Milton’s Conservation Commission scrutinized a proposal for two new single-family homes at 515 Blue Hills Parkway this week, raising significant doubts about the accuracy of the developer’s environmental filing. The project, which involves demolishing an existing structure to build two 2,100-square-foot homes near Pope’s Pond, faced immediate pushback regarding outdated wetland flags and questionable plant inventories. Chair John Kiernan opened the discussion by noting the application’s deficiencies, telling representative Garrett Tunison, I pride ourselves on being user-friendly, but I do note that your wetlands delineation is out of date. I'm wondering if you could update that for us.

Member Thomas Palmer, a botanist with four decades of experience in Milton, delivered a sharp critique of the materials submitted by Tunis Environmental Consultants. Palmer pointed out that the filing listed species like Salix daphnoides, which is typically found in Minnesota rather than Massachusetts. I've been botanizing in Milton for 40 years and never seen that here, Palmer said, adding that he also observed deep ruts at the site in December that suggest the wetland boundary may be closer to the proposed construction than current flags indicate. Tunison apologized for the errors, stating, I use an access database and sometimes I accidentally check a species I didn't mean to. Motion Made by J. Kiernan to continue the hearing to a site visit on May 2. Motion Passed by consensus.

The financial implications of tree removal also took center stage during the hearing. Chair Kiernan reminded the applicant of the town’s strict mitigation requirements, which prefer on-site replacement of mature trees with 2.5 to 3-inch caliper specimens. When on-site planting is not feasible, developers are required to contribute to a town fund. We have a virtual inventory where you can pay $700 per tree into a fund if they can't be planted on-site, Kiernan explained. Member Charles Bosworth emphasized a shift in town environmental standards, noting that the commission now requires compost filter tubes for erosion control rather than traditional straw wattles to prevent the spread of invasive seeds. We've been leaning toward compost filter tubes over the past several years, Bosworth said.

In a more collaborative exchange, the Glover PTO presented plans to restore the elementary school’s back field, which has become a muddy mess of compacted dirt. The proposal includes tilling the field to improve drainage into Turner’s Pond and planting five red maples to shade exposed play areas. Landscape architect Cody Klene noted, The play space is very exposed. We are proponents of trees as a long-term solution. Member Wendy Garpow shared a lighter moment, noting that a staffer for Senator Elizabeth Warren who attended Glover remembers walking ducks through the hallways, a tradition PTO Co-President Ellie Fischer confirmed has continued for 20 years. Motion Made by J. Kiernan to continue the Glover School field restoration hearing to a site visit. Motion Passed by consensus.

The meeting marked the end of an era for the commission as Kiernan announced the resignation of Ingrid Beattie after 19 years of service. Kiernan praised her deep expertise in biochemistry and her work on vegetation management plans. Beattie confirmed she will remain active in town government on a different board. In other business, the commission celebrated a successful restoration at Milton Woods on Blue Hills Lane. Dave Mashand reported that after several rounds of planting, the area is now fully established with native and volunteer species and are thriving. Palmer added his praise for the project’s drainage system, noting, Not one day did I see dirty runoff coming down that road. Motion Made by T. Palmer to issue a Certificate of Compliance for 175 Blue Hills Lane. Motion Passed 5-0 (J. Kiernan recused).

Finally, the commission addressed emerging infrastructure concerns, including a National Grid gas main replacement on Riverside Drive. Chair Kiernan expressed concern about flood risks in the area, stating he would require the utility to fill all trenches nightly. The board also briefly discussed the ongoing investigation into beaver dams near the town forest and unresolved questions regarding whether the methane collection system at the Milton landfill remains properly connected to regional infrastructure. Member Arthur Doyle noted that he and Palmer would continue to follow up with the DPW and Town Manager on the landfill's status.
