AGENDA TITLE: Adopt Resolution Approving River Parkways Grant Application
MEETING DATE: September 16, 2015
PREPARED BY: Parks, Recreation, and Cultural Services Director
RECOMMENDED ACTION: Adopt resolution approving River Parkways Grant Application.
BACKGROUND INFORMATION: The State's Natural Resources Agency recently accepted
applications for its River Parkways grant program, which provides
funding for a variety of projects ranging from wildlife habitat
restoration to creating recreational trails. The City, through the Parks, Recreation and Cultural Services
Department, is seeking maximum grant funding of $500,000 to build a riverfront trail and a new
kayak/canoe launch area, and restore the amphitheater retaining wall that has collapsed into the river.
Statewide, $7.6 million is available in this year's round of funding. This is likely the final round of grants
available through the River Parkways program, which was initiated in 2004. The City did not succeed in
its 2008 and 2011 River Parkways applications for funds to repair the eroding riverbank near Pigs Lake.
The schedule to develop the scope of a project and then write the application was short. The Natural
Resources Agency announced the grant availability in May, and the Recreation Commission voted in
June to have staff focus on obtaining grants for Lodi Lake Park. ICF Jones & Stokes was hired in July to
identify a project, and again in August to write the application, which was submitted on the September 1,
2015 deadline. Due to the short grant schedule, the Natural Resources Agency will accept the attached
supporting resolution following the application deadline.
As indicated in the joint shirtsleeve session of the City Council and Recreation Commission on August
25, 2015, the Lodi Lake Park North Side Restoration and Bank Stabilization Project would create 3,900
linear feet of trail that connect the major recreation areas, from the entrance of the Nature Area all the
way around the Youth Area. It also would introduce vegetation above and below the waterline to combat
erosion, which has resulted in loss of park land and the collapse of the Williamson Youth Area
amphitheater wall. Hughes Beach would have a designated kayak/canoe launch site that would prevent
further erosion, and the trail would also have informational signs to explain the science behind riverfront
erosion. Based on comments at the joint shirtsleeves meeting, the split -rail fence was removed as an
element of the proposed project. A copy of the project description is attached.
The City is committing a match valued at up to $171,160. Most of it would be staff time related to design,
engineering, in-house labor for irrigation modifications and project management. Donated plant materials,
volunteer labor and potential additional permitting costs are calculated in the total value.
The application was submitted with letters of support from Assemblyman Jim Cooper, East Bay MUD, the
Lower Mokelumne River Stewardship Committee, Headwaters Kayak Shop and other Lodi residents.

Lodi Lake Park North Side Restoration and
Bank Stabilization Project Description
Introduction
The City of Lodi Parks, Recreation, and Cultural Services Department (hereafter referred to as "the
City") operates and maintains Lodi Lake Park, a 43 -acre regional park that features swimming,
boating, and picnicking areas; playgrounds; views of the Mokelumne River; and a riverfront
amphitheater. The City also operates and maintains the adjacent Lodi Lake Wilderness Area, which
preserves 58 acres of riparian and natural open space and features 2.3 miles of paved and unpaved
trails (see location map provided in Figure 1).
Erosion of the lake and river margins defining the park has become an issue of concern for the City,
especially along the north side of the park where erosion along the bank of the Mokelumne River is
causing loss of park land and is threatening park infrastructure (photos are shown in Figure 2).
Observations by City staff indicate that this erosion is being accelerated by people, pets, and small
watercraft entering and exiting the river along the shallow, grassy bank, despite signs posted
expressly prohibiting swimming, wading, and boating from the riverbank.
The City is proposing the multi -benefit Lodi Lake Park North Side Restoration and Bank Stabilization
Project to enhance native habitat, slow erosion, discourage public access in key bank locations that
need time to stabilize, direct proper public use of the river bank, formalize river access areas,
enhance pedestrian circulation through the park, and provide learning opportunities for park
visitors through an education component. This project description more explicitly details the
project's goals and objectives and the design concept to achieve them and provides information on
existing conditions to support the need for action.
Goals and Objectives
The City has defined a common vision and list of goals for the project. The principal characteristics
of this vision are listed as individual goals below.
Goals
The following characteristics serve as the basis for the project work.
• Enhance river bank habitat for wildlife.
• Prevent erosion and further soil loss.
• Discourage inappropriate and illegal use of the shoreline that contributes to soil loss.
• Preserve the existing river bank.
• Restore park infrastructure damaged by erosion or threatened by soil loss.
• Formalize a designated access point to the Mokelumne River from the project area.

• Allow for passive recreation (walking, running, and biking), educational opportunities, and
group use areas.
• Maintain views of the Mokelumne River from key gathering points in the park.
Implement improvements in the most sustainable, eco -friendly, and environmentally
responsible manner possible.
Objectives
Understanding the intended vision for the project has led to the development of the following
objectives, reflective of the goals, and will guide the project planning and implementation process.
• Establish erosion control plantings along the river bank with the majority of plants having
maximum height of 36 inches.
• Change management approach to buffer area along the river bank.
• Provide shaded riparian aquatic (SRA) cover and dissipate energy along the river bank by
planting woody vegetation such as willows (Salix sp.) or buttonwillows (Cephalanthus sp.).
• Provide fish and waterfowl habitat and dissipate energy along the river bank by planting
emergent vegetation.
• Formalize the hand launch boat ramp area at Hughes Beach by installing a concrete ramp.
• Establish a pedestrian path, constructed with pervious surfacing, connecting the Youth Area,
Rotary Area, and Hughes Beach.
• Establish wildlife and water viewing points along the river bank with seating areas.
• Establish interpretive signs or kiosks at wildlife and water viewing point and along pedestrian
path.
• Abandon and cap irrigation system where it is in water or no longer needed.
• Shore up and fix youth area amphitheater stage.
• Implement plantings without the use of pesticides, herbicides, or artificial fertilizers.
• Implement infrastructure improvements using recycled materials where possible or feasible.
• Do not plant species considered invasive by the California Invasive Plants Council (Cal -IPC) or
plants considered weedy or listed in Weeds of the West.
Existing Conditions
Park Facilities and Use
The north side of Lodi Lake Park features formal picnic/gathering gazebos at Hughes Beach, the
Rotary Area, the Youth Area, and Parson's Point. The first photo in Figure 3 shows a view of the
Rotary Area, with the Mokelumne River flowing behind. The Youth Area also features a playground
and an amphitheater, which is used by various community groups for interpretive and educational

programs, musical performances, and club meetings. The second photo in Figure 3 shows
representatives from Zoo to You demonstrating native and nonnative California animal species at
the amphitheater during an event sponsored by the San Joaquin County Resource Conservation
District. A motorized boat launch near Parson's Point allows boaters to enter Lodi Lake. There is no
formal pedestrian trail or path connecting these features.
Outside of the sanctioned uses of the park, visitors are often observed along the shore of the
Mokelumne River (particularly along the Rotary Area) wading, swimming, launching canoes and
kayaks, and even piloting personal motorized watercraft (e.g., SkiDoos) up onto the bank. These
activities take place despite posted signs expressly prohibiting swimming, wading, and boating from
the riverbank and the efforts of City staff to direct kayakers and canoe users to launch from the
Hughes Beach area. The third photo in Figure 3 shows the Hughes Beach launch area for canoes and
kayaks.
Hydrology
The Mokelumne River, which is East Bay Municipal Utility District's (EBMUD's) primary water
source to serve over 1.3 million people, provides, on average, just 2.5% of total inflow into the Delta.
The Mokelumne River is managed by a set of interrelated agreements. These include the 1998 Joint
Settlement Agreement (JSA) between EBMUD, the California Department of Fish and Wildlife
(CDFW) and the U.S. Fish and Wildlife Service (USFWS), setting minimum flow releases from
Camanche Reservoir to benefit the fishery ecosystem (Federal Energy Regulatory Commission
1996). The upper Mokelumne River extends from its headwaters to Pardee Reservoir; the lower
Mokelumne River refers to the portion of the river below Camanche Dam. The lower Mokelumne
River is highly regulated and, thus, does not experience a wide range of flow conditions.
Minimum flows that would occur in the Mokelumne River vicinity of the project area (i.e., the lower
Mokelumne River) are set forth by the ISA. The minimum flow releases are based on the time of year
and water year types and, as such, are variable but range between 100 and 325 cubic feet per
second (cfs). The maximum release allowed out of Camanche Reservoir (by U.S. Army Corps of
Engineers's (USACE's) flood control regulations for that channel) is 5,000 cfs, which typically only
occurs in late spring and early summer after heavy snowfall winters (most recently in 2011, 2006,
and 1997).
Lodi Lake Park is situated on the lower Mokelumne River approximately 20 miles downstream of
Camanche Reservoir. Woodbridge Dam, operated by the Woodbridge Irrigation District, is located
approximately 2,200 feet downstream of Lodi Lake Park, and dam operations keep water levels in
the lake and in the river at a steady elevation for most of the year. Historically, the lake and river
water level was kept at 39 feet NGVD (National Geodetic Vertical Datum 29). In 2006, modifications
were made to Woodbridge Dam that allowed for more precise control of water levels, and since that
time, the lake and river have been kept between 40 and 41 feet NGVD. During an approximate 3- to
4 -week fish ladder maintenance window each February, WID drains the reservoir. This causes the
water surface elevation in the lake and river fall approximately 10 to 13 feet and leaves the river
back in its natural channel (Hood pers. comm. [a], [b], and [c]).
Existing Vegetation
The vegetation within the proposed project area is primarily overstory trees and herbaceous
groundcover. There is little to no midlevel vegetation (shrubs). Turf grass is the current dominant
Lodi Lake Park North Side Restoration and 3 August 2015
Bank Stabilization Project Description ICF 00459.15
City of Lodi Parks, Recreation, and Cultural Services
Department
vegetative cover along the river bank from the water margin inward covering all active and passive
use spaces within the project area. Turf is a resource -intensive vegetative cover in the Central Valley
requiring high inputs of water from irrigation, herbicides to control broadleaf weeds, and fertilizer
to maintain healthy growth. Turf requires mowing weekly in active growth phases and generates
green waste (biomass) which must be composted or disposed of once collected. Turf species
observed growing in the project area include Bermuda grass (Cynodon spp.), perennial ryegrass
(Lolium spp.), and Kentucky bluegrass (Poa pratensis). Turf does not thrive in saturated soils and
becomes vulnerable to disease and weeds (Regents of the University of California 2015). The
average rooting depth of the majority of turf species present is 12 inches (Regents of the University
of California 2009). The result of growing turfgrass along river bank and lake shoreline is that the
vegetation layer is only 3 inches above ground and 12 inches below ground. The rooting depth
below ground likely extends even less to the depth of the water table. One of the causes of the
erosion of the river bank is the lack of vegetation tall enough to dissipate energy from flowing water
and boat wakes, and the lack of deep roots to bind soil during peak flows. Figure 4 shows the typical
existing riverbank section in the eroding areas.
Where overstory exists in the rest of the project area, the trees are a mixture of historic native
riparian trees, more recently planted native riparian trees, and mature ornamental trees. Fremont
cottonwood (Populus fremonth) comprise the majority of historic overstory trees. Several young
valley oaks (Quercus lobata) are growing in the proposed project area. The entry road is lined with
mature London plane trees (Platanus x acerifolia), and other ornamental trees, such as contorted
willow (Salix matsudana 'Tortuosa'), are growing in the lawn, around parking lots, and shading the
park.
Erosion
Observations by City planning and maintenance staff indicate that, in addition to insufficient
vegetation to bind soil and dissipate energy from flowing water, much of the erosion along the
Mokelumne River at the north side of the park is caused by people, pets, and small watercraft
entering and exiting the river along the shallow, grassy bank (uses specifically prohibited by the
City's municipal code). Direct access and associated trampling in riverine environments can lead to
loss of vegetative matter that protects the ground from large -magnitude precipitation events and
bank erosion resulting from trampled ground that becomes compacted enough to prohibit the
establishment of vegetation but not so much as to prohibit the contribution of soil particles to the
water column from high velocity flows. Direct access to the banks can also cause mass failure (loss of
a large section of bank through gravitational processes), once the resisting force of the bank is
outweighed by the tractive forces acting upon it. Additional fluvial erosion is likely caused by boat
wakes from motorized watercraft in the Mokelumne River.
Operational changes at the Woodbridge Dam since its reconstruction in 2006 have most likely
accelerated loss of bank material because of higher water levels and the resultant higher levels of
soil saturation; City staff has observed increased rates of erosion since 2006. The soils comprising
the river bank form a cohesive material that appears to be failing en masse. This erosion pattern is
consistent with mass bank failure from saturation and gravitational forces, whereby increased pore
pressures lead to instability. Saturation is a different mechanism than hydraulic erosion, where the
toe of the bank is eroded by shearing forces (fluvial erosion), although the two processes can act in
concert with each other. Since modifications to the dam downstream of the project site allowed for
raised local water surface levels, the soils have likely become considerably more saturated than in
the past, which would contribute to bank failure. The failure could be exacerbated by the drawdown

of the reservoir during the February dam maintenance window when there is a pressure differential
between the saturated banks and the open air. Foot traffic along the bank, as described above, is
compacting the soils further, leading to even higher pore pressures.
A recent survey performed by City staff shows shoreline losses of to 15 feet in some locations over
the past 10 years. Figures 5 and 6 contain the results of a recent survey performed by a City
engineer on July 14, 2015, and show how much bank loss has occurred since the basemap was
prepared in 2001-2002. In some locations, there has been shoreline loss of up to 15 feet in 13 years.
Measurements were taken for this survey through triangulation methods from fixed hardscape
surface points.
This erosion is of concern to the City not only because of the loss of usable park land, but also
because the erosion is starting to threaten the safety and functionality of park infrastructure. The
photos in Figure 2 show some examples of threatened infrastructure, including exposed irrigation
lines, erosion encroaching on the picnic gazebo in the Rotary Area, and erosion undermining the
amphitheater stage in the Youth Area.
Failure of Amphitheater Stage
The Youth Area amphitheater is comprised of a set of arced concrete seatwalls oriented riverward
towards a raised stage area. The raised stage is formed by an approximately 2 -foot -tall poured
concrete retaining wall. The stage surface is turfgrass planted over soil. The stage is approximately
50 feet long. The river shoreline immediately abuts the riverside retaining wall of the stage for
approximately 38 feet of its length. Historically, the wall and the river were separated by land.
Figure 6 contains the results of a recent survey performed by a City engineer, and shows how much
bank loss has occurred since the basemap was prepared in 2001-2002. Between the riverside of the
stage and the shoreline, there has been a loss of up to 5 feet in 13 years.
The northern half (approximately 25 feet) of the retaining wall has begun to fail and collapse, with
the top of the wall tilting outward to the river (as shown in Photo 4 of Figure 2). In addition to
erosive forces on the waterside of the wall, saturated soil conditions under and behind the wall due
to the changes in site hydrology (raised water levels), are also likely contributing to failure of the
wall. The wall was not designed to retain saturated soils and does not appear to contain any features
to allow the retained soils to drain. The saturated retained soils place lateral pressure outwards
towards the face of the wall, and the pressure increases during the February drawdown period of
the reservoir. Without a drainage mechanism behind the wall to drain the water and release
pressure, the force is left behind the wall pushing the wall out and is most likely contributing to wall
failure.
Design Concept
The design concept for the project area is based on the Goals and Objectives listed above. The
project should establish multi -benefit erosion control plantings along the river bank providing
energy dissipation and habitat for fish and waterfowl. The erosion control plantings would require a
change in vegetation management and will change the river access behavior of recreationists. A
designated entry point to the river for hand -launch boats would be formalized along with several
viewing points. Existing park infrastructure damaged by erosion at the park would be remediated or
enhanced where feasible. Circulation through and vegetation management within the project area

would be enhanced by development of a pedestrian path traversing the project area. An
environmental education component of the design would address the needs of visitors from a
variety of age groups interested in learning with engaging and relevant exhibits within the project
area. Figure 7 provides a conceptual plan view of the proposed project features.
Erosion Control/Bank Stabilization
The erosion control envisioned for the river bank would rely primarily on the establishment of
targeted native emergent vegetation along the perimeter of the waterway that is experiencing bank
loss. The erosion control plantings would be multi -benefit and provide bank protection via binding
the soil and serving to dissipate energy from river flows and boat wakes; and would provide habitat
for fish, water fowl, and other wildlife. The erosion control plantings would also serve to improve
water quality of runoff leaving the park and of the Mokelumne River. Emergent herbaceous plants
would be established throughout the majority of the erosion control plantings (as shown on Figure
8).
Riparian willow scrub would be established along locations where there are not primary views to
the open water. Where there are premium views to the open water from fixed locations of high
duration use (e.g., picnic shelter, day use facility) views to the open water will be maintained as
much as feasible through establishment and management of emergent species with a height of 36 to
48 inches. The native emergent and willow scrub plants are tolerant of saturated soils, high water
tables, anaerobic growing conditions, the local climate, and provide optimum habitat for wildlife.
Roots of native emergent and riparian willow scrub plants bind soil and sequester soil particles once
established. Plant palettes for the bank stabilization areas are provided in Tables 3-1 and 3-2.
The erosion control approach would be planting -based and not rely on structures such as rootwads,
toe logs, or other large woody material. The reason for this approach stems from the fact that the
stream banks adjacent to the Mokelumne River are not tall enough (approximately 1 to 3 feet) for
rootwad installation. Furthermore, the level of soil moisture within the stream banks is very high
due to the high water surface elevation in the river and may not support structural installation over
the long term.
The area to be planted would be open water areas up to 12 inches deep in the Mokelumne River and
areas on land between the river bank and the proposed path. For landside plantings, existing turf
would be removed to a depth of 4 inches, and 4 inches of topsoil would be imported and
incorporated into existing soil prior to planting. Mowing, chemical application, and other turf
management practices would cease after time of planting. Instead the bank stabilization planting
areas would be managed for native plantings.
Plants would be transplants or cuttings from onsite locations or container plants, or container plants
purchased from a local native plant nursery. If possible, container plants would be grown from seeds
or cuttings collected at or near the project site in order to populate the site with species ecotypes
that are adapted to local ecological conditions. Plants would be planted in the wet season after
rainfall has saturated the soil. Planting holes in open water areas would be hand -excavated with a
shovel or trowel. If tules and/or cattails are imported from a nearby site instead of a nursery, they
may be installed using excavators.
In order to minimize adverse boat wake effects on new plantings, the City intends to request that
San Joaquin County reduce the posted boat speed limit on the Mokelumne River to 5 miles per hour
through the project area during the plant establishment period. Wetland plantings are most

increase in mass, and the accumulation of sediment begins, the wetland plants will be less affected

Mokelumne River Access
Access to the Mokelumne River would be provided by formalizing the hand launch boat ramp area at
Hughes Beach, constructing wildlife and water viewing points, and establishing and maintaining
lower growing (less than 36 to 48 inches tall) emergent vegetation along the river bank premium
viewing locations to preserve visual access to the river from the park.
The hand launch boat ramp would be formalized to direct and concentrate pedestrian boating
ingress and egress from the project area to the Mokelumne River at a designated point on the river
bank. The intent of a singular designated ingress/egress location would be to eliminate the
unsanctioned access to the river bank currently exercised at the river and reduce or eliminate this
behavior and resultant erosion, which is one of the primary causes of bank instability throughout
the project area. Signage directing small watercraft boaters to the hand launch boat ramp would be
installed at regular intervals near the waterway along the proposed pedestrian path, described in
the next section.
The hand launch boat ramp would be improved and could be either poured concrete or a flexible
concrete mat, with an approximate 15 by 25 foot launch area. Construction of the ramp would take
place while the Woodbridge Dam is open during the rainy season (the fish ladder maintenance
period) and water levels are low. A poured concrete ramp would involve implementing a design that
prevents erosive undercutting or breaking of ramp edges and isolating the wet concrete from waters
of the state until it is fully hardened. Construction of a poured concrete ramp would involve
excavation of the soil, installing an aggregate base layer, installing reinforcing steel bars and wooden
concrete forms, pouring and finishing concrete, removing concrete forms, and regrading soil and
replanting vegetation along the ramp edges.
Another ramp surface option would be a flexible concrete mat, which would involve the installation
of articulated concrete mats of interlocking concrete blocks bound by revetment cables.
Construction of an articulated concrete mat would involve excavating the soil, installing an
aggregate bedding layer, placing concrete mats, installing aggregate backfill (if required), and

regrading soil and replanting vegetation along the ramp edges. The ramp would be connected to the
pedestrian path by an Americans with Disabilities Act (ADA) -accessible path of travel.
The wildlife and water viewing points would be extensions of the pedestrian path described below.
The points would be surfaced with decomposed granite bordered by a mowband. The points will be
ADA accessible. The points could have interpretive signs or kiosks as described later under
Environmental Education. A seat wall or prefabricated park bench could provide seating at each
point.
Infrastructure Remediation and Enhancement
Erosion and saturated soil conditions have been observed to be affecting park infrastructure
including irrigation systems and the youth amphitheater stage.
Prior to remediating the irrigation system, the existing irrigation design would be updated based on
current pipe layout and system configuration. Irrigation head and pipes now located out in the river
channel or water would be removed and lines capped. Where possible, existing irrigation circuits
would be combined. Existing irrigation heads would be retrofitted with new heads or nozzles that
are higher efficiency and lower volume. Temporary irrigation needs of erosion control plantings
could be provided by the existing system using high efficiency low flow irrigation heads and utilize
irrigation valves no longer needed because of change in vegetation type along the river bank and
removal of the portions of the irrigation system in the river channel.
The existing Youth Area amphitheater stage requires repair by reconstruction of the stage retaining
wall nearest the river. The stage retaining wall would be removed and the reconstructed wall would
require a new footing, weep holes, drainage pipe, and engineered backfill to reduce lateral pressure
from any water trapped behind the wall. Excavation for the new footing, wall, drainage pipe, and
engineered backfill would take place while the Woodbridge Dam is open during the rainy season
and water levels are low.
Prior to the reconstruction of the stage retaining wall, a portion of the existing stage soil would be
removed against all existing walls, weep holes would be drilled into the walls, and a drainage pipe
would be added at the base of all four sides. The new footing and retaining wall would be
constructed of reinforced poured concrete with a finish to match the existing structure as much as
feasibly possible. The new retaining wall would be tied into the existing stage retaining walls with
steel reinforcing bars and would have weep holes. Once the concrete wall is cured, the soil excavated
from the stage during the repair process would be replaced with engineered fill material. The
engineered fill material would have larger pore space and drain more quickly than existing soil, thus
reducing pressure during periods of soil saturation behind the wall and allowing for quick drainage
afterwards. The engineered material could be planted directly with turfgrass, or the top 4 to 6
inches of soil could be mixed with existing backfill for planting if required for best plant growth
depending on engineered soil properties. Soil excavated from the stage could be used to create a 5
foot wide bench or terrace sloped at no greater than 5:1 adjacent to the retaining wall and would be
planted as described earlier under Erosion Control/Bank Stabilization.
Pedestrian Path
Circulation for recreationists through the project area would be provided by a new pedestrian path
constructed from the Youth Area to Hughes Beach. The path would be approximately three-quarters
of a mile long and would demarcate the boundary between distinct vegetation management areas.
Lodi Lake Park North Side Restoration and 9 August 2015
Bank Stabilization Project Description ICF 00459.15
City of Lodi Parks, Recreation, and Cultural Services
Department
Between the path and the river bank, the vegetation would be managed for providing erosion
control, energy dissipation, and habitat for fish and waterfowl. Between the path and the vehicular
roads and parking areas, the vegetation would be managed for active and passive park use. The
pedestrian path would accommodate runners, joggers, and walkers. The path would be ADA
accessible and constructed from decomposed granite. A mowband would separate the path from the
vegetation on both sides for ease of future maintenance.
The pedestrian path would provide access to the improved hand launch boat ramp at Hughes Beach
and wildlife and water viewing points. Group use areas within the project area would be linked by
the path. The path route would be selected to interface with vehicular roads and parking lots as
infrequently as possible. If the path must cross or interface vehicular roads or parking lots, the path
intersection would be marked clearly with signs and demarcated with white reflective paint on the
vehicular pavement surfacing. Installation of bollards may be necessary at these locations to prevent
vehicle access to the path. The path would tie into existing sidewalks and pedestrian routes in Lodi
Lake Park and become part of the park's circulation infrastructure.
Environmental Education
The interpretive plan for the project identifies possible themes for education, goals and objectives,
and appropriate media to interpret Lodi Lake Park's features, its role in the Mokelumne River
watershed, and its place as a wildlife and nature sanctuary. The intent of the interpretive plan at the
project is to increase the public's awareness of the fragility and importance of Central Valley
riparian and riverine systems.
Interpretive Program Themes
Below are possible themes for interpretive elements of the project.
• The Mokelumne River watershed and river hydrology.
• The native plant communities of the Lodi area and associated wildlife.
• The history of the Mokelumne River and Lodi Lake.
• Native American use of the Mokelumne River watershed.
• A hybrid of these themes.
Interpretive Program Objective
The objective of the interpretive program is to provide visitors with a deeper appreciation and
understanding for the sense of place provided by Lodi Lake Park. The development of an inclusive,
fair, factual, and unbiased interpretive program reaching out to a broad and varied audience will
help achieve this objective.
Interpretive Media
The project interpretive program could use a combination of posted stationary interpretive signs
and loose-leaf printed brochures at kiosks. The posted stationary signs could be a combination of
freestanding signs and signs mounted to interpretive kiosks. Imagery on stationary signs could be
freehand drawings, photographs, computer generated diagrams, or a combination thereof.
Interpretive kiosks could contain bins for storing and distributing informational brochures. The
Lodi Lake Park North Side Restoration and 10 August 2015
Bank Stabilization Project Description ICF 00459.15
City of Lodi Parks, Recreation, and Cultural Services
Department
project's interpretive program would complement the existing interpretive displays already in place
at the Lodi Lake Park Nature Center near the park entrance and near the trailhead for the Lodi Lake
Nature Area, which is located adjacent to the Hughes Beach area.
Permitting Required
Implementation of project elements that occur below the ordinary high water mark (OWHM) in the
Mokelumne River will require a Clean Water Act (CWA) Section 404 permit from USACE and a
Section 1600 streambed alteration agreement from CDFW. Permits can require several months to
apply for and obtain; the process is time- and labor-intensive. Actions proposed in the project that
could trigger these permits are the hand -launch boat ramp upgrade, amphitheater repair, and
mechanical installation of emergent vegetation, if necessary. Planting by hand in areas below the
OHWM are exempt from Section 404 requirements.
Fill Placement in Waters of the United States (CWA Section 404)
CWA Section 404 regulates the discharge of dredged and fill materials into waters of the United
States, which are oceans, bays, rivers, streams, lakes, ponds, and wetlands, including areas within
the OHWM of a stream. Project proponents must obtain a permit from USACE for all discharges of fill
material into waters of the United States before proceeding with a proposed activity. The project
may be eligible for a nationwide 404 permit (NWP), which provides for a streamlined permitting
process, and are issued to cover particular fill activities. Each NWP specifies particular conditions
that must be met for the NWP to apply to a particular project. The proposed project may be eligible
for one or more of the following NWPs.
• NWP 03—Maintenance.
• NWP 13—Bank Stabilization.
• NWP 18—Minor Discharges.
• NWP 27—Aquatic Habitat Restoration, Establishment, and Enhancement Activities.
• NWP 36—Boat Ramps.
• NWP 42—Recreational Facilities.
Compliance with CWA Section 404 requires compliance with several other environmental laws and
regulations. USACE cannot issue or verify the use of any permit until the requirements of the
National Environmental Policy Act (NEPA), the Endangered Species Act (ESA), and the National
Historic Preservation Act (NHPA) have been met. In addition, USACE cannot issue or verify any
permit until a water quality certification or a waiver of certification has been issued pursuant to
CWA Section 401. Below are additional permit requirements triggered by Section 404 compliance.
• NEPA. NEPA requires Federal agencies to make a series of evaluations and decisions that
anticipate adverse effects on environmental resources. This requirement must be fulfilled
whenever a federal agency proposes an action, grants a permit, or agrees to fund or otherwise
authorize any other entity to undertake an action that could possibly affect environmental
resources. If the project is eligible for a NWP, no further NEPA compliance would be required, as
NWPs are issued under an already completed programmatic NEPA analysis. If the project is not
Lodi Lake Park North Side Restoration and 11 August 2015
Bank Stabilization Project Description ICF 00459.15
City of Lodi Parks, Recreation, and Cultural Services
Department
eligible for a NWP, then a NEPA analysis will need to be performed; likely a streamlined
environmental assessment/finding of no significant impact (EA/FONSI) would be adequate.
• Section 7 of the Endangered Species Act. ESA (1973) and subsequent amendments provide
for the conservation of listed endangered or threatened species or candidates for listing and the
ecosystems on which they depend. USFWS has jurisdiction over federally listed plants, wildlife,
and resident fish, and the National Marine Fisheries Service (NMFS) has jurisdiction over
anadromous fish and marine fish and mammals. Section 7 of ESA requires federal agencies, in
consultation with USFWS and NMFS, to ensure that project -related actions do not jeopardize the
continued existence of endangered or threatened species or result in the destruction or
significant modification of the critical habitat of these species. The project may qualify for
informal consultation with USFWS and NMFS and issuance of a letter stating that the project is
"not likely to adversely affect" listed species. However, formal consultation, preparation of a
biological assessment, and issuance of a biological opinion may be necessary. The California
Association of Resource Conservation Districts has a safe harbor agreement with USFWS
covering valley elderberry long horn beetle in the lower Mokelumne River watershed. The City
has begun the process of signing on to the agreement, and if executed in a timely manner, the
safe harbor agreement may speed consultation with USFWS on the project.
• National Historic Preservation Act of 1966, as amended. NHPA requires Federal agencies to
take into account the effects of federal and federally -permitted undertakings on historic
properties. Section 106 of the NHPA describes the process for identifying and evaluating historic
properties; for assessing the effects of federal actions on historic properties; and for consulting
to avoid, reduce, or minimize significant effects. The term historic properties refers to cultural
resources that meet specific criteria for eligibility for listing on the National Register of Historic
Places (NRHP). This process does not require historic properties to be preserved but does
ensure that the decisions of federal agencies concerning the treatment of these places result
from meaningful consideration of cultural and historic values and the options available to
protect the properties. Under these requirements, the area of potential effect of the selected
project is inventoried and evaluated to identify historical, archeological, or traditional cultural
properties that have been placed on the NRHP and those that the agency and State Historic
Preservation Officer (SHPO) agree are eligible for listing on the NRHP. If the project is
determined to have an effect on such properties, the agency must consult with SHPO and the
Advisory Council on Historic Preservation (ACHP) to develop alternatives or mitigation
measures. The project could likely be authorized by a letter of no effect, with SHPO's
concurrence.
• Water Quality Certification (CWA Section 401). Under CWA Section 401, applicants for a
Federal license or permit to conduct activities that may result in the discharge of a pollutant into
waters of the United States must obtain certification from the state in which the discharge would
originate. Therefore, all projects that have a federal component and may affect state water
quality (including projects that require federal agency approval, such as issuance of a Section
404 permit) must also comply with CWA Section 401.
Stormwater Discharge (CWA Section 402)
CWA Section 402 regulates construction -related stormwater discharges to surface waters through
the National Pollution Discharge Elimination System (NPDES) program, administered by the U.S.
Environmental Protection Agency (EPA). In California, the State Water Resources Control Board is
authorized by EPA to oversee the NPDES program through the Regional Water Quality Control
Lodi Lake Park North Side Restoration and 12 August 2015
Bank Stabilization Project Description ICF 00459.15
City of Lodi Parks, Recreation, and Cultural Services
Department
Boards (Regional Water Boards). The project area is located within the jurisdiction of the Central
Valley Regional Water Board.
NPDES permits are required for projects that disturb more than 1 acre of land. The NPDES
permitting process requires the applicant to file a public notice of intent (NOI) to discharge
stormwater, and to prepare and implement a stormwater pollution prevention plan (SWPPP). The
SWPPP includes a site map and a description of proposed construction activities. In addition, it
describes the best management practices (BMPs) that would be implemented to prevent soil erosion
and discharge of other construction -related pollutants (e.g., petroleum products, solvents, paints,
cement) that could contaminate nearby water resources. Permittees are required to conduct annual
monitoring and reporting to ensure that BMPs are correctly implemented and effective in
controlling the discharge of stormwater-related pollutants.
California Fish and Game Code (Section 1600, et seq.)
Under Sections 1600-1616 of the California Fish and Game Code, CDFW regulates activities that
would substantially divert, obstruct, or change the natural flow of a river, stream, or lake;
substantially change the bed, channel, or bank of a river, stream, or lake; or use material from a
streambed that falls under CDFW jurisdiction. In practice, CDFW marks its jurisdictional limit at the
top of the stream or lake bank, or the outer edge of the riparian vegetation, where present, and
sometimes defines its jurisdiction based on the levee crown within leveed river systems.
Notification is required prior to any such activities and CDFW will issue a streambed alteration
agreement with any necessary mitigation to ensure protection of the state's fish and wildlife
resources.
California Endangered Species Act of 1984
CDFW administers the California Endangered Species Act (CESA), which prohibits the take of listed
endangered and threatened species. Section 2090 of CESA requires state agencies to comply with
endangered species protection and recovery and to promote conservation of these species. CDFW
administers the act and authorizes take through Section 2081 incidental take agreements (except
for species designated as fully protected). It is assumed that this project would not require an
incidental take permit.
Central Valley Flood Protection Board Encroachment Permit
Pursuant to Title 23 of the California Water Code, the Central Valley Flood Protection Board (CVFPB)
(formerly The Reclamation Board) requires an encroachment permit for any non-federal activity
along or near federal flood damage reduction project levees and floodways or in CVFPB-designated
floodways to ensure that proposed local actions or projects do not impair the integrity of existing
flood damage reduction systems to withstand flood conditions. If applicable, the permit is
conditioned upon receipt of permission from USACE for alteration of the federal project works
pursuant to U.S. Code Section 408. The entirety of Lodi Lake Park lies within the CVFPB-designated
floodway, so consultation with the CFVPB would be necessary. However, because the lower
Mokelumne River is not protected by federal levees, the CVFPB has confirmed that compliance with
Section 408 would not be necessary for this project, and a "non -fed" letter would be issued by the
USACE (Buckley pers. comm.).

City of Lodi Parks, Recreation, and Cultural Services
Department
California Environmental Quality Act
Acquisition of any state permits (e.g., Section 1600 Streambed Alteration Agreements, Section 2081
Agreements) trigger compliance with the California Environmental Quality Act (CEQA). The project
may qualify to be exempt from CEQA under a categorical exemption. Potential applicable categorical
exemptions could be Class 1, for existing facilities; Class 2, for replacement or reconstruction of
existing structures and facilities; or Class 33, for small habitat restoration. If the project is not found
exempt under CEQA, an initial study will be prepared.
Community Outreach
In the winter and spring of 2015, the City conducted a Community Interest and Opinion Survey to
help determine parks, recreation, and cultural priorities for the community. The City used the
results of the survey to directly inform the elements of the proposed project. Through the survey,
the community voiced a strong desire for the City to upgrade Lodi Lake facilities and amenities, to
build additional walking trails, and to connect existing trails. Indeed, respondents ranked "upgrade
Lodi Lake facilities and amenities" as the most important action the City could take (83% of
respondents ranked this action as "very important" or "somewhat important"), followed closely by
"build additional walking & biking trails & connect existing trails" (82% of respondents ranked this
action as "very important" or "somewhat important") (ETC Institute, 2015).
The City has already embarked upon outreach efforts to familiarize stakeholders and park visitors
with the park's erosion problems and to garner interest in the proposed project. The following
actions have been taken.
• Conceptual drawings illustrating the future planted condition of the shoreline and location of
the proposed path were presented at the City's Parks and Recreation Commission meeting on
August 4, 2015.
• Jeff Hood, the Director of the City of Lodi Parks, Recreation, and Cultural Services Department
appeared on a KCRA Channel 3 news segment on August 10, 2015 to discuss the park's erosion
issues and this proposed project, and again on KXTL Channel 40 news segments on August 25,
2015.
• The Park Superintendent has posted temporary fencing and signs along the eroded areas
stating: "Ecosystem Restoration and Bank Stabilization Project; Area Closed to the Public; LMC
12.12.050." The City posted an entry about the fencing on the Lodi Parks, Recreation, and
Cultural Services blog (http://Iodipres.blogspot.com/) on August 17, 2015. Through comments
on the post, community members have voiced their support for the project.
• A joint "shirtsleeve" (no voting action) session of the Lodi City Council and Parks and Recreation
Commission was held on August 25, 2015 at Lodi Lake Park to provide Council and Commission
members with an up -close view of the erosion and to provide the public with a chance to
comment on the conceptual design.

Cost -Share Opportunities
In order to show their commitment to this project, the City may pursue in-kind and monetary cost -
share opportunities to help fund the project. Some of the applicable options are described below.
City Staff Labor
The City may choose to donate the time of its employees as an in-kind cost share. The type of work
conducted by the City may include: project planning and project management; drafting and
submission of permit applications; public outreach; irrigation system remediation; base map
acquisition; and construction oversight.
Lower Mokelumne River Partnership
The Lower Mokelumne River Partnership, is a joint effort led by EBMUD, USFWS, and CDFW. They
have in the past shown interest in funding planting activities and may be a source of matching funds
for native plant procurement or installation.
Volunteerism and Donations
The City of Lodi boasts an active and interested community of volunteers who provide docent
services and assist with planting projects. Groups who have volunteered at Lodi parks in the past six
months include Tree Lodi, Rotary clubs, the Lions Club, the Kiwanis Club, the Boy Scouts of America,
Tokay and Lodi High Schools' environmental clubs, Mormon Helping Hands, the local First Baptist
Church, and other church groups. Volunteers from the community and volunteer groups can provide
an important source of labor for project implementation. Often the costs of material installation is
half to two-thirds labor. The value of volunteer labor, especially labor that is organized and skilled, is
enormous. Trail installation, planting, irrigation system retrofitting, and some site repair work are
examples of potential volunteer projects.
Materials donated to project implementation by local businesses or community organizations can
help offset project implementation costs. Large donations can be recognized through special signage
or plaques at the project site acknowledging the gift.
By having community involvement through volunteer projects and investment, the value of the
labor and services makes available funding stretch further and can give the community a greater
sense of ownership and pride in the project. Fostering community ownership of the project,
especially by younger members of the community, will give the project a better chance to receive
community support and monitoring by the public.
Partnerships with Other Organizations
The City could partner with other local organizations who might share common goals or values as a
way to further connect with the community, raise awareness, and leverage in-kind services. The City
of Lodi is a partner with the Lower Mokelumne River Watershed Stewardship Steering Committee
(Committee) on this project. The committee operates under the auspices of the San Joaquin County
Resource Conservation District (SJCRCD). Since 2000, SJCRCD has received grants to employ a
watershed coordinator for the lower Mokelumne River watershed, and the coordinator is a partner
with the City on education and outreach activities related to the Mokelumne River. The City and
SJCRCD have a successful history of partnership on two grants (one completed, the other underway)
Lodi Lake Park North Side Restoration and August 2015

to conduct education and outreach activities for both adults and school students focused on the
lower Mokelumne River.
Other potential partners in the area include, but are not limited to:
