BACKGROUND A property owner recently notified the City that a drainage swale had been placed on his property without his approval and he would like it removed. City staff investigated his claim and determined that the swale was installed on private property as part of the City's 1999 Small Drainage Project. The swale was to be placed on the adjacent City owned parcel to the south but was designed and constructed using the wrong parcel. ACTION TAKEN KPG was contacted to design a new drainage system to allow for the removal of the swale from private property. The design calls for piping the drainage across S. 129th Street and construction of an infiltration system within the Codiga Farms site and adjacent to the roadway. No piped drainage outfalls to the river exist in the area so infiltration is the only available option to dispose of the roadway runoff. The Small Works Roster was consulted and letters were sent to six firms that were qualified for this type of work requesting bids. Three bids were received with Brike Excavating as the low bidder. The bid results are as follows: Brike Excavating Pivetta Brothers Dennis R. Craig $37,697.91 $49,253.00 $49,769.00 Brike Excavating has completed several projects for the City and has performed quality work. BUDGET AND BID SUMMARY (All amounts include sales tax.)
