BATH — Hyde School’s plan to build a new dormitory ran into a speed bump Tuesday at the Planning Board.
The private high school’s request for site plan approval was tabled while the board awaits more information on how Hyde will mitigate storm water flow from the new building into the city’s combined sewer system.
Bath Public Works Director Peter Owen will work with project consultants on that plan, which is expected to return to the Planning Board on Dec. 6.
The 17,000-square-foot building would replace an existing dorm built in 1975, which Hyde Chief Financial Officer Alyssa Hemingway said has “met and exhausted its useful life.”
The Campus Drive building would house up to 56 students in 28 rooms, and have four faculty apartments. The capacity of the existing dorm – demolition of which could begin next June – is 34 students and two faculty apartments, Hemingway said.
The new dorm could be complete by spring 2013.
Town Planner Andrew Deci noted in a memo to the Planning Board that the replacement dorm would increase the intensity of use on the property. Increased sewage flow would be one impact, while the control of storm water on the site would be another issue.
“Exclusive of some issues related to storm water management, the applicant has resolved the concerns that staff has,” Deci said.
Prior development and the site’s topography have limited opportunities to treat and retain storm water there, Deci explained. The site plan would direct the water to the south, toward Academy Green, where it flows to a combined sewer system.
While there is currently capacity to treat day-to-day waste water volume in dry weather conditions, Bath’s sewer collection system suffers from storm water inflow during rain storms, which clogs the pipeline system and causes flooding.
