FINAL DRAFT Glendale Municipal Airport Design Standards 5 1.0 INTRODUCTION 1.3 MISSION AND VISION These Design Standards, guided by the Airport’s mission, vision and goals, set a course towards an elevated future at the Glendale Municipal Airport (GEU). These Standards support the Airport’s desired trajectory of development and facilitate synergy between the Airport, tenants and developers to make this vision a reality one project at a time, working together with a shared purpose. 1.3.1 The Airport’s Mission The Design Standards Advisory Group established a mission statement to encapsulate the Airport’s aspirations, and serve as a guiding precept for achieving ideal growth at the airport: Mission Statement “Glendale Municipal Airport aspires to be a premiere world class general aviation airport in Glendale, Arizona, and worldwide through providing exemplary aviation services.” The Airport’s mission establishes a broad level of intent, and all visions, goals, requirements and recommendations described in these Standards are meant to support this mission. For GEU to become a premiere world class general aviation airport, the Airport will build on its current foundation and improve its capabilities with development that promotes desirability, consistency, community connection, and quality design. FINAL DRAFT Glendale Municipal Airport Design Standards 6 1.0 INTRODUCTION 1.3.2 The Airport’s Vision The Design Standards Advisory Group developed the following set of vision statements to convey the Airport’s aspirations for the future: • To strive for higher quality design development for new and existing facilities • To articulate a modern interpretation of Glendale’s past and development that complements surrounding areas • To promote the current brand and vision for the City of Glendale • To promote a unique sense of place influenced by the Airport’s geographic location within Arizona • To establish an economically viable and socially active environment to attract corporate jets, private, and commercial aviation operations • To create a positive and memorable arrival experience Other airports were identified that the advisory group admires and wants to emulate, including Montgomery- Gibbs Executive Airport (MYF), Scottsdale Airport (SDL), and Phoenix-Mesa Gateway Airport (AZA). 1.4 INTENT These Design Standards prescribe the minimum requirements for the development and construction of improvements at GEU to ensure that new development shall be consistent with the goals and mission of the Airport. These Standards will provide direction for future development on the east and west side of the airport campus in alignment with the Airport’s and the City of Glendale’s (COG) vision and requirements while also promoting sustainable growth. This is accomplished through identifying key strategies, principles, and building standards for both new development and renovation Memorable arrival experience Attract corporate jets, private, and commercial aviation operations Unique sense of place Modern interpretation of Glendale’s past and surrounding areas Higher quality design development FINAL DRAFT Glendale Municipal Airport Design Standards 7 1.0 INTRODUCTION (tenant improvement) of existing facilities to ensure the airport’s outstanding place in American aviation for generations to come. 1.4.1 Context Users of these Standards are expected to actively seek an understanding of the airport’s multiple contexts—taking into consideration geographical, historical, cultural and industry influences—in tandem with a full perusal of this document. Attainment of this understanding is a prerequisite for successful adherence to these standards and will increase prospects of securing approval through the design review process. An overview of potential topics to investigate on an individual basis in fulfillment of this expectation—not intended to limit the scope of further research—is provided below as a starting point: Geographical Context • Arrowhead Ranch • Old Town Antique Shops • Convenient freeway access to the Loop 101 (Pima Freeway), US Highway 60, Interstate 10 (I-10) and the Loop 303 • Connection to the city core, Sports and Entertainment District, and West Glendale Development Area to serve the residential and business needs of the community. Historical Context • Agricultural history • Generational history and diversity • Growing multicultural community • Rich cultural history aids in defining the community Cultural Context • Glendale Glitters and other notable public events • Sports and Entertainment Districts acting as the new city center • Proximity to 30 million square feet of industrial economic development within the Loop 303 area Old Town Antique Shops State Farm Stadium Westgate Entertainment District Glendale Glitters Glendale Agriculture FINAL DRAFT Glendale Municipal Airport Design Standards 8 1.0 INTRODUCTION Industry Context • Inclusion of an FBO and Pilot Shop • The airport has a robust aviation business community composed of flight training, aircraft maintenance, numerous other aeronautical service providers • Inclusion of worldwide aviation business and helicopter services 1.4.2 Goals The Design Standards Advisory Group identified the following goals to support the overall vision and mission for the Glendale Municipal Airport: • Ensure quality and longevity through the use of durable, timeless materials and by thoughtful design that anticipates functional changes and development throughout a building’s life-cycle • Establish a refined design aesthetic throughout the airport campus characterized by architecture that is contextually appropriate, purposeful, and that embodies the vision for the airport. • Promote cost-effective and environmentally responsible development that reduces impact on natural resources and lowers maintenance costs • Encourage development of new and renovation of existing facilities to generate revenue and provide services for surrounding communities • Convey an appropriate hierarchy of building scale and composition based on functional zones • Create economically viable spaces within the airport campus that promote social activity and foster positive images, impressions and experiences among the general public, current users, and future tenants • Achieve a balance between campus-level aesthetic consistency and building-level expressions of creative and identifying design elements • Ensure development is compatible with Airport operations and complies fully with applicable COG, Maricopa County, Federal Aviation Administration (FAA), Transportation Security Administration (TSA), and Airport rules and regulations FINAL DRAFT Glendale Municipal Airport Design Standards 9 1.0 INTRODUCTION 1.5 MINIMUM REQUIREMENTS AND REFERENCED STANDARDS Development within the airport must comply with applicable codes and regulations of the COG, Maricopa County, State of Arizona, the FAA, the Department of Homeland Security, the TSA, and the Development Master Plan approved by the COG for the airport. 1.6 APPLICATION OF DESIGN STANDARDS These Design Standards are a very important part of maintaining the unique character of the Airport. Foremost, these standards serve as a communication tool in educating property owners and developers as to the community’s expectations for new construction or renovations of existing buildings. The accompanying narrative and illustrations have been developed to serve as a standard for the Airport in reviewing applications for construction or alterations prior to submitting for and the issuance of a building permit by the COG. These Design Standards do not apply to interior only improvements, and are also not meant to be used as a checklist for “good” design, nor are they meant to be applied in such a manner as to limit development. However, this document is to provide the regulatory authorities support to ensure that new construction and renovation of existing structures is consistent with the character-defining elements identified within this document. The Airport shall use these Design Standards to review proposed projects in a consistent, fair and equitable manner. 1.7 JURISDICTION The Airport further reserves the right to amend, supplement or revise these Design Standards at any time, at its sole discretion. It is the responsibility of each leaseholder or developer to obtain and review a copy of the applicable and most current Design Standards. These Standards shall be published on GEU’s website in the 1 https://www.glendaleaz.com/live/amenities/airport___municipal/airport_documents Airport Documents Section1. Updates will be posted to the website and notifications made to airport users and development partners as needed. These Design Standards shall be applied to future development and modifications of existing buildings or sites at the airport. New development should enhance the airport’s quality of design and improve upon the character of current structures in the surrounding area. It shall be noted that airport property will be governed by these Design Standards. In general, no construction activity related to proposed common project area shall be allowed to commence until the Airport has approved the project in accordance with these Design Standards. Required permits issued for development on the airport grounds shall comply with the decisions and regulations of the parties concerned. The Airport shall review appeals in accordance with local and governmental agency regulations.

Airside development zone standards will primarily focus on meeting the expectations of regular-use airport tenants and lease holders whereas landside development zone standards will focus on providing future developers the necessary GEU and COG visioning guidelines while contributing to the beautification of the Airport. Refer to Figure 2-1: Development Zoning Exhibit for an example of airside and landside zoning elements on the Airport. 2.1.2 Airport Master Plan The COG initiated the preparation of an Airport Layout Plan (ALP) Update and Narrative Report to provide an update to the 2009 Airport Master Plan. The ALP Update & Narrative report details what airport facilities are needed, how to finance new airport development, and when to construct proposed projects. The most recent planning process was completed in May 2018 with City Council approval of the study recommendations. More information can be found in the ALP Update & Narrative Report1. 2.1.3 Aeronautical Uses New development should use airport property only for aviation-related purposes unless otherwise approved by the Airport and the FAA. Buildings intended for aviation use are to be used for aeronautical purposes such as the storage and maintenance of aircraft in accordance with FAA guidelines. 1 https://www.glendaleaz.com/common/pages/DisplayFile.aspx?itemId=15962991 2.1.4 Suggested Setbacks Corporate Hangar Setbacks • Front setbacks: Front setbacks shall be measured from the edge of the lease line and shall be a minimum of 25 feet from said line. The front of the lease line is described as that portion which fronts or parallels the vehicle access road. • Rear setbacks/staging area: A staging area equal to or larger than the largest on-site hangar is required. The staging area shall conjoin the taxi lane and hangar to prevent obstructing the taxi lane. • Side setbacks: Side setbacks shall be a minimum of ten feet to the edge of the lease line for fire access and 15 feet for buildings greater than 30 feet high. Construction of building, refuse enclosure and parking are prohibited on the front and side setbacks. Vehicle access onto the Leased Premises shall typically be perpendicular to the vehicle access road. • Multiple Leased Premises: Where the same tenant develops more than one leased premises (i.e. two adjacent leased premises), the leased premises will be considered one leased premise with respect to setback requirements. However, utility easements shall supersede the omission of setbacks in adjacent leased premises development. • It shall be the tenant’s responsibility to replace any damaged lease line corner monuments that are disturbed. • The tenant shall be responsible for painting and maintaining an aircraft parking limit line parallel to the Taxilane Object Free Area meeting FAA standards. FINAL DRAFT Glendale Municipal Airport Design Standards 13 2.0 SITE DESIGN NORTH Figure 2-1 Development Zoning Exhibit FINAL DRAFT Glendale Municipal Airport Design Standards 14 2.0 SITE DESIGN 2.1.5 Building Separation Tenants shall comply with building separation as required by building code requirements. Lease lines shall be considered “assumed” or “imaginary” property lines as defined by the local building code. 2.1.6 Building Restrictions The Building Restriction Line as shown on the ALP will control proximity of buildings to the airfield. Additional restrictions as to height will be governed by FAA Part 77 vertical surfaces. 2.1.7 Hangar Placement and Restrictions Corporate hangars shall be located on each leased premises and it is preferred that the aircraft(s) hangar doors face the taxi lane. It is preferred that there be no hangar door dominance facing Glen Harbor Blvd or New River Road. 2.1.8 Lot Coverage The minimum lot coverage shall not be less than 65 percent of the net lot area. No minimum lot size is required but each lot must have a minimum of 25 feet of frontage on a public street. For the purpose of this section, an alley is not considered a public street. 1 https://www.glendaleaz.com/common/pages/DisplayFile.aspx?itemId=15723446 Reference COG Code of Ordinances Article 5. – Zoning District Regulations for more information. 2.1.9 SASO and FBO Minimum Guidelines FBOs and SASOs shall have adequate land, facilities, and parking to accommodate all activities. Reference the Glendale Municipal Airport Minimum Operating Standards1 concerning SASOs and FBOs at GEU. 2.1.10 Airport Impact Overlay District Refer to the COG Unified Development Code for additional requirements related to the Airport Impact Overlay District which must be considered in addition to COG zoning requirements. 2.2 SITE ELEMENTS 2.2.1 Outside Storage Area Outside Storage Areas shall maintain an attractive environment for the community and adjacent businesses while allowing the open storage of airworthy aircraft. Open storage must be accessory to the business located in hangar space. Except for storage of airworthy aircraft which has been screened from landside public view by an 8 foot high masonry wall, no airside open storage is allowed unless otherwise approved by the Airport Administrator. No landside outdoor storage is allowed. 2.2.2 Refuse & Recyclable Areas Enclosed and gated refuse areas are required for each tenant’s usage. Refuse enclosure should be constructed of concrete block and have the same material finish as a significant portion of the hangar building. The gate assembly shall be constructed of opaque materials and configured to assure the contents of the enclosure are not exposed to view. The enclosure design and vehicular access clearances shall comply with City details and requirements of the refuse collection agency. If the storage Figure 2-3 - Available Leased Areas FINAL DRAFT Glendale Municipal Airport Design Standards 15 2.0 SITE DESIGN of chemical waste is warranted, a separate secondary contamination/enclosure area, approved by COG, shall be provided. Reference the City of Glendale Engineering Standard Details1 for the COG Engineering Design Standard Detail G-934 – Refuse Collection Enclosure Design and Construction. 2.2.3 Utility and Mechanical Equipment The tenant shall be responsible for fees and permits associated with connection/hookup of all utilities (including, but not limited to, sanitary sewer, storm sewer, domestic water, fire protection, cable, television, electric, Internet and telephone) to their respective building(s) including the extension of utility mains if needed. Corporate hangars requesting water and sewer utilities must apply for and receive water and sewer permits from the COG Water Department. All monthly fees for utilities shall be paid by the tenant. Utility connections/hookups shall be coordinated with the COG and the Airport prior to installation or connection. The tenant shall be responsible for costs and construction required to tap into the existing COG water main to bring water to the leased premises. The developer is responsible for coordinating water and fire flow demands on the leased premise with the COG to ensure the existing water main is not overloaded. Should it be determined that the planned domestic water and fire flow demands are greater than the supply, the tenant shall be responsible for the cost and construction of the facilities to establish a system to meet tenants’ additional demand and flow volumes without diminishing or reducing capacity to other leased premises. 1 https://www.glendaleaz.com/your_government/connect/departments/engineering/land_development_or_improvements/engineering_ design_standards 2.2.4 Water Features Water features are required to be individually metered as part of the Arizona Department of Water Resources (ADWR). Decorative fountains are also required to be designed to implement water recirculation. Fountain/ water feature lines shall be coordinated with Civil or plumbing plans and shall be noted as such on the irrigation plan. Water features such as ponds, pools, and fountains with standing water are not appropriate landscape elements for the Airport. They shall be avoided because of their potential for attracting birds and creating mosquito breeding environments. 2.2.5 Site Sustainability Sustainable designs are encouraged including the use of recycled pavement materials. Where feasible, excavated soils, asphalts, and concrete removed during rehabilitation projects could be reused in new pavement designs, reducing waste and debris transportation emissions. 2.2.6 Pedestrian Connection Encourage people to walk by providing safe, convenient, comfortable, and efficient sidewalks. Sidewalks shall be designed to serve internal pedestrian circulation needs, including links to sidewalks within the development, along the street and transit stops. Sidewalks adjacent to streets shall comply with applicable City Standards. Sidewalks within the lease area shall connect the primary entrance of each building or each public entrance to a FINAL DRAFT Glendale Municipal Airport Design Standards 16 2.0 SITE DESIGN sidewalk adjacent to the street. Such sidewalk shall be provided along the shortest practical distance between the main building entry and public/private sidewalk. When crossing a drive aisle, a pedestrian path or sidewalk should be designated through use of a decorative material. At public entrances, pedestrian walkways shall be provided with weather protection such as canopies, awnings, arcades and trellises. Sidewalks shall be designed to be convenient, attractive, and easily identifiable by first-time visitors. Refer to Section 4.0 of these Design Standards for acceptable materials and landscaping for sidewalks. 2.2.7 Screening – Parking Area / Service Area Parking areas and drive aisles shall be screened from street(s) with a screening device, such as a masonry wall, berm or combination of walls/berms and densely planted landscaping or ‘vertical wire trellis panels’. Berm side slopes shall not exceed 4:1 (horizontal to vertical) and shall be covered with a combination of vegetative and inert ground cover. Inert ground cover should consist of large rocks and decorative decomposed granite. Screen walls shall be fully opaque masonry block walls, and depending on use, either four or eight feet in height as measured from the finished grade of the parking lot in the lease area. Screen wall design shall be consistent with proposed masonry site fences within the leased premises and must be reviewed and approved by the Airport. See Section 2.3.1 Option 2 for additional guidance regarding finish. When using a screen wall or dense vegetation there shall be a landscaped setback of at least five feet between the screen wall and the edge of the parking area when adjacent to the public right-of-way and three feet when adjacent to a private street. Screen walls located adjacent to public right-of-way shall comply with Zoning Code requirements. Unless approved by the COG, walls, fences or other screening or decorative type structures will not be installed within the limits of right-of-way. 2.2.8 Shading Shading structures in the form of landscape (trees and other vertical planting), shade sails, umbrellas, framed canopies, shelters and other roofed structures are encouraged and must be approved by COG and in compliance with Section 4.0 of these Design Standards. 2.2.9 Fuel Storage Fuel storage at the Airport shall utilize storage tank systems compliant with FAA Order 1050.15B. Storage tank systems must be constructed of double-walled fiberglass reinforced plastic certified to meet UL Standard 1316. Storage tank systems must comply with all applicable Federal, state and local requirements. Access to fuel storage areas shall be controlled through the use of fences, gates and/or locks and must adhere to NFPA- 407 sign and placard requirements. Example of masonry screen walls FINAL DRAFT Glendale Municipal Airport Design Standards 17 2.0 SITE DESIGN 2.3 SITE SECURITY Security goals of the Airport are promulgated by the: • GEU Operations • Federal Aviation Administration (FAA) • Access gates must meet the requirements of, and be coordinated with, the Airport Master Plan. Tenants shall provide a security plan to the Airport which shall be approved prior to occupying the facility. Thoughtful design and effective use of the built environment can reduce crime and enhance the feeling of safety. In new building design, Crime Prevention Through Environmental Design (CPTED) is promoted by three design concepts: natural surveillance, natural access control, and natural territorial reinforcement. • Natural Surveillance: Improve the visibility of ‘unusual users’ by enhancing the line-of-sight of ‘normal users’. All doors that are open to the outside shall be well lit or visible from the street, parking area, or neighboring uses. Parking areas, walkways, elevators and stairwells are to be visible from doors and windows. Less trafficked areas such as trash or loading docks shall have visual access with window peephole or security camera. Provide landscaping that does not obscure visibility or surveillance ability to more occupied areas. • Natural Access Control: Control site access by designing defined entrances into parking lot. Define building entrance with architectural elements, lighting or landscaping. • Natural Territorial Reinforcement: Provide ten foot minimum clear zone area along the secure perimeter to prevent climbing over walls and fences. Do not locate trees where they will potentially grow limbs inside of this ten foot clear zone. 2.3.1 Gates, Fencing, and Screen Walls Leased premises must be fenced to prevent unauthorized vehicle or pedestrian access onto the aircraft apron. Generally, fencing shall run parallel to the aircraft taxilane or apron and will extend from one hangar building to the next hangar building. Each tenant shall be responsible for fencing within their lease lines. Where the fence of a tenant does not align with the fence on the next leased premises (already developed), the new tenant shall provide fencing along the common lease line to provide continuity in fence/security. Each leased premises, or adjacent leased premises developed as one hangar structure, is allowed one vehicular gate having a minimum width of 18 feet. This gate must be closed and locked at all times when not in use. All doors that lead to the Air Operations Area (AOA) are to be controlled by at least a simple access control device such as a key, keypad, punch code, or proximity card system. A log that shows who is in possession of access control devices such as keys and proximity cards shall be maintained at all times. Safety devices that meet local fire code are to be incorporated into these systems if the door has been classified as a fire exit by the Fire Department. Fire safety devices that override an access control device must produce a loud audible alarm when activated. Pedestrian gates will not be permitted except from inside the facility. Gates, manual or automatic, must be approved by the Airport. Airside/Landside requirements: fencing separating landside & airside must meet FAA security fencing requirements. No construction or “climbable” objects on landside shall be located within ten feet of airside perimeter fencing. Gates connecting airside to landside at the perimeter fence must be access-controlled and placement/use of gates is strictly controlled by the Airport. FINAL DRAFT Glendale Municipal Airport Design Standards 18 2.0 SITE DESIGN Site elements including gates, fences, and site signage within leased premises are to be integrated with the proposed design improvements. Design of site elements should strike a balance between expressing a diverse tenant identity while supporting campus-level aesthetic consistency. Gate design must be submitted to the Airport for review and approval and must meet the following requirements: • Minimum height of 8’-0”. • Gates must be constructed of materials appropriate to an aeronautical environment. • Use of wood slats within gates is prohibited. • Design must not hinder Airport operations. • Gates within screen walls must be fully opaque to deter visibility. Site fences must be a minimum of eight feet tall and must meet the requirements of FAA Advisory Circular 150/5370-10G, as amended. Refer to Figure 2-1 to determine the required fence locations within the leased premises. Approved fence options are described below. Chain link fencing does not align with the Airport’s vision for future development and is therefore not acceptable unless expressly permitted by the Airport. • Option 1 | Steel Curved Picket Security Fence Picket fences must comply with FAA/AOA requirements. See Figure 2-3 for approved design. Standard picket fencing shall be painted black for aesthetic consistency throughout the airport property. Alternative finishes must be submitted to the Airport for review and approval. • Option 2: Concrete Masonry Block Fence Masonry fence design and finish must be submitted to the Airport for review and approval. Masonry fences must be integral in color; painted block is not an acceptable finish. Existing block fences may be painted with the Airport’s approval. Approved masonry block finishes include: (1) Echelon “Walnut Creek” (ground face), and (2) Echelon “Riverside” (smooth face). Alternative finishes must be submitted to the Airport for review and approval. Perimeter fencing may involve addressing AOA security fencing as an overall landscape plan. Typically, chain link or metal picket, the fence is a primary AOA barrier type providing site security. Within these security applications, it is recommended that concrete headers be designed on the landside of the fence line to deter tunneling underneath the fence by persons and animals. Unless walls are required for screening or security purposes, they shall be avoided. 2.4 AIRSIDE CIVIL DESIGN 2.4.1 Staging Area / Taxilane Connector The Airside component of the project must be designed in conformance with FAA design guidelines as identified in the FAA Advisory Circular 150/5300-13A - Airport Design, including the following key general design criteria. See the Advisory Circular, for more detailed information and specific FAA Design Advisory Circulars references. Figure 2-3 Decorative Security Fence - Option 1 FINAL DRAFT Glendale Municipal Airport Design Standards 19 2.0 SITE DESIGN • Taxilane: the aircraft route providing access to on- site staging area (apron) from the adjacent airfield Taxiway must be paved and striped, with width, slopes, paved or graded shoulders, and pavement section in conformance with the referenced design criteria, based on the aircraft size/type intended and projected to be using the taxilane (except as noted below). • Taxilane Safety Area: the area beyond the edge of the taxilane, to a width determined by the referenced design criteria, must be graded to specific slopes, clear of obstructions, and suitable for reducing the risk of damage to an aircraft deviating from the Taxilane. Drainage swales/ ditches and retention areas are not allowed in the taxilane safety area. • Taxilane Object-Free Area: the area centered on the taxilane, to a width determined by the referenced design criteria, must be free of vertical obstructions (switch cabinets, curbs, headwalls, river rock, culverts, fuel facilities, vegetation, etc.) • Staging Area (Apron or Ramp): the aircraft staging/parking area adjacent to the hangar must be paved, with slopes and pavement section in conformance with the referenced FAA design criteria, based on the aircraft size/type intended and projected to be using the staging area (except as noted below). The staging area consists of the paved area between the hangar and the parking limit that is usable for aircraft staging. A staging area equal to or larger than the largest on-site hangar is required. The staging area shall conjoin the taxilane and hangar to prevent obstructing the taxilane while maintaining minimum separation 1 https://www.faa.gov/airports/resources/advisory_circulars/index.cfm/go/document.current/documentnumber/150_5300-13 2 https://www.faa.gov/regulations_policies/advisory_circulars/index.cfm/go/document.information/documentID/1039843 3 https://www.faa.gov/airports/resources/advisory_circulars/index.cfm/go/document.current/documentnumber/150_5370-10 requirements to adjacent tenants’ lease lines and taxilanes, etc. as specified in the FAA Advisory Circular 150/5300-13A “Airport Design”1 (current edition). Architectural barriers (buildings, walls, bollards, gates, etc.) must separate auto parking areas and the taxilane easement to prevent unauthorized access to the taxilane. Geotechnical evaluations are required for designing airside pavement structural sections. Airside pavement design is required to follow FAA guidelines (FAA AC 150/5320-6G). 2.4.2 Taxilane and Apron Paving Construction Tenants may be required to construct an aircraft parking apron contiguous with the entire airside frontage of the proposed hangar facility. The surface course of this apron must be constructed of either asphalt or concrete paving materials and be designed in accordance with the FAA Advisory Circular 150/5320-6G “Airport Pavement Design and Evaluation2 (current edition) and the GEU ALP Update & Narrative report. The minimum apron pavement section shall be designed to accommodate 1,200 annual departures of 60,000 lb, dual wheel aircraft (based on current critical aircraft) A future runway strengthening project will increase the maximum allowable aircraft weight to 90,000 lbs (based on future critical aircraft detailed in the 2018 Glendale Municipal Airport Master Plan) or shall be consistent with the aircraft that will use the facility. Tenants shall utilize asphalt or concrete on all paved areas. All materials used in the construction of the apron pavement shall meet the requirements of FAA Advisory Circular 150/5370- 10 “Standards for Specifying Construction of Airports”3 (current edition). Aircraft parked on this apron must be FINAL DRAFT Glendale Municipal Airport Design Standards 20 2.0 SITE DESIGN parked “tail to hangar” for engine start and breakaway thrust. This requirement must be taken into consideration when establishing the layout of the apron and hangar. The apron paving must be graded to, and incorporate, drains that are connected to a tenant -installed and maintained oil/water separator. Development on the west side of the airport will be required to ensure all pavement surface drainage reaches the existing storm drain system with built in separator. Tenants shall also construct an asphalt or concrete extension of the apron pavement, designed and constructed per above, beyond the lease boundary of the leased premises to the edge of the full-strength taxilane or taxiway pavement. While the tenant will be responsible for the initial construction of this additional pavement beyond the lease boundary, the Airport will be responsible for maintenance outside the lease boundary after acceptance of final construction by the Airport. If a development project includes airside components (security fencing, apron, taxilane, etc.) contact the Airport to determine if a CSPP will be required for the project. If necessary, the CSPP shall be provided by the tenant’s engineer. Refer to the CSPP checklist provided by the Airport. 2.5 LANDSIDE CIVIL DESIGN Landside civil design is detailed in the COG Engineering Standards Manual.

Refer to the Glendale Engineering Design Standards Grading and Drainage checklists3 for compliance with codes, ordinances and standards, including maximum slope criteria. For Airside, refer to FAA Advisory Circulars4 for airside-specific design information. 2.5.3 Storm Water Retention The storm water permitting process provides a mechanism to require the implementation of controls designed to prevent harmful pollutants from being washed into local water bodies by storm water runoff. The COG is currently regulated under the Arizona Pollutant Discharge Elimination System Storm water Multi-Sector General Permit for Industrial Activities AZMSGP2010-002 (MSGP-2010) released by the Arizona Department of Environmental Quality for its storm water runoff. FINAL DRAFT Glendale Municipal Airport Design Standards 21 2.0 SITE DESIGN Retention basins shall be protected from further development and must be fully improved with landscaping, irrigation systems, lighting and such other aesthetic improvements as may be required by the COG. Changes to the retention/detention basin must be approved by the COG. Any basin which is accepted by the COG for maintenance shall be deemed public property and shall be deeded to the COG in fee simple title. If a basin is not accepted for maintenance by the COG, the developer shall be responsible for establishing some satisfactory means (i.e. maintenance agreement) to maintain the area in perpetuity. 2.5.4 Lighting Obstruction lighting, as outlined in FAA Advisory Circular 70/7460-1 or subsequent amendments thereto, shall be installed and maintained on all buildings facing the taxilane depending on the height of the building(s) and any comments received from the FAA on the Form 7460- 1 submittal. A copy of the FAA submittal and response shall be forwarded by the tenant to the Airport. Exterior lights must illuminate downward to prevent glare to the airfield, pilots and/or air traffic controllers. Exterior lighting is required facing the taxilane. The facility shall be required to provide LED outdoor lighting (high pressure sodium is acceptable where an approved LED equivalent is not available). The tenant shall submit a photometric plan for approval by the Airport/COG. Lighting should consider CPTED principles. 2.5.5 Solar Equipment Roof mounted solar equipment may be installed on buildings and hangars and do not require screening. All Solar equipment or solar panel installations require prior approval from the Airport Administrator and the Air Traffic Control Tower Manager. 2.6 PARKING, ACCESS, AND LOADING Corporate Hangars shall install and maintain vehicle parking on the leased premises in accordance with COG Code of Ordinances and Engineering Design and Construction Standards requirements. The use of public parking areas of the airport to meet parking requirements for individual buildings is prohibited. Each landside tenant shall provide a minimum of one van accessible handicapped space and one parking space per three hundred square feet of office space or one van accessible ADA compliant parking space with three standard parking spaces, whichever is greater. Each airside tenant shall provide a minimum of one parking space per six hundred square feet of hangar space. Control site access by designing defined entrances into parking lot. Define building entrance with architectural elements, lighting or landscaping. 2.7 SIGNAGE REQUIREMENTS Address numbers must be located on an elevation facing the vehicle access road and shall be a contrasting color. Size must comply with COG Fire Department and Zoning requirements. Tenant monument signage is intended only to be installed on the drive side of the building (located outside the right-of-way and site visibility triangles) and for identification purposes. Advertising of any kind, other than tenant identity, is not permitted. The size of signage shall be consistent with and in scale with the size of the building. The signage may be internally or externally lit. Per the COG Code of Ordinances, all monument/entry signage plans must be submitted for review before final design acceptance. FINAL DRAFT Glendale Municipal Airport Design Standards 22 2.0 SITE DESIGN The design of the adjacent monument signage plantings shall emphasize the sign’s visibility while embracing the Airport’s landscape theming. It is recommended that the foreground of the monument signage be designed with simple geometric patterns or rows of cacti accent and groundcover plantings. If feasible, the backdrop of the monument signage shall be designed with berming, intermixed with cacti accents and boulders. The plant sizes and heights shall be coordinated with sign panel heights above finish grade to create a harmonious relationship and ensure that plants’ ultimate mature size does not obscure or block the sign message and lighting. 2.7.1 Business Identification Signage Standards Each Leased Premises may have a maximum of two identification signs, but no more than one on the taxilane and no more than one on the vehicle access roadsides of the hangar facility. • Vehicle access road sign – Monument-type sign displaying only the company name or logo and address. • Taxilane sign – Sign shall be mounted above the hangar door displaying only the company name or logo. Font shall be limited to individually mounted letters of Lexan-type material or metal. Height: 25 feet (maximum) above ground or no closer to roofline than one-half the vertical dimension of sign. No part of sign shall extend above the roof line. • Area: One square foot per linear foot of elevation on face of building where signs are located. No additional signage area is allowed for the development of multiple adjacent leased premises. • Size: overall signage size will be considered on a per project basis. • Color: Refer to Section 3.6 for acceptable sign colors. • Materials: Refer to Section 3.7 for acceptable sign materials. • Sign shall be internally illuminated. Signage shall not include flashing lights or changing messages. • No part of signage shall be mounted or painted on rooftop or mechanical screening.

Due to the visibility of rooftops from the air, minimizing or screening of rooftop equipment is encouraged. FINAL DRAFT Glendale Municipal Airport Design Standards 23 3.0 BUILDING DESIGN 3.1 INTENT This Building Design section, in conjunction with these Design Standards, are intended to be both inspirational and practical while articulating the comprehensive vision for GEU. The intent of this section is to provide clearly defined design standards that will help ensure GEU is developed in a manner consistent with the Airport’s goals and vision for future development (as described in Sections 1.3.2 and 1.3.3) and the Airport’s mission to become a premiere general aviation airport in Arizona. The following design criteria will address building character and placement, building height and scale, building orientation, color and material palette, building elevations, and sustainable practices. Buildings within the Airport shall conform to these standards, the FAA regulations, and the specific use types allowed or prohibited by the COG Zoning Ordinances. 3.2 BUILDING CHARACTER AND PLACEMENT These Design Standards are intended to establish a cohesive building type and style throughout the airport grounds. Future buildings shall promote a unified campus character defined by timeless, aesthetically pleasing, balanced, and legible architecture in alignment with the Airport’s mission, vision and goals. Building character shall aspire for a balanced interpretation of contextual influences as outlined in Section 1.3 and aviation / technology-driven influences. These objectives are intended to attract new development at the Airport including a mix of corporate jets, private and commercial aviation operation. GEU has developed airport business along its west side properties off of Glen Harbor Blvd. Future development is planned for the east side properties, including approximately 130 acres. Each building—including development on both the east and west sides of the runway—is to adhere to these Design Standards in order to enhance the design of adjacent buildings and other Building Character Examples FINAL DRAFT Glendale Municipal Airport Design Standards 24 3.0 BUILDING DESIGN development in the immediate area. Both development sides shall have a cohesive look and complement the overall Airport campus vision. When multiple structures are planned as part of a single development, the design shall be in a compatible architectural style. Buildings shall be located on each site in a manner that is efficient, appropriate to site conditions, effective to the overall architectural composition and compatible with adjoining projects and development throughout the airport. Building placement shall address the following: • Locate buildings to enhance visibility and identity, while maintaining compatible relationships with adjacent projects and street frontages. • Arrange buildings to provide convenient access to entrances and efficient on site circulation for vehicles, pedestrians, and aircraft. • Arrange buildings to provide landscaped outdoor places for people to use during work breaks. • Develop appropriate relationships between buildings and setback areas to enhance street frontages and corners. • Consider placement of buildings to properly address unique site conditions. • Consider the potential of jet blasts in the positioning of structures. • Consider FAA security and safety regulations and the Airport’s Security Program in the design. 3.3 BUILDING HEIGHT AND SCALE 3.3.1 Height Restrictions Height of buildings shall support safe airport operations and shall neither obstruct critical visibility corridors 1 https://oeaaa.faa.gov nor imaginary airspace surfaces as outlined in 14 CFR Part 77, and the Airport Master Plan (May 2009). In addition to regulating finished building height, these height restrictions shall apply during construction to temporary structures and equipment in use. When required by 14 CFR Part 77.9, Form 7460-1 Notice of Proposed Construction or Alterations, must be submitted by the tenant or developer to the FAA. Before a permit can be issued by the COG, 7460 approval is required. Furthermore, building height shall conform to COG zoning requirements and is subject to approval by the COG. A permit is required for all construction. Tenants shall seek approval in writing from the Airport prior to locating and installing satellite dishes on airport property. Satellite dish mounting height shall be reviewed for approval by the FAA through the 7460 process. For additional information on the 7460 filing process, visit the FAA’s Obstruction Evaluation / Airport Airspace Analysis website.1 3.3.2 Building Scale Development schemes that exhibit abrupt shifts in scale are less likely to secure approval from the Airport unless such bold jumps in scale are planned and integrated as an overall design strategy and display merit as a design concept with quality of materials and quality of proportioning. Building scale integrated as a design strategy FINAL DRAFT Glendale Municipal Airport Design Standards 25 3.0 BUILDING DESIGN Because of the large size of many existing buildings and the potential for many new users within the airport requiring large structures, great design skill will be required to modulate between the starkness of massive scale and the need for comfort of human scale. Where primary and secondary building functions necessitate contrasting building scales (e.g. an aircraft hangar with adjoining office space) opportunities to vary scale of exterior architectural elements relative to function shall be explored. To ensure approval by the Airport, it is recommended that standalone elements constructed of masonry or concrete achieve depth and mass wherever possible. Examples include freestanding walls, colonnades, signage pylons, and other architectural elements. 3.4 BUILDING ORIENTATION Relevant factors to consider in building orientation shall address, but are not limited to, the following: entry location, approaches from landside and airside, daylighting, climate implications, natural ventilation, energy efficiency, and potential for future expansion. Placement of windows and doors shall take into consideration optimal solar orientation to reduce heat gain and improve energy efficiency. Where site conditions require openings at the western and southern elevations, screening elements to mitigate solar impact are encouraged. Buildings shall be oriented so that primary entrances are clearly visible from the street-side approach, while service-type entrances shall be located beyond public view. Service entrances shall face away from the street- side approach wherever possible, or shall be otherwise screened through use of appropriate architectural or landscape features. 3.5 BUILDING ELEVATIONS Design of building elevations will be the primary vehicle for accomplishing a unified campus character defined by understated, straightforward, and timeless architecture. Exterior building elements shall exhibit high-quality, durable finishes and thoughtful attention to design and aesthetics. Exterior materiality and finishes shall adhere to a consistent campus color palette as outlined in Section 3.6. Design of elevations shall exhibit legible compositions that support intuitive wayfinding and convey clear public-to-private hierarchies. While these Design Standards are intended to establish consistency throughout the airport property, creativity and exploration of unique and identifiable character at the project level is encouraged. Buildings are to be designed with four-sided elevations, with detailing on each side. Building design for each facility is to be broken down by front elevations (F), side elevations (S), and rear elevations (R) as illustrated in Figure 3-1, and will follow different criteria based on the Personal Scale Airside Scale FINAL DRAFT Glendale Municipal Airport Design Standards 26 3.0 BUILDING DESIGN building orientation. Front elevations are described as that portion which fronts or parallels the public right-of- way. Side elevations are to be utilized for staging areas, back-of-house, service-type uses. Rear elevations are airside facing elevations to be treated similarly to front elevations where visible from airside public areas and approaches. Where out of public view, rear elevations may be utilized for staging areas, back-of-house, service- type functions. For buildings designed at an angle or with multiple facades, each elevation facing the public right- of-way are to be considered front elevations. On corner lots, the elevations facing both public streets are to be considered front elevations. Building elevations must conform to FAA requirements and shall be reviewed by the Airport for adherence to the mission, vision, goals and intent set forth in these Design Standards. As a general rule, building finishes visible from both landside and airside public approaches shall exhibit higher quality finishes and design. Materials are not to come to an abrupt end at corners of buildings, it shall continue to wrap around the corners of the building and gradually taper down. Hangars visible from the public street are recommended to utilize an increased landscape plan along the street frontage. Building elevations with large expanses of repetitive elements or continuous application of color or materials are discouraged and shall not be appropriate for neither landside nor airside public-facing elevations. Thoughtful variation in color, texture, composition, and scale is the recommended design approach for elevations, with emphasis on public-facing elevations. Window treatment used shall assist in giving the buildings an appropriate scale and help identify the use. Building entryways shall be designed and placed as an integrated element of the overall design. Obvious identification of entryway and sufficient lighting shall be incorporated. Entry canopies are encouraged to provide an inviting, unique aesthetic that can help orient visitors to locate building entrance(s) while protecting from weather conditions. Building-mounted mechanical and electrical equipment shall be screened from view. Screens shall consist of architecturally suitable material compatible with the design, materials and color of the main structure. Due to the visibility of rooftops from the air, minimizing or screening of rooftop equipment, including solar devices, is encouraged. Additionally, exterior storage and other service areas are to be visually screened. Proposed screening is subject to approval by the Airport.

The color palette was inspired by the airport’s surrounding context and aspirations to develop into a modern, jet-oriented campus. The palette includes timeless neutral tones for field application relating to aviation and the desert landscape. A selection of accent colors are also included, derived from the airport’s prominent blue skies and Glendale’s agricultural history. Thoughtful innovations within this color family are encouraged, while garish and self-aggrandizing schemes will be rejected. The intent of this color palette within the Design Standards is to provide tenants with general guidance towards and acceptable range of color selections. When color choices are made, design elements expressive of a building’s character shall receive special care in color selection and are easily deserving of the use of a strong color, however they are accents; be strong but sparing in volume and quantity. For large expanses of building skin or aspects of the building that are fundamental, color choices shall reflect the intent to prevent structures from becoming visually outdated. Colors within the palette suggested for field and roof application are intentionally neutral shades to demonstrate this intent. Paint color placement shall prevent accent bands and stripes along building facade. Solid color application through paint and materials are encouraged in volumes and masses. Color change via material change is also acceptable.

The material palette shall display a strong balance between economy and quality expressions of building development. On large buildings, a majority of economical materials is expected, but punctuated and well articulated use of prestige materials to accentuate the building must be a strong accompanying presence. Design shall reach a natural balance between quality treatments and economy materials that in no way are intended to replace the need for quality architectural services and experienced professional design. It is recommended that each design submittal express an overall thematic development in the use of materials. For example, if brushed aluminum is selected as an accent material to be played against an overall theme of split face masonry, this interplay should be expressed thematically throughout the entire project. The type of building materials used shall be resistant, reliable, withstand weather conditions, require low maintenance, be durable and be an asset to the overall Airport image. Materials selections shall be mindful of anticipated use patterns given specific application areas and shall exhibit resistant qualities in high-use areas to prevent general wear, impact damage or potential vandalism. Material selections at hangars shall be appropriate for anticipated exposure to caustic or hazardous substances and shall be designed to resist aircraft jet-blast. The use of reflective surfaces and mirrored window glazing is prohibited, and all metal finishes must be incorporated into the structure in such a way as to pose no glare or reflection that is hazardous to flight operations. 3.7.1 Acceptable Materials The following materials are acceptable for future development at the Airport campus following the applications described herein. When materials are appropriate only at specific elevations, those elevations are designated using the labels F, S, and R—front, side and rear elevations, respectively—corresponding with building locations illustrated in Figure 3-1. If a specific elevation is not identified, it may be assumed that the material is acceptable for use at all building elevations. Color selections of materials shall complement the color palette provided in Section 3.6. • CONCRETE - Prefabricated, tilt-up and cast-in place concrete are acceptable for use in walls. Concrete roof tiles are acceptable. If concrete is to have a colored finish, it is highly recommended that concrete be integrally colored with matching joint sealant. Examples of tilt-up concrete buildings FINAL DRAFT Glendale Municipal Airport Design Standards 30 3.0 BUILDING DESIGN • MASONRY - Including concrete masonry units (CMU), brick, and stone veneers (F). Brick is to be applied in modern application without being the predominant material. Finish: integrally colored or textured and constructed with integrally colored mortar. Painted CMU is discouraged. • GLAZING - Insulated glazing units with aluminum storefront or curtain wall. • METAL - Includes aluminum composite material, premium metal wall systems, corrugated metals (R/S). Finishes: stainless steel, aluminum, and other premium metals.

The GEU has not developed a sustainable design approach nor standards, but it is strongly recommended and encouraged for projects to explore sustainable design strategies. To minimize environmental impact and promote sustainable design alternatives, the following approaches and strategies shall be taken into consideration. Refer to Sections 2.2.5 and 4.6 for additional guidance on sustainable approaches. Sustainable Sites: • Reduce the heat island effect through landscaping and reflective materials • Prevent construction activity pollution by controlling dust and erosion Water Efficiency: • Offset potable water consumption through the recovery and reuse of rain and site water in non- potable applications such as site irrigation • Reduce outdoor water use by utilizing efficient irrigation technologies Energy & Atmosphere: • Increase the energy efficiency of the building to reduce the overall energy consumption through the means of higher efficient mechanical equipment, higher insulation value, and minimize solar heat gain/loss • Use of on-site or renewable energy to power the building. For example, utilize photo-voltaic and wind turbines to generate on-site energy Materials & Resources: • Provide for on-site storage and collection of recyclables • Use regional materials in the construction of the building • Use renewable / recycled construction materials • Divert construction and demolition waste from landfills and incineration facilities by exploring alternatives to recover, reuse or recycle materials Indoor Environmental Quality: • Minimize exposure of building occupants to Environmental Tobacco Smoke • Use low-emitting materials in the construction • Provide controllability of thermal and lighting systems for building occupants • Provide design spaces to maximize natural daylight and view opportunities Detailed descriptions of sustainable features planned to be utilized in new facilities shall be provided to the Airport for review. LEED certification checklists shall be submitted if LEED certification is to be pursued. Sustainable applications are subject to the regulations and approval of the FAA, the authority having jurisdiction, the Development Services Department (DSD) and the Airport. FINAL DRAFT Glendale Municipal Airport Design Standards 32 4.0 LANDSCAPE DESIGN 4.1 INTENT The landscape is a unifying element that strengthens the overall quality and character of the Airport. The primary vision for the Airport’s landscaping is to create a contemporary hospitality theme that promotes a sense of “arrival” to a welcoming desert environment. 4.2 GOALS AND OBJECTIVES The following goals, which meet current COG policies and support the Airport’s overall vision, apply to all landscape improvements associated with the development of sites on the Airport campus: • To promote safety and security for pedestrians, facility functions, and aircraft traffic. • To create an enhanced landscape setting that creates a long-lasting impression and sense of place for visitors, tenants, and the Glendale community. • To establish a sustainable site that is well designed and maintained, using low-impact development where possible. The landscape design standards will accomplish these goals by meeting the following objectives: • Planting in AOA’s shall be avoided or minimized. Plants shall be primarily utilized within “landside” areas, including right-of-way areas, property buffer areas (required setbacks), parking lots, retention basins, and building foundation areas. • The landscape layout and plant palette shall reduce wildlife attractants and wildlife hazards. • The landscaping shall emphasize natural shade to reduce the Valley’s heat island effect. • To maintain applicable clear zones and reduce maintenance, the landscape design shall consider the mature size of each plant. • The landscape layout and plant palette shall be used to promote desirable airport views such as building architecture, monument/wayfinding signage, and screen undesirable views such as service areas, parking lots, and above-ground utilities. • The planting layout may also reflect the COG’s agricultural background using recommended plant material laid out in rows and plots. • The plant palette shall highlight cacti and succulents, their unique forms creating a strong visual statement, as well as shrubs and groundcovers to provide colorful, seasonal blooms. • The landscape shall support sustainable sites through maintenance best practices, efficient irrigation techniques, designing with arid-adapted plants, and incorporating water harvesting techniques.

Aesthetically, the landscape design shall reflect a contemporary hospitality theme with the following features: • Cacti, including accents, shall be significant elements of the landscape palette. • Understory plantings shall occur in simple and repetitious massing. • Boulders shall be placed to appear natural in berms or higher profile landscape areas. • Adjacent to buildings or structures, clean, sharp lines or geometric patterns shall be used within the hardscape and planting areas to reinforce, interpret, or replicate the architectural forms, aviation theme, and historical agricultural practices. • Trees shall be used to shade landside pedestrian walkways, plazas, courtyards, and other public spaces. The landscape design shall satisfy minimum requirements of Chapter 19 of the COG’s Code of Ordinances while addressing the Design Standards within the site zones as shown in following subsections. Landscape Massing Landscape Massing Contemporary Layout FINAL DRAFT Glendale Municipal Airport Design Standards 35 4.0 LANDSCAPE DESIGN 4.4.1 Street Frontages and Right-of-Way Areas The landscaped areas along street frontages shall embrace continuity between each property. The tree types and understory planting layout shall blend with the adjacent landscape. The tree spacing shall be consistent and allow for view corridors onto significant site features. Contouring or berming is recommended to provide variations in grade, visual relief, screening of parking lots and service areas, and a more pleasing landscape aesthetic. Understanding mature plant height is crucial when designing or maintaining plants within sight-visibility triangles. Plantings within these areas must comply with the COG’s sight distance requirements. Shrubs, cacti accents, groundcover, boulders, berms, walls, or other such materials within sight-visibility triangles shall not exceed a height of 18 inches to avoid blocking views of drivers, pedestrians, and cyclists. Trees with a clear canopy distance of 84 inches are permitted within the sight visibility. In conformance with the COG’s Chapter 19 Code of Ordinances, the layout, components, and maintenance of the landscape and irrigation design within the off-site and right-of-way areas shall meet the COG’s Engineering Design & Construction Standards for design requirements. 4.4.2 Parking Lots By implementing the COG’s landscape requirements, landscaping in both the perimeter parking areas and within parking lot islands is used to break up the expansiveness of pavement. The location of landscape islands shall support efficient parking, vehicular circulation, and safe pedestrian access from the parking lot areas to the building entries. The landscape treatment between the parking lot edge and the sidewalk/street right-of-way can be an environmental asset and visual amenity. This area shall screen parked vehicles but not completely obstruct views into and out of the parking lot for pedestrian safety. Screening can consist of continuous planting or combination with low decorative walls or decorative fences or berms to a minimum height of four feet. Narrow landscape areas such as these are prime opportunities for incorporating LID features and techniques, such as bioretention basins. Street Frontage and Right-of-Way Landscape Character FINAL DRAFT Glendale Municipal Airport Design Standards 36 4.0 LANDSCAPE DESIGN Safe access of pedestrians shall be integrated into the parking lot design. Walkways shall provide convenient access from the street frontage and interior parking areas to building entrances. Safe pedestrian routes are accomplished by separating the pedestrian areas from vehicles, particularly in locations with significant vehicle traffic. This can be achieved by using landscape islands and medians for pedestrian walkways, separating cars from pedestrians along driveways, and providing pavement striping and markings, especially for persons with disabilities. Generous tree islands and vegetative buffer areas incorporating pedestrian pathways can provide safe` and attractive pedestrian routes through parking lots and provide opportunities for incorporating low-impact development features. If feasible, it is encouraged to utilize best practices in stormwater management and permeable materials to reduce the impact of the parking lot. 4.4.3 Perimeter Landscape Buffers (Required Setback Areas) Landscape buffers are required when property lines are contiguous with other commercial or industrial properties. Where the unattractive site and building elements need to be screened, dense landscaping and vertical landscape elements can provide the necessary visual separation without compromising security. Examples of site features that often need screening include but are not limited to storage areas, standalone unfinished or untreated trash enclosures, mechanical equipment, transformers, backflow devices, and other similar elements. 4.4.4 Landscape Adjacent to Buildings (Landside Only) The landside landscape near the building shall feature a simple palette with plant massing that complements the architecture’s scale, color, patterns, and forms. The use of larger specimen cacti accents intermixed with boulders and seasonally colorful groundcover shall reinforce wayfinding and public access. For safety, avoid placing cacti with thorns or spikes within three feet from the edge of sidewalks and other high-traffic public spaces. 4.4.5 Air Operations Area The landscape shall not negatively impact aircraft operational safety or increase aircraft apron, taxiway, or runway maintenance. A secure clear zone is required for all landscape areas along the AOA fence line. The clear zone shall include a minimum ten-foot landscape border on the landside of the fence and shall be free of any climbable objects, including trees and larger shrubs or cacti accents. These clear zones shall be installed with plants under 18 inches in mature height. 4.4.6 Future Development Areas In areas where future phases of development are planned or with undeveloped parcels, an interim landscape shall be established for dust control and a consistent visual landscape approach to the site. To meet minimum requirements, decomposed granite shall be applied to these areas. To prevent weed growth, a pre- emergent herbicide shall be applied to the ground before and after placing the decomposed granite materials. Landscape Adjacent to Building FINAL DRAFT Glendale Municipal Airport Design Standards 37 4.0 LANDSCAPE DESIGN 4.5 PLANT LIST AND LANDSCAPE MATERIALS The recommended plant lists support establishing consistency in landscape quality while maintaining and enhancing the character throughout the Airport. Plant materials that are not on this list but are found on the ADWR Low Water Use List and meet the COG’s requirements may be considered for use on a case-by- case basis during the Airport’s Design Review Process. 4.5.1 Trees Trees help define outdoor spaces through their vertical form and lush canopies. Mature shade trees are an essential component of the Airport’s landscape character because of the shade they cast, which helps cool local temperatures and soften the visual environment from their leafy texture and green color. It is recommended to select thornless tree varieties for landscape areas where there is public interaction, such as parking lots, walkways, seating areas, and general entries. The following list includes the trees that have been identified as suitable for use. This list provides a diversity of forms, colors, and textures for use in various projects and contexts. • Acacia aneura Mulga • Caesalpinia cacalaco Cascalote • Ebenopsis ebano Texas Ebony • Parkinsonia florida Blue Palo Verde • Parkinsonia microphylla Foothills Palo Verde • Pistacia x ‘Red Push’ Red Push Pistache • Prosopis hybrid ‘thornless’ Hybrid Mesquite • Quercus fusiformis Joan Lionetti Oak • Vitex agnus-castus Chaste Tree Mulga Tree Red Push Pistache Chaste Tree FINAL DRAFT Glendale Municipal Airport Design Standards 38 4.0 LANDSCAPE DESIGN 4.5.2 Shrubs/Ornamental Grasses Shrubs provide screening, borders, year-round and seasonal colors and accents in a wide variety of shapes and sizes. The following shrubs are known to thrive in the Phoenix area. • Alyogyne huegelii Blue Hibiscus • Chrysactinia mexicana Damianita • Calliandra californica Red Baja Fairy Duster • Caesalpinia pulcherrima Red Bird of Paradise • Dodonaea viscosa Hop Bush • Eremophila maculata Valentine Emu Bush • Ericameria laricifolia Turpentine Bush • Encelia farinosa Brittle Bush • Justicia spicigera Mexican Honeysuckle • Leucophyllum species Sage • Muhlenbergia capillaris Pink Muhly • Muhlenbergia rigens Deer Grass • Nolina microcarpa Beargrass • Ruellia species Ruellia • Simmondsia chinensis ‘Vista’ Compact Jojoba • Tecoma stans Arizona Yellow Bells 4.5.3 Vines Vines are appropriate where the limited area is available for planting between walls, sidewalks, and structures. When supported on structures, vines can provide screening, cover, and visual interest in these cases. • Bougainvillea spectabilis Bougainvillea • Hardenbergia violacea Lilac Vine • Macfadyena unguis-cati Cat Claw Vine • Merremia aurea Yellow Morning Glory • Bignonia capreolata Cross Vine Yellow Bells Ruellia Sage Red Bird of Paradise Lilac Vine Bougainvillea Compact Jojoba Regal Mist Valentine Emu Bush Cross Vine FINAL DRAFT Glendale Municipal Airport Design Standards 39 4.0 LANDSCAPE DESIGN 4.5.4 Accents Accent plants are unique and distinct in the desert Southwest and can provide dramatic visual interest and bold contrast, especially with complex backdrops such as walls and buildings. Many plants native to the Southwest, such as agave, yucca, and cactus species, have beautiful sculptural forms and colorful flowers that add value to the Airport’s landscape. • Agave species Agave • Aloe species Aloe • Asclepias subulata Desert Milkweed • Carnegiea gigantea Saguaro • Cereus hildmannianus Hildmann’s Cereus • Dasylirion wheeleri Desert Spoon • Echinocactus grusonii Golden Barrel Cactus • Echinopsis pachanoi San Pedro Cactus • Euphorbia antisyphilitica Candelilla Euphorbia • Euphorbia resinifera Moroccan Mound • Euphorbia rigida Yellow Spurge • Euphorbia tirucalli Sticks on Fire Pencil Tree • Ferocactus cylindraceus Compass Barrel • Ferocactus wislizenii Fish Hook Barrel • Fouquieria splendens Ocotillo • Hesperaloe parviflora ‘Yellow’ Yellow Hesperaloe • Lophocereus species Totem Pole Cactus • Opuntia basilaris Beavertail Prickly Pear • Opuntia engelmannii Engelmann’s Prickly Pear • Opuntia santa-rita Purple Prickly Pear • Myrtillocactus geometrizans Blue Myrtle • Pachycereus marginatus Mexican Fence Post • Pachycereus pringlei Cardon • Pedilanthus macrocarpus Slipper Flower • Portulacaria afra Elephant’s Food • Sansevieria zeylanica Mother-in-law Tongue • Stenocereus thurberi Organ Pipe Cactus • Trichocereus species Cactus King • Yucca species Yucca Yellow Hesperaloe Blue Glow Agave Golden Barrel Cactus Beavertail Prickly Pear Mother-In-Law Tongue Spanish Dagger Yucca Foxtail Agave Fish Hook Barrel Mexican Fence Post San Pedro Cactus FINAL DRAFT Glendale Municipal Airport Design Standards 40 4.0 LANDSCAPE DESIGN 4.5.5 Groundcover Groundcovers are plants that spread low along the ground. These plants help shade the soil, soften the harshness of inorganic groundcovers, and reduce wind and water erosion. Groundcover plantings are essential for a well-balanced and visually attractive planting design. • Acacia redolens Trailing Acacia • Convolvulus cneorum Bush Morning Glory • Lantana hybrid Lantana • Rosmarinus officinalis Trailing Rosemary • Sphagneticola trilobata Yellow Dot • Tradescantia pallida Purple Heart 4.5.6 Inert Landscape Material The top-dressing inert material is an essential aesthetic component of the landscape and will help control dust and erosion. All landscaped areas shall be finished with a topping material of decomposed granite with a minimum two-inch depth. The recommended granular size of the decomposed granite is one-half inch screened. The finished grade of the decomposed granite shall be smooth, uniform, a minimum of one-half inch below the adjacent sidewalk or curb. A pre-emergent herbicide shall be applied to the ground before and after placing natural surface materials in any landscaped area to prevent weed growth. The placement of boulders shall be installed naturally within the landscape with a minimum buried depth of one-third the size of the boulder. 4.5.7 Prohibited Plants and Wildlife Deterrents The tenant shall avoid planting any species of tree, shrub, or plant that produces berries, nuts, or any fruit as these can attract birds or other wildlife. Palm Trees are not part of the Airport’s vision also the use of grass lawns is not encouraged and shall be used only where required or requested and explicitly approved by the COG. As a sustainable and low water-use approach, annuals and perennials are discouraged and will only be used minimally within planters or highly visible spaces. Annuals are seasonal, short-lived plants usually characterized by bright foliage or blooms. Perennials are plants that live for more than one growing season and often feature showy flowers. 4.6 SUSTAINABILITY The COG encourages the incorporation of Smart Growth and LID techniques in the right-of-way, parking lots, and landside landscape areas. The benefits of LID techniques include reducing flooding, mitigating the heat island effect, reducing sediment and pollutant loads, reducing the cost of stormwater run-off, and utilizing first flush rainwater for landscape irrigation. Existing on-site plants that may need to be cleared or grubbed shall be evaluated for their potential to remain in place or be salvaged and transplanted for use elsewhere on the project site as part of the project’s landscape improvements. Bush Morning Glory Yellow Dot Lantana Decomposed Granite FINAL DRAFT Glendale Municipal Airport Design Standards 41 4.0 LANDSCAPE DESIGN 4.7 MAINTENANCE 4.7.1 Landscape Landscape maintenance shall consider the natural form and growth habits of all plants. Proper care will allow the plants to grow to their full potential using just the right amount (and not any more) of water and nutrients needed to thrive. Maintenance best practices will reduce labor and replacement costs while reducing potential hazards from falling limbs, obscured sightlines, and unstable surfaces. After significant storm events, and at least annually, inspect grading, ground coverings, mulch, irrigation systems, and other site improvements for signs of damage or erosion. Repair or restore immediately to minimize additional damage. A well-placed landscape design with a drought- tolerant plant palette is intended to take on the natural characteristics of its component materials. It shall not be sculpted, hacked, or otherwise overmanaged. Shearing shrubs and trees into balls or geometric shapes are inconsistent with accepted best practices and can harm the plant itself. Accents such as golden barrel, mexican fence post, totem pole cactus, and prickly pear should be allowed to develop naturally, without pruning. The exception will be if the spikes and thorns of these accents are creating a safety issue. The dried flower stalks of aloe and hesperaloe may be removed if a neater appearance is desired. The emergence of a flowering stalk on agave, which resembles a spear of asparagus, signals the beginning of the end for the parent plant. The flowering stalk should be allowed to mature and bloom. 4.7.2 Irrigation Water is a precious and expensive resource in Arizona. Inefficient watering systems increase usage due to evaporation, wind, improper system design, and overwatering. It is essential to irrigate the landscape as efficiently as possible. The overall goal is to apply water only when and where required. The most effective system is a fully automated and monitored irrigation watering distribution system that communicates with central control stations in real-time. The systems shall be equipped with flow controls and master valve sensors that can shut off zones that are inoperable.

The paving colors, materials, and finishes shall address clean, sharp lines or geometric patterns that reinforce and replicate the architectural forms, aviation theme, and historical agricultural practices. The use of stamped concrete, porous pavers, exposed aggregate, or colored concrete is encouraged. 4.8.2 Site Furnishings Site furnishings include benches, trash receptacles, tables, and bicycle racks. These landscape amenities shall improve pedestrian active and passive areas with high-quality furnishings and structures that are designed to be weather and vandal resistant while supporting the architectural aesthetics. All furnishings shall be installed and anchored in permanent ground footings and provide for compliance with the Americans with Disabilities Act (ADA). Bench seating and tables shall be placed in naturally shaded areas where possible. 4.8.3 Accent Lighting Accent lighting may be provided to accent or highlight landscape areas or special features in the landscape or increase pedestrian usabilities of a particular space at night, such as vehicular drop-off areas, monument signage, public walkways, and plazas. All lighting provided shall be downward, directed, and shielded. The pedestrian bollard or light fixtures’ scale, color, and style selection shall be architecturally compatible with the modern/contemporary theme.
