Townhouses-SY000824 (2)CDC Information
Oeneral
The project area consists of a 10-acre tract adjacent to MacArthur Road and south of Sandy Lake Road.
This tract is shown on the drawing in this appendix. The project consists of fill in the floodplain with
compensating excavation that results in no increase in flood levels and no decrease in 100 year flood
storage.
Hydrologic and Hydraulic Information
The ten-acre tract is affected by the flood elevations fi.om the Elm Fork of the Trinity River. However,
these elevations are blocked from the actual flow of the river. The area is in an ineffective flow regime and
thus has no impact on flood elevations as long as storage levels are not reduced. This means that filling the
tracts has no impact on the flood elevations.
Storage Determinations
It is important to offset any lost storage created by filling the tract. This is accomplished by excavating a
portion of the adjacent tract as shown on the attached drawing. In order to determine the storage on the
property before and after the proposed project a computer model was created by describing cross sections
through the area. The results of this analysis are included in this appendix.
Results
The project site is in an area that receives floodwaters fi.om the Elm Fork of the Trinity River, but is
isolated from the actual flow of the river. Because of this the area can be filled w~thout impact to the flood
elevations of the river. This report has identified storage mitigation so that there is no net decrease in flood
storage.
CDC Forms
All required forms in support ora CDC approval are included in this appendix.
- - Standard CDC Form Instructions
September 1998
This application should be completed according to the guidelines set forth in the 2nd Edition
the CDC Manual.
To initiate the Corridor Development Certificate (CDC) permit process, the developer
should first contact the local government (City) for a pre-permit conference. The
CDC/Floodplain Administrator of that local government determines whether the project
lies within or partially within the Regulatory Zone. If the project lies completely outside
the Regulatory Zone, the CDC/Floodplain Administrator is not required to take any
further action beyond making this determination; no forms are required to be submitted
and the CDC process ends at this point.
If the project lies within or partially within the Regulatory Zone and there is a possibility that a
CDC permit might be granted, the CDC Process must be followed. The Applicant should fill out
Parts 1 and 2 of the Standard CDC Form and submit it to the CDC Floodplain Administrator
-- unless the Applicant is seeking an exemption, in which case the Applicant must only complete
Part 1. If the CDC/Floodplain Administrator decides at any time to deny a CDC permit, the CDC
Process can be terminated.
Information provided by the Applicant herein will be used by the City/County to evaluate this
Trinity, River Corridor Development Certificate (CDC). This application is public information
- and will be used by other relevant floodplain regulatory authorities, i.e., U.S. Army Corps of
Engineers (USACE), Federal Emergency Management Agency (FEMA), and the Texas Natural
Resource Conservation Cormnission (TNRCC). These and other regulato~ agencies may requite
additional information.
If an Intent to Process (1TP) is granted, the Standard Form shall be distributed to the following
agencies:
· USACE;
· FE/VlA;
· TNRCC;
· the North Central Texas Council of Governments (NCTCOG);
_ · the cities of Arlington, Carrollton, Coppell, Dallas, Farmers Branch, Fort Worth, Grand
Prairie, Irving. and Lewisville;
· the counties of Dallas, Denton and Tan'ant;
_ · the Tarrant Regional Water District; and the Trinity River Authority.

appropriately.
- Hvdrologic and Hydraulic Data
Design discharges for the 100-year and Standard Project Flood storm events shall be based on
urbanization consistent with a "Future Conditions with CDC" Scenario or on supplemental data
provided by the USACE, whichever discharge is larger. (See Table 1 in Appendix B.) The
Applicant should identify these design discharges, including source and date, in the "100 Year
Flood Event" and "SPF Flood Event" tables in Part 2 #3.
Hydraulic calculations shall be continued for a distance great enough upstream and downstream
of the project to verify that water surface elevations are not raised by the proposed hydraulic
modifications (spaces are provided in the "100 Year Flood Event" and "SPF Flood Event" tables
in Part 2 #3 to list water surface elevations for a number of points upstream and downstream).
Elevation data should be computed considering full cross-section widths across the river or
creek.
Storage data for pre-project and with-project conditions (Part 2 #3) shall be developed within the
project borders alone and considering full cross-section widths across the river or creek. Storage
change is to be considered "on-site" (i.e., within upstream and downstream limits of the
discharge reach.) Compensating valley storage for a proposed activity can also be provided at
another site if the USACE recognizes and approves the "off-site" valley storage. In addition, if
any valley storage is lost elsewhere due to the project, storage change shall be addressed on a full
cross-section width basis, with change based on the original "on-site" storage.
