No building permit shall be issued for a site until the owner of the site or his authorized agent has submitted a stormwater drainage plan, together with all other submissions required under village ordinances. Required stormwater drainage plans shall be submitted for review and approved prior to the start of construction work or grading activities. Stormwater drainage plans shall be required for all work on any site requiring a building permit except the following:
(a) Interior work;
(b) Roof maintenance or repair (as long as the volume, rate and direction of runoff are not altered);
(c) Any other work that does not make, or propose to make, any change to the exterior dimensions at grade level of the structures on the site; increase impervious area on the site or change the volume, rate and direction of runoff.
All stormwater plans must reflect conformance with all applicable laws and best engineering practices. Such plans must be approved by the village engineer before any demolition or construction work may commence.
The appropriate unit of the building permit application must be completed and approved as provided in section 6-62 of this chapter for any recontouring or grading work to be done even if no demolition or construction work is contemplated.
All plans must be prepared and sealed by a licensed engineer. (Ord. 0-09-09, 4-20-2009)
