TITLE : APPROVAL OF PLANS AND
SPECIFICATIONS AND AUTHORIZATION TO BID LEO
CARRILLO RANCH HISTORIC PARK EROSION
REPAIRS AND DRAINAGE IMPROVEMENTS
RECOMMENDED ACTION :
Adopt Resolution No. 2005-374 , approving the plans and specifications, and authorizing the
advertisement of bids for Erosion Repairs and Site Drainage Improvements at Leo Carrillo Ranch Historic
Park, City Project Number 4501 1.
ITEM EXPLANATION :
In August 2003 Leo Carrillo Ranch Historic Park was opened to the public after completing the park's
restoration, which included a variety of improvements and amenities. During the construction of the park,
there were two types of decomposed granite (d.g.) paving installed at the park, stabilized and non-
stabilized. Stabilized d.g. consists of the regular material mixed with a binder creating a more stable and
less erosive surface for walks, trails and parking areas. Due to budgetary issues for the Phase II
construction, stabilized d.g. was used in only the most critical areas (steeper areas and more highly used
areas such as the large visitor parking lot).
In 2004 and again during the storm events of 2005, staff recognized a problem at the Ranch related to the
continual erosion of non stabilized d.g. surfacing. As can be seen in the attached photos, (Exhibit 2) any
significant rain causes the non stabilized d.g. to erode and to wash into the storm drains. The erosion also
creates public safety hazards resulting in roping off areas of the park for public access and requires the
Public Works Department to buy and install new d.g. to fill in the ruts each time a significant storm event
occurs .
Areas where stabilized d.g. has been installed, seem to be holding up much better during storm events and
with the visitor wear and tear associated with normal park use.
Proiect Description
To address the continual erosion problems, staff and GVP Consultants, a local Civil Engineering firm,
prepared a design for a more permanent solution to this problem.
The proposed erosion repairs and improvements will include the following:
- - - -
-
Supplemental stabilized d.g. to re-establish grades for positive drainage
Minor grading to redirect water to minimize erosion
An additional catch basin to collect run-off
Installation of a cobble swale to direct water away from the existing historic buildings
Applications of stabilizer solutions to stabilize previously installed non stabilized d.g. areas
The project plans and specifications are available for review at the Recreation Department.
If Council approves authorization for the bidding for the project, it is estimated that work for the erosion
repairs and improvements would begin in April. The work will require approximately one (1) month for
completion.
