Caltrans & Local MS4
Partnership Opportunities
for Stormwater Treatment Projects
For questions regarding either of these programs,
contact the Caltrans NPDES Coordinator for the
Caltrans District in which the project is located or
Anand Maganti, Watershed Manager
916-210-9849 or [email protected]
for projects in Caltrans Districts 1, 2, 3, 5, 6, and 7 Kenneth Johansson, Watershed Manager
916-956-8170 or [email protected]
for projects in Caltrans Districts 4, 8, 9, 10, 11, and 12 The Caltrans NPDES Permit issued by the
State Water Resources Control Board
encourages Caltrans to partner with local
municipalities and to provide funding for
regional water quality treatment facilities
in TMDL watersheds in which Caltrans
is identified as a responsible party, or in
significant trash generating areas. Caltrans
receives Waste Load Reduction Credit and/
or Trash Credit for financial contributions
to local municipalities to facilitate mutually
beneficial regulatory compliance objectives.
Cooperative Implementation Agreement (CIA)
CIAs provide capital and support funding
for planning, design, environmental studies,
right of way acquisition (easement only) and
construction of stormwater treatment facilities.
Treatment of runoff from Caltrans right of way
(ROW) is required. This program does not
have a dedicated funding source. The amount
of funds are limited and vary from year to
year. Regional Water Board approval of the
proposed project is required. Submit project
details* to the appropriate Watershed Manager.
Projects under consideration are prioritized
and funded accordingly. The encumbered
funds on the projects must be used by the
third fiscal year.
Financial Contribution Only (FCO)
FCOs provide funding for capital construction
costs (labor and materials) only of stormwater
treatment facilities. Treatment of runoff from
Caltrans ROW must be included. Basic project
details (brief project scope, location, tentative
schedule and estimate) must be submitted to
the District NPDES Coordinator by May 1 of
even years to reserve funds. Additional details
of the project* must be submitted by March 1
or earlier of odd years for Caltrans to develop
a Project Initiation Report. Projects will be
prioritized and if approved, funds are typically
available within two years. Exceptions to the
dates noted may be granted for high priority
projects. Project plans and specifications,
environmental document and permits, ROW
acquisition, contract advertisement, award, and
administration is the responsibility of the local
municipality. Regional Water Board approval
is not required unless non-Caltrans approved
BMPs are proposed.
Projects not selected remain eligible for
funding in following years.
For projects with multiple components
(e.g., flood control, etc.), only components
directly related to construction of the BMPs or
restoaration of areas disturbed by construction
of the BMPs are eligible.
Maintenance and operation costs under each
program must be solely borne by the local MS4.
CALTRANS HAS TWO FUNDING REIMBURSEMENT PROGRAMS * Information required to be submitted for project consideration:
1. Waterbody reach the project is located
in and where on the Reach Prioritization
Inventory List it lands
The list is available on the Caltrans
Stormwater Program website under “Tools”:
www.dot.ca.gov/env/stormwater
2. ASBS Pollutant categories treated
(for ASBS, TMDLs) or Trash (for Trash
Provisions)
1) Sediment/Nutrients/Mercury/Siltation/
Turbidity; 2) Metals/Toxics/Pesticides;
3) Trash; 4) Bacteria; 5) Diazinon;
6) Selenium; 7) Temperature; 8) Chloride.
Priority is given to projects that address
significant trash generating areas.
3. Phase the project is in (i.e., conceptual,
environmental studies, design), tentative
schedule and funding requested
Status of environmental documents, permits,
design. Provide project schedule and total
funding (show funds broken down by fiscal
year and phase).
4. Number of Stakeholders benefitting from
the project (list MS4s)
5. Type of BMP(s) to be built and number
of acres treated and demonstration of
hydraulic connectivity
Provide sizing and tributary drainage area
calculations and mapping for dry and wet
weather flow acres being treated for Caltrans
and each MS4 and a map of tributary drainage
areas. Caltrans can assist with this.
6. Status of Regional Water Board approval
(e.g., WQIP, WMP, EWMP or RB Staff)
7. Lead agency. Will Caltrans be working with
an individual MS4?
