The conceptual plan presented at the 2018 Weston Town meeting was prior to any data collection and preliminary analysis. While the current design is similar to the initial concept, changes in multi-modal accommodations were required. These changes in project scope can occur for numerous reasons:
- Information learned during data collection (such as traffic counts, or field survey)
- Reviews and input from stakeholders (such as the Town, MassDOT, and abutters)
- Changes to design regulations (such as MassDOT’s Engineering Directives).
It was through this conceptual design process that we learned more information regarding the existing conditions (average daily traffic and vehicular speed) of Route 30 in Weston. In addition, design guidelines were updated by the MassDOT after the 2018 Town Meeting.
Analysis of the existing conditions and the update to the MassDOT design guidelines required modification of the proposed cross-section. The process and reasoning for the design change were discussed at various public meetings by way of the Traffic and Sidewalk Committee.
