MINUTES —LEXINGTON CONSERVATION COMMMISSION June 12, 2007 Commissioners present: Joyce Miller (7:35), Dave Langseth, Duke Bitsko, Stew Kennedy Absent: Phil Hamilton, Angela Frick, Dick Wolk Others present: Karen Mullins, Administrator, Adam Bossi, Administrator Assistant, and Louise Vinci, Department Clerk Joyce Miller, Chair, opened the meeting at 7:35p.m. in room G -15, Town Office Building. 7:35 p.m. Meeting: RDA, 51 Le&�elawn Avenue, Present for the applicant /owners: Carl Dumas, Contractor, Kneeland Contracting, Sonia Demarta and Robert Bacon, applicant /property owners Carl Dumas presented a plan to remove a rear porch, replace porch with two -story addition (within 100 ft. of a stream), and add a front porch to a single- family residence. Comments from the Commission followed: David Langseth asked Mr. Dumas if he had looked at the feasibility of installing infiltration for roof runoff and what the net increase in impervious surface would be on the lot post construction. Mr. Dumas answered, that the total increase of impervious surface would be approximately 70 sf. He also said he had not considered adding infiltration because the lawn went right up to the stream bank and the runoff irrigates the lawn. Also, the owners plan to remove the paved driveway and replace with a pervious material. Mr. Langseth reviewed new revised Section 5(2) of the Code Rules and outlined that work involving adding less than 100 s.f of impervious surface over a three year period is exempt from complying with this section. Stew Kennedy noted that the stream is perennial, and hence defined as a river with a riverfront area extending 200 -feet horizontally and running parallel from the mean annual highwater line. Joyce Miller was concerned that work would be within 100 feet of the river, North Lexington Brook, and that the lawn extends to the bank of the river. She would like to see the lawn replaced with non - invasive plantings within the 25 foot critical edge to the wetland and bank. Lastly Ms. Miller stated the commission would need to review a critical edge enhancement plan. Motion made and seconded to issue a Negative Determination of Applicability with standard and special conditions as discussed regarding erosion control, pervious driveway details, and critical edge enhancement plantings, 4 -0 in favor. 7:50 p.m. Meeting: RDA, 19 Slocum Road, Present for applicant /owner: Christine McLaughlin, applicant /property owner.
