Site Planning | 19 <br />STORMWATER MANAGEMENT <br />Water features and drainage systems are essential components of development in the district. A mix <br />of ponds, fountains and other water elements provide focal amenities and year round activities within <br />the framework of an environmentally responsible, visually pleasing strategy to manage stormwater. <br />Each site has a responsibility to utilize best management practices (BMP) to pretreat run-off, reduce <br />erosion and encourage infiltration in compliance with City and watershed standards. Water and <br />landscape should be utilized within multipurpose areas that accommodate both active and passive <br />recreational use – the following examples illustrate only a few of many possibilities: <br />1. Pervious pavements, underground <br />storage and other creative techniques <br />should be used to meet BMP standards, <br />particularly in areas where more density <br />is expected. <br />2. Stormwater reuse is encouraged, but <br />not feasible on all sites. Developers <br />should utilize it in their development <br />where feasible. <br />3. Green architecture, expressed through <br />green roofs, gray water recycling and <br />other techniques should be included to <br />reduce the impact of new development <br />on stormwater systems. <br />4. Water feature design should include both formal elements (such as reflecting pools or <br />fountains) and natural/informal forms (such as ponds or fountains) and should explore creative <br />ways to integrate wet landscapes with active, urban spaces. <br />All developments should provide a Chloride Management Plan. Studies (see MCES publication <br />regarding Nine Mile Creek, March 2021) show that chloride (or salt) found in surface waters and <br />shallow aquifers has been increasing over the past 20 years. One source of the river’s chloride is <br />the salt applied to our streets, parking lots, driveways and sidewalks in the winter and results in <br />peak chloride values between March and May. Due to the chloride’s toxicity on the environment, <br />watershed organizations and regulatory agencies have increased their focus on the urban sources and <br />some watersheds are implementing practices for reducing salt applications. <br />Functional and blended stormwater facilities enhance the overall development
