35 percent impervious surface plan OK'd by Afton commission

The last month has seen the findings of WSB & Associates' hydrologic study bounce back and fourth between the Afton City Council and the Afton Planning Commission and it has finally come to a stop.

The study was originally presented at the December meeting of the Commission before being passed onto the Council because of uncertainty of what steps to take with the information.

The study analyzed the effects a 35 percent impervious development area, specifically the 69.7 acre agricultural area located at the southeast corner of the intersection of Manning Avenue South and Hudson Road South, would have on the receiving wetlands in regards to water run-off.

The study concluded that there would be a slight rise in elevation of between .06 and .07 feet at both the FAL-31 Wetland and the FAL-32 Wetland, for any given event, meaning any occurrence of precipitation, however this is not an exponential increase since the run-off levels will eventually level off due to the dry periods and the required mitigation that will occur at a neighboring drainage pond.

After recommendation from the Council, the Commission was presented with an ordinance amendment at their Jan. 5 meeting which stated the allowance of a 35 percent impervious surface area in the Industrial District, as long as it is mitigated to meet city requirements.

After some discussion about whether or not the amendment would remain consistent with current city requirements, the commission approved the amendment with a 4-1 vote, commissioner Barbara Ronningen dissenting.

The commission will next give their recommendation to the council.
