EMERGENCY WATERSHED PRllT£CTION CABARRUS COUNTY, NORTH CAROLINA ' NONEXIGENCYSlTUATION REPORT Total estimate of funds needed for SCS assistance are estimated to be: $16,000.00 for financial assistance and $3,000.00 for technical assistance. No funds are anticipated for FS. A storm event occurred on July 15, ]984 during the time 1800-2100 hours EDT. Some 5.4 inches of rainfall were recorded during this 3-hour period. Intense rainfall resulted in runoff quantities exceeding capacities of stream channels and in very high velocity of stream runoff during cresting period prior to exceeding channel capacities. Funding is requested for nonexigency work on July 19, 1984. Members of the investigating team were: T. H. Wetmore, Jr., Area Conservationist; Vernon H. Jones, Area Engineer; H. D. Price, District Conservationist; and B. W.M~ll, District Technician. A detailed i~vestiga~iun was conducted in the area affected by the event on July 17,'1984. during the hours 0930-1600. Major area affected in Cabarrus County, North Carolina was in the central portion of the county primarily between just east of Concord~ NC eastward to just southeast of Mt. ~leasant, NC, Impacts of the storm event were: (1) dislodgement of standing trees from stream banks, 12) undermining o~ existing trees on stream banks: (3) accumulation of dislodged trees in stream channel creating blocks which diverted stream flow into adjacent cropland, pastureland, and wooded areas; (4) accumulation of dislodged trees and woody debris at public road culverts causing flows to overtop roadways, cutting bardsurface road materials by undermining, damages to bridges and creating potential threat to human life; (5) restricted carrying capacity of stream channels resulting in agricultural crops being inundated; (6} diverted stream flows from ~ormal stream channels cutting/scouring cropland adjacent to stream and velocity damages to agricultural crops such as cern; (7) channel blockages creating swirl action to cause streambank erosion; (8) damages to livestock fences by dislodged trees and debris; (gl silt accumulation on agricultural crops. Major area affected is predominantely rural, agricultural with some residents working in towns nearby, lhis is the major agricultural section of Cabarrus County. Attached. map shows major area Impac'~ed by s~orm event. Red areas show approximate locations of potential damages ~hat would be prevented by emergency treatment. These are secondary roads, cropland areas and generally all areas adjacent to streams. Streams, as indicated, are to receive emergency treatment to reduce potential damages. Estimated treatment is to remove stream blocks of fallen trees which are lodged in the channel and to remove trees on immediate stream banks which have been undermined and are leaning (greater than 30° off vertical) over bhe stream channel. An estimated lO.Omiles of stream channel needs blocks removed. These blocks are intermittently located along the channels. Blocks consist of trees ra~ging from 8-14 inches DBH and portions of trees such as large limbs, stumps, etc.
