3.1.4 Zone 4: The Contractor shall provide goats to graze the area described as the Yellowhawk Creek. The total acreage is 2.5 acres. The contractor will be responsible for containing all goats as part of this work.

Grazing does not need to be applied to the entire zone at once and can be accomplished in stages. The adjacent area is open to public access.

Grazing does not need to be applied to the entire zone at once and can be accomplished in stages. The adjacent area is open to public access.

3.1.7 Zone 7: The Contractor shall provide goats to graze the area described as the Forebay. The total acreage is 2.6 acres. This area has a ten-foot-tall wire barrier running down the center. The contractor will be responsible for containing all goats as part of this work. Grazing does not need to be applied to the entire zone at once and can be accomplished in stages. This area will require crossing over Mill Creek on a grating bridge that the Corps will install when the contractor is ready. The Corps will also clear a path large enough for the contractor to install their fence. The adjacent area is open to public access but has very low visitation due to the tall grasses. The contractor will be responsible for notifying the visitors of any hazards associated with their goats through signs. Water will be available where the work zone crosses Mill Creek, and along the southern edge. The Forebay area is dependent on flows being low enough that a bridge can be built for access.

If flows do not get low enough this could be modified out of the call.

3.1.8 Zone 8 (Late Summer Grazing): The Contractor shall provide goats to graze an additional four 2-acre plots anywhere within the Mill Creek Project area. The total acreage is 8 acres but may be expanded or contracted depending on changing vegetative growth and needs of the Project depending on the grazing year.

Additional costs for expanding the area will be proportional to the bid received for this contract.

Time frame for the grazing will be determined each year depending on plant growth and weather. Late Summer Grazing should take place after the flood control grazing. The start timeframe for this grazing will be after the start of teasel bloom but before the majority of the bloom ends.

The main focus of this grazing is to remove invasive species such as, but not limited to, star thistle, teasel, Japanese knotweed, Himalayan blackberry, poison hemlock, cocklebur and/or white byrnie. The contractor will be responsible for containing all goats as part of this work. Grazing does not need to be applied to the entire area at once and can be accomplished in stages. The potential areas range from steep and narrow to flat.
