N" Council Memorandum
November 6, 2014
TO: City Council
FROM: Robert A. Hill, Natural Resources Manager
Michael Codron, Assistant City Manager
VIA: Katie Lichtig, City Manager
SUBJECT: Laguna Lake Dredging and Sediment Management Project
At the October 21" City Council meeting, following public testimony for items not on the
agenda, the Council requested that staff prepare a memorandum that details the process and
timeline for implementing a prospective dredging project for Laguna Lake.
At the present time, staff has prepared a draft Capital Improvement Plan ( "CIP ") project
proposal, known as the "Laguna Lake Dredging and Sediment Management" project, which will
be reviewed and ranked by the CIP Committee in the coming weeks. Ultimately, the Council will
have the opportunity to determine if this project should be prioritized as part of the 2015 -17
Financial Plan process. The CIP project is intended to provide one of the key implementation
steps contemplated by the City Council adopted Laguna Lake Natural Reserve Conservation
Plan ( "LLNRCP ") and the timing of its implementation is subject to available funding, which is
anticipated in the LLNRCP to include a variety of sources, including a property based
assessment.
If prioritized in the Financial Plan, the project would proceed in two distinct phases. The first
phase of the project includes development of all of the information necessary to obtain the
necessary funding and permits for what is anticipated to be a long term and expensive project. At
minimum, this work includes:
1. Preparation of updated studies (soil / sediment samples; biological, noise, and traffic /
emissions) to include with permit applications to resource agencies, including our own
environmental review process.
2. Engineering and project specifications (suitable for permitting and contractor's bid
packages pursuant to issuance of a formal Request for Proposals).
3. Sediment disposal site land tenure (disposal could be accomplished partially on -site; plus
an off -site local location may be needed, with license agreement, easement, or purchase).
4. Regulatory agency permit applications (CA Department of Fish and Wildlife, Streambed
Alteration Agreement; Regional Water Quality Control Board, Section 401 Water
Quality Certification; US Army Corps of Engineers, Section 404 Dredged Materials
[note: up to 135 day review period allowed by law following issuance of Army Corps
permit]; NOAA Fisheries Biological Opinion Consultation, and possible US Fish and
Wildlife Service and Tribal consultations).
5. Updated project - specific environmental document (City Council previously adopted a
Mitigated Negative Declaration pursuant to the California Environmental Quality Act for
na Lake Dredging and Sediment Management Project
e2
a dredging project in 2009; however, an updated environmental document would be
required that is adopted within 1 year of project initiation). This work will be prepared by
a consultant and review would be overseen by the Community Development Department.
6. Consideration of funding sources is also a key preliminary consideration for the project.
A detailed evaluation, feasibility tests, community outreach, and potential initiation of a
Community Facilities District or similar financing mechanism will be required, as was
discussed in the LLNRCP at the Fiscal Statement section (p. 34) and Appendix F
Conceptual Framework for Cost Allocation.
We anticipate that the first phase of work will require as much as 18 months to complete. Once
the components of the first phase are in hand, the second phase can begin with the physical
dredging project. The exact strategy for the dredging project (e.g. timing / duration, equipment,
costs, impact avoidance and mitigation) will be better understood following the first phase of
work.
Preliminary conversations with contractors and others that have embarked upon lake excavation
or dredging projects indicate that ideal lake conditions are either completely dry for excavation,
or as full as possible for a dredging project. An excavation project is the least expensive option,
while a dredging project appears to be the environmentally superior option as it entails less noise,
dust, and heavy equipment emissions. Staff will attempt to leave both options open, from both a
job specification and permitting standpoint, so that we can potentially begin work under either
condition, unless otherwise directed by City Council.
In the meantime, as the Laguna Lake dredging project was previously included in the City's
long -term CIP, the City Council and community will next have the opportunity to discuss the
potential for this project at the November 13th "Setting the Stage" Special Workshop where the
status of General Plan goals, Major City Goals, and both long -term and current CIP projects will
be discussed.
As always, please feel free to be in touch with Natural Resources Manager Robert Hill at (805)
781 -7211 or rhillgslocity.org.
