Title
FINAL ACCEPTANCE AND FINAL PAYMENT OF CONTRACT K-1718-64 WITH INSITUFORM FOR THE ST. JAMES PARK SECTION 5 ADDITION 48-INCH REINFORCED CONCRETE PIPE STORM SEWER REHABILITATION PROJECT.
Body
BACKGROUND: The project involves cured-in-place-pipe repairs to approximately 364 linear feet of a 48" reinforced concrete pipe (RCP), which is located beneath a detention pond in the St. James Park Section 5 Addition. The existing RCP has leaking pipe joints and cracks that have caused the pond to be drained. Attempts have been made to fix specific locations along this length of pipe in the past, only to have it occur elsewhere along the length of the pipe. The pipe and detention pond were constructed in 2004 by the private developer of St. James Park Addition. According to the drainage report for St. James Park Section 3 prepared by Carter-Burgess Engineering for the developer, the 48" RCP was designed to carry the 2 to 10 year storms to the creek to the east of the development, and concrete overflow flumes were constructed to carry the 25-year, 50-year, and 100-year storms to the detention pond. This was part of a drainage solution for both St James Park Section 3 and Cedar Lake Estates in 2004.
