(Ord. No. 3063, § 3, 11-18-99)

(1) Purpose: These standards shall function to guide development toward the highest attainable environmental quality at a time in which development and expansion are taking place at a rapid rate; as such development once established provides the living and working environment for hundreds of thousands of families over numerous decades and generations.

(2) Applicability:

(a) It is not the intent of the Council that these guidelines be strictly applied to existing developments on Arizona Avenue, downtown, and any other developed areas.

(b) These standards shall apply to all development except two-family dwellings which occur on an individual isolated basis and are not part of some large project; and single-family dwellings.

(c) In order to accommodate, encourage or promote unusual, unique or experimental methods of development or environmental design, the approving authority (Council, Commission or staff) may depart from standards prescribed herein after having made a finding in writing that such deviation, on balance, will result in environmental quality superior to that otherwise attainable without such deviation.

(3) Relative to streets:

(a) All street and alley rights-of-way shall be dedicated in accordance with current City standards.

(b) Driveways onto major arterials must be consistent with City policy allowing breaks in street medians at one-quarter (¼) and one-half (½) mile intervals. All driveways shall be situated at least thirty (30) feet from an intersection and at least ten (10) feet from an interior lot line.

(4) Site organization:

(a) Setbacks:

1. For parking lots:

a. In proximity to street intersections. See below 2.a.

b. Along arterial streets, parking lots shall be set back at least twenty (20) feet from right-of-way lines.

c. Along nonarterial streets, parking lots shall be set back at least twenty (20) feet from right-of-way lines.

d. Along all other rights-of-way and property lines, unless said property lines are of a smaller parcel (pad) within a larger planned development, all parking spaces and access drives shall be set back at least ten (10) feet.

2. For structures or any physical improvement in proximity to street intersections:

a. Intersections as described below are of value to the entire community. Land situated at the corner of such street intersections shall be landscaped, and remain open and free of buildings, parking areas, driveways, and walls in excess of two (2) feet six (6) inches in height. Ingress and egress drives perpendicular to the street are expected. The dimensions of these open areas shall satisfy at a minimum, the following standards:

b. No vehicle or other obstruction exceeding two (2) feet in height shall be parked at an intersection of two (2) right-of-way lines within triangular area formed by the right-of-way lines and the line connecting them between points located thirty (30) feet from the intersection of said lines.

In order to accommodate, encourage, or promote infill development or redevelopment for properties located within the infill incentive district, the Zoning Administrator may depart from landscape setbacks prescribed herein after having made a finding in writing that such deviation, on balance, will result in environmental and design quality superior to that otherwise attainable without such deviation.

(b) Retention basins:

1. Retention basins may be located in the front yard of parking lots and buildings when they:

a. Do not occupy more than one-half (½) of the landscaped area, when designed to maximum allowable engineering specifications.

b. Are shaped to a pleasing and natural configuration and landscaped in a manner consistent with its location and immediate area.

(c) Walkways: Safe, convenient and pleasant pedestrian circulation shall be facilitated and provided for with walkways, special pavings, bridges, shade, rest area, and other features appropriate to any one (1) specific development.

(d) Bikeways: Provision shall be made for safe, meandering, convenient and pleasant bikeways, minimum eight-foot-wide concrete surface or equivalent, and bicycle storage as appropriate to any specific development.

(e) Screen walls: Screen walls shall be decorative and reflect color, material and/or design of the structure to which it prevails.

(5) Building design:

(a) Quality: Architectural style is not prescribed; the design, however, shall convey a high degree of quality commensurate with the neighborhood and as prescribed in the Chandler General Plan. A standard building design for some other location, climate, environment or set of circumstances may not necessarily fit in a given location in Chandler and shall be modified to be harmonious with the immediate environment and meet the intent set forth in this paragraph.

(b) Building mass: Large building facades are deemed inconsistent with the low-key small-town character of Chandler and are discouraged.

(c) Mechanical equipment screening: All mechanical equipment and appurtenances shall be concealed and/or screened from view in their entirety as an integral part of the building in one (1) of the following manners, and subject to approval by the Zoning Administrator:

1. Parapets are acceptable for screening, provided the height shall be equal to, or higher than, the highest point on the mechanical equipment; or

2. Screening of mechanical equipment shall be constructed of similar materials and painted colors similar to the building, and so arranged that the screening is perceived to be an integral part of the building mass.

All mechanical equipment and appurtenances shall be indicated and shown on building sections and elevations indicating dimensions of equipment and screening.

The Zoning Administrator may reduce or waive screening requirements for roof-mounted equipment if:

i. The building is a mid-rise development and roof-mounted equipment will not be visible from any adjacent property as seen from a point six (6) feet above ground level at the property line or sidewalk on the opposite side of the street; or

ii. The building is located within an industrial center or business park and roof-mounted equipment will not be visible from any arterial street or residential property.

All mechanical equipment shall be screened from view in their entirety as an integral part of the building as required in section (5)(c) when the subject building is abutting a residential zoned property regardless of location or building height.

(d) Metal buildings:

1. Metal buildings will not be allowed on roads designated by the General Plan as arterial roads except that:

a. A portion of a building may be constructed using an exterior metal finish where said portion is determined to enhance the design quality of the building architecture and is not the primary building material.

b. Shipping containers may be used as a building material if the building is designed with additional materials and fenestration to enhance the quality of the architecture that together provide a creative and innovative architectural design. The character, scale, and massing of said design shall be compatible with the buildings of the surrounding area.

2. Metal buildings may be allowed within industrial parks and at other locations not visible from an arterial street upon the Planning and Zoning Commission finding that the facade of the building is architecturally treated so as to assure mitigation of the starkness of metal construction and environmental compatibility with the surroundings.

(6) Miscellaneous:

(a) Any commercial or industrial development using outside storage area for equipment, vehicles or materials shall screen such area from view with a six-foot masonry or concrete wall excluding approved gated openings.

(b) All trash and/or refuse collection areas shall be enclosed by a six-foot masonry or concrete wall, excluding approved openings. The location of such area shall be approved by the Department of Public Works.

(c) Dismantling, servicing, repairing, etc., of vehicles and/or equipment shall be within completely enclosed buildings or within an area enclosed by a concrete, masonry, or similar material solid wall except openings for ingress and egress which shall be furnished with solid gates.

All development of recreation/open space areas in accordance with these standards shall meet approval of details by the Planning and Development Director.

(d) Interface with single-family areas: Where abutting single-family residential developments, the projects shall be so designed as to minimize impact upon the privacy of the single-family residential area. This may include considerations such as limiting building height to one (1) story, windows orientation, decorative walls, and the use of trees.

(e) Specific design attention areas: The design of all courtyards and pedestrian areas shall relate to "human scale." Large unvaried building facades shall be avoided. Common open spaces, rather than parking lots, shall be used as central features. Lighting shall be provided for both convenience and security. Living units and windows shall be arranged to provide privacy. Parking shall be in a location that is convenient to the occupants of the units.

(f) Convenience goods and personal services: In order to minimize the need for travel, when feasible, projects of three hundred (300) units or more shall provide such facilities to the residents within the project. In cases where convenience goods and personal services are located in areas in the vicinity or adjacent to the multi-family projects, safe, convenient and attractive pedestrian access shall be provided to such facilities.

(g) Energy conservation: The development shall incorporate those energy conservation measures that can only be provided at the time of land development or initial construction, such as:

1. Shading of south and west sides of building by overhangs and/or trees.

2. Provision of shade trees on the south and west side of streets.

3. Alternate sources of energy, such as solar heating offered as standard equipment, or at least as an option.

(h) Condominiums: There are additional requirements for condominiums because the dwelling units in such developments are individually owned. There shall be: additional soundproofing between dwelling units; adequate indoor and outdoor storage; dwelling units shall have distinctive entryways to avoid the monotony frequently found where a row of doors line a corridor. The number of units in a project shall be sufficient, as so demonstrated, to support the provision of management and maintenance services.

(i) Landscaping: The amount of landscaping shall be of sufficient intensity to create a pleasant and comfortable living environment with the amount of plant material dependent on the size of the vegetation as well as the shape and size of areas to be landscaped.

(j) Security: All of the open spaces shall be observable to minimize the opportunity for unruly conduct and to create the feeling of "ownership" by the occupants of the projects.

(k) Elderly care housing-occupancy: A deed restriction shall be recorded limiting use to elderly care housing. Change or conversion to other uses or family residential is subject to Council approval to remove said deed restriction by meeting all requirements for such use.

(8) Additional requirements for shopping centers, office and commercial complexes:

(a) Adjacent to residential development: When such projects are next to or across an alley from a rear or side yard of single-family residential development:

1. Commercial buildings shall be no closer than twenty-five (25) feet, plus one (1) additional foot for each foot of height of the commercial building, from the residential property line.

2. Second-story window balconies and other openings are allowed only when demonstrated to and approved by the Zoning Administrator that back yards of adjacent residences will not be visible from such balconies or openings by persons sitting or standing in the commercial buildings.

3. Building elevations facing and visible from the adjoining residences and back yards shall be designed to be in harmony with the residential environment through the use of color, material, texture and varied treatment of segments of the commercial building.

(b) Pedestrian circulation:

1. It is deemed appropriate that walkways required in section 35-1902(4) be provided in all shopping centers, offices and other commercial complexes. Such walkways shall be A.D.A. (Americans with Disability Act) accessible and designed and provided to serve internal pedestrian circulation needs, and be integrated with pedestrian access to and from surrounding land uses, sidewalks and walkways.

2. Bus bay locations, where applicable, shall be integrated with pedestrian walkways that provide direct access to the adjacent commercial center.

3. All perimeter sidewalks shall be at least partially meandering and removed and separated from the curb by landscaping barrier or other decorative material. These sidewalks shall be not less than six (6) feet in width except that, in locations anticipated heavier than normal pedestrian traffic, the Zoning Administrator may require these to be eight (8) feet in width.

4. There shall be at least one (1) other special feature that is pedestrian oriented for each fifty thousand (50,000) square feet of gross floor area such as but not limited to fountains, sculpture, mural, or other generally accepted forms of art.

(c) Independent building pad sites: For the purpose of this section, commercial pad sites are uses that stand apart from, and hence not perceivable as, part of the main building complex. pad sites may be developed as single freestanding uses, such as a restaurant or bank, or a cluster of uses sharing common architectural detail and materials, open spaces, and shaded areas and pedestrian connections. The number of pad sites permissible in a shopping center shall be limited to one (1) per arterial street frontage, with corner pad sites to count as one (1) of the frontage allowances. Multi-user pad sites are permitted only when the uses are integrated and clustered within a common open space with seating areas and pedestrian walks, share common architectural details and materials (i.e., color, texture) portrayed by the main complex, and not separated by vehicular movement. The number of uses on one (1) pad site shall not exceed two (2) although more may be approved through the preliminary development plan (PDP) process when environmentally commensurate with the size and scale of the shopping center.

Notwithstanding the foregoing, the Zoning Administrator may approve more than two (2) free-standing pad sites per development administratively, upon determining that all of the following apply:

A. The pad will enhance the quality of the overall development or revitalize an existing commercial center;

B. An additional pad will make use of an area that is currently underutilized;

C. There is sufficient area on the site to accommodate safe and adequate on-site traffic circulation and the site has been designed to prevent drive-through queuing from backing onto main driveways or public streets;

D. No more than one high-turnover user per street frontage;

E. The pad(s) and the overall commercial center in which it is located comply with Article XVIII parking and loading regulations;

F. The architectural design (i.e. building form and materials) of the pad is compatible with and superior to existing buildings in the same center through the following but not limited to;

i. Increased levels of architectural quality

ii. Greater material diversity

iii. Enhanced usable space and/or pedestrian connection

iv. Activation of street frontage

v. Higher levels of landscape design

vi. Creative design solutions for back-of-house functions

1. Circulation: One (1) drive-up or drive through window per pad site is permissible as long as the drive-up does not conflict with parking maneuvering areas, main-stream vehicular movement, or in itself create an unsafe traffic situation. Drive through lane entry and exit shall be separated from vehicular parking areas, through curbing, landscaping, etc. Textured paving treatments shall be provided at all crosswalks, driveway entrances, and on-site pedestrian crosswalks. All drive-up facilities, including drive-up lanes and queuing areas shall be adequately screened from street view by building orientation, or by a landscaped berm and retaining wall measuring four (4) feet from grade of the driving lane, and situated so as not to disrupt safe traffic flow. All queuing lanes for fast food and similar high turnover uses shall be a minimum of fourteen (14) feet in width. Establishments with multiple queuing lanes that offer on-site ordering shall have at least one (1) queuing lane with a minimum of one hundred fifty (150) feet in length measured from the drive-up window to the start of the lane. Queuing on said lane shall be provided to accommodate a minimum of one hundred twenty (120) feet from the start of the lane to the menu board. Any additional queuing lanes shall not be counted towards the minimum queuing requirement provided herein. Queuing lanes dedicated solely for picking up pre-ordered items and which do not have a menu board shall provide a minimum of sixty (60) feet in length measured from the pick-up window to start of the lane. This queuing length standard is not intended for such uses as drug stores, banks, dry cleaners, etc.

2. General design: All PAD sites, though isolated from the main complex, shall be designed to provide a landscape and architectural setting to the larger complex. Any PAD site building(s) twelve thousand (12,000) square feet or greater in building area, located within any commercial site that is ten (10) acres or greater in size, shall be allowed to be constructed prior to the balance of the commercial center. Any PAD site buildings twenty-five thousand (25,000) square feet or less in building area, located within any commercial site that is less than ten (10) acres in size, shall be constructed concurrently or subsequently with at least twelve thousand (12,000) square feet of additional building area in the commercial center.

Freestanding building adjacent to the main complex structures will not be considered PAD sites if the freestanding building is not separated from the larger complex by vehicular movement, improved vehicular surfaces, or retention area.

PAD site buildings shall portray detailed exteriors on all sides to avoid blank or monotonous faces: wall perimeters shall be landscaped. In no case shall parking areas or other improved surfaces for vehicles extend to building walls. PAD sites shall not exceed one (1) story in height.

3. Any high turn-over uses (fast food, convenience stores, service stations, etc.) must be integrated within larger planned commercial and office centers. However, on-sites where the contiguous area is generally insufficient to allow a larger planned center, relief may be considered through the provisions of the Planned Area Development (PAD) process, subject to approval by City Council.

(d) Deceleration lanes: Each perimeter curb cut shall have a deceleration lane in length approved by the City Engineer. The City Engineer may waive this requirement upon making the finding that such lanes are not feasible or necessary.

(e) Architectural standards: The intent of the following standards is to encourage creative and innovative design techniques, quality and merit.

1. Building features that are used for advertising or national image (corporate stylized architecture), shall be prohibited.

2. Building architecture shall promote consistent architectural character and detail on all sides of the structure, including the use of building materials, and not merely limited to color changes only.

3. Where applicable, building mass shall be broken by dividing into smaller components and creating functional open space and pedestrian oriented areas between buildings.

4. Any one (1) building material shall be limited to a maximum of sixty-five (65) percent of the total area of each building facade, unless dictated by an architectural style that prescribes a particular building material as the dominant feature (e.g., Pueblo, Santa Fe style, etc.).

5. Flat walls on buildings shall be minimized by incorporating such techniques as pop-outs or pilasters or recessed features or other vertical relief elements at a minimum interval of every twenty-four (24) feet.

6. Rooflines shall be varied in height, form, and materials. Parapet rooflines shall be varied by stepping up and down or incorporating pitched roof elements.

7. Covered canopies shall be provided at tenant entries.

8. At least one (1) common pedestrian seating area shall be provided in a landscape setting on-site for every seventy-five thousand (75,000) square feet of building area. Developments that have less than seventy-five thousand (75,000) square feet of building area shall provide at least one (1) common pedestrian seating area.

9. Drive-through menu boards shall be screened from street view, and architecturally integrated with building design through the use of common materials and colors.

10. Design of gas canopies shall be integrated with adjacent building architecture through the use of similar materials, colors and roof forms.

11. Gas canopy lights shall be flush with the bottom of canopy. Gas canopy bottom edge shall be a maximum of fourteen (14) feet six (6) inches above finish grade, unless canopy is integrated into convenience store building.

12. All gas tank vent piping shall be screened from arterial streets and public view.

13. Screening shall be architecturally integrated for the service entrance section (SES) and all utilities. All ground-mounted equipment shall be screened from public view by a concrete or masonry wall or landscaping, equal to or greater in height than the height of the mechanical equipment.

14. All transformer boxes, meter panels and electric equipment, back-flow devices and any other utility equipment, not able to be screened by landscaping or walls, shall be painted to match the building color.

15. Any roof access ladders shall be located inside the building. Roof drainage shall utilize interior roof drains or be architecturally integrated into the building design. Architecturally integrated roof drains shall require additional articulation beyond paint accents.

16. Provide public artwork including but not limited to sculptures and murals.

(f) Project design guidelines and specifications: Project design guidelines and specifications shall be developed by the applicant, submitted with the earliest zoning application, and approved by the approving authorities (Council, Planning Commission, and Staff), but no later than the site development plan submittal preceding the issuance of the building permit. These guidelines and specifications shall describe how the site development plan design standards in section 35-1902 shall be met in any particular project. Once approved by the approving authority, these guidelines and specifications shall become binding on all development and construction within this project. The Zoning Administrator may accept minor departures from such approved guidelines and specifications when such request is made in writing and upon finding that:

1. The departure is minor and does not change basic intent or quality; or

2. An alternate which on balance is greater in quality than previously approved.

Any other changes shall be approved only by the approving authority. The above design criteria specifications shall include consideration of adjoining existing or approved projects to avoid clashing and to promote identity. This shall be observed also by all developers at the intersections of arterial streets.

It is not the intent of this provision to promote or attain similarity or sameness. The intent of this provision is to attain identity for a project and to attain identity at intersections at arterial streets so that such intersections could become unique and readily perceivable nodes in Chandler. The developer's responsibility and creativity are relied upon in fulfilling these purposes.

(g) Additional quality standards: The intent of the following standards is to encourage creative and innovative design techniques, quality and merit. A minimum of six (6) of the following items shall be achieved for shopping centers, office and commercial centers.

1. Provide direct collector street access to commercial center.

2. Locate at least fifty (50) percent of freestanding PAD sites within a landscape setting along an arterial streetscape.

3. Provide angled building orientation to achieve varied alignment of building fronts and site design features, that in turn creates functional outdoor spaces, and/or enhanced intersection feature.

4. Provide tree lined "boulevard" at median break(s), with detached sidewalks and landscaping that lead directly into a pedestrian plaza or other amenity.

5. Stagger parking setback by at least ten (10) feet or vary orientation of parking lot along arterial streetscape, while maintaining a minimum twenty-foot setback from the right-of-way.

6. Incorporate unique planter and seating features, recurring in pedestrian areas throughout site, including areas along the front of buildings.

7. Develop an overall character theme that incorporates unique amenities (i.e., signage, light fixtures, screen walls/seat walls, etc.).

8. Provide pedestrian features in common landscape areas in addition to the required special features, such as seat wall planters, or other pedestrian oriented features.

9. Provide at least two (2) unique freestanding architectural site features that reflect the building architecture in addition to the required special features, such as entry arches, trellises, clock towers, rail fencing, etc.

10. Develop unique water features in a pedestrian setting internal to the site development, in addition to the required special features.

11. Any other design amenity, which is otherwise not required but which meets the general intent for design innovation, may be substituted for any of the above additional quality standards.

(9) Additional requirements for new non-residential water users of nine thousand (9,000) gallons or more per day.

(a) New non-residential water users who have an estimated annual use which averages nine thousand (9,000) gallons per day or more (excluding turf related facilities) are required to submit a "water use plan" sealed by an Arizona registered architect or engineer that it complies with this section as a condition of issuance of a building permit. The "water use plan" shall contain at least the following:

1. A description of any available water conservation training programs offered to employees;

2. Whether alternative water sources will be used (i.e., effluent, poor quality groundwater or other non-groundwater sources);

3. Operating levels of total dissolved solids (TDS) or conductivity for cooling towers and total cooling capacity;

4. Whether the user will use the best available conservation technologies in accordance with existing process uses (i.e., re-circulating systems for process water, alternative dust control methods, automatic shut-down devices to eliminate continual running water);

5. Any plans for the reuse of wastewater or process water at the facility; and

6. Type of landscaping and irrigation system.

(b) Such water use plan shall be submitted together with the information required to be submitted with the site development plan.

(10) Locational criteria and site development standards for large single use retail development:

(a) Locational criteria: Large single use retail, as defined in section 35-200 of this Code, shall only be permitted on property zoned as Planned Area Development (PAD) for such use, in accordance with the requirements and provisions of Chapter 35, Article XVII of this Code, and further subject to all of the following location criteria. Any proposal to expand an existing retail use, which subsequently brings the total building coverage of that use to one hundred fifty thousand (150,000) square feet or more, shall also require conformance with all of the following standards, for the entire site development. Council may approve departure from these standards upon finding that such departure is warranted, based upon consideration of mitigating circumstances, design innovation, or other meritorious feature(s), as provided for in Chapter 35, Article XVII of this Code.

1. Any parcel proposed for a large single use retail development shall be adjacent to a freeway interchange, or shall front along two (2) major arterials forming an intersection designated by the Chandler General Plan as "commercial node," or as "regional major commercial development," or other successor designation specified in the general plan, or in an area plan approved by the Mayor and City Council, that expressly provides for such large single use retail development.

2. A minimum distance of one thousand five hundred (1,500) feet, as measured on a straight line, shall be required from the nearest property line of any parcel currently zoned for low density single-family residential use, to the nearest exterior wall of the large single use retail building.

a. For purposes of this measurement, the phrase "low density single-family residential use" shall mean a subdivision of land, as defined in section 35-200 of this Code, located within the City jurisdiction, with a net overall density in the range of zero (0) to four and one-half (4.5) dwelling units/acre. For purposes of this measurement, neither the AG-1 (Agriculture) nor the MH-1 (Mobile Home) zoning district shall be considered as a low density single-family zoning designation.

b. The one thousand five hundred (1,500) foot distance may be reduced or waived altogether by Council if based upon a finding that other mitigating circumstances already exist on, or adjacent to, the site proposed for large single use retail development. Such mitigating circumstances may involve existing non-single-family land uses or zoning designations, or other physical barriers such as a major arterial right-of-way, freeway right-of-way, railroad or canal right-of-way, which Council may find achieves an effective separation and buffer from the land use impacts of the large single use retail development.

c. The one thousand five hundred (1,500) foot distance may be reduced, or waived altogether, by Council if based upon a finding that the large single use retail development proposal demonstrates a combination of superior architectural or site design techniques, such as, without limitation, i) attaching other accessory retail shop space and storefronts to displace at least a portion of what would otherwise be a lengthy exterior front wall plane of the large single use retail building; ii) extensive greenbelts not less than one hundred (100) foot in width that feature mature landscaping, architectural theme walls, and terraces that cause the finished grade of the large single use retail building to be at least six (6) feet lower than the finished lot grade of the nearest low density single-family residential use; iii) relocation of loading docks and overhead bay doors to another side of the building which does not face any adjacent residential use, and which in turn causes elimination of any rear service drive or other means of access to the rear of the building other than pedestrian doors; iv) completely separating the large single use retail building with smaller scale buildings accommodating less intensive land use(s), which provides an effective transition to any adjoining residential use.

The requirements of this subsection 35-1902(10)(a)2. shall not apply if the developer of such low density single-family residential use, was required by condition of zoning as approved by the Chandler City Council, to give full and adequate disclosure that said residential subdivision was within one thousand five hundred (1,500) feet to another site currently designated for regional commercial use, as shown on the Chandler General Plan, wherein such designation may permit large single use retail development.

3. An application requesting zoning approval for a large single use retail component, may also request zoning for a single-family use as a component of a mixed use project only when each of the following conditions are met:

a. The large single use retail parcel shall be expressly identified for such use as part of a mixed use Planned Area Development (PAD) zoning application, wherein such application as approved by City Council, also depicts the single-family residential parcel(s), and any transitional land use parcels and buffers adjoining the large single use retail parcel.

b. Full and adequate disclosure of such large single use retail location shall be given by the developer or homebuilder of the single-family residential use within fifteen hundred (1,500) feet, to any prospective homebuyer in the manner specified as a condition of City Council approval, for the Planned Area Development (PAD) zoning application.

c. Preliminary development plan approval for the large single use retail parcel, in the manner set forth in section 35-1706 of this Code, shall be required either prior to, or concurrent with, preliminary development plan approval for one (1) or more single-family residential parcels within said mixed use development proposal.

d. The required Planned Area Development (PAD) zoning application, wherein such mixed uses are identified, shall also demonstrate sufficient buffer separations using such elements as street right-of-way, stormwater retention area(s), landscaping techniques, and masonry walls, in combination to achieve complete separation. In no event shall any parcel proposed for large single use retail, share a property line with any parcel proposed for low density single-family use.

4. Any parcel proposed for large single use retail development shall be a minimum distance of one thousand three hundred (1,300) feet from any site currently zoned, or built, as a public or private elementary school, middle school, junior high, or high school.

a. In no event shall any development site containing a large single use retail parcel, gain vehicular access from a local street, collector street, or private drive, that also provides vehicular access or frontage to a public or private elementary school, middle school, junior high, or high school.

b. The minimum distances required by this subsection 35-1902(10)(a)4., between the large single use retail building and any given school, shall be the shortest straight line measurement from the school property line to the nearest exterior wall of the large single use retail building.

The requirements of this subsection 35-1902(10)(a)4. shall not apply to any elementary school, middle school, junior high, or high school located on property zoned for uses other than low density single-family residential use.

Notwithstanding conformance with all of the above locational criteria, City Council may deny an application for the Planned Area Development (PAD) zoning designation, in accordance with the provisions set forth in section 35-1706(4) of this Code.

(b) Site development standards: In addition to the site development and landscaping standards set forth in sections 35-1902 and 35-1903 of this Code, large single use retail shall also be subject to conformance with the following additional standards. Council may approve departure from these standards upon finding that such departure is warranted, based upon design innovation or other meritorious feature(s) as provided for in Chapter 35, Article XVII of this Code:

1. Maximum total site coverage of all buildings, shall not exceed twenty-four (24) percent of the net site area.

2. Minimum front, side, and rear setbacks for all large single use retail building(s) and parking, as otherwise specified in section 35-1902 of this Code, shall be increased at the rate of two (2) additional feet for each ten thousand (10,000) square feet of building coverage over one hundred fifty thousand (150,000) square feet. Such setbacks from any public street shall be measured from the future right-of-way line, wherein such right-of-way width is determined in accordance with the Circulation Element of the Chandler General Plan.

3. The architecture of the large single use retail building, together with any pad building(s) or in-line shops, shall demonstrate visual interest on all exterior sides through the use of such techniques, without limitation, as wall plane changes, color and material changes, pop-outs, reveal lines, scoring, varied roof lines and slopes, recessed features, articulated customer entrances, canopies, colonnades, and other elements, all of which effectively integrate the building mass with its surroundings, and bring proportion to its horizontal and vertical dimensions.

4. Entry drives shall be aligned with any point of access to an arterial street that provides full turning movements, as approved by the City Transportation Engineer. Said entry drive(s) shall be defined as a boulevard, thereby separating entry/exiting movements from parking space search maneuvers.

5. Sidewalks not less than six (6) feet in width shall be provided within the site development, providing direct pedestrian access from the arterial sidewalks to primary customer entry doors. Such on-site sidewalks shall be separate and distinct by use of landscaping, color, and material changes. In addition, a minimum ten (10) foot wide sidewalk shall be provided parallel to the front elevation of the large single use retail building for its entire length, and separate from any parking space overhang, driving aisle or landscaping as required in section 35-1903 of this Code.

6. Any outdoor display areas for merchandise shall be enclosed by fence walls integrated with the architecture, color, and materials of the primary building, and may include wrought iron for visibility. Such fence wall enclosures shall be a minimum four (4) feet or greater in height.

7. Any areas used for shopping cart containment as may be provided adjacent to the building, shall be fully enclosed and screened by a minimum four (4) foot high masonry wall, with berming and landscaping in the quantities set forth in section 35-1903 of this Code.

8. Outdoor storage of merchandise or other miscellaneous material, including containment in metal bins, shall not displace any portion of the site development intended for parking, access, landscaping, or loading, and shall be screened in the manner specified in section 35-1902(6)(a) of this Code.

9. A traffic study shall be submitted for approval by the City Transportation Engineer, in conjunction with the preliminary development plan submittal requirements set forth in section 35-1706 of this Code. Recommended measures and improvements to mitigate traffic impacts shall be the responsibility of the project developer.

10. A photometric plan shall be submitted for approval by the Zoning Administrator, in conjunction with the preliminary development plan requirements set forth in section 35-1706 of this Code. Said plan shall demonstrate an illumination level in the range of one and one-half (1.5) to two (2.0) foot-candles, for approval by the Chief of Police or designee. Such submittal shall include catalogue cuts of all lighting fixtures with shields to insure down lighting only, concealed point sources of light, and prevent overspill onto adjoining properties.

11. Overnight parking of recreational vehicles anywhere within the site development shall be prohibited.

(1) Purpose: The purpose of this section is to provide minimum landscape development standards which will promote the general welfare of Chandler residents through the provision of an outdoor environment which will:

(a) Create aesthetically pleasing views and vistas along public streets.

(b) Complement and enhance the functional and aesthetic design of new building and site development projects.

(c) Provide visual screening of parking, service and storage areas.

(d) Mitigate the adverse impacts of higher intensity land uses upon lower intensity uses through the provision of needed "landscape buffers."

(e) Promote water conservation by restricting the use of turf and ornamental water features and requiring the use of low-water-use plant materials.

(f) Promote climate modifications for enhancement of pedestrian environments at street frontages, parking lots and building facades.

(g) Provide maximum shade on ground surfaces to reduce the "urban heat island effect."

(2) Applicability: These landscape standards shall apply to all new developments, excepting single- and two-family dwellings, which require the approval of a site development plan or subdivision plat by the City of Chandler.

(3) Definitions:

(a) Director: The Development and Community Services Director or his/her designated representative.

(b) Landscaping: Shall include all living plants such as trees, shrubs, vines, vegetative ground cover, organic or inorganic materials, earthen berms, walls, walkways, plazas, courtyards, lighting, benches, trash containers, ponds, fountains, sculptures and other site furnishings creating an attractive environment.

(c) Landscape plan: A graphic representation of the development of a site which illustrates the nature, design and location of all landscaping elements and materials.

(d) Interior open space: That open space encompassed by line extensions of the exterior walls of one (1) or more buildings constructed on a common building site.

(e) Reclaimed water: Water which has been processed by a municipal wastewater treatment plant and made available for reuse.

(f) Salvaged/harvested water: Collected stormwater for landscape use.

(4) Landscape design plan: All landscape plans shall be drawn at a minimum scale of one (1) inch equals thirty (30) feet (maximum sheet size thirty-inch by forty-two-inch) and contain the following information:

(a) Building footprints and roof overhangs, walkways, parking surfaces and vehicular overhang lines, property lines, right-of-way lines, easement lines and sight angle clearance lines.

(b) Calculations of the square footage and percent of total site of all site elements, including building footprints, parking, and landscape area. Landscape area shall also be further subdivided into subcategories of turf, shrubs/ground cover, and inorganic materials.

(5) Landscape design guidelines: Landscaping shall be designed, installed and maintained in general accordance with the following guidelines:

(a) Xeriscape principles: Landscape developments shall be designed, installed and maintained in accordance with the following seven (7) basic principles of xeriscape.

1. *Planning and design: Use a water conservation design. Implement a "mini-oasis" concept. Water-using plants and turf should be concentrated in small areas near buildings where they may be enjoyed at the pedestrian level.

2. *Limited turf areas: Limit the use of turf to small areas where it will be actively used and efficiently watered.

3. Efficient irrigation: Utilize the most efficient irrigation system for the area being served. Drip individual plants rather than flood larger areas. Group plantings together with common water requirements to be watered on the same control zone.

4. *Soil improvements: Add soil amendments (improvements) within planted areas to increase the water-holding capacity of the soil and improve the health and vigor of plants.

5. Mulching: Cover final soil surfaces with organic or inorganic mulches to insulate soil temperature extremes and conserve moisture.

6. *Lower-water-demand plants: Utilize only those plants listed on an officially approved low-water-use plant list.

7. Appropriate maintenance: Maintain irrigation systems so they operate at peak efficiency. Lessen water demand by keeping weed growth down and by thinning unwanted wood from trees rather than cropping them.

*Except when reclaimed water is used.

(b) Unity and continuity: Landscape unity and continuity may be significantly enhanced through the selection of a dominant tree and shrub species. Such dominance shall be established by making the selected species clearly in the majority (sixty (60) percent plus).

Note: Plant palettes, except for turf areas in excess of the limitations established by these landscape standards, partially implemented through the construction of one (1) or more phases of a previously approved master planned project shall be continued throughout the development of that project.

(c) Plant massing: The massing of trees and shrubs into groups containing three (3) or more plants is required unless standards elsewhere within these regulations only require a single element, e.g. single trees within parking lot planter islands. Planting of single-shrub specimens, unless used to repeat an element already established within a massed planting within the same visual area, is prohibited. Shrub and ground cover spacing within massed beds shall be spaced in accordance with the spacing standards contained within appendix C [to this section].

(d) Plant associations: The grouping of plant species commonly found together in natural associations or of common environmental requirements (soil type, water, sun exposure, temperature limitations, etc.) is required.

(e) Plant spacing: In order to foster a more natural look, an uneven spacing of plants; unless such plants are being used to create a massed shrub or ground cover bed, is required. Unless dense massing is needed for screening or other specific design purposes, shrub spacing should be sufficient to allow plants to reach their natural mature size and form.

(f) Consistency with adopted streetscape standards: Street frontage landscaping shall be consistent with previously adopted specific streetscape standards (i.e., Ray Road Streetscape Standards).

(6) Standards: All turf areas equal to or greater than five (5) acres in size shall be watered exclusively with reclaimed water when reclaimed water is available in the arterial street. All infrastructure need to accept reclaimed water when it is available in the arterial street shall be installed as a part of the development. When effluent is used, all turf areas equal to or greater than five (5) acres in size shall be overseeded with a winter lawn. All new developments and modifications to existing developments shall be landscaped in accordance with the following minimum standards.

(a) Plant material:

1. Low-water-use plants required: Except when reclaimed water is used, plant material species (trees, shrubs, ground cover, vines, etc.) shall be limited to those which are included within the latest amended edition of the "Low-Water-Using Plant List" approved by the Director of the Phoenix Active Management Area of the Arizona Department of Water Resources (appendix A). Any plant material species may be used if irrigated by a reclaimed water source.

2. Arizona Nursery Association-Tree specifications: All trees shall comply with the latest amended edition of the "Arizona Nursery Association — Recommended Tree Specifications" (appendix D).

3. Minimum planting size: Unless specified elsewhere, all plant material shall be of the following minimum sizes:

*Date palm or fan palm trees in excess of fifteen (15) feet in trunk height may qualify as a required thirty-six-inch box or forty-eight-inch box planting size.

(b) Landscape area requirements: All portions of a development site not utilized for building development, service areas, paved or improved storage areas, parking driveways, etc., shall be landscaped. Minimum areas of landscaping are as follows:

1. Front yard/street right-of-way areas: All front yard areas and street right-of-way areas located between developed on-site improvements and the back of existing or future public sidewalks or street curbs, except needed access driveways, shall be fully landscaped.

All street frontage landscaping located adjacent to driveway exits and street intersections shall be designed, installed and maintained in accordance with the height, location and sight visibility requirements of the City of Chandler Standard Details (detail C-246).

2. Parking lot area: A minimum of ten (10) percent of the interior surface area of all parking lots shall be landscaped. Planter islands, uniformly distributed throughout the interior parking area, a minimum of nine (9) feet in width (measured from outside face of curb to outside face of curb) and protected by raised curbs. Diamond planters shall be installed in commercial and office development and uniformly distributed between planter islands. Such planters shall be a minimum of five (5) feet square in size, oriented in a diagonal fashion, and shall occur at the following minimum frequencies:

Note: Planters, as required above, may not meet the ten (10) percent planting requirement. The deficiency shall be made up by increasing the size of the planter islands and/or increasing the width of perimeter landscape areas created by building and parking setback requirements.

3. Landscape buffers/perimeter landscape strips: A landscape strip a minimum of ten (10) feet in width shall be provided along all site boundary lines.

4. Building structures: Foundation planting shall be provided at walkways adjacent to buildings and planters up to building edge, where appropriate.

Except as provided in Section 35-1903. public or private rights-of-way located in the City of Chandler shall only be planted with plants listed on the low-water-use plant list as approved by the city zoning administrator. Exceptions to the approved plant list through use of various water-conserving techniques shall be subject to review and approval by the Arizona Department of Water Resources, City Engineer, and Planning Director.

It is in the best interests of the City to promote water conservation techniques within rights-of-way, thereby encouraging innovative landscape design through low-water-use plant material. Location of said landscape materials shall conform to standards outlined in the Zoning Code, Section 35-1903, including but not limited to size, ratio of plantings to street frontage, and percentage of coverage. It is not the intent of the water conservation program to promote installation of turf or other high-water-use plant materials located within rights-of-way.
