The Department of Public Works is seeking approval of a storm sewer easement from Winnebago County that will run through a portion of the property at 1135 West 20�h Avenue and through the property at 525 West 20ih Avenue. ANALYSIS The Glatz Creek Watershed has historically experienced severe flooding during rainfall events most notably 20�h Avenue between South Park Avenue and Oregon Street. In 2009 the Storm Water Utility began an in depth analysis into this watershed and a consultant was hired to prepare a storm water management plan which resulted in construction of a relief storm sewer in 2013. The Department of Public Works has been working with Wittman Regional Airport staff to have the next phase of the relief storm sewer constructed in conjunction with a taxiway reconstruction project on the airport property which is scheduled to begin in 2015. The Department of Public Works has reviewed the proposed easement and noted that it will not conflict with city utilities and will coordinate with Winnebago County to have appropriate documents signed and recorded at the Winnebago County Register of Deeds. FISCAL IMPACT None anticipated. RECOMMENDATION The Plan Commission approved of the request at its July 7, 2015 meeting.

Applicable Ordinance Provisions: I`� Property Location and Background Information: The adjacent subject parcels are a combined 611.17 acres in size and located along West 20th Avenue and Knapp Street at Wittman Regional Airport. The Department of Public Works is seeking approval of a storm sewer easement from Winnebago County that will run through a portion of the property at 1135 West 20`h Avenue and through the property at 525 West 20`" Avenue. Analysis: The Glatz Creek Watershed has historically experienced severe flooding in moderate to severe rainfall events. Most notably, 20�h Avenue between South Park Avenue and Oregon Street has historically suffered very severe flooding. In 2009, the Storm Water Utility began an in depth analysis into the Glatz Creek Watershed by hiring McMahon Associates, Inc. to prepare a storm water management plan for the entire watershed. As a result of the analysis performed, the Department of Public Warks began the construction of a relief storm sewer for the Glatz Creek Watershed in 2013. This wark coincided �vith the reconstruction of 23`d Avenue from Montana Street to Doty Street, Doty Street from 23`d Avenue to 24`h Avenue and 24`h Avenue from Doty Street to Lake Winnebago. The next phase of the relief storm sewer will extend into Wittman Regional Airport. Staff from the Department of Public Works has been working with staff from Wittman Regional Airport and OMNNI Associates, Inc. to have the next phase of the relief storm sewer constructed as part of a taxiway reconstruction project on the airport. This project is scheduled to begin following EAA AirVenture 2015. In order to construct the storm sewer through Wittman Regional Airport, the City needs to obtain a storm sewer easement from Winnebago County. The proposed 30 ft wide easement will run north to south along a portion of the east property line starting near the end of Knapp Street at 1135 West 20`h Avenue and run west to east through the property at 525 West 20�h Avenue, ending at the parcel's east property line. The Department of Public Works reviewed the proposed easement and reported that the easement will not conflict with city utilities. The Department of Public Works will coordinate with Winnebago County to have appropriate easement documents signed and recorded at the Winnebago County Register of Deeds. RECOMMENDATIONS/CONDITIONS Staff recommends approval of accepting the proposed storm sewer easement as requested. The Plan Commission approved of accepting the easement as requested. The following is the Plan Commission's discussion on this item. Mr. Slusarek presented the item and reviewed the site and surrounding area as well as the zoning classifications in this area. He discussed the measures taken to improve the storm water management plan for the Glatz Creek Watershed and reviewed the site plan for the proposed easement. He further stated that the area suffered from severe flooding issues and reviewed a map depicring the Glatz Creek Watershed. Mr. Hinz stated that the water flowage runs from the west to the east in the city and questioned how this storm sewer improvement would help with flooding issues on the east side of the airport. James Rabe, Civil Engineer Supervisor, explained the flooding concerns on 20`� Avenue which is severe from South Park Avenue to the railroad tracks and how this storm sewer easement from Knapp Street extending down 20�h Avenue will reduce the issues in this area. Mr. Hinz inquired if this would have any impact on properties to the east of the airport. Mr. Rabe indicated that it would reduce the flooding on 20�h Avenue and this work would coincide with reconstruction already completed on 23`d & 24`� Avenues and Dory Street. Motion by Gray to approve the acceptance of a storm sewer easement at 525 & 1135 W. 20`� Avenue. Seconded by (/ajgrt. Motion carried 8-0.
