Land-use classification | Description | Coastal buffer zone requirement1 | Construction setback requirement1 | OWTS setback requirement1 | Nitrogen reducing technology requirement1,2 |
Developed beyond carrying capacity | Lands developed or undeveloped at < 80,000 square feet [SE or Var] | Coastal buffer based on §1.1.11 of this Part [Var] | Coastal buffer plus 25 feet | Nitrogen reducing technology required [SE, Var] | New OWTS installations or alteration 4 [SE, Var] |
Critical concern | Lands developed or undeveloped at 120,000 square feet and have sensitive salt pond or watershed resources [SE or Var] | 200 feet [SE or Var] | Coastal buffer plus 25 feet | 225 feet [SE, Var] | Lands subdivided after adoption of SAMP that do not meet the CRMC density requirement and substandard lots of record [SE, Var]. |
Self-sustaining | Lands developed, undeveloped at 80,000 square feet [SE or Var] | 150feet [SE or Var] | Coastal buffer plus 25 feet | 200 feet [SE, Var] | Lands subdivided after adoption of SAMP that do not meet the CRMC density requirement and substandard lots of record [SE, Var]. |
[SE or Var] indicates if relief from the requirement or regulations requires a special exception, variance or both. | |||||
1 - CRMC land use classification requirements for density, setbacks, buffer zones and nitrogen reducing technologies are for activities within CRMC jurisdiction (See §§ 4.4(B)(3) and 4.4(B)(4) of this Part) | |||||
2 - A special exception is required for relief from the density requirement, coastal buffer, construction setback, OWTS setback or nitrogen reducing technology requirement unless the lot is pre-platted and cannot accommodate the requirement. | |||||
3 - Nitrogen reducing technologies are defined in § 4.3 of this Part. | |||||
4 - As defined by Department of Environmental Management "Rules Establishing Minimum Standards Relating to Location, Design, Construction and Maintenance of Onsite Wastewater Treatment Systems" |
