ITEM: Public Hearing
Appl. #06-22P – Evergreen Walk Phase III
Mr. John Iennaco, a Project Manager with BL Companies came before the Commission to represent the Evergreen Walk, Phase III project. He explained that based on concerns voiced at the previous meeting, nine rain garden areas have been incorporated into the stormwater management design. Mr. Iennaco also informed the Commission that the existing sediment chamber that was installed for this site previously was found to be inadequate. An internal baffle will be installed with an elbow within the existing tank at the end of Tamarack. This retrofit will significantly increase the pollution removal efficiency of the unit. A new vortex treatment unit will also be installed that will serve the Phase III site. The infiltration system and rain gardens will treat 63% of impervious area on the site and the vortex unit
will treat 97% of the developed site. As a result of these modifications to the system, storm drainage calculations will be rerun and a new report will be submitted for the Town Engineer’s review.
Jeff Folger, Environmental Planner/Conservation Officer informed the Commission that with the structures on the site, this plan should far exceed the minimum required by DEP which is 80% removal of pollutants. The application and site plan presented should have a minimal, if any impact on the adjacent wetlands.
Answering questions from the Commission, Mr. Iennaco explained that the infiltration area has increased slightly because the original assumption of 2” per hour infiltration rate has been reduced to 1” per hour based on the soil exploration. The rain gardens have been constructed in order to allow low areas throughout the entire island with the exception of right off the top of the curb where you need minimal amount of slope. A three year monitoring system will be developed. The applicant will decide who will be doing the monitoring and the Town will receive reports.
Jeff recommended that an additional condition be placed on this application which would require retrofit of the sediment chamber west of Tamarack Drive to be installed prior to breaking ground. The installation will need to be approved by the Town Engineer. Jeff explained that the baffles that will be installed in this system will collect floatables, floating oils and sediment.

Control Measures.

11. Permittee shall establish a system to monitor and report on the effectiveness of the stormwater system. At a minimum, the monitoring shall determine the effectiveness of the rain gardens, the swale, and the detention basin. Parameters to be monitored shall include, but not be limited to, the effectiveness of infiltration, peak flow control, removal of suspended solids, removal of petroleum hydrocarbons, removal of metals, and the accumulation of transport of metals and hydrocarbons in the soil.
12. The monitoring program shall start approximately at the time the business opens. A soil baseline shall be taken at that time. A preliminary report shall be issued after one (1) year of monitoring and a final report after three (3) years of monitoring.
13. The program plan shall be reviewed and approved by the Town Wetlands staff prior to implementation.
Appl. #06-29P – Nation Interior Lot
Ms. Karen Isherwood, Project Engineer with Design Professionals came before the Commission to represent Mr. Doug Nation. She explained that this application is for a subdivision located at 250 Smith Street. The parcel is 3.8 acres in size. Over half of the site is swampy woodland and the remainder is an overgrown lawn/meadow mix. Approximately .76 acres of the site is wetlands. The site was flagged by Mr. Ed Pawlak and his report identified wetlands on the site. The application proposes two residential house lots. Lot #1 is traditional frontage lot and lot #2 is an interior lot. There will be a shared access driveway for both houses. The lots will be on public water, but will each have their own septic system. There will be no direct wetland impacts, but there will be 5200 square
feet of upland review area disturbance associated with grading. There is a potential for an additional 300 square feet of upland review disturbance for access and use of the two wells located to the rear of the property for irrigation purposes. This application offers the typical erosion and sedimentation control measures which are silt fencing down gradient of all disturbed areas and an anti-track pad located at the entrance during construction.
Answering questions from the Commission Ms. Isherwood explained that she believes that new wells are not allowed to be dug, but existing wells can be utilized. Ms. Isherwood said she would research this further to make sure this is a true statement. The two residential properties will be on septic systems. Mr. Robert Deptula, the Environmental Health Officer for the Town has approved the conceptual plan for these septic systems.
Jeff stated that the layout and the plan that is proposed will result in a minimal, if not negligible impact to the adjacent wetlands. Erosion controls are appropriate for the site.
Answering further questions from the Commission, Ms. Isherwood explained that the well closest to road will be abandoned.
Motion to: approve with conditions appl. #06-29P – Nation Interior Lot – 250 Smith Street – Inland Wetland/Conservation Commission application to create an interior lot, dwelling, yard and septic system on property northerly of Smith Street and easterly of Wheeler Drive. Rural Residential zone.
