33-1 - Findings and purpose.

Local use regulation of watercraft in the waters of this state are authorized by sections 268 and 660 of the California Harbors and Navigation Code in the areas of time-of-day restrictions, speed zones, special-use areas, and sanitation and pollution control.

The purpose of this chapter is to reduce existing conflicts and limit potential conflicts between uses of the shoreline waters, estuaries and coastline of the town, eliminate adverse impacts to the diverse and unusual species found in these areas, promote overall public safety, and decrease hydrocarbon pollution that is disproportionately caused by personal watercraft. A further purpose of this chapter is to assist the County of Marin in protecting and preserving its shoreline areas by promoting consistent regulation of such areas in the county.

Conflicts between uses have the potential to increase in the future because of increasing use of the town's marine waters as well as use and development of shoreline areas. Examples of conflicts that currently occur in addition to fish, marine mammal and wildlife habitat disruption are those between personal watercraft and individuals engaged in water sports such as kayaking, windsurfing, swimming, and canoeing, due to the nature and design of personal watercraft including high maneuverability, high speed, ability to travel in shallow areas, and noise patterns that are unique and annoying.

These same unique characteristics of personal watercraft also cause conflicts between shoreline uses in areas zoned for residential and open space activities.
