Home My WebLink AboutItem I-B PLAN COMMISSION STAFF REPORT JANUARY 04, 2011 ITEM I-B: CONSENT AGENDA ACCEPT STORM SEWER EASEMENTS AT VARIOUS LOCATIONS ON PROPERTY LOCATED BETWEEN KOELLER STREET AND THE TIPLER SCHOOL AREA STORMWATER DETENTION BASIN GENERAL INFORMATION Petitioner Owner: City of Oshkosh Department of Public Works Landmark Limited Partnership III -300 S Koeller St Donald Olson -251 S Westfield St Greg Roberts -255 S Westfield St Xiong/Tong Yang/Mai Yang Pao -240/250 S Westfield St Action Requested: The Department of Public Works is requesting acceptance of multiple storm sewer easements running between South Koeller Street right-of-way east to the Tipler School Area Stormwater Detention Basin (TDB) located over property at 300 South Koeller Street, 251/255 South Westfield Street and 240/250 South Westfield Street. Applicable Ordinance Provisions: N/A Property Location and Type/Analysis: The Department of Public Works is requesting the acceptance of multiple storm sewer easements, temporary and permanent, located between the the 300 Block of South Koeller Street and the Tipler School Area Stormwater Detention Basin (TDB) running around the south and east sides of Landmark Plaza, along the north side of 251/255 South Westfield Street, and along the north side of 240/250 South Westfield Street. This area is located within the Campbell Creek watershed and was recommended to be reconstructed in combination with upsizing the storm sewer within the Watershed Study. Currently, the existing drainage system is a combination of underground pipes and open ditches. The proposed series of easements will allow for the construction of a system with increased capacity and provide area necessary for maintenance and construction access. The visible area above/adjacent to the planned box culvert installation on the Landmark Plaza property will be a stone riprap lined channel, which will serve as an overflow channel to allow additional storm water capacity as overflow, when needed. The area over and adjacent to the residential developments will be be restored to existing grass or driveway. The Department of Public Works will work with the property owners to have appropriate easement documents signed and recorded at the Winnebago County Register of Deeds. RECOMMENDA TION/CONDITIONS Staff recommends approval of the acceptance of the proposed storm sewer easements as requested. OfHKOfH ON THE WATER MEMORANDUM TO: Members of the Plan Commission FROM: Steven M. Gohde, Assistant Director of Public Works 5""?j DATE: December 27,2010 RE: Accept Easements The Department of Public Works is seeking the acceptance of easements located between Koeller Street and the Tipler School Area Stormwater Detention Basin (TDB) around Landmark Plaza and near the TDB. This area is in the Campbell Creek watershed. The watershed study performed by Strand Associates of Madison recommended the construction of the TDB in combination with upsizing the storm sewer between Koeller Street and the TDB. Currently, the existing drainage system is a combination of pipes and open ditches in narrow easements. The existing stormwater drainage way makes four 90 degree turns. The 90 degree turns reduce the capacity of the stormwater drainage system. The proposed stormwater drainage system is concrete box culvert, varying in size from 3' by 6' to 4' by 6'. The proposed easements allow for the construction of 45 degree angles to help increase the capacity of the system. Additional area is also included to allow maintenance and construction vehicles access to the drainage system. The area above/adjacent to the concrete box culvert through the Landmark Plaza area will be a riprap lined channel. This will serve as an overflow channel to allow for additional stormwater capacity/storage in the event it is needed. The area adjacent to the residential developments will be restored to grass or driveway depending on current use. The acceptance of these easements will allow the new storm sewer pipe to be constructed without any 90 degree bends and provide adequate space for maintenance/construction vehicles to construct and access the system in the future. 2 H:\steveng\PC memo3\easements.doc CP NO CP IS CP 55 CP T5 CP 80 CP 92 TOP NUT ON HYDRANT IN FRONT OF 1'30/180 WESTfClELO STREET -----...,. • L.
