RECOMMENDED ACTION:
ITEM EXPLANATION:
The City's consultant engineering firm, Pountney and Associates,
Inc., is proceeding with the design of the Palomar Airport Road
West Assessment District, Project No. 3151. During the design
process, discussions with the Costa Real Municipal Water District
have concluded that a sixteen (16) inch waterline and pressure
reduction station are required to be installed as a part of the
assessment district project. These facilities will be installec
within the right-of-way of the improved Palomar Airport Road for
the benefit of the participants of the assessment district.
Discussions between district representatives and the assessment
district property owners have concluded with a cost participatior
ratio of 75% for the assessment district participants and 25% foI
Costa Real. It has been determined that this item i:
nonparticipating with respect to the City's contribution to the
assessment district.
The City's design engineers for this project were requested tc
provide the lump sum costs to design the installation of the 16.
inch waterline ($7,700) and the pressure reduction statio!
($7,500) as a part of the assessment district design process
Accordingly, staff recommends approval of an increase in thi
scope of work in the amount of $15,200 to enable incorporation o
these elements in the design process for this project.
Additionally, when assembling the project design scope of work
it was anticipated that adequate hydrology/drainage data for thl
drainage area was available for the design engineers to utilize
This data is required in order to identify inundation limits ani
culvert discharge conditions under a worst case situation. AI
investigation of the available drainage studies for this are
indicated a lack of such required data. Accordingly, the desigi
engineers were requested to provide lump sum fees for th
necessary hydrology/drainage tasks such as:
- waterway aerial photogrammetry $4,720 - computer models projecting 100-year
storm discharge and 100-year water
service elevations 8,625 - field verification and data gathering
of above tasks 1,520

Therefore, the total cost for the additional engineering service:
is $30,065. Staff recommends approval of the additional scope of
work to enable continuation of the design process for thi:
project.
FISCAL -IMPACT:
The City Council appropriated $2,100,000 in the 1986-87 C.I.P,
budget representing the City's contribution towards the desigr
and construction of the Palomar Airport Road West Assessment
District, Project No. 3151. The cost of the additiona.
recommended engineering services for this project will bt
absorbed in the ultimate final spread of assessment costs for the
entire project.
