| Description | The dataset includes approximate flood-hazard boundary areas prepared by both detailed and approximate methods. Study limits were defined using the highlighted drainage-problem areas shown on the city's zoning base maps as a guide. Floodplain studies completed and sealed in 2007 and 2008 . Shape files created April 2011. Shape files exported from Autodesk Map 3D 2006 and projected using ArcMap 10.

| Use Constraints | The approximate flood-hazard areas were defined using the 1998 PAG DTM data and the HEC-RAS water-surface profile model. The hydrology was obtained from either the Tucson Stormwater Planner HEC-1 database or from individual calculations using the city's peak discharge procedure. The HEC-1 values were obtained from the Stormwater Planning Division. Standard hydrologic and hydraulic modeling accuracy limitations apply. For either procedure, if the non-co |
