R2008-206 AUTHORIZING ADDENDUM ANNUAL SEWER TELEVISING PROGRAM

Home Browse Search

Overview In early 2006, the City Council authorized the prepazation of a new City map based on Geographical Information System software as a way of managing, analyzing and displaying the information the City has on its infrastructure and on the community as a whole. The GIS map will be connected to the City's digital document management system as a way to tie information to addresses or locations. The infrastructure portion of the map includes mapping the sanitary and storm sewers that serve the City and adding in all o f the information the City has on the systems. An accurate map of the City's sanitary and storm sewer infrastructure is a crucial foundation to the preparation of the sanitary sewer and storm water master plans currently underway. Current Project Status At the April 7, 2008, meeting of the City Council, staffproposed an increase to the annual televising project authorization from the normal$250,000 allocation to $400,000. The increased funding was proposed to enable a significant increase in manhole and sewer main inspections necessary to assure the accuracy of the line maps being prepazed by EIU along with inspecting a portion of the large diameter critical sewers owned by the City. To date,over 75,000 lineal feet of large diameter sewers have been inspected. This data is still being reviewed. A brief report from TSI has been included herein for Council's information. ' GIS Map Preparation The mapping and review work is proceeding on track to be completed by mid summer. A major component of the map review has been provided by TSI in their ability to televise pipes to deternune their location and clear up many areas of confusion related to the location of the City's sewer system The current City sewer maps were originally prepared in the 1930's with various improvements over the years and have been found to be very inaccurate in some instances. As the new map is put together,the investigations provided by TSI and the map quality review provided by BGM have been crucial to assuring accuracy and clearing up longstanding problems with the old map. A letter regarding the mapping process is included herein. To date, approximately 20% of the sanitary and storm sewer infrastructure map has been completed. The investigations necessary to continue producing an accurate map are outpacing the needed funding estimated in the original authorization. Approximately$130,000 in authorized funding remains in the televised inspection project,the remaining funding needs to be reserved for emergency inspections and to review the sewers under the streets proposed for reconstruction in 2009. An additional$160,000 is proposed for televised inspections to enable the map preparation to continue to move forward. It must be reiterated that the original funding proposal was an estimate of the investigation work needed to assure an accurate map. Without adequate funding, the map preparation will slow considerably or stop and the accuracy will decrease significantly. POTENTIAL OBJECTION: There are no known objections to this resolution. Page�2
