About this file
This is a price schedule for a federal contract to remove debris from six aqueducts operated by the C&O Canal Heritage Area (CHOH) in Fiscal Year 2026. The base contract includes twelve line items with firm fixed price compensation across six aqueduct locations: Seneca Creek, Monocacy, Catoctin Creek, Antietam Creek, Conocheague, and Licking Creek. Each location has two associated tasks: Task 1 involves removal of accumulated woody debris fields to a submerged depth of four feet, including debris three inches in diameter and above, as well as fine woody intertwined debris two inches and above; Task 2 involves woody plant and vegetation clearance on aqueduct structures, wing walls, and stone walls using mechanical means and hand tools only, with pruning of tree overhang within thirty feet and remediation of ground damage.
The contract structure includes six optional task orders (Options 1-6) representing a second woody debris removal cycle scheduled for April during flood season. Base tasks 1-12 are priced as firm fixed price contracts, while optional tasks 13-18 utilize a time and material pricing model with estimated labor hours provided by the National Park Service (NPS). Time and material options include specified labor categories (Supervisor, Operator, Laborer) at vendor-provided wage rates and material/equipment not-to-exceed amounts ranging from $1,000 to $30,750 depending on location complexity. The solicitation prohibits chemical agents and dredging operations, requiring operations to minimize riverbed disturbance and preserve stone structure integrity.

SENECA TASK 1 / Remove woody debris accumulation at the Aqueduct structures:
a. Remove all accumulated woody debris fields, to include submerged fields, to a submerged depth of four (4) feet or the river/stream bed floor (whichever occurs first). Include all debris within the extent of the debris field upstream/downstream of the façade of the structure or to next structure (Example Catoctin Creek), or within the structure(s) barrels/arches:
* No dredging is authorized. Operations should be designed to minimize river/stream bed disturbance. If soil mixes with woody debris, it is not considered the river/stream bed and should be treated as such for the removal process.
* No chemicals are authorized for use on the structures. Pesticides, no matter if aquatic- safe or not, can impact the integrity of the stone.
*See Enclosure 1 for example debris fields.
b. Remove all independent/standalone woody debris three (3) inches in diameter and above, to include submerged debris, to a submerged depth of four (4) feet or the river/stream bed floor (whichever occurs first). Include debris within the predetermined distance of the upstream/downstream façade of the structure, or within the structure(s) barrels/arches.
c. Remove all fine woody intertwined debris within the debris field. This includes twigs and woody debris 2 inches and above.
d. Remediate any ground damage incurred during the performance of operations (e.g., ruts, holes, etc.).
e. Remove all wood and debris in accordance with the technical requirements.
