How to identify wetlands

Wetlands help regulate the quantity of water moving through a watershed by retaining water during wet periods and releasing it during dry periods. A watershed may have a few large wetlands, many smaller ones, or any combination that provides the necessary storage capacity. All wetlands, small or large, are essential to the proper functioning of a watershed. Your wetland, however small, is valuable both for its own intrinsic merits and for its contributions to your watershed.

Volunteer Opportunities

Perhaps the first and biggest benefit people get from volunteering is the satisfaction of incorporating service into their lives and making a difference in their community and country. The intangible benefits alone—such as pride, satisfaction, and accomplishment—are worthwhile reasons to serve. In addition, when we share our time and talents we:

        • Solve problems
        • Strengthen communities
        • Improve lives
        • Connect to others
        • Transform our own lives

While it might be a challenge to coordinate everyone’s schedules, volunteering as a family has many worthwhile benefits. Children watch everything you do. By giving back to the community, you show them firsthand how volunteering makes a difference and how good it feels to help others and enact change. It’s also a valuable way for you to get to know organizations in the community and find resources and activities for your children and family. Here are a few to consider:

Drainage Maintenance

Development projects are designed with specific drainage patterns. Homeowners should maintain and not interfere with any planned drainage patterns. Many stormwater systems are privately owned, including all stormwater ponds. HOAs should periodically inspect their stormwater drainage systems, including ponds, pipes, swales, and ditches. Routine inspections can reveal maintenance needs or minor problems before they become major headaches.

For Horry County's guidebook on maintaining stormwater systems, click here. For US EPA guidance on maintaining stormwater systems, click here. For a slideshow and podcast of a training workshop designed for HOAs, click here. For a sample self-inspection checklist for HOAs, click here. Horry County will periodically inspect neighborhood drainage systems and provide reports to the HOA or property owner. HOAs should prepare for anticipated storms by inspecting their stormwater drainage systems before any storm danger is near. To ensure your safety, do not conduct inspections during a storm. For a sample checklist for pre-storm inspections, click here. Drainage disputes between neighboring property owners are not uncommon.

Easements and Encroachments

Drainage easements are put in place to maintain drainage infrastructure, some of which may be underground. Drainage easements may be public or private and afford the easement holder the right to access the property for only what is expressly enumerate in the easement. Drainage easements typically dictate thing like the repair or maintain drainage infrastructure. The landowner maintains ownership of the property.  The size of an easement is determined by the type of infrastructure within the easement and the type of equipment or materials that may be needed to fix a problem. Encroachments into an easement may interfere with easement access and must be specifically permitted by the easement holder. If a resident would like to do some work in an easement assigned to the county or a "public easement" for example, they would have to submit an encroachment permit to the county. This permit includes things such as location of the site (w/ map), type of material or structure to be put in the easement (w/ map), property owner, contact information, and description of the work to be performed. The encroachment must be signed by the owner of the property. NO second party signatures will be accepted.  Click here for an Horry County encroachment permit form that may be used as a template. It is encouraged for the HOA to use a similar form and the residents use this form to provide you the most accurate information about their project as possible so you may make the best decisions for your community.
