CHESTNUT CREEK, VA. WAR DEPARTMENT, OFFICE OF THE CHIEF OF ENGINEERS, The CHAIRMAN, COMMITTEE ON FLOOD CONTROL, House of Representatives, United States, Washington, D. C. MY DEAR MR. CHAIRMAN: 1. The Committee on Flood Control of the House of Representaives, by resolution adopted November 19, 1940, requested the Board of Engineers for Rivers and Harbors to review the report on the Kanawha River Basin, submitted in House Document No. 91, Seventy-fourth Congress, first session, with a view to determining if mprovement of Chestnut Creek, Va., with a view to flood control, is dvisable at this time. I enclose the report of the Board in response hereto. 2. After full consideration of the reports secured from the district and division engineers, the Board recommends the construction of a ocal protection project at Galax, Va., on Chestnut Creek, consisting of levee construction, wall construction, channel improvement, and ailroad-bridge reconstruction, generally in accordance with the plans of the district engineer but with the height of levees up to 3 feet higher than proposed, all at an estimated first cost to the United States of $276,125, provided local interests give assurances satisfactory to the Secretary of War that they will: (a) Provide without cost to the United States all lands, easements, and rights-of-way necessary for construction of the project; (b) make all necessary changes in highways, highway bridges, and drainage facilities; (c) hold and save the United States free from damages due to the construction works; (d) maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of War. 3. After due consideration of these reports, I concur in the views and recommendations of the Board. Very truly yours, E. REYBOLD, 1 REPORT OF THE BOARD OF ENGINEERS FOR RIVERS AND HARBORS WAR DEPARTMENT, a 80 THE BOARD OF ENGINEERS FOR RIVERS AND HARBORS, am Subject: Chestnut Creek, Va. 1. This report is in response to the following resolution adopted en November 19, 1940: th Resolved by the Committee on Flood Control of the House of Representases, or dr he to on, a ete I le con ecomm pst to 2. Kanawha River is formed by the confluence of the New and om an he pods 15.400 ahane jecessar nited nd (c) be flood at pro A main od-cont rovide fo 3. Floods occur annually in Chesnut Creek Basin usually as a rovement of of maxin gion. omplete oposed for st t onstruct sed by at the Chestnut in reg neer, at 96894 widening and deepening of the creek channel through the town, and the possible construction of supplementary levees. The construction of a flood-control reservoir at one of two possible sites above the town is advocated as an alternative project. Local interests agree to furnish all required local cooperation, hold the United States free from damages, and operate and maintain the works after completion. 4. The district engineer has investigated various plans of improvement for protection of the flood-plain area along Chestnut Creek. He finds that the most suitable one is the construction of levees along both banks of Chestnut Creek and the alining, deepening, and enlarging of the present channel through the town of Galax, Va., all as shown on the accompanying map. The first cost of this improvement is estimated at $322,000, of which $167,875 is for the levee, channel, and wall work, $72,750 for the reconstruction of the railroad bridge, $3,750 for highway and highway bridge changes, $35,625 for drainage facilities, and $42,000 for lands and rights-of-way. The total annual carrying charges, including maintenance and operation, are estimated at $13,060. The improvement will provide complete protection to the town of Galax and based on possible future floods and future valley occupancy will produce annual benefits of $15,400, of which $14,400 is flood damage prevented and $1,000, enhancement in land value. The ratio of cost to benefits is 1 to 1.2. He concludes that the improvement is economically justified and he recommends it subject to the conditions that the town give assurances satisfactory to the Secretary of War that it will: (a) Provide without cost to the United States all lands, easements and rights-of-way necessary for the construction of the project; (b) hold and save the United States free from damages due to the construction works; and (c) maintain and operate all the works after completion, including the flood-carrying capacity of Chestnut Creek downstream from Galax from any future encroachments or obstructions which might reduce the protection afforded by the project, in accordance with regulations prescribed by the Secretary of War. 5. The division engineer is not convinced that the height of levees proposed by the district engineer is entirely adequate, based on records of maximum discharges from the stream basins of similar size in the region. He believes that prior to construction of the project, more complete stream flow data will be available. He therefore concludes that provision should be made to permit a selection of a height of levee at the time of construction as much as 3 feet higher than that proposed by the district engineer, if found desirable. The additional cost for the increased height of levees is estimated at $38,000. This construction will provide for a design flood one-third larger than proposed by the district engineer. The division engineer further believes that the requirement for protecting the flood-carrying capacity of Chestnut Creek downstream from Galax can be adequately provided for in regulations prescribed by the Secretary of War for operation and maintenance of the project. He recommends that the existing flood-control project for the Kanawha River Basin be modified to provide for construction of a local protection project at Galax, Va., comprising levee construction, wall construction, and channel improvement in general accordance with the plans of the district engineer, at an estimated first cost of $360,000, of which $44,500 must be borne by local interests in furnishing lands and rights-of-way. 96894-44 VIEWS AND RECOMMENDATIONS OF THE BOARD OF ENGINEERS FOR c tion i inal 6. The Board has carefully considered the reports of the division and district engineers. Based on the stream flow records now available, the improvement proposed by the district engineer will provide complete flood protection for the town of Galax, Va., and will produce sufficient benefits to justify participation by the United States. The Board, however, concurs with the division engineer in the view that provision should be made so as to permit a selection of height of tip levee at the time of construction as much as 3 feet higher than that econ proposed by the district engineer. Due to the local nature of the je benefits, the Board believes it equitable that local interests provide te all drainage facilities and relocate the highway, and highway bridge, tion o in addition to furnishing the lands and rights-of-way. Accordingy, the the Board recommends the construction of a local protection project at Galax, Va., on Chestnut Creek, consisting of levee constructam, plans wall construction, channel improvement, and railroad bridge reon- $250 struction, generally in accordance with the plans of the district angineer but with the height of levees up to 3 feet higher than proposed, all at an estimated first cost to the United States of $276,125, provided local interests give assurances satisfactory to the Secretary of: War that they will: (a) Provide without cost to the United States all lands, easements, and rights-of-way necessary for construction of the project; (b) make all necessary changes in highways, highway bridges, and drainage facilities; (c) hold and save the United States free from damages due to the construction works; (d) maintain and operate al the works after completion in accordance with regulations prescribed by the Secretary of War. cordit Subje For the Board: JOHN J.

A Kanaw Senior Member. plance House follows Resol States, T 3 of the SYLLABUS Number if impro Chestnut Creek is a comparatively small headwater tributary of New River, major tributary of Kanawha River. The occurrence of major floods, with extremely high unit peak discharges, at relatively frequent intervals, results in flooding of bottom lands along the stream to varying depths, but because of valley occupancy the resulting flood problem is not especially serious except at the town of Galax, Va. At Galax the location of important industries and a residential section on the flood plain creates a flood problem unusually severe for the size of the town. to revien Decemb at nomi Investigations of possible measures for flood control on Chestnut Creek have The town of Galax is preparing to submit an application to the Work Projects advisable 2.Or and Ha 3. Re ing the House 1 with mo Harbor of the F presently required sponsor's share of the total project costs. In view of the economic justification of the project, it appears that its construction by the War Department is advisable if the town fails to sponsor construction by the Work Projects Administration. However, because of the local nature of the benefits it appears that local interests should be required to bear the costs of rights-of-way and damages and to agree to operate and maintain the project after its completion. Preliminary assurances have been given that such local cooperation will be furnished. In view of the foregoing, the report recommends that construction of the proposed Galax, Va., local protection project be undertaken by the War Department, if local interests fail in their attempt to secure a Work Projects Administration project, at the earliest date that current national defense activities and national economic conditions permit; that no money be expended on construction of the project by the War Department until the town of Galax has given assurances satisfactory to the Secretary of War that it will (a) provide without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the project, (b) hold and save the United States free from damages due to the construction works, and (c) maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of War; that an initial allotment of $25,000 for surveys, design, and the preparation of contract plans and specifications be made at this time; and that a single allotment of $255,000 for completion of construction be made at such time as national economic conditions will permit. WAR DEPARTMENT, Subject: Review of Report on the Kanawha River Basin to determine if improvement of Chestnut Creek, Va., for flood control is advisable at this time.
