2023.10.12 Staff Report.pdf October 12 2023 Staff Report To: Conservation Commission From: Sarah LaValley RE: Staff Report, October 12 2023 Commission Meeting 5:30 PM Request for Determination of Applicability to determine if septic system installation in riverfront and bordering land subject to flooding (Mill River) is subject to the Wetlands Protection Act or Northampton Wetlands Ordinance. 182 MTR LLC, 182 Mt Tom Rd, Map ID 39-39 Application Overview: The property is without a functioning septic system, and is subject to a Health Department Order to design and install a Title V compliant system. The application proposes installation in a gravel area that is within riverfront area and BLSF, and potentially buffer zone. Consistency with the WPA and Northampton Wetlands Ordinance, Staff Recommendations: There are significant violations on the parcel that need to be addressed. While some work predated the WPA, degraded areas have expanded over time, including placement of the shipping containers shown on septic plans. Review of an RDA is an opportune time to correct violations on a site. However, a Notice of Intent application for other more expansive work is currently pending. Due to the complications of the site, the Commission could consider those violations comprehensively during the NOI review. The system will be installed in a gravel area that is currently used for vehicle storage and parking. If the Commission agrees that the work will not alter the resource area, issue a negative determination by checking box 2. 5:45 PM Notice of Intent for utility pole relocation and removal of 51 trees within riverfront area (Mill River) Massachusetts Electric Co, River Road right-of-way, Leeds. DEP File 246-772 Application Overview: The application proposes removal or relocation of seven utility poles from an off-road right of way to the roadway ROW within 10 feet of the paved footprint of River Road, and removal of 47 trees from the work area. Grubbing is not proposed; root balls to remain in place. DEP Comments: The Commission needs to wait to close the public hearing until NHESP has issued its determination. NHESP has issued a no-take determination: “the Division has determined that this project, as currently proposed, will not adversely affect the actual Resource Area Habitat of state- protected rare wetland wildlife species. Therefore, it is our opinion that this project meets the state-listed species performance standard for the issuance of an Order of Conditions.” October 12 2023 Staff Report 2 Consistency with the WPA and Northampton Wetlands Ordinance, Staff Recommendations: The work qualifies as a limited project, as detailed in section 5-1 of the application. Limited projects are certain categories of work that may be permitted notwithstanding performance standards, which this project would not meet absent this status. The Commission may still consider alteration and impose conditions. Evaluation of the riverfront area performance standards for redevelopment work is provided in section 5-2, but is limited to the pole work itself, and does not include an evaluation or assessment of the tree removal proposed as part of the project. It does not appear that the 310 CMR 10.58(5) standard that “At a minimum, proposed work shall result in an improvement over existing conditions of the capacity of the riverfront area to protect the interests identified in M.G.L. c. 131 § 40” has been met. Riverfront alteration also does not appear to be calculated correctly; the tree removal is not accounted for in the 52 sf of alteration provided as a total. The application asserts that the trees are ‘hazard trees’ but they have not been assessed by an arborist. Understory plantings, invasive species removal (there are significant invasives present in the work area), and replacement of trees is not proposed or discussed, but would all be appropriate given the number of trees proposed to be removed. 310 CMR 10.58 provides that “Riverfront areas are important wildlife habitat, providing food, shelter, breeding, migratory, and overwintering areas. Even some predominantly upland species use and may be seasonally dependent on riverfront areas. Riverfront areas promote biological diversity by providing habitats for an unusually wide variety of upland and wetland species, including bald eagles, osprey, and kingfishers. Large dead trees provide nesting sites for bird species that typically use the same nest from year to year.” The Commission should discuss how the project as a whole will protect these interests. While the relocation to the road ROW will eliminate the need for ongoing maintenance in the wooded area, the disturbed riverfront area should be carefully taken into account and additional conditions added that will ensure the work is an overall improvement. Leaving the area to revegetate naturally as proposed will take time, Some of the trees proposed for removal October 12 2023 Staff Report 3 may have limited success given ground conditions, and will likely include invasive species spread. If the Commission can make these findings, also add any construction- period measures necessary to protect the area; details regarding tree removal methods are not provided.
