with the conditions and provision of the previous use permit. Uses not authorized by a valid use permit will be subject to
abatement proceedings.
(7)
All applicable permits from other county departments shall be obtained prior to operating the outdoor vendor business on the
premises.
(i)
Open space easements. The board of supervisors may require, on appeal or otherwise, and the planning commission or board of
zoning adjustments may recommend, as a condition of approval of a development application, the dedication of an open space
easement on all or a portion of the property to be developed. Applications for development shall include, but not be limited
to, applications for general plan amendments, specific plan amendments, rezonings, major and minor subdivisions, use permits
or precise development plans. Prior to requiring an open space easement or an offer of easement pursuant to this section,

(k)
Seasonal farm worker housing shall meet the following standards:
(1)
Seasonal farm worker housing shall be located on parcels of one point five (1.5) acres or more having an agricultural or resources
and rural development general plan land use designation. Such parcels shall be owned by the applicant. If less than ten (10)
acres, such parcels shall be located within one (1) mile of a minimum of twenty (20) contiguous acres of land cultivated and
either owned or long term leased by the applicant.
(2)
Seasonal farm worker housing shall be located on parcels having direct access to a county maintained road. If a private road
is to provide such access, the applicant shall file with the permit and resource management department a written agreement
signed by all of the property owners entitled to use such road acknowledging and agreeing to the road's use as access for
the seasonal farm worker housing.
(3)
Seasonal farm worker housing located on parcels of less than ten (10) acres shall house no more than nineteen (19) persons,
including a caretaker, at any time.
(4)
Seasonal farm worker housing and support structures shall be set back a minimum of fifty-five feet (55′) from the center line
of any roadway, sixty feet (60′) from any other property line, forty feet (40′) from any other structure, and forty feet (40′)
from watering troughs, feed troughs, and accessory buildings. Seasonal farm worker housing and support structures shall also
be set back seventy-five feet (75′) from barns, pens, or similar quarters of livestock or poultry.
(5)
Seasonal farm worker housing shall have off-street parking provided at a ratio of one (1) space per four (4) persons housed.
The parking does not need to be covered or paved, but may not be located within any scenic corridor setback unless screened
from public view by buildings, fences, landscaping, or terrain features.
(6)
Seasonal farm worker housing may be either one (1) or two (2) story structures.
(7)
Seasonal farm worker housing shall be occupied no more than one hundred eighty (180) days in any calendar year. The director
of environmental health may restrict the occupancy of seasonal farm worker housing to one hundred thirty-seven (137) days
between July 1 and November 15 in any calendar year for health and safety reasons.
(8)
Seasonal farm worker housing having accommodations for at least six (6) persons may have a single caretaker unit per parcel
occupied year-round provided year-round occupancy of the caretaker unit is authorized by the director of environmental health.
(9)
Seasonal farm worker housing shall not be located within any floodway.
(10)
Seasonal farm worker housing located within the one hundred-year flood elevation shall have the structure of the finished
floor of the living quarters above the one hundred-year flood level, but may have a storage area before the living quarters.
(11)
Seasonal farm worker housing located within the one hundred-year flood elevation shall have its septic tank and disposal field
at least one hundred feet (100′) removed from the one hundred-year flood elevation unless otherwise authorized by the director
of environmental health.
(12)
Seasonal farm worker housing shall be maintained in such a manner so as not to constitute a zoning violation or a health and
safety hazard.
(13)
Prior to the issuance of a building permit for seasonal farm worker housing, the applicant shall place on file with the permit
and resource management department an affidavit that the seasonal farm worker housing will be used to house persons employed
for agricultural purposes. Further, a covenant shall be recorded, in a form satisfactory to county counsel, acknowledging
and agreeing that park and traffic mitigation fees for the seasonal farm worker housing shall be waived unless and until the
housing units are no longer used to house persons employed for agricultural purposes and further acknowledging and agreeing
that in the event the housing units are converted to some other use the park and traffic mitigation fees existent at the time
of conversion shall be immediately due and payable and the housing units shall be either removed or, if the new use is otherwise
permitted, brought into compliance with the provisions of this code and state laws in effect at the time of conversion.
General provisions.
Projects shall be designed to minimize the destruction of protected trees. With development permits, a site plan shall be
submitted that depicts the location of all protected trees greater than nine inches (9″) and their protected perimeters in
areas that will be impacted by the proposed development, such as the building envelopes, access roads, leach fields, etc.
Lot line adjustments, zoning permits and agricultural uses are exempt from this requirement. The provisions of this section
shall not apply to trees which are the subject of a valid timber harvesting permit approved by the state of California. This
section shall not be applied in a manner that would reduce allowable density lower than that permitted as a result of C.E.Q.A.
or by other county ordinances or render a property undevelopable. To achieve this end, adjustments may be made.
Agricultural uses exempt from the tree protection ordinance are as follows: The raising, feeding, maintaining, and breeding
of confined and unconfined farm animals, commercial aquaculture, commercial mushroom farming, wholesale nurseries, greenhouses,
wineries and agricultural cultivation.
Construction standards.
Applicants are encouraged to use a qualified specialist to establish tree protection methods.
(1)
Protected trees, their protected perimeters and whether they are to be retained or removed are to be clearly shown on all
improvement plans. A note shall be placed on the improvement plans that "Construction is subject to requirements established
by Sonoma County to protect certain trees."
(2)
Before the start of any clearing, excavation, construction or other work on the site, every tree designated for protection
on the approved site plan shall be clearly delineated with a substantial barrier (steel posts and barbed wire or chain link
fencing) at the protected perimeter, or limits established during the permit process. The delineation markers shall remain
in place for the duration of all work. All trees to be removed shall be clearly marked. A scheme shall be established for
the removal and disposal of brush, earth and other debris as to avoid injury to any protected tree.
(3)
Where proposed development or other site work must encroach upon the protected perimeter of a protected tree, special measures
shall be incorporated to allow the roots to obtain oxygen, water and nutrients. Tree wells or other techniques may be used
where advisable. No changes in existing ground level shall occur within the protected perimeter unless a drainage and aeration
scheme approved by a certified arborist is utilized. No burning or use of equipment with an open flame shall occur near or
within the protected perimeter (except for authorized controlled burns).
(4)
No storage or dumping of oil, gasoline, chemicals, or other substances that may be harmful to trees shall occur within the
drip line of any tree, or any other location on the site from which such substances might enter the drip line.
(5)
If any damage to a protected tree should occur during or as a result of work on the site, the county shall be promptly notified
of such damage. If a protected tree is damaged so that it cannot be preserved in a healthy state, the director of the permit
and resource management department shall require replacement in accordance with the arboreal value chart. If on-site replacement
is not feasible, the applicant shall pay the in-lieu fee to the tree replacement fund.
(6)
The following design standards for protected trees shall be adhered to:
a.
Underground trenching for utilities should avoid tree roots within the protected perimeter. If avoidance is impractical, tunnels
should be made below major roots. If tunnels are impractical and cutting roots is required, it shall be done by hand-sawn
cuts after hand-digging trenches. Trenches should be consolidated to serve as many units as possible.
b.
Compaction within the drip line or protected perimeter shall be avoided.
c.
Paving with either concrete or asphalt over the protected perimeter should be avoided. If paving over the protected perimeter
cannot be avoided, affected trees shall be treated and removed for purposes of calculating arboreal values.
d.
Wherever possible, septic systems and/or leach lines shall not be located on the uphill side of a protected tree.
(7)
Security posted for the purpose of insuring the proper construction of public or private improvements shall also include an
amount sufficient to secure any requirements imposed pursuant to this section. In addition, security for potential tree damage
shall be twenty-five (25%) of the amount posted for planned tree replacement. In lieu fees shall be paid prior to recording
any maps. Such security shall not be released until protection requirements, including planting replacement trees, and any
long term maintenance requirements have been satisfactorily discharged. The initial bond amount may be reduced to cover only
the maintenance and replacement of trees after construction is completed.
(8)
The Valley Oak, Quercus lobata, shall receive special consideration in the design review process to the extent that mature
specimens shall be retained to the fullest extent feasible. Valley oaks contribute greatly to Sonoma County's visual character,
landscape and they provide important visual relief in urban settings. On existing parcels created without the benefit of an
accompanying EIR, design review shall focus on the preservation of valley oaks to the fullest extent feasible. Where such
preservation would render a lot unbuildable, partial protection with accompanying appropriate mitigations developed by a certified
arborist shall be incorporated into the project design. In such cases where only partial protection can be achieved, full
replacement in accordance with the arboreal value chart shall be required.
Arboreal value charts.
One of the following charts is to be used for determining arboreal values. The applicant shall indicate at time of application
which chart is to be used. Chart 1 requires analysis to be done only in the development areas (building envelopes, access
roads, etc.) and requires one hundred percent (100%) replacement or in-lieu fees. Chart 2 requires analysis of the entire
site but allows for removal of up to fifty percent (50%) of the arboreal value. Compensation for the loss of greater than
fifty percent (50%) arboreal value will require replacement by using the chart.

Subtract the removed arboreal value from the existing arboreal value. If the removed arboreal value is more than fifty percent
(50%) of the existing, the developer must replace the difference between removed arboreal value and fifty percent (50%) of
existing arboreal value using the arboreal valuations.
*d.b.h. (diameter at breast height, four and one half feet (4 ½′) above ground) can be calculated by measuring the circumference
of the tree and dividing by three point one four (3.14) or pi.
Arboreal valuations.
All trees to be replaced shall be the same native species as that removed unless specific approval has been granted by the
director of the permit and resource management department.
One (1) point arboreal value equals:
(a)
six (6) five (5) gallon trees (can be existing trees on site that are below nine inches (9″) d.b.h. if preservation methods
are part of the development permit); or
(b)
two (2) fifteen (15) gallon trees (the large trees must come from nurseries where they have been irrigated and they must have
on-site irrigation to insure their survival); or
(c)
two hundred dollar ($200.00) in-lieu fee (annual average retail cost can be changed to reflect cost increases).
Two points arboreal value equals:
(a)
twenty-four inch (24″) box tree (the large trees must come from nurseries where they have been irrigated and they must have
on-site irrigation to insure their survival); or
(b)
four hundred dollar ($400.00) in-lieu fee (annual average retail cost can be changed to reflect cost increases).
Replacement trees may be located on residentially zoned parcels of at least one and one half (1-½) acres and on any commercial
or industrial zoned parcel, regardless of size, where feasible. Where infeasible, they may be located on public lands or maintained
private open space. In-lieu fees may be used to acquire and protect stands of native trees in preserves or place trees on
public lands.
(m)
Lot line adjustment. Lot line adjustment applications made pursuant to Chapter 25 of the Sonoma County Code (subdivision ordinance)
which propose to add land to an existing parcel for the purpose of increasing its subdivision potential shall be deemed contrary
to the provisions of this chapter.
(n)
Area design review committees. Where development is proposed on parcels which are subject to area design review committees
which have been created by resolution of the board of supervisors, the following shall apply.
(1)
Prior to issuance of a building permit, the development plan will be reviewed and approved, conditionally approved, or denied
by the director of the permit and resource management department on the basis of site planning as it relates to designated
open space or design policies of adopted general, specific or area plans or other such design criteria as may have been adopted
by the board of supervisors.
(2)
Concurrent with the submittal of the development plan to the director of the permit and resource management department, the
owner shall submit the advisory recommendation of approval, conditional approval or denial of the local design review committee
with jurisdiction over the parcel.
(3)

review committee but shall not be bound by it.
(4)
Decisions of the director of the permit and resource management department approving, conditionally approving, or denying
a building permit pursuant to this section are appealable in accordance with Section 26C-331.
(o)
Year-round farm worker housing. Year-round farm worker housing shall meet the following standards:
(1)
Year-round farm worker housing shall be located on parcels of ten (10) acres or more having an agricultural general plan land
use designation, but may be located on parcels of ten (10) acres or more having a resources a rural development general plan
land use designation provided the parcel is under a Williamson Act contract. Such parcels shall be owned by the applicant.
(2)
Year-round farm worker housing shall be located on parcels having direct access to a county maintained road.
If a private road is to provide such access, the applicant shall file with the permit and resource management department a
written agreement signed by all of the property owners entitled to use such road acknowledging and agreeing to the road's
use as access for the year-round farm worker housing.
(3)
Year-round farm worker housing located on any parcel shall house no more than thirty-eight (38) persons at any time.
(4)
Year-round farm worker housing and support structures shall be set back a minimum of fifty-five feet (55′) from the centerline
of any roadway, sixty feet (60′) from any other property line, forty feet (40′) from any other structure, and forty feet (40′)
from watering troughs, feed troughs, and accessory buildings. Year-round farm worker housing and support structures shall
also be set back seventy-five feet (75′) from barns, pens or similar quarters of livestock or poultry. On parcels adjacent
to a residential zoning district, year-round farm worker housing shall be set back a minimum of five hundred feet (500′) from
the property line adjacent to the residential zoning district.
(5)
Year-round farm worker housing shall have off-street parking provided at the ration of one (1) space per (4) persons housed.

(Ord. No. 5318 § 1, 2001.)
Sec. 26C-323. - General yard regulations and exceptions.
(a)
In the case of a through lot abutting on two streets, no building shall be located so as to encroach upon the front yard required
on either street. This provision may be waived for swimming pools when it is demonstrated to the satisfaction of the director
of the permit and resource management department that the location will not be detrimental to the health, safety or welfare
of adjacent land uses or properties. The director of the permit and resource management department may require a use permit
or signatures from adjacent property owners.
(b)
Any dwelling use to be located in any C district shall provide front, side and rear yards as required in the R2 district;
provided, that this shall not apply to any dwelling use to be located over a commercial or industrial establishment.
(c)
Where irregular lot shapes prevent the direct determination of the area and yard requirements for a lot, the planning director
of the permit and resource management department shall make such determinations as necessary for the administration of this
chapter.
(d)
In any case where an official plan line has been established as part of the street and highway plan, the required yards on
the street side shall be measured from such official plan line, and in no case shall the provisions of this chapter be construed
as permitting any structure to extend beyond any such official plan line.
(e)
In any case where a building setback line or building envelope has been established by a recorded parcel map, final subdivision
map, or the coastal plan, and said setback is different from the setback required by the zoning district in which the parcel
is located, the established building setback line cannot be waived by the director of the permit and resource management department
nor through a variance procedure.
(f)
Protect and encourage agricultural production by establishing a buffer between agricultural production on lands either designated
in one of the three agricultural land use categories in the general plan or lands included within the AR zoning district,
where any such lands abut a non-agricultural land use conducted on land outside the three general plan land use categories.
Generally, buffers shall be defined as a physical separation of one hundred feet (100′) to two hundred feet (200′). These
may be modified based upon topographic feature, a substantial tree stand, water course or similar existing feature. In some
circumstances, a landscaped berm or other man-made feature may enhance the buffer. The requirement for buffer may be modified
after hearing by the advisory agency following a written recommendation by the agricultural commissioner.
Notwithstanding the provisions of Section 26C-350 (non-conforming uses) where the imposition of the buffer creates a non-conforming
condition, expansion or modification of such use may be permitted provided that encroachment into the setback does not exceed
that of the existing structure.
Agricultural production as used herein means either an existing agricultural operation or an agricultural operation that would
be a reasonably anticipated use. No buffer or setback shall be created by the acquisition of a portion of a parcel devoted
to an agricultural operation.
The provisions of this section shall only apply to discretionary permits which are either appealable pursuant to the chapter
or over which the board of supervisors has original jurisdiction.
(g)
In any TP, LIA, LEA, DA, RRD, RRDWA, AR or RR district the required yard standards may be reduced when the director of the
permit and resource management department finds that such reduction(s) are appropriate in light of topography, vegetation,
or unique physical characteristics. In determining such findings, consideration will also be given to visibility from public
roads and adjacent properties. Such reduction shall not result in a front yard of less than ten feet for any garage or carport
opening. The director of the permit and resource management department may require a use permit or signatures from adjacent
property owners.
(Ord. No. 5318 § 1, 2001.)
Sec. 26C-325.5. - Mobile home park standards.
(a)
Compliance with board of zoning adjustments standards generally: All mobile home parks where approved by a use permit in the
R2, or PC district shall be developed in conformance with minimum design and improvement standards adopted by the board of
zoning adjustments.
(b)
Design review: All mobile home parks shall be subject to design review by the director of the permit and resource management
department in accordance with Article XLI and shall meet all provisions of this section; provided, that when a change in design
of any existing mobile home park is determined by the director of the permit and resource management department to be necessary
and such change in design would not allow for full compliance with a provision of this section, the director of the permit
and resource management department shall have the authority to make such a determination as necessary for the administration
of this section.
(c)
Mobile home park lot lines:
(1)
Mobile home park lot lines shall not be created, moved, shifted, or altered except as permitted by this subsection.
(2)
No mobile home park lot lines shall be created, moved, shifted, or altered if the action will place an occupant of a mobile
home space or lot in violation of any mobile home separation or space requirements of this chapter, Part 21 (commencing with
section 18200) of Division 13 of the health and safety code, or any administrative regulation adopted pursuant thereto.
(3)
Applications to create, move, shift, or alter mobile home lot lines shall include the written authorization of the occupant
or occupants, if any, of the mobile home spaces on which the lot lines will be created, moved, shifted, or altered. Written
notice of applications shall be given to interested agencies and all residents of the subject mobile home park. Applications
involving lot lines previously established through the use permit process shall be accompanied by a concurrent application
to amend the applicable use permit and shall be acted upon by the board of zoning adjustments at the same time as the amendment.
(4)
Applications not involving lot lines previously established through the use permit process may be acted upon by the director
of the permit and resource management department if there are no written objections by interested agencies or residents of
the mobile home park. If there are written objections by interested agencies or residents of the mobile home park, the director
of the permit and resource management department shall refer the proposal to the board of zoning adjustments for a public
hearing and decision.
(5)
In order to approve an application to create, move, shift or alter mobile home park lot lines, the finding of the director
of the permit and resource management department or the board of zoning adjustments shall be that the proposal will not, under
the circumstances of the particular case, be detrimental to the health, safety, peace, comfort, or general welfare of persons
residing in the mobile home park or to the general welfare of the area.
(6)
