Land Development Review


Development review for sewage and water supply

Prior to land division or property development actions, Clark County Public Health must determine how sewage treatment and water supply will be provided. A development review ensures that there are adequate systems for sewer treatment (public or on-site) and drinking water supply (individual well, small or large public water systems). The process also ensures that any existing legacy structures (old wells, septic tanks) are safely decommissioned prior to construction.

Below you will find all the forms, and informational guides to assist in your on-site project.  Feel free to contact us if you have any questions by emailing us or calling during regular business hours 564.397.8428.
