§ 60-2 Development standards in the critical area.

A. General requirements in all Critical Area Overlay Zones.

(1) New solid or hazardous waste collection or disposal facilities, or sanitary landfills or rubble fills, including transfer stations, may not be permitted in the critical area unless no environmentally preferable alternative exists outside the critical area, and these development activities or facilities are needed in order to correct an existing water quality wastewater management problem. Existing permitted facilities shall be subject to the standards and requirements of the Department of the Environment.

(2) Development and redevelopment shall be subject to the Habitat Protection Area (HPA) requirements prescribed in this chapter.

(3) Development and redevelopment shall be subject to the water-dependent facilities requirements of this chapter.

(4) Utility transmission facilities.

(a) Utility transmission facilities, except those necessary to serve permitted uses, or where regional or interstate facilities must cross tidal waters, may be permitted in the critical area, provided:

[1] The facilities are located in IDAs; and

[2] Only after the activity or facility has demonstrated to all appropriate local and state permitting agencies that there will be a net improvement in water quality to the adjacent body of water.

(b) These provisions do not include power plants.

(5) Roads, bridges, and utilities are prohibited in an HPA unless no feasible alternative exists. If a road, bridge or utility is authorized, the design, construction and maintenance shall:

(a) Provide maximum erosion protection;

(b) Minimize negative impacts on wildlife, aquatic life, and their habitats; and

(c) Maintain hydrologic processes and water quality.

(6) All development activities that must cross or affect streams shall be designed to:

(a) Reduce increases in flood frequency and severity that are attributable to development;

(b) Retain tree canopy so as to maintain stream water temperature within normal variation;

(c) Provide a natural substrate for stream beds; and

(d) Minimize adverse water quality and quantity impacts of stormwater.

(7) Reasonable accommodations for the needs of disabled citizens.

(a) An applicant seeking relief from the critical area standards contained in this chapter in order to accommodate the reasonable needs of disabled citizens shall have the burden of demonstrating by a preponderance of evidence the following:

[1] The alterations will benefit persons with a disability within the meaning of the Americans with Disabilities Act;[1]

[1] Editor's Note: See 42 U.S.C. § 12101 et seq.

[2] Literal enforcement of the provisions of this chapter would result in discrimination by virtue of such disability or deprive a disabled resident or user of the reasonable use and enjoyment of the property;

[3] A reasonable accommodation would reduce or eliminate the discriminatory effect of the provisions of this chapter or restore the disabled resident's or user's reasonable use or enjoyment of the property;

[4] The accommodation requested will not substantially impair the purpose, intent, or effect of the provisions of this chapter as applied to the property; and

[5] The accommodation would be environmentally neutral with no greater negative impact on the environment than the literal enforcement of the statute, ordinance, regulation or other requirement; or would allow only the minimum environmental changes necessary to address the needs resulting from the particular disability of the applicant/appellant.

(b) The Planning and Zoning Commission shall determine the nature and scope of any accommodation under this chapter and may award different or other relief than requested after giving due regard to the purpose, intent, or effect of the applicable provisions of this chapter. The Planning and Zoning Commission may also consider the size, location, and type of accommodation proposed and whether alternatives exist which accommodate the need with less adverse effect.

(c) The Planning and Zoning Commission may require, as a condition of approval, that upon termination of the need for accommodation, the property be restored to comply with all applicable provisions of this chapter. Appropriate bonds may be collected or liens placed in order to ensure the Town's ability to restore the property should the applicant fail to do so.

(8) Non-water-dependent structures on piers.

(a) Except as provided in Subsection A(8)(b) of this section and notwithstanding any other provisions of the law, the Town may not issue a building permit or any other approval to authorize a non-water-dependent project located on state or private wetlands within the critical area.

(e) If the Planning and Zoning Commission or its designee makes the findings set forth in Subsection C(3)(d) above and authorizes an applicant to use the lot coverage limits set forth in that subsection, the applicant shall:

[1] Demonstrate that water quality impacts associated with runoff from the development activities that contribute to lot coverage have been minimized through site design considerations or the use of best management practices to improve water quality; and

[2] Provide on-site mitigation in the form of plantings to offset potential adverse water quality impacts from the development activities resulting in new lot coverage. The plantings shall be equal to two times the area of the development activity.

[3] If the applicant cannot provide appropriate stormwater treatment and plantings due to site constraints, then the applicant shall pay a fee to the Town in lieu of performing the on-site mitigation.

(4) The alteration of forest and developed woodlands shall be restricted and mitigated as follows:

(a) The total acreage in forest and developed woodlands within the critical area shall be maintained or preferably increased;

(b) All forests and developed woodlands that are allowed to be cleared or developed shall be replaced in the critical area on not less than an equal-area basis;

(c) If an applicant is authorized to clear more than 20% of a forest or developed woodlands on a lot or parcel, the applicant shall replace the forest or developed woodlands at 1.5 times the areal extent of the forest or developed woodlands cleared, including the first 20% of the forest or developed woodlands cleared.

(d) An applicant may not clear more than 30% of a forest or developed woodlands on a lot or parcel, unless the Board of Appeals grants a variance and the applicant replaces forest or developed woodlands at a rate of three times the areal extent of the forest or developed woodlands cleared.

(c) Clearing of forest or developed woodlands that exceed the maximum area allowed in Subsection C(4) above shall be replanted at three times the areal extent of the cleared forest;

(d) If the areal extent of the site limits the application of the afforestation or reforestation standards in this section, the applicant may be allowed to plant offsite or pay a fee in lieu of planting.

(6) If no forest exists on proposed development sites, these sites shall be planted to provide a forest or developed woodland cover of at least 15%. The applicant shall designate, subject to the approval of the Town, a new forest area on a part of the site not forested.

(7) All forest, including afforested areas, shall be maintained through conservation easements, restricted covenants, or other protective instruments.

(8) New, expanded or redeveloped industrial facilities may only be permitted in LDA if such a use is permitted in the underlying zoning district and provided such facilities meet all requirements for development in the LDA.

D. Resource Conservation Areas (RCA).

(1) Nothing in this section shall limit the ability of a participant in any agricultural easement program to convey real property encumbered with such an easement to family members, provided that no such conveyance will result in a density greater than one dwelling unit per 20 acres.

(2) Land use management practices shall be consistent with the policies and criteria for the HPA provisions of this chapter.

(3) Development activity within the RCAs shall be consistent with the requirements and standards for LDAs as specified in this chapter.

(a) For the purposes of calculating limitations on lot coverage, is as follows:

[1] When a site is mapped entirely as RCA, lot coverage is based on the entire site area; and

[2] When a portion of a lot or parcel is mapped as RCA, lot coverage is based on the area of the RCA.

(4) Density.

(a) Land within the RCA may be developed for residential uses at a density not to exceed one dwelling unit per 20 acres. In calculating the one-in-twenty-acre density of development that is permitted on a parcel located within the RCA, the Town:

[1] Shall count each dwelling unit; and

[2] May permit the area of any private wetlands located on the property to be included under the following conditions:

[a] The density of development on the upland portion of the parcel may not exceed one dwelling unit per eight acres; and

[b] The area of private wetlands shall be estimated on the basis of vegetative information as designated on the state wetlands maps or by private survey approved by the Town, the Critical Area Commission, and Maryland Department of the Environment.

(b) One additional dwelling unit (accessory dwelling unit) as part of a primary dwelling unit may be permitted in the RCA, provided the additional dwelling unit is served by the same sewage disposal system as the primary dwelling unit and:

[1] Is located within the primary dwelling unit or its entire perimeter is within 100 feet of the primary dwelling unit and does not exceed 900 square feet in total enclosed areas; or

(5) Variances to other local setback requirements shall be considered before additional intrusion into the buffer is permitted.

(6) Development and redevelopment may not impact any HPA other than the buffer, including nontidal wetlands, other state or federal permits notwithstanding.

(7) Modified buffer area designation shall not be used to facilitate the filling of tidal wetlands that are contiguous to the buffer or to create additional buildable land for new development or redevelopment.

(8) No natural vegetation may be removed in the buffer except that required by the proposed construction.

(9) Mitigation for development or redevelopment in the MBA approved under the provisions of this subsection shall be implemented as follows:

(a) Natural forest vegetation of an area twice the extent of the footprint of the development activity within the 100-foot buffer shall be planted on-site in the buffer or at another location approved by the Mayor and Town Council.

(b) Applicants who cannot fully comply with the planting requirement in Subsection B(9)(a), above, may offset the mitigation requirement by removing an equivalent area of existing lot coverage in the buffer.

(c) Applicants who cannot comply with either the planting or offset requirements in Subsection B(9)(a) or (b) above shall pay into a fee-in-lieu program as follows:

[1] Applicants shall submit to the Mayor and Town Council two cost estimates from qualified landscape businesses for planting the equivalent of twice the extent of the development within the buffer. The estimate shall include the cost of stock, planting, staking, mulching and a one-year guarantee.

[2] The Mayor and Town Council shall determine the amount of the fee in lieu based on the average of the two estimates.

(d) Any fees in lieu collected under these provisions shall be placed in an account that will assure their use only for projects within the critical area to enhance wildlife habitat, improve water quality, or otherwise promote the goals of the Town's Critical Area Program. The funds cannot be used to accomplish a project or measure that would have been required under existing local, state, or federal laws, regulations, statutes, or permits. The status of these funds must be reported in the jurisdiction's quarterly reports.

(e) Any required mitigation or offset areas shall be protected from future development through an easement, development agreement, plat notes or other instrument and recorded among the land records for St. Mary's County.

§ 60-9 Variances.

A. Applicability. The Town has established provisions where, owing to special features of a site or other circumstances, implementation of this chapter or a literal enforcement of provisions within this chapter would result in unwarranted hardship to an applicant, a critical area variance may be obtained.

(1) In considering an application for a variance, the Town shall presume that the specific development activity in the critical area, that is subject to the application and for which a variance is required, does not conform with the general purpose and intent of Natural Resources Article Title 8, Subtitle 18, Annotated Code of Maryland, COMAR Title 27, and the requirements of this chapter.

(2) Unwarranted hardship means that without a variance, an applicant would be denied reasonable and significant use of the entire parcel or lot for which the variance is requested.

B. Standing. In accordance with Natural Resources Article § 8-1808(d)(2), Annotated Code of Maryland, if a person meets the threshold standing requirements under federal law, the person shall have standing to participate as a party in a local administrative proceeding.

C. Standards. The provisions for granting such a variance shall include evidence submitted by the applicant that the following standards are met:

(1) Due to special features of the site or special conditions or circumstances peculiar to the land or structure involved, a literal enforcement of provisions and requirements of this chapter would result in unwarranted hardship;

(2) A literal interpretation of the provisions of this chapter will deprive the applicant the use of land or a structure permitted to others in accordance with the provisions of this chapter;

(3) The granting of a variance will not confer upon an applicant any special privilege that would be denied by this chapter to other lands or structures within the critical area;

(4) The variance request is not based upon conditions or circumstances which are the result of actions by the applicant, including the commencement of development activity before an application for a variance has been filed;

(5) The request does not arise from any condition relating to land or building use, either permitted or nonconforming on any neighboring property;

(6) The granting of a variance shall not adversely affect water quality or adversely impact fish, wildlife or plant habitat within the critical area; and

(7) The granting of the variance will be in harmony with the general spirit and intent of the State Critical Area Law and this chapter.

D. Process. Applications for a variance will be made in writing to the Board of Appeals with a copy provided to the Critical Area Commission. The Town shall follow its established procedures for advertising and notification of affected landowners.

(1) After hearing an application for a Critical Area Program variance, the Board of Appeals shall make written findings reflecting analysis of each standard. With due regard for the person's technical competence, and specialized knowledge, the written findings may be based on evidence introduced and testimony presented by:

(a) The applicant;

(b) The Town or any other government agency; or

(c) Any other person deemed appropriate by the Board of Appeals.

(2) If the variance request is based on conditions or circumstances that are the result of actions by the applicant, the Board of Appeals shall consider that fact, and whether the application has met the requirements of Subsection E below.

(3) The applicant has the burden of proof and the burden of persuasion to overcome the presumption of nonconformance established in Subsection A above.

(4) Within 10 working days after issuance of a written variance decision, the Board of Appeals shall notify the Critical Area Commission of its findings and decision to grant or deny the variance request.

E. After-the-fact requests.

(1) The Town may not accept an application of a variance to legalize a violation of this subtitle, including an unpermitted structure or other development activity until the local jurisdiction:

(a) Issues a notice of violation; and

(b) Assesses an administrative or civil penalty for the violation.

(2) The Town may not approve an after-the-fact variance unless an applicant has:

(a) Fully paid all administrative, civil and criminal penalties imposed under Natural Resources Article § 8-1808(c)(1)(iii) 14-15 and (2)(i), Annotated Code of Maryland;

(b) Prepared a restoration or mitigation plan, approved by the Town, to abate impacts to water quality or natural resources as a result of the violation; and

(c) Performed the abatement measures in the approved plan in accordance with the local Critical Area Program.

(3) If the Board of Appeals denies the requested after-the-fact variance, then the Town shall:

(a) Order removal or relocation of any structure; and

(b) Order restoration of the affected resources.

(4) Application for an after-the-fact variance constitutes a waiver of the right to appeal the terms of a notice of violation and its final adjudication, including the payment of any penalties and costs assessed.

F. Appeals. Appeals from decision concerning the granting or denial of a variance under these regulations shall be taken in accordance with all applicable laws and procedures of the Town for variances. Variance decisions by the Board of Appeals may be appealed to the Circuit Court of St. Mary's County in accordance with the Maryland Rules of Procedure. Appeals may be taken by any person, firm, corporation, or governmental agency aggrieved or adversely affected by any decision made under this chapter.

G. Conditions and mitigation. The Board of Appeals shall impose conditions on the use or development of a property which is granted a variance as it may find reasonable to ensure that the spirit and intent of this chapter is maintained, including, but not limited to, the following:

(1) Adverse impacts resulting from the granting of the variance shall be mitigated as recommended by the Town Administrator or his/her designee, but not less than by planting on the site per square foot of the variance granted at no less than a 3:1 basis.

(2) New or expanded structures or lot coverage shall be located the greatest possible distance from mean high water, the landward edge of tidal wetlands, tributary streams, nontidal wetlands, or steep slopes.
