Agreement Modification for Corporation Yard Master Plan
Recommended Action
Staff recommends that the City Council:
1. Authorize the City Manager to negotiate and execute a third modification to
Professional Services Agreement No. 9129 (CCS) with RNL Interplan, Inc., a
California -based company, in the amount of $34,314 (includes a 10%
contingency), to provide additional scope of work to complete the Corporation
Yard Master Plan. This will result in a new contract amount of $343,340.
2. Appropriate the budget increases as outlined in the Financial Impacts and
Budget Actions section of this report.
Executive Summary
In October 2009, Council approved an agreement with RNL Interplan, Inc. (RNL) in the
amount of $230,000 to update the 2002 Corporation Yard Master Plan. The update was
substantially completed in July 2010. Contract modifications in the total amount of
$79,026 were approved by Council in September 2011 and February 2012 for additional
scope of work. Upon further assessment, the adjacent City -owned property to the plan
area necessitated further studies. As a result, staff is requesting a third modification of
$34,314 for a total contract amount of $343,340 to RNL's agreement to complete the
Corporation Yard Master Plan.
Discussion
On October 13, 2009, Council approved Professional Services Agreement No. 9129
with RNL, in the amount of $230,000, to update the Corporate Yard Master Plan from
2002. The updated plan was substantially completed in July 2010.

On September 13, 2011, Council approved a first modification of $41,435 to
Professional Services Agreement No. 9129 with RNL to complete the Corporation Yard
Master Plan. The additional scope of work included:
• Revising the plan area configuration
• Finalizing a program for the new components
• Identifying and adding two additional operations on the site.
The phasing plan for implementing the site improvements was also revised. The
recycling operation area was originally included in the Corporation Yard Master Plan.
However, after further analysis, it was decided to move the recycling operation offsite.
This change provided an opportunity to revisit the use of that space in the Corporation
Yard Master Plan.
On February 14, 2012, Council approved a second modification of $37,591 to
Professional Services Agreement No. 9129 with RNL to conduct a study, focusing on
the best and most practical approach to build on the areas above the compressible fill.
The scope of work included performing additional borings to the site and analysis of
three possible approaches:
• Utilize structural slabs on piles at the buildings and vehicular circulation areas
• Remove the landfill and import engineered fill
• Amend the soil to stabilize the existing soil
Upon further assessment, it became apparent that mitigation of the compressible fill
cannot easily be limited to within the boundary of the Corporation Yards site, and future
mitigation will need to encompass the entire landfill area. Previous geotechnical studies
have been limited to just the Corporation Yards site. For that reason, staff is
recommending a third modification to Professional Services Agreement No. 9129 with
RNL to conduct additional geotechnical borings within Stewart Park where the existing
fill depth is not documented sufficiently to provide more information to the design team
concerning the extent and depth of the fill and potential for remediation.

Financial Impacts & Budget Actions
The third agreement modification to be awarded to RNL Interplan, Inc. is $34,314
(includes a 10% contingency). This will result in a new contract in the amount of
$343,340. Award of the agreement modification requires an additional appropriation of
$34,314 to account P014028.589000.
