•o US Army Corps of Engineers ~,,~~ ~~ ~~ Sacramento District 1325 J Street Sacramento, CA 95814-2922 III IIIIIIIIIIIII III ~ ~ . u~~~C NOtICe Public Notice Number: 199675208 Date: May 16, 1996 Comments Due: June 15, 1996 In reply, please refer to the Public Notice Number TO WHOM TT MAY CONCERN: SUBJECT: Application for a Department of the Army permit under authority of Section 404 of the Clean Water Act (CWA) and for water quality certification under Section 401 of the CWA to discharge dredged and fill material and continue excavation activities at the North Fork Gunnison River, as shown in the attached drawings. APPLICANT: Farnsworth Construction and Gravel Company, 1494 Highway 133, Paonia, Colorado 81428. LOCATION: The project site is located at the North Fork Gunnison River, approximately 1.0 mile west of the Town of Paonia within Section 1, Township 14 South, Range 92 west, Delta County, Colorado. ' PURPOSE: To place riprap, construct a river crossing and two (2) alluvial berms, and excavate alluvial material form the river for resale as construction materials and aggregate. PROJECT DESCRIPTION: The applicant proposes to annually harvest between 30,000 and 49,000 cubic yards of alluvium from outside the low flow channel of the river. Excavation will be conducted to a depth of 10 feet during low flow periods and will be complimented by the annual construction and removal of temporary alluvial dikes (berms), not to exceed approximate dimensions of 400 feet long, 10 feet wide and,6 feet in height. It is probable that only one berm would be constructed each year to facilitate alternating excavation sites. The berms) would be sited at different locations annually along the affected stream reach on any given harvest year, and removed on an annual basis prior to spring runoff periods. Not more than 400 linear feet of streambank on either bank of the river would be bermed annually. The applicant also proposes to discharge approximately 350 cubic yards of dredged and fill material for construction of a low-water culverted crossing of the river for access between properties located on both banks of the river. Additionally, the applicant also proposes to place 2-foot and greater diameter riprap as needed at critical bank erosion sites. Bank protection will be performed throughout the project area commensurate with erosion protection needs and the availability of suitable riprap material. ALTERNATIVES: An alternatives analysis has not been performed for this project. An analysis will be performed by the applicant and/or the Corps of Engineers prior to issuance of a Department of the Army permit for the proposed project, to determine if there is a less environmentally damaging practicable alternative to the proposed action.
