The project site is 1ocated near the Town of Caibondale within Section 32, Township 7 SouLh, Range 87 West, Garfield County, Colorado. The Chief of Engineers has issued Nationwide General permit number 13 which authorizes the discharge of dredged or fiII material in waters of the United Stat.es for bank stabilization. We have determined that your project will not affect t.hreatened or endangered specles protected by the Endangered Species Act.

It is proposed to armor 150 feet of bank on the Roaring Fork River at the rate of 1 .5 cubic yards per foot of bank for a total of 225 cubic yards of rock 2-5 feet in diameter. The project is located in Garfield County in Section 32, Township 7 South, Range 87 west of the 6ft P.M. The applicant and physical addresi is: Tom Russell 314 Flying Fish Road Carbondale, CO 81623 970-618-4462 Wright Water Engineers, Inc. surveyed a cross section of the river in line with the 1982 flood plain survey cross section and compared the two. There has been approximately L2 feetof bank erosion toward the house since 1882. 1700 County Rood 103 . Carbondale, Colorodo 8t623 970-c63-1356 Fox:970-963-983e The river has actually decreased in cross sectional area due to bar deposition, which is pushing the river in to the bank in front of the house. Garfield County will not allow the cross section of the river to be decreased any more. Therefore a portion of the bank equal to the rock armor will be removed to an upland site. Normally I would propose deflectors with the rock work to improve fish habitat, however they would decrease the cross sectional area of the river. This is unfortunate since this stretch of the Roaring Fork River is lacking holding cover for fish. It is proposed to plant willow stakes or I quart willows on a 4 foot center along the 150 feet of bank. Due to the dryness of the site it is important that the stakes or roots are in contact with moist soil during the growing season. This may require irrigation. Live stakes shall be prepared from Salix sp. obtained on site or within a 5 mile radius. Cuttings shall be free of disease and past active gowth (approaching or already in dormancy is best). Remaining leaves shall be ,.*ou.d from the stems. The diameter of the cuttings shall not be less than 3/8 inch nor more than 1'/r.inch and shall be a minimum of eighteen inches in lenEh. Cuts shall be made as cleanly as possible to avoid fraying of ends. Ounng preparation, onentation shall be maintained with the tops up and bases down. Top stem cttts shall be flat and bottoms cut on a forry-five degree angle for ease of identi fi cation and installation. Cuttfrgs shall be prepared no longer than one week before planting and shall be maintained in moist conciitions. Stakes may be stored in water filled buckets placed in the shade or in wet burlap under refirgeration (32 to 45 degrees F). Cuttings shall be kept moist during planting Cuttings may be pushed into ground that is soft. Holes on compacted soilsshall be created with rebar or similar devices to avoid damage to bark Cuttings shall be planted so that approximately 213 to 3/4 of the srake isbuned. Two to three rnches shall remain above the ground level. The soil around the cuttings shall be firmly tamped. No air pockets or voids shallremain around the cuttings. The base of the cuttings must intersect groundwater or saturated soil. Disnrbed areas will be seeded with the following seed mixture at the rate of 40 pounds per acre: Sediment control dunng construction will involve the placement of Jersey bamer across hvo inlets to the flow against the bank. They will be wrapped infilter cloth to reduce flow against the bank (see attached diawing) Please give me a call if you liave any questions.
