Attachment A -Mitigation, Monitoring & Enforcement Program Attachment A Mitigation, Monitoring, and Enforcement Program. The new courthouse would be constructed according to the Uniform Building Code seismic zone 3 design specifications, with consideration of the Oregon Structural Specialty Code (1997). No unusual soil or foundation conditions are likely to occur on any of the alternative sites. Nonetheless, a geotechnical study would be conducted as part of the design process. Erosion and sedimentation controls may be implemented during construction to prevent water quality impacts resulting from demolition and construction activities. In order to avoid impacts on fisheries, best management practices may be implemented to control. stormwater runoff during construction. Landscaping would be designed to include open-space areas planted with native species that attract urban wildlife. The GSA may continue consultation with the Oregon State Historic Preservation Office to determine the measures required to mitigate the potential impacts on historic resources. A memorandum of agreement between GSA and the state to outline mitigation measures maybe developed to address impacts. The design of the courthouse may consider using low-reflectance materials for the building cladding and landscaping to soften the exterior lighting. The facility may include directional and shielded exterior lighting fixtures to minimise offsite aesthetic impacts. Landscaping should be designed in a manner that establishes a connection to the surrounding area and is consistent with safety and security requirements of the facility. In accordance with city regulations, construction activities may be limited to daytime hours (7 a.m. to 6 p.rn.) in order to minimize noise impacts during construction, if such limitation does not adversely affect the interests of the construction project. A formalized plan for removal, treatment, and management of contaminated soil and ground water would be prepared prior to construction. Long-term maintenance and operation of the federal facility would implement standard operating procedures to address management of hazardous materials. These procedures involve development of a programmatic health and safety plan; worker training; materials use planning; and a tracking, documentation, and waste management plan. In order to reduce the demand for parking and mitigate the expected shortfall, the GSA may advise facility tenants that they should comply with applicable transportation regulations. Utilities displaced during construction may be relocated in order to mitigate any potential long-term impacts. Courthouse facility utilities may be designed to conserve energy and water. In addition, GSA may meet with the city fire and police departments during design and construction to discuss their concerns. t New Federal Courthouse 1 of 1 Record Of Decision
