Proposal to the City of Santa Ana for On -Call Environmental Services
<br />in-depth knowledge of appropriate and effective erosion and sediment control Best
<br />Management Practices (BMPs) and our team of project managers and environmental specialists
<br />regularly assist clients with the permitting and monitoring process.
<br />Traffic and Transportation Engineering Services
<br />KOA has extensive experience in traffic and transportation engineering and has provided traffic
<br />engineering services on many awarded winning projects throughout Southern California. Their
<br />staff of registered professional engineers and designers has extensive knowledge of standards
<br />and specifications such as the California Manual on Uniform Traffic Control Devices, Highway
<br />Design Manual, Highway Capacity, and Standard Plans for Public Works Construction, Caltrans
<br />Standard Plans and Specifications. They also have knowledge and experience in preparing
<br />Caltrans Encroachment permits, PEERs, and Fact sheets. KOA services include, but are not
<br />limited to traffic circulation study, vehicles miles traveled (VMT) analysis, transportation demand
<br />management plans, transit and access improvement plans, parking analysis and management
<br />measures, signal timing, engineering and traffic survey, collision data analysis, road safety
<br />audits and systemic safety analysis, signal and left -turn warrants, signing and striping design,
<br />bicycle facilities design, traffic signal, intelligent transportation systems (ITS), traffic
<br />management systems (TMS), street lighting, worksite traffic control plan, and traffic signal
<br />system inventory and master plan.
<br />Geotechnical
<br />Ninyo & Moore will provide geotechnical consulting services in preparation of environmental
<br />planning documents in accordance with the guidelines of the CEQA and NEPA. Ninyo &
<br />Moore's CEQA and NEPA-level evaluation will address the site geologic conditions, the
<br />proposed project's impacts on the geologic environment, the potential geologic and seismic
<br />hazards that may affect the project, and appropriate mitigation recommendations. Their
<br />approach to this evaluation generally entails review of geotechnical background materials,
<br />including topographic and geologic maps, published geotechnical literature, seismic data,
<br />groundwater data, and aerial photographs; geologic site reconnaissance; evaluation of the
<br />potential impacts that the project components may have on the existing geologic environment;
<br />assessment of the general geologic conditions and seismic hazards affecting the area, including
<br />surface fault rupture, ground shaking, liquefaction, landslides and mudflows, soil erosion,
<br />subsidence, settlement, and expansion or collapse of soils, and evaluation of their potential
<br />impacts on the project; compilation and geotechnical analysis of existing geotechnical data
<br />pertaining to the subsurface conditions; and preparation of a Geology and Soils technical report
<br />presenting findings, conclusions, and preliminary mitigation recommendations regarding the
<br />various geologic constraints for the project, as well as conclusions and recommendations
<br />relative to the geotechnical aspects of the project's conceptual design and construction.
<br />Environmental Site Assessments
<br />Ninyo & Moore will assist in conducting Phase I Environmental Site Assessments (ESAs) to
<br />evaluate if recognized environmental conditions (RECs) are present on project sites. RECs are
<br />basically the likely presence of hazardous substances or petroleum products in soil, soil vapor
<br />or groundwater at the property indicative of a release. The Phase I ESAs will be prepared in
<br />accordance with ASTM Phase I ESA Standard E1527-13. The Phase I ESAs are based on
<br />ECORP Consulting, Inc.
