Required Mitigation and Monitoring Programs
Air Quality
AQ-1 Idling Control Techniques. During all construction activities and use of diesel vehicles, the
applicant shall implement the following idling control techniques:
1. Idling Restrictions Near Sensitive Receptors for Both On- and Off-Road Equipment.
a. Staging and queuing areas shall not be located within 1,000 feet of sensitive
receptors if feasible;
b. Diesel idling within 1,000 feet of sensitive receptors shall not be permitted;
c. Use of alternative-fueled equipment shall be used whenever possible; and
d. Signs that specify the no idling requirements shall be posted and enforced at
the construction site.
2. California Diesel Idling Regulations. On-road diesel vehicles shall comply with 13
CCR 2485. This regulation limits idling from diesel-fueled commercial motor
vehicles with gross vehicular weight ratings of more than 10,000 pounds and licensed
for operation on highways. It applies to California- and non-California-based
vehicles. In general, the regulation specifies that drivers of said vehicles:
a. Shall not idle the vehicle’s primary diesel engine for greater than 5 minutes
at any location, except as noted in Subsection (d) of the regulation; and
b. Shall not operate a diesel-fueled auxiliary power system (APS) to power a
heater, air conditioner, or any ancillary equipment on that vehicle during
sleeping or resting in a sleeper berth for greater than 5 minutes at any
location when within 1,000 feet of a restricted area, except as noted in
Subsection (d) of the regulation.
Signs must be posted in the designated queuing areas and job sites to remind drivers of the 5-
minute idling limit. The specific requirements and exceptions in the regulation can be
reviewed at the following website: www.arb.ca.gov/msprog/truck-idling/2485.pdf.
AQ-2 Particulate Matter Control Measures. During all construction and ground-disturbing activities,
the applicant shall implement the following particulate matter control measures and detail each
measure on the project grading and building plans:
1. Reduce the amount of disturbed area where possible.
2. Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne
dust from leaving the site and from exceeding the SLOAPCD’s limit of 20% opacity
for greater than 3 minutes in any 60-minute period. Increased watering frequency
would be required whenever wind speeds exceed 15 miles per hour (mph). Reclaimed
non-potable) water should be used whenever possible.
1. All dirt stockpile areas (if any) shall be sprayed daily and covered with tarps or other
dust barriers as needed.
2. Permanent dust control measures identified in the approved project revegetation and
landscape plans shall be implemented as soon as possible, following completion of
any soil-disturbing activities.
3. Exposed grounds that are planned to be reworked at dates greater than 1 month after
initial grading shall be sown with a fast germinating, non-invasive, grass seed and
watered until vegetation is established.
4. All disturbed soil areas not subject to revegetation shall be stabilized using approved
chemical soil binders, jute netting, or other methods approved in advance by the
SLOAPCD.
5. All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as
possible. In addition, building pads shall be laid as soon as possible after grading
unless seeding or soil binders are used.
6. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved
surface at the construction site.
7. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall
maintain at least 2 feet of freeboard (minimum vertical distance between top of load
and top of trailer) in accordance with California Vehicle Code (CVC) Section 23114.
8. “Track out” is defined as sand or soil that adheres to and/or agglomerates on the
exterior surfaces of motor vehicles and/or equipment (including tires) that may then
fall onto any highway or street as described in CVC Section 23113 and California
Water Code (CWC) Section 13304. To prevent track out, designate access points and
require all employees, subcontractors, and others to use them. Install and operate a
track-out prevention device” where vehicles enter and exit unpaved roads onto
paved streets. The track-out prevention device can be any device or combination of
devices that are effective at preventing track out, located at the point of intersection
of an unpaved area and a paved road. Rumble strips or steel plate devices need
periodic cleaning to be effective. If paved roadways accumulate tracked-out soils, the
track-out prevention device may need to be modified.
9. Sweep streets at the end of each day if visible soil material is carried onto adjacent
paved roads. Water sweepers shall be used with reclaimed water where feasible.
Roads shall be pre-wetted prior to sweeping when feasible.
10. All PM10 mitigation measures required should be shown on grading and building
plans.
11. The contractor or builder shall designate a person or persons whose responsibility is
to ensure any fugitive dust emissions do not result in a nuisance and to enhance the
implementation of the mitigation measures as necessary to minimize dust complaints
and reduce visible emissions below the SLOAPCD’s limit of 20% opacity for greater
than 3 minutes in any 60-minute period. Their duties shall include holidays and
weekend periods when work may not be in progress (for example, wind -blown dust
could be generated on an open dirt lot). The name and telephone number of such
persons shall be provided to the SLOAPCD Compliance Division prior to the start of
any grading, earthwork, or demolition (Contact Tim Fuhs at 805-781-5912).
AQ-3 Geologic Evaluation. Prior to initiation of ground-disturbing activities, the applicant shall retain
a registered geologist to conduct a geologic evaluation of the property, including sampling and
testing for NOA in full compliance with SLOAPCD requirements and the CARB ATCM for
Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105). This
geologic evaluation shall be submitted to the City Community Development Department upon
completion. If the geologic evaluation determines that the project would not have the potential to
disturb NOA, the applicant must file an Asbestos ATCM exemption request with the SLOAPCD.
AQ-4 Naturally Occurring Asbestos Control Measures. If NOA are determined to be present onsite,
proposed earthwork, demolition, and construction activities shall be conducted in full compliance
with the various regulatory jurisdictions regarding NOA, including the CARB ATCM for
Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105) and
requirements stipulated in the National Emission Standard for Hazardous Air Pollutants
NESHAP; 40 Code of Federal Regulations [CFR] Section 61, Subpart M – Asbestos). These
requirements include, but are not limited to, the following:
1. Written notification, within at least 10 business days of activities commencing, to the
SLOAPCD;
2. Preparation of an asbestos survey conducted by a Certified Asbestos Consultant; and
3. Implementation of applicable removal and disposal protocol and requirements for
identified NOA.
AQ-5 Asbestos-Containing Material. Prior to issuance of demolition permits, the applicant shall
provide an asbestos report that was prepared by a certified asbestos consultant. If ACM are
determined to be present, at least 10 working days prior to any demolition work the applicant
shall provide notification to SLOAPCD of such work. The notification shall include an asbestos
report that was prepared by a certified asbestos consultant. ACM removal and disposal shall
follow the requirements of the National Emission Standards for Hazardous Air Pollutants
Regulation (NESHAP) Subpart M and of the SLOAPCD.
Monitoring Program: These measures shall be incorporated onto Final Map and project grading /
building plans for review and approval by the City Community Development Department. Compliance
shall be verified by the City during regular inspections, in coordination with the SLOAPCD, as necessary.
Biological Resources
BIO-1 Implement a Rare Plant Mitigation Program that ensures no net loss of Cambria morning
glory on the project site. Prior to any tract improvements, a Rare Plant Mitigation Program shall
be implemented for Cambria morning glory and shall be overseen by a qualified botanist
approved by the City. As a component of the program, seed shall be collected from Cambria
morning glory plants during the appropriate season prior to tract grading activities. Using
standard procedures, the qualified botanist shall clean and store the seeds until the receiving sites
shown on the project plans are ready. Suitable habitat of 2,180 square-feet in size outside of the
development area (as designated on the site plans in the creek setback zone) shall be designated
as the mitigation site that will be maintained in a natural state and not be subject to mowing
earlier than June 1 each year. The areas will be maintained as grassland habitat and no planting of
ornamental species or other adverse modifications (such as grazing activities) will be allowed.
The mitigation site shown on the project plans is twice the size as the areas currently occupied by
the rare plant occurrences (2,180 square-feet of habitat created for 1,076 square-feet of habitat
impacted). This equates to a 2:1 mitigation ratio (habitat created to habitat impacted) to ensure a
minimum 1:1 replacement ratio is achieved. Topsoil from each of the four occurrences will be
collected in 6-inch lifts and stored for top-dressing the mitigation site once grading of the pads is
complete. As needed, the mitigation site should be prepared for planting by removal of non-native
species or other measures as necessary, then applying the salvaged topsoil. Once topsoil has been
layered evenly through the area, collected seed should be hand-broadcasted into suitable locations
by the qualified botanist and covered with compost. Seed may also be incorporated into the native
erosion control seed mix described in the Native Erosion Control Seed Mix table under
Mitigation Measure BIO-9 and applied to other grassy areas of the site as part of the erosion
control effort. Depending on the season when construction starts, the qualified botanist may also
potentially salvage plants (i.e., dig them up when soils are moist) and transplant them to
containers to be maintained until the mitigation sites are ready for planting.
BIO-2 Conduct annual monitoring and implement adaptive management measures for 5 years to
ensure no net loss of Cambria morning glory onsite. The Rare Plant Mitigation Program shall
include annual monitoring and maintenance of the mitigation site to ensure success of the
program. Monitoring by a qualified botanist shall occur during the spring growing season
between April 15 and May 15 each year) to ensure successful establishment of planted
propagules. The established rare plants shall be mapped to evaluate the goal of no net loss of the
species onsite. The measurable objective shall be to have at least 1,076 sf of occurrence
comprised of approximately 300 Cambria morning glory plants. Appropriate vegetation sampling
techniques shall be used to assess the areal cover of vegetation to evaluate the status of the
established occurrences. If the success criteria of having approximately 300 plants covering 1,076
sf within the creek setback zone is not reached by the third year of monitoring, remedial actions
such as collecting more seed and distributing it in suitable areas should be employed, with a
corresponding additional year of monitoring. Other activities to increase the success of the rare
plant mitigation effort could include non-native plant species removal within the mitigation site to
reduce competition, additional seed application, or supplemental irrigation during periods of
prolonged drought. The qualified botanist shall prepare annual reports for the applicant detailing
the methods and results of the mitigation effort and monitoring effort. The applicant shall be
responsible for submitting the report to the City on an annual basis (by December 31 of each
year) for the 5-year monitoring period or until the final success criteria described above are met.
BIO-3 To the extent feasible, avoid initial site grading in the winter months. The burrowing owl has
been recorded in the vicinity of the project from October to the end of April. If initial vegetation
removal and site grading for the tract improvements is conducted outside of this period, potential
effects on this species would be avoided and no further mitigation would be required. Restricting
the time period for earth-moving activities is also required to avoid or minimize the potential for
erosion and sedimentation (see Mitigation Measure BIO-9). If initial grading work must
commence during the time period that burrowing owls may be present onsite, preconstruction
surveys for this species shall be included in the survey effort described in Mitigation Measure
BIO-4 prior to vegetation removal or tract improvements.
BIO-4 Conduct a preconstruction survey and avoid construction in areas occupied by special-
status wildlife species until relocated or they have left the site. Within 7 days prior to the
start of vegetation/tree removal, ground-disturbing activities, or demolition of existing structures,
a biologist approved by the City shall survey the project impact area to identify whether nesting
birds, roosting bats, monarch butterfly overwintering populations, obscure bumble bee, and/or
California legless lizard are present on site. A separate survey shall be conducted for any phase of
the project not conducted concurrently or within 10 days of cessation of the previous phase (i.e.,
structure demolition conducted prior to general site grading). The biologist shall use appropriate
survey techniques for the special-status species identified in the 2020 BRA as having potential to
occur onsite. For example, burrows shall be examined with binoculars or wildlife cameras, and
inspected for whitewash or prey remains. Leaf litter and cover objects shall be searched for
northern California legless lizards. Potential bat roost sites shall be inspected for sign of roosting
bats such as guano or prey remains. If any of these species are found onsite, the biologist shall
coordinate with the City, and CDFW as appropriate, on methods to ensure the successfu l
relocation of individuals to suitable habitat nearby. In some cases, CDFW may recommend
creating structures for displaced woodrats and bats. Burrowing owls can be discouraged from
using burrows onsite, or occupied burrows can be avoided until the owls have left the area. Bats
can be restricted from roost sites by placing netting over their entrances after they have left the
roost for night-time foraging. The wildlife protection measures to be employed will be based on
the results of the survey and the particular characteristics of their use of the site, in coordination
with CDFW and the construction engineer. If no special-status animal species are found onsite
during the preconstruction survey, work may proceed with the implementation of the following
Mitigation Measures BIO-5 through BIO-7.
BIO-5 Prepare and present a Worker Environmental Awareness Program. Prior to any vegetation
removal or tract improvements, a qualified biologist shall prepare a Worker Environmental
Awareness Program that will be presented to all project personnel. This program shall detail
measures to avoid and minimize impacts on biological resources. It shall include a description of
special-status species potentially occurring on the project site and their natural history, the status
of the species and their protection under environmental laws and regulations, and the penalties for
take. Recommendations shall be given as to actions to avoid take should a special-status species
be found on the project site. Other aspects of the training shall include a description of general
measures to protect wildlife, including:
1. Delineation of the allowable work area, staging areas, access points, and limits to
vehicle access;
2. Storage of all pipes, metal tubing, or similar materials stored or stacked on the project
site for one or more overnight periods shall be either securely capped before storage
or thoroughly inspected for wildlife before the materials are moved, buried, capped,
or otherwise used.
3. Inspection of materials stored onsite, such as lumber, plywood, and rolls of silt fence,
for wildlife that may have sheltered under or within the materials;
4. Use of netting to exclude birds from nesting in construction materials;
5. Construction of escape ramps in all excavations and trenches more than 6 inches
deep;
6. Contact information for the City-approved biologist and instructions should any
wildlife species be detected in the work site;
7. Dust suppression methods during construction activities when necessary to meet air
quality standards and protect biological resources; and
8. Methods for containment of food-related trash items (e.g., wrappers, cans, bottles,
food scraps), small construction debris (e.g., nails, bits of metal and plastic), and
other human generated debris (e.g., cigarette butts) in animal-proof containers and
removal from the site on a weekly basis.
All project personnel who have attended the training shall sign an attendance sheet. The
program shall be repeated for any new crews that arrive subsequently on the site.
BIO-6 Install high-visibility construction and silt fence along the creek corridor to delineate the
allowable work area, exclude wildlife from the site, and protect the stream habitat. Prior to
vegetation removal or tract improvements, and during subsequent residential development for
Lots 1-7, a high-visibility construction fence at least 4 feet tall together with a silt fence, or an
approved wildlife exclusion fence, shall be erected along the creek corridor to delineate the limits
of grading and vehicle access. If possible, the fence shall be erected along the creek setback line,
and encroachment into the setback shall be kept at a minimum. In no case shall ground
disturbance occur within the riparian habitat or below the top of bank without obtaining proper
permits from regulatory agencies. The type of fence used may be a combination of wildlife
exclusion and silt fence (i.e., ERTEC Triple-function E-fence) or similar materials that would
serve the purposes of safety/construction area delineation, wildlife exclusion, and siltation
prevention. The fence shall be checked weekly by construction personnel for needed
maintenance.
BIO-7 Conduct biological monitoring for special-status wildlife species while the property is
cleared and graded, and structures are removed. A qualified biologist shall monitor the
removal of structures, materials, and vegetation that may provide cover for obscure bumble bee,
northern California legless lizards, and bat roosting sites. The biologist shall be onsite daily until
all materials are removed and all vegetation has been cleared. If any special-status species are
found, work shall be delayed until the individuals have left the work area or CDFW shall be
notified to obtain authorization for capture and relocation.
BIO-8 Avoid vegetation removal within the riparian habitat during the overwintering season .
Vegetation removal within the riparian area shall be conducted outside of the overwintering
season for monarch butterfly (late October through February) and obscure bumble bee (late
October through January) to avoid disturbance to species potentially inhabiting riparian
vegetation.
BIO-9 Install erosion and sediment BMPs and revegetate graded areas. The following erosion and
sedimentation control BMPs are required to be implemented during vegetation removal, tract
improvements, during individual lot construction, and after the construction phases of the project:
1. If possible, the potential for erosion and sedimentation shall be minimized by
scheduling construction to occur outside of the rainy season, which is typically
defined as October 15 through April 15. Adherence to this measure would also serve
as avoidance for the burrowing owl, as described in Mitigation Measure BIO-3.
2. To minimize site disturbance, all construction related equipment shall be restricted to
established roads, construction areas, and other designated staging areas. The creek
setback zone shall be clearly marked as described in Mitigation Measure BIO-6.
3. Prior to any site disturbance during tract improvements or individual lot construction,
a Sediment and Erosion Control Plan shall be prepared by a qualified engineer. The
use of silt fence, straw wattles, erosion control blankets, straw bales, sandbags, fiber
rolls, and other appropriate techniques should be employed to protect the drainage
features on and off the property. Biotechnical approaches using native vegetation
shall be used as feasible. All areas with soil disturbance shall have appropriate
erosion controls and other stormwater protection BMPs installed to prevent erosion
potential. All sediment and erosion control measures shall be installed per the
engineer’s requirements prior to the initiation of site grading if planned to occur
within the rainy season.
4. Spill kits shall be maintained on the site, and a Spill Response Plan shall be in place.
5. No vehicles or equipment shall be refueled within 100 feet of wetland areas, riparian
habitat and/or drainage features, and refueling areas shall have a spill containment
system installed. No vehicles or construction equipment shall be stored overnight
within 100 feet of these areas unless drip pans or ground covers are used. All
equipment and vehicles shall be checked and maintained on a daily basis to ensure
proper operation and to avoid potential leaks or spills. Construction staging areas
shall be located in a location where spills would not drain into aquatic habitats.
6. No concrete washout shall be conducted on the site outside of an appropriate
containment system. Washing of equipment, tools, etc. should not be allowed in any
location where the tainted water could enter onsite drainages.
7. The use of chemicals, fuels, lubricants, or biocides shall be in compliance with all
local, state, and federal regulations. All uses of such compounds shall observe label
and other restrictions mandated by the U.S. Environmental Protection Agency,
California Department of Food and Agriculture, and other state and federal
legislation.
8. All project-related spills of hazardous materials within or adjacent to the project site
should be cleaned up immediately.
9. All areas with soil disturbance shall have appropriate erosion controls and other
stormwater protection BMPs installed to prevent erosion potential. Silt fencing,
erosion control blankets, straw bales, sandbags, fiber rolls, and/or other types of
materials prescribed on the plan shall be implemented to prevent erosion and
sedimentation. Biotechnical approaches using native vegetation shall be used as
feasible.
10. Areas with disturbed soils shall be restored under the direction of the project engineer
in consultation with a qualified restoration ecologist as detailed above. Methods may
include recontouring graded areas to blend in with existing natural contours, covering
the areas with salvaged topsoil containing native seedbank from the site, and/or
applying the native seed mix as described in the table below. Native seed mix shall
be applied to the graded areas in the creek setback area through either direct hand
seeding or hydroseeding methods. Seeding with the native erosion control seed mix
should be provided on all disturbed soil areas prior to the onset of the rainy season
by October 15).

BIO-10 Obtain necessary permits for impacts in jurisdictional areas, implement a compensatory
mitigation program, and monitor the success of the program to ensure no net loss of
Riparian/Wetland habitat or other waters on the subject property. Prior to any vegetation
removal or site disturbance within the areas delineated as jurisdictional features (Figure 5,
Aquatic Resources Delineation 2021), the applicant shall provide documentation to the City that a
Clean Water Act Section 404 Permit from USACE, a Clean Water Act Section 401 Water Quality
Certification from RWQCB, and a California Fish and Game Code Section 1602 Lake and
Streambed Alteration Agreement from CDFW have been obtained or have been determined by
the regulatory agencies to not be required.
If regulatory permits are required, prior to the initiation of vegetation removal or tract
improvements, the applicant shall retain a qualified biological monitor to ensure compliance with
all Clean Water Act and CDFW permit requirements during work adjacent to the creek. The
monitor shall be present during the installation of the construction fencing delineating the limits
of work in relation to the edge of riparian, creek top of bank , and 20-foot creek setback buffer, as
described in Mitigation Measure BIO-6. Since the Cambria morning glory compensatory
mitigation site is to be located within this buffer, the monitor shall direct appropriate wildlife
exclusion and erosion control BMPs to protect riparian habitat during site preparation for
planting. The monitor shall be present during construction of the rip rap pad and any other work
within the creek setback area on stormwater structures. The monitor shall also oversee removal of
non-native tree species and site preparation for tree planting within the setback. If a Habitat
Mitigation and Monitoring Plan (HMMP) is required by the regulatory agencies, the applicant
shall provide a copy of the plan to the City and the biological monitor shall be responsible for
successful implementation of the plan.
BIO-11 Record a Biological Easement and Biological Easement Agreement protecting riparian
area: A Biological Easement and Biological Easement Agreement shall be recorded in
conjunction with the final map recordation. The easement agreement shall be developed by the
applicant in a format provided by the City. The following activities are permitted within the
biological easement, subject to the review and approval by the City Sustainability and Natural
Resources Official:
1. Stormwater improvements.
2. Removal of non-native trees.
3. Restoration and creek bank stabilization activities.
No future paving or structures shall be permitted within the biological easement. Creek
setback standards shall be applied to the easement area, consistent with municipal code
requirements.
Monitoring Program: These conditions and measures shall be noted on Final Map and all grading and
construction plans. The City Community Development Department and Natural Resources Manager shall
verify compliance.
Cultural Resources
CR-1 Discovery of Previously Unidentified Cultural Resources. In the event that historical or
archaeological remains are discovered during ground-disturbing activities associated with the
project, an immediate halt work order shall be issued, and the City Community Development
Director shall be notified. A qualified archaeologist shall conduct an assessment of the resourc es
and formulate proper mitigation measures, if necessary. After the find has been appropriately
mitigated, work in the area may resume. These requirements shall be noted on the project’s final
map and all improvement/construction plans.
CR-2 Discovery of Human Remains. In the event that human remains are exposed during ground-
disturbing activities associated with the project, an immediate halt work order shall be issued, and
the City Community Development Director shall be notified. California Health and Safety Code
Section 7050.5 requires that no further disturbance of the site or any nearby area reasonably
suspected to overlie adjacent human remains shall occur until the County Coroner has made the
necessary findings as to origin and disposition pursuant to PRC Section 5097.98. If the remains
are determined to be of Native American descent, the coroner shall notify the Native American
Heritage Commission (NAHC) within 24 hours. These requirements shall be noted on the
project’s final map and all improvement/construction plans.
Monitoring Program: These conditions shall be noted on Final Map and all grading and construction
plans. The City Community Development Department shall verify compliance, including preparation and
implementation of the Monitoring Plan, and review and approval of cultural resources monitoring reports
documenting compliance with required Mitigation Measures.
Noise
N-1 For the entire duration of the construction phase of the project, the following BMPs shall be
adhered to:
1. Stationary construction equipment that generates noise that exceeds 60 dBA at the
project boundaries shall be shielded with the most modern noise control devises (i.e.,
mufflers, lagging, and/or motor enclosures).
2. Impact tools (e.g., jack hammers, pavement breakers, rock drills, etc.) used for
project construction shall be hydraulically or electrically powered wherever possible
to avoid noise associated with compressed-air exhaust from pneumatically powered
tools.
3. Where use of pneumatic tools is unavoidable, an exhaust muffler on the compressed
air exhaust shall be used.
4. All construction equipment shall have the manufacturers’ recommended noise
abatement methods installed, such as mufflers, engine enclosures, and engine
vibration insulators, intact and operational.
5. All construction equipment shall undergo inspection at periodic intervals to ensure
proper maintenance and presence of noise control devices (e.g., mufflers, shrouding,
etc.).
N-2 Construction plans shall note construction hours, truck routes, and all construction noise BMP,
and shall be reviewed and approved by the City Community Development Department prior to
issuance of grading/building permits. The City shall provide and post signs stating these
restrictions at construction entry sites prior to commencement of construction and maintained
throughout the construction phase of the project. All construction workers shall be briefed at a
preconstruction meeting on construction hour limitations and how, why, and where BMP
measures are to be implemented.
Monitoring Program: These measures shall be incorporated into Final Map and project grading and
building plans for review and approval by the City Community Development Department. Compliance
shall be verified by the City during regular inspections. Tribal Cultural Resources
TC-1 Culturally Affiliated Native American Monitor. A representative from the Salinan Tribe
shall be notified prior to any ground disturbing activities to provide for on-site monitoring. If
cultural resources are encountered during subsurface earthwork activities, all ground
disturbing activities within a 25-foot radius of the find shall cease and the City shall be
notified immediately consistent with the requirements of Mitigation Measures CR-1 and CR-
2.
Monitoring Program: These measures shall be incorporated into Final Map and project grading and
building plans for review and approval by the City Community Development Department. Compliance
shall be verified by the City during regular inspections.
Wildfire
WF-1 Vegetation/Fuel Management Plan. Prior to issuance of any construction permit, the applicant
shall provide a vegetation/fuel management plan prepared by a registered professional forester or
certified arborist for each lot. The plan shall identify fuel load reduction techniques, including
vegetation removal and trimming, to increase defensible space around residential structures and
driveways/access roads. The plan shall also identify appropriate standards for installation of new
landscaping, such as requirements for drought-tolerant and fire-resistant species.
WF-2 Additional Fire Hazard Reductions. Future development would incorporate the following fire
reduction methods identified by the 2020 Wildland Fire Protection Report (Neumann)to reduce
wildland fire risk:
1. Rain gutters, when not adequately maintained, will collect leaf material which
becomes a receptive fuel bed for embers and sparks and can then transmit fire
underneath the non-combustible roof materials. Rain gutters should be protected by
noncombustible leaf shields or not allowed.
2. Record on all lots a deed restriction that allows for only non-combustible fences and
decks in the subdivision.
3. Record on all lots a deed restriction that allows for fire resistant landscaping in the
back yards of the subdivision.
4. Require enclosed eves on all structures within the subdivision.
5. Install fireproof vents on all structures (fire-rated, flame and ember resistant).
6. Working with the biologist, remove the non-native vegetation in the creek, riparian
area,
7. reduce the fuel load.
8. Install a non-combustible wall (block or steel stud /stucco) wall 36 inches in height
all around the northern perimeter of the subdivision. The wall shall begin at the
westernmost property line and continue to the 20-foot setback at the west side of the
creek and shall continue beginning at the 20-foot setback at the east side of the creek,
terminating at the property line of CAL FIRE Station #12. The purpose of this wall is
to interrupt fire progression from the north onto the proposed lots without obstructing
the very desirable view of the open space.
Monitoring Program: This measure shall be incorporated into Final Map and noted on all grading and
construction plans. The City Community Development Department shall verify compliance through
initial and regular inspections.
If the Community Development Director or hearing body determines that the above mitigati on measures
are ineffective or physically infeasible, they may add, delete or modify the mitigation to meet the intent of
the original measures.
Please note that section 15070 (b) (1) of the California Administrative Code requires the applicant to
agree to the above mitigation measures before the proposed Mitigated Negative Declaration is released
for public review. This project will not be scheduled for public review and hearing until this signed
original is returned to the Community Development Department.
