RECOMMENDED ACTION:
Adopt Resolution No. 2011-200 accepting bids and awarding the contract to Sierra Pacific
West for the Calavera Hills Wastewater Treatment Plant Demolition Project, Project No. 5507.
ITEM EXPLANATION:
The Calavera Hills Wastewater Treatment Plant was constructed in 1980 as a part of Carlsbad Tract
No. 76-12 (Calavera Hills Development). It is located on the northwest side of Tamarack Avenue,
between Pontiac Drive and Edinburgh Drive. The Treatment Plant was to be used once the City of
Carlsbad's flow rate at the Encina Water Pollution Control Facility (EWPCF) reached 5.45 MGD.
However, the EWPCF was subsequently expanded and the Calavera Hills Wastewater Treatment
Plant was not placed in operation. In 1991, the Treatment Plant was removed from the City's Sewer
Master Plan because the service area was annexed into the Encina Wastewater Authority Service
Area.
The site of the Treatment Plant sits in a valley and is only accessible from Tamarack Avenue. Over
the years, the site has been utilized by different City Departments for storage and training. However,
at this time only a small portion of the site is being utilized for utilities operations. The Wastewater
Treatment Plant is not being utilized and the buildings and treatment facility have deteriorated. The
site contains four buildings, several holding tanks, and two large aeration ditches that are partially
filled with water, and are in declining condition. On September 28, 2009, City of Carlsbad staff
discovered a sewer main spill at a manhole located in the vicinity of the abandoned Calavera Hills
Wastewater Treatment Plant. Staff found a large amount of debris had been placed into the sewer
main by vandals, causing the spill. Because of the facility location, it is often the subject of vandalism.
Plans and specifications have been prepared to demolish the existing wastewater treatment
improvements and remove all buildings. A small portion of the site will continue to be utilized for
utilities operations, with the remaining site graded level and erosion control measures will be left in
place.
On May 24, 2011, the City Council adopted Resolution No. 2011-110 which approved the
plans and specifications and authorized the advertisement for bids for the Calavera Hills Wastewater
Treatment Plant Demolition Project, Project No. 5507. The Engineer's Estimate for the project was
$250,000. On August 2, 2011, the Utilities Department received six (6) sealed bids as follows:
