The City acquired the property located at 2020 Hoover Avenue, former site of Suncoast Bus
Company, with the intent to include the property in the Westside InfII Transit Oriented
Development (WI-TOD) Housing Project. The site contains an underground storage tank
system. Neither the City nor the WI-TOD project will be using the tank, and thusly, the City is
mandated by the County of San Diego, Department of Environmental Health (DEH) to apply
for permanent closure and removal of the tank. Although not part of the requirements of the
DEH, this project includes the removal of the storm water interceptor system,.
On March 21, 2012 the DEH inspected the underground storage tank (UST) located at 2070
Hoover Avenue and concluded that the permanent closure requirements for the UST were not
met.
On April, 25, 2012, the DEH approved an extension of the compliance due date so that the
City could comply with the requirements of the Public Contract Code wherein it is necessary to
publically bid the project.
In June of 2012, the Engineering staff was assigned the task of publically bidding the project.
In July of 2012, site visits were conducted and a consultant was hired to prepare the
specifications for the project. Staff received the specifications for review in September of 2012
and the project was advertised.
In October 2012, the DEH verbally advised the City that due to the length of time in achieving
permanent UST closure, administrative action by the DEH is being considered,which could
include mandated compliance dates for project completion.
On October 30, 2012, four bids were received and opened for the removal of an underground
storage tank system and storm interceptor system at 2020 Hoover Avenue. The lowest
responsive bidder was West -Tech Contracting with a proposed bid amount of $32,625.00.
Additionally, Additive "A" in the amount of $4,620 for backfill of excavated site was selected to
be awarded. The total contract amount is $37,245.The bid opening information sheet and the
cost proposal worksheet for the three lowest bidders are attached for your information.
Staff is requesting that Council authorize an appropriation from the un-appropriated General
Fund Balance to complete this project. Use of the General Fund is necessary as time is of
essence as administrative action is underway by the County DEH due to the length of time
needed to comply with mandated required remediation and permanent closure requirements
at the site.
Another factor complicating this project is that the soil surrounding the area of the tank
removal must test clear of any pollutants. Should pollutants be discovered, it will be necessary
to over -excavate the site to the extent that the soil is free of pollutants. If over -excavation is
necessary, additional back fill will also be required. Based on earlier testing of the site, staff
does not anticipate a finding of a large amount of contamination but because time is of
essence, staff requests that Council approve a total budget of $85,000. This amount shall
fund the contract amount of $37,245 and shall fund any unforeseen changes to the contract,
construction management & inspections, and soil sampling & materials testing. It is also
requested that Council authorize the City Manager to execute the contract and approve any
and all change orders not to exceed the total approved budget.
Staff checked the provided references for West -Tech Contracting, Inc and found that they are
qualified to perform the work as detailed in the specification.
