Louisiana has nine watershed regions, with several parishes in each region. The Louisiana Watershed Initiative works to coordinate the efforts of these cities, parishes and regions to reduce flood risks within the state. 

Construction Requirements

Floodplain Management

The Code Enforcement Officer will examine each application for a floodplain development permit, whether for new construction, additions, or repairs, to ensure that the proper standards are met in order to control the threat of damage to life and property by flooding for property owners and their neighbors. 

Risk Evaluation Guidelines:

  • The danger to life and property due to flooding or erosion damage
  • The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner
  • The danger that materials may be swept onto other lands to the injury of others
  • The compatibility of the proposed use with existing and anticipated development
  • The safety of access to the property in times of flood for ordinary and emergency vehicles
  • The costs of providing governmental services during and after flood conditions, including maintenance and repair of streets and bridges and public utilities 
  • The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action expected at the site
  • The necessity of a waterfront location and the availability of alternative, possibly safer, locations for the proposed use

Minimum Requirements for New Construction and/or Substantial Improvements:

  • Must be anchored sufficiently to prevent flotation
  • Shall be constructed using methods that minimize flood damage
  • Shall be constructed using materials resistant to flood damage
  • Electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities must be designed or located so as to prevent water from entering or accumulating within the components
  • Water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system
  • Sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the system as well as discharge from the systems into floodwaters
  • On-site waste disposal systems must be located to avoid impairment to them or contamination from them 

Specific standards for these basic guidelines and more can be found at Leesville, LA Code of Ordinances, Chapter 24, Flood Damage Prevention.

When Flooding Threatens:

Flood Warnings

Citizens are encouraged to sign up for free Nixle alerts from the Vernon Parish Sheriff's Office by dialing 888777 on their cellphone. Once signed up, they will receive a text notification whenever any flood warning is issued for the area by the US National Weather Service. 


To help citizens prepare for flooding threats to their homes, the city often provides sand and bags for citizens in their efforts to prepare for the emergency. You must bring your own shovel and fill your own bags. Sign up for free text or email notifications from this website, and you'll be notified whenever sand is available and where to find it.
