DAKOTA PRAIRIE GRASSLANDS - Magpie Creek Bank Stabilization

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the technical specifications for the Magpie Creek Bank Stabilization project within the Dakota Prairie Grasslands, Medora Ranger District. The primary goal is to stabilize the creek bank.

Key work areas include:

• Mobilization: Moving personnel, equipment, and materials to the site; obtaining permits, insurance, and bonds; and cleaning construction equipment to prevent the spread of noxious weed seeds.

• Excavation and Embankment: This involves excavating material (common, subexcavation, borrow) and constructing embankments. Specific tasks include clearing the area, preparing foundations, constructing embankments in layers, shaping slopes, and finishing the embankment. Material management, including disposal of unsuitable material and use of approved borrow excavation, is detailed.

• Earthwork Geotextiles: Providing and installing geotextile for separation, stabilization, filtration, and reinforcement applications, particularly beneath riprap.

• Riprap: Furnishing and placing angular rock riprap on a prepared surface, with specific gradations and dimensions outlined for Class 2 Riprap.

• Topsoil: Furnishing and placing topsoil 6 inches deep on prepared surfaces, including preparation, placement, and acceptance criteria.

• Seeding and Mulching: Preparing the seedbed, applying seed and straw mulch, and protecting seeded areas until vegetation is established. Specific seeding rates and dates are provided.

• Haul Road Maintenance and Surface Replacement: Maintaining haul roads and resurfacing with 2-inch minus Scoria, including grading and dust abatement.

• Beaver Dam Analogs (BDAs): Constructing low-profile, permeable structures using wooden posts, native woody material, riprap, and native fill to reduce stream velocity and streambank erosion.

• Mobilization Payment: Phased payment based on earned contract amount.

• Measurement and Payment: Work is measured and paid for according to specific pay items in the Schedule of Items, using various units of measurement (e.g., Cubic Yard, Each, Acre, Lump Sum). Payment is generally for accepted quantities at the contract price.

• Embankment Construction: Material placed in horizontal layers not exceeding 12 inches compacted thickness. Embankment surface shaped to drain at the end of each day.

• Seeding: Vegetation considered established when a uniform perennial vegetative cover of 70% density is achieved. Seeding dates are specified (May 15th – June 15th for cool and warm season mixes).

• Acceptance: Generally based on visual inspection for compliance with contract requirements and prevailing industry standards, with CO approval.

• The project is located within the Dakota Prairie Grasslands, Medora Ranger District.

• Specific periods of performance are not detailed in this document, but payment schedules indicate initial seeding/mulching and final acceptance.

• Equipment Cleaning: Construction equipment must be cleaned to prevent the spread of noxious weed seeds.

• Material Approval: CO approval is required for materials, including geotextile, riprap, and borrow excavation sources.

• Geotextile: Specific overlap (24 inches) and keying into the subgrade (2 feet) are required.

• Riprap: Gradation requirements and intermediate dimensions are specified.

• Topsoil: Placement requires at least 2 days' notice and specific conditions regarding ground moisture and temperature.

• Seeding: Specific seed mix guidelines, seeding depth, broadcast seeding multipliers, and dormant seeding considerations are provided.

• Haul Roads: Surfacing with 2-inch minus Scoria and dust abatement are required.

• BDAs: Construction involves specific materials, techniques for weaving and packing, and lift construction.
