Mounds View Planning Commission June 22, 1988 Special Meeting Page Three • have an option to use that as a measure for a proposed development. He added that the questions of how it would calculate to a critical storm event needs to be evaluated. He also stated the Planning Commission needs to address what method would be used and how the standard would be applied. Mr . Merila stated the existing method does not provide an adequate manner of calculating phosphorus stripping, and a better method is needed. Kay Weseman, no address given, asked if there was another approach to improving phosphorus stripping in a wetland. Mr. Borovsky stated he would be surprised if state of the art phosphorus calculations didn' t show the proposed development would result in improved phosphorus stripping capacity. He added that while that gives an indication of the direction the development would proceed, it does not provide a test of whether it would be good enough or not. He stated the language in the ordinance now is what the test would be. • City Planner Herman stated they are trying to help the City Council decide what direction they want to go, and the issue is both how to get the end result, what model to use as well as the end result itself. Mr. Sabee expressed concern with the total picture and its implications, stating they need a standard that will look at all cases and protect the intent of the ordinance in all cases without necessarily approving the development. Mr. Merila stated he feels there is a better technical method of calculating phosphorus than what is currently being judged, and if Barr has another method, they have no problem complying with that versus the Walker Method. Mr. Merila reviewed his letter of June 22, in response to the June 17 letter from Barr Engineering. City Planner Herman reviewed proposed Resolution No. 229-88 with the Planning Commission. She stated that regardless of whether the development is approved, she would recommend the Coucnil address the proposed change to the wetland boundaries and bring the wetland map current . • There was discussion among the Commissioners regarding setting standards for phosphorus stripping. City Planner Herman read from portions of the ordinance and questioned whether the Planning Commission was already setting standards, and she advised recommending to the Council that they look at the standard rather than giving a definitive recommendation.
