San Dimas Municipal Code § 18.536.200 Landscaping

This article is intended to provide for development of all residential and open space land uses within the specific plan area.

(Ord. 870 § 1, 1987)

Each single-family residential structure (dwelling) together with any accessory structures shall be located on an individual residential building site (lot). There shall be no more than one single-family dwelling per residential lot. No lot established by this specific plan may be further subdivided for the purpose of creating a buildable residential lot.

(Ord. 870 § 1, 1987)

The design intent is to provide buildable home sites with minimum lot sizes of five thousand five hundred square feet, permitted in conjunction with permanent preservation of open space.

A. Lot Sizes. Lot sizes shall be no less than five thousand five hundred square feet, the average lot size being approximately six thousand four hundred square feet.

B. Lot Width and Depth. Lot width and depth may vary, however, each dwelling unit located on an individual residential building site (lot) will meet the required front, rear and side yard setbacks as set forth in this specific plan.

C. Front Setback. Minimum front setback shall be twenty feet from the front property line.

D. Side Yard Setbacks.

1. The minimum required side yards for detached single-family residential development shall be five and eight feet, with an eight-foot side yard being provided on the driveway side of the lot. On corner lots, the side yard adjacent to the street shall be a minimum of ten feet.

2. Setbacks for accessory structures shall be five feet to the side or rear yard property lines.

E. Lot depth as measured at the rear building line shall be no less than twenty feet for all lots.

F. Residential Unit Size. Each residential unit shall have a minimum of one thousand six hundred square feet of living area, not including patios, porches or automobile parking areas.

(Ord. 870 § 1, 1987; Ord. 1324, 6/10/2025)

No building or structure shall exceed two stories or thirty-five feet in height, whichever is less, as defined by the Uniform Building Code.

(Ord. 870 § 1, 1987)

In addition to the standards established in Chapter 18.156, the following standards shall apply:

A. General. Driveways and drives shall be designed to provide the 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 areas.

B. A minimum of two off-street parking spaces within a fully enclosed garage shall be provided for each dwelling unit. In addition, two off-street parking spaces for guests shall be provided in the driveway for each dwelling unit.

C. Driveways shall have a minimum depth of twenty feet and a minimum width of sixteen feet, except for turn-in driveways, which shall have a minimum width of twelve feet unless modified to preserve natural terrain pursuant to the plan disposition procedure.

D. The occasional use of common driveways serving two or more residences can drastically reduce the potential monotonous repetition of driveways as well as reduce grading and the on-site costs of development. This arrangement shall be permitted.

E. One recreation vehicle parking stall shall be provided for each dwelling unit. The recreational vehicle parking stalls will be located in the common area except for those units with a twelve-foot side yard setback. If a unit has a twelve-foot side yard setback on the garage side of the lot, the side yard will be counted as the recreational vehicle parking area. No structure, pool, mechanical equipment, or similar installation shall be permitted to encroach within any portion of the twelve-foot setback area from the rear of the house forward to the street. The recreational vehicle parking stalls located in the common area will be for the exclusive use of the residents within the development.

(Ord. 870 § 1, 1987)

Street designs shall be in accordance with the city. In addition, the minimum horizontal radius for local residential streets shall be one hundred feet. The minimum right-of-way width for local residential streets shall be forty-six feet, with thirty-two feet of paving and parking permitted on one side. All street sections shall be shown on the tentative tract map. Modifications to the standards in this section shall be as approved by the city engineer.

(Ord. 870 § 1, 1987)

A. Design Concept. Landscaping will be incorporated in specific perimeter areas to eliminate negative visual impacts both on and off the site through selective screening. Locations of key entries, visual screening, and conceptual design shall be required as part of the conceptual landscape plan.

B. Landscape Plan and Plant Materials List.

1. Prior to the issuance of building permits, a conceptual landscape plan for all developer-installed landscape areas shall be submitted to the director of community development for review and approval;

2. A final landscape plan shall be approved by the director of community development. The landscape plan shall clearly indicate general location, size and species of plant materials;

3. In addition, a suggested plant material list for use by individual homeowners in their selection of plant materials shall be submitted.

C. Landscaping of Individual Properties. The individual homeowners are required to have their property landscaped within six months from acquiring the property.

D. Landscaping of Common Areas. Innovative and abundant landscaping shall be provided throughout the common areas. Except for required walks, drives, paths, and common area facilities provided by this specific plan, all of the common areas shall be landscaped.

E. Fire Prevention. In order to reduce potential fire hazards, existing fire prone plant materials shall be eliminated along main roads or sprinkled or otherwise irrigated so as to reduce their fire prone characteristics. Landscape material used shall be selected for its fire retardance characteristics. All plant material shall meet with the requirements of the Los Angeles County fire department.

F. The development plan shall provide for the protection of mature trees (trunk diameter of four inches or larger) in place. In the event that the review authority pursuant to Chapter 18.12 of this title determines protection in place is feasible, then one of the following shall occur: oak trees shall be relocated on site, all other trees may be removed, but a tree of like species and size shall be installed elsewhere on site.

(Ord. 870 § 1, 1987; Ord. 1324, 6/10/2025)

Prior to installation of any sign, a sign program shall be submitted to the review authority pursuant to Chapter 18.12 of this title for review and approval. The sign program shall show signs drawn to scale, dimensioned and easily readable, containing, but not limited to, the following:

A. General location and bulk of major community identification or directional signs;

B. Location of major community components such as streets, permanent open space, entry statements and development areas;

C. Model complex signs.

(Ord. 870 § 1, 1987; Ord. 1324, 6/10/2025)

All public streets shall be provided with a level of street lighting designed to protect the health, safety and welfare of those living within the development. Street lights shall be mounted on city standard electroliers. Prior to the installation of any lighting or other developer-installed community lighting other than street lighting, a general lighting plan shall be submitted to the planning division for review and approval.

(Ord. 870 § 1, 1987; Ord. 1324, 6/10/2025)

A. Walls and fences facing public roadways shall be a minimum of six feet in height and be built in order to insure the health, safety and welfare of the residents of this development. Walls and fences to the sides and the rear of the property shall be at the property line, in order to prevent the creation of abandoned areas. This rule shall not apply to interior division fences used for such purposes as swimming pool security or equestrian facilities.

B. A community fencing plan shall be submitted to the planning division for review and approval. The community fencing plan shall clearly indicate the location, height, type of materials and color selections to be utilized for fencing. Areas prohibited from fencing shall be indicated on the community fencing plan. Homeowner-installed fencing shall be per the specific plan and must be reviewed and approved by the planning division.

(Ord. 870 § 1, 1987; Ord. 1324, 6/10/2025)

The developer shall not be required, pursuant to this section, to install patio or deck areas. However, any persons wishing to install a patio or deck area shall do so in accordance with a development plan approved by the city.

(Ord. 870 § 1, 1987)

A. The site has been analyzed with reference to the requirements of the city. This is an initial analysis and is attached to this chapter as Exhibit C.

B. Ambient noise levels in the project area are primarily the result of traffic on adjacent streets and the Route 30 freeway. The result of the initial acoustical study on this development states that an eleven foot sound barrier is needed along the south side of the site from Lot 11 to Lot 27. If the eleven foot wall is built, the first floor level rooms are satisfactory with standard construction, while second floor level noise will most likely require modification in the form of glazing upgrades ranging from dual to laminated glass.

C. Ideally, noise barriers incorporate the placement of berms, walls or a combination of the two in conjunction with appropriate landscaping to effect an aesthetically pleasing environment. Thick landscaping (without deciduous plants) should be specified to reduce the visual impact of the barrier and retain the rural ambience.

D. Noise standards are implemented at various points in the planning and design of a development. At the site plan review level, proper structure arrangement and orientation can be evaluated and approval conditioned upon setbacks, landscaped buffers, etc., and resolve noise difficulties. At the subdivision or tentative tract map level, detailed noise abatement requirements such as architectural design, acoustic construction techniques and the erection of noise barriers are established as deemed necessary.

(Ord. 870 § 1, 1987)

A. All utilities, including CATV cable to serve the residential units in this development shall be installed underground.

B. The sewer will be extended easterly from Amelia Avenue to the easterly boundary of the property and will serve the units on the interior streets.

C. Water will be provided by Southern California Water Company.

D. Gas will be provided by Southern California Gas Company.

E. Electricity will be provided by Southern California Edison.

(Ord. 870 § 1, 1987)

A. The Bonita Unified School District has analyzed the student generation from each housing unit by the elementary level (kindergarten through grade five), intermediate (grades six through eight), and high school (grades nine through twelve). The actual number of students enrolled in the public schools in the Bonita Unified School District from new housing starts is used to determine that factor.

B. The data reflects a slight increase in the elementary (kindergarten through grade five) level, and a fluctuating factor in the intermediate (grades six through eight), and high school (grades nine through twelve) levels.

(Ord. 870 § 1, 1987)

A homeowners owner's association will be developed to maintain and manage the common areas (i.e. pool, spa, equestrian facility, etc.). The homeowners will pay a flat fee for this maintenance and management.

(Ord. 870 § 1, 1987)

A. One paddock or box stall shall be provided for each dwelling unit and shall be for the sole use of the residents of the tract.

B. The equestrian center will be utilized for passive equestrian activities. Only those homeowners renting paddocks on the premises may participate in any organized events. No other organized activities will be permitted.

C. The common areas (i.e. pool, spa, equestrian facility, etc.) will be for the sole use of the residents within the tract.
