Section 660. Four Corners Overlay District.
This section is included in your selections.

A. Purpose and Intent. The purpose for the overlay is to formalize and define development standards to aid in the development and planning of projects within the historic section of the City known as the Four Corners. The goal is to create a pedestrian friendly environment and tie the Four Corners at the intersection of 24th Street and Broadway Road together through unique design elements. It is intended to provide the Four Corners with new and distinct neighborhood commercial developments that will define and unify the community and enhance the gateway to the South Mountain Village and the redevelopment areas of Target Area B and South Phoenix Village.

D. Height, Yard and Area Requirements. All height, yard and area requirements of the C-2 District will apply unless otherwise modified by the following standards.

1. Buildings over 50,000 square feet are subject to a use permit.

2. A build-to line a minimum of 22 feet to a maximum of 24 feet is required along all arterial streets. The build-to line is the width of the public space between the front facade of the building and the street curb line. The buildings may be setback 15 to 20 feet from the build-to line to provide courtyards, plazas and open spaces. (See Figure 1)

Exceptions: An exception will be made for the southwest corner of the intersection of 24th Street and Broadway Road.

3. The minimum linear street frontage build-out is 70% on individual interior lots and 50% on corner lots.

4. Covered walkways, arcades, awnings, cafe eating areas (with three foot high fences) and decorative monument towers may encroach up to 10 feet into the front setback. (See Figure 2)

5. Balconies, bay windows (including display windows), entries and porticos may encroach up to six feet into the front setback. (See Figure 2)

6. Covered walkways and arcades may be no higher than 15 feet above the sidewalk. (See Figure 3)

7. Ten feet of unobstructed sidewalk and an additional eight feet of sidewalk or landscaping are required for pedestrian corridors along arterial street frontages. If a covered sidewalk is provided, there shall be a ten foot wide dedicated sidewalk. There shall be a six-foot landscape strip adjacent to streets.

E. Parking Requirements. The amount of parking is reduced from what is otherwise required in order to encourage more pedestrian activity and less vehicle trips between uses.

Off-street automobile parking space or area shall be provided according to the following table.



Day care center (adult and child care)

1 space per 500 square feet of floor area

Office (< 50,000 square feet)

1 space per 350 square feet of floor area


1 space per 100 square feet exclusive of kitchen, rest rooms, storage, etc.

Retail and commercial

1 space per 400 square feet of floor area

Schools, beauty and vocational

1 space per 100 square feet of classroom area

And 1 space per 400 square feet of administration

Parking for all other uses will not be allowed to exceed the minimum requirement by more than 10%.

F. Design Guidelines and Standards. The design guidelines and standards contained in this section reflect the desired goals and policies for development in the Four Corners Overlay. The City’s general design review policies of Section 507 Tab A of the Zoning Ordinance shall apply to development in the Four Corners Overlay District to the extent they do not conflict with the following standards.

These guidelines and standards consist of Requirements (R) and Presumptions (P) as set forth in Section 507.

1. Parking.

a. Parking areas should be located to the side or rear of the building(s) and should be screened by a three-foot permanent element. The side and rear yard requirement does not apply to parking for buildings greater than 50,000 square feet in area. Access to arterial streets is prohibited where access is available from adjacent side streets or adjacent lots. (P)

Rationale: The location of the parking to the side or rear of the building will provide a more urban streetscape and be more pedestrian friendly.

b. Seventy-five percent of the required parking shall be located behind the building. This requirement does not apply to parking for buildings greater than 50,000 square feet in area. (R)

Rationale: The location of a majority of the parking to the rear of the building will provide a more urban streetscape and be more pedestrian friendly.

c. Lots should have cross access easements to encourage internal continuous vehicular access. (P)

Rationale: Internal site access to various businesses will reduce the number of vehicular trips required and the number of curb cuts.

d. Surface parking lots should not be permitted within 150' of the intersection of 24th Street and Broadway Road with the exception of the parcel on the SWC. (P)

Rationale: Surface parking lots do not enhance the urban streetscape.

e. The perimeter landscaping for parking lots shall be a minimum of 5' in width. (P)

Rationale: Landscaping will help soften the appearance of the parking area.

f. Fifteen percent of the surface parking lot, exclusive of perimeter landscaping and setbacks, shall be landscaped. (R)

Rationale: Landscaping throughout the parking area will soften the appearance of the parking lot.

g. Landscaped islands within parking lots should be a minimum of eight feet wide (inside dimension). (P)

Rationale: The eight-foot width will allow for larger trees which may provide greater shade.

h. Pedestrian amenities such as benches and shaded walkways shall be provided within all parking areas over 100 spaces. (R)

Rationale: Pedestrian amenities will provide a better transition between the parking area and other areas.

i. Trees shall be planted in the parking lot to provide shade for 25% of the parking spaces and/or 50% of the parking lot area at maturity. (R)

Rationale: One of the goals in the environmental planning element of the general plan is to address the urban heat island effect. Parking lots absorb heat during the day and radiate that heat into the atmosphere during the night raising the ambient night-time temperature. Shading the parking lot reduces the amount of heat absorbed during the day.

2. Open space.

a. A minimum of 15% of the lot area shall be developed as either usable hardscape and/or landscaped open space adjacent to the building. The open space shall include areas such as courtyards, eating or dining areas, pathways, parks, plazas, or squares. (R)

Rationale: Open space which includes courtyards, eating or dining areas, pathways, parks, plazas or squares provides an opportunity for people to interact and develops a sense of community.

b. If courtyards are provided, each shall be a minimum of 400 square feet with approximate equal dimensions and surrounded by building for a minimum of 50% of the perimeter. The height of the building should step down to 24 feet. (P)

Rationale: Courtyards must be large enough to be useful and partially surrounded by buildings to be considered a courtyard.

c. If courtyards are provided they should be located at the corners of buildings, between structures and as an entry to major buildings of 50,000 square feet or greater. (P)

Rationale: Courtyards provide an opportunity for people to gather, and the walls of the buildings provide shade.

d. Pedestrian passages between buildings should be a minimum of 15 feet wide and shall link the front of the storefront facade to the rear parking area(s). They shall be covered with either a structural covering or landscape tree canopy. (P)

Rationale: Pedestrians should be able to travel freely from the front to the rear of the lot and be protected from the weather.

3. Buildings.

a. Storefront buildings should have their main entrance opening to a street and/or courtyard. The courtyard may be located on the side of the building but must be clearly visible and easily accessible from the street. (P)

Rationale: The pedestrian should be able to enter the building without passing through a parking area.

b. Storefront buildings should have a minimum of 50% of the area of the first floor street facade as window area. (P)

Rationale: It is important that street facades not be blank walls and provide visual access for pedestrians and motorists.

G. Signs. Signage should be at a pedestrian scale and should improve the image of the streetscape.

1. Site or complex identification signs.

a. Ground signs shall not exceed 40 square feet in area and shall be limited to two sides. The maximum height permitted is six feet, including the base. (See Figure 4) (R)

b. Ground signs shall have a permanent monument type base of concrete or masonry construction and shall have a landscaped area equal to a minimum of four square feet for each square foot of signage. (R)

c. Signs shall identify the name of the business or complex and not include any advertised copy or promotional events. (R)

d. One sign is permitted for buildings less than 50,000 square feet in area. Two signs are permitted for buildings exceeding 50,000 square feet in area. Where two signs are permitted, they shall be placed on opposing streets if the complex is located on a corner lot. (R)

e. Signs may be lit externally by concealed lighting or decorative lighting which matches the exterior theme of the building and complex. (P)

f. One wall, mansard fascia or parapet sign may contain an internally illuminated reader panel with a maximum area of 65 square feet. (R)

g. Theater signs shall be below the roof line and/or parapet. The reader panel shall be used exclusively for the purpose of identifying motion pictures, theater or entertainment which occur on the premises and shall not be counted as a multiple tenant sign. (R)

h. The following table shall apply to single tenant buildings. (R)




Less than 20,000 square feet


24 inches

20,000 to 50,000 square feet


36 inches

greater than 50,000 square feet


48 inches
