Posted: 01/23/02 4:30 p.m. lh TOWN OF ORO VALLEY COUNCIL COMMUNICATION MEETING DATE: January 28, 2002 TO: HONORABLE MAYOR& COUNCIL FROM: Robert Conant, Planner II SUBJECT: STUDY SESSION ORDINANCE (0) 01- , OV7-00-02 AMENDING CHAPTER 11 OFF-STREET PARKING AND OFF-STREET LOADING BY DELETING SAID CHAPTER IN ITS ENTIRETY, INSERTING A NEW CHAPTER 27 DEVELOPMENT REGULATIONS SECTION 27.6 OFF-STREET PARKING AND 27.7 OFF-STREET LOADING, AMENDING ALL REFERENCES TO CHAPTER 11,AMENDING CHAPTER 2 DEFINITIONS, AMENDING CHAPTER 9 CONDITIONAL USE REGULATIONS, AND AMENDING ARTICLE 16-1 DESIGN GUIDELINES BACKGROUND: Staff proposes the amendment for the following reasons: • To reduce the number of categories for parking ratios. The current code has 53 categories; the amendment proposes 20 categories. • Remove from the Parking Code all detail standards relating to landscape and lighting. These standards will be amended and placed within the Landscape and Lighting Codes. • Develop criteria for shared parking. (Multiple uses share the same parking to reduce the total number of parking spaces). • Develop an Alternative Compliance Section, which will allow a proponent to propose an alternative to the standard parking requirements that improve the parking/design. • Reduce bicycle-parking requirements and provide incentives to promote bicycle parking. • Develop better design and improvement standards for parking lots. SUMMARY: Size of Parking Lots: The proposed code uses standards that are ratios of parking spaces to square footage of building. To help eliminate the "great seas" of parking that are typical of suburban shopping centers staff proposes maximums to these ratios (the current code provides minimums). Visibility of Parking Lots: In several jurisdictions such as Fort Collins, Colorado and Scottsdale, Arizona, a growing practice is to try and place the building(s) closer to the street with parking located on the sides and to the rear. The point of this is to reduce the visual dominance of the parking areas, to create an environment, which is more"friendly"to the pedestrian (distributed parking reduces walking distances), and to encourage the public use of the backs of buildings so they are better designed. Based on the above, the above, the parking code requires "No more than TOWN OF ORO VALLEY COUNCIL COMMUNICATION Page 2 of 4 fifty (50%)percent of the off-street parking area be located in front yard (see definition front yard OVZCR Chapter 2)." This can be accomplished in both large and small developments. Examples are provided below: • Shopping malls generally have parking on all four sides with multiple entrances. Loading zones are integrated into the design of the building in such a manner that they do not interfere with vehicle or pedestrian traffic. • If the retail development that is only a single building can distribute parking to least one side of the building as well as in the front, thus providing two other sides for drive in windows or service vehicles. Alternative Compliance: The proposed code also includes and alternative section(Section 27.6.C.2) which can be implemented where the applicant can present a creative parking design that is equal to or better than what is required by the code. Staff is aware that"one size fits all" is not the best rational for parking lot design. This alternative is suitable for unique situations and to foster positive design. Parking Lot Layout: The most efficient use of space is obtained when parking stalls are laid out perpendicular to the aisle (90 degrees). This plan provides more stalls per 100 linear feet and permits parking and unparking in either direction. Angled parking yields fewer stalls for a given length of parking (7 per 100 linear feet at 45 degrees) and permits parking and unparking in one direction only. However, angle parking uses a smaller aisle width because the traffic is in one direction and is more convenient to maneuver in and out of angled stalls; angled stalls also make it easier to spot empty spaces. Using the Foothills Mall as a comparison of 45 degree vs. 90- degree parking is shown in the table below. Parking Type Number of Spaces Aisle Width Parking Depth (1 space) 45 degree 151 20 feet 18 feet 90 degree 150 24 feet 20 feet The difference in the number of parking spaces as shown in the above table is negligible for most large parking areas. Staff is aware that all sites will not be able to park their projects with angled parking because of the lot size or topographic constraints. Table 27-1 of the Parking Code provides for alternative angled parking including 90-degree. Design Guidelines: The following Design Guidelines will be deleted from Article 16-1 and inserted into the Parking Code Section 27.6.G Design and Improvement Standards: TOWN OF ORO VALLEY COUNCIL COMMUNICATION Page 3 of 4 • Section 16-103(F)(3)(a)Discourage loading and/or servicing between building and street unless approved by DRB. Most design for loading areas become integrated into the building and are screened as required by the landscape code; therefore, this item has over time become more than just a guideline and by inserting it into the code it becomes an absolute. • Section 16-103(F)(6)(e) Control speed by appropriate internal circulation design (versus speed bumps). By inserting traffic calming measures in the code, it provides an opportunity for the Town and the applicant to build pedestrian friendly parking areas as opposed to going back after construction and building speed bumps etc. • Section 16-103(F)(6)(0 Consider decorative paving at major intersections, entries and other visually important locations. By requiring this item at the design stage of a project it will act as a traffic-calming device and add aesthetic features to the parking area. Most major commercial developers do this as a matter of course, because it creates safe passage for pedestrians into the project. • Section 16-103(F)(7)(a) Design pedestrian circulation systems in tentative development plans and preliminary plats to provide the space and alignment for walkways necessary to encourage pedestrian activity. In most commercial developments, this is considered up front and designed into the plan. Pedestrian circulation has become very important to most commercial developers because in some cases people do walk and/or ride bikes to the shopping center. The larger the development with more stores and the larger the parking area the more important it is to design pedestrian circulation from the parking areas to the center for convenience and safety. The following are considered design ideas but not necessarily a requirement; therefore, are to be inserted into Article 16-1 Design Guidelines: • Section 16-103(F)(4) new subsection (h) Encourage appropriate spacing for shopping cart bays. Most supermarkets and big boxes (Wal Mart, Target etc) provide space for shopping carts in parking areas, by writing this suggestion into the design guidelines it will give each applicant of at least large shopping centers where carts are used the incentive to provide such spaces. Planning and Zoning Commission Study Sessions: The Planning and Zoning Commission held a Study Session on September 20 and October 2, 2001, related to the proposed Parking Code. The following two issues were raised and responded to at the two study sessions: TOWN OF ORO VALLEY COUNCIL COMMUNICATION Page 4 of 4 1. Concern for holiday shoppers not being able to find parking based on the criteria used to determine parking ratios in the new code. Response: Standards for parking ratios are based on national standards (ULI) and if more parking is desired than what is required by the standards, the alternative section of the code may be implemented to provide for such adjustments if warranted. 2. Concern raised on the requirement that only 50 percent of the parking only be allowed in the front yard of a non-residential building. Response: Commercial and other non-residential structures can be constructed with two entrances; office buildings usually are. Based on the Fort Collins, Colorado model where this provision has been in place for about 10 years, the businesses and developers found that distributed parking provides good customer service through better access. Attachments Parking Code Planni • oning Administrator ommu ty Development Director 044/440/4. — Town Manag CHAPTER 27 GENERAL DEVELOPMENT REGULATIONS SECTION 27.6 OFF-STREET PARKING A. Purpose This section establishes requirements for vehicle and bicycle parking consistent with the objectives of the general plan and a balanced transportation system to promote public safety and environmental quality. These regulations are intended to: 1. Ensure sufficient off-street vehicle and bicycle parking facilities by establishing parking requirements for land uses. 2. Reduce the visual impact of mass"seas of parking"by distributing spaces around clusters of buildings. 3. Reduce excessive off-street parking by encouraging the shared use of vehicular use areas. 4. Promote pedestrian safety by separating vehicular use areas from pedestrian areas. 5. Encourage safe, convenient, and efficient design of parking spaces, circulation, and access areas. 6. Improve air quality by requiring paving of vehicular use areas. 7. Promote the enhancement of the community identity and the appearance of Town roadways and development areas. 8. The Town of Oro Valley, in keeping with the Federal Clean Air Act, wishes to encourage the use of alternative transportation modes such as the bicycle. Reducing the number of vehicular parking spaces in favor of bicycle parking spaces will help attain the standards of the Federal Clean Air Act, reduce impervious surfaces, and save on land and development costs. B. Applicability The provisions of this article 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 section than were required for the prior use, additional parking spaces shall be provided in accordance with the requirements of this section. No occupancy permit shall be issued until the Planning and Zoning Administrator has approved the parking requirements for the new use 3. Expansions: All projects that propose 25% or more cumulative addition or structural modifications such as changes in square footage, gross floor area,building façade, etc. shall meet the requirements of this code for the entire property. In addition, a 25% or more cumulative modification or replacement of parking spaces or parking lot area shall meet the requirements of this code. • Off-Street Parking Page 2 C. General Provisions 1.

TOWN OF ORO VALLEY COUNCIL COMMUNICATION MEETING DATE: January 28, 2002 TO: HONORABLE MAYOR& COUNCIL FROM: Judy Imhoff, Planner I SUBJECT: STUDY SESSION ORDINANCE (0) 01- , OV07-01-05, AMENDING CHAPTER 14, ARTICLE 14-2 ET SEQ. LANDSCAPE, IRRIGATION AND BUFFER YARD PLANS AND ALL REFERENCE THERETO, CHAPTER 2 DEFINITIONS, AND ARTICLE 16-1 DESIGN GUIDELINES OF THE ORO VALLEY ZONING CODE REVISED. BACKGROUND: In 1998 when the Native Plant Salvage Ordinance was last amended, the Planning and Zoning Commission initiated amendments to the Landscape Code at the request of staff. The aim of the update is to simplify the code, clarify requirements, and address inadequate standards. Staff worked with a Technical Advisory Committee to effect changes to the current Ordinance. The team included Oro Valley citizens and industry professionals. Study sessions were held with the Planning and Zoning Commission on September 21, 2001 and October 2, 2001 to discuss the proposed amendments to the Landscape Code. On December 4, 2001, the Planning Commission voted unanimously to recommend approval of the code amendment. SUMMARY: The six major categories of amendments proposed include; 1) Applicability, 2) Off-Street Parking, 3) Screening Requirements, 4) Addendum A, Oro Valley Approved Plant List, and 5) Design Guidelines, and 6) Buffer Yards. A summary of each is provided in the following: Applicability The code amendment will apply to all new buildings, new uses of land including subdivisions and any additions to existing building square footage and uses in every zoning district. The only exception is that of individual lots in residential subdivisions. As currently written, the existing code allows for the waiver of Landscape, Irrigation and Buffer Yard Plan submittal for any proposed R1-20, R1-36, R1-43, and R1-144 subdivisions, at the discretion of the Planning and Zoning Administrator. This provision has not been used in the past five years. The amendment eliminates the waiver allowance. Off-Street Parking As part of the amendment, landscape requirements associated with off-street parking were eliminated from the parking code and added to Section 14-204. Staff also transferred the landscape requirements contained in the commercial code and added them to the amendment. However in doing so, staff realized that numerous overlaps, as well as discrepancies exist within the screening/landscape requirements contained in the three code sections. These overlaps and discrepancies were eliminated throughout this revision; thereby, further streamlining the amendment. F:\OV\OV7\2001\07-01-05\TC Rprt Jan.28 2002.doc • 4 Screening Requirements Staff has revised Section 14-204 to include a higher degree of specificity regarding the screening devices to be used. Accompanying Table 5, Required Screening, the amendment provides that screening devices shall be masonryconstruction and/or earthen berm (3:1 slope) that provides an opaque screen, 5 feet in height. Because staff was concerned that such opaque screens may result in long, monotonous walls, a provision was also included to ensure that the screening devices would be varied. The provision provides that all masonry walls, greater than 40 feet in length shall be broken by using a combination of at least two of the following: 1) decorative caps, patterns, and variations in texture or pattern, 2) use of swales, berms and landscaping, 3) undulations or offset areas, and 4) varied setbacks. In addition, the amendment provides the Development Review Board the authority to lower/increase the height of the screening device or to waive the screening requirement. This authority is provided to resolve situations where the buffer yard, topography or layout of the development does not require screening, does not adequately screen surrounding properties or creates an unsafe, unusable landscape alley between two walls. Addendum A Thep roposed amendment includes a revised Addendum A, Oro Valley Approved Plant List. The list is featured in a table format, providing expanded information on each plant such as; plant status (tree, shrub, accent, annual, perennial, etc.),plant origin, approximate watering needs and hardiness. Design Guidelines Two landscape design guidelines have been added that would help promote water conservation and superior irrigation design. Buffer Yard Options Section 14-204 requires buffer yards in all zoning districts, as well as properties abutting perimeter streets/rights-of-ways. An opportunity to modify buffer yard requirements has been provided to the Planning and Zoning Administrator in cases where conflicts between the landscaping and traffic sight visibility occurs. In addition, the buffer yard requirements have been simplified by reducing the number options of buffer yards from 27 (as provided in the current code) to a total of seven. Those eliminated include options that were five and 7.5 feet in width. The options as amended consist of the following: • Option A,which includes of a choice three minimum widths (10', 15' and 20') • Option B, which includes a choice of four minimum widths (15', 20', 30', 40'). The number of trees, shrubs and accents varies with each buffer yard width and the largest buffer yard in each option is designated as natural desert. However, the amendment includes a provision to allow supplemental plant material in these areas to ensure effective buffering. The provision specifies that the "natural desert buffer areas" provide at least three trees and 15 shrubs per 100 linear feet. In addition the provision requires that any landscape added to meet this requirement be grouped to buffer existing uses and to minimize disturbance for planting and irrigation. Finally, street frontage buffer yards with varying widths have been provided for residential and commercial uses. F:\OV\OV7\2001\07-01-05\TC Rprt Jan.28 2002.doc { 4, During process rocess of revising the buffer yard requirements, the applicable zone districts were realigned to ensure that like zone districts were grouped together. The districts were organized with regard to the following themes: 1. Abutting zoning districts of similar intensity do not need buffer yards. 2. When a zoning district abuts another of dissimilar intensity, then a buffer yard is required. AMENDED CODE: ZONING DISTRICT OF PROPOSED DEVELOPMENT R1-144, R1-72, R1-43, R1-36, R1-20 R1-10, R1-7, R-4, SDH-6 R-4R, R-6, R-S, P&OS, PS&C C-N, C-1, C-2, T-P, P-1 Finally, the amendment provides that when the second property of two adjacent parcels is to develop, the second use is not required to provide screening over three feet high if screening has been provided by the first use. This provision eliminates the potential for two adjacent property line walls to create an "alley" or walled buffer yard. PLANNING & ZONING COMMISSION ACTION: On December 4, 2001, the Planning & Zoning Commission voted unanimously to recommend approval of the amendment to Chapter 14, Article 14-2 et seq., Landscape, Irrigation and Buffer Yard Plans.

LANDSCAPE, IRRIGATION AND BUFFER YARD PLANS SECTION 14-201 Purpose Thep rovisions set forth in this Article are designed to provide standards for the installation of landscaping and irrigation, THE CONSERVATION OF GROUND WATER, site stabilization, revegetation and the provision of buffer yards on all development projects within Oro Valley so as to promote the general welfare of the community. The preservation and protection of existing native plants and the replanting of landscaping materials, including native groundcovers, shrubs and trees, in a manner that safeguards natural views and further facilitates the control of erosion and the reduction of glare and dust, as well as the visual softening ENHANCING of building masses. Landscaping, buffer yards, walls and screens allow for the separation of incongruous uses and for the buffering of incompatible activities. Landscaping, buffer yards, walls and screens together help to effectuate privacy, logical development and enhancement of property value. These regulations serve to protect the public health, safety and general welfare by: A. LAND VALUES: 1. Preserving the existing desert landscape and creating an attractive appearance along public streets. 2. Screening from view those uses which may be detrimental to adjacent property values. 3. Aequiring ENCOURAGING preservation of native vegetation which is an integral part of the Sonoran Desert and which contributes to property values, high quality of life and the unique lifestyle which the community enjoys. GB. ENVIRONMENTAL QUALITY: 1. Preserving native vegetation which is important in stabilizing desert soils and providing food and protection for many types of desert wildlife. 2. Requiring use of native vegetation, which is more drought-tolerant and requires less maintenance than other types of landscaping materials. 3. Contributing to the reduction of air pollution by encouraging the use of vegetation for air filtration and absorption of carbon dioxide and production of oxygen. 4. Reducing soil erosion by slowing storm runoff which increases infiltration. 1 Oro Valley Zoning Code Revised (Rev.6-30-00) LANDSCAPE,IRRIGATION,AND BUFFER YARD PLAN REQUIREMENTS 5.

Sec. 14-208 Revegetation: A. Purpose: Revegetation is required in order to restore natural vegetation and habitat and to minimize soil erosion potential of graded and/or disturbed land resulting from any permitted or non-permitted construction activity in the Town. Further, revegetation provides improved air filtration and absorption of carbon monoxide and production of oxygen and is considered an essential measure in preserving the natural resources and character of the unique Sonoran Desert ecosystem existing in Eastern Pima County. B. Graded areas that are to be revegetated according to an approved plan and shall be revegetated with species appropriate to the site and its surrounding native habitat and in conformance with the Oro Valley approved revegetation seed mixes (Addendum B). Appropriate, in this sense, means that revegetation will be done, to the extent practical, with the same species and density present on undisturbed adjacent or nearby sites. C. Acceptable revegetation includes the planting of desert trees, desert shrubs and large specimen cacti or the seeding of desert trees, desert shrubs and grasses, with an adequate density to control erosion. Seeds may be raked into the soil with appropriate mulch material or established by hydroseeding, anchored mulches or jute, rolled straw or similar material approved by the Planning and Zoning Director ADMINSTRATOR. D. The seed mixes specified in Addendum B are required for all revegetation work. Only those species that are compatible with the site, soils and conditions in which they will be planted shall be used. E. During the effective period of the grading permit, any graded area that becomes overgrown with weedy species (e.g. Russian Thistle, Telegraph Plant, Desert Broom, Ragweed, Pigweed, or Burrow Brush, to name but a few) shall be weeded in order to prevent the spread of such species onto adjacent properties. F. The survival of revegetated plant materials may be enhanced by appropriate irrigation, when practical, and other maintenance procedures needed to establish the plants. G. In the process of establishing vegetation in areas of low soil productivity, the following minimum slope and surface requirements shall be followed as pre-conditions for revegetation: 1. Slopes shall be no steeper than 3:1 unless otherwise specified in a site-specific soils report prepared by a Registered Civil Engineer and approved by the Town Engineer; 2. Slopes/surfaces shall be designed for stability; 21 Oro Valley Zoning Code Revised (Rev.6-30-00) LANDSCAPE,IRRICATION,AND BUFFER YARD PLAN REQUIREMENTS 3. Slopes/surfaces shall be designed for control of surface and groundwater; 4. Slopes/surfaces shall be designed for quick establishment of vegetation; 5. A system of bench terraces or diversions may be needed to reduce effective slope length. H. For slopes steeper than 3:1 that will not readily support soil binding plants, plant material place have toin be held with mechanical structures such as retaining walls or rip-rap in accordance reportprepared with a soils by a licensed professional engineer and approved by the Town Engineer. I. Sites that are marginal for stabilization with vegetation alone shall be successfully held in place by a combination of mechanical and vegetative means as approved by the Town Engineer. Sec. 14-209 Review Procedures A. The submittal will be checked bythe Planning and Zoning Director ADMINISTRATOR for completeness. If found to be incomplete as to those requirements set forth in Sec.14-204 through 14-206, the submittal will be rejected and the applicant notified within 10 working days of the date the plans were received.
