PUMP SITE. NO.1
PRO
1. It is at the northerly end of Macario Park (instead of
being wi thin the park) and is secluded from planned
homes.
2. The ground surface elevation at this site is between 15
feet to 20 feet which will provide a IIgood" pump station
depth.

1. This site requires an easement from SDG&E.
2. The access road to the pump station site is quite long
if access will be via the force main alignment.
3. It is closer to the lagoon than any of the other sites.
PUMP STATION SITE NO.2
PRO
1. It is further from the lagoon that Pump Station Site No.

2. It provides a larger area for pump station construction
than does Pump Station Site No.1.

5 •
The site does not contain any riparian habitat, salt
marsh, or similar environmentally sensitive features.
This site requires a shorter sewage PM than does Pump
Station No.3.
It is within City property and does not therefore,
require acquisition of any easements.

CON
1. The site is approximately 10 feet higher in ground
elevation that Pump Station Site No. 1 and 15 feet
higher than Pump Station Site No.3. The pump station
will therefore need to be deeper than for Pump Station
Sites No.1 or No.3.
2. It is located within the future Macario Park.
3. I t requires a longer force main length than for Pump
Station Site No.1 •
PUMP STATION SITE NO.3
PRO
1.
2.
It is further from the lagoon than Pump Station Site No.
1.
It provides a larger area for pump station construction
than either Pump Station Site No.1 or No.2.
3. It has a ground elevation of approximately 10.0 feet,
which minimizes pump station depth.

It's easterly location ml.nl.ml.zes the length of 30"
gravity sewer that is required within Cannon Road.
There will be easy access to the pump station site from
Cannon Road.
The site may contain low quality riparian habitat.
It's easterly location maximizes the force main length.
It will be adjacent to future homes and businesses.
PUMP STATION SITES NO. 4 AND 5
PRO
1. The sewage force main length is shorter than for Pump
Station Site No.3.
2. These sites are not adjacent to future homes.
CON
1. The sites are within, or adjacent to, sensitive salt
marsh or riparian habitat.

2. Extensive grading may be required to create an adequate
pad for the pump station site.
3. These sites are at the northerly end of Macario Park,
but are closer to planned homes or businesses than Pump
Station Site No.1.
4. These sites are close to the alignment of future Macario
Bridge which may detract from effective site utilization
and access.
5. They are adjacent or close to future businesses.
