Planning Division:
1. Mitigation Measure AIR-1
The following best practice measures to reduce impacts to air quality shall be incorporated by
the project applicant, subject property owners, or third-party contractors during construction
activities on the project site. These measures are intended to reduce criteria air pollutants that
may originate from the site during the course of land clearing and other construction operations.
Diesel PM Exhaust from Construction Equipment and Commercial On-Road Vehicles Greater than
10,000 Pounds
• All on- and off-road equipment shall not idle for more than five minutes. Signs shall be
posted in the designated queuing areas and/or job sites to remind drivers and operators
of the five-minute idling limit.
• Idling, staging and queuing of diesel equipment within 1,000 feet of sensitive receptors is
prohibited.
• All construction equipment shall be maintained in proper tune according to the
manufacturer’s specifications. Equipment must be checked by a certified mechanic and
determined to be running in proper condition before the start of work.
• Install diesel particulate filters or implement other CARB-verified diesel emission control
strategies.
• 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 100 feet of a
restricted areas.
• To the extent feasible, truck trips shall be scheduled during non-peak hours to reduce
perk hour emissions.
Operational TAC Emissions
• All mobile and stationary Toxic Air Contaminants (TACs) sources shall comply with
applicable Airborne Toxic Control Measures (ATCMs) promulgated by the CARB
throughout the life of the project (see http:www.arb.ca.gov/toxics/atcm/atcm.htm).
• Stationary sources shall comply with applicable District rules and regulations.
Fugitive Dust
Construction activities can generate fugitive dust that can be a nuisance to local residents and
businesses near a construction site. Dust complaints could result in a violation of the District’s
“Nuisance” and “Fugitive Dust” Rules 200 and 205, respectively. The following is a list of measures
that may be required throughout the duration of the construction activities:
• Reduce the amount of the disturbed area where possible.
• Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust
from leaving the site. An adequate water supply source must be identified. Increased
watering frequency would be required whenever wind speeds exceed 15 mph. Reclaimed
(non-potable) water should be used whenever possible.
• All dirt stockpile areas should be sprayed daily as needed, covered, or a District approved
alternative method will be used.
• Permanent dust control measures identified in the approved project revegetation and
landscape plans should be implemented as soon as possible following completion of any
soil disturbing activities.
• Exposed ground areas that will be reworked at dates greater than one month after initial
grading should be sown with a fast-germinating non-invasive grass seed and watered until
vegetation is established.
• All disturbed soil areas not subject to re-vegetation should be stabilized using approved
chemical soil binders, jute netting, or other methods approved in advance by the Butte
County Air Quality Management District.
• All roadways, driveways, sidewalks, etc. to be paved should be completed as soon as
possible. In addition, building pads should be laid as soon as possible after grading unless
seeding or soil binders are used.
• Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved
surface at the construction site.
• All trucks hauling dirt, sand, soil, or other loose materials are to be covered or should
maintain at least two feet of freeboard (minimum vertical distance between top of load
and top of trailer) in accordance with local regulations.
• Install wheel washers where vehicles enter and exit unpaved roads onto streets, or wash
off trucks and equipment leaving the site.
• Sweep streets at the end of each day if visible soil material is carried onto adjacent paved
roads. Water sweepers with reclaimed water should be used where feasible.
• Post a sign in prominent location visible to the public with the telephone numbers of the
contractor and the Butte County Air Quality Management District - (530) 332-9400 for
any questions or concerns about dust from the project.
All fugitive dust mitigation measures required should be shown on grading and building plans. In
addition, the contractor or builder should designate a person or persons to monitor the dust
control program and to order increased watering, as necessary, to prevent transport of dust
offsite. Their duties shall include holidays and weekend period when work may not be in
progress. The name and telephone number of such persons shall be provided to the District prior
to land use clearance for map recordation and finished grading of the area.
Please note that violations of District Regulations are enforceable under the provisions of
California Health and Safety Code Section 42400, which provides for civil or criminal penalties of
up to $25,000 per violation.
Plan Requirements: The note shall be placed on a separate document which is to be recorded
concurrently with the map or on an additional map sheet. This note shall also be placed on all
building and site development plans.
Timing: Requirements of the condition shall be adhered to throughout all grading and
construction periods.
Monitoring: The Butte County Department of Development Services and the Public Works
Department shall ensure that the note is placed on a separate document which is to be recorded
concurrently with the map or on an additional map sheet. Building inspectors shall spot check
and shall ensure compliance on-site. Butte County Air Pollution Control District inspectors shall
respond to nuisance complaints.
2. Mitigation Measure BIO-1
If project construction activities, including ground disturbance or vegetation removal occur
during the nesting season for birds protected under the Migratory Bird Treaty Act (MBTA) and
California Department Fish & Game Code (CDFC) (approximately February 1 – August 31), the
project proponent shall retain a qualified biologist to perform preconstruction surveys for nesting
bird species. Surveys to identify active bird nests shall be conducted within and 250 feet around
the footprint of proposed construction site. The survey shall be conducted within 7 days prior to
the initiation of construction activities. In the event that an active nest is observed, a species
protection buffer shall be established. The species protection buffer will be defined by the
qualified biologist based on the species, nest type and tolerance to disturbance. Construction
activity shall be prohibited within the buffer zones until the young have fledged or the nest fails.
Nests shall be monitored by a qualified biologist once per week and a report submitted to the
Butte County Department of Development Services.
Plan Requirements: Perform protocol-level surveys for migratory birds protected by the
California Department Fish & Game Code and the Migratory Bird Treaty Act. This measure shall
be recorded on an additional map sheet to the Parcel Map.
Timing: Requirements of the condition shall be adhered to prior to and during construction
activities planned to occur during nesting seasons for CDFC and MBTA species (between February
1 and August 31).
Monitoring: The Butte County Department of Development Services and the Public Works
Department shall ensure that the note is recorded an additional map sheet of the Parcel Map.
Department of Development Services shall ensure the condition is met at the time of
construction activities.
3. Mitigation Measure BIO-2
Place the following note to be recorded on an additional map page of the Parcel Map that states:
“Prior to any development activity or the issuance of any permit or approval removing or
encroaching upon oak trees on the project site (this generally includes the canopy drip-
line of trees within the area of ground disturbance and trees subject to changes in
hydrologic regime), the applicant/developer shall complete one of the following
measures to the satisfaction of the Director of Development Services or is/her designee:
A. An Oak Tree Evaluation Plan shall be prepared for areas that are proposed for
development (e.g., dwelling, accessory structures, yards, driveways) by a qualified
professional having experience in California Oak Woodlands and is either a certified
arborist, qualified wildlife biologist or registered professional forester shall be submitted
for review and approval by the Director of Development Services or his/her designee that
includes the following:
1) A survey showing the location of oak trees 5 inches or more in diameter at
breast height, as defined by PRC §21083.4(a);
2) The removal of all oak trees 5 inches or more in diameter at breast height
shall be mitigated. It shall be mitigated by one or more of the following:
replanting and maintaining oak trees, establishing conservation
easements, contributing funds for off-site oak woodlands conservation,
and/or other mitigation measures developed by Butte County. Replanting
oak trees cannot account for more than one-half of the mitigation.
Replanted oak trees shall be maintained for a period of seven years after
they are planted. If any of the replanted oak trees die or become diseased,
they shall be replaced and maintained for seven years after the new oak
trees are planted;
3) A replanting schedule and diagram for trees removed or encroached upon
by permit activities consistent with PRC §21083.4(b)(2), applicable
mitigation measures, and Butte County Ordinance, if any, shall be
submitted to and approved by the Director of Development Services or
his/her designee. Replanted trees shall be planted in areas deemed
appropriate by the Plan, considering future lot development, interference
with foundations, fencing, roadways, driveways, and utilities. Trees
planted shall be protected from livestock and other animals;
4) Oak Tree protection measures for trees to be retained within the project
site shall be included in construction specifications. Prior to construction
or surface disturbance, a protective fence or brightly colored staked
boundary shall be placed 5 feet beyond the established critical rooting
zone (CRZ) of the oak or group of oaks being protected. A warning sign
shall be prominently displayed on each fence. The sign should be a
minimum of 16 x 24 inches, brightly colored and be clearly visible, even
from vehicles. The sign must clearly indicate that the CRZ is a restricted
area. Orange safety triangles may suffice if other signage cannot be
constructed. A high visibility plastic mesh fence is recommended to
maximize the visibility of protected tree areas. Wire with bright-colored
flags placed at equal intervals can also be a suitable barrier so long as it
maintains high visibility. Protective fencing shall remain in place until final
inspection by the qualified professional. No vegetation removal, soil
disturbance, or other development activities shall occur within the tree
zone in order to protect root systems and minimize compaction of the soil,
unless authorized by Oak Tree Mitigation Plan; and
5) Conservation easements or funds for off-site oak woodlands conservation
shall be proposed to and approved by the Director of Development
Services or his/her designee; or
B. Provide proof of compliance with the adopted Butte County Oak Woodland
Mitigation Ordinance currently under preparation; or
C. Provide proof of compliance with all required avoidance and minimization
measures, and payment of all applicable fees to mitigate for blue oak woodland impacts
as provided in the Butte Regional Conservation Plan, as adopted by Butte County.
Plan Requirements: No vegetation removal, grading, road construction, or other earthwork
resulting in the removal or encroachment upon oak trees on the project site shall be permitted
until the mitigation measure is satisfied by the applicant/developer completing one of the
specified measures to the satisfaction of the Director of Development Services or their designee.
Timing: Requirements of the condition shall be satisfied prior to any development activity or the
issuance of any grading, building, or the approval of any improvement plans on the parcels.
Monitoring: The Butte County Department of Development Services and Department of Public
Works shall ensure that the note is placed on a separate document which is to be recorded
concurrently with the map or on an additional map sheet. At the time of building permit
application, the Development Services Department will reference this requirement on any
grading, or building permit site plans and verify that an Oak Tree Mitigation Plan has been
submitted to and approved by the Director of Development Services or his/her designee. Butte
County building inspectors shall ensure compliance on-site.
4. Mitigation Measure CUL-1
If grading activities reveal the presence of prehistoric or historic cultural resources (i.e., artifact
concentrations, including arrowheads and other stone tools or chipping debris, cans glass, etc.;
structural remains; or human skeletal remains) work within 50 feet of the find shall immediately
cease until a qualified professional archaeologist can be consulted to evaluate the find and
implement appropriate mitigation procedures. If human skeletal remains are encountered, State
law requires immediate notification of the County Coroner (530.538.7404). If the County Coroner
determines that the remains are in an archaeological context, the Native American Heritage
Commission in Sacramento shall be notified immediately, pursuant to State Law, to arrange for
Native American participation in determining the disposition of such remains. The provisions of
this mitigation shall be followed during construction of all improvements, including land clearing,
road construction, utility installation, and building site development.
Plan Requirements: This note shall be placed on a separate document which is to be recorded
concurrently with the map or on an additional map sheet and shall be shown on all site
development and building plans.
Timing: This measure shall be implemented during all site preparation and construction
activities.
Monitoring: The Department of Development Services and/or Public Works Department shall
ensure the note is placed on a separate document which is to be recorded concurrently with the
map or on an additional map sheet. Should cultural resources be discovered, the landowner shall
notify the Planning Division and a professional archaeologist. The Planning Division shall
coordinate with the developer and appropriate authorities to avoid damage to cultural resources
and determine appropriate action. State law requires the reporting of any human remains.
5. Mitigation Measure NOI-1
