For the purpose of this division, the following words, phrases and terms shall have these meanings:
CDC MODEL. The official CDC HEC-RAS computer model of the Upper Trinity River study area. The CDC Model includes constructed projects and several projects that are permitted but no constructed.
CDC REGULATORY ZONE. The area where the CDC Process and requirements apply. This area is FEMA 100-year floodplain (also known as the special flood hazard area) minus areas of Specific Prior Development.
CORRIDOR DEVELOPMENT CERTIFICATE (CDC). Permission for development activity within the Regulatory Zone of the Trinity River Corridor. The CDC is issued by the city as part of the floodplain permitting process prior to development.
CORRIDOR DEVELOPMENT CERTIFICATE MANUAL (CDC MANUAL). The document published by NCTCOG that provides information on the CDC process, including the CDC application.
DEVELOPMENT. Any human-made change to improved or unimproved real estate, including but not limited to, the construction or alteration of buildings or other structures, mining, dredging, filling, grading, clearing, paving, excavation, drilling operations or storage of equipment or materials. This also includes any levee or other improvement defined by the Texas Commission on Environmental Quality (TCEQ).
NORTH CENTRAL TEXAS COUNCIL OF GOVERNMENTS (NCTCOG). Voluntary association of, by and for local governments, established to assist local governments in planning for common needs, cooperating for mutual benefit, and coordinating for sound regional development.
STANDARD PROJECT FLOOD (SPF). The flood that may be expected from the most severe combination of meteorological and hydrologic conditions that are considered to be reasonably characteristic of the geographical region involved, excluding extremely rare combinations. In practical terms, a SPF usually has a 0.30 to 0.08 percent probability of being equaled or exceeded in any given year, and is usually between 40 and 60 percent of the Probably Maximum Flood (PMF). The SPF represents a "standard" against which the degree of protection selected for a project may be judged and compared with protection provided for similar projects in other localities. In general terms, the SPF for the Trinity River Corridor is commonly equated to an 800-year storm frequency.
TRINITY RIVER CORRIDOR. Within the City of Fort Worth, the Trinity River Corridor is defined as the bed and banks of the Trinity River from the dams of Lake Worth and Benbrook Lake, downstream to the eastern corporate limit, and all of the adjacent land area and all watercourses within the boundaries of the river floodplain within the Fort Worth city limits.
