Public Works Committee 6. 1. Meeting Date: 09/16/2014 By: Bruce Westby, Engineering/Public Works Title: Consider drainage concerns at 5220 - 156th Lane NW Purpose/Background: The property owner at 5220 - 156th Lane NW is concerned with surface water drainage in the rear yard, particularly as related to the long periods of standing stormwater being experienced this year and the impact it is having on vegetation and trees in the rear yard and in Woodland Green Park located directly behind the property. All communications to date have been through the property owners father, Mr. David Full. The drainage issues on this property have been discussed by the Public Works Committee in the past. Attached is a case from the July 19, 2011 Public Works Committee meeting at which this drainage issue was first discussed. The two attachments referenced in the 2011 case are also attached to this case. These include an area overview exhibit which shows the existing stormwater infrastructure from Wildlife Sanctuary east to the Rum River, as well as a lot detail which shows existing easements and drain field locations. Minutes from this meeting, as well as minutes from the October 11, 2011 meeting where the proposed resolution was discussed, are also attached. As a result of the two 2011 cases, the City paid to relocate the septic system drain field to a location outside the area that is flood prone. Since this work was completed, the property has changed hands and the new owner has contacted the City and is requesting that their drainage concerns be addressed. Also attached to this case is a figure showing updated aerial photography of the general area. Public Works Superintendent Riemer recently inspected the storm sewer infrastructure in this area while it was raining to see if any storm sewer or culverts were plugged. No issues were noted. Mr. Full invites all elected officials and Staff to meet at his daughters property starting at 4:30 pm on Tuesday, September 16th. Mr. Full would like City Council and Public Works Committee members to review and discuss the drainage concerns on his daughter's property prior to discussing this in more detail during the September 16th Public Works Committee meeting. He feels this would be beneficial for those Council members who are on the Public Works Committee to know before the meeting. Staff recommends visiting the site before the regular Public Works Committee meeting, and to meet in the Woodland Green Park lot off of 155th Lane NW at 4:30 pm. Staff will then begin the site visit by discussing the existing drainage infrastructure before moving to review the issue in the rear yard of 5220 - 156th Lane NW. Staff will also stake the existing 25-foot wide drainage easement prior to the site visit so it is clear where the limits of the existing easement are in relation to the standing water and the house itself. Timeframe: Approximately 15 minutes for discussion (after the field trip). Observations/Alternatives:
