Ms. Mullins confirmed: all abutters within 1000 feet of the project limits will need to be notified by certified mail, the Hayden Woods Trust Fund will be covering the cost of mailings, legal ads, and application fees, the DEP will issue the filing number, and a separate application will need to be submitted to Natural Heritage because of the proximity to a vernal pool. Ms. Mullins asked the Commission if they had attended a site visit for 7 Fulton Road(ViewPoint Cloud 4 CTRE-20-8)regarding a potentially hazardous tree. Members of the Commission confirmed that they visited the site and, based on visual inspection, the tree did not appear to be a current hazard, except for a couple of minor dead limbs. The Commission is open to a certified arborist providing an evaluation of the tree for supplemental review. It was also requested that, if the tree is taken down, that it be replaced. 7:00 pm New Public Meetings/Hearings ViewPoint Cloud 4CNOI-20-21, DEP 201-1192 Notice of Intent, 3 Goffe Road Applicant: Lily Y Li Family Trust, Frank Hsieh and Lily Li, Trustees Project: Demolish in-ground pool and construct addition Documents Submitted.- -Plot ubmitted:-Plot Plan for 3 Goffe Road,prepared by Scott M.

Mr. Sperduto wanted to clarify that they are proposing a deck on the back of the house and no longer proposing the expanded peastone area. Mr. Sperduto also pointed out the benefits of the proposed landing, including a break in the fifteen steps for safety and that other configurations would require additional and more expensive piers. Applicants Evan Freeman and Michelle Yannetti raised concern about adding peastone on the downslope. Krisoula Varoudakis, designer for the applicant, also spoke to the Commission. Concerns of the Commission: -Cautions the applicant to be sure the dimensions have been carefully laid out and are not only schematic. -Does not want the stairway to end any closer to the wetland. Responses of the Applicant: -Fine with a condition for 3 feet of peastone at the bottom of the stairs. -There may be an additional tread. Measurements were taken off elevation of existing door. The rise and run were configured from that, but there was snow on the ground. -Can retain current distance from wetland edge by adding one of the treads to the top rise.
