RFP #21-017: On -Call Environmental Review Services for the CHAMBERS Housing Division GROUP City of Santa Ana Community Development Agency • Evaluate and quantify local criteria pollutant emissions associated with construction and operational activities for the proposed project utilizing SCAQMD's Look -Up Tables. • Provide a qualitative odor analysis from the construction and on -going operations of the Proposed Project. • Prepare an air quality and GHG emissions report that documents the results of the previous work tasks. Noise Impact Analysis Vista Environmental will provide the following tasks: • Identify transportation -related noise sources such as major roadways, railroads, and aircraft noise (if any), and stationary (non -transportation related) noise impacts from adjacent land uses to the project study area. • Identify the applicable HUD noise regulations that are detailed in 24 CFR Part 51 — Environmental Criteria and Standards • Evaluatethe existingnoise environmentand obtain either 15-minute or24-hour noise measurements inthevicinity of the Project. • Utilizethe Federal Highway Administration's Roadway Construction Noise Model (RCNM)to analyze potential noise impacts associated with construction activities and identify measures to minimize the noise impacts to the nearby sensitive receptors. • Provide a description of the nearby roadways that details how all of the roadways within 1,000 feet of the project site are either local or collector roads and do not qualify as either a major highways or busy roads. Also, detail the nearest major roadway to the project site is Interstate 5 that is over 1,000 feet from the project site and therefore outside of the quantitative noise analysis range. • Compare the calculated noise levels (limited to rail noise) to the HUD exterior and interior noise standards. If an exceedance of either the exterior or interior noise standard is found at the project site, provide mitigation to reduce the noise impacts to within the HUD noise standards. • Analyze potential vibration impacts associated with construction and operational activities through application of the methodology used in the Transportation- and Construction -Induced Vibration Guidance Manual (Vibration Guidance Manual), prepared for Caltrans. • Prepare a noise impact report that documents the results of the previous work tasks. Phase I Environmental Site Assessment (Converse) Converse will generally follow the standard practices of the American Society for Testing Materials (ASTM) Phase I Environmental Site Assessment Process (Standard: E1527-13) and HUD Guidelines. The ASTM Standard E1527-13 is intended to satisfy one of the requirements to qualify for the Landowner Liability Protections (LLP) within the scope of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), that is, the practices that constitute all appropriate inquiry (AAI, 40 CFR Part 312) into the previous ownership and uses of the property consistent with good commercial or customary practice. The following Scope of Services is proposed: 1. Review of regulatory agency records, aerial photographs, fire insurance maps, city directories, building permits, USGS topographical maps and other non-standard historical sources. 2. Visual survey of property and adjacent sites for indications of potential for contamination or contamination generators.. 3. A reasonable attempt will be made to interview the owner(s), site manager(s), and major occupant(s), and to contact State or local government officials. 4. Prepare report signed by an Environmental Professional for electronic submittal. Phase II Environmental Site Assessment and Soil Testing (Converse) The objectives of a Phase II investigation are to: evaluate the likelihood that potentially hazardous materials are present at the site; assess the nature and concentrations of the chemical compounds; assess the vertical and horizontal extent of impacted soil through testing, as well as the impact to groundwater; determine if the subject property will require some form of remediation and evaluate the most feasible remedial alternative to remediate the site. The scope of services for a Phase II investigation is typically based on the results of a Phase I ESA and/or other Phase II investigations. Est w t�` 1919 www.chambers910upinacom
