El Camino Real Bluff Emergency Repair at Tamarack Avenue {District 2)
This memorandum provides an update to a previous memorandum dated Oct. 22, 2020
(Attachment A), on the El Camino Real Bluff Emergency Repair at Tamarack Avenue (Project).
Background
Attachment A, which is a Council Memorandum dated Oct. 22, 2020, provides background
information on the Project.
Discussion
On Oct. 29, 2018, the city received a Section 404 of the Clean Water Act permit (404 Permit)
from the U.S. Army Corps of Engineers (USACE). Since then, the city has been actively
maintaining the Project area by removing invasive species, hydroseeding and conducting
environmental monitoring. To satisfy the 404 permit requirements, hydroseeding was initially
placed within the Project footprint on Aug. 19, 2019.
In accordance with the 404 Permit, maintenance and monitoring of the site are required for
two years after placement of the hydroseeding, provided that no more than 10% of the Project
be vegetated with non-native or invasive species. Staff submitted a revised version of the Year 1
annual report to the USACE on June 11, 2021. This annual report documented the results for
the first year of revegetation area maintenance and monitoring (Aug. 17, 2019 through
Aug. 16, 2020). Staff anticipate completing this maintenance and monitoring by Aug. 19, 2021.
In addition to these monitoring and maintenance efforts, staff are also in the process of hiring a
consultant to assist the city with the Drainage Project BFB-U. The Drainage Project BFB-U
involves restoration and enhancement of a sparsely vegetated tributary that originates 1,500
feet south of Chestnut Avenue and extends for approximately 3,000 feet along the east side of
El Camino Real. Water flow through this tributary causes minor to severe erosion around its
perimeter, which includes the El Camino Real road embankment near the intersection with
Tamarack Avenue. The proposed enhancements will help reduce erosive velocities within the
conveyance channel and aid in the reduction of sediment transport towards the Agua Hedionda
Creek.

On Jan. 11, 2021, staff posted a request for qualifications (RFQ) on PlanetBids to advertise for
engineering and environmental services to support the design and environmental assessment
of the Drainage Project BFB-U. On Feb. 25, 2021, staff received four proposals from consultants.
A selection panel comprised of city staff evaluated and ranked the proposals based on best-
value criteria. Staff are currently negotiating the final scope of services and fees with the
selected consultant, in keeping with Carlsbad Municipal Code Section 3.28.060. In August 2021,
staff will request City Council authorization to execute a professional services agreement with
the selected consultant.
Next Steps
Staff will continue to maintain and monitor the area associated with the emergency repair
Project, in accordance with the requirements stipulated within the 404 Permit until the
anticipated completion date of Aug. 19, 2021.
In August 2021, staff will request City Council authorization to execute a professional services
agreement with the selected consultant for the Drainage Project BFB-U.

Re: El Camino Real Bluff Emergency Repair at Tamarack Avenue Update
This memorandum provides an update to a previous memorandum to City Council on the
El Camino Real Bluff Emergency Repair at Tamarack Avenue (Project) dated May 2, 2019
(Attachment A).
Background
On June 8, 2018, the San Diego Regional Water Quality Control Boar.d (San Diego Water Board)
issued a Notice of Violation (NOV)/lnvestigative Order (10) for the Project. On April 23, 2019,
staff submitted th·e proposal to the San Diego Water Board to satisfy the requirements for
compensatory mitigation and to offset the impacts to non-wetland waters of the United States
and/or the State of California associated with the Project.
The proposed mitigation plan applied mitigation credits that the city held with the North
County Habitat Bank. Staff has also worked with the U.S. Army Corps of Engineers (USACE) to
fulfill the permit requirements defined within Section 404 of the Clean Water Act (404 Permit)
for the Project.
Discussion
On May 28, 2019, staff provided the certification of mitigation credit from the North County
Habitat Bank to the San Diego Water Board (Attachment B). On July 19, 2019, the San Diego
Water Board approved the city's proposed mitigation plan and accepted the certification of
mitigation credits (Attachment C).
Since receiving the 404 Permit from the USACE on Oct.·29, 2018, the city has been actively
maintaining the Project area by removing invasive species, hydroseeding and conducting
environmental monitoring. To satisfy the 404 Permit requirements, hydroseeding placement
was completed within the Project footprint on Aug. 19, 2019. In accordance with the.404
Permit, maintenance and monitoring of the site are required for two years after placement of
the hydroseeding, provided that no more than 10% of the Project be vegetated with non-native
or invasive species. Staff anticipates completing this maintenance arid monitoring by
Aug. 19, 2021.

In addition to these monitoring and maintenance efforts, staff is currently preparing a Request
for Qualifications (RFQ} for engineering and environmental services to support the design of
Drainage Project BFB-U. Funding for the project was identified in the 2008 Carlsbad Drainage
Master Plan as coming from the Planned Local Drainage Area fee program. The project involves
restoration and enhancement of a sparsely vegetated tributary that originates 1,500 feet south
of Chestnut Avenue and extends for approximately 3,000 feet along the east side of El Camino
Real. Water flow through this tributary causes minor to severe erosion around its perimeter,
which includes the El Camino Real road embankment near the intersection of Tamarack
Avenue. The proposed enhancements will help reduce erosive velocities within the conveyance
channel and aid in the reduction of sediment transport towards the Agua Hedionda Creek.
Next Steps
Staff will continue to maintain and monitor the area associated with the· Project, in accordance
with the requirements stipulated in the 404 Permit, until an anticipated completion date of
Aug. 19, 2021.
Staff will also prepare an RFQ for engineering and environmental services to support the design
of Drainage Project BFB-U, which is expected to be released in mid-2021.
