<br />MOUNDS VIEW PLANNING COMMISSION <br />RESOLUTION NO. 229-88 <br />PAGE TWO <br /> <br />. <br /> <br />WHEREAS, the discharge rate, storm water storage volume, <br />and the wetland's flood height will not have a substantial nor <br />significant adverse impact upon the wetland; and <br /> <br />WHEREAS, the City's engineering consultant has reviewed <br />the phosphorus calculations for the development per City Code <br />Chapter 48.06, Subd. 3(A)2, and found it to not be in conformance <br />with the Code requirements; and <br /> <br />WHEREAS, the developer has suggested an alternative method <br />for calculating the phosphorus stripping; and <br /> <br />WHEREAS, the Planning Commission would recommend <br />evaluating the phosphorus stripping capabilities of a wetland for <br />both the critical storm event and the average storm event; and <br /> <br />WHEREAS, the City's engineering consultant has reviewed <br />the alternative phosphorus stripping model and found it to be <br />acceptable in calculating an average storm event with some <br />changes in the input assumptions; and <br /> <br />. <br /> <br />WHEREAS, the Planning Commission would recommend to the <br />City Council that the "Walker Method" suggested by the developer <br />is an acceptable method of calculating the phosphorus stripping <br />capacity of a wetland for an average storm occurrence with some <br />changes in the input assumptions; and <br /> <br />WHEREAS, the Planning Commission would further recommend <br />that if this methodology were chosen to supersede the ordinance <br />requirement using the Ramsey Soil and Water Conservation District <br />formula, the model should be modified or another found to assess <br />the phosphorus stripping for a critical storm, therefore, <br />ensuring that the analysis would produce the most conservative <br />estimate; and <br /> <br />WHEREAS, the two analyses gathered, phosphorus stripping <br />in a wetland for an average storm event and critical storm event, <br />should be reviewed to assess the overall quantifiable affect of <br />the proposed development against the existing wetland; and <br /> <br />WHEREAS, the Planning Commission recommends to the City <br />Council to review the standard set in 48.06 (3)(A) for phosphorus <br />stripping and recommends that the standard should be that for a <br />fully developed watershed the wetland alteration shall not result <br />in a net decrease in phosphorus stripping capacity as compared to <br />the predevelopment conditions of the wetland; and <br /> <br />. <br /> <br />WHEREAS, the Planning Commission further recommends that <br />the City Council add to 48.06, Subd. 4, the term "phosphorus <br />stripping" to allow the City Council to place conditions related <br />to that subject upon an alteration permit approval; and <br />
