MONITORING REPORT - ANNUAL
December 4, 2024
Project Address: 4 Malfa Rd, Yarmouth
DEP File #: SE83-2394
Date of Issuance (NOI): 6/16/2023
Report: #2 (2024)
PROJECT DESCRIPTION:
The approved project allowed for the installation of a coastal adaptation strategy that includes a modest fiber
roll array combined with a reinforced high marsh. These bioengineering installations will both lessen the severity
of erosion of the coastline while providing additional native plant species where none currently exists. Annual
dune nourishment and planting of American beach grass was included to raise the elevation of the existing dune
to conserve this resource area which has been eroding at a short-term rate of four feet per year since 2018. The
proposed coastal adaptation strategy considers the expected sea level rise.
ACTIVITIES TO DATE:
2023 Summer
• Installed the approved fiber roll array and reinforced marsh and nourished the array with compatible
sediment.
• Nourished the coastal dune with compatible sediment and planted American beachgrass throughout the
area of nourishment.
2024
• In the early spring, nourishment was placed over the dune and exposed fiber roll array, and American
beachgrass was planted thought the nourishment. Minor tightening of anchor cables was conducted.
• In the early summer, the specified native plant species were planted into the reinforced marsh.
PROJECT CONDITIONS:
The fiber roll array and reinforced marsh remain in excellent condition and structurally sound after a second year
in the coastal environment. They held up well during the many winter storms that affected the region through the
2023/2024 winter season. A listing of 10 winter storm warnings, coastal flood warning, and high wind warning
is included with this monitoring report. This regional weather trend has caused a greater than typical need for
replacement, repair, and nourishments on all WED coastal stabilization projects. Days that have included Winter
Storm Warning, Coastal Flood Warning, and High Wind Warnings:
2023 - 3 Storms
• November 21st
• December 9th, 18th and 23rd
2024 - 7 Storms
• January 6th, 9th, and 13th
• February 13th, 27th, and 28th
• March - none
• April 12th

PHOTO DOCUMENTATION ON ATTACHED PAGES:
During the December 18th storm event, tidal waters over topped the fiber roll array and eroded the seaward
half of the dune nourishment. The fiber roll array and reinforced marsh performed as designed. The fiber rolls
and anchoring system had no damage and only minor tightening of anchor cables was needed. Coir material
around the reinforced marsh remained intact. Compatible nourishment was placed over the dune and American
beachgrass was planted throughout.
American beach grass along the landward edge of the dune has become established as it enters its second season
following planting. The American beachgrass planted in the spring of 2024 and plant species in the reinforced
marsh were observed to be in good condition. The planted species, dune nourishment, reinforced marsh, and fiber
rolls will contained to be monitored through 2025.
2024/2025 ANTICIPATED ACTIVITIES:
• The dune will be nourished with compatible sediment, as needed, per the approved plan.
• Continued monitoring of the health of the plantings, fiber roll array, and reinforced marsh.
• Submit the 2025 monitoring report.
