Article II — Land Uses

In Planning Area Two areas identified for potential development consistent with the goals and objectives of Specific Plan No. 25 are depicted on Exhibit B attached to and located at the end of this chapter.

(Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

• A. The incorporation of the planning area concept into this specific plan creates the opportunity to apply the maximum allowable density and some development standards differently to unique parts of this specific plan. This is beneficial due to varying opportunities for clustered development, access and utilities. The two planning areas are depicted as set forth on Exhibit A located in Section 18.542.630 .

• B. Planning Area One (PA1) consists of three hundred ten plus or minus acres at the southwesterly portion of the specific plan.

• C. Planning Area Two (PA2) consists of nearly seven hundred acres comprising the remainder of the specific plan.

• (Ord. 1201 § 1, 2011; Ord. 1236 § 1, 2016)

• A. The maximum allowable density for Planning Area One shall be 0.225 dwelling units per acre, not to exceed sixty-five dwelling units.

• B. The maximum allowable density for Planning Area Two shall be as shown in the following table:

• C. Achievement of the maximum development intensity cited above is not guaranteed; the actual yield of any development is to be determined based upon:

  1. Site-specific physical characteristics;

  2. The need for mitigation or avoidance of impacts to biological habitats;

  3. The environmental sensitivity of proposed site design, grading and type of construction;

  4. Available on-site and off-site access and circulation; and

  5. The ability of the proposed project to avoid impacts on other properties.

• D. Individual developments within Specific Plan No. 25 must be consistent with the general policies and actions contained in the General Plan. It is specifically acknowledged that a project that meets applicable development policies might not achieve the maximum development intensity for the site.

• E. Within the Specific Plan No. 25 area, there are existing lots of record that exceed the maximum development densities cited above. For these parcels, one single-family dwelling unit may be permitted without compliance with maximum allowable density and minimum lot size but subject to all other regulations and requirements of this specific plan.

• (Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

Accessory uses in Planning Areas One and Two of Specific Plan No. 25 are as follows:

• A. Home occupations, in accordance with the provisions of Section 18.184.010 ;

• B. Household pets, in accordance with the provisions of Section 18.20.060 ;

• C. Animal keeping, in accordance with the standards set forth in Sections 18.28.020(C) , 18.28.050 and 18.28.060 , as applicable;

• D. Horsekeeping, in accordance with the provisions of Section 18.542.380 ;

• E. Public utility facilities, as approved by the director of planning;

• F. Other uses similar to those stated which the director of community development finds consistent with the spirit and intent of this specific plan.

• (Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011; Ord. 1324, 6/10/2025)

Temporary uses in Planning Areas One and Two of Specific Plan No. 25 are such uses as are permitted pursuant to Section 18.196.050.

(Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

Article III. Development Standards

This article is intended to provide standards for development of all residential and open space land uses within the specific plan area. Any development standards which are applied differently between Planning Areas One and Two are specifically identified. Where no distinction is made the development standards are applied the same throughout the specific plan. (Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

The minimum lot size shall be as set forth in this section. The establishment of minimum lot sizes within Specific Plan No. 25 is intended to set minimum lot size only. The density of new development, whether it is within a clustered or a nonclustered project, shall not be permitted to exceed the maximum density allowed by the San Dimas General Plan. A clustered development consists of a minimum of four lots grouped together sharing a common access and being similar in lot size.

• A. The minimum lot size within Planning Area One shall be as follows:

  1. One-half acre in a clustered land division;

  2. Two acres in a nonclustered land division.

• B. The minimum lot size in Planning Area Two shall be as follows:

Average natural slope < twenty percent:

Two acres in a nonclustered land division;

One acre in a clustered land division.

Average natural slope twenty to forty-eight percent:

Within Development Feasibility Zones:

Five acres in a nonclustered land division;

One acre in a clustered land division.

Outside of Development Feasibility Zones:

Twenty acres in a nonclustered land division;

Two acres in a clustered land division.

Average natural slope > forty-eight percent:

Forty acres in a nonclustered land division;

Two acres within a clustered land division.

  2. Within Planning Area Two, on a parcel where a minimum of four parcels are allowed, not more than one parcel may be approved for a two-story structure. Such structures shall not exceed thirty-five feet in overall height. A visual analysis shall be required to demonstrate that the additional height will not increase visual intrusiveness. Any other parcels created in the future shall include a deed restriction prohibiting two-story structures.

• B. On sloping lots building height shall be determined as follows:

  1. Downhill Lot. An overall maximum height of twenty feet, except for approved two-story designated lots, is permitted, as measured from finished grade, from the minimum front

setback extending towards the rear of the lot.

Setbacks for accessory structures shall be as established by the director of community development or designee, but no less than forty feet to the side or rear yard property line but a lesser minimum setback may be reviewed and approved by the director of community development or designee if warranted by topographic conditions or to otherwise comply with the intent of standards set forth in this specific plan.

• (Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011; Ord. 1324, 6/10/2025)

All site plans shall be in compliance with the following standards:

• A. The visual intrusiveness of new development shall be minimized.

• B. Site design shall utilize varying setbacks, structure heights, innovative building techniques, and retaining walls to blend structures into the terrain.

• C. Lot and site design shall consider building separation to facilitate privacy between residential structures.

• D. Site design shall allow for different lot shapes and sizes, as well as the provision of split development pads, with the prime determinant being the natural terrain.

• E. Flag lots shall be allowed in areas where it is demonstrated that the end result is the preservation of natural topography by minimizing grading.

• F. Structures shall be sited in a manner that will fit into the hillside's contour, except in an approved clustered development, and relate to the form of the terrain; retain outward views while maintaining the natural character of the hillside; preserve vistas of natural hillside areas and ridgelines from public places and streets; preserve existing views; and, allow new dwellings access to views similar to those enjoyed from existing dwellings (see figures below).

==> picture [442 x 383] intentionally omitted <==

• G. Clustered development is encouraged as a means of preserving the natural appearance of the hillside and maximizing the amount of open space. Under this concept, dwelling units are grouped in the more level portions of the site, while steeper areas are preserved in a natural state as "no building" areas.

  1. Clustered development must preserve open space in its natural state. Adequate legal provisions shall be made to ensure the preservation of open space areas in perpetuity.

  2. When viewed from outside the northern foothills area from the south, southwest and southeast, clustered subdivisions are to have no greater visual impacts than would a nonclustered development, except for required reduction in lot size and closer proximity of home sites.

• H. Primary and secondary ridgelines are identified on Exhibit C attached and part of this chapter and are subject to the following standards.

  1. Primary ridgelines shall be protected from any construction activities including, but not limited to roads, structures, water tanks, antennae, utilities, and other structures or facilities so as to maintain a natural skyline (see figure below). Where the only feasible location for a structure is on a primary ridgeline, the structure shall be sited and designed to minimize any visual intrusiveness.

==> picture [370 x 174] intentionally omitted <==

2. New parcels which have as their only feasible building site a primary ridgeline shall not be created. Where the only feasible building site within an existing parcel is on a primary ridgeline, the structure shall be sited at the lowest possible elevation on the site, and along the least visible portion of the ridge upon which a structure can feasibly be constructed.

3. Where development is proposed to occur adjacent to a primary ridgeline (a ridge which is visible against the sky as viewed from a public street), it should be set back a sufficient distance so as to be located below the ridgeline. The intent of this requirement is to maintain a natural skyline (see figure below).

==> picture [421 x 122] intentionally omitted <==

4. Planting shall be used along re-contoured secondary (non-skyline) ridges to recreate a natural silhouette, and to act as a backdrop for structures.

Trees shall be planted to create a continuous linear silhouette since gaps in the planting will not give the desired effect (see figure below). Subject to preserving views out; not more than fifty percent.

• (Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

In addition to the standards established by Chapter 18.156 , the following standards will apply:

• A. General. Driveways and drives shall be designed to a grade and alignment that will 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 street areas. Driveways shall be located and designed to minimize disturbance to natural terrain.

• B. A minimum of two off-street parking spaces within a fully enclosed garage shall be provided for each dwelling unit. In addition, four off-street parking spaces for guests shall be provided for each dwelling unit. Off-street guest parking may be reduced where it is found that sufficient onstreet parking is available or excessive grading would be necessary to create the off-street guest parking.

• C. Driveways shall have a minimum width of sixteen 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 onsite costs of development. Driveways which serve more than one lot, as well as diagonal driveways running along contour lines, are encouraged as a means of reducing unnecessary grading, paving and site disturbance. These arrangements shall be encouraged (see figure below).

==> picture [304 x 411] intentionally omitted <==

Driveways can reduce grading

• (Ord. 1106 § 1, 1999)

Plans delineating access to the subject site and areawide circulation shall be required and shall be in compliance with the following standards.

• A. Street Design Standards. Street designs shall comply with the following standards:

  1. Roadways within Specific Plan No. 25 shall provide for minimum safe passage of two cars along a paved road section, except in limited circumstances and as approved by the planning director and city engineer.

  2. Street widths shall conform to the following minimum street sections. On-street parking shall be prohibited unless deemed safe or unless parking turn-outs are provided.

==> picture [421 x 240] intentionally omitted <==

==> picture [421 x 179] intentionally omitted <==

3. Streets shall follow the natural contours of the hillside to minimize cut and fill, where feasible (see figures below).

4. Streets may be split into two, parallel one-way streets, thereby effectively functioning as a two-way street with a median, in steeper areas to minimize grading and blend with the terrain (see figures below).

==> picture [421 x 177] intentionally omitted <==

==> picture [421 x 555] intentionally omitted <==

5. Cul-de-sacs or loop roads are encouraged where necessary to fit the terrain.

6. On-street parking and sidewalks may be eliminated, subject to city approval, to reduce required grading.

• B. Roadway Curve and Grade Standards. Roadway grades and curves should accommodate safety and emergency vehicles.

  1. Existing roadway grade standards shall be applied to all proposed subdivisions and parcel maps. However, the planning director and city engineer may grant exceptions to existing roadway standards for grades and curves where, in their judgment, existing or future access cannot reasonably meet such standards. These exceptions are to be limited to

providing access to a single-family dwelling on an existing lot of record along roadways which will ultimately serve a maximum of four dwellings, based on the maximum allowable density in the General Plan, and where not providing such an exception would effectively preclude access to an existing lot of record.

2. Where the planning director and city engineer grant an exception to roadway grade standards, owners whose land is served by such a roadway will be required to provide adequate assurance that the roadway will be kept properly maintained at all times. In addition, such landowners will be required to record a deed restriction which prohibits further subdivision of the property without meeting roadway grade standards and provides an acknowledgment of this special circumstance. Such owners will also be required to indemnify the city or any other service provider against any liability regarding emergency or nonemergency vehicle access.

• C. Circulation Standards. Roadway improvements to provide access to parcels shall not adversely affect other properties through extensive grading, flood control facilities, or any other type of construction and/or requisite support infrastructure.

• D. Reductions in Minimum Roadway Standards. In conjunction with the review of a development proposal, consideration may be given to reducing certain specified roadway standards pursuant to the following:

  1. Within the upper elevations of the northern foothills area, a further reduction in required roadway width may be permitted for private roadways which will ultimately serve a maximum of four dwellings, based on the maximum allowable density permitted by the General Plan, and where not providing such a reduction would effectively preclude access to an existing lot of record. For such roadways, roadway standards may permit a curb-tocurb width which does not allow for passage of two vehicles (minimum sixteen feet, measured edge-to-edge) for a distance of up to one hundred fifty feet in any one segment.

     • a. Where such a reduction in roadway width is permitted, owners whose land is served by such a roadway shall be required to provide adequate assurance that the roadway will be kept properly maintained at all times. In addition, such landowners will be required to record a deed restriction which prohibits further subdivision of the property without meeting roadway width requirements, and provides an acknowledgment of this special circumstance.

Overhead utilities (e.g., electrical, telephone, etc.) should only be permitted within the right-ofway of roadways connecting development areas; to serve development of a single dwelling unit on an existing lot of record; and within the rights-of-way of roadways where all lots are five acres in size or greater.

• B. In cases where aboveground utilities are permitted within the right-of-way of a roadway, connections to individual dwellings shall be underground. Utilities shall continue to be underground within subdivisions and parcel maps along roadways serving parcels smaller than five acres, as currently required. Where overhead utilities are permitted, their adverse visual impact on surrounding properties is to be mitigated through sensitive placement.

• C. Clear cutting of vegetation for an overhead utility corridor shall not be permitted.

• D. Plans shall indicate location of utilities and utility easements serving or intending to serve the proposed structures. The approvals may require or otherwise facilitate the appropriate sizing of utilities to serve other parcels in the area and the provision of access to those utilities by the same parcels.

• (Ord. 1106 § 1, 1999)

Municipal water or on-site wells and water storage shall be available for each development, including construction of a single-family house on a lot of record. The use of on-site wells and water storage will be considered where adequate flow and storage capacity for daily, peak day, peak hour, and minimum fire protection needs can be provided. Where such on-site well and water storage is permitted, the owner whose land is so served will be required to provide adequate assurance that the well and storage facility will be kept properly maintained at all times. In addition, such landowners will be required to record a deed restriction which prohibits further subdivision of the property, and provides an acknowledgment of this special circumstance. Such owners will also be required to indemnify the city or any other service provider against any liability regarding water service and availability of fire flow.

(Ord. 1106 § 1, 1999)

Municipal sewage collection or on-site sewage disposal shall be available for each development, including construction of a single-family house on a lot of record. On-site sewage disposal, if provided, shall comply with applicable health regulations. (Ord. 1106 § 1, 1999)

Article IV. Architectural Guidelines

• A. The purpose of the architectural guidelines is threefold:

  1. To provide the city with the necessary assurances at the time of adoption of Specific Plan No. 25 that the community will develop in accordance with the quality and character proposed in this chapter;

  2. To provide policy guidance to builders, residents, engineers, architects, landscape architects, and other design professionals in order to comply with the standards contained herein;

  3. To provide guidance to the review authority pursuant to Chapter 18.12 of this title in the subsequent review of building plans as noted in the plan review and plan disposition procedures.

• B. The city council may, by resolution, adopt additional design guidelines to illustrate the purpose and intent of this article.

• (Ord. 1106 § 1, 1999; Ord. 1324, 6/10/2025)

Architectural statements should convey a feeling or impression rather than standing out as any particular style. Each residence should convey its own blend of building forms, textures and site relationships. There is not one particular style but rather an atmosphere that should be the result of building designs, sensitively integrated with the site, the topography and character of the property. Desirable building design goals include, but are not limited to, the following:

• A. The creation of a human scale of buildings such that the structures do not appear to be monumental in size or visual scale;

• B. The promotion of controlled variety by the use of such techniques as breaking up long wall surfaces and roof lines into staggered masses, employing natural or highly textured materials on buildings or walls and employing balconies to provide useable outdoor space as well as visual relief;

• C. Variation in roof forms by occasional turning on end, the addition of architectural details, or the use of differing heights of roof peaks;

• D. Avoidance of conflicting or "hodgepodge" effects in style or materials within planting areas;

• E. The overall scale and massing of structures shall respect the natural surroundings and unique visual resources of the area by incorporating designs which minimize bulk and mass, follow natural topography, and minimize visual intrusion on the natural landscape.

• F. Building forms shall be scaled to the particular environmental setting so as to complement the hillside character and to avoid excessively massive forms that fail to enhance the hillside character (see figures below).

==> picture [442 x 410] intentionally omitted <==

• G. Building facades shall change plane or use overhangs as a means to create changing shadow lines to further break up massive forms.

• H. Wall surfaces facing towards viewshed areas shall be minimized through the use of single story homes, single story dwellings placed on split pads, setbacks, roof pitches and landscaping.

• I. Roof lines and elements shall reflect the naturally occurring ridgeline silhouettes and topographical variation, or create an overall variety, that blends with the hillside (see figures below).

==> picture [442 x 450] intentionally omitted <==

• J. Architectural style, including materials and colors, should be compatible with the natural setting. The use of colors, textures, materials and forms which will attract attention by not relating to other elements in the neighborhood is to be avoided.

• (Ord. 1106 § 1, 1999)

Buildings and other improvements should be appropriate in mass and scale to the site on which they are placed. The site and its relationship to other structures, scenic values, climatic orientation and topography should be dominant factors in the design or orientation of structures on each site. (Ord. 1106 § 1, 1999)

Landscape design and proper use of plant materials can dominate the total visual image presented by the buildings. Landscape materials should include native materials. The design of fencing and exterior lighting is an integral part of the landscape design process.

(Ord. 1106 § 1, 1999)

The building and its elements should be unified in textures, colors and materials to provide an order and coherence, not only with themselves, but also with the surrounding environment or natural setting. Nature provides a strong coherent order without monotony that includes symmetrical, asymmetrical, linear and curvilinear forms, and rough and smooth textures. The design of improvements should complement this natural site order in form, texture and color. (Ord. 1106 § 1, 1999)

Article V. Plan Review and Disposition

Before any grading or construction is undertaken on any lot or parcel within the Specific Plan No. 25 area, development plans shall be reviewed and approved pursuant to Chapter 18.12 of this title. (Ord. 1106 § 1, 1999; Ord. 1324, 6/10/2025)
