REMEDIAL MEASURES

· South of the airport, focus on voluntary relocation:

1. complete current program

2. incorporate newly eligible (DNL 65+) buyouts

3. promote compatible redevelopment via Renaissance Zone· North of the airport, focus on remediation:

1. residential soundproofing in projected DNL 65

2. institutional soundproofing in projected DNL 65

3. residential sales assistance, for those declining soundproofing

4. residential and institutional soundproofing in DNL 60, where projected exposure will increase more than 3 dB - subject to Federal eligibility and available funding

· Lateral to the airport, establish noise barriers, to ccunter ground noise:

1. northern Louisville Avenue area, opposite Beechmont neighborhood

2. southern I-65 area, opposite Preston Park neighborhood

COMPENSATORY MEASURES

· Obtain avigation easements on residential properties – primarily in conjunction with other associated measures, like insulation, sales assistance or overlay zoning

PREVENTIVE MEASURES

· Comprehensive planning: refine treatment of airport compatibility in form district designations and descriptions in Cornerstone 2020 plan

· Land use zoning: pursue compatible-use zoning policies, and implement zoning actions, consistent with airport noise contours

· Overlay zoning: to the extent existing zoning classifications need further delineation, apply overlays to identify noise impacts and promote non-sensitive development

· Subdivision regulations: incorporate in Land Development Code provisions for disclosure and mitigation in new development within noise-impacted areas

· Building code: promote augmentation of state code to prescribe noise mitigation standards in construction in noise-impacted areas

· Disclosure ordinances: consider local ordinances or other measures to require noise exposure information be provided to prospective property buyers

MANAGEMENT MEASURES

· Use the airport noise office as a central collection and distribution point for mitigation policy and status information

· Use the Relocation Working Group to provide lay oversight and advocacy of the mitigation program

· Augment the Web site and information centers to incorporate and maintain mitigation policy and program information

· Reinforce communications and liaison links with staff, local government agencies, brokers and developers, media, and public

EVALUATIVE MEASURES

· Collect and assess statistics on mitigation program execution

· Develop and track legislative initiatives to implement land use measures

· Process noise complaints and provide feedback on the mitigation program

· Document and evaluate emerging technologies and measures for potential future application

SENSITIVE FACILITY #1: UofL

Targeted Measures:

· offset approach & departure path

· reverse flow during arrival-dominated period

· flight track management by capability

· extended flight corridors, waypoints

· supplemental metrics: peak levels, time above

· insulation assessment

· aggressive oversight, evaluation

Key Issues:

· minimize classroom, research disruption

· avoid undue impact on campus residents

· respect adjoining neighborhoods

CONTINUING CONCERNS

· “lessons learned” for other sensitive facilities

· details of implementation plan

· careful oversight and refinement

· documentation and ongoing communication
