Portage approves on-site stormwater plan for 7 Brews development
Loading...
Summary
Portage council approved an on-site stormwater drainage plan for the proposed 7 Brews development after the applicant’s representative and the project engineer said the design would keep the site’s release rate unchanged and add a bioswale and ponding system.
Portage council voted to allow the proposed 7 Brews development to discharge stormwater at the site’s existing rate after hearing from the project representative and the engineer who reviewed the design.
The council’s chair opened the discussion and invited the developer’s representative to present. “We’re requesting that we discharge at the existing rate on-site,” said Matt, the project’s representative, describing a plan that includes a bioswale and a central ponding system to handle runoff. Mel, an engineer with Christopher Burke Engineering, told the board the plan “simply detains the difference between what was existing for the development and the new impervious area,” adding that “the release rate from the site doesn’t change, and we support that.”
The change the applicant sought was to meet the existing on-site release standard rather than a reduced (lower) release requirement; the engineering explanation to the council was that detention and the added bioswale would offset the new impervious area so downstream flow rates remain the same. The applicant and the firm both described the bioswale and ponding system as the primary on-site controls.
A motion to approve on-site stormwater and drainage for 7 Brews was made by a council member and seconded by the chair; the council approved the motion by voice vote. The council did not specify additional conditions in the recorded discussion.
Staff and the project representatives said the site will implement the bioswale and the ponding system as described; no construction timeline was provided during the meeting. The approval allows the project to proceed with the approved drainage approach, subject to any permitting steps the city or IDEM requires.
