The proposed activities are located within the outer portion of 'Previously Developed' Riverfront Area associated with an offsite, unnamed perennial stream. The Applicant proposes to implement erosion controls to minimize the potential for impacts to the resource areas during construction, and stormwater management to improve existing site conditions. Documentation Submitted: — "Drainage Plan" Sheet C-0; "Drainage Plan" Sheet C-1; Prepared by: Gala Simon Associates, Inc.; Stamped and signed by: Alberto M. Gala, PE Civil No. 36434; Date: 6/22/2021; Revised "Label, misc." 6/30/2021; — "Notice of Intent Applicant and Wetland Resource Area Analysis" and attachments; Prepared for Applicant/Property Owner: Amy Hung; Prepared by: LEC Environmental Consultants, Inc.; Date: 6/29/2021; — "Engineering Drainage Calculations for 12 Ledgelawn Avenue, Lexington, Massachusetts"; Prepared by: Gala Simon Associates, Inc.; Stamped and signed by: Alberto M. Gala, PE; Date: 6/22/2021; Ms. Julia Hoogeboom, LEC Environmental, and Mr. Al Gala, Project Engineer, presented before the Commission. Mr. Gala stated that soil tests pits were performed and groundwater was not observed. A DEP number has not yet been issued. Questions from the Commission: — Where is the construction entrance? — Why is the front half of the dwelling not included in the infiltration system? — Would like to see much more tree protection around the 34-inch maple on the southwestern portion of the front of the dwelling. It is very close to the access route and proposed regrading work, would prefer more root protection in place and something more semi-permanent like a chain link fence. Responses from the Representative: — The construction entrance is shown on the existing conditions plan, towards the end of the driveway. — The front half of the dwelling could be added into the drainage calculations, however, what is being proposed was sufficient to meet requirements. Could connect the downspout. — Would be open to a Condition that a certified arborist be on site to supervise the tree protection. On a motion by Mr. Beuttell and seconded by Ms. Dohan, the Commission voted 7-0 by roll call vote to continue the hearing to the August 2, 2021 meeting at the applicant's request. Record of vote as follows: Kevin Beuttell—Aye Duke Bitsko —Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye Phil Hamilton—Aye 7:33 PM (1:01:30 for LexMedia Recording) Abbreviated Notice of Resource Area Delineation: 475 Bedford Street ViewPoint Cloud Permit# CORD-21-1, DEP#201-#### Applicant/Property Owner: Cresset Lexington LLC Project: confirmation of resource areas Documentation Submitted: — "Existing Conditions Plan of Land"; Prepared for: Cresset Lexington LLC; Prepared by: VHB; Stamped and signed by: Russell J. Bousquet, PLS No. 35389; Date: 6/17/2021; — Photographs of site; Date: 4/20/2021; — "Abbreviated Notice of Resource Area Delineation" application and attachments; Prepared by: VHB; Prepared for: Cresset Lexington LLC; Date: June 2021; — DEP Bordering Vegetated Wetland (3 10 CMR 10.55) Delineation Field Data Form; 4 Sheets; Prepared by: VHB, Inc.; Date: 4/20/2021; Ms. Laura Laich, representative from VHB, presented before the Commission. The Site is the old Boston Sports Club location. Wetland extends nearly the entire perimeter of the site. In addition to BVW, there are a couple of isolated wet areas that have formed as a result of stormwater drainage that is running off the building and pooling in these areas. Ms. Laich and members of the Commission discussed enlarging the isolated wetland area, west of the existing building, on the site plan, as well as extending the Wetland 1 line closer to the parking lot edge on the east side of the lot(right side of site plan). The south/southeastern section of the property contains goldenrod. Ms. Laich mentioned waiting until the flowering plant blooms to be able to determine the specific species. This would be beneficial as some species are considered upland and others are considered wetland. Ms. Ladd stated that, after additional research, the species appears to be Canada goldenrod (Solidago canadensis), which is a facultative upland species. In the datasheets, wetland status is assigned to plants that are not identified to a species and the Commission won't accept that. Ms. Ladd raised concern that not all the species were captured entirely and Ms. Laich will reflag the area and update the plan. A DEP number has not been issued yet. On a motion by Ms. Ladd and seconded by Ms. Dohan, the Commission voted 7-0 by roll call vote to continue the hearing to the August 2, 2021 meeting at the applicant's request.

Details were added to the site plan regarding shrub plantings on the rear depression at the request of the Commission during the previous meeting. It was asked why no shrubs are being proposed near the front depression and side yard slope and Mr. Clarke responded that he believes they are non-existent for aesthetic reasons. A concern of the Commission is that lawn chemicals could be used and would not be filtered prior to entering the depression. A Condition will be added to include native ground cover or shrubs to protect the depression in the front yard and sloped area in the southeastern side yard. On a motion by Ms. Samuels and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to close the hearing.

Mr. Tim Power, Project Engineer with PVI Site Design, stated that there will be an overall reduction in stormwater flow for all storm events, however because of the configuration of what was previously built, the proposal is not able to meet the volume requirement. Comments from the Commission: — Can you round out the lawn restoration area behind the shed towards the rear yard? Plants rarely grow in straight lines. — Have you explored the possibility of more infiltration units, perhaps on the lower left side of the site plan (front yard)? Shallow depth to groundwater in the rear yard. — If the house is considered existing then it is not complying with our performance standards. Would feel more comfortable having a comparison in the record. Mr. Kirby stated that, due to the recent heavy rainfall, the soil has been disturbed to the east of the driveway and requested permission to install the proposed landscape to help eliminate more soil disturbance and erosion onto the driveway. 14 Village Circle: update on enforcement order, violation of patio work without Conservation approval Mr. Mark Arnold, Goddard Consulting, presented before the Commission on behalf of the property owner. Mr. Arnold presented the restoration and planting plan that includes Feno boundaries.
