<br />. <br /> <br />e <br /> <br />Appendix - Arden Hills Water Quality Task Force - June 2000 <br /> <br />to project planning, Consider purchased easements in context of Water Management Plan. <br />Execute purchases in a timely fashion to avoid excessive costs. <br />Maximize long term benefits to cost by using Metro Council BMP's and RCWD infiltration <br />practices in the Water Management Plan, <br />Use the Water Management Plan as a guideline to identify resources and techniques for <br />improvements to areas with direct pipe discharges. <br />Resources: <br /> <br />Some projects will require additional engineering and planning reviews per Water <br />Management Plan. Reconstruction costs may be slightly higher for upgrading and improving <br />structures like piped outlets directly to lakes and wetlands. Establishment of a standard <br />Citywide BMP would minimize the design costs per project. The Water management Plan <br />process should identify these components. Voluntary dedication should be the preferred <br />method for acquisition of easements. A fmancing method and timeline would be necessary <br />to accomplish these goals. The surface water management fee account and other enterprise <br />accounts are a logical funding choice. <br />8) Recommendation <br />Amend City Ordinances as appropriate to encourage improved water quality practices in <br />development and redevelopment projects and to allow for certain types of landscape and <br />water plantings as natural amendments for water quality purposes. <br /> <br />Method(s): <br />Identify areas of conflict in the Ordinance such as weed control versus water quality <br />amendments. 20 <br />Identify special construction requirements for selected areas of concem identified per the <br />Water Management Plan. For example: Contractors might be required to protect non- <br />vegetated slopes during construction from erosion. Vegetated dikes may be placed within <br />(or at termination of) MN-Dot drainages to slow or capture hazardous material spills along <br />major highway right-of-ways with direct runoff to lake areas. <br />Implementation(s): <br />Use normal ordinance procedures to draft and submit language that would allow <br />aquascaping, and landscaping BMP's. <br />Require Special seed mixes for erosion control on slopes. <br />tit Require use of geotextile matting or other protective measures in addition to silt fencing <br /> <br />20 Potential remedies include amending existing ordinances or a creating new ordinance. The committee's discussion <br />favored creating a new Ordinance that addresses water quality initiatives. This approach would avoid the ambiguities found <br />in existing Ordinances by clearly determining the values of specific plantings. <br />
