Comments from the Commission as follows: Mr. Hamilton read the engineering report stating, “I have reviewed the calculations submitted for the plan changes at this site. The calculations done on the modified system show that, for the design storms, there is no increase in runoff rate and volume of flow after the project compared to pre-project conditions. We have no other comments.” Ms. Mullins raised concern that the original proposal was to mitigate 850 sq. ft. of roof area in the front. The plan is only for 450 sq. ft.

Comments from the Commission as follows: Mr. Hamilton read emails between Ms. Mullins and Mike Flamang, Town Engineer regarding the catch basins and drainage on Diamond Road. Ms. Mullins met with the project engineer who stated two additional pipes were in the area. Ms. Mullins suggested finding out where the two pipes originated. Mr. Waitt explained how elevations were determined and that no increased flooding would occur downstream to someone else’s property. Mr. Bitsko asked the guarantee of the isolated wetland functioning the same way it had in the past. Mr. Kirby commented on the successful plant life in the restoration areas and stated a two year monitoring schedule was included in the original Order of Conditions. Becky Linton of 22 Grove Street asked if chemicals were allowed to be used in such an area. Ms. Mullins read a condition from the original Order of Conditions; the use of chemical fertilizers, pesticides, herbicides and sodium- based products is prohibited within 100 feet of the wetlands to reduce the impact of these products on the resource areas when transported by stormwater or by leaching through the soil. This condition shall remain in perpetuity and shall not expire with the issuance of the Certificate of Compliance.
