CIP 7A-STORM SEWER TRUNK LINE, SOUTH OF MONTANA Schedule: 2017 Estimated Cost: $1,720,000 This project will replace the existing storm sewer trunk line parallel to South 1st Street south of approximately Montana Avenue. The existing storm sewer trunk line is a 42-inch x 48-inch box culvert. This system is immediately downstream of CIP 6 and additional capacity will be required following completion of CIP 6. This project will install 1,140 feet of 4-feet-deep and 5-feet-wide box culvert to provide capacity for the 10-year peak flow of 354 cfs. Because portions of this project are located outside right-of-way, an easement will be required. CIP 78 -STORM SEWER TRUNK LINE, SOUTH OF MONTANA -PARALLEL PIPE Schedule: 2017 Estimated Cost: $520,000 An alternative to replacing the existing 42-inch-wide by 48-inch-high box culvert is to install a parallel 48-inch-diameter pipe. This project would install approximately 1,150 feet of 48-inch pipe, with an upstream connection to the existing system and discharge to the open ditch downstream of the box culvert. Because portions of this project are located outside of City right-of-way, an easement will be required. CIP 8 -STORM TRUNK LINE, MONTANA TO PENNSYLVANIA Schedule: 2017 Estimated Cost: $470,000 This project will replace the existing stormwater conveyance parallel to South 1st Street between Montana and Pennsylvania Avenues. This system is immediately downstream of CIP 1 and also downstream of CIPs 2, 4 and s. Following completion of these upstream projects, this section of the stormwater system will need to have increased capacity for the 10-year peak flow of 186 cfs. This project will install 1,050 feet of 48-inch-diameter pipe. Because portions of this project are located outside right-of-way, an easement will be required. CIP 9 -HOFFMANVILLE CONVEYANCE Schedule: 2017 Estimated Cost: $300,000 Currently no stormwater conveyance exists in South 2nd Street between West Hoffmanville and West Wyoming Avenues. This project would construct 600 feet of 12-inch-diameter pipe in S 2nd Street and the alley north of West Hoffmanville Avenue, and 600 feet of 24-inch-diameter pipe in South 1st Street and East Hoffmanville Avenue. CIP 10 -NORTH 1ST STREET, WASHINGTON TO NEVADA Schedule: 2017 Estimated Cost: $430,000 This project will replace the existing stormwater conveyance parallel to and within North 1st Street between Washington and approximately East Arizona Avenues. The new pipe will connect to the existing 36-inch pipe installed in 2005. This system is immediately downstream of the connection of CIP 4 and CIPs 2 and 5 connect to this section of the stormwater system. Following completion of the upstream projects, this section of pipe will need to have additional capacity for the 10-year peak flow of approximately 170 cfs. This project will install 900 feet of 42-inch-diameter pipe. Because portions of this project are located outside right-of-way, an easement will be required. June 15, 2016
