S.C. Code Ann. § 48-39-290 – Restrictions on construction or reconstruction seaward of the baseline or between the baseline and the setback line; exceptions; special permits

(A) No new construction or reconstruction is allowed seaward of the baseline except:
1. (1) wooden walkways no larger in width than six feet;
2. (2) small wooden decks no larger than one hundred forty-four square feet;
3. (3) fishing piers which are open to the public. Those fishing piers with their associated structures including, but not limited to, baitshops, restrooms, restaurants, and arcades which existed September 21, 1989, may be rebuilt if they are constructed to the same dimensions and utilized for the same purposes and remain open to the public. In addition, those fishing piers with their associated structures which existed on September 21, 1989, that were privately owned, privately maintained, and not open to the public on this date also may be rebuilt and used for the same purposes if they are constructed to the same dimensions;
4. (4) golf courses;
5. (5) normal landscaping;
6. (6) structures specifically permitted by special permit as provided in subsection (D);
7. (7) pools may be reconstructed if they are landward of an existing, functional erosion control structure or device;
8. (8) existing groins may be reconstructed, repaired, and maintained. New groins may only be allowed on beaches that have high erosion rates with erosion threatening existing development or public parks. In addition to these requirements, new groins may be constructed and existing groins may be reconstructed only in furtherance of an on-going beach renourishment effort which meets the criteria set forth in regulations promulgated by the department and in accordance with the following:
  1. (a) The applicant shall institute a monitoring program for the life of the project to measure beach profiles along the groin area and adjacent and downdrift beach areas sufficient to determine erosion/accretion rates. For the first five years of the project, the monitoring program must include, but is not necessarily limited to:
    1. (i) establishment of new monuments;
    2. (ii) determination of the annual volume and transport of sand; and
    3. (iii) annual aerial photographs.
      Subsequent monitoring requirements must be based on results from the first five-year report.
  2. (b) Groins may only be permitted after thorough analysis demonstrates that the groin will not cause a detrimental effect on adjacent or downdrift areas. The applicant shall provide a financially binding commitment, such as a performance bond or letter of credit that is reasonably estimated to cover the cost of reconstructing or removing the groin and/or restoring the affected beach through renourishment pursuant to subsection (c).
  3. (c) If the monitoring program established pursuant to subsection (a) shows an increased erosion rate along adjacent or downdrift beaches that is attributable to a groin, the department must require either that the groin be reconfigured so that the erosion rate on the affected beach does not exceed the pre-construction rate, that the groin be removed, and/or that the beach adversely affected by the groin be restored through renourishment.
  4. (d) Adjacent and downdrift communities and municipalities must be notified by the department of all applications for a groin project.
  5. (e) Nothing in the section shall be construed to create a private cause of action, but nothing in this section shall be construed to limit a cause of action under recognized common law or other statutory theories. The sole remedies, pursuant to this section, are:
    1. (i) the reconstruction or removal of a groin; and/or
    2. (ii) restoration of the adversely affected beach and adjacent real estate through renourishment pursuant to subsection (c).
      An adjacent or downdrift property owner that claims a groin has caused or is causing an adverse impact shall notify the department of such impact. The department shall render an initial determination within sixty (60) days of such notification. Final agency action shall be rendered within twelve months of notification. An aggrieved party may appeal the decision pursuant to the Administrative Procedures Act.
      A permit must be obtained from the department for items (2) through (8).
(B) Construction, reconstruction, or alterations between the baseline and the setback line are governed as follows:
1. (1) Habitable structures:
  1. (a) New habitable structures: If part of a new habitable structure is constructed seaward of the setback line, the owner must certify in writing to the department that the construction meets the following requirements:
    1. (i) The habitable structure is no larger than five thousand square feet of heated space. The structure must be located as far landward on the property as practicable. A drawing must be submitted to the department showing a footprint of the structure on the property, a cross section of the structure, and the structure's relation to property lines and setback lines which may be in effect. No erosion control structure or device may be incorporated as an integral part of a habitable structure constructed pursuant to this section.
    2. (ii) No part of the building is being constructed on the primary oceanfront sand dune or seaward of the baseline.
  2. (b) Habitable structures which existed on the effective date of Act 634 of 1988 or constructed pursuant to this section:
    1. (i) Normal maintenance and repair of habitable structures is allowed without notice to the department.
    2. (ii) Additions to habitable structures are allowed if the additions together with the existing structure do not exceed five thousand square feet of heated space. Additions to habitable structures must comply with the conditions of new habitable structures as set forth in subitem (a).
    3. (iii) Repair or renovation of habitable structures damaged, but not destroyed beyond repair, due to natural or manmade causes is allowed.
    4. (iv) Replacement of habitable structures destroyed beyond repair due to natural causes is allowed after notification is provided by the owner to the department that all of the following requirements are met:
      a. The total square footage of the replaced structure seaward of the setback line does not exceed the total square footage of the original structure seaward of the setback line. The linear footage of the replaced structure parallel to the coast does not exceed the original linear footage parallel to the coast.
      b. The replaced structure is no farther seaward than the original structure.
      c. Where possible, the replaced structure is moved landward of the setback line or, if not possible, then as far landward as is practicable, considering local zoning and parking regulations.
      d. The reconstruction is not seaward of the baseline unless permitted elsewhere in Sections 48-39-250 through 48-39-360.
    5. (v) Replacement of habitable structures destroyed beyond repair due to manmade causes is allowed provided the rebuilt structure is no larger than the original structure it replaces and is constructed as far landward as possible, but the new structure must not be farther seaward than the original structure.
2. (2) Erosion control devices:
  1. (a) No new erosion control structures or devices are allowed seaward of the setback line except to protect a public highway which existed on the effective date of this act.
  2. (b) Erosion control structures or devices which existed on the effective date of this act must not be repaired or replaced if destroyed:
    1. (i) more than eighty percent above grade through June 30, 1995;
    2. (ii) more than sixty-six and two-thirds percent above grade from July 1, 1995, through June 30, 2005;
    3. (iii) more than fifty percent above grade after June 30, 2005.
    4. (iv) Damage to seawalls and bulkheads must be judged on the percent of the structure remaining intact at the time of damage assessment. The portion of the structure or device above grade parallel to the shoreline must be evaluated. The length of the structure or device parallel to the shoreline still intact must be compared to the length of the structure or device parallel to the shoreline which has been destroyed. The length of the structure or device parallel to the shoreline determined to be destroyed divided by the total length of the original structure or device parallel to the shoreline yields the percent destroyed. Those portions of the structure or device standing, cracked or broken piles, whalers, and panels must be assessed on an individual basis to ascertain if these components are repairable or if replacement is required. Revetments must be judged on the extent of displacement of stone, effort required to return these stones to the prestorm event configuration of the structure or device, and ability of the revetment to retain backfill material at the time of damage assessment. If the property owner disagrees with the assessment of a registered professional engineer acting on behalf of the department, he may obtain an assessment by a registered professional engineer to evaluate, as set forth in this item, the damage to the structure or device. If the two assessments differ, then the two engineers who performed the assessments must select a registered professional engineer to perform the third assessment. If the first two engineers are unable to select an engineer to perform the third assessment, the clerk of court of the county where the structure or device lies must make the selection of a registered professional engineer. The determination of percentage of damage by the third engineer is conclusive.
    5. (v) The determination of the degree of destruction must be made on a lot by lot basis by reference to county tax maps.
    6. (vi) Erosion control structures or devices must not be enlarged, strengthened, or rebuilt but may be maintained in their present condition if not destroyed more than the percentage allowed in Section 48-39-290(B)(2)(b)(i), (ii), and (iii). Repairs must be made with materials similar to those of the structure or device being repaired.
  3. (c) Erosion control structures or devices determined to be destroyed more than the percentage allowed in Section 48-39-290(B)(2)(b)(i), (ii), and (iii) must be removed at the owner's expense. Nothing in this section requires the removal of an erosion control structure or a device protecting a public highway which existed on the effective date of Act 634 of 1988.
  4. (d) The provisions of this section do not affect or modify the provisions of Section 48-39-120(C).
  5. (e) Subitem (a) does not apply to a private island with an Atlantic Ocean shoreline of twenty thousand, two hundred ten feet of which twenty thousand, ninety feet of shoreline is revetted with existing erosion control devices and one hundred twenty feet of shoreline is not revetted with existing erosion control devices. Nothing contained in this subitem makes this island eligible for beach renourishment funds.
3. (3) Pools, as defined in Section 48-39-270(12):
  1. (a) No new pools may be constructed seaward of the setback line unless the pool is built landward of an erosion control structure or device which was in existence or permitted on the effective date of this act and is built as far landward as practical.
  2. (b) Normal maintenance and repair is allowed without notice to the department.
  3. (c) If a pool, existing on July 1, 1988, is destroyed beyond repair, as determined by the department pursuant to Section 48-39-270(11), it may be replaced if the owner certifies in writing to the department that:
    1. (i) It is moved as far landward as practical. This determination of practicality must include the consideration of local zoning requirements.
    2. (ii) It is rebuilt no larger than the destroyed pool.
    3. (iii) It is constructed according to acceptable standards of pool construction and cannot be reinforced in a manner so as to act as an erosion control structure or device.
  4. (d) If a pool is not destroyed beyond repair as determined by the department pursuant to Section 48-39-270(11) but the owner wishes to replace it, the owner may do so if:
    1. (i) The dimensions of the pool are not enlarged.
    2. (ii) The construction conforms to sub-subitem (iii) of subitem (c).
4. (4) All other construction or alteration between the baseline and the setback line requires a department permit. However, the department, in its discretion, may issue general permits for construction or alterations where issuance of the general permits would advance the implementation and accomplishment of the goals and purposes of Sections 48-39-250 through 48-39-360.
(C)
1. (1) Notwithstanding the provisions relating to new construction, a person, partnership, or corporation owning real property that is affected by the setback line as established in Section 48-39-280 may proceed with construction pursuant to a valid building permit issued as of the effective date of this section. The person, partnership, or corporation may proceed with the construction of buildings and other elements of a master plan, planned development, or planned unit development notwithstanding the setback line established in this chapter if the person, partnership, or corporation legally has begun a use as evidenced by at least one of the following:
  1. (a) All building permits have been applied for or issued by a local government before July 1, 1988.
  2. (b) There is a master plan, planned development, or planned unit development:
    1. (i) that has been approved in writing by a local government before July 1, 1988; or
    2. (ii) where work has begun pursuant to approval as evidenced by the completion of the utility and infrastructure installation designed to service the real property that is subject to the setback line and included in the approved master plan, planned development, or planned unit development.
2. (2) However, repairs performed on a habitable structure built pursuant to this section are subject to the guidelines for repairs as set forth in this section.
3. (3) Nothing in this section prohibits the construction of fishing piers or structures which enhance beach access seaward of the baseline, if permitted by the department.
(D) Special permits:
1. (1) If an applicant requests a permit to build or rebuild a structure other than an erosion control structure or device seaward of the baseline that is not allowed otherwise pursuant to Sections 48-39-250 through 48-39-360, the department may issue a special permit to the applicant authorizing the construction or reconstruction if the structure is not constructed or reconstructed on a primary oceanfront sand dune or on the active beach and, if the beach erodes to the extent the permitted structure becomes situated on the active beach, the permittee agrees to remove the structure from the active beach if the department orders the removal. However, the use of the property authorized under this provision, in the determination of the department, must not be detrimental to the public health, safety, or welfare.
2. (2) The department's Permitting Committee is the committee to consider applications for special permits.
3. (3) In granting a special permit, the committee may impose reasonable additional conditions and safeguards as, in its judgment, will fulfill the purposes of Sections 48-39-250 through 48-39-360.
4. (4) A party aggrieved by the decision to grant or deny a special permit application may appeal pursuant to Section 48-39-150(D).
(E) The provisions of this section and Section 48-39-280 do not apply to an area in which the erosion of the beaches located in its jurisdiction is attributed to a federally authorized navigation project as documented by the findings of a Section 111 Study conducted under the authority of the federal Rivers and Harbors Act of 1968, as amended by the federal Water Resources Development Act of 1986, and approved by the United States Army Corps of Engineers. Nothing contained in this subsection makes this area ineligible for beach renourishment funds. The baseline determined by the local governing body and the department is the line of erosion control devices and structures and the department retains its jurisdiction seaward of the baseline. In addition, upon completion of a department approved beach renourishment project, including the completion of a sand transfer system if necessary for long-term stabilization, an area under a Section 111 Study becomes subject to all the provisions of this chapter. For the purposes of this section, a beach nourishment project stabilizing the beach exists if a successful restoration project is completed consisting of at least one hundred fifty cubic yards a foot over a length of five and one-half miles, with a project design capable of withstanding a one-in-ten-year storm, as determined by department, and renourishment is conducted annually at a rate, agreed upon by the department and local governing body, equivalent to that which would occur naturally if the navigation project causing the erosion did not exist. If the two parties cannot agree, then the department must obtain the opinion of an independent third party. Any habitable structure located in an area in which the erosion of the beaches located in its jurisdiction is attributed to a federally authorized navigation project as documented by the findings of a Section 111 Study, which was in existence on September 21, 1989, and was over forty years old on that date and is designated by the local governing body as an historical landmark may be rebuilt seaward of the baseline if it is rebuilt to the exact specifications, dimensions, and exterior appearance of the structure as it existed on that date.
