Finding of No Significant Impact for Segment No. 7 of the Main Ditch Poinsett Watershed; Craighead and Poinsett Counties, Arkansas

Poinsett Watershed is a federally assisted action authorized under Pub. L. 83-566, Watershed Protection and Flood Prevention Act of 1954, as amended. The original Poinsett Watershed Work Plan was prepared in February 1968. The primary purpose of the plan is to provide flood reduction to the agricultural lands subject to flood damages. The plan was prepared by the local sponsoring organizations with technical assistance from the Natural Resources Conservation Service (NRCS). The Supplemental Watershed Plan No. 4 was prepared to add Segment No. 7 of the Main Ditch to the Plan. The Environmental Assessment (EA) was prepared to update and review items that are of concern with channel improvement for Segment No. 7 of the Main Ditch considering the present rules and regulations.

This particular action involves only the channel improvement of Segment No. 7 of the Poinsett Watershed. Federal assistance will be provided under authority of the Pub. L. 83-566, Watershed Protection and Flood Prevention Act of 1954, as amended. The EA was conducted in consultation with local, State, and Federal agencies as well as with interested organizations and individuals.

Data developed during the assessment are available for public review at the following location: U.S. Department of Agriculture, Natural Resources Conservation Service, Room 3416, Federal Building, 700 West Capitol Avenue, Little Rock, Arkansas 72201-3225.

The drainage area at the downstream end of the Segment No. 7 is 20.6 square miles. The project area is located in northeastern Arkansas in Craighead and Poinsett Counties. The southern limit of the city of Jonesboro is located in the northern most part of the watershed. The watershed land use of Segment No. 7 is about 30 percent (%) urban, 40% cropland, and 30% pasture, range, and woods.

Local Sponsoring organizations are Poinsett Watershed Improvement District, Craighead County Conservation District, and Poinsett County Conservation District.

Alternatives

Alternative 1 is the No Action or Future Without Project. This alternative consists of maintaining the existing channel capacity of Segment No. 7 of the Main Ditch. No Federal funds would be spent on Segment No. 7. Flood damages to agricultural areas, infrastructure, and residential area in the floodplain would continue at the present level.

Alternative 2 is the Channel Improvement of Segment No. 7. This alternative consists of improving the existing channel from station 1328+00 to 1542+60, two rock chutes to stabilize grade, and 33 grade stabilization structures to drop water from the field or drains into the ditch improvement. This alternative will meet the need and purpose of the project to provide flood protection benefits to the agricultural land along Segment No. 7, infrastructure in the project area, and residences in the southern part of Jonesboro.

Recommended Action

Alternative 2 is the recommended alternative and consists of channel improvement of Segment No. 7 of the Main Ditch to provide for flood prevention benefits. This alternative provides the most net benefits and is the National Economic Development (NED) Plan.

Effects of Recommended Action

Benefits of Recommended Action

The estimated total average annual monetary benefits will be $94,220. The average annual cost is $78,000, resulting in a benefit to cost ratio of 1.2 to 1.0.

Impacts of Recommended Action

Floodwater Impact

The existing channel has inadequate capacity to protect cropland and other agricultural lands from flooding by moving floodwaters from Jonesboro through the agricultural areas. The average annual area flooded within Segment No. 7 evaluation reach is approximately 1770 acres. Channel improvement of Segment No. 7 would reduce flood damages to agricultural lands, infrastructure, and other private lands. The average annual area flooded would be reduced by 1,470 acres.

Archeological and Historical Impact

Requirements of Section 106 of the National Historic Preservation Act of 1966 as amended were fully implemented. Planning activities for the protection and preservation of historic properties have been conducted in compliance with Section 106 and Section 110 (f) and (k) of the National Historic Preservation Act. Processes consistent with the Advisory Council on Historic Preservation regulations (36 CFR 800) have been followed by NRCS. No known cultural resources were identified. NRCS will take action to protect and/or recover any historic properties discovered during construction.

Fish and Wildlife Resources Impact

The land use on both sides of the ditch is open cropland with the exception of two small wooded areas. The open cropland affords food for seed-eating birds and provides some ground cover. Water within the ditch is very shallow and unshaded. Some species of fish such as sunfish, carp, buffalo, and catfish may use the ditch at various times. However, fishery habitats are very low quality and are of very little value as a fishery resource.

The channel improvement will have minor short-term impact on the existing fishery habitats. Reduction in flooding depth and duration in the floodplain will improve the upland wildlife habitats on agricultural land.

Threatened and Endangered Species Impact

The endangered fat pocketbook Potamilus copax (mussel) occurs within Craighead County, Arkansas. However, the U.S. Fish and Wildlife Service has determined that this endangered species is not located within the project area (USFWS, 2004). The project will have no adverse impacts to any threatened and endangered species.

Prime Farmland

Presently, there are 4,005 acres of prime farmland in the project area. Prime farmland will be impacted by reduced frequency and depth of flooding on 1,209 acres. Enlargement of the planned channel will result in a loss of 78 acres of prime farmland adjacent to the existing ditch. Overall there will be a positive impact on prime farmland due to a reduction in flooding.

Wetlands Impact

The land use on both sides of the ditch is open cropland with the exception of two small wooded areas. The wooded area located at approximately from channel station 1369+00 to station 1381+00 has some minor wetlands. These are located greater than 90 feet from the centerline of the existing channel.

Construction methods will be used to avoid any adverse impacts. The channel will be constructed from both sides with spoil placed approximately equally on both sides of the ditch except at the location from channel station 1369+00 to station 1381+00. At that location construction methods will be used to limit fill on the side where the wooded area is located. Constructed channel dimensions on the wooded area side will not extend past 90 feet with limited fill on that side to maintain existing wetlands and spoil elevations. Using these construction methods, there will be no adverse impacts to the minor wetlands within the wooded area.

Conclusion

The purpose of the improvement to Segment No. 7 of the Main Ditch is to provide flood prevention benefits to the agricultural lands, infrastructure, and residential area along Segment No. 7. The Environmental Assessment summarized above indicates that this Federal action will not cause significant local, regional, or national impacts on the environment. I find that neither the proposed action nor any of the alternatives is a major Federal action significantly affecting the quality of the human environment. Therefore, based on above findings, I have determined that an Environmental Impact Statement for Segment No. 7 of the Main Ditch, Poinsett Watershed is not required.
