Installation Guidelines of RECPs during
Shoreline Applications
Step One:
Site Preparation - The first step in the installation of RECPs on shorelines is site preparation. Be sure the site is properly prepared before installing any RECP. The site should be fine graded to a smooth profile and relatively free from all weeds, clods, stones, roots, sticks, rivulets, gullies, crusting and caking. Fill any voids and make sure that the slope is compacted properly.
Step Two:
Seeding - The second step in the installation process of RECPs on shorelines is to seed the area to be vegetated. Select a seed mix for vegetation adapted to the local geographical area. The seed must also be suitable for site-specific soil conditions.
Always match the seed to site soil conditions for optimum germination, root system development, vegetation density, and long term functionality. Prior to RECP installation if the prepared seed bed becomes crusted or eroded, or if eroded places, ruts or depressions exist for any reason, the contractor must rework the soil until it is smooth and re-seed such areas which are reworked.
Step Three:
Prepare the Anchor Trench - At the top of the shoreline dig an anchor trench six-inches deep by six-inches wide. The RECP will be anchored in this trench with staples.
Ideally, allow at least three feet from the crest of the shoreline to the anchor trench. This may not be possible due to site conditions or other factors. The three-foot wide clearance between the shoreline crest and the anchor trench is most beneficial when runoff exists from higher ground. When an RECP is installed on the flat over the crest of the final grade, it will help prevent water from getting under the RECP and causing soil erosion. Staples should be installed across the top of the RECP, one foot on center along the outside parameter of the RECP.
Step Four:
Secure the RECP in the Anchor Trench - Anchor the RECP with staples in the anchor trench. The Federal Highway Administration proposed FP-03 Specifications suggest that the RECP be fastened using staples or stakes 12 inches on center. ECTC suggests that you use this as a guideline, but take RECP type, soil and site conditions into consideration when securing the RECP into the anchor trench. Be sure to drive staples or stakes flush with the soil surface.
Backfill the anchor trench and compact the soil. Place seed over the compacted soil. Cover the compacted soil with the remaining 12 inches of the terminal end of the RECP. Staple or stake terminal end down slope of the anchor trench on 12-inch centers
Step Five:
RECP Deployment - Starting at the crest of the shoreline, roll the RECP down the slope and onto the shoreline in a controlled manner. The best way is for the installer to be on the downside of the slope in front of the RECP and walk the roll down the slope with each backward step. Approximately every 20 feet to 25 feet pull the RECP to take out any excess slack. Do not over stretch the RECP as this may cause bridging of the RECP over the soil surface. The goal is to have the RECPs contour and have intimate contact with the soil. For shoreline applications it is recommended to overlap RECPs and the typical overlap is two to four inches.
Step Six:
Staple or Stake the RECP - Secure the overlap. The typical installation will require one staple be placed at three to five feet intervals along the vertical length of the RECPs. Staples should be staggered every 18 inches to 24 inches horizontally across the RECP.
Step Seven:
Securing the RECP at the Slope Toe - Roll the RECP two feet past the toe of the slope. Secure with staples or stakes one foot on center across the RECP.
