A meeting was held 21JUL11 to go over the items submitted and discuss remaining items to be submitted. The subject property is currently located within a Special Flood Hazard Area (SFHA), Zone A as shown on the Flood Insurance Rate Map (FIRM), Community- Panel No. 04019C-2260L, effective date June 16, 2011.

The City of Tucson attorney's office and TDOT is reviewing the project, including the proposed access and maintenance easement and agreement which has not been submitted yet. Further comments are forthcoming due to comments from the City Attorney, TDOT, and FEMA/State floodplain representatives. It is understood by PDSD Engineering, that FEMA is expected to update the SFHA for the St Mary's campus from Zone A to X zone, once the Levee is constructed by Carondelet and certification is obtained. Engineering Division of Planning & Development Services Department has received and reviewed the resubmittal package and provides the following floodplain use permit comments per Floodplain, Stormwater, and Erosion Hazard Management Ordinance Sec.26-11.2.b and other sections of the Tucson Code and City of Tucson drainage standards.
