conducted by agents of the RCWS by observation and inspection after a specific <br />adequate rainfall event. Basically they travel out 36 to 48 hours after an event and if <br />water is gone, basis in working as the design is full infiltration within 48 hours. <br />Technically, we are subject to the enforcement penalties under Rule K for non- <br />compliance. Practically, if we wish to petition the district for a change or variance, the <br />first step would be to ensure we are in compliance with all permits —which we are not. <br />That said, Public Works is working on ensuring functionality of all gardens <br />2. We have at least one resident, and very likely more, who do not wish to care or have a <br />rain garden in their yard (our easement). <br />3. We have signed maintenance agreements with RCWD which, in 15 to 20 years' time, will <br />require digging up some or all of the garden to remove sediment and/or debris and <br />replant. Depending on the design, configuration, and components the "bill" for the <br />approximate 600 gardens will range between $600,000 and $1 million. <br />4. We have not but should, develop a policy for rain gardens that covers the following <br />areas; <br />a. XX <br />b. XX <br />c. XXX <br />d. XX <br />e. XXX <br />History Specific to RCWD and Mounds View: <br />As detailed earlier, Watersheds were created in 1955 and RCWS in 1972. Somewhere (research <br />pending) between 1972 and 2008 Rule C was created which set the design standard for storm <br />water runoff at 2.8 inches and included public linear projects (streets). <br />Late in 2015, this rule was amended by RCWD to .55 inches and the current area of public linear <br />projects in place was exempted with only expansion of the street (if it occurred) being required. <br />Of note is the Minnesota Pollution Control Agencies effort starting in 2009, based on legislation <br />and accompanying allocation of funds, created the Minimal Impact Design Standards (MIDS) <br />work group in 2011. Prior to MIDS, the goal of storm water management was to move it off the <br />landscape as quickly as possible to reduce flooding to the present day of keeping the raindrop <br />where it falls. <br />The MIDS Group held meetings around the state in 2011 2012 and 2013 with the culmination of <br />their efforts resulting in a series of documents/guides — one of which set the standard of .55 <br />inches over impervious and 1.1 inches over impervious. It is uncertain where the 10,000 sq. ft. <br />exemption threshold was/is established but the current RCWD threshold for storm water <br />management triggers off the 10,000 of new area. <br />2 <br />
