Simi Valley City Zoning Code

CHAPTER 9

30 - General Property Development and Use Standards

9-30.010 - Purpose

This Chapter expands upon the requirements of Article 2 by addressing additional details of site planning, project design, and the operation of land uses, to ensure that proposed development produces an environment of stable and desirable character, is compatible with existing and future development in the vicinity, and protects the use and enjoyment of neighboring properties, consistent with the General Plan and any applicable specific plan.

(§ 5, Ord. 1085, eff. January 6, 2006)

9-30.020 - Applicability

The requirements of this Chapter shall apply to all proposed development and new land uses, except as specified in Chapter 9-72 (Nonconforming Uses, Structures, and Parcels), and shall be considered in combination with the standards for the applicable zoning district in Article 2 (Zoning Districts, Allowable Land Uses, and Zone-Specific Standards), and those in Article 4 (Standards for Specific Land Uses). If there is a conflict, the standards in Article 4 shall control.

(§ 5, Ord. 1085, eff. January 6, 2006)

9-30.030 - Development/Design Considerations

A.

Development criteria. Factors including the following may be considered by the review authority in establishing permit conditions, and in determining appropriate intensity of development and time limitations, including residential densities, for the site of a proposed project:

1.

Freeway corridor development. Development in the freeway corridor between Alamo and Cochran Streets, shall comply with the following requirements:

a.

All accessory buildings shall incorporate design elements, including roof configuration and pitch, materials and colors, similar to the main structure for which the permit was granted.

b.

The use of a flat roof design is discouraged and shall be minimized to the maximum extent feasible.

2.

Screening of mechanical equipment. No roof-mounted air conditioning or heating equipment shall be visible from view from abutting lots, streets, or roadways. This shall be accomplished through the extension of the main structure or roof or other architecturally compatible features.

3.

Roof design and materials.

a.

Roofs (including mansard roofs) shall be built up to a height sufficient to shield mechanical equipment.

b.

Where wood shakes are not permitted because of fire hazard or are requested to be replaced because of damage or age, acceptable substitute materials in lieu of wood shakes, irrespective of Planned Development Permit Conditions relative to roofing materials, shall include barrel tiles, lightweight clay or concrete tiles, molded composites of cement and wood fiber or molded composites of perlite, cement and acrylic fibers and asphalt composition shingle roofing material weighing 300 pounds or more per square (one square equals 100 square feet of roof coverage). Structural support for acceptable substitute roofing materials shall meet Uniform Building Code Standards. Fire retardant treated wood shakes are an acceptable roofing material where no fire hazard exists. Substitution of acceptable materials for wood shakes in compliance with this standard shall be considered equivalent and require no further discretionary review.

c.

Asphalt composition shingles replacing wood shake roofing shall be substantially overlapped to provide a shadow detailing to the roof appearance.

d.

Asphalt composition shingles replacing wood shake roofing shall be of a color resembling natural roofing materials, such as wood and terra cotta tile.

4.

Trash enclosures. Each project shall contain a sufficient number of enclosures to screen bins for collection of discards in compliance with Chapter 9-35 (Recyclable and Discard Material Containers and Facilities) of this Article.

5.

Landscaping. Landscaping should be installed in accordance with the principles as demonstrated in the City's Landscape Design Guidelines.

6.

Walls and fences. Walls and fences shall reflect the overall design theme of the project and consist of the following designs:

a.

Decorative block, such as slumpstone or splitface block, with cap;

b.

Plain block with cap, stuccoed to reflect the general design theme;

c.

Theme pilasters and wrought iron;

d.

Wood fences are permitted only in residential areas. Wood fences shall be of adequate and sound design as determined by the Deputy Director/City Planner;

e.

Chain link fences are not allowed, unless required by Caltrans or the Ventura County Watershed Protection District;

f.

Vinyl fences are permitted only in residential areas and must be installed per the manufacturer's requirements. Vinyl fences shall be constructed with steel-reinforced rails, metal stiffeners, or similar materials to reduce bowing and sustain high wind loads.

B.

Sewage disposal. Sewage disposal for all requested uses and structures shall be provided by means of a system approved by the Department of Public Works.

C.

Fire protection. Dwellings shall comply with all applicable fire protection requirements of the Ventura County Fire Protection District, including all requirements for construction within High Fire Hazard Areas.

The minimum distance between structures on the same lot shall be six feet as measured between the closest exterior walls and/or columns, except that no principal structure shall be placed closer than 10 feet to any other principal structure; if more than one story, minimum distance shall be twenty (20) feet.

C.

Measurement of setbacks. Setbacks shall be measured as follows, provided that whenever this Development Code refers to a setback distance from a street, and the street in question is a public street, the setback shall be measured from the ultimate right-of-way width as shown in the General Plan. See Figure 3-5. In the case of a site with a perimeter wall, the property lot line shall be presumed to be the perimeter wall, unless shown otherwise by a surveyor.

Figure 3-5. Location and Measurement of Setbacks

1.

Front setback. A required front setback shall be measured into a lot from the front property line (or edge of the right-of-way where the property line is at the center of the street), extending the full width of the lot between the side lot lines intersecting the front lot line.

2.

Street side yard setback. A required street side setback shall be measured into a lot from any side property line (or edge of the right-of-way where the property line is at the center of the street) that abuts a street, extending between the front and rear setbacks.

3.

Side setback. A required interior side setback shall be measured into a lot from a side lot line, extending between the front and rear setbacks.

4.

Rear setback. A required rear setback shall be measured into a lot from the rear lot line, extending between the side lot lines intersecting the rear lot line; provided that:

a.

For lots having no defined rear lot line, the rear setback shall be measured into the lot from the rearmost point of the lot depth to a line parallel to the front lot line; and

b.

In computing the depth of a rear setback for any lot abutting an alley, the setback may be measured from the midpoint of the rear alley.

5.

Flag lot setbacks. In the case of a flag lot, the required setbacks shall be measured from the applicable front, rear, and sides of the lot as shown in Figure 3-6.

9-30.090 - Undergrounding of Utilities

Existing and new overhead utility facilities shall be converted to, or installed as, underground utilities in compliance with this Section.

A.

Applicability. No Zoning Clearance shall be issued for any construction of a new structure or land development unless the applicant's plans comply with the provisions of this Section.

B.

Definitions. Definitions of the technical or specialized terms and phrases used in this Section may be found in Article 8.

C.

Requirements for undergrounding. All utilities servicing a new structure or servicing any existing structure located on the same parcel of land as a new structure shall be installed or relocated underground, except as otherwise exempted in this Section. Relocation of existing overhead utility service to an off-site location is not permitted.

Utility lines, such as electric distribution (under 33,000 volts), communications, street lighting and cable television, shall be placed underground by the applicant, who shall make the necessary arrangements with the utility companies for the installation of such facilities. Existing utility poles on the project site shall be removed and undergrounding of all overhead service not directly affecting service to adjacent sites shall be accomplished to the nearest existing off-site pole as determined by the City Engineer. New poles may be set only in special instances where no other feasible solution is available as determined by the utility company.

D.

Exemptions from undergrounding requirements. The following types of facilities are exempt from the undergrounding requirements of this Section.

1.

Poles, overhead wires and associated utility services used for electricity transmission at a nominal voltage of 33,000 volts or higher.

2.

Appurtenant structures and equipment, including surface mounted transformers, pedestal-mounted terminal boxes and meter cabinets.

3.

Temporary poles, overhead wires and associated utility services used or to be used in conjunction with construction projects.

4.

Temporary poles, overhead wires and associated utility services for a temporary use, when a Temporary Use Permit has been issued, and when the permit requires removal of the temporary utility service upon completion of the temporary use.

5.

Public utilities doing work governed by the rules, regulations and tariffs of the California Public Utilities Commission.

6.

Emergency poles, overhead wires, and utility services to be installed and maintained for a period not to exceed 10 days, with the approval of the City Engineer.

7.

Whenever an undergrounding utility district has already been formed or is projected to be formed in compliance with Municipal Code Title 7, Chapter 4, Section 7 4.01 et seq.

8.

Whenever an unreasonable hardship has been established by the Planning Commission in compliance with Subsection F.

E.

In-lieu fee. When a project does not qualify for one of the exemptions listed in Subsection D, above, and the Commission has granted relief from undergrounding in conjunction with a request for construction under Subsection F, an in-lieu fee may be established based on front footage costs estimated by the Southern California Edison Company. The City Engineer shall collect the in-lieu fees and manage and adjust the fees for inflation as deemed necessary.

F.

Hardship waiver - In-lieu fees. If the cost of placing utility services underground is so great as to constitute an unreasonable hardship, the property owner, subject to the undergrounding requirement, may apply in writing to the approving body for relief from the provisions of this Section. The request shall include a detailed description of the overhead utility services proposed to be placed underground and separate itemized cost estimates of construction of the project if the utilities were placed or relocated underground or above ground.

1.

Unreasonable hardship findings. After considering the request for relief, the approving body may grant relief as may be deemed proper under the circumstances, including the imposition of in-lieu fees or the indefinite deferral of the undergrounding requirement. The approving body may grant this relief only if the approving body makes all of the following findings, each of which are supported by substantial facts:

a.

The cost of undergrounding utilities exceeds 20 percent of the total project cost, including all on- and off-site improvements and structures, with valuation to be determined using the currently adopted valuation tables of the Building Official and the Public Works Department;

b.

No new utility poles are to be erected;

c.

There is another overhead utility service in the immediate vicinity which would remain even if no waiver is granted; and

d.

The grant of approval would not be inconsistent with the intent and purposes of this Chapter.

2.

Deferral. The approving body may grant a deferral of the requirements to underground utilities, by requiring a deed restriction to be recorded against the property concurrent with recordation of the final map or prior to issuance of a zoning clearance. The deed restriction will require the current or future property owner to accept any future assessment proceedings for undergrounding the existing onsite overhead utilities. This deferral may only be granted by the approving body if the undergrounding of existing overhead utility services would require the installation of more guy poles than the number of existing utility poles required to be removed. The determination regarding the need for additional guy poles shall be verified by the appropriate utility company.

3.

Appeal of approving body decision. Any decision of the approving body concerning a hardship waiver request under this Section may be appealed by any interested person in compliance with Chapter 9-76 (Appeals), and as follows.

a.

Appeal requirements. The appeal shall contain the following information:

(1)

A detailed description of the overhead utility services proposed to be placed underground;

(2)

A separate itemized cost estimate for: the construction valuation of the project certified by the Building Official; the construction costs of the utilities to be placed underground; and, if applicable, the construction costs of utilities to be relocated above ground; and

(3)

The grounds for the appeal.

b.

Granting of the appeal. Upon consideration of the appeal, the appeal body may grant relief as it may deem proper under the circumstances, including indefinite deferral of the undergrounding requirement. The appeal may be granted if the appeal body is able to make all of the findings of Subsection (F)(1), each of which is supported by substantial facts.
