Town of Sahuarita, AZ Chapter 18.75 OFF-STREET PARKING AND LOADING STANDARDS

§ 18.75.010 Purpose and scope.

A. Purpose. This chapter provides standards for the development of parking and loading facilities, in order to:

1. Ensure sufficient off-street vehicle and bicycle parking facilities by establishing parking requirements for land uses.

2. Reduce excessive off-street parking by encouraging the shared use of vehicular areas and the use of public transit.

3. Promote pedestrian safety by separating vehicular use areas from pedestrian areas.

4. Encourage safe, convenient, and efficient design of parking spaces, circulation, and access areas.

5. Improve air quality by requiring paving of vehicular use areas.

6. Promote enhancement of the community identity and the appearance of town roadways and development areas.

B. Scope. The provisions of this chapter apply to:

1. New development.

2. New uses replacing existing uses. Whenever the use of an existing development is changed to a new use which requires more parking spaces under this chapter than were required for the prior use, additional parking spaces shall be provided in accordance with the requirements of this chapter. No occupancy permit shall be issued until the planning and building director has approved the parking requirement for the new use. Shared parking arrangements will be considered in accordance with STC § 18.75.050(B).

3. Expansions.

a. All projects that propose an expansion of 25 percent or more or a series of expansions cumulatively resulting in a 25 percent or greater expansion in square footage, gross floor area, etc. shall meet the requirements of this chapter for the entire property.

b. If an expansion is less than 25 percent or if a series of expansions cumulatively results in less than a 25 percent expansion in square footage, gross floor area, etc., the requirements of this chapter apply only to the proposed expansion.

§ 18.75.050 Administrative modification of parking requirements.

The planning and building director may grant the following modifications of off-street parking requirements:

A. Calculation of Required Parking Spaces for Mixed-Use Development. The total number of required spaces for a development of two or more different land uses may be reduced to 90 percent of the sum of the cumulative amount required for each separate principal use.

B. Alternative Parking Analysis for Shared Parking or Mixed-Use Development. When a mix of uses creates staggered peak periods of parking demand, shared parking calculations shall be made to reduce the total amount of required parking for residential, retail, office, institutional and employment uses. A parking reduction plan reduces the total spaces required. There is no limit to the number of required spaces that may be reduced, provided the following standards are met:

1. The plan shall be prepared by a traffic engineer or similar transportation professional and approved by the development review committee;

2. The plan includes a traffic generation study and land use profile of the development;

3. The plan shows that the reduced parking will ensure sufficient parking for the proposed uses;

4. The plan does not impede safe passage of moving traffic and does not increase traffic congestion;

5. A covenant runs with the subdivision plat or development plan noting adherence to the range of uses covered by the reduction plan;

6. A future revision to the covenant restricting uses may require submittal of a revised plan or an increase in parking spaces;

7. A combined residential and nonresidential development must be in a single structure or unified development;

8. Pedestrian access is provided to and from the parking area and each building or use;

9. Parking spaces that are reserved for a specific business (e.g., reserved for doctors only) shall not be counted toward meeting the shared parking requirements; and

10. Any other factors that may be unique to the applicant's development proposal.

C. Alternative Parking Analysis for Individual Use. An individual parking reduction plan may reduce the total spaces required. There is no limit to the number of required spaces that may be reduced, provided the following standards are met:

1. The plan shall be prepared by a traffic engineer or similar transportation professional and approved by the planning and building director with a recommendation from the town engineer;

2. The plan includes a traffic generation study and land use profile of the development;

3. The plan shows that the reduced parking will ensure sufficient parking for the proposed uses;

4. The plan does not impede safe passage of moving traffic and does not increase traffic congestion;

5. The covenant runs with the subdivision plat or development plan noting adherence to the range of uses covered by the reduction plan;

6. A future revision to the covenant restricting uses may require submittal of a revised plan or an increase in parking spaces; and

7. Any other factors that may be unique to the applicant's development proposal.

D. Parking in Excess of the Maximum.

1. The planning and building director may approve:

a. Parking lots with more spaces than the allowed maximum, provided all of the spaces above the maximum number are composed of a pervious surface.

b. Parking lots with additional impervious parking spaces up to 10 percent above the allowed maximum spaces where the use of pervious spaces would not be environmentally sound and where a stormwater management plan is included with the application.

c. Parking lots with additional impervious parking spaces up to 20 percent above the allowed maximum spaces, provided:

i. Depressed landscape islands nine feet in width and containing a tree canopy and groundcover shall be provided for each row of six parking spaces.

ii. A stormwater management plan shall be included with the application.

2. At the planning and building director's discretion, a public hearing before the board of adjustment as per STC § 18.93.030 may be required for requests for parking in excess of the maximum.

E. Application. An applicant desiring one of the above modifications may submit a written request with justification to the planning and building director for a reduction or increase in parking space requirements. The director will consider and act on this request concurrent with and as part of the full development plan or subdivision plat application process.

F. Appeals. Any applicant or affected party aggrieved by a decision of the planning and building director may make an appeal to the board of adjustment within 30 days of the date of the director's decision.
