At least two stakes shall be used and placed so that the tree grows vertically straight. Put the stake firmly in the ground, while assuring that it is not penetrating or damaging the root ball. Ties shall be of three-quarter inch or wider bands of polypropylene, elasticized or webbed strapping, or horticultural tape. Ties shall have a smooth surface and be flexible to allow some movement of the trunk without damaging the bark. Loop ties to and not girdle the trunks or branches. The CONTRACTOR is responsible for removing stakes and support of the tree after one year installation. 6.01. F. Fencing. All planted ball and burlap trees shall have small mammal protective fencing. Fencing shall be 14 gauge welded wire, or chicken wire with less than 6 inch spacing. The welded wire shall be held 6 inches from the truck and placed as a cylinder around the trunk of the tree at a minimum of 4 feet in height. The welded wire shall be fastened to hardwood stakes with cord. The welded fencing shall be flush with the ground. 6.02 EROSION CONTROL BLANKET All Natural biodegradable Erosion Control Blankets (ECB) shall be placed on all disturbed slopes greater than 10 percent grade. Material shall be North American Green/Tensar(800-772- 2040) SCI5OBN, or approved equivalent that is all natural coir fabric with a tensile strength 201 lbs/ft MD / 164 lbs/ft TD, a permissible shear force of 2.1 lbs/sqft, and mass of 8.3 oz/sqyd. CONTRACTOR shall submit material specification for the chosen ECB to ENGINEER for approval. Install per manufactures recommendations. Store all coir fabric elevated off the ground and insure that it is adequately covered to protect the material from damage. Protect fabric from sharp objects that may damage the material. Materials damaged during transport, storage or placement shall be replaced at the CONTRACTOR expense. The ENGINEER shall inspect and approve all materials prior to installation. TS-45 6.03 TOP SOIL Topsoil shall be salvaged a minimum of 6 inches in depth from all disturbed areas. Salvaged topsoil shall be stockpiled in areas that shall not interfere with construction phases and at least 15 feet away from areas of concentrated flows or pavement. The slopes of the stockpile shall not exceed 2:1 horizontal to vertical. A silt fence or other adequate erosion control shall be installed around the perimeter of each stockpile. 6.03.A. Top Soil Application. Top soil shall be applied to all areas for seeding and planting. Top soil shall be applied at a minimum of 6 inches depth on all seeded areas,and shall be used to backfill all shrub and tree plantings to the depth and twice the width of the root ball. Topsoil shall not be placed when the ground or Topsoil is frozen, or excessively wet. Following the spreading operation, the Topsoil surface shall be raked to final grades without surface irregularities that could contribute to concentrated waterflow downslope. Top soil shall be raked with 0.5 inch undulations for a seed bed. 6.03.B. Top Soil Material. Imported topsoil shall be a natural sandy loam that is weed free. Imported Topsoil shall be properly stored and protected, and shall be free of roots, hard clay and stones which shall not pass through a 1-inch square opening. It shall be a loamy mixture having at least 90 percent passing No. 10 sieve. Below lists the soil properties: 1. Contain no less than 2 percent nor more than 13 percent organic matter, as determined by the test for organic matter in accordance with ASTM D2974. 2. Contain no less than 12 percent or more than 40 percent clay, as determined in accordance with ASTM D422. 3. Sand content shall not exceed 55 percent, as determined in accordance with ASTM D422. 4. The pH shall not be lower than 5.0 or higher than 8.0. The pH shall be determined with an acceptable pH meter on that portion of the sample passing the No. 10 sieve, in accordance with the—Suggested Methods of Tests for Hydrogen Ion Concentration(pH) of Soils, included in the ASTM Procedures for Testing Soils issued December 1964. 5. One hundred percent shall pass the I-inch screen; 97-100 percent shall pass the 1.5- inch screen,and 40-60 percent shall pass the No. 100 mesh sieve. 6. Topsoil shall be free of clods, gravel, and other inert material. It shall be free of thistle, reed canary grass, creeping foxtail, noxious vegetation and seed. Should such regenerative material be present in the soil, the CONTRACTOR shall remove, at his expense and in a manner satisfactory to the Owner's Representative, all such growth, both surface and root, which may appear in the imported Topsoil within 1 year following acceptance of the work. 7. All soil to be seeded shall be amended with Humate and fertilizer product. The method of incorporation of amendments shall result in a uniform application of material as approved. Humate shall be applied at a rate of 1500 pounds per acre. The humate shall be TS-46 applied using approximately 1 gallon of water for 1 pound of dry powder.

The OWNER's goal is to complete the in-water work within this timeframe. Because flow conditions during this timeframe may vary, the OWNER's representative has negotiated with CPW to allow in-water work from October 1 through February 15. If flow conditions are consistently above 250 cfs at the start of the standard/authorized in-water work window and delay the start of in-water construction, the CONTRACTOR may request an extension in writing to CPW. Construction periods for work outside of the main channel shall be scheduled with Town of Basalt and Pitkin County. All out of channel work is to be completed by April 15, 2017. The date of beginning and the time for completion of the work are essential conditions of the Contract Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed. The Contractor will proceed with the work at such rate of progress to ensure full completion within the Contract time. It is expressly understood and agreed, by and between the Contractor and the Owner, that the Contract time for the completion of the work described herein is a reasonable time, taking into consideration the climatic and other factors prevailing in the locality of the work. Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in the bid, quote or proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the vicinity of the Project site during the times of year that the construction will be carried out. Contractor acknowledges that the Project site is located in a high altitude environment where weather patterns can be variable and extreme during winter months. Freezing conditions are likely to be regularly encountered during the construction window. Frazil ice is a winter occurrence throughout much of the Roaring Fork River in Colorado. Ice can pile up significantly on many in-channel obstructions. Contractor is wholly responsible for maintaining conditions that prevent buildup of ice during construction and for delays associated with ice. TS-55 SECTION 9 DEFINITIONS B-Axis The intermediate (and overturning)axis on a boulder. Best Management Practices(BMPs) Water and Soil Care Measures designed to prevent sediment soil erosion, minimize turbidity and protect wetlands. Coffer Dam Structure used to isolate an area for dewatering. Ordinary High Water Line(OHWL) Approximate Water Surface Elevation at the 1 Y2 year Flood. In-Channel Work SII construction work occurring below the ordinary high water line or one and a half year flood or in a wet channel. Invert The cross-section that controls water flow. On-Shore Work All construction work occurring above the ordinary high water line or one and a half year flood. Protect-In-Place Protection of Structures or Vegetation by not disturbing them with adjacent construction activities. Thalweg Lowest elevation of the rive channel in cross section perpendicular to the direction of the main current flow. Toe Point where a ground slope meets a low point and flattens out. Most commonly in rivers it refers to the point where the bank slope meets the channel bottom slope. River Right The right side of the channel when looking downstream. River Left The left side of the channel when looking downstream. Riparian Vegetation Vegetation which is rooted in the eater table of the adjacent riser. Water Surface Elevation Elevation on the project datum, of the surface of water at a specified location.
