MOSHASSUCK RIVER PRESERVE ACCESSIBLE TRAIL DESIGN - RI
The Nature Conservancy in Rhode Island (TNC-RI) is seeking proposals for the planning and design of a long-lasting, evenly surfaced trail at its Moshassuck River Preserve in Lincoln, RI. The trail will be designed to allow persons with limited mobility, who might otherwise be precluded from hiking trails due to uneven surfaces and dramatic slopes, easier access to the preserve so they may participate in an immersive experience to enjoy the preserve’s natural features. The proposed trail will incorporate new pathways with portions of existing trail.
Scope of Project
• Site assessment, surveys & data gathering
• Conceptual design of accessible trail, bridge & amenities to meet FTAG/ABA guidelines
• Parking area plan to meet ADA requirements
• Refined concept of accessible trail, bridge & amenities after consultation with TNC-RI
• All permits necessary to construct project
• Final construction documents
• Assume five (5) project meetings (in-person and/or virtual)
Important Dates
• Scheduled onsite pre-bid meeting: Monday, March 20 at 10:00am (Site Location is the Moshassuck River Preserve, 3 Sherman Ave, Lincoln, RI 02865)
• Deadline for post-meeting inquiries by vendors: Thursday, March 23
• All inquiries answered by TNC-RI: Monday, March 27
• Deadline for proposals: Monday, April 10

Design Objectives
Objective 1: Accessible Trail & Bridge Design
The design product will be used to guide construction of a quality trail with a smooth durable surface that can be easily and safely maneuvered by persons with limited mobility and users with wheelchairs, strollers, walkers, and low speed devices. The accessible trail will, ideally, incorporate a variety of natural surroundings along its course to create an interesting and enjoyable experience for the user. The design will optimize trail surface stability and reduce erosion. It will include areas for wheelchair turnaround and passing zones at strategic locations. It will include amenities such as resting areas with benches, a wheelchair accessible observation platform near a waterway, and siting of a Clivus Multrum composting toilet at the trailhead parking area. Design plans will include a bridge spanning the Moshassuck River that crosses over culverts just downstream of an old stone dam. This section of trail periodically floods and will require a design that withstands, at minimum, a 10-year storm event. Please refer to Exhibit D. The trail may also include smaller stream crossings depending on the decided path chosen. The length of the trail will be determined by the final design but is anticipated to be approximately 0.5 miles. Refer to Exhibit C for a map showing two potential routes to be considered. The final design will meet or exceed guidelines for accessible trails and outdoor viewing areas consistent with the Federal Trail Accessibility Guidelines (FTAG) under the Architectural Barriers Act (ABA).
Objective 2: Parking Area Improvement for Adherence to ADA Requirements
The design plan will optimize the existing parking area to accommodate a wheelchair van drop-off zone and other designated spaces near the trailhead and will meet requirements of the Americans with Disabilities Act (ADA). The parking area currently has an unpaved dirt surface and is approximately 6,000 square feet. The drop off zone will ensure that the trailhead is readily accessible and approachable by individuals with limited mobility and those using mobility devices. Refer to Exhibit C parking area map for scale
Project Location
The Moshassuck River Preserve is a 210-acre nature preserve in Lincoln, RI owned and managed by The Nature Conservancy. It shares a boundary with the Fairlawn Golf Course and the MacColl YMCA property and is a relatively short drive from the City of Providence and other urban centers. It currently has 3 miles of hiking trails that meander through New England oak and hickory forest scattered with large glacial boulders. Refer to Exhibit A for trail map. Near the trailhead is an old stone dam and a small mill ruin where the trail crosses the Moshassuck River, which meanders through portions of the Preserve. Refer to Exhibit B.
