By motion,
1. Approve the Plans and Specifications for the El Camino Real at Don Juan
Avenue Retaining Wall Project (CIP 07111 ); and,
2. Authorize staff to solicit and receive bids.
EXECUTIVE SUMMARY:
Plans and Specifications for the El Camino Real at Don Juan Avenue Retaining Wall
Project have been prepared. A copy of the plans and specifications is available for
review in the City Clerk's office. A copy has also been placed in the City Council office.
Staff recommends approval of the plans and specifications and authorization to solicit

DISCUSSION/ANALYSIS:
On September 18, 2012, the City Council approved a Personal Services Agreement
with Huitt-Zollars, Inc., to prepare plans and specifications for the El Camino Real at
Don Juan Retaining Wall Project in the amount of $48,425. This slope repair project
entails the design and construction of a retaining wall along the westerly slope area of
El Camino Real at the Don Juan Avenue intersection adjacent to the Capistrano Unified
School District (CUSD) property located at 31422 Camino Capistrano to prevent
potential road failure/collapse resulting from severe slope erosion that has taken place

over the years. The gravity wall was selected from three other wall options for
construction at this location as it offered the lowest implementation cost, less site and
neighborhood impacts during construction, shorter construction duration, minimum
maintenance (up-keep), and is consistent with the City's Architectural Design
Guidelines. Fifteen (15) existing Pepper trees located along the westerly slope area of
El Camino Real will be removed as part of the project to alleviate public safety
concerns. These Pepper trees were determined by West Coast Arborist to be in poor
health and vigor, diseased, structurally unsound and unstable. In consideration of the
aesthetic impacts to the neighborhood, a landscape component was subsequently
added to the project's scope of work during the latter part of design when it was clear
that the majority of existing Pepper trees located along the westerly eroded slope area
of El Camino Real could not be saved. The parkway landscape design was developed
through close collaboration between staff and a neighborhood representative who is
also a licensed professional landscape architect. A new parkway space on the westerly
side of El Camino Real of between 8.5' to 11.5' within the existing slope area will be
created to implement the proposed landscape scheme.
FISCAL IMPACT:
The Capital Improvement Program (CIP) budget for Fiscal Year 2013-2014 (available as
of July 1, 2013) includes $405,000 for the construction of CIP 07111, and is sufficient to
cover the construction cost estimated at approximately $373,405.
ENVIRONMENTAL IMPACT:
The City's Environmental Administrator has reviewed the project and has determined
that the project qualifies for a Class 1 (c) Exemption per Section 15301 of the California
Environmental Quality Act (CEQA) Guidelines. The proposed project includes
provisions for archeological monitoring during demolition and grading which will assure
that project impacts would not occur and thus, allow approval of the Notice of
Exemption.
PRIOR CITY COUNCIL REVIEW:
• On September 18, 2012, City Council approved a Personal Services Agreement with
Huitt-Zollars, Inc., to prepare Plans, Specifications, and Cost Estimate (PS&E) for
the El Camino Real at Don Juan Avenue Retaining Wall Project (CIP 07111) and the
Paseo Peregrina Cul-De-Sac Drainage Mitigation Due to Soil Subsidence Project
(CIP 12501) for a total amount of $65,295 ($48,425 for CIP 07111 and $16,870 for
CIP 12501).

COMMISSION/COMMITTEE/BOARD REVIEW AND RECOMMENDATIONS:
• On March 21, 2013, the Design Review Committee (DRC) conducted a Work-
session to review the project details. The Committee provided comments and
requested that additional landscape information and a material wall sample be
presented to the Committee for consideration.
• On May 28, 2013, staff presented the project to the Cultural Heritage Commission
(CHC). The Commission provided comments regarding preference for a stone wall,
or a wall type and color similar to the existing WPA wall, as opposed to the proposed
gravity wall, as represented by the wall sample made available for viewing during the
meeting.
• On June 6, 2013, staff presented additional landscape information and a material
wall sample as previously requested to the DRC for consideration. DRC forwarded
the wall and landscaping concept, inclusive of the wall sample, to the Planning
Commission with a recommendation of approval.
• On June 25, 2013, staff presented the project to the Planning Commission. The
Commission forwarded the project to the City Council with a recommendation of
approval, and with comments to consider timing of construction in conjunction with
