<br />SHEET 4 DISCUSSION <br /> <br />Engineering (15%)................... 52.400 <br /> <br />SUB-TOTAL $402. 100 <br /> <br />The improvements shown on this sheet consist of the construction of a 100-year <br /> <br /> <br />detention facility upstream of Caley Avenue. The lower end of the site is presently <br /> <br /> <br />occupied by the KBRQ radio station transmitter with the upper area occupied by <br /> <br /> <br />Southwood Park. owned by the South Suburban Metropolitan Recreation and Parks Dis- <br /> <br /> <br />trict (SSMRPD). The facility will alter the existing topography to provide 100- <br /> <br /> <br />year frequency detention and will allow for recreation use in the reservoir area. <br /> <br /> <br />The design of the detention facility should be coordinated with the SSMRPD. <br /> <br />C. Site Acquisition (17.5 Ac.),....,..,...................,.............$437.500 <br /> <br />TOTAL CONSTRUCTION COST $839.600 <br /> <br />D. Annual Operation and Maintenance.....................................$ 8.900 <br /> <br />Initially. ungated releases from the detention facility will be discharged <br /> <br /> <br />into South Pennsylvania Street (Sheet 5). After the storm sewer is constructed <br /> <br /> <br />along South pennsylvania Street. the outlet pipe can be connected directly into the <br /> <br /> <br />storm sewer (see Sheet 8). eliminating street flows caused by releases out of the <br /> <br /> <br />pond. Local runoff below the facility will generally be contained in the streets <br /> <br /> <br />with the exception of the reach between Logan Street and Grant Street. Any <br /> <br /> <br />flooding in this area will be broad and shallow with minimal damages. <br /> <br />The need for a local collector system along Grant Street has been identified. <br /> <br /> <br />This is to intercept local drainage and spills from a designated spill area along <br /> <br /> <br />the Denver Highline Canal at Grant Street and Caley Avenue. <br /> <br />Cost of Proposed Improvements <br /> <br />A.
