CHULA VISTA CITY COUNCIL MEETING OF: May 15, 1 973
ITEM TITLE: Resolution - Approval of Change in Contract in Excess of $1000,
Construction of Parking Lots and Park Facilities at Halecrest
and Hilltop-Telegraph Canyon Parks
INITIATED BY: Director of Public Works/City Engineer
BACKGROUND
The grading of Hilltop-Telegraph Canyon Park site was accomplished during
the heavy rains of February and March, 1973. The park is situated along
the Telegraph Canyon drainage basin. Runoff from these storms caused
considerable erosion of the dirt drainage channel at the easterly edge of
the park.. Such erosion exposed approximately 33 feet of 12" concrete
coated steel watermain and 30 feet of 4" high pressure gas main. These
utilities are located within easements running north and south through
the park site.. The utility companies are lowering their facilities to
protect them from possible future damage.
To prevent further erosion, the concrete channel swale has been redesigned
to transition from a 6 foot width at a point 50 feet west of the utility
lines to an 18 foot width at the major drainage structure near Hilltop
Drive. In addition, grouted rip-rap has been added to act as an energy
dissipater to slow the velocity of the water as it leaves the culvert
pipes under Hilltop Drive.
It was discovered after Pacific Engineers commenced work on the in-
stallation of sidewalks and other improvements at the park sites that
certain deficiencies existed in the grading of the parking lots, performe
by McGahey Construction, the grading contractor.
Rather than have to bear the cost of moving into the site again and
correcting the grading deficiencies, McGahey Construction, by letter
(continued on supplemental sheet)
