CC Regular Session 7. 1. Meeting Date: 03/12/2019 By: Sean Sullivan, Community Development Information Title: Adopt Resolution #19-067 Approving Purchase Agreements for Land Exchange; Case of PSD LLC Purpose/Background: Public Well Background The City selected the area west of Ramsey Boulevard and generally south of Bunker Lake Boulevard for siting of new municipal wells in the 1990's. Five wells were developed in the area. The area was also selected for development of the COR (formerly known as Ramsey Town Center in the early 2000s). Stormwater Background The City is a member of the Lower Rum River Watershed Management Organization, (LRRWMO) a joint powers association with the cities of Andover and Anoka. The LRRWMO is required to update their plan every ten (10) years by state law. The State of Minnesota updated the requirements for WMO plans prior to preparation of the Third Generation Plan for the LRRWMO. The change included infiltration of the first inch of runoff from all impervious surfaces in an effort to reduce storm runoff entering the system. The Third Generation plan was updated in 2011 and included the requirement for infiltration of the first inch of runoff with the exceptions included in the state law. The infiltration law does allow for creating an infiltration mitigation project outside of any wellhead protection area. The mitigation project must receive an equivalent amount of runoff as the site being mitigated. Multiple development projects were constructed in the COR after the Third Generation plan was adopted and they needed to provide infiltration. However, infiltration is not permitted on their sites. Staff conferred with the LRRWMO and determined that a regional/shared infiltration mitigation basin could be placed in the southeast corner of the COR adjacent to the existing storm water pond. The City collected an infiltration mitigation payment from this project and all subsequent projects in the COR that are in the wellhead protection area. The proposed mitigation area includes an area that was encumbered by drainage and utility easements on the original Ramsey Town Center Plat. The original plat included provision for an emergency vehicle access to Ramsey Boulevard. The route of this access is through the proposed infiltration basin. Since then, a full public roadway has been planned as a result of Highway 10 planning efforts. This route runs along the north edge of the proposed infiltration basin. This connection will be right-in/right-out at Ramsey Boulevard. This route will be constructed in the future when warranted. Part of the infiltration basin is on City owned property and the other part is on PSD owned property. The proposed acquisition will transfer ownership of the portion of the basin on PSD property to the City so that the City can provide perpetual maintenance of the basin. The transfer also includes the proposed right of way for the future road and a remnant piece south of the Medical Examiners building that is too small to develop. Staff has previously been directed by the City Council to negotiate acquisition of the land needed for for stormwater infiltration ponding and road right of way south and east of the Medical Examiner's office.
