Project Overview

The Mashpee Rotary is a five-leg, major regional transportation node with the intersections of Route 28, Route 151, Great Neck Road North, and Great Neck Road South. The Mashpee Rotary has been identified as a priority for investigation. The rotary is often congested, particularly in the summer months. Along the rotary and its approaches, congestion is a barrier to reliable inter- regional access between the towns of Falmouth and Mashpee to Barnstable and other towns on the eastern portions of Cape Cod. Residents and visitors navigating the rotary may be connecting to various destinations including Hyannis, North Falmouth, New Seabury, nearby retail and community destinations or the limited access highway, Route 6. There are prominent safety concerns in addition to the congestion issues. This study will serve as a continuation of the previous Route 28 study in Eastern Mashpee that included the Route 130/Route 28 intersection through the Orchard Road/Route 28 intersection.

Also of key concern is accommodation for all road users including motorists, pedestrians, bicyclists, and transit users. This is a heavily used corridor for non- motorized users looking to access their jobs and retail destinations from their neighborhoods.

The Mashpee Rotary is also identified as a high crash location according to the MassDOT ‘Top High Crash Intersection Locations’ portal. A review of the “Barnstable County High Crash Location” (Cape Cod Commission, 2014) lists the Mashpee Rotary as a top 50 crash location for several criteria:

  • Number of crashes – Rank #24 (28 crashes)
  • Equivalent Property Damage Only – Rank #25 (EPDO* 56)
*Equivalent Property Damage Only (EPDO) calculation multiplies 1 times the number of Property Damage Only crashes, 5 times Injury Crashes, and 10 times Fatal Crashes. To explore crash data for the Mashpee Rotary and other locations on Cape Cod view the Cape Cod Crash Dashboard.
 

Public Participation Goals

The goals of the public participation plan are as follows:
  • Gather input from community stakeholders and the public to establish a vision for the corridor
  • Solicit feedback of potential alternatives

Coordination Meetings

As key points in the project, coordination meeting will be held with CCC, Town, MassDOT, and CCRTA staff. Coordination with the Mashpee Wampanoag Tribe and other interested parties will also occur at key points in the project.
 

Public Meeting - Listening Session 

Public Meeting - Review of Concepts

The Commission staff presented conceptual design plans for review by the public at meeting on December 5. The presentation for those meetings, including the potential improvement concepts, can be found below.
Commission staff will incorporated feedback from the public into refined alternatives presented in the final report.

 

Final Report

Below are links to final report documenting the study and its recommendations. Thank you to everyone who participated in the development of this document.

The Cape Cod Commission is currently coordinating with the Town of Mashpee and MassDOT to initiate the next steps for a future rotary retrofit and shared use path project as part of the MassDOT Project Need Form process.

Mashpee Rotary Scope of Work - Public Participation
Mashpee Rotary Study Page 1 SCOPE OF WORK & PUBLIC PARTICIPATION PLAN Mashpee Rotary Study REDUCING CONGESTION, IMPROVING SAFETY, AND ACCOMMODATING ALL USERS BACKGROUND The Mashpee Rotary is a five-leg, major regional transportation node with the intersections of Route 28, Route 151, Great Neck Road North, and Great Neck Road South. The Mashpee Rotary has been identified as a priority for investigation. The rotary is often congested, particularly in the summer months.

There are prominent safety concerns in addition to the congestion issues. This study will serve as a continuation of the previous Route 28 study in Eastern Mashpee that included the Route 130/Route 28 intersection through the Orchard Road/Route 28 intersection. Also of key concern is accommodation for all road users including motorists, pedestrians, bicyclists, and transit users. This is a heavily used corridor for nonmotorized users looking to access their jobs and retail destinations from their neighborhoods. The Mashpee Rotary is also identified as a high crash location according to the MassDOT ‘Top High Crash Intersection Locations’ portal. A review of the “Barnstable County High Crash Location” (Cape Cod Commission, 2014) lists the Mashpee Rotary as a top 50 crash location for several criteria: • Number of crashes – Rank #24 (28 crashes) • Equivalent Property Damage Only – Rank #25 (EPDO* 56) Page 2 Mashpee Rotary Study *Equivalent Property Damage Only (EPDO) calculation multiplies 1 times the number of Property Damage Only crashes, 5 times Injury Crashes, and 10 times Fatal Crashes. Crash data is based off 2009-2011 MassDOT crash data. Any potential improvements along this corridor must be balanced with impacts on the environment and neighboring properties. DESCRIPTION OF SERVICES The Cape Cod Commission, under the Unified Planning Work Program, will conduct a transportation planning study for the study area with the following study goal: • Develop alternatives that will provide safe and convenient access within the study area for all users of the roadway system including pedestrians, bicyclists, and motorists. PROJECT LIMITS The study area consists of the Mashpee Rotary and the approaching roadways: Route 28, Route 151, Great Neck Road North, and Great Neck Road South. Please see the Study Area map below. Mashpee Rotary Study Page 3 PROCEDURES Task 1: Project Initiation Commission staff will gather past studies and develop a plan for analysis of the study area. This task will include meeting with Commission staff and a consultation meeting with Town of Mashpee and MassDOT District 5. Commission staff will also consult with Cape Cod Regional Transit Authority staff. Product: Final Scope of Work and Public Participation Plan Task 2: Data Collection, Mapping, and On-Site Reconnaissance Commission staff will gather data including crash locations, roadway geometry, traffic volumes, pedestrian/bicycle connections and land use information. At a minimum, traffic volume data will be collected at multiple locations along Route 28 and at Mashpee Rotary approaches. Commission staff will visit the study area to evaluate and photograph conditions. Town staff will be invited to attend the site visit. Task 3: Listening Session Commission staff will prepare for and host a public kickoff meeting in or near the study area where opportunities and constraints along the corridor will be identified. The meeting will include a brief presentation including information gathered as part of the first two tasks, but focus on input from the stakeholders in attendance at the meeting. Product: Summary of Listening Session Task 4: Concept Development and Refinement Information collected during the previous task will be reviewed with Town of Mashpee and Cape Cod RTA staff and preliminary concepts will be developed. Conceptual design plans will illustrate options for corridor improvements with a minimum of 3 alternatives. One of these alternatives will be the “no-build” scenario and will form the basis of comparison for any of the “build” alternatives. Product: Preliminary Concepts and Summary of Feedback Page 4 Mashpee Rotary Study Task 5: Public Review of Concepts After review of the preliminary concepts by Commission, MassDOT District 5, Town and CCRTA staff, the preliminary concepts will be presented at a public meeting. Feedback on the preliminary concepts will be used to refine those concepts. Product: Summary of Public Meeting Task 6: Draft and Final Report Concepts will be refined based on public comments and feedback from Town, MassDOT District 5, CCRTA, and Commission staff. Refined
