2.0 PROJECT INFORMATION

2.1 City Description

The City of La Cañada Flintridge (City) is approximately 8.5 square miles in area and is bordered by the Angeles National Forest on the north, and the cities of Pasadena and Glendale on the east

and south, and the unincorporated portion of the County of Los Angeles on the west. The City is

13 miles northeast of the City of Los Angeles. The City was incorporated in 1976 and home to the Jet Propulsion Laboratory, the Descanso Gardens, and the Lanterman House.

The City has a population of 20,550 and is primarily a bedroom community comprising largely of

owner-occupied single-family homes. The Foothill Boulevard Downtown Village offers a variety of small shops, restaurants, and services. Residents also have access to parks; a community center;

a YMCA; a multiplex movie theater; public and private libraries; golf tennis and riding clubs; and

scenic hiking and equestrian trails.

2.2 Project Description

PROJECT LOCATION: The project is located within the boundaries of the City of La Cañada

Flintridge (City). The Flint Canyon Trail is a 2.4 mile-long trail running through the Flintridge area of the City, connecting Hahamongna Watershed Park (formerly Oak Grove Park) located in the City

of Pasadena on the east.

PROJECT LIMITS: The limits of the project are along a portion of the Flint Canyon Trail and the

adjacent streambed within Flint Canyon beginning at a point near the trail entrance at Oak Grove Drive and extending approximately 2000 feet in the upstream direction. (Attachment 1). The

Consultant shall give priority to the most eroded section of the slope, which is the middle 1000-foot section. The City has recently produced a video of the channel within the limits of the project.

A link will be provided with the RFP on the City website for review by the Consultant.

PROJECT PURPOSE: The purpose of this project is to inhibit stream flows from eroding and

undercutting the slope supporting the Flint Canyon Trail. The project will additionally improve the general condition of the trail over the adjoining 1000 feet.

PROJECT BACKGROUND: The Flint Canyon Trail has undergone serious erosion on its downslope

which could be caused by severe rainstorms and runoff from the Flint Wash located below the trail.

In 2009, the City completed extensive repairs with grant funds to the upslope of the Flint Canyon Trail which has also experienced significant erosion. Although the upslope was repaired, the

downslope has continued to erode over time. The City recently conducted repairs to some areas

mailto:[email protected]



of the downslope; however, a long-term solution must be implemented. Otherwise, the ongoing erosion will compromise the entire slope and the extensive upslope repairs completed by the City

(Refer to the report in Attachment 2).

PROJECT FUNDING: The overall budget for the preparation of an environmental document,

environmental permitting, and design plans is $300,000 from a Proposition 68 Santa Monica Mountains Conservancy Grant (Grant). A copy of the grant application is included in Attachment 3.

PROJECT SCHEDULE: In order to comply with the Grant requirements, the Consultant must

complete the Project by December 31, 2020.

consider proposals from participants in such collusion. No person, firm, or corporation under the same or different name, shall make, file, or be interested in more than one proposal for the same

work unless alternate proposals are called for. A person, firm, or corporation who has submitted

a sub-Proposal to a Consultant, or who has quoted prices on materials to a Consultant, is not thereby disqualified from submitting a sub-Proposal or quoting prices to other consultants.

Reasonable ground for believing that any Consultant is interested in more than one proposal for the same work will cause the rejection of all proposals for the work in which a Consultant is

interested. If there is reason to believe that collusion exists among the consultants, the City may refuse to consider proposals from participants in such collusion. Consultants shall submit as part

of their proposal documents the completed Non-Collusion Affidavit provided herein.

19.0 INDEPENDENT CONSULTANT

The Consultant covenants that it presently has no interest, and shall not acquire any interest, direct

or indirect, financial or otherwise, which would conflict in any manner or degree with the

performance of the services hereunder. The Consultant further covenants that, in the performance of this contract, no subconsultant or person having such an interest shall be employed. The

Consultant certifies that to the best of his knowledge, no one who has or will have any financial


interest under this contract is an officer or employee of City. It is expressly agreed by the Consultant that in the performance of the services required under this contract, the Consultant,

and any of its subconsultants or employees, shall at times be considered independent consultants and not agents of the City.

20.0 COMPLIANCE WITH LAWS

All proposals shall comply with current Federal, State, and other laws relative thereto.

21.0 WITHDRAWAL OF PROPOSAL

A Consultant may withdraw its proposal, without prejudice prior to the time specified for the

proposal opening, by submitting a written request to the City to withdraw, in which event the proposal will be returned to the Consultant unopened. No proposal received after the time specified

or at any place other than that stated in the RFP will be considered.

22.0 LABOR LAWS

The successful Consultant and its agents, employees, and subconsultants shall comply with all

applicable provisions of the Labor Code and all Federal, State, and Local laws and regulations pertaining to hours of work; employee wages and other compensation; non-discrimination; and

other conducts of work.

23.0 FIRM COMMITMENT OF AVAILABILITY OF SERVICE

Once a proposal is opened, the Consultant is expected to maintain an availability of service as set

forth in its proposal for a ninety (90) day period after the due date for receipt of proposals and that the proposed work will be performed at the “Not to Exceed” price in the proposal.

24.0 LIMITATIONS AND RESERVATIONS

All responses to this RFP shall become the sole property of the City.

The City reserves the right to reject any or all proposals and any item or items therein, and to

waive any non-conformity of proposals with this RFP, whether of a technical or substantive nature, in the interest of the City.

25.0 RFP NOT CONTRACTUAL

This RFP does not commit the City to award a contract, or to pay any costs incurred in the preparation of the proposal.

26.0 FORMS TO BE INCLUDED

Subject: Flint Wash Review

Dear Ms. Wilson:

At the request of the City of La Cañada Flintridge (City), Northwest Hydraulic Consultants (NHC) has performed a review of conditions on Flint Wash, with emphasis on a section of the channel in the Flintridge area of the City that is experiencing erosion problems. The City has recently constructed stabilization improvements for a trail adjacent to the channel, but is concerned that ongoing erosion continues to threaten the trail and the improvements constructed to date. The City also wishes to explore potential synergy between trail stabilization and the objectives of the Arroyo Seco Ecosystem Restoration Feasibility Study, currently in the planning process by the US Army Corps of Engineers (USACE) and Los Angeles County Department of Public Works (LACDPW). The purpose of this letter report is to briefly describe Flint Wash watershed and erosion conditions at the trail, present some initial ideas on channel stabilization that could also provide ecological benefits, and evaluate the potential intersection of erosion solutions for the trail with Feasibility Study objectives.

FLINT WASH WATERSHED

General Description

Flint Wash is a tributary to the Hahamongna Basin and the Arroyo Seco. The wash drains approximately 4.5 square miles of land through the Crescenta Valley. The length of the drainage from the San Gabriel Mountains to the Hahamongna Basin is about 24,000 feet with the main axis of the watershed in a northwest‐southeast orientation. The peak elevation of the watershed is about 3,225 feet in the San Gabriel Mountains, and the lowest elevation is at the mouth of Flint Wash into the Hahamongna Basin and Devils Gate Reservoir at an elevation of about 1,040 feet. The climate is Mediterranean with mild winters and hot summers, and an average annual rainfall of approximately 22 inches. Rainfall amounts and intensities are highest in the upper portion of the watershed in the San Gabriel Mountains, and

Flint Wash Review 2 Draft Letter Report

intense storms have a high potential for production of sediment and debris loads from the mountain canyons.

Figure 1 shows a map of the watershed. The headwaters drain the south facing and mostly undeveloped slopes of the San Gabriel Mountains through steep canyons (Winery, Hay, and Gould Canyons). These tributaries cross the alluvial fan surface at the base of the mountains, where land use in this area is primarily single family residential development. The 210 Freeway passes through the center of the watershed and land uses in the vicinity of the 210 Freeway and nearby Foothill Boulevard include commercial and industrial development. In the developed areas, flows are carried by a combination of surface flow in streets, constructed channels, and underground conduits. The channels from Winery Canyon, Hay Canyon, and smaller sub‐drainages from the developed area intersect the base of the San Rafael Hills at the distal edge of the alluvial fan surface near Descanso Gardens, and the main channel of Flint Wash turns southeast at this point to follow the boundary between the alluvial fan and the San Rafael Hills. The Gould/Paradise Canyon tributary joins the main channel from the north about one mile upstream of Devil’s Gate Dam. Several small tributary channels flow to the main channel from the San Rafael Hills on the south. This area of the watershed is primarily low to moderate density residential land use and much of the tributary channel system is natural or unlined, with culverts at road crossings.

Historical Channel Morphology

The historical channels in the watershed were formed in response to geologic and climate characteristics. Infrequent but sometimes intense storm events that carry high sediment and debris loads from the mountain canyons supplied sediment that was distributed in the channel system and on the alluvial fan surfaces. Alluvial fan channels are characteristically migratory and subject to filling and avulsion during runoff events. Historically, channels near the base of the mountains were probably the least stable due to sediment production from the mountain canyons. The recent fan deposits (Holocene) are underlain by older consolidated (late Pleistocene) fan deposits. The main channel of Flint Wash is formed at the junction between the alluvial fan deposits and the granitic (diorite) rocks of the San Rafael Hills (USGS, 2005). This section of channel runs along the distal edge of the fan surface from the area near western boundary of the watershed near Descanso Gardens (channels to the west flow to Verdugo Wash) to the Arroyo Seco (Figure 2). The Arroyo Seco flows through a constriction in the granitic rocks near their junction with the older fan deposits underlying Altadena, presently the site of Devil’s Gate Dam. Devil’s Gate Dam was built in 1920 to control flooding on the Arroyo Seco.

Figure 3. Historical Topographic Mapping (USGS, 1928)

The location of the Berkshire Avenue Bridge across Flint Wash is visible in the 1928 mapping to the south of the area labeled Flintridge Country Club. Due to the scale of the mapping, detailed interpretation of channel form at the time is difficult. Immediately upstream of Devil’s Gate Dam the historical mapping shows a relatively entrenched channel between the alluvial fan deposits and the hillslope to the south. Upstream of the Berkshire Avenue crossing, the mapping shows a broader stream valley or wash morphology, which narrows again upstream of the next road crossing (presently Woodleigh Lane). The Berkshire Place crossing is the location of a granitic bedrock outcrop in the bed of the channel that provides a grade control on the stream profile upstream of the bridge (Figure 4).


Figure 4. Bedrock outcrop at Berkshire Place Bridge

Anthropogenic Changes

Hydrologic Change Due to Development

Development in the watershed dates back to the late 19th century, but the most intensive period of growth occurred from the 1930s through mid‐1960s. A review of historical mapping indicates that the alluvial fan surfaces in the watershed were nearly completely developed during that period. Construction of the 210 Freeway in the project area began in the late 1950s and the first segment (from Flintridge to Pasadena, including the bridge at Flint Wash) was completed in 1966. With the change in land use in the watershed, peak flows to Flint Wash likely increased due to increased runoff from impervious surfaces. In addition, dry weather flows may have increased due to return flows from landscape irrigation, car washing, and other urban water uses. There is no gage on Flint Wash, and therefore no historical record of flows. However, these changes are typical of other developed watersheds in the region. In addition to increased flows, hydrologic change may have occurred due to fill in floodplains and change in distributary channel patterns associated with development. As development occurs, channels are typically made more efficient and confined to a single, stabilized path. Compared to the natural alluvial fan morphology that includes many channels and distribution of flows and sediment on the fan surface, the modified stream morphology is typically more efficient and delivers higher peak flows to the lower portions of the watershed. Anecdotal accounts and NHC observations indicate that the lower portion of Flint Wash is perennial, with the exception of the area from Devil’s Gate Dam to just upstream of the 210 Freeway, where subsurface flow occurs in late summer and dry periods. In this review we were not able to obtain information on whether the channel was historically perennial or persistent surface flows are due to anthropogenic change and urban runoff. Available water quality data indicate that the stream is affected by non‐point source pollution sources in the watershed.


Channel Modifications

As development occurred in the watershed, large storm events, such as the New Year’s event of 1933, caused substantial flooding and property damage. Beginning in the 19302 or 1940s, Los Angeles County constructed channel and debris basin improvements over a period of 30 to 40 years to reduce flood risk in the watershed. Flood control facilities include debris basins at the mouth of canyons, concrete lined channels and conduits across the alluvial fan surface, and concrete lined channels and box culverts in the main stem of Flint Wash from near Descanso Gardens to near Berkshire Avenue.

210 Freeway

At the 210 Freeway crossing of Flint Wash, the channel is widened, protected with rock riprap, and nearly completely bare of vegetation. Because this crossing is skewed to the channel, the channel modifications associated with the freeway crossing extend over about 500 feet. The date of installation of the rock riprap (i.e., during or after construction of the bridge) was not determined as part of this review.

Devil’s Gate Dam

Devil’s Gate Dam was constructed in 1920 by Los Angeles County to provide flood and debris storage on the Arroyo Seco. The dam is just downstream of the confluence of Flint Wash and Arroyo Seco. A detailed investigation of potential changes in stream grades associated with the dam has not been completed as part of this review, but the dam is constructed at a natural rock outcrop and it is likely that the low level outlets in the dam are near the historical base level of Flint Wash. However, when flood storage occurs behind the dam, the lower portion of Flint Wash is inundated by backwater from the dam. Before spillway modifications were made in 1997 to meet dam safety standards, the backwater effect would extend as far up the channel as the Berkshire Place Bridge. With the spillway elevation modified to 1040.5 feet, the backwater at the spillway crest elevation extends about 1600 feet upstream of the outlet into the flood basin.


FLINT CANYON TRAIL EROSION

Erosion Problems

The 2‐mile long Flint Canyon Trail trail connects the Hahamongna Watershed Park with trails in Cherry Canyon and the City of Glendale to the west. The trail also connects to the Arroyo Seco Trail, which in turn connects northward to the Gabrielino Trail in the Angeles Forest. The section of trail that runs along the lower portion of Flint Wash between Berkshire Place and Oak Grove Drive has experienced significant erosion problems. In particular, an approximately 800 foot long section of trail that runs just south of the 210 Freeway along the north side (left bank, looking downstream) of the channel has experienced problems both from upslope erosion and undercutting and failure of the creek banks. The location of this trail section is shown in Figure 5.

In 2009, the City completed extensive repairs to stabilize the slope above the trail using a combination of grant funds, Los Angeles County Proposition ‘A’ funds, and the City General Fund. Although the upslope repair was successful, erosion problems on the creek side of the trail threaten its stability. In 2014, the City awarded a contract for repairs to the downslope side of the trail for $336,500. The repairs provide temporary stabilization of the area immediately adjacent to the trail, but it remains threatened by larger scale erosion process along the channel bank below the trail. Figures 6 and 7 show the types of repairs that have recently been made on the upslope and downslope sides of the trail.

The trail location varies from about 15 feet to 30 feet in elevation above the channel, and bank slopes vary from nearly vertical to about 2 horizontal to 1 vertical. Soil and stratigraphic conditions vary along the toe of the slope. Soils are generally silty sands and sandy silts, with occasional exposures of cemented material, presumed to be the older fan deposits mapped in Figure 2. Active erosion is evident along the toe of slope and at the contact with cemented material, and this process is undercutting vegetation and destabilizing the middle and upper slopes. If left untreated, progressive failure of the banks can be expected that will undermine the repairs constructed on the downslope side of the trail near the top of the slope. Figures 8 through 11 show typical erosion problems.

Contributing Factors

Detailed hydrologic, geomorphic, and hydraulic evaluations are beyond the scope of this review. More detailed investigation could more clearly define causal mechanisms for the erosion problems, but several factors can be identified from the history of the watershed that may contribute to the erosion problems on this section of the channel, and are generally described below:

Increased peak flows – urbanization of the watershed and channelization of the streams that

naturally flooded the alluvial fan and wash surfaces likely increased the magnitude of peak

flows.

Sediment reduction – installation of debris basins and urbanization of the watershed likely

reduced sediment inflows to the wash. As sediment loads are decreased, channel degradation

and erosion may occur as relatively clear water flows entrain sediment in the unprotected

portions of the channel. The portion of the channel where the trail is experiencing erosion

problems is the only unprotected section of the main channel remaining.

Loss of floodplain area – in combination with increased peak flows and channel incision, fill or

modification of the floodplain increases peak flows and increases velocities and shear stresses in

the remaining channel. Historical mapping suggests that the floodplain on the right (south) bank

of the channel may have been filled in the area experiencing erosion problems.

Backwater and base level changes – although backwater typically reduces velocities and shear

stress, it can contribute to lateral erosion by reducing sediment transport capacity and

saturating banks. Devil’s Gate Dam produces backwater that extends approximately to the area

experiencing erosion problems.

Local channel changes – although the section of channel experiencing problems is mostly

unprotected, areas of rock riprap and construction debris are present on the right bank and

sometimes in the bed of the channel. Revetment of a portion of a channel sometimes leads to

erosion on the opposite bank or in adjacent bank sections. Vegetation along the channel has

been modified with introduction of numerous non‐native species. Native riparian species such

as willow are naturally erosion resistant, but are largely prevented from establishing in the

current channel by a combination of overstory shade from non‐natives, ad hoc revetment, and

instability of the lower banks.


Potential Erosion, Trail, and Habitat Enhancement Treatments

The City has requested that NHC develop some initial ideas on potential treatments of the channel bank that could help stabilize the trail and provide ecological and recreational benefits. The sketches in Attachment A provide simple illustrations of existing conditions and some initial concepts for trail stabilization. The sketches are intended to illustrate concepts that could provide multiple benefits consistent with the City’s objectives for increased safety, reduced maintenance, recreational value, and ecological enhancement while maintaining or improving flood capacity. They are intended as starting points for discussion only and would require more detailed topographic and geotechnical information for development as more comprehensive concepts for the reach of channel experiencing erosion problems. The trail runs in a narrow corridor between the stream and the freeway, and space constraints are likely to be a major factor in determining feasible treatments.

Connection with Arroyo Seco Feasibility Study Objectives

The Corps of Engineers is conducting an Arroyo Seco Watershed Ecosystem Restoration Feasibility Study in partnership with Los Angeles County. The 2011 Scoping Meeting documentation (USACE and LACDPW, 2011) for the feasibility study identified a portion of Flint Wash as one of 9 potential restoration sites in the watershed, and the identified site includes the section of the wash where the trail is currently experiencing erosion problems. The scoping meeting documentation also identified several planning objectives that intersect with enhancement of Flint Wash and stabilization of channel banks along the trail. These include:

Prevent further degradation and improve water quality by reducing stream temperatures, reducing non‐point sources of pollution, and avoiding actions that would mobilize or result in exposure to groundwater contaminants.

Provide ecosystem restoration by restoring high‐value habitat, removing impediments to fish passage, and eradicating invasive species.

Improve riparian habitats by restoring sustainable vegetation within the study area, more natural habitat types, and re‐establish flow and substrate conditions that support aquatic habitat and ecological functions.

Maintain reduction of flood damage and life and property loss through control of bank erosion, reduction of sediment deposition, and improvements to flow capacity within the channel.

Design restoration features that provide incidental benefits by helping mitigate or avoid flood damages by control of bank erosion and improvements to flow capacity within the channel.

Improve recreation opportunities by identifying a balance of open space, recreational trails, and habitat areas.

SUMMARY

Flint Wash bank treatments that combine habitat enhancement, bank stabilization, and recreational trail improvements could help meet water quality objectives by reducing fine sediment sources and providing deeper pools to maintain lower stream temperatures, improve aquatic habitat diversity, improve riparian habitat by replacing non‐native and invasive plants with native riparian species that contribute to bank stability, reduce non‐natural materials (concrete, construction debris) on the banks and in the substrate of the creek to improve aquatic habitat quality, increase reliability of flood protection by increasing conveyance area and reducing the potential for bank failure that could clog the channel, and provide recreational benefits by ensuring regional trail connectivity and providing educational access to restoration actions undertaken as a result of the feasibility study. In addition, a restored Flint Wash could improve connectivity for wildlife from the Arroyo Seco main stem to the more natural tributary channels, aquatic habitats, and upland areas in the San Rafael Hills (Figure 1).

The multiple benefits associated with potential trail stabilization options appear to align well with objectives of the Arroyo Seco Ecosystem Restoration Feasibility Study. Collaboration between the City and USACE/LACDPW is recommended to develop conceptual designs.

We appreciate the opportunity to provide this review.

Sincerely,

Northwest Hydraulic Consultants Inc.

Executive Summary

The city of La Cañada Flintridge is an upper middle-class community of 20,246 residents

(Census, 2010) living within 8.6 square miles. The 210 freeway, a major artery connecting the 5-

interstate freeway intersects city boundaries. Significant landmarks include Jet Propulsion

Laboratory (JPL), Descanso Gardens, and the Flint Canyon Trail. The residents of La Cañada

Flintridge are college educated (68.7%) and the median age is 42.1 years (Census, 2010). Thus,

this community population is deemed to be active based on their age and median income.

The Flint Canyon Trail is used by hikers, equestrians, and bicyclists which allows them

access to enter 40 acres of Cherry Canyon, which is owned by the city of La Cañada Flintridge.

The 2.03 mile-long trail runs through the Flintridge area of the city, connecting Hahamongna

Watershed Park (formerly Oak Grove Park) located in the city of Pasadena on the east. The Flint

Canyon Trail has undergone serious erosion on the downslope due to severe rainstorms and

runoff from the Flint Wash which is located below the trail.

The proposed project includes a preliminary engineering report (survey, topographic base

mapping, geotechnical investigation, design alternatives analysis), public outreach, and final

plans, specifications, and estimate (PS&E) of construction. The project site location is located

along a section of the Flint Canyon Trail near the 210 freeway. This project is especially critical

since a portion of the trail can become destabilized and impact the safety of the 210 freeway.

The total cost to complete final PS&E is estimated at $300,000.

4) SCOPE OF WORK

Since the Flint Canyon Trail Restoration Project is at present essentially only a problem

statement, it will be delivered in four major stages from concept, then outreach, to final design,

and through construction. This application seeks to fund the first three stages through final

design.

Preliminary Engineering/Alternatives Analysis

The concept stage will be a Preliminary Engineering/Alternatives Analysis (PE/AA) in which a

variety of engineering solutions will be developed by the engineering team and analyzed for

cost/benefit and tradeoff analyses. A precise engineering solution can only be determined

through a PE/AA due to the many design considerations involved in a project of this nature such

as follows:

· Potentially sensitive habitat

· Constructability issues

· Agency coordination

· Aesthetics

· Budget

· California Conservation Corps involvement

At this very preliminary stage it is foreseeable that some options for slope protection may

include soldier piles with retaining walls, reinforced shotcrete retaining wall, or gravity pre-cast

concrete modular crib wall. See visual examples of each below in order. Another likely measure

that can be employed to backfill and reinforce areas at the toe of slopes is placement of

gabions. Gabions are steel wire mesh cages filled with rip-rap (large rock aggregate).

Public Outreach

Upon completion of the PE/AA, a public engagement effort with be undertaken to inform

stakeholders and the general public of the various project alternatives and solicit

input. Stakeholder and public input to the project is not likely to guide selection of the high-level

engineering solution since objective engineering analysis, economic analysis, and environmental

screening will quickly narrow the focus of scoping. However, stakeholder and public input will


4

be essential to defining and refining more minor project elements such as aesthetics, signing

standards, and trail amenities.

Final Design

The PE/AA and the selected engineering design alternative will bring the level of design

completeness to approximately 30 percent. The engineering design team will continue with any

additional survey and geotechnical work beyond the PE/AA and produce the final design plans,

specifications, and estimate (PS&E). Design reviews for comment will be conducted at 60, 90,

and 100 percent design completeness. The final PS&E will distinguish between work to be bid

upon by a licensed general contractor and work to be performed by the California Conservation

Corps.

5) PRELIMINARY PROJECT PLANS

In 2012, the city contracted with an engineering consultant to explore probable construction costs

to restore a 2,000-foot section of the Flint Canyon Trail. As part of this project, the planning

process will include preliminary engineering report, survey, base mapping and geotechnical

report to ensure an updated assessment of the area. Deliverables include a preliminary

engineering report with an alternative’s analysis. This report will allow the city to evaluate the

best options to restore the trail. The project also includes an Environmental document to meet

CEQA requirements and a geotechnical report to ensure an accurate representation of the site and

provide recommendations for construction.

6) NEED AND URGENCY FOR THE PROJECT

The city of La Cañada Flintridge is an upper middle-class community of 20,246 residents

(Census, 2010) living within 8.6 square miles. The 210 freeway, a major artery connecting the 5-

interstate freeway intersects city boundaries. Significant landmarks include Jet Propulsion

Laboratory (JPL), Descanso Gardens, and the Flint Canyon Trail. The residents of La Cañada

Flintridge are college educated (68.7%) and the median age is 42.1 years (Census, 2010). Thus,

this community population is deemed to be active based on their age and median income.

This application is for Flint Canyon Trail Restoration which has been an asset to the

community before the city was incorporated in 1976. The trail is used by hikers, equestrians, and

bicyclists which allows them access to enter 40 acres of Cherry Canyon, which is owned by the

city of La Cañada Flintridge. The 2.03 mile-long trail runs through the Flintridge area of the

city, connecting Hahamongna Watershed Park (formerly Oak Grove Park) located in the city of

Pasadena on the east. The Hahamongna Watershed Park is a 1,300-acre open space area that

serves as stream drainage of the Arroyo Seco as it exits the San Gabriel Mountains and flows

south through Pasadena, South Pasadena, and Highland Park to the Los Angeles River. The

Hahamongna Watershed Park hosts five unique habitat zones and a prime oak woodland zone.

To the west and southwest, the Flint Canyon Trail connects to Cherry Canyon in the city of

Glendale. In addition, the Flint Canyon Trail connects to the Arroyo Seco Trail, which leads to

the Gabrielino Trail in the Angeles National Forest abutting the City.


8

The Flint Canyon Trail has undergone serious erosion on the downslope due to severe

rainstorms and runoff from the Flint Wash which is located below the trail. In 2009, the city

completed extensive repairs with grant funds to the upslope of the Flint Canyon Trail which has

also experienced significant erosion. Although the upslope was repaired, the downslope has

continued to erode over time. The city did recently allocate $336,500 towards repairs of the

downslope, however, a long-term solution must be implemented. Without building a permanent

stabilization system for the downslope, the ongoing erosion will compromise the entire slope and

the extensive upslope repairs completed by the city. Should the upslope of the trail become

compromised, it could also potentially destabilize a section of the 210 freeway, which is situated

above the upslope of the trail.

The city has been able to maintain safe access with restrictions through continuous

temporary repairs as long as the downslope by the riverbed holds. However, as time passes, the

potential risks for the downslope’s complete failure could become a reality if funds are not

allocated to make substantial repairs to the trail.

7) DESCRIPTION OF MULTI-BENEFITS

Flint Canyon wash experiences intermittent flows during dry periods largely from urban runoff

and large-volume, high-velocity flows during rainy periods. The nearly year-round presence of

water creates a valuable habitat to support a variety of mammal, bird, reptile, amphibian, insect

and plant species. From an ecosystem standpoint, established species of animals and plants rely

on what is precariously stable conditions in the stream and adjoining banks. Encroachment of

man-made structures such as the 210 Freeway and the adjacent Flint Canyon Trail have confined

the hydraulics of the stream to a fixed condition that does not allow natural processes to alter the

tastream without radical destructive changes. In order to preserve habitat stability in the stream

and adjoin banks, slope stabilization is needed by means of artificial structural solutions. The

types of solutions themselves can have a significant benefit to the stream-bottom ecosystem by

providing plant friendly media for growth as can be found in gabion structures and the open

spaces behind modular crib walls.

From a watershed protection standpoint, stabilization of the slopes above the stream will prevent

washouts of sediment that will ultimately make their way to Devils Gate Reservoir. Although


9

the amount of sediment potentially tributary to Devils Gate Reservoir would be very small, every

bit helps in controlling sediment inflows to Devils Gate Reservoir.

8) PURPOSES OF PROPOSITION 68

The purposes of Proposition 68 are generally covered in the headings of Chapters 2 through 11

the enabling legislation, SB 5, for Proposition 68 as follows:

• CHAPTER 2. Investments in Environmental and Social Equity, Enhancing California’s

Disadvantaged Communities

• CHAPTER 3. Investments in Protecting, Enhancing, and Accessing California’s Local

and Regional Outdoor Spaces

• CHAPTER 4. Restoring California’s Natural, Historic, and Cultural Legacy

• CHAPTER 5. Trails and Greenway Investment

• CHAPTER 6. Rural Recreation, Tourism, and Economic Enrichment Investment

• CHAPTER 7. California River Recreation, Creek, and Waterway Improvements

Program

• CHAPTER 8. State Conservancy, Wildlife Conservation Board, and Authority Funding

• CHAPTER 9. Ocean, Bay, and Coastal Protection

• CHAPTER 10. Climate Preparedness, Habitat Resiliency, Resource Enhancement, and

Innovation

• CHAPTER 11. Clean Drinking Water and Drought Preparedness

This project, upon future completion of construction, fulfills the purposes of Chapters 3, 5, 6, 7,

and 10.

9) GREENHOUSE GAS EMISSIONS REDUCTION TARGETS

This project is not anticipated to have substantial or significant effect on reducing greenhouse

gas emissions.

10) PROMOTION OF RELEVANT REGIONAL AND STATE PLANS AND POLICIES

This project has significant relevancy with federal, state and local agencies. At the federal

level, the Army Corps of Engineers completed a preliminary study that included the Flint Wash

as a potential project. The primary purpose of the study was to determine if there would be


10

federal interest in providing solutions to water and land-related issues in the watershed.

Additionally, the trail itself is part of the proposed, “Rim of the Valley” trail. Congress directed

the National Park Service to study the mountains encircling the San Fernando, La Crescenta,

Santa Clarita, Simi, and Conejo Valleys in Los Angeles and Ventura counties. Therefore, there is

substantial federal interest in the Flint Wash area but final conclusions are still pending and

funding is uncertain at this time.

Caltrans has both safety and financial interests in ensuring that the underpinnings of the

freeway do not collapse, which could occur as a result of lack of repair to the downslope. There

is also regional significance to the project. The city of Pasadena borders the city and if the trail is

lost, major trail connectivity will also be lost. Additionally, the water flow of the Flint Wash is

shared with Pasadena. Furthermore, La Cañada High School, a local high school, utilizes the trail

for athletic training.

11) MATCHING FUNDS

At present this stage of the project does not yet have a commitment of matching funds, however,

arrangements are presently underway to develop a plan by which the non-profit La Canada

Flintridge Trails Council can make an in-kind contribution.

12) BENEFITS TO DISADVANTAGED COMMUNITY

Based on the regional significance of the trail, the benefits of the project will greatly

benefit neighboring communities beyond the La Cañada Flintridge boundaries. According

Exhibit 2 - California State Parks Community Fact Finder tool (accessed November 28, 2018),

within a ½ mile radius there are no disadvantaged communities. However, increasing the

boundary to a 3-mile radius, the area would start to encompass a western portion of Pasadena

which does include a disadvantaged community and to a greater extent a severely disadvantaged

community further southwest. According to the legend in Exhibit 2, the disadvantaged

community is shaded in purple, while the severely disadvantaged community is shaded in

mustard color. By ensuring the trail is restored, recreational opportunities for disadvantaged

communities will remain accessible.


11

EXHIBIT 2- COMMUNITY FACT FINDER TOOL

13) PARTNERING WITH LOCAL OR STATE CONSERVATION CORPS

The city of La Cañada Flintridge will partner with the California Conservation Corps LA

Satellite Center. Based on Proposition 68 guidelines, it is encouraged by the Conservancy to use

the “Conservation Corps whenever feasible when implementing restoration and ecosystem

protection projects.” Since this project entails ecosystem protection and restoration, it is a natural

fit to incorporate the Conservation Corps into this project. A Corps Consultation request was

submitted and approved by the agency (see Attachment A). In the construction phase, a

component of work will be completed by the California Conservation Corps. Based on the

budget described in Table 1, tasks 5.02, 5.16, 5.17, and 5.18 will be completed by the California

Conservation Corps.

14) DESCRIPTION OF NEW OR INNOVATIVE TECHNOLOGY OR PRACTICES

The preliminary engineering alternatives analysis combined with input from public outreach will

determine the method by which slopes will be stabilized.

15) MONITORING AND REPORTING OF PROGRESS AND EFFECTIVENESS


12

Since the entire project, when constructed, will be largely an engineering structural solution,

monitoring for effectiveness will be mainly a matter of physical and visual inspection of the built

structure. As this phase of the project for which grant funds are sought only involve production

of final design plans, an equivalent means of monitoring and reporting for effectiveness would

be through professional peer review. A third party team of professionals can be afforded in the

budget to provide secondary opinions of engineering solutions at the conceptual stage and

through final design.

16) COMMON GROUND PLAN

Based on the Common Ground Plan adopted in October 2001, this project is consistent

with several goals listed within multiple subcategories in the Guiding Principles. The following

goals will guide the planning and outreach of the project:

LAND: Grow a Greener Southern California

Improve Habitat Quality, Quantity, and Connectivity

Connect Open Space with a Network of Trails

Encourage Sustainable Growth to Balance Environmental, Social, and Economic Benefits

PLANNING: Plan Together to Make it Happen

Involve the Public Through Education and Outreach Programs

Utilize the Plan in an On-going Management Process

Since the project has regional significance, there will be multiple opportunities for public participation

through community input meetings and stakeholder / land owner meetings. The purpose of the outreach

phase is to ensure residents and stakeholders are informed and educated to the restoration of the trail.

17) HOW PROJECT WILL FURTHER THE SANTA MONICA MOUNTAINS

CONSERVANCY STRATEGIC OBJECTIVES

The Santa Monica Mountains Conservancy is guided by the goal of interlinking a network of

parks, trails, and open space for public use and wildlife habitat, ensuring future open space and

recreational lands in Los Angeles and Ventura counties. This project ensures that the Flint

Canyon Trail remains open and accessible to all who wish to use it. Should parts of the trail close

due to extensive erosion, connectivity to Cherry Canyon and Hahamongna Watershed Park

would be significantly impacted and limit recreational opportunities for local residents.


13

Furthermore, since part of the trail runs along the 210 freeway, any further erosion can lead to

destabilization of the 210 freeway, thus significantly compromising the safety of the supports for

this important transportation artery in the area.

18) SCOPE OF WORK DESCRIPTION TO PROTECT OR ENHANCE URBAN CREEK

The description of the project in response to application Items 4 through 7 explain how this

urban creek will be protected.
