Approve Change Order No. 1 to Contract No. C26670A in the amount of $13,546.00 for the Miscellaneous Drainage Project; 2. Authorize the transfer $13,546.00 from contingency to base; and 3. Authorize the Mayor to execute said Change Order No. 1. Background On June 9, 2011, City Council awarded Contract No. C26670A in the amount of $996,972.70 to Tri-Star Contracting II of Desert Hot Springs, California, for the Miscellaneous Drainage Project to improve five locations where nuisance or storm water present risks to the City. Shortly after award of this project, another location was identified where an existing drainage system failed resulting in a large pool of standing water. The standing water was located within the Haystack Greenbelt east of Calico Cactus Lane. Reports that mosquitoes with West Nile Virus were found nearby prompted the Public Works department to find an immediate solution. Tri-star Contracting provided a proposal to construct an underground retention system with a clean -out structure. The City Manager authorized Tri-Star to proceed with the construction of the system. Staff Report Approve Change Order No September 29, 2011 Page 2of2 1 (Contract C26670A) Funding for this change order is within the contract contingency, which has already been approved by Council. Fiscal Analysis The initial contract amount was $996,972.70. This change order will increase the contract amount to $1,010,518.70. The system that was constructed under this change order will require periodic maintenance. The City already has a program for maintaining water retention devices and this location will be added to the program. The maintenance cost increase is negligible.
