Ms. Rachel Juba Page 2 c. If the existing wetland is to be used for stormwater treatment, pretreatment must be provided prior to discharge into the wetland. d. Based on the wetland characteristics described in the NOA, the wetland is classified as "Slightly Susceptible". Bounce requirements and inundation period requirements are as follows: i. Permitted storm bounce for 2 -year and 10 -year event is existing plus 1 foot. ii. Inundation period for the 2 -year event is existing plus 2 days. Inundation period for the 10 -year event is existing plus 14 days. e. Lowest building opening must be 3 feet above the 100 -year HWL of the existing wetlands and/or stormwater BMPs. f. An easement must be established over stormwater management facilities, stormwater conveyances, ponds, wetlands, on-site floodplain up to the 100 -year flood elevation. g. Any offsite drainage must be included in the submitted drainage maps and models. Transportation Access Locations: The proposed access locations are appropriately aligned with access points located on the east side of Fenway Boulevard and are adequately spaced from the intersection of 1401h Street. 2. 1401h Street: The applicant is currently showing an access point to the unimproved 1401" Street right-of- way. 1401h Street would need to be constructed (with trunk watermain) to allow for this connection to be made. Cost sharing for the proposed roadway would need to be further evaluated. Sanitary Sewer Service Sewer Improvements: Sanitary sewer service is available from the MCES trunk main along the east side of Fenway Boulevard. A public sewer connection at one of the two MCES sanitary sewer manholes would need to be extended into the proposed site with public drainage and utility easements provided. A permit would need to be provided by MCES for connection to their facilities. Individual private services would need to be extended to each of the three proposed buildings from the newly constructed public 8" main extended from the MCES 42" interceptor. Water Service 1. Watermain Improvements: Water service is available by connecting to the existing 12" watermain located along the east side of Fenway Boulevard. An 8" public watermain will need to be extended west into the site with public drainage and utility easements provided. Individual water services will need to be extended to each of the three proposed buildings. Thank you for the opportunity to comment on this concept plan.
