At the April 28 Planning Board meeting, residents voiced serious concerns regarding the rapid increase in housing density and its impact on Lexington's infrastructure and character.
During discussions on the 331 Concord Ave and 16 Clark Street developments, community members raised questions about construction nuisances—specifically rock blasting and heavy truck routing on narrow streets. Rather than requiring the applicants to present a formal noise or traffic mitigation plan during the hearing, the Board directed residents to wait for responses through the applicant's online portal.
Furthermore, when a resident requested a traffic study to assess the impact of high-density projects near the library, the Board Chair stated that the Planning Board lacks the legal authority to mandate such a study. This leaves residents with a difficult question: if the Board cannot mandate studies for traffic or noise, how can we ensure these major developments won't overwhelm our streets and neighborhoods?
As these 'by-right' developments move forward, it is vital that we continue to demand specific, evidence-based answers regarding our town's ability to support this growth.
Public impact
Significant increase in housing density and changes to the visual skyline/streetscape.
