4311 Avenue Cultural Resources Assessment Survey <br />October 6, 2025 <br />to reconstruct past land use and assess the potential for archaeological sites and historic <br />resource within the project areas. Precolumbian period and historic period contexts will <br />also be reviewed and developed to provide a framework within which the archaeological <br />and historical records can be understood. A summary of the project area's archaeological <br />and historic contexts and pertinent environmental features will be prepared from the <br />results of the archival research. This information will inform the survey strategy and <br />provide the context in which the significance of any resources identified during the project <br />can be evaluated. <br />Cultural Resource Assessment Survey <br />The CRAS will include a survey to identify both archaeological sites and historic resources. <br />Based on the proposed improvements, the area of potential effect (APE) will be narrowly <br />defined and only resources directly within the APE will be documented. <br />Archaeological Survey <br />The archaeological survey will include a reconnaissance level survey to document existing <br />conditions and determine where archaeological subsurface testing is feasible. Any area <br />where archaeological subsurface testing is possible will be marked and coordination with the <br />Sunshine 811 Call Center will be conducted to locate any underground utilities. Areas where <br />excavation is not possible will be documented with field notes and photographs. <br />Subsurface tests will be .5 m (20 inches) in diameter and dug to a minimum depth, subsurface <br />conditions permitting, of one meter (3.3 feet). All excavated soils will be sifted through 6.4 <br />mm ('/4 inch) metal hardware cloth screen suspended from portable wooden frames. Any <br />cultural materials recovered will be stored in plastic bags with all provenience data recorded. <br />Field notes on each test performed will be recorded, and the location of all tests will be clearly <br />marked on aerial photographs of the project area. A Florida Master Site File form will be <br />completed for any archaeological site identified during the survey. <br />Historic Resources Survey <br />A historic structures survey will be conducted to ensure that historic resources constructed <br />in 1977 or earlier are identified and documented. Resources directly within the APE will <br />be identified and documented on Florida Master Site File forms (FMSF). Photographs will <br />be taken and a log kept recording the resource's physical location and compass direction of <br />each photograph. Each resource's individual significance will then be evaluated for its <br />potential eligibility for listing in the National Register of Historic Places (National Register). <br />Historic physical integrity will be determined from site observations, field data, and <br />photographic documentation. <br />Documentation and Report Preparation <br />A draft report presenting the methods, findings, evaluations, and recommendations of the <br />cultural resource assessment will be prepared and submitted to Kimley-Horn for review and <br />comment. The draft report will be submitted electronically. Any comments will be <br />incorporated into the final report, which will also be submitted to Kimley-Horn electronically. <br />If requested, Janus Research will prepare and submit the final report and associated <br />documentation to the Florida State Historic Preservation Officer (SHPO)/FDHR. <br />Janus Research Page 2 <br />
