Thinking about adding a dock on the Waccamaw? You are not alone. The river is a major draw in Georgetown County, but the rules can feel confusing if it is your first time dealing with coastal permits. This quick guide will help you understand who reviews your project, what typically triggers permits, how public notice works, and how to plan your timeline so you avoid costly delays. Let’s dive in.
What permits you may need
State review: SCDHEC‑OCRM
If your dock or pier extends waterward of the mean high‑water line or could affect coastal wetlands, the South Carolina Department of Health and Environmental Control’s Office of Ocean and Coastal Resource Management typically reviews it. That includes docks, pilings, gangways, floats, boathouses, boatlifts, and any dredging or fill in tidal waters.
Federal review: U.S. Army Corps of Engineers
The U.S. Army Corps of Engineers regulates work in navigable waters and dredge or fill in waters of the United States. Many dock projects on the Waccamaw, especially those that extend over the river or involve dredging, need federal authorization coordinated with the state review.
Local review: Georgetown County
You may also need county approvals for zoning, shoreline setbacks, or related building and site work. County sign‑off is separate from state and federal reviews, so plan for both.
Other resource agencies
Projects can involve input from the South Carolina Department of Natural Resources and federal wildlife agencies. Their reviews focus on submerged aquatic vegetation, shellfish beds, and habitat for protected species.
When review is triggered
Most residential projects on tidal portions of the Waccamaw will need review if they include any of the following:
- Work waterward of the mean high‑water line.
- Construction of a pier, dock, or boathouse over submerged lands.
- Installation of pilings, gangways, floats, covered structures, or boatlifts over tidal waters.
- Any dredging or placement of fill to create or maintain a slip or access channel.
- Work that could affect submerged aquatic vegetation or shellfish beds.
- Commercial or public‑access uses, or structures larger than small residential thresholds.
Permit types in plain English
Authorization by Rule or exemptions
Some small, residential docks may qualify for a streamlined state authorization if they meet strict size and design limits. Eligibility usually depends on overall footprint, walkway width, slip count and size, no dredging, and separation from sensitive resources. If your design fits these limits, your review is often faster and simpler.
Individual or standard permits
Larger or more complex projects typically require an individual permit with full review and public notice. This includes docks that exceed small‑project thresholds, covered boathouses, multiple slips, and any dredging or work near sensitive habitats.
Public notice explained
If your project needs a full individual permit, the state issues a public notice so neighbors, local governments, and resource agencies can comment. Here is what that looks like:
- The agency checks that your application is complete, including surveys, plans, and habitat information.
- A public notice is posted for a set period. During that window, comments are submitted and become part of the record.
- Some projects require direct notice to adjoining landowners or on‑site posting.
- Agencies may request more information, such as vegetation mapping or studies.
- The state issues a decision that may include conditions to protect navigation, water quality, and resources.
Many smaller, well‑designed residential docks move forward with limited controversy. Larger projects or proposals that include dredging are more likely to draw comments and longer review times.
Timeline: what to expect
- Small projects that clearly meet streamlined criteria can take weeks to a few months, depending on application quality and agency workload.
- Individual permits that involve public notice, interagency coordination, or dredging often take several months, and 4 to 9 months is common for complex cases.
- Federal review or significant public comment can extend timelines further.
Build extra time into your plans and avoid scheduling contractors until you have your written approvals in hand.
Your step‑by‑step checklist
- Get a current boundary and shoreline survey showing the mean high‑water line and property lines.
- Sketch a concept plan with pier alignment, lengths, widths, and any floats, lifts, or covered elements.
- Contact the state coastal office early to ask if your concept can qualify for a streamlined authorization or needs an individual permit. Request current checklists.
- Confirm Georgetown County zoning, setbacks, and any local permits.
- If dredging or a large or covered structure is involved, contact the federal office for guidance and ask about a joint pre‑application meeting.
- Check for submerged aquatic vegetation and shellfish beds. If present or suspected, consult resource agencies early.
- Budget for a qualified marine contractor or permit consultant to prepare plans and help you navigate the process.
Common pitfalls to avoid
- Assuming riparian ownership extends waterward. The area seaward of the mean high‑water line is regulated under public trust rules.
- Starting work before approvals are final. This can lead to stop‑work orders, fines, or required removal.
- Overlooking vegetation or shellfish resources. Discovery during review can require redesign or mitigation.
- Hiring a contractor unfamiliar with South Carolina coastal permitting.
Design tips for Waccamaw sites
- Keep pier alignments and lengths conservative and consistent with nearby docks to minimize navigation concerns.
- Avoid shading sensitive vegetation. Narrower walkways and careful orientation can help.
- Plan for tidal influence and wetlands along the riverbank. Small changes to layout can reduce impacts and improve permitability.
- Be mindful of historic and conservation areas in Georgetown County. These can add conditions or agency coordination.
Documents you will likely need
- Survey locating the mean high‑water line and property corners.
- Site plan with dimensions for walkway, floats, slips, pilings, and distances from shoreline features.
- Statements on potential impacts to submerged vegetation, shellfish, wetlands, and any dredging method and disposal location.
- Construction methods and protective measures such as siltation controls and work windows.
Next steps for buyers and owners
If you are buying riverfront property in Georgetown County, factor dock potential and permit timing into your due diligence. Ask for recent surveys, look for nearby dock patterns, and confirm if a previous permit exists. If you already own, start with a survey and a quick pre‑application call so you can shape your design to fit the right path, whether that is a streamlined authorization or a full individual permit.
Before you build: get a survey showing the mean high‑water line, then contact the state coastal office and Georgetown County to confirm permit needs. Do not build waterward of mean high water without written approvals.

FAQs
Do I need a permit for a small residential dock on the Waccamaw?
- Yes, if any part of the dock extends waterward of the mean high‑water line or could affect tidal wetlands. Some small residential designs may qualify for a streamlined state authorization if they meet strict criteria.
How long do dock permits take in Georgetown County?
- Simple projects that meet streamlined criteria can take weeks to a few months. Individual permits with public notice or dredging often take several months, and 4 to 9 months is common for complex projects.
What if my design includes dredging for a boat slip or access?
- Dredging usually requires an individual state permit and federal authorization. Expect full public notice, interagency coordination, and a longer timeline.
How does public notice work for dock permits on the Waccamaw?
- For individual permits, the state posts a public notice inviting comments from neighbors, local governments, and resource agencies, then issues a decision with any required conditions.
Can I build past the mean high‑water line without approvals?
- No. Work waterward of the mean high‑water line is regulated. Starting construction before approvals can lead to stop‑work orders and costly remediation.
