11-04-08: PARKING AND LOADING:
   1.   Purpose: The purpose of this Section 11-04-08 is to establish standards for vehicle and bicycle parking, on-site circulation, loading areas, and parking lot design to protect the public health, safety, and general welfare by:
      A.   Providing necessary access for service and emergency vehicles;
      B.   Providing for safe, convenient, and comfortable interactions between motor vehicles, non-motorized vehicles, bicyclists, and pedestrians;
      C.   Encouraging active transportation options and enhanced pedestrian safety;
      D.   Encouraging emission free vehicles;
      E.   Providing flexibility to respond to the transportation, access, and loading impacts of various land uses in different areas of the city;
      F.   Reducing stormwater runoff, reducing heat island effect from large expanses of pavement, improving water quality, and minimizing dust pollution;
      G.   Mitigating traffic congestion; and
      H.   Mitigating the visual impact of large expanses of exposed parking.
   2.   Applicability:
      A.   Generally: Unless otherwise stated in this Code, the standards in this Section 11-04-08 shall apply to all uses in all zoning districts.
      B.   Exceptions:
         (1)   The MX-5 zoning district is exempt from the requirement to provide off-street parking spaces, but any parking spaces provided shall comply with all other standards in this Section 11-04-08.
         (2)   Structured parking facilities shall be exempt from maximum parking limits.
   3.   General Parking Standards:
      A.   Use of Parking Areas:
         (1)   Required off-street parking facilities shall be used for vehicle parking only. Vehicle sales, rental and leasing, storage, repair, and other uses are prohibited, except for approved temporary and/or seasonal uses.
         (2)   No property owner or operator may designate any on-street parking space for the use of a specific establishment, and no property owner or operator may limit the use of any on-street parking space by the general public by using the parking space for the operation of a valet parking service, without the prior written consent of the City.
      B.   Parking and Loading Calculations:
         (1)   All square footage-based parking and loading requirements shall be computed based on the gross floor area of the subject use or structure, unless otherwise specified.
         (2)   Parking spaces designed or designated exclusively for two-wheeled vehicles such as motorcycles and scooters shall not be included in the calculation of minimum or maximum vehicle parking requirements. However, a reduction in the minimum number of parking spaces is allowed in accordance with Subsection 11-04-08.7.C when two-wheeled vehicle parking spaces are provided.
         (3)   Lots containing more than one use shall provide parking and loading based on the shared parking calculations in Section 11-04-08.7.B, Shared Parking Facility Reduction.
      C.   Reductions of Existing Parking: Off-street parking or loading spaces existing on the Effective Date shall not be permanently reduced in a way that would bring the property out of conformance with this Section 11-04-08 or would increase the degree of existing nonconformity with the provisions of this Section 11-04-08.
      D.   Parking for Unlisted Uses: The Planning Director shall determine the required parking for uses not listed in Table 11-04.9 : Off-Street Parking Requirements, based on expected volume of activity on the site, the level of congestion on surrounding streets, proximity to Residential zoning districts, and the factors listed in Section 11-03-01 .7, Classification of New and Unlisted Uses.
   4.   Accessible Parking: All development that provides on-site vehicle parking spaces shall comply with all applicable requirements of the Americans with Disabilities Act (ADA) and the International Building Code (IBC), and the standards in this Section 11-04-08.3.

         (2)   Each EV parking space provided shall be counted towards the minimum off-street parking requirements for the project, but shall not count against any limit on the maximum number of off-street parking spaces permitted.
      B.   Adjustment Of EV Parking Requirements: When the cost of installing EV parking spaces required by Subsection (1) above would exceed 10 percent of the total project cost, the applicant may submit to the Planning Director a cost estimate for the total project and for the EV installations required by this Section 11-04-08.6 and may request a reduction in the EV parking requirements, and the Planning Director may approve an adjustment in the required numbers or types of EV parking facilities to limit installation costs to no more than 10 percent of the total project costs.
      C.   Dimensions and Design:
         (1)   All EV parking spaces shall meet the minimum dimensional standards of Section 11-04-08.
         (2)   EV charging equipment shall be designed and located so as to not impede pedestrian or vehicle travel or create hazards within the public right-of-way.
         (3)   EV charging equipment shall be designed and located to be accessible by:
            (a)   Locating each EV charging spaces on an accessible route, with an adjacent sidewalk at least seven feet wide;
            (b)   Requiring that the parking space served by EV charging equipment be a minimum of 11 feet wide and 20 feet deep;
            (c)   Providing an adjoining access aisle that is a minimum of five feet in width;
            (d)   Providing clear ground space with an unobstructed side reach at the same level as the vehicle charging space; and
            (e)   Accessible charger, connector, and other operable parts.
         (4)   Charging equipment shall be protected by wheel stops, bollards, or similar devices to prevent damage.
         (5)   Charger cords shall be retractable or have a hanging or storage locations outside of pedestrian pathways.
         (6)   Cords connecting chargers to vehicles shall not cross driveways, sidewalks, or loading areas.
         (7)   EV parking spaces with an installed Electric Vehicle Charging Station shall be signed to reserve the parking space for EV users.
         (8)   All Electric Vehicle Charging Stations shall include an emergency power shutoff located in a location easily accessible by emergency responders.
   7.   Parking Adjustments:
      A.   General:
         (1)   The minimum and maximum parking requirements in Table 11-04.11  Table 11-04.9 : Off-Street Parking Requirements, may be adjusted as described in this Subsection 7, provided that no combination of reductions in Subsections B through G shall result in the reduction of the minimum number of parking spaces required in Table 11-04.9 by more than 50 percent.
         (2)   A Conditional Use Permit is required for any request to reduce minimum parking requirements by more than 50 percent.
      B.   Shared Parking Facility Reduction:
         (1)   Where two or more uses listed in Table 11-03.1 : Table of Allowed Uses share a parking lot or garage, the total off-street parking requirement for those uses shown in Table 11-04.9 : Off-Street Parking Requirements may be reduced by the factors shown in Table 11-04.11 : Shared Parking Reduction.
 
TABLE 11-04.11: SHARED PARKING REDUCTION
To calculate the shared parking reduction, add the requirements for each use category, then divide the sum by the factor indicated below.

         (2)    To calculate the revised minimum parking requirement, calculate the minimum off-street parking requirement individually for the two uses with the highest off-street parking requirement, and then divide that sum by the number shown in the cell for that combination of uses in Table 11-04.11. For example: a development with 5,000 square feet of Small Retail space (3 per 1,000 square feet gross floor area) and 20, two-bedroom Multiple-Family Dwelling units (1.25 per dwelling unit) would take the total spaces required and divide by 1.2.
            (15) + (25+3) = 43.
            43/1.2 = 35.833
            The shared parking requirement is 36 spaces.
         (3)   If more than two uses share a parking lot or structure, the reduction factors in Table 11-04.11 are applied only to the two uses with the highest parking requirements. The minimum parking required for the third and additional uses sharing the parking lot or facility are then added to the adjustment calculated in Subsection (2) above without further adjustment.
      C.   Two Wheeled Parking Reduction: For every four motorcycle, scooter, or similar two-wheeled vehicle spaces (excluding bicycle parking) provided, the number of standard vehicle spaces required may be reduced by one, provided that each two wheeled parking space is at least four feet wide and at least 10 feet long and is clearly posted or marked as a motorcycle/scooter parking space.
      D.   Tree Preservation: The Planning Director may allow up to a 10 percent reduction of the required parking spaces to save healthy, desirable trees.
      E.   Affordable and Sustainable/Resilient Housing Reduction: Affordable housing projects meeting the affordability and/or sustainability/resiliency requirements of Section 11-04-03.7, Incentives, shall be eligible for the parking reductions as set forth in that Section.
      F.   Adaptive Reuse Reduction: Adaptive reuse projects meeting the requirements of Section 11-04-03.7.D(6) shall be eligible for the parking reductions as set forth in that Section.
      G.   Transportation Demand Management Reduction: The Planning Director may allow a reduction in required parking for employers that enter into a Transportation Demand Management (TDM) Agreement with the City that specifies how on-site parking will be reduced through property owner or operator programs or initiatives that reduce the amount of parking demand on-site. If a reduction in parking is granted through a TDM Agreement, the employer will be required to remain in good standing with the TDM Agreement and shall submit an annual report documenting the terms of the Agreement are being met. Any TDM Agreement, whether used independently or in combination with other allowed parking reductions, is subject to the 50 percent limitation on overall parking reduction. Such programs may include the following:
         (1)   Compressed work week schedules;
         (2)   Flexible arrival and departure times;
         (3)   Telework opportunities;
         (4)   Incentives for employees to use alternative modes of transportation to the workplace;
         (5)   End of commute amenities such as a locker room, changing room or shower;
         (6)   Implement/support ridesharing program (i.e., vanpool, carpool);
         (7)   Designate a Commute Coordinator (Employee Transportation Coordinator) to facilitate employee/property commute program;
         (8)   Display transportation information in a prominent location including transit routes and schedules; carpooling and vanpooling information; bike routes; and commute subsidy information;
         (9)   Provide information for new tenants and employees on transportation options (e.g., flyers, posters, brochures, onboarding information, and emails on commute alternatives); host/participate in transportation fairs, local commute events such as May in Motion or Boise Bike Week;
         (10)   Provide employee subsidies for alternative transportation;
         (11)   Provide preferred parking for carpool/vanpool;
         (12)   Provide pre-tax benefits for transit/vanpool costs;
         (13)   Allocated space for bike share station/kiosk;
         (14)   Provide ongoing funding/sponsorship of bike share program/station;
         (15)   Provide transit, scooter, and bike share passes; or
         (16)   Provide website links to local transportation/commute programs that may include but are not limited to: Commuteride, City Go, alternative transportation programs on developer, property management, or employer websites.
      H.   Adjustments to Exceed Parking Maximums: Up to 10 percent of the parking maximum may be exceeded by the Planning Director through an administrative approval if the Planning Director determines that:
         (1)   The additional parking spaces are required to reduce adverse impacts to the surrounding neighborhood; and/or
         (2)   The additional parking is required due to unique characteristics of the use not generally shared by other uses in the same use category shown in Table 11-03.1 : Table of Allowed Uses.
   8.   Vehicle Parking Location and Design:
      A.   Location:
         (1)   Off-Site Locations Permitted: Parking required by Table 11-04.11 shall be provided on the same lot or combination of contiguous lots for which it provides required parking, except that in the R-3, Mixed-Use, Industrial, or Open Land zoning districts, parking may be located up to 600 feet from the lot containing the principal uses for which it provides parking.

11-04-010: ASSURED WATER SUPPLY:
   1.   Purpose: Boise City is committed to appropriate growth that does not exceed the supply of available water. The purpose of this Section is to confirm, prior to planning approval, the long-term adequacy of water supplies to serve the development or redevelopment of land. The City recognizes that water supply is regulated by several state agencies and does not intend this regulation to duplicate or conflict with such jurisdiction. Pursuant to the Local Land Use Planning Act (LLUPA), however, the City will consider the impact of development on water supplies and water quality. Assured water supply requirements are intended to provide protection and benefit to residents, the development community, designated water providers, and other regulatory agencies by ensuring that land development and growth aligns with long-term water supply needs. This Section is intended to supplement the roles and responsibilities of the State of Idaho's water supply regulators solely for planning and zoning purposes, to confirm that water resources will be available to serve continued growth in Boise.
   2.   Applicability:
      A.   Unless otherwise exempt pursuant to Section 11-04-010.3 below, beginning July 1, 2024, the following development shall demonstrate that it has an Assured Water Supply by providing an analysis that meets the requirements of 11-04-010.5 as part of the development application process:
         (1)   All proposed development on previously undeveloped lands; or
         (2)   All proposed redevelopment that:
            (a)   Includes the creation of five or more total dwelling units; or
            (b)   Is in a Groundwater Management District (GMD) defined by Idaho Statute 42-5224; Critical Groundwater Area (CGA) or Groundwater Management Area (GMA) defined by Idaho Statute 42-233A and 233B, respectively; or an Aquifer Recharge District (ARD) defined by Idaho Statute 42-4202.
      B.   These requirements apply whether or not the proposed development or redevelopment requires a Subdivision of Land.
   3.   Exemption: The Planning Director may exempt a project from the requirements of this Section if the applicant has submitted information demonstrating that, upon completion of the project and issuance of all required use and occupancy permits, the development or redevelopment will not increase total consumptive water use when compared to the use of the property at the time of application.
   4.   Designated Water Provider: Every provider of water for drinking or general domestic use as a public utility, with a service area within the City limits or the City Area of Impact and that intends to serve any proposed redevelopment or new development subject to the provisions of this Section, is required to be certified as a Designated Water Provider by demonstrating it has an Assured Water Supply, as defined in Subsection 5 and approved by the Planning Director or designee.
   5.   Elements of Demonstrating Assured Water Supply: To demonstrate a water supply is assured, the information provided shall meet the following criteria. A Designated Water Provider shall base its analysis of the criteria upon reasonable population projections within the existing certificated service area. An individual applicant shall base its analysis on the maximum permitted occupancy of the proposed development or redevelopment:
      A.   Physical and Legal Water Availability:
         (1)   An individual applicant shall demonstrate that it has sufficient physical and legal water availability by providing a copy of its water right permit or license issued by the Idaho Department of Water Resources or a decreed water right issued by a court of competent jurisdiction, with a permitted quantity in an amount sufficient to supply water to the maximum occupancy of the development. If the applicant does not have a water right permit, license, or decreed water right at the time of application, the applicant may submit, in the alternative, a hydrologic analysis demonstrating the physical availability of water supply for the demand of the development or redevelopment. In such case, any approval will be conditioned on the issuance of a water right permit or license.
         (2)   A Designated Water Provider shall demonstrate that it has sufficient physical and legal water availability by providing:
            (a)   A copy of the water right permit(s) or license(s) issued by the Idaho Department of Water Resources or water right(s) decree issued by a court of competent jurisdiction; and
            (b)   A hydrological analysis demonstrating the physical water supply, under such right(s), when used consistently over time, will be sufficient to meet the total forecasted demand at full build out within the existing certificated service area.
         (3)   A hydrological analysis shall include, at minimum, the following elements:
            (a)   A description of the study area;
            (b)   A description of all supply sources;
            (c)   Current annual demand, committed demand, and project future demand;
            (d)   Summary of depth to static water levels; and
            (e)   aquifer characterization and evaluation.
      B.   Continuous Water Availability:
         (1)   Demonstrate the redundancy in supply and delivery of water will be continuous and reliable under any reasonably foreseeable circumstance such as, but not limited to, peak demand in consideration of available supply and facilities, climate change, and priority administration of water rights for the 50 year period to service the:
            (a)   Proposed development for an individual applicant; or
         (b)   Forecasted total demand at full buildout within the existing certificated service area for a Designated Water Provider.
         (2)   For surface water, this may include consideration of historic diversions and volumes available compared to the maximum authorized diversions and volumes, as well as the timing of supply compared to timing of demand. For ground water, this may include consideration of historic well production compared to ground water elevations at the well(s), as well as historic recharge and recovery of aquifer storage and recharge well(s). The analysis of the reliability and continuity of water supply shall include long-term agreements, percentage of supply provided by each source, a description of the integration of all supply sources to meet demand under representative water-year types (wet, normal, dry, critically dry) and a drought plan.
      C.   Adequate Delivery and Quality: Approval of the development application will be conditioned on meeting applicable state requirements for adequate water delivery, storage, treatment works, and water quality. For purposes of certification, the Designated Water Provider shall provide its long-term capital improvement or facilities plan as part of this requirement.
      D.   Compliance with GMD, CGA, GMA, ARD Standards: If the application is located in a Groundwater Management District (GMD), Critical Groundwater Area (CGA), Groundwater Management Area (GMA), or Aquifer Recharge District (ARD), approval of the development application will be conditioned on meeting applicable state standards and requirements.
      E.   Standards and Guidelines: Established City standards and guidelines, as hereafter adopted or as amended, for implementing the Assured Water Supply provisions and conducting the Assured Water Supply analysis, are incorporated by reference and made a part of this Section and shall be enforced as requirements of this Code.
