(Ord. 1016 § 1, 1994)
At the time of adoption of this section, there are two existing
communication transmission facilities which exist within the boundaries
of Specific Plan No. 5: the county communication transmission facility
on the approximate two-acre site west of Lot 31 of Tract 39492 and
the privately owned communication transmission facility on Lot 31
of Tract 39492. The purpose of this section is to provide regulations
for the reasonable continuance, modification and repair of these two
facilities in order to promote compatibility of uses, improve environmental
quality, and protect the public health, safety and general welfare.
Said existing communication transmission facilities shall be subject
to the following standards:
A. Structure
Height. The maximum height of any tower structure shall be one hundred
feet. The maximum height of any accessory building shall be eighteen
feet.
B. Antennae
Modifications. Additions, modifications or relocation of antennae
attachments to the tower facility shall be made in conformance with
the applicable building and engineering codes to the satisfaction
of the city engineer.
C. Expansion of Use. The facilities shall not have additions to, or enlargements or expansions of the tower structure, except to change, upgrade or add antennae pursuant to subsection
B of this section. The facilities may have additions, modifications, strengthening or rehabilitation of the tower structure and/or accessory building(s) subject to the review and approval of the development plan review board pursuant to subsection
F of this section.
D. Reconstruction. If the facilities are damaged or destroyed due to natural and/or unnatural causes, the facilities may be repaired or reconstructed subject to the review and approval of the development plan review board pursuant to subsection
F of this section provided the proposed facilities do not exceed the size, scale or intensity of use as the facilities in existence at the time of destruction of the facilities.
E. Access and Landscaping. To the boundaries of the facility owner's responsibility, the facility owner shall upgrade the existing dirt driveway to an improved, all-weather access to the facility and upgrade existing landscaping to provide sufficient screening of the facility. Said driveway and landscaping shall be installed no later than twenty-four months from the date of adoption of the ordinance codified in this chapter, unless required to be installed sooner pursuant to subsection

(Ord. 1016 § 1, 1994)
No grading permits shall be issued unless the grading plans
have first been approved by the development plan review board and
the planning commission, and it has been found that the grading design
conforms to the provisions set forth in this section. Pre-and post-grading
models may be required at the discretion of the director of community
development.
A. General
Provisions. It is the intent of this specific plan to incorporate
contour grading techniques on slopes exposed to public view and on
lots situated in sensitive topographic uses. This technique shall
be allowed to provide for the placement of permitted uses and for
access to those uses. Storm drainage runoff, where possible, shall
follow its natural drainage course.
B. Contour
Grading Design Intent. Contour grading is a hillside grading technique
which allows for a moderate amount of grading so that the resulting
product resembles natural appearing hillside features. This method
is accomplished by the recontouring of the hillside with slopes and
other features which resemble the natural contours of the hillsides.
The goals of the contour grading concept are as follows:
1. To create a natural appearing hillside development;
2. To provide graded slopes which resemble surrounding natural hillsides;
3. To mitigate the need for massive retaining walls, pylons, stem walls
and house designs that "sprawl" down a hillside;
4. To better site structures in hillside areas;
5. To allow for appropriate landscaping, drainage and architectural
opportunities in hillside areas.
C. Contour
Grading Techniques. The following techniques and characteristics are
features of contour grading and shall be incorporated into the grading
design.
1. Area grading instead of individual lot grading. The intent of contour
grading is to study the slope appearance of the natural hillsides
in the project vicinity, and design a grading scheme which resembles
these natural features. In some cases, this may result in a greater
volume of grading to be performed in order to reach the desired design;
2. Split-level pads instead of flat pads. The intent is to better site
structures into, or along, hillside terrain. Split-level pads or other
creative grading approaches should be used;
3. Pads follow contours. Where level pads are required, the pads should
conform to the direction of the contours when this type of solution
does not conflict with desirable drainage solutions. A series of small
pads that are curvilinear, irregularly-shaped and follow the form
of the hillside are preferable to large, square-shaped pads;
4. Natural-appearing yard areas. Contour grading shall be used to create
pads and yard areas which complement hillside features. Contour grading
shall not be used for the sole purpose of creating flat yard surface
areas. In other words, the desire to have flat yards shall not be
the driving force of a particular grading design. Instead, the hillside
as a whole shall be considered, and flat areas shall only be designed
where they are logical, natural-appearing and of an appropriate size
(i.e., at the base of a hillside or along flat portions of a ridge);
5. Mitigate cliff-hanger developments. Where possible, grading should
be designed such that large structures do not "hang off the edge of
a cliff." Where feasible, grading should provide for the structure
to be nestled into the hillside with a modest setback (i.e., five
or more feet) between the structure and the top of slope. Where a
modest setback is not feasible or appropriate, grading should allow
for strategically located planting areas so that landscaping may be
used to mitigate the perceived mass and bulk of the structure;
6. Smooth transitions on slopes. Graded slopes shall have rounded contour
edges to provide for smooth cuts and curvatures. Contour grading should
soften hard edges left by cut and fill operations where an adverse,
mechanically appearing, visual impact may occur;
7. Varied slope bank gradients. Graded slopes shall be designed to have
a variety of slope bank gradients to emulate natural conditions. For
example, instead of creating a solid 2:1 slope bank, a slope may commence
with a 5:1 gradient near the base and rise with 2:1, 3:1 and 5:1 gradients
to the top of the bank. In some cases, it may be appropriate to provide
1.5:1 slopes;
8. Undulating slope banks. Graded slopes shall undulate to emulate natural
conditions. The intent of contour grading is to employ a variety in
the steepness and configuration of slopes. Contour grading should
be used to blend the graded slopes with the natural undulating character
of the hillside landform;
9. Provide pleasing visual appearance along roadways. Created slopes,
either cut or fill that are adjacent to roadways should be graded
in such a way that an undulating appearance in the graded plane is
provided for a more pleasing visual appearance to the road;
10. Open slope areas. In addition to the designated permanent open space
areas in the development, there should be open slope areas (graded
or natural) on hillside lots which are landscaped with natural vegetation
and provide an appearance of a natural hillside;
11. Avoid excessive flat-planed development. No excessive flat-planed
reconstruction should occur;
12. Mitigate retaining walls, caissons and stem walls. Grading designs
should mitigate the need for massive retaining walls, caissons and
stem walls. For example, with a building site on a steep slope area,
a conventional grading approach may require a ten-foot-high retaining
wall or stem wall to allow for the placement of a structure on the
site; however, a contour grading approach should mitigate this situation
such that the retaining wall or stem wall is eliminated or reduced
to two to three feet in height;
13. Appropriate drainage provisions. Contour grading shall provide for
appropriate drainage and erosion-control provisions;
14. Conceal drainage devices where feasible. Drainage devices should
be placed on a graded slope as inconspicuously as possible. For example,
the downhill lip of brow ditches should be raised to shield the ditch
from public view;
15. Provide erosion control, temporary landscaping and maintenance performance
guarantees for phased developments. Since contour grading often involves
grading more than one lot at a time, there may be instances where
the developer grades lots which the developer does not intend to construct
for some period of time. Hence, if a phased development is proposed,
the developer shall provide appropriate erosion control, temporary
landscaping, and maintenance performance guarantees to ensure graded
areas are properly protected, planted and maintained during all phases
of construction.
D. Grading for Pools and Detached Accessory Structures. In the estate lot area, grading for pools and/or detached accessory structures shall only be permitted where the existing terrain permits such improvements without grading in excess of fifty cubic yards, excluding pool excavation. Such grading shall be in conjunction with design approval by the development plan review board pursuant to the provisions of Chapter
18.12.
(Ord. 1016 § 1, 1994)
Residential buildings and/or structures shall be subject to
the following building height standards.
A. Cluster
Area (Single-Family Attached and Detached) and Standard Areas. No
building or structure shall exceed two stories, as defined by the
Uniform Building Code, or thirty-five feet in height. For the purposes
of this section, building height shall be measured from the lowest,
exposed, point of structure contact with the ground, to the highest
portion of the structure.
B. Estate Area. The single-family estate lots are located on sloping terrain. A third story in excess of the requirements stated in subsection
A of this section may be allowed on the downhill side of the structure. This additional building height and floor area is allowed to provide useable interior floor area for parcels which have limited outside useable area due to the steepness of the parcel. In addition, the third story may provide for architectural design variation to the downhill elevation, and reduce the need for stem wall, pylons and retaining wall construction. Third-story floor areas shall be subject to the following provisions:
1. The third story shall only be allowed on the downhill side of the structure, where the existing slope of the terrain creates the conditions described in subsection
B of this section. The structure shall not exceed two stories, and/or thirty-five feet in height, on the uphill side.
2. The maximum building height of the downhill side shall not exceed
forty-five feet as measured from the lowest point of structural contact
with the ground, to the highest portion of the structure.
3. The third-story floor area shall not exceed six hundred fifty square
feet in size, or twenty percent of the total building floor area,
whichever is more restrictive.
4. The third-story floor area shall be designed in a manner to enhance
the architectural qualities of the structure, and mitigate the perceived
building mass and bulk, as viewed from the downhill side of the structure.
5. The third-story floor area shall include exterior elevation decorative
treatment consistent and complimentary with all other building elevations.
Such decorative treatment may include, but not be limited to, brick,
stone, river rock, wood siding, and similar features.
(Ord. 1016 § 1, 1994)
In the estate area, there shall be a minimum forty-foot separation
between the dwelling and/or attached garage on a lot with the dwelling
and/or attached garage on an adjacent lot.
(Ord. 1016 § 1, 1994)
In the estate area, maximum square footage of structures shall
be as follows:
A. Residential
Units.
1. Estate lots designated as Group One lots in Exhibit B shall have
a maximum of four thousand four hundred square feet of useable, enclosed
areas, excluding a bonus room and/or garage.
2. Estate lots designated as Group Two lots in Exhibit B shall have a maximum of four thousand eight hundred square feet of useable, enclosed areas, excluding a third-story floor area pursuant to Section
18.506.120B and/or garage.
B. Garage.
The maximum square footage of a garage shall be eight hundred fifty
square feet.
C. Accessory
Structure. The maximum square footage of any detached accessory structure,
excluding a swimming pool, spa, open patio, gazebo or deck, shall
be one hundred fifty square feet.
(Ord. 1016 § 1, 1994)
In addition to the standards established by Chapter
18.156, the following standards shall apply:
A. General.
Driveways and drives shall be designed to a grade and alignment that
will provide for a maximum of safety and convenience for vehicular,
emergency and pedestrian use and in a manner which will not interfere
with drainage or public use of the sidewalks and/or street area. Driveways
shall be located and designed to minimize disturbance to natural terrain.
B. Cluster

parking spaces for guests shall be provided for each dwelling unit.
2. Any driveway in excess of one hundred lineal feet and serving more
than two lots shall have a minimum curb-to-curb width of twenty-six
feet.
3. Lots 23, 24, 25, and 26 of Tract 39492 may be required to have a
shared access driveway at the time of development plan review to allow
placement of dwellings further from the street, if deemed appropriate.
(Ord. 1016 § 1, 1994)
The following general development standards shall apply to all
development areas within the specific plan.
A. Walkways.
Design and construction of all walkways shall be subject to the approval
of the city engineer. A pedestrian walkway shall be provided along
Calle Canela and Via Amarillo subject to the approval of the city
