorporated community priorities related to public access, safety, ecological enhancement, and recreational continuity, ensuring that the resulting Conceptual Master Plan reflected both technical feasibility and stakeholder vision. This engagement produced a consensus driven set of shoreline restoration and adaptation recommendations and established a clear pathway for future design, permitting, and funding phases.
Benefit
This interdisciplinary process culminated in a Conceptual Master Plan prepared by GZA’s landscape architects, which integrates climate ready design with safe, accessible, and engaging waterfront recreation. The master plan was translated into an interactive ArcGIS Experience Builder web application (India Point Park Improvements (PVD Version) ) that presents the assessments and master plan concepts through maps, data layers, and dashboards, allowing users to explore and interact with the resiliency assessments, design concepts, and engagement program.
The assessment and conceptual design framework developed by GZA provides the City with a technically defensible roadmap for future shoreline improvements that enhance ecological function, increase biodiversity, support native fish habitat, and improve long term public access. These outcomes directly support Providence’s climate adaptation goals and position the City to pursue competitive state and federal resilience funding. To support implementation, GZA has provided grant writing and funding strategy assistance, preparing technical narratives, climate risk documentation, conceptual cost ranges, and justification materials for programs such as NOAA, NFWF, BRIC, and state coastal resilience grants. A benefit cost analysis (BCA) was not performed for this project. Additionally, the concept recommendations have been considered and developed to be aligned with Waterfront Edge Design Guidelines (WEDG) verification to enhance resiliency, ecology and access. By prioritizing the needs of communities and local ecologies, the proposed ideas will incorporate nature-based solutions to climate change while further enhancing public access and recreation to the park’s land and water resources.
Next Steps: Following completion of the feasibility and conceptual planning phase, GZA advanced the project into Phase 2 Contract Documents, including detailed engineering design, technical specifications, regulatory coordination, and preparation of bid ready construction drawings for selected shoreline segments. This phase includes refinement of hydrodynamic modeling, structural and geotechnical design of shoreline stabilization elements, integration of nature based features, and coordination with permitting agencies to ensure compliance with coastal zone management, wetlands, and floodplain regulations. GZA will continue to support the City and TNC through Construction Administration, including submittal review, contractor coordination, field observation, and verification that constructed elements meet design intent and long term performance objectives. This continuity from assessment through design and construction ensures that India Point Park’s shoreline improvements are technically robust, ecologically beneficial, and resilient to future coastal conditions while preserving and enhancing public access to one of Providence’s most valued waterfront destinations.
