Construction Requirements

647.03 Drain Dip. Perform roadway excavation and embankment construction to grade trail tread as shown in the plans and according to Section 204. Place select borrow at a 12-inch depth as shown in the plans and according to Section 204.

Excavate rock spillway area constructing horizontal bench according to Section 204 and as shown in the plans. Place separation-stabilization geotextile according to Section 207. Hand place rock spillway using riprap by placing larger rocks on the bottom and filling voids with rocks according to Section 251. Do not break, jar, or displace riprap already set.

647.04 Stream Ford. Obtain approval from the CO before operating equipment in wetted areas. Hand place rock dam, stepping stones, and rock retainer using riprap as shown in the plans and according to Section 251. Perform roadway excavation to grade ford approach and transition areas as shown in the plans and according to Section 204. As shown in the plans, prepare and finish trail bed by placing separation-stabilization geotextile according to Section 207, aggregate base at a 6-inch depth according to Section 301, and select borrow at a 2-inch depth according to Section 204.

Ensure all reasonable measures are taken to prevent the spillage or leakage of any chemicals, oil, grease, gasoline, diesel, or other fuels.

Do not exceed the limits of disturbance as shown in the plans.

647.05 Water Bar. Perform roadway excavation and embankment construction on trailway according to Section 204. Place rocks at a relatively even height and with no exposed sharp edges, creating a water bar as shown in the plans. Ensuring the rocks are tightly imbedded into the trail tread, backfill and compact material that is free of rocks larger than 3 inches in size around rocks as shown in the plans and according to Section 204. Ensure the downgrade trail tread abuts flush to the top of the water bar. Ensure the upgrade trail tread is uniformly out-sloped at a slope equal to or greater than the trail tread to form a gutter against the water bar.

Excavate rock spillway area while constructing horizontal bench according to Section 204 and as shown in the plans. Place separation-stabilization geotextile according to Section 207. Hand place rock spillway using riprap by placing larger rocks on the bottom and filling voids with rocks according to Section 251. Do not break, jar, or displace riprap already set.

647.06 Acceptance. Materials for drain dips, stream fords, and water bars will be evaluated under Subsections 106.02 and 106.03.

Embankment construction, roadway excavation, and select borrow will be evaluated under Section 204.

Geotextile will be evaluated under Section 207.

Riprap will be evaluated under Section 251.
