Lechuza beach11/2/2022 Our results show that the Hondsbossche Dunes nourishment, built with a natural slope and wide beach, created a positive sediment balance in the dune for a prolonged period after placement. Simultaneously, the dune volume has increased and the dune foot migrated seaward at the entire nourished site, regardless of whether the subaqueous profile gained or lost sediment. The initially wide beaches (i.e., up to 225 m) are reduced to about 100 m-wide. The slope of the surfzone is adjusted within two winters to a similar slope. The man-made cross-shore beach profile rapidly mimics the characteristics of adjacent beaches. However, over the five-year period, net volume losses from the project area were less than 5% of the initial nourished sand volume. A significant coastline curvature is created by the nourishment leading to erosion in the central 7 km bordered by zones with accretion. This paper presents the evolution of this newly created sandy beach system in the first 5 years after implementation based on bathymetric and topographic surveys, acquired every three to six months. The nourishment was built to replace the flood protection function of an old sea-dike while creating additional space for nature and recreation. The Hondsbossche Dunes project is a combined shoreface, beach, and dune nourishment of 35 million m3 sand. These nourishments can be implemented at sandy beach systems, but can also be used to reinforce gray coastal infrastructure (e.g., dams, dikes, seawalls). The temporary gangway/mats would allow seasonal access to the wet sand for people with disabilities and would be removed when conditions are unfavorable.Sandy nourishments can provide additional sediment to the coastal system to maintain its recreational or safety function under rising sea levels. The new parking spaces may require demolition of small improvements in the MRCA easement along East Sea Level Drive. The new parking spaces would include new surfacing and signage, the creation of accessible paths from the spaces to a new viewing platform and temporary gangway at East Sea Level Drive and to the new view area and reconstructed overlook at West Sea Level Drive, and the establishment of a parking access and pass reservation system. Three new parking spaces for people with disabilities would be established along East Sea Level Drive and one near West Sea Level Drive. Improvements include demolition, reconstructing stairs and handrails, limited grading, installing guardrails, stabilizing structures, installing landscaping, a new gate and bike rack at Lot 2 at Broad Beach Road, a new sign at Lot 1 to allow a minor increase of public beach use hours, benches, and kiosk. An existing staircase and pathway to be improved (Lot 1) spans the area from the intersection of Bunnie Lane and Broad Beach Road, south to the beach terminus of East Sea Level Drive. One existing staircase and overlook would be reconstructed at the beach terminus of West Sea Level Drive. #LECHUZA BEACH PORTABLE#The project consists of upgrades and repairs to two existing staircases establishment of four parking spaces for people with disabilities new viewing platform, view area, portable restroom, and temporary beach access gangway/mat and an Initial Management Plan. A public works project to improve safety and accessibility at a public beach.
