2. Guidelines for Shoreline Protection Measures
When coastal erosion threatens property, coastal landowners are usually unaware of the different types of coastal protection measures that are available and the applicable environmental concerns and permitting requirements. Since conventional coastal protection structures such as seawalls and revetments have been shown to cause beach narrowing and loss, the County should identify and recommend more environmentally compatible alternatives.
For example, the use of sand bags and large sand-filled geotextile tubes known as sea bags that temporarily control coastal erosion has become popular recently. Another example may be concave or "V" shaped structural hardening designs which may retain sand better than linear structures. This study should discuss how and where these structural alternatives can effectively be used.
Currently, the County of Maui has entered into a contract with Oceanit Laboratories, Inc., to conduct such a study. Oceanit's study is entitled Coastal Protection and Beach Nourishment Study and is expected to be completed by January 1998.
Objective
2.1) To establish guidelines for governmental agencies and the coastal community to determine the most appropriate type of coastal protection in a particular location
Recommendations
2.1a) Develop a study to provide technical recommendations for the restoration of sandy shorelines through beach nourishment2.1b) Provide suggestions on alternative coastal protection designs where beach nourishment is not feasible
2.1c) List acceptable structures for emergency (temporary) coastal protection
2.1d) Address permitting requirements for beach nourishment and structural alternatives
