1.0 SUMMARY
1.1 Summary
Olberding Environmental, Inc. (Olberding Environmental) has prepared this Mitigation
Monitoring Plan (MMP) on behalf of North Valley Towing (Applicant/Permittee) to provide
compensatory mitigation for impacts to jurisdictional wetland/waters of the U.S. resulting from
the development of the Hicks Lane Project (Project) outside the City of Chico, Butte County
California. Mitigation for impacts specific to the Project will be provided onsite with the creation
of 0.26 acre of constructed wetlands. The Project and the planned mitigation will occur on the
property located approximately 1.1 miles southwest of the Chico Municipal Airport, on Hicks
Lane, Butte County, California, APN 007-010-054 (Property).
The proposed Project involves the placement of permanent fill of a U.S. Army Corps of Engineers
(Corps) Section 404 jurisdictional wetlands. As a result of the development of the Property,
permanent impacts to Corps jurisdictional features will result in a total of 0.13-acre and include
the placement of 210 cubic yards (cuyd) of redistributed clean earthen fill. Onsite mitigation will
result in the creation of onsite seasonal wetland features at a 2:1 ratio.
Compensatory mitigation for impacts to 0.13-acre of jurisdictional wetlands will be provided
onsite with the creation of approximately 0.26 acre of seasonal wetlands. This MMP includes
summary information about the compensatory mitigation area; objectives for the compensatory
replacement and implementation specifications (including underlying rationale for expecting
success); maintenance and monitoring provisions; and contingency measures.
This MMP is subject to approval by federal and state regulatory agencies, which includes the
Corps, the California Department of Fish and Wildlife (CDFW), and the California Regional Water
Quality Control Board (RWQCB).

o Maintaining and replacing signs and other infrastructure, as needed.
o Collecting and removing trash.
o Preparing and submitting annual reports.
The Land Manager under this MMP is appointed by the Applicant/Permittee and would remain in
that designated role unless and until replacement by another well-qualified consultant that would
be responsible for the specified land management responsibilities.
1.2.3 Project Biologist
The Applicant/Permittee shall implement this MMP for biological impacts and manage and
monitor the mitigation program in accordance with this MMP.
The Permittee is responsible for hiring a Project Biologist to monitor habitat on the impact and
compensatory mitigation site. The Project Biologist will be a professional botanist, biologist, or
restoration ecologist familiar with California flora and fauna and will have a working knowledge
regarding protected habitats and species as defined by the resource agencies. The Project Biologist
must also be familiar with vegetation management practices for maintaining the created habitats.
1.2.4 Deed Restriction
A deed restriction will be placed on the mitigation habitat to ensure that the habitat and wildlife
values will be retained forever and prevent any use of the Property that would impair or interfere
with the conservation values of the covered area. The Permittee will be required to record the deed
restriction in the Butte County Recorder’s Office.
1.3 Project Description
The Applicant is undertaking development of an approximately 12.1-acre parcel of property
(Property) located outside the city limits of Chico, California. The proposed development plans
(Project) include the construction of a gravel driveway, parking area, and storage yard, a small
(30’ x 56’) office building, a solar array, a portable toilet, and a storm drain detention and treatment
basin. All construction will take place in the northwest portion of the Property, designed to avoid
impacts to the seasonal wetland and ephemeral drainage features identified on the Property. Project
impacts have been minimized to approximately 0.13 acre of seasonal wetland swales. The Project
Site Plan has been included as Attachment 2.
The inclusion of construction measures will help avoid and minimize additional project impacts.
Orange construction fencing would define the work area and provide a buffer for any seasonal
wetlands and ephemeral drainages that are protected outside of the proposed area of affect. Erosion
and siltation controls will be used and maintained during and after construction to prevent
sediments from entering adjacent unimpacted drainages on the Project site. To further mitigate
Hicks Lane Property Mitigation Monitoring Plan

project impacts, the creation of 0-26-acre of seasonal wetlands will occur at a 2:1 ratio.
1.3.1 Project Site Location
The Property is located approximately 1.1 miles southwest of the Chico Municipal Airport, on
Hicks Lane in Butte County, California. The Property itself lies just outside the City limits of
Chico. Attachment 1, Figure 1 depicts the regional location of the Property in Butte County and
illustrates the vicinity of the Property in relationship to the City of Chico. Attachment 1, Figure 2
illustrates the vicinity of the Property in relationship to the City of Chico. Attachment 1, Figure 3
identifies the location of the Property on the USGS 7.5 Quadrangle Map for Richardson Springs.
An aerial photograph of the Property has been included as Attachment 1, Figure 4.
Access to the Property is provided from Highway 99. From Chico, take Highway 99 North for
approximately 3.7 miles, then take exit 389 for Eaton Road. After exiting, turn right onto Eaton
Road and travel for approximately 125 feet before turning left onto Hicks Lane. The Property will
be on the right side after approximately 0.9 miles.
1.3.2 Project Site Description
The Project consists of Butte County Assessor Parcel Number (APN) 007-010-054 and
encompasses approximately 12.1 acres in a rectangular shape bounded on the north and east by
open space, residential development to the west, and a small ranchette to the south. The Property
supports four habitat types consisting of annual grassland, seasonal wetland, seasonal swale, vernal
pools and ephemeral drainage (Attachment 1, Figure 7). Characteristic vegetation within the
ruderal grassland includes medusa head (Taeniatherum caput-medusae), Italian ryegrass (Festuca
perennis), turkey mullein (Croton setiger), prickly lettuce (Lactuca serriola), and vinegarweed
(Trichostema lanceolatum). The southern boundary of the Property is lined with eucalyptus
(Eucalyptus sp.) trees and cultivars of various ornamental species.
Two ephemeral drainages occur on the Property. The first drainage consists of a large, cobble-
lined channel that flows across the northwestern corner of the Property and occupies 0.01 acres or
280 LNFT. This channel is fed by two culverts on the northern edge of the Property and exits the
western side of the Property via a box culvert below Hicks Lane. The second drainage is also
cobble-lined and flows along the southern boundary of the Property and occupies 0.02 acres or
330 LNFT.
The Property also contains two seasonal wetlands. The first wetland is the largest at 2.75 acres and
extends across the majority of the eastern and southern portions of the Property. This wetland is
best described as a complex of vernal pools and swales that flow between and around shallow
upland mounds. This feature intercepts sheet-flow runoff via a culvert present along the northern

boundary of the Property. The second seasonal wetland immediately surrounds the second
drainage in the northwestern corner of the Property and occupies 0.13 acres. Additionally, two
seasonal swales are present in the northwestern portion of the Property; these features occupy 0.13-
acre.
The topography of the Property consists of relatively flat land broken by mound-intermound relief,
primarily in the eastern half of the site. Elevation ranges between 187 feet above sea level in the
southwestern corner of the Property and 193 feet above sea level in the northeastern corner.
1.3.3 Permanent Impacts to Protected Resources
An Aquatic Resources Delineation was conducted by Olberding Environmental, Inc. in November
of 2019. The results of this preliminary aquatic delineation determination (letter dated May 20,
2020) indicate the extent of jurisdictional wetlands/waters of the United States (U.S.) occurring on
the Project site. The Impacts Map (Attachment 1, Figure 5) identifies the presence of
approximately 2.60 acres of seasonal wetlands, and 0.13 acre of seasonal wetland swales on the
Property. Of the existing habitat, approximately 0.13 acre of seasonal wetland swales will be
impacted by Project activities. Table 1 shows the summary of impacts by acreage to existing
wetlands and the compensatory mitigation required.
A Biological Resources Analysis for the Project site was prepared by Olberding Environmental in
November 2019.
The currently proposed development activities will permanently impact approximately 0.13-acre
of seasonal wetland swale habitat (Figure 5). The required compensation ratio for these impacts
was determined to be 2:1 for creation.
2.0 OBJECTIVES
The primary objective is to provide compensatory mitigation for unavoidable impacts to 0.13-acre
of wetland swale habitat through the establishment of 0.26-acre of compensatory wetlands, along
with the preservation of onsite ephemeral drainages, seasonal wetlands, and vernal pools. A
summary of mitigation activities is included below in Table 1.

2.2 Habitat Establishment (Creation)
Establishment (creation) means the manipulation of the physical, chemical, or biological
characteristics present to develop a natural resource that did not previously exist at an upland site.
Establishment of habitat results in a gain in natural resource area and functions.
The Applicant/Permittee proposes the creation of 0.26-acre of seasonal wetland habitat
(Attachment 1, Figure 5). This will meet the mitigation requirement of 2:1 for creation of wetland
features.

3.0 PROPERTY BASELINE INFORMATION
3.1 Watershed Description
The Property is located within the Mud Creek watershed 10-digit hydrologic unit code (HUC
1802015706). This approximate 81,099-acre HUC runs from the Sacramento River northeast into
the Sierra Nevada and includes the north half of the City of Chico. The watershed is bound by Big
Chico Creek to the south and east, Jewett Creek-Sacramento River watershed to the west, and the
Pine Creek watershed to the north. The Property is located approximately 0.25 mile north of
Sycamore Creek and just over 0.6-mile northeast of the confluence of Sycamore Creek and Mud
Creek.
3.2 Climate and Precipitation
The Central Valley of California is characterized by a Mediterranean climate of hot, dry summers
and generally mild, wet winters. In a typical year, two thirds of the precipitation falls during the
“rainy season” of November through February. Several mountain ranges surround the Valley on
all sides, which has a significant effect on precipitation and wind patterns throughout the Valley.
The annual average rainfall for the Chico Area is 25.84 inches. While historically there have been
several snow events reported in the area, the vast majority of the precipitation falls as rain. Mean
maximum temperatures range from a low of 35 degrees Fahrenheit in December and January and
a high of over 96 degrees Fahrenheit in July (NOAA 2022).

3.3 Soils
The USDA Natural Resources Conservation Service (NRCS) mapped two soil types within the
Preserve (NRCS 2022). A detailed map of the soils for the Survey Area can be found in Attachment
1, Figure 6. The soil types mapped on the Property include the following types (USGS 2006):
• 302: Redtough-Redswale, 0% to 2% slopes – The Redtough-Redswale series is found
on mounds and high fan terraces. This series typically consists of 50% Redtough loam,
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
13
35% Redswale cobbly loam, and 15% minor components. Both the Redtough and
Redswale soils conisist of shallow to very shallow, poorly drained soils that formed in
alluvium derived from dominantly volcanic rocks. Runoff potential for this soil series is
very high.
• 336: Galt clay, 0% to 1% slopes – The Galt clay series is found in basins,
drainageways, and swales on low terraces. This series typically consists of 90% Galt
clay and 10% minor components. This series consists of moderately deep, poorly drained
soils that formed in alluvium derived from mixed rock sources. The runoff potential for
this soil series is high.
While the Redtough-Redswale soil series is not listed as hydric, the Galt clay series is. Hydric soils
are defined by the National Technical Committee for Hydric Soils as soils that formed under
conditions of saturation, flooding, or ponding long enough during the growing season to develop
anoxic conditions in the upper part.
3.4 Vegetation
The Property supports four habitat types consisting of ruderal grassland, seasonal swale, seasonal
wetland, and ephemeral drainage. In classifying the habitat types on the site, generalized plant
community classification schemes were used (Sawyer, Keeler-Wolf, and Evens 2009). The final
classification and characterization of the Project site's habitat type was based on field observations.
The habitat types and a description of the plant species present within each habitat type are
provided below. Dominant plant species are noted. The site habitats are shown on Attachment 1,
Figure 7.
3.4.1 Ruderal Grassland
A large majority of the Property is dominated by ruderal grassland habitat. Dominant vegetation
observed within this habitat type includes but is not limited to medusa head, Italian ryegrass, turkey
mullein, Palmer's amaranth (Amaranthus palmeri), tumbleweed (Amaranthus albus), prickly
lettuce, and vinegarweed.
3.4.2 Seasonal Swale
The vegetation within the seasonal swales was consistent with the surrounding uplands. These
features did not contain a defined channel, nor did they show any of the three criteria required to
be considered a wetland. Instead, they can be described as low-spots or depressional basins relative
to the surrounding upland mounds.
Hicks Lane Property Mitigation Monitoring Plan

3.4.3 Seasonal Wetland
There are two seasonal wetlands found within the Property. The ephemeral drainage in the
northwestern corner of the Property is embedded within a larger seasonal wetland and is
characterized by hydrophytic plants such as curly dock (Rumex crispus), Italian ryegrass, and Great
Valley button celery (Eryngium castrense).
The largest wetland feature is a large mosaic of upland mounds and swale- and vernal pool-like
wetlands, many of which contained cobble or bare ground as the dominant cover. Vegetation
within the fringes of this feature was consistent with the surrounding grasslands. Vegetation within
the wetland basins consisted of wetland species such as Great Valley button celery, goldfields
(Lasthenia californica), rosy Douglas’ meadowfoam (Limnanthes douglasii ssp. rosea), curly
dock, annual hairgrass (Deschampsia danthonioides), and California amaranth (Amaranthus
californicus). In some areas, upland vegetation such as medusa head was the dominant cover; the
vernal nature of the wetlands and short hydroperiod allows for upland vegetation to establish once
the wetland dries. Ground cover within the wetland also included the presence of biotic crusts,
which is recognized by the Corps as a primary hydrologic indicator. Plant species such as button
celery, goldfields, and meadowfoam primarily occur within vernal pool systems, and their
presence within the seasonal wetlands are a strong indicator that at least portions of the features
can be classified as vernal pools.
3.4.4 Ephemeral Drainage
The Property contains two ephemeral drainage features. Vegetation within the feature in the
northwest corner of the Property was primarily comprised of rocks and cobble, but several species
such as spikeweed (Centromadia fitchii), curly dock, Italian ryegrass, Great Valley button celery,
and European heliotrope (Heliotropium europaeum) were found in the channel. Ground cover
within the feature also included biotic crusts. Additional indicators of hydrology include drainage
patterns and oxidized rhizospheres among living roots.
Cover within the southern drainage was mostly cobble, but surrounding vegetation was consistent
with the ruderal grassland. Ground cover within this feature also included biotic crusts.
3.5 Wetlands/Waters of the U.S.
Hydrologic characteristics, flow, and connectivity were determined in 2019 during a wetland
delineation following Corps standard protocol within the Property. The delineation was verified
by the Corps on May 22, 2020 (SPK-2019-00055) and included the presence of 2.89 acres of
seasonal wetlands, 0.07-acre (1,524 linear feet) of ephemeral drainage, and 0.13 acre of non-
jurisdictional seasonal swales within the area surveyed. However, the Property boundary for this
MMP has been modified from the 2019 delineation survey area. As is shown in Attachment 1,
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
15
Figure 5, there are 2.6 acres of seasonal wetlands, 0.13-acre of seasonal swales, and 0.03-acre (610
linear feet) of ephemeral drainage within the Property boundary.
3.6 Special-Status Species
A list of potential special-status species occurring on the Property were compiled from the
CNDDB (CDFW 2022), the California Native Plant Society (CNPS 2022), and the USFWS
(USFWS 2022). A list of species that were observed on the Property can be found within
Attachment 4.
3.6.1 Special-Status Plant Species
A preliminary review of biological resources for the Property conducted by Olberding
Environmental in 2019 found that the Property has the potential to support numerous special status
plant and wildlife species. A summary of the results of the determination for special status species
is provided below. Figures 8 and 9 show the CNDDB results for a five-mile radius around the
Project site for special-status plants and wildlife.
Based on a California Natural Diversity Database (CNDDB) search for special-status plant species,
two plants have the potential to occur on the Property (CDFW 2022). These species include the
adobe lily (Fritillaria pluriflora) and Butte County meadowfoam (Limnanthes floccosa ssp.
californica). Suitable habitats for both these plant species occur throughout the Property within
the grassland, seasonal wetland, and swale habitats.
3.6.2 Special-Status Wildlife Species
Numerous special status wildlife species were determined to have a potential to occur on the
Preserve. These species are discussed below.
Invertebrates – Three invertebrate species, California linderiella (Linderiella occidentalis),
vernal pool tadpole shrimp (Lepidurus packardi), and vernal pool fairy shrimp (Branchinecta
lynchi), have been identified as having a high potential to occur on the Property. Multiple CNDDB
occurrences and USFWS designated critical habitat of vernal pool fairy and tadpole shrimp are
recorded in the vicinity of the Property. The Property contains suitable habitat in the seasonal
wetlands, especially the large vernal pool complex in the eastern portion of the Property.
Amphibians – It was determined that there is no potential for any special-status amphibians to
occur on the Property.
Reptiles – It was determined that there is no potential for any special-status reptiles to occur on
the Property.
Hicks Lane Property Mitigation Monitoring Plan

Birds – A total of six bird species were identified as having potential to occur on the Property.
Five species including red-shouldered hawk, red-tailed hawk, white-tailed kite, American kestrel
and Cooper’s hawk have a high potential to occur in a foraging and/or nesting capacity. Swainson’s
hawk had a moderate potential to utilize the open grassland habitats in a foraging capacity. A red-
tailed hawk and American kestrel were observed foraging on the Property during surveys.
Mammals – Given the presence of suitable onsite habitat; the pallid bat and hoary bat have a
moderate potential to occur on the Property in a foraging and/or roosting capacity. No immediate
signs were present during the initial survey, but the large eucalyptus trees along the southern
Property boundary could provide suitable roosting habitat.

4.0 IMPLEMENTATION PLAN
This section presents the Implementation Plan for the mitigation habitat. Wetland habitat creation
(establishment) will include the creation of new depressional features to develop into seasonal
wetland habitat, followed by revegetation with a native grass and wildflower seed mix.
4.1 Implementation Approach and Sequence
This section summarizes wetlands creation activities and sequencing and identifies the
responsibilities of the Project Biologist and Restoration Contractor. The Mitigation Plan shows the
areas where wetland creation will occur within the Project site (Attachment 1, Figure 6). As-built
plan survey activities and reporting will also be conducted at the completion of work.
4.2 Site Preparation
The wetland establishment site will first be mowed close to the ground and the upper 4 to 6 inches
of soil will be excavated and stockpiled at designated upland locations.
4.3 Grading
The created seasonal wetlands will be graded/excavated using a rubber-tired earth mover to form
bottom microtopography and side slopes. Excavated material will be temporarily stockpiled onsite
and will be mounded as a balanced cut-and-fill project.
Finish grading will involve grading along the edges of an excavated area to tie into existing
topography and grading the bottom of the created wetland area to provide the appropriate flat
topographic relief (<1-2 percent slope) for wetland hydrology, soil, and plant development.
Grading activities will be monitored by a grade checker using a hand level to ensure that the
constructed wetlands meet the design criteria. The grade checker will be under the direction of the
Project Biologist.
4.4 Erosion Control
To prevent erosion and siltation from occurring, all exposed soils will be permanently stabilized
following construction.
Erosion-control fabric mats (consisting of straw coconut fiber) should be installed according to the
manufacturer’s recommendations on the disturbed area of the berm. The erosion control fabric
cannot contain any mono-filament plastic, as this slow-to -degrade plastic netting may entangle,
injure or kill wildlife. Straw wattles and erosion control fabric will be used around all edges of the
Project site that are downslope of construction where mobilized particles have a direct path to
water bodies. The contractor shall implement BMP measures around all work areas so that any
erosion will not impact any water features or surrounding protected areas. Soil stabilization shall
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
18
be used to prevent the initial mobilization of soil particles during a rain event. The most efficient
way to address erosion control is to preserve existing vegetation where feasible, to limit
disturbances, and to stabilize and revegetate disturbed areas as soon as possible after grading or
construction operations have been completed.
4.5 Revegetation of Disturbed Areas
The created wetland will be seeded with a native seed mix to enhance wetland vegetation growth.
Seeding with native seed mix (Table 4), coupled with natural colonization by species from seed
sources in the existing soils and dispersal from adjacent habitats will bring in a mix of both native
and non-native species. The established wetlands are expected to show significant vegetative
growth within 3 to 4 years.
Species selected for the wetland and upland seed mixes were chosen based on their respective
wetland indicator statuses and the ability to survive in alkaline/saline environments. To ensure
suitability to the conditions at the Project site, many of the species chosen for both the wetland and
upland seed mixes have a moderate to high salt tolerance.
Hydrophytic plant species, or those with an indicator status of FAC, FACW, or OBL, were chosen
for the wetland seed mix as they are more suited to frequent saturation and/or inundation. Most of
the species selected for the upland seed mix have a wetland indicator status of FAC, FACU, or
UPL as they are more suited to dry conditions.
The areas to be seeded will be harrowed after finish grading to achieve a one to two-inch deep
friable seed bed. The seed mix will be broadcast at the specified rates and lightly harrowed into
the seed bed to achieve good seed to soil contact. Any erosion control BMPs including fabric and
straw wattle installation will occur after broadcast of seed but before application of hydromulch.
A mixture of hydromulch, tackifier, and water at appropriate rates will be sprayed with a trailer or
truck-mounted hydroseeder over the top of the seeded soil bed. Seeding is planned to occur right
before the rainy season (i.e., September/October) or early on in the rainy season (i.e., November).
It is anticipated that wetland plant species will colonize rapidly during the winter/spring following
construction.

4.6 Implementation Schedule
Construction of the mitigation habitat is planned for 2022 depending on receipt of permits and
authorizations. Because the established wetlands will not receive supplemental irrigation water,
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
20
the seeding timing is important. Due to the unpredictability of the rainy season, the Project
Biologist will schedule the seeding. After initial seeding is complete, the site will be maintained
and managed by activities described in this MMP.
4.7 Documentation of As-Built Conditions
Within 60-days after riparian enhancement construction is complete; a post-construction as-built
survey will be prepared and submitted to Corps. This report will include:
• The as-built plan based on the post-construction survey.
• Description of construction activities, with emphasis on any last-minute adjustments to the
installation plan based on existing field conditions.
• Photo-documentation of construction activities, as well as identification of permanent
photo point locations.

5.0 SITE PROTECTION INSTRUMENT
A deed restriction will be placed on the mitigation habitat that will ensure the ecological functions
and values of the mitigation habitat. The deed restriction will be recorded with Butte County and
will prohibit development or any other activities from occurring within the deed-restricted area.
The deed restriction will prohibit the following activities from occurring within the mitigation
habitat:
a) Unseasonal watering, use of fertilizers, pesticides, biocides, herbicides, or other
agricultural chemicals, that may adversely affect the ecological functions and values of the
mitigation habitat,
b) Depositing or allowing the uncontained accumulation of trash, ashes, garbage, waste, or
any similar other material,
c) Removing, destroying, or cutting of native trees, native shrubs, or other native vegetation,
except as required for the prevention or treatment of disease, abatement of weeds or
invasive plants, fire protection and implementation of this MMP. However, no removal of
living native shrubs or trees is allowed for any reason,
d) Introduction of non-native, exotic, or invasive species,
e) Use of vehicles off designated roadways unless necessary to implement this MMP or for
emergency fire management or personal safety,
f) Paving or otherwise covering of the mitigation habitat with concrete, asphalt, or any other
impervious paving material,
g) Filling, dumping, excavating, draining, dredging, mining, or drilling,
h) Removing or exploring for or extraction of minerals, loam, sands, gravel, or other material
on or below the surface,
i) Altering the surface or general topography, including building of roads, or construction of
temporary or permanent structures, except as necessary for maintenance or restoration of
the mitigation habitat.
6.0 PERFORMANCE STANDARDS
This section presents the performance standards that need to be achieved before the compensatory
mitigation activities can be deemed successful. Annual monitoring results will be compared with
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
22
performance standards to indicate the extent to which the mitigation area is developing suitable
wetland habitat. If annual monitoring results fall below performance standards, the cause will be
investigated by the Project Biologist and adaptive management recommendations will be proposed
to remediate the deficit and attain compliance with the final performance standards.
Wetland habitats at the Preserve will be monitored and the results will be compared against
performance standards to ensure the site provides high quality ecological functions and values.
There will be five performance standards (PS) for the mitigation habitats areas as follows:
• PS1 – The established (created) wetlands will exhibit USDA NRCS hydric soil
characteristics appropriate for the region by Year 5.
• PS2 - The frequency of inundation and/or saturation will be a minimum of 18.25
continuous days per year within the established (created) wetlands.
• PS3 – The established (created) wetlands will show 40 percent overall vegetative cover by
Year 1, 65 percent cover by Year 3, and 80 percent overall vegetative cover by Year 5.
• PS4 – The established (created) wetlands will show at least 30 percent wetland vegetation
(OBL, FACW, FAC) cover by Year 3, and 51 percent by Year 5.
• PS5 – Nuisance plant species cover on the overall site will not be greater than 5 percent.
Nuisance plant species will be those that have a “high” or “red alert” rating by Cal-IPC or
are “moderate” broadleaf species based on their invasive ranking.
7.0 MONITORING AND REPORTING
Monitoring and reporting for performance will occur for a minimum of 5-years for wetlands/waters
or until attainment of performance standards. If performance standards are not met by the end of
the stated monitoring and management period for a given habitat type, then monitoring can be
extended into future years until performance standards are attained, remedial actions may occur,
or compensatory mitigation may be required through another mitigation mechanism to make up
the difference.
The monitoring objectives:
1. Track habitat progress towards meeting the performance standards, and
2. Identify and remedy any problems that could impact the success of the mitigation effort
and/or compromise the ecological functions and values of the site.
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
23
The monitoring protocol and results will be reviewed annually. Adjustments to monitoring
procedures may be required as the site changes over time, or if logistical problems render a
procedure unduly difficult to conduct. Such adjustments will be discussed with the regulatory
agencies as necessary. After reviewing the monitoring reports, the regulatory agencies may also
have suggestions for adjusting the monitoring program. Regulatory agency suggestions will be
reviewed and, if appropriate, incorporated into the following year's monitoring program. The key
is to anticipate that the monitoring program may need occasional adjustments to remain accurate,
complete, and feasible.
7.1 Wetland Establishment
Hydrology data will be collected from the established (created) wetland habitat to coincide with
the California rainy season (i.e., Sept/Oct to Apr/May). The first hydrology data collection event
will occur with the onset of fall rains no more than two weeks after the first soaking rain event
(i.e., one inch of rain within a 24-hour time periods). Wetland hydrology monitoring will occur at
least monthly during the rainy season and will not end until bankfull ponding is documented with
a photograph and/or at least 18.25 days of ponding/saturation has occurred. Monthly hydrology
monitoring events will occur until the seasonal wetlands are totally dry, presumably by early- or
mid-summer.
Monitoring of seasonal wetland vegetation using randomly placed one square meter quadrats will
occur during the spring monitoring event. The number of necessary quadrats will be determined
during the first monitoring visit. Determining the number of quadrats will involve counting the
number of plant species found within four randomly placed quadrats within the created wetland.
A species-area curve will be created to show the relationship between number of species and
number of quadrats. At the point of inflection on the curve (where the number of species is no
longer increasing) is the number of quadrats that should be used.
Once an appropriate number has been determined, quadrats will be randomly located along
perpendicular transects extended through the length and width of the seasonal wetland habitat.
Each plant species occurring within the quadrat will be recorded and assigned an absolute cover
value. The absolute percent cover of bare ground and thatch will also be recorded from each
quadrat. Photos will be taken of the quadrats and a representative sample will be included in annual
monitoring reports.
Photographic monitoring will also occur at each wetland data collection event from fixed photo
points and any other relevant areas. Photos of actively ponded wetlands will be taken and provided
in monitoring reports.
Annual precipitation data will be obtained from the closest climatological station and included in
monitoring reports.
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022

Vegetation, soil, and hydrologic conditions will be monitored using the Corps’ 1987 Wetlands
Delineation Manual, the Corps’ September 2008 Regional Supplement to Corps of Engineers
Wetland Delineation Manual: Arid West (Version 2.0) (Arid West Supplement), and relevant
Corps guidance documents whereby field observations will be made in the wetlands during the
rainy season until the wetland soil and hydrology criteria are met. The percentage and depth of
ponded water and/or soil saturation will be noted during monitoring visits. This information will
be recorded on the Arid West field data sheet.
7.2 Non-Native Invasive Vegetation Monitoring
Plant species designated by the California Invasive Plant Council (Cal-IPC 2022) to be plant pests
(impact rating of “high” or included as “red alert”) and species rated “high priority” by the Bay
Area Early Detection Network will not be allowed to colonize and become established within the
mitigation habitat. The percent cover of non-native invasive species will come from qualitative
and quantitative plant community assessment, wetland delineation vegetative data, direct
observation, and/or photo documentation. Ocular estimations of overall vegetation cover, density,
and frequency will be used to ensure that non-native invasive vegetation is kept below a total of 5
percent cover across the Preserve. Any problematic or new stands of non-native invasive
vegetation will be photographed and described in the monitoring report along with
recommendations for control and/or eradication.
7.3 Photo Documentation
Photo documentation will occur during all monitoring years from permanent photo stations that
will be established during construction and shown on the as-built plan drawings. Photo station
locations will be selected to illustrate year-to-year progress in relation to the existing habitat. Photo
locations will be recorded with GPS equipment to ensure photos will be taken from the same
location each year. Photographs will also be taken to record any events that may have a significant
effect on the success of restoration, such as flood, fire, or vandalism. The location and direction of
view of the photo stations will be provided with all monitoring reports. Color photocopies of the
permanent photo stations will be included as an attachment in monitoring reports.
7.4 Annual Report
Habitat establishment monitoring reports summarizing the results of the monitoring effort will be
submitted to the regulatory agencies by December 31 every year for the first 5 years.
The annual report will document the degree to which the mitigation habitat is meeting the
performance standards. The monitoring reports will describe any deficiencies in attaining and
maintaining performance standards and any remedial action proposed, approved, or performed. If
Hicks Lane Property Mitigation Monitoring Plan
_____________________________________________________________________________________________
Olberding Environmental August 2022
25
remedial action(s) have been completed, the annual report will also evaluate the effectiveness of
that action.
A final monitoring report summarizing the mitigation project and evaluating the site's overall
performance will be prepared and submitted at the end of monitoring (Year 5). The final annual
report will include a count and assessment of species. A final field visit will be conducted to verify
that onsite conditions are consistent with information documented in the annual reports.
The annual report will include the following information.
1.0 Project Overview (1 page)
a. Agency Permit Numbers
b. Name of party responsible for conducting the monitoring and the date(s) the

8.0 ADAPTIVE MANAGEMENT/REMEDIAL MEASURES
Adaptive management is a strategy to deal with unexpected changes in site conditions,
responsibilities, or performance of the site so that the compensatory mitigation project achieves its
objectives and ecological performance standards.
Potential problems that may trigger a need for adaptive management include failure to attain
performance standards, fire, substantial infestation by non-native plants and animals, and
unanticipated anthropogenic problems such as large-scale trespassing and vandalism.
The Project Biologist will regularly analyze site progress as part of monitoring and reporting and
will suggest remedial measures to address unforeseen changes in site conditions or other
components of the mitigation project.
If the annual monitoring results indicate that the site is falling below performance threshold values,
then remedial actions will be implemented and funded by the Permittee of the mitigation project.
Remedial actions may include but are not limited to: wetland reconstruction, reseeding, nuisance
plant control and eradication, monitoring for additional years, and mitigating for the project at an
alternative site.
A variety of natural, design or construction variables can affect the rate at which habitats establish.
Mitigation habitats that have not started trending towards achieving performance standards within
the first year or two of construction may still function and may still achieve the performance
standards at a later point in the 5-year habitat establishment period.
In the event that the mitigation is not trending towards meeting performance standards, yet
progressive improvement in site conditions is evident, the Land Owner will evaluate whether to
remediate or request an extension of the establishment period. In the event that a design or
construction flaw has rendered remedial actions necessary, the Land Owner will work with the
Land Manager and the Resource Agencies as necessary to discuss remedial actions.
In the event that the wetland is not meeting hydrology performance standards, investigation will
be conducted to determine if the wetland is too shallow. If possible, the wetland will be deepened
to increase ponding, a replacement site may be identified, or another wetland may be expanded.
This type of remediation would require approval from the Resource Agencies.
In the event that the wetland is not meeting floristic performance standards, the hydrology would
be checked, and additional seeding may be performed. Alternative wetland mitigation sites may
be required if the wetland mitigation activities are deemed unsuccessful following any identified
or augmented monitoring period.
Hicks Lane Property Mitigation Monitoring Plan

In the event that the need for remedial actions is identified, the Land Owner and Land Manager
will work with the Resource Agencies on developing remedial actions that meet consensus
approval. Remedial actions will only begin after all the Resource Agencies have agreed on the
remedial action.
