3. Staff Update on Matadero Creek Oil Spill (10 min)
a. Karin North – Communications Office provided an update on City
website. Fire Department is the lead for this effort and was the first
on the scene. Background: Diesel spill due to exploding generator at
Veteran’s Affair campus entered into storm drain system. CA Fish and
Wildlife, Valley Water and Fire Department are working together for
cleanup. Webpage will be emailed to committee.
4. Staff Update on CIP Projects (10 min)
Michel Jeremias – been with CPA for 8 years as Senior Engineer overseeing storm drain group for 4 years. Oversees Rajeev Hada and Vicki Thai. Their
group handles and constructs Capital Improvement Projects within the City
(13 projects approved by Stormwater Ballot Measures) in the process of
designing three new projects.
a. Update on current rehab projects:
i. Rehab and replacement project – list of locations throughout
the city of pipes that need replacement. Focus is to continue to
maintain the pipes currently in the ground, not to increase
capacity. Goal is to make sure the pipes are continuing to
function.
ii. Pipes were identified through Public Services group when
cleaning and maintaining debris. Staff verified the integrity of
the pipes at this time. 60 pipes were identified by different tiers
and locations. A lot of the pipes are overlapping so the goal is
to target each of the 60 pipes to be replaced or lined this year.
Hopefully a contract will be awarded before next rainy season.
iii. Image of pipe shown during meeting – roots broken through
the pipes, Public Services group removed debris and cleaned
the pipes. Trimming device installed further upstream that cuts
any roots and branches. A camera goes in during cleanup so
staff can see the quality of the pipes. Installed 1940-1980s.
Rust affecting integrity of the pipes. Concrete pipes also have
cracks.
iv. Staff identified a couple locations with pipes that are so severe
that need replacement. Staff will check if any projects align in
the area. West Charleston Arastradero Project (cost savings –
DRAF
T
5 June 3, 2021
Streets group is funding the street re-pavement and
Stormwater group will fund the replacement of the pipe they
were already going to work on).
v. Improvement options – when a pipe is failing, a trenchless
method is used where a fabric reinforcement material is
inserted into a pipe with a material that adheres to the pipe.
The soft material is placed into a broken pipe and expands to
take the same shape as some of the pipes. This method is great
for elliptical pipes. Converting from concrete pipes to HDP pipe. Faster than full replacement. Full replacement would need
trench excavation (another option if rehab doesn’t work).
vi. Rusted pipes can be rehabbed if there are no cracks or root
intrusion. The liner will extend the life of the pipe (at least 20-
30 years depending on the quality of the pipe), the liner will
increase the velocity of the pipe.
5. Staff Update on Caltrans Trash Control Device (10 min)
Pamela Boyle Rodriguez – Stormwater Compliance Manager with
Watershed Protection Group. Work responsibilities include making sure
the City is compliant with the Regional Stormwater Quality requirements,
including business and construction inspections, reducing trash, and
trying to increase the amount of GSI at the City. Originally from the East
Coast, but lived in the West Coast for the last 20 years. Received her
undergraduate degree from North Carolina State in Natural Resource
Management and Master’s Degree in Environmental Science. Career has
been focused in Watershed/Stormwater and has been with the City for ~5
years.
a. Staff wanted to take advantage of a grant opportunity with Caltrans
to form a project on Embarcadero Road but they did not offer
enough funding at first, so staff delayed project due to tight budget.
Caltrans is now Caltrans providing full funding, but the project must
be done during this fiscal year.
b. Background – must follow strict requirements by Regional Water
Quality Control Board, every permittee in the region must reduce
trash by 100% by 2025 (extended from 2022). Reduction
percentage will be compared to 2014 levels of trash as baseline, or
no adverse impact to receiving waters (San Francisco Bay).
Currently City is at 80% trash reduction. Going from 80% to 100%
DRAF
T
6 June 3, 2021
will be a large effort. This project will provide a trash reduction
credit and get the City from 80% to 85% due to the drainage area
that will be captured. Trash capture device must catch trash as
small as 5mm.
c. Estimate for design and installation, 2 devices will be installed for
$613k. Caltrans will fund the entire project and City will take lead.
Budget includes replacing the grass and restoring the area to as it
was before.
d. Location – underground in line with the pipes by the Palo Alto Golf Course. The City’s drainage area is 189 acres, and the Caltrans
right of the way is 21 acres, the project will drain into our storm
drain system. Everything upstream will be captured in this device.
Caltrans can receive credit for reducing trash for those 21 acres.
e. Maintenance over 50 years (lifecycle of this device). Approximately
$272k to maintain from City and Caltrans will reimburse. This is
covered by the fee for maintenance of the storm drain system.
f. Staff will go to Council June 14th to enter an agreement with
Caltrans. Agreement will need to be signed by Caltrans and this will
need to be done by the end of June. We can release RFP in a couple
of months. We will be contracting consulting firm to figure out best
device to install. These devices are only made by a couple vendors.
Designs should not take too long, construction by next summer and
completed before next season in 2022.
g. Dena Mossar, question: Will there be an annual analysis of
effectiveness overtime? Will we ever know how we’re doing?
i. Pam Boyle Rodriguez, answer: We will be able to weigh the
amount of trash and sediment over time and we can look at
numbers yearly.
h. Hal Mickelson, question: How well do we do in comparison to other
cities?
i. Pam Boyle Rodriguez, answer: In Santa Clara County, there
are some cities that are further ahead and some that are
further behind. You get 100% credit with these projects, but
others such as cleanups are only partial credits. San Jose has
put in 8 of these devices and were able to receive a lot of
DRAF
T
7 June 3, 2021
credit this way. But other cities that don’t have the
topographic area to install these devices need to do other
things to reduce trash.
i. Marilyn Keller, comment: overflowing trashcans in local parks seem
like its causing litter in the area.
i. Karin North: Parks department increased trash pickups over
the weekends, but we will reach out to those departments to
increase pickups.
j. Dena Mossar, comment: There are trash pickups with automatic arms that also cause trash in the street.
i. Karin North: Zero Waste is aware of this issue and is
promoting bagging of the trash to prevent stray trash from
flying.
ii. Pam Boyle Rodriguez: Staff can share a presentation on how
we reduce trash and how we can receive credits for reducing
trash in the future.
6. Review Final Workplan (13 min)
a. Loretta Olmos – Public Works Engineering Management Analyst,
helps Michel Jeremias and Jamie Perez on Capital Improvement
Program Projects.
b. Hal Mickelson – highlighted updates made to workplan since last
meeting and what was added in response to past inputs from
committee members.
c. Karin North – Workplan was submitted and will be approved by
Council by the end of June, deadline was May. Workplan kept broad
and highlighted goals and missions. This is the first workplan of the
SWMOC.
d. Hal Mickelson - Council uses these workplans as a management
tool.

7. Staff Update on EPA Grant (10 min)
Pamela Boyle Rodriguez – Greening Parking Facilities for a Sustainable
Community
a. Staff processed documentation to receive a grant from EPA.
Submitted application May 2020. Staff did not receive the grant at
the time but was placed on a waiting list if more funding came
later. EPA reached out earlier this year to let staff know more
funding became available and staff received the grant.
b. Grant submitted by Palo Alto (lead applicant), the City of Santa Clara, and San Francisco Estuary Institute (lead researcher for
looking at water quality in SF Bay), Grassroots Ecology, and San
Jose Conservation Corps, Stormwater Clean Water Program for
Santa Clara Valley.
i. Goals of the project:
1. Retrofit two parking lots with green infrastructure in
both the cities of Santa Clara and Palo Alto.
2. Create a guidebook for other cities that include the
lessons learned from this project and how to do a
similar project for their parking lots.
3. How to provide maintenance and training for GSI, look
at what is the best framework for City Palo Alto to
create a workforce program for creating green jobs for
local community and increase local experience in GSI.
4. Community engagement and community education
ii. Project will monitor water quality entering the green
infrastructure features and exiting it, before and after
construction.
iii. Staff would like to involve the community in some way
through education event. City of Santa Clara will be doing
school education programs.
DRAF
T
9 June 3, 2021
iv. Budget for parking lot (we need to match by 50% with
partners, 1.2 mil budget). Construction will be in a couple
years 2023.
c. Lot A Emerson/Lytton; Staff looked at multiple parking lots with
grading/drainage and proximity to storm drain systems:
i. This location was chosen because troubling location to
Watershed Protection Group - over 10 restaurants use trash
bins here and spills in this location.
ii. Office of transportation would like to revamp this area. Trees need to be retrofitted. No amenities for bicycles, pedestrian
friendly
d. Ideas – proposed retrofit (preliminary)
i. GSI integration
ii. EV chargers, EV lighting
iii. Updates for community parking lot (like a Farmer’s Market)
iv. Water quality – main purpose
v. Sustainable parking lot
vi. Take concrete out and add landscaping, pervious pavement,
and integrate more trees.
e. Expensive project, Staff is not recommending making every parking
lot like this, but this project was awarded a grant.
f. Marilyn Keller, question: Trees slow down peak flows, filters the air,
and makes nicer community space. Is there also any consideration
for solar panels?
i. Pam Boyle Rodriguez, response: talked to Utility Department
and that was another idea came up. Solar panels could be
funded with the EPA grant if it fits in the budget.

person meetings.
c. Karin North – Confirm with Michel Jeremias of potential field visit for
next August meeting.
a. Michel Jeremias – Project has not gone out to bid yet and not
sure when contract will start. Group can schedule a field visit to
see rehab work that happens. Realistically, Sept/Oct timeframe
is more ideal to see something worth watching after project
starts moving along.

Green Stormwater Infrastructure
•GSI is engineered
infrastructure that is based
on natural processes to
manage stormwater
runoff
•GSI is an alternative to
“gray” infrastructure,
providing a pathway for
stormwater to:
•infiltrate,
•reduce and/or treat
pollutants, and
•provide water use
opportunities

Facility Selection Considerations
•Preferred GSI Measure Type
•Drainage Area Considerations (grade, direction of flow, size, etc.)
•Infiltration Feasibility (including underlying contamination, SLR)
•Site Type (Roadway, Park, Parking Lot, etc.)
•Space Constraints/ Site Use Constraints
•Pavement surface needs
•Proximity to buildings/foundations
•Available space to site GSI
•Utility conflicts
•Integration of GSI into Site Features
Potential to incorporate some of these into City‐wide Feasibility Maps

Permit Overview
•Tentative Order (2nd draft) very similar to Administrative
Draft (1st draft) with minor revisions
•Cumulative impact of many new/enhanced requirements has
significant resource implications:
o GSI numeric targets
o Impervious surface thresholds
o Road requirements
o New monitoring requirements
o Trash
o PCBs
o Cost reporting
o Asset management
o Additions to "core" requirements
•Required stormwater treatment
o 5,000 SF for most projects; 10,000 SF for residential
o 5,000 SF (contiguous) road projects and some pavement maintenance
•Long-term GSI numeric goal to be developed during MRP 3.0
•Short-term goal –3 acres treated per 50,000 population (prorated)
o Palo Alto: 3.92 (65,364 population)
o Projects constructed/funded between 1/1/21 and 6/30/27 count
o Can be met on a countywide basis
o Projects can be used to meet PCB requirements if in older industrial areas
New/Redevelopment
(impervious surface impacts)
•Enforceable trash load reductions
o 90% reduction by June 30, 2023
o 100% reduction by June 30, 2025
o Includes addressing trash on private properties
•Source Control Credits
o No credit for existing source control actions, only new actions
o Credits only allowed towards 90% target, not 100%
Trash Reduction
•Source Property ID & Abatement
o Acreage to be treated 913 acres
•Control Measure Implementation in Old Industrial Areas
o Acreage to be treated 664 acres or load reduction of 121 gm/yr. of PCBs
o GSI counts toward reduction target
PCBs & Mercury Reduction
•Bacteria Controls
o Applies to Mtn. View and Sunnyvale (for now)
•Discharges associated with unsheltered populations
•NEW:
•Cost tracking
•Asset Management
