RECOMMENDED ACTION:
Adopt Resolution No.1305 accepting bids and awarding the contract to
Layfield Environmental Systems Corporation for the Maerkle Reservoir Cover Inspection, Cleaning,
Repair, and Rainwater System Upgrade, Project No. 5005.
ITEM EXPLANATION:
Maerkle Dam is located near the eastern edge of Carlsbad, approximately two miles north of
Palomar Airport Road. The reservoir behind Maerkle Dam is a 200 million gallon potable water
storage facility with a flexible polypropylene floating cover and an asphaltic concrete liner. The floating
cover was installed in 1998 to meet California Department of Health Services (CDHS) requirements.
The cover is 45 millimeters thick and covers a surface area of about 16 acres when the reservoir is
full. The major components of the cover include floats for buoyancy, an access system made up of
19 hatches, and a rainwater removal system made up of eight in-sump pumps and approximately
2,000 feet of discharge hoses.
In 2006, CDHS performed an inspection of the cover and requested certain repair and maintenance
activities be undertaken. Project No. 5005 will meet the requirements of the CHDS through an
inspection, cleaning, and repair of the floating cover and the replacement and upgrade of the
rainwater removal system. The rainwater system has reached its useful life and is experiencing hose
leaks and pump failures. Since the reservoir contains treated drinking water, failures of the rainwater
systems could cause water contamination and expose Carlsbad Municipal Water District (CMWD) to
CDHS actions that could result in fines for non-compliance to State health requirements.
On June 19, 2007, through the adoption of Resolution No. 1299, the CMWD Board authorized the
advertisement to receive bids for the Maerkle Reservoir Cover, Project No. 5005.
On August 7, 2007, one (1) sealed bid was received for the construction of this project, which is
summarized below:

The Engineer's Estimate for this project is $140,000. The bid submitted by Layfield Environmental
Systems Corporation is 20.5% higher than the Engineer's Estimate. The work involving the floating
cover is very specialized. As such, there are very few contractors with experience in this field.
Therefore, requesting new bids will not result in an increased number of bidders or a lower
construction cost.
Staff has completed its review of all documents and finds that they are' in order. Therefore, staff
recommends that Layfield Environmental Systems Corporation be awarded the contract.
