Flood Boundaries
收藏资源简介：
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.Maintenance and frequency to be determined by City of Tucson, Planning and Development ServicesReplace feature class "dsdFHZStudy2007CrossSections"See feature class "cotFloodHazards" 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.
