About this file

Written by GovTribe AI ·

This document contains engineering drawings and specifications for a Grade Stabilization Structure project to be constructed at the Elk Neck State Forest in Cecil County, Maryland. The project, which is being overseen by the United States Department of Agriculture Natural Resources Conservation Service and the Cecil Soil Conservation District, involves the installation of a 350-foot grassed waterway, a 113-foot 18-inch HDPE pipe drop structure, and associated swales, berms, and rock outlets. The drawings provide detailed design specifications, materials requirements, construction methods, and inspection/approval processes. The contract opportunity, titled "MARTINUK EROSION STABILIZATION @ ELK NECK STATE FOREST", requires the selected contractor to provide all necessary labor, equipment, materials, and insurance to complete the work in accordance with the plans and specifications. No bid due date, award date, or contract term is provided in the document.

The drawings do not contain information about pricing, set-asides, incumbent contractors, funding sources, or other commercial terms. The project appears to be funded through government conservation programs, but the specific funding mechanisms are not detailed. The document focuses solely on the technical and construction requirements for the proposed erosion and stormwater management improvements at the Elk Neck State Forest site.

CONSTRUCTION SPECIFICATIONS

1. USE MATTING THAT HAS A DESIGN VALUE FOR SHEAR STRESS EQUAL TO OR HIGHER THAN THE SHEAR STRESS

DESIGNATED ON APPROVED PLANS.

2. USE TEMPORARY SOIL STABILIZATION MATTING MADE OF DEGRADABLE (LASTS 6 MONTHS MINIMUM) NATURAL OR MAN-MADE FIBERS (MOSTLY ORGANIC). MAT MUST HAVE UNIFORM THICKNESS AND DISTRIBUTION OF FIBERS THROUGHOUT AND BE SMOLDER RESISTANT. CHEMICALS USED IN THE MAT MUST BE NON-LEACHING AND NON-TOXIC TO VEGETATION AND SEED GERMINATION AND NON-INJURIOUS TO THE SKIN. IF PRESENT, NETTING MUST BE EXTRUDED PLASTIC WITH A MAXIMUM MESH OPENING OF 2x2 INCHES AND SUFFICIENTLY BONDED OR SEWN ON 2 INCH CENTERS ALONG LONGITUDINAL AXIS OF THE MATERIAL TO PREVENT SEPARATION OF THE NET FROM THE

PARENT MATERIAL.

3. SECURE MATTING USING STEEL STAPLES, WOOD STAKES, OR BIODEGRADABLE EQUIVALENT. STAPLES MUST BE "U" OR "T" SHAPED STEEL WIRE HAVING A MINIMUM GAUGE OF NO. 11 AND NO. 8 RESPECTIVELY. "U" SHAPED STAPLES

MUST AVERAGE 1 TO 112 INCHES WIDE AND BE A MINIMUM OF

6 INCHES LONG. "T" SHAPED STAPLES MUST HAVE A MINIMUM 8 INCH MAIN LEG, A MINIMUM 1 INCH SECONDARY LEG, AND A MINIMUM 4 INCH HEAD. WOOD STAKES MUST BE ROUGH-SAWN HARDWOOD, 12 TO 24 INCHES IN LENGTH, 1x3

INCH IN CROSS SECTION, AND WEDGE SHAPED AT THE BOTTOM.

4. PERFORM FINAL GRADING, TOPSOIL APPLICATION, SEEDBED PREPARATION, AND PERMANENT SEEDING IN ACCORDANCE WITH SPECIFICATIONS. PLACE MATTING WITHIN 48 HOURS OF COMPLETING SEEDING OPERATIONS UNLESS END OF WORKDAY STABILIZATION IS SPECIFIED ON THE APPROVED EROSION AND SEDIMENT CONTROL

PLAN.

5. UNROLL MATTING IN DIRECTION OF WATER FLOW, CENTERING THE FIRST ROLL ON THE CHANNEL CENTERLINE.

WORK FROM CENTER OF CHANNEL OUTWARD WHEN PLACING ROLLS. LAY MAT SMOOTHLY AND FIRMLY ON THE

SEEDED SURFACE. AVOID STRETCHING THE MATTING.

6. KEY-IN UPSTREAM END OF EACH MAT ROLL BY DIGGING A 6 INCH (MINIMUM) TRENCH AT THE UPSTREAM END OF THE MATTING, PLACING THE ROLL END IN THE TRENCH, STAPLING THE MAT IN PLACE, REPLACING THE EXCAVATED

MATERIAL, AND TAMPING TO SECURE THE MAT END.

7. OVERLAP OR ABUT THE ROLL EDGES PER MANUFACTURER RECOMMENDATIONS. OVERLAP ROLL ENDS BY 6 INCHES

(MINIMUM), WITH THE UPSTREAM MAT OVERLAPPING ON TOP OF THE NEXT DOWNSTREAM MAT.

8. STAPLE/STAKE MAT IN A STAGGERED PATTERN ON 4 FOOT (MAXIMUM) CENTERS THROUGHOUT AND

2 FOOT (MAXIMUM) CENTERS ALONG SEAMS, JOINTS, AND ROLL ENDS.

9. ESTABLISH AND MAINTAIN VEGETATION SO THAT REQUIREMENTS FOR ADEQUATE VEGETATIVE ESTABLISHMENT ARE

CONTINUOUSLY MET IN ACCORDANCE WITH SECTION B-4 VEGETATIVE STABILIZATION.

General notes:

· Remove topsoil prior to grading and stockpile outside limits of waterway construction

· Install excelsior type erosion control matting according to manufacture's recommendations. Matting shall meet minimum shear stress of 1.75 lb/ft² and maximum velocities of 7ft/s (see erosion control matting detail sheet for installation instructions)

· Erosion control matting width shall be a minimum of 2/3 of the waterway width or shown as above

· A minimum of 4" of topsoil shall be placed along entire length and width of constructed waterway

· Lime, fertilizer and seed shall be placed in waterway prior to installing erosion control matting (see seeding details)

· Waterway shall be maintained as needed to minimize erosion throughout the required maintenance life of 10 years
