Hazardous waste handling, transportation, recovery, and disposal shall be regulated according to Federal Resource Conservation and Recovery Act, 1976; California Water Code, Division 7, Chapter 5; California Health and Safety Code (Division 20, Chapter 6.5, Hazardous Waste Control, Sections 25100 - 25240); California Administrative Code (Title 22, Division 4, Chapter 30, Environmental Health) and the City of Yucaipa Hazardous Waste Management Plan.

Solid waste disposal. Solid waste disposal shall be regulated as per City Ordinance No. 119 and California Government Code, Title 7.3, which relates to solid waste management. Also involved is Federal Resource Conservation and Recovery Act of 1976, P.L. 94-580, which provides minimum standards and regulations for solid waste and hazardous waste management and recovery (recycling). The Public Works Director shall be the enforcement agent.

The standards, guidelines and procedures established by this Chapter shall apply to all lands lying within the corporate limits of the City of Yucaipa that are within the Hillside Overlay District as designated by the City of Yucaipa General Plan Hillside Overlay District Map and shall apply to all prominent Ridgelines as designated by the City of Yucaipa General Plan Hillside Overlay District Map, its sphere of influence as determined by LAFCO, and its overall planning area as determined by the General Plan of the City of Yucaipa. All properties seeking annexation, or preapproval of projects pending annexation to the City will be evaluated according to these standards, guidelines and procedures.

The requirements and guidelines portions of these standards for ridgeline preservation and hillside development are presented in two separate reports. The requirements portion shall apply to all projects in hillside areas with average slopes over 15%. The guidelines portion consists of recommendations; however, they shall be enforced based on the significance of individual projects at the discretion of the Community Development Director. The requirements and guidelines build upon and enhance the goals, objectives and General Plan policies of the City of Yucaipa.

Hillside classifications have been determined to identify significant categories relative to hillside development. These categories have been classified in terms of landform types with respect to different slope categories, as follows:

Slopes of 0—6% are essentially flat land, normally posing no major restrictions to development, except in terms of landscaping and maintenance for the small amounts of slopes created. Slopes of 6.1—15% are not suitable for freeways and major arterials, but flexible as to local road orientation and site layout. There are generally no significant constraints associated with this category, but it is more restrictive than flat land. Development in areas with slopes of 15.1% and above shall require Hillside Development Review. Hillsides of 15.1—20% slope are significantly affected in terms of read alignment in that roads will normally be required to parallel contours. More significant grading is required to create flat pad areas, and the orientation of site planning, such as orienting pads parallel to contours to avoid significant side splits or a saw tooth effect on graded pads, begins to be restricted in terms of access and the ability to grade flat sites. In steep hillside areas of 20.1—30% slope, the required quantities of earthwork necessary for grading to create flat pads increases dramatically, as does the significance of view opportunities and visual prominence. In mountainous areas with slopes of 30.1—40%, both access and the ability to create pads using 2:1 slopes are severely restricted. Flat areas and roads are difficult to create, making access a problem. In rugged mountain areas with slopes of 40.1% or greater, development is prohibited. Without the use of retaining walls, access is very difficult and the grading of pads on side slopes of 40.1% or greater is virtually impossible without massive grading that would involve cutting hilltop areas and filling the valleys.

Any Tentative Parcel Map or Tentative Tract Map in the vicinity of or affecting ridgeline areas shall be required to perform a view analysis depicting before and after conditions. Views from a minimum of three (3) selected vantage points showing a precise depiction of the potential visual impacts of the proposal shall be presented to the Planning Commission. The technology may incorporate the use of a three-dimensional computer model or photographs incorporating a height reference (either reference poles or chalk lines) of the proposed development in order to display the impact of development on ridgeline views.

Alternatives which staff may require for ridgeline preservation are:

The average cross slope formula for calculating average slopes for any given site shall be as follows:

Where there is a dramatically different landform character in the topography of any one site, the site may be divided into several distinct areas and average slope calculated separately, at the discretion of the Community Development Director.

The slope and natural open space relationship below is used to determine natural open space dedication requirements for development projects based on the slope of the land. One column defines the percentages of slope within a project that are to be categorized. The other column indicates the proportion of each slope category that must be left as natural open space.

The relationship is designed so that as the steepness of the land increases, the open space requirement increases. This encourages development on rugged environmentally sensitive terrain to be concentrated or intensified in the most appropriate areas of the site. It does not necessarily, however, prohibit development on steep slopes, nor does it necessarily reduce the permitted density.

Other public health, safety or welfare considerations could also increase the open space requirements for a project.

The method of calculating the percent slope of any piece of land involves plotting the land on a topographic base map and dividing the vertical rise between contours by the horizontal distance between the same contours, multiplied by 100. A slope map shall be prepared and submitted with any residential development application. The slope map shall include the following information:

The amount of land to be left in natural open space for any given project is computed by multiplying the number of acres of the project area within each slope category by the required percentage of natural open space for that category. The totals for each category are then summed to yield the total natural open space requirement for the project.

Building pads in hillside areas shall have a minimum dimension of 60 feet in width measured at the building setback line.

Manufactured Slopes shall not exceed a slope ratio of 2:1 (cut or fill).

The maximum slope height shall be 30 feet between pads or between roads and pads or between two roads, or a maximum of 30 feet of cut and fill area which ties into natural grade for a road or a pad. All slopes will be rounded at the top and the toe of the slope to a minimum of 15 feet radius.

Retaining walls in the back of the pad on a lot shall be a maximum of six feet (6') in height. Retaining walls in the side yard of a lot shall be a maximum of four feet (4'). Retaining walls may be used with planters in between the walls to soften the effect within a minimum horizontal spacing of three feet (3'). Adjacent to roadways, retaining walls shall be a maximum of four feet (4') high, or a total of six feet (6') if two (2) three-foot (3') walls are used in combination with a minimum horizontal spacing of three (3) feet.

At the discretion of the Community Development Director the Guidelines for roads depicted in the Hillside/Ridgeline Development Manual shall apply.

All projects shall be reviewed by the Community Development Director to determine if they are subject to the criteria defined in the Design Guidelines section of the Hillside/Ridgeline Development Manual.

Building envelope/setback and height.

Fencing. Privacy walls and fences, not exceeding six feet (6') in height, are permitted adjacent to structures in order to provide a private outdoor area. All fences which are adjacent to or visible from public roads or major public spaces shall be decorative masonry or other approved materials with a preference to use of indigenous rock and colors of materials which blend with the surrounding landscape.

Development shall be constructed in such a manner so as to reduce the potential for spread of brushfire through consideration of the following:

Residential developments shall be constructed with adequate water supply and pressure for all proposed development in accordance with standards established by the Fire Marshal.

A permanent fuel modification area shall be required around development projects or portions therefor that are adjacent or exposed to hazardous fire areas for the purpose of fire protection. The required width of the fuel modification area shall be based on applicable building and fire codes and a Fire Hazard Analysis Study approved by the Fire Marshal.

Fuel modification areas shall incorporate soil erosion and sediment control measures to alleviate permanent scarring and accelerated erosion.

The following standards complement those contained in the Grading Manual and define basic grading techniques which are consistent with adopted ordinances and which avoid unnecessary cut and fill. Limitations on project grading amounts and configurations will be decided on a case-by-case basis.

The following standards define access criteria:

The following standards complement those contained in the Grading Manual.

Intent. The purpose of the Citywide Design Guidelines is to implement General Plan policies regarding the advancement of the visual quality of the community, and to ensure that new projects provide high quality design and architecture by providing clear and concise direction for the renovation of existing buildings and the construction of new buildings.

Locational requirements. The Design Guidelines shall be applied in the City of Yucaipa for all Land Use Districts.

Intent. The landscape development standards, procedures and guidelines established by this Chapter are meant to be complementary to those found in the City of Yucaipa's standard project Conditions of Approval, as well as the landscape provisions found in the City's Development Code, including Division 8, Specific Use Design Standards, and Chapter 4, Water Conservation, under Division 10, Soil and Water Conservation.

Applicability. The landscape requirements shall apply to all new development projects in the City of Yucaipa.

Duty to maintain. All projects shall maintain their approved landscaping.

Compost. Compost at a rate of a minimum of 4 cubic yards per 1,000 square feet of permeable area shall be incorporated to a depth of six (6) inches into the soil. Soils with greater than six percent (6%) organic matter in the top six (6) inches of soil are exempt from adding Compost and tilling. Compost procurement shall be coordinated with the City and its Purchasing Policies and Procedures related to SB 1383 for eligible compost and State regulation 14 CCR Chapter 3.2 of Division 7.

Trees.

Shrubs.

Ground cover:

Mulch.

Pedestrian activity areas. For commercial centers, multiple family residential development projects or mixed use residential and commercial uses, an enhanced landscape design is required for priority pedestrian activity areas. Such features may include the planting of a specimen tree, a decorative rock and boulders feature, a water feature such as a pond or water fountain, or public artwork. Priority pedestrian areas are the pedestrian entrances, including sidewalks, to the project development from the public right-of-way and parking lots.
