RECOMMENDED ACTION:
Adopt Resolution No. 2011-110 approving plans and specifications and authorizing the City
Clerk to advertise for bids 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 and 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 the site 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, 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 improvements and remove all
building materials. The site will be graded level and erosion control measures will be left in place.
ENVIRONMENTAL IMPACT:
The project is exempt from the California Environmental Quality Act (CEQA) per CEQA Guidelines
Section 15268 - Ministerial projects. The Notice of Exemption was filed with the County Clerks Office
for a 30-day public review period (January 14, 2011 - February 16, 2011).

The current appropriation in the amount of $723,500 also included work to realign the existing
trunk sewer pipeline crossing the treatment plant property. The sewer pipeline relocation work
was completed in the fall 2009 during the emergency repair, under the project Tamarack Sewer
Replacement, Project No. 5510. In addition, all engineering and preparation of the plans and
specifications were completed by staff. Based on the engineer's estimate, sufficient funds have
already been appropriated for this project.
