Options considered and presented shall. examine the merits of relocating_ project <br />elements to address varying soil conditions and other constraints across the site. if full <br />compliance is not possible due to any of the factors listed below,, the applicant. must <br />document the reason. If site constraints or restrictions limit the full treatment goal, the <br />following treatment design sequence shall be followed: <br />Applicant shall document the treatment sequence starting -with Alternative #1. If Alternative <br />#1 cannot be met. then Alternative #2 shall be analyzed. Applicants must document the <br />specific reasons why Alternative #1 cannot be met based on the factors listed below. If <br />Alternative #2 cannot be met then Alternative #3 shall be met Applicants must document <br />the specific reasons _why Alternative #2 cannot be met based on the factors listed below. <br />When all of the conditions are fulfilled within an alternative, this sequence is completed. <br />Volume reduction techniques considered shall include, infiltration, & rainwater <br />harvesting, and canopy interception & evapotranspiration and /or„ additional techniques <br />included in the MIDS calculator and the Minnesota Stormwater Manual. <br />Higher priority shall be given to BM-Ps that include volume reduction.
