Unified Land Development Code - Town of Gilbert

GILBERT UNIFIED LAND DEVELOPMENT CODE
The Town may require a neighborhood design analysis to be updated if construction of the
project has not occurred within five years from the date of formal submittal to the town.
E. Development Standards within the Santan Freeway Corridor Overlay District
All development of noise sensitive uses within the Santan Freeway Corridor Overlay District shall
comply with the following development standards.
1. The height of buildings on lots completely or partially located within 150 feet adjacent to
the exterior edge of the right-of-way boundary on each side of the Santan Freeway
alignment shall be limited to a single story. The Council may approve a greater number
of stories for noise sensitive uses other than single family residential if the Neighborhood
Environmental Design Analysis demonstrates that site design elements of the project
targeted at reducing noise impacts will achieve the same or greater effect on interior
noise levels as the height restriction.
2. Developers shall provide noise barriers to mitigate the negative impacts of freeway
noise. The height and design of the noise barriers shall achieve an exterior noise level
reduction of at least 5 dBA Leq (h) and meet the noise mitigation levels prescribed by the
Arizona Department of Transportation's noise policy. The height and design of noise
barriers shall be supported by an engineering or noise study and comply with structural
standards adopted by the Arizona Department of Transportation. Prior to recordation of
the final plat, the developer shall submit a statement signed by a licensed engineer or
qualified professional transportation noise analyst certifying that the noise barriers will
achieve the required noise attenuation. Design of the noise barriers shall include
compatible design elements approved by the town.
3. Developers have the option to place on deposit with the town a sum equivalent to the
cost of the noise mitigation barriers as determined by the town. This deposit shall be
made prior to recordation of the final plat.
4. Developers may contract for additional landscaping to be provided at the developers'
expense within or adjacent to the freeway right-of-way.
5. Barriers required pursuant to this section are exempt from the height limitations
prescribed by Article 11, Section 2.4 of the Gilbert Unified Land Development Code.
6. Building construction shall achieve a maximum interior noise level of 45 dBA Ldn and
meet the minimum standards for interior noise levels prescribed by the Federal
Department of Housing and Urban Development. Prior to consideration by the Design
Review Board, the developer shall submit a signed and sealed letter from a licensed
architect, engineer or qualified transportation noise analyst certifying that construction
materials, methods and design employed achieve the required noise attenuation. A copy
of the certification shall also be submitted with the application for a building permit and
shall be attested to on the plans.
