Item No: 7G Meeting Date: January 9, 2012 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 7885, Considering Stormwater Infiltration Program Appeals in Area E of the Street and Utility Improvement Program Background: Area E of the Street and Utility Improvement Program (Program) is in final design and scheduled to begin construction in spring 2012. The Stormwater Infiltration Program (SIP) is the City’s approach to meeting the stormwater management rules and regulations when reconstructing streets associated with the Program. The SIP is comprised of constructing stormwater infiltration basins in the City-owned right-of-way. The City also established a process for property owners to appeal the location of an adjacent infiltration basin proposed in front of their property. A specific set of physical and hardship parameters must by met for the City to consider the appeal. The City has provided adjacent property owners in Area E the following opportunities to become aware of the City’s intent to construct the infiltration basins in front of their property and to learn more about the proposed basins: Nov. 7, 2011: Notice sent to adjacent property owners (with SIP FAQ handout – see attached) Nov. 21, 2011: Public information meeting for stormwater infiltration basins Nov. 7 - Dec. 9, 2011: Appeal period and opportunity to ask questions of City staff Dec. 9 - 19, 2011: City staff reviews submitted SIP appeals and develops recommendation Dec. 19, 2011: Streets & Utilities Committee considers appeals & provides recommendation Jan. 9, 2012: City Council considers SIP appeals The preliminary design identified 94 locations (adjacent to 92 properties) as candidates for infiltration basins in Area E. Of these 94 locations, 13 have been eliminated due to design issues that have been discovered during final engineering design. The City received 11 SIP appeal forms, with four appeals part of the 13 that were eliminated, leaving seven appeals to consider. A copy of the appeal forms and infiltration basin location map are attached to this report. Discussion: A discussion of the seven appeals for City Council consideration follows below. Many of these appeals had similar concerns, including the potential for water in the basement, tree concerns, access to outbuildings, and not wanting the basin to encompass the entire boulevard area. A copy of each appeal form is attached to this report. 5155 Eastwood Road (Paul Thompson) – SIP#34 The property owner is appealing for the following reasons: 1. aesthetics; 2. worried about water in basement (surface runoff and ground water); 3. large maple tree in boulevard; and 4. access from street to future shed in backyard. • There is no evidence that infiltration into the ground from the basin storage will cause a change in groundwater elevation.
