| IRS990/Desc | 0 | The LNPA advocates at both the city and state level to advance the welfare of Linden Park residents as well as the broader surrounding neighborhoods. One recent example of this activity is the role that the LNPA played in working with city officials to plan the physical design of the nearby Grand Junction Multi-use Path and path access points. This feedback helps the city design a safe, accessible facility with attractive path entries from nearby neighborhoods, while addressing resident concerns about privacy and security. Another example is planning community block parties on our neighborhood streets, and inviting neighbors from the broader Wellington-Harrington neighborhood beyond the borders of Linden Park. Finally, the LNPA has successfully worked with the Massachusetts Department of Transportation to move a late-night locomotive holding point further south, away from the neighborhood and into a commercial area, greatly reducing the quality of life impact that idling locomotive noise had on surrounding neighborhoods. We regularly communicate with other neighborhood groups, especially the East Cambridge Planning Team, to find synergies in our civic activities and to work together whenever possible for the greater good of all eastern Cambridge residents. |
