A concrete bulkhead with riprap bordered 78 ft of the shoreline; the remaining 40 ft was an unarmored beach cove. Almost 50 ft of the hardening was removed, leaving only the below-grade footing in place for structural integrity. A short section of bulkhead was retained to tie into the neighboring property to the north and another portion left to protect a tree at the south end of the shore. Where the bulkhead was removed, the owners re-sloped the bank, revegetated the riparian area with native plants, and added gravel, boulders and logs to the shore.
With 50 feet of armoring removed from the 118-ft shoreline, the project qualified for 25-49% net bulkhead removal. In addition, points were awarded for maintaining and enhancing the unarmored cove that occupied about 34% of the shoreline. The owners included monitoring the shoreline improvements for 5 years in the shoreline maintenance plan.
About 30% of the riparian buffer was revegetated with native plants (about 75% of the shoreline length but only 10-15 ft in width), and a monitoring and maintenance plan for riparian plantings and removal of invasive species was provided. A large tree was protected at the south end of the property that provided the benefits of overhanging vegetation. Large logs were added to the beach to attenuate waves and may also provide some habitat value. The pier and dock are entirely grated, allowing light to penetrate to the water below, and the lighting fixtures direct light laterally and not downward to the water or upward to the sky.
Though over 50% of the lot area is covered in impervious surfaces, almost all the surface runoff is directed to a large cistern and the stored water is used for irrigation and toilet flushing. Any overflow is directed to a rock swale leading to the lakeshore. All materials used for the pier, dock and landscaping are untreated with no paints or stains applied to the surfaces. The shoreline Monitoring and Maintenance Plan excludes the use of chemical pesticides or fertilizer in the shoreline planting area.
The owners kindly allowed this property to be used in testing early versions of the GSH credit and rating system, as well as for training GSH verifiers.
