7. Proactive Development of Coastal Lands
Proactive management occurs in the planning stages of new developments or redevelopments along the shoreline, well before project layout is finalized. This type of planning is beneficial to coastal landowners and developers who are not always aware of shoreline processes, coastal hazards, and the potential impacts of development on the beach and other nearshore areas. The permitting agency should apprise the applicant of the recommendations listed below during project layout. Incorporating the advice of the Planning Department would streamline the permitting process and decrease the risk of coastal hazards.
Developers and landowners should be encouraged to pre-consult with various experts and governmental agencies familiar with coastal erosion in order to get appropriate recommendations on project design. Developers and landowners should also acknowledge that developments along the shoreline are subject to the risk of coastal erosion and high wave events and that any request to protect structures and property with shoreline armoring is currently discretionary based on grounds of hardship and impacts on the environment.
Objectives
7.1) To encourage proactive shoreline developments and increase awareness of coastal hazards7.2) To increase awareness of the discretionary nature of permitting shoreline armoring to protect property
Recommendations
7.1a) Encourage developers and landowners to pre-consult with various experts and governmental agencies familiar with coastal erosion in order to get appropriate recommendations on project design7.1b) Make the Beach Management Plan for Maui available to developers, contractors, and landowners as a reference guide
7.1c) Encourage greater setbacks for erosion hotspots and watchspots and other areas with a high rate of erosion (Figure 14)
7.1d) Discourage slab-on-grade construction (Figure 15)
7.1e) For major condominium/hotel type developments, encourage layouts with less linear frontage (Figures 16, 17, and 18)
7.1f) Encourage minor structures to be non-permanent and portable (Figure 19)
7.1g) Encourage major structures to be hurricane/tsunami resistant (ie., built on posts) (Figure 20) and located away from areas of high coastal hazard
7.1h) Encourage developers to construct building additions on the mauka side of the structure rather than within the shoreline setback area
7.1i) Encourage use of sand fill and native vegetation for shoreline landscaping
7.2a) Require developers and landowners to acknowledge that shoreline armoring is discretionary and based on grounds of hardship and impacts on the environment

Figure 15. Undermined slab on grade sidewalk at Kahekili Park, North Beach, Ka'anapali. This sidewalk is very hazardous to beach users and interferes with coastal processes. This structure should have been readily movable when coastal erosion posed a threat.
Figure 16. Different layouts of shoreline development with varying linear frontage. V-shaped layouts confine the risk of high-wave events and coastal erosion to a small portion of the building instead of the entire structure.
