Schedule of activities that are part of the management and maintenance for the <br /> . establishment of vegetation. <br /> Survey Requirements <br /> As mention p�eviously the submitted plan shows a buffer around the wetland adjacent to the <br /> proposed home sites. Ta be in compliance with the submittal requirements of the ordinance <br /> the survey needs to be updated to reflect a 35 foot buffer and 20 foot setback from buffer <br /> around the entire perimeter of#he wetland areas within the plat. <br /> Restriction and Covenant for Wetiand and Buffer � � <br /> Per Section 78-15i 1 of the wetland ordinance the owner shall record restriction and covenants <br /> over the wetland and buffer with the property chain of title. A form with the language for the <br /> . Restriction and Covenants is available from the City. <br /> Wetland Buffer Markers � - <br /> Per Section 78-1612 due to this being a new devefopment the developer must place markers <br /> on the upslope edqe of the buffer edge at least every two hundred feet,subject to City <br /> approval. The developer shall submit a location plan for the signs in hard copy format and a <br /> CAD or GIS(electranic)format in Hennepin County coordinates and wil!use uniform markers <br /> provided by the City. Under the ordinance the City can charge a reasonable cost for the <br /> . markers. � � <br /> Treatment Requirements <br /> Per Section 78-1605 the wetland ordinance requires that phosphorus loadings are limited to <br /> predevelopment loading times 2 or 0.28 Lbs/AdYr. Bounce in the wetland must be maintained <br /> at or below existing conditions plus 4.5 feet. <br /> Currently the raingardens are the primary treatment feature. These are located near the . <br /> wetlands in the buffer. In order to be affective raingardens need ta have 3-foot separation <br /> from groundwater and t�e ability to draw down in 48-hours at a maximum depth of 2-feet. <br /> Due to the position of the raingardens near the wetlands they likely do not have the required <br /> .separation from groundwater. In addition the soil survey indicates Glencoe soils in the area of <br /> �the raingardens which is a silty clay loam soil#hat is very poorly drained. 8oring(s}should be <br /> canducted to determine the best location and appropriate size of the raingardens and confrm <br /> that they will be an affective veatment measure for this area. Soi1 correction may be necessary <br /> to make raingardens affective. lartce Hoff of Bonest�oo will be completing the water quality <br /> and quantity review and should be copied on future submittals, <br /> PageZof3 <br />
