The purpose of these provisions is to provide for certain uses which cannot be well adjusted to their environment in particular locations with full protection offered to surrounding properties by rigid application of the district regulations. These uses are generally of a public or semipublic character and are essential and desirable for the general convenience and welfare but, because of the nature of the use, the importance of relationship to the Comprehensive Plan and the possible impact, not only on neighboring properties but on a large section of the Town, require the exercise of planning judgment on locations and site plans.

The following structures and uses shall be approved by the Board of Appeals as conditional uses in this district, except as otherwise provided in accordance with the procedures and standards of this chapter, provided that the location is appropriate and not in conflict with the Comprehensive Plan; that the public health, safety, morals, and general welfare will not be adversely affected; that adequate off-street parking facilities will be provided; and that necessary safeguards will be provided for the protection of surrounding property, persons, and neighborhood values; and further provided that the additional performance standards of Article VI and this article are complied with. Unless otherwise specified as a condition of approval, the height limits, yard spaces, lot area, and sign requirements shall be the same as for the uses in the district in which the conditional use is located.

A preliminary site plan complying with the requirements of Article XI shall accompany an application for approval of a conditional use, together with such information as may be required for a determination of the nature of the proposed use and its effect on the Comprehensive Plan, the neighborhood and surrounding properties. Procedures for approval of a conditional use, and approval and amendment of site plans, are contained in Article XI.

The conditional uses are as follows:

§ 225-5-2 R-2 Mixed Residential District (PS).

The Mixed Residential District (MRD) is designed primarily to accommodate single-family housing at medium densities, including attached units with appropriate design and buffering. On parcels of 10 acres or less, the housing type shall be low-density single-family detached on a lot of at least 10,500 square feet. On parcels over 10 acres, a mixed-use development is allowed subject to the requirements of § 225-5-2A(2) of this article. Special design requirements for this district are contained in Article VI of this chapter.

Mixed residential developments.

Mixed residential developments taking advantage of the following mixed housing type and mixed lot size provisions are permitted only on tracts over 10 acres located within an R-2 Zoning District.

Permitted types of residential uses within a qualifying mixed residential development include single-family detached dwellings, duplex dwellings, triplex dwellings, and townhouses. At least 50% of the total number of dwelling units must be single-family detached residences on lots of at least 10,500 square feet. No more than 40% of the total number of dwelling units may be single-family detached dwellings on lots of 9,500 square feet or greater or duplex dwellings on lots of 5,000 square feet or greater. No more than 10% of the total number of dwelling units may be triplex or townhouse residences on lots of 5,000 square feet or greater.

To the extent practicable, the duplex, triplex, and townhouse portions of a mixed-use development shall be developed more toward the interior rather than the periphery of the tract so that the single-family residences border adjacent properties.

Open space incentive.

The purpose of this incentive is to provide flexibility, consistent with the public health and safety and without increasing overall density, to the developer who subdivides property and constructs structures on the lots created in accordance with a unified and coherent plan of development.

This provision authorizes a developer to decrease lot sizes and leave the land "saved" by so doing as usable open space, thereby lowering development costs and increasing the amenity of the project without increasing the number of dwelling units beyond what would be permissible if the land were subdivided into the size of lots required by § 225-5-2A(2).

In any qualifying R-2 development, a developer may create lots that are smaller than those required in § 225-5-2A(2) if such developer complies with the following and if the lots so created are not smaller than the minimums set forth in the following table:

Dwelling Type	Minimum Lot Size Per Dwelling Unit (square feet)
Single-family	9,000
Duplex	4,500
Triplex	4,500
Townhouse	4,500

The amount of usable open space that must be set aside shall be determined by:

Subtracting from the standard square footage requirement set forth in § 225-5-2B(1) the amount of square footage of each lot that is smaller than that standard;

Adding together the results obtained in Subsection A(3)(d)[1] for each lot.

These provisions shall only be used if the usable open space set aside in a subdivision comprises at least 10,000 square feet of space that satisfies the definition of usable open space set forth in Article XIV. At least 50% of the required open space shall be contained as a single visually identifiable area exclusive of connecting corridors or pathways, and in no case be less than 50 feet in width nor 5,000 square feet in area.

The setback requirements of this district shall apply in a qualifying mixed-use development using smaller lot sizes.

Affordable housing incentive. To encourage the production of affordable housing, the maximum number of dwelling units permitted in any R-2 area may be increased by 10%, subject to the following:

At least 10% of the total dwelling units of the qualifying project must be rented or sold as affordable housing units.

The applicant shall guarantee that the minimum number of dwelling units proposed for eligibility will be made available for rent or sale pursuant to income, rental, and sales price guidelines certified by the Maryland Community Development Administration. The applicant shall cooperate with the Maryland, Community Development Administration to identify qualifying households.

The project is not otherwise subsidized by federal or state programs used to finance development or provision of affordable housing.

All affordable housing units shall be integrated into the overall design of the development and shall be intermixed throughout the development with exterior materials and appointments not differing from those of the other units in the project.

Developers of affordable housing shall be required to ensure that the dwelling units will continue to be available for rental or sale to persons of qualifying income levels for such minimum period of time as is set forth in any applicable program, or as may be required by the Town. Acceptable forms of assurance include provisions for acquisition of the units by a nonprofit or government housing agency, restriction on the resale of units, use of management agreements, or by other means acceptable to the Town.

When adding affordable housing dwelling units, a developer may create lots that are smaller than those required in the Table of Lot Area, Width, Height, and Yard Requirements for the R-2 District if the lots so created are not smaller than the minimums set forth in the following table:

Dwelling Type	Minimum Lot Size Per Dwelling Unit (square feet)
Single-family	9,000
Duplex	4,500
Triplex	4,500
Townhouse	4,500

Accessory uses (PS). Accessory structures and uses customarily incidental to any of the above uses are permitted by right. Certain uses are subject to performance standards (PS) which are specified in Article VI of this chapter.

Any accessory use permitted in the R-1 Low Density Residential District. Townhouses are not permitted to have accessory uses except community-owned swimming pools, pool houses including restrooms, and domestic storage in an accessory structure.

Conditional uses.

The purpose of these provisions is to provide for certain uses which cannot be well adjusted to their environment in particular locations with full protection offered to surrounding properties by rigid application of the District regulations. These uses are generally of a public or semipublic character and are essential and desirable for the general convenience and welfare but, because of the nature of the use, the importance of relationship to the Comprehensive Plan and the possible impact, not only on neighboring properties but on a large section of the Town, require the exercise of planning judgment on locations and site plans.

The conditional uses are as follows:

Cemeteries (PS).

Hospitals and sanitariums, but not animal hospitals.

Institutions, educational or philanthropic, including museums and art galleries.

Limited retail uses in MRD developments of 50 dwelling units or more at the rate of 2,400 square feet of floor area for every 50 dwelling units. If the development contains 101 or more dwelling units, then one acre of land for every 100 dwelling units may be used for limited convenience retail purposes (PS).

Public or governmental structures and uses, including schools, parks, parkways, playgrounds and public boat landings.

Public utilities or public service uses, structures, generating or treatment plants, pumping or regulator stations, substations and high voltage transmission lines (excluding multilegged structures).

§ 225-5-7 Mixed Commercial/Industrial District (PS).

Purpose.

The purpose of this district is to provide for comprehensively planned, multi-use developments of retail trade, commercial, service, industrial, and institutional activities. Special design requirements for this district are contained in Article VI of this chapter. All industrial uses in this district are subject to performance standards as specified in Article VI of this chapter.

To establish an appropriately mixed character within the entire District, the following percentages of floor area proposed in the District shall not exceed:

Retail trade/commercial/service: 60%.

Industrial: 65%.

Institutional: 15%.

If the land in the District is comprehensively planned and developed as a single unit without parcelization by subdivision, these individual percentages shall not be exceeded by more than 5% without approval of the Planning Commission upon application and for good cause shown.

If the land within the district is subdivided into smaller parcels and not comprehensively planned as a whole, the Zoning Administrator and the Planning Commission shall record the cummulative floor area of the various permitted uses as development of the district proceeds and shall assure compliance with the mixed-use percentage limits at full development of the district by restricting development of particular uses if it is apparent that the mixed-use percentage limits would be exceeded by their addition.

The minimum green area requirement, which shall include designated parks, pubic and private open space, active and passive recreational areas, for an MCI District development shall be not less than 20% of the total area devoted to MCI District uses, except that comparable amenities or facilities may be provided in lieu of green area if the Planning Commission determines that such amenities or facilities are sufficient to accomplish the purposes of the district, and would be more beneficial to the proposed development than strict adherence to the specific green area requirement. The minimum green area requirement shall apply unless a more restrictive regulation, e.g., the Critical Area or floodplain requirements, must be observed.

Development in this district shall be staged in such a manner as to coordinate development with the provision of public facilities, and such facilities shall be operational at acceptable service levels and capacities.

The number of entrances and exits from this district to Rt. 20 shall be limited and access to the individual uses within the district shall be provided through a system of internal roadways. The placement of individual uses along Rt. 20 each with its own ingress and egress to Rt. 20 shall not be allowed because of the resulting traffic difficulties.

§ 225-5-11 "O" Critical Area Overlay District.

The purpose of the Critical Area Overlay District ("O") is to implement zoning regulations and measures designed to protect and enhance water quality and habitat resources located within the Town's Critical Area. The geographic area for which the following District regulations apply shall be those lands and waters located 1,000 feet of the landward boundaries of all tidal waters, tidal wetlands and tributary streams in the Critical Area as designated on the Town of Rock Hall Critical Area Overlay District Maps. The intent of this district is to provide special regulatory protection for the resources located within the town Critical Area and to foster more sensitive development activity in shoreline areas. Another objective is to minimize adverse impacts to water quality and natural habitats.

Land use management district classifications.

Within the Town of Rock Hall Critical Area Overlay District ("O") there shall be three land use management area classifications: 1) Intensely Developed Areas (IDAs); 2) Limited Development Areas (LDAs); and 3) Resource Conservation Areas (RCAs) which shall be as shown on the Official Critical Area Maps.

These land use management areas correspond to the definitions established in the Chesapeake Bay Critical Area Criteria COMAR 14.15, as amended, for each area and specifically as identified on the Town of Rock Hall Critical Area maps, adopted as part of the Town's Critical Area Program. Mapped land use management area classifications are based on land uses established on or before 1 December, 1985, except for areas where the land classification may be changed by granting the Growth Allocation (GA) floating zone district classification. The following regulations shall be applied based on the specific land management classification.

Special density provisions.

Density in the Intensely Developed Areas (IDAs) shall be as established in the underlying base zone.

The density of development and minimum lot sizes permitted within a Limited Development Area (LDA) shall be governed by prescriptive densities within the applicable underlying base zoning districts. However, in underlying base zoning districts that permit residential use, density may not exceed 3.99 units per acre. Determination of density shall be based on the gross site area of the parcel prior to development or subdivision.

Residential densities in Resource Conservation Areas (RCAs) shall not exceed one dwelling unit per 20 acres regardless of densities permitted in applicable underlying base zones, except as provided below. Determination of density shall be based on the gross site area of the parcel, excluding tidal wetlands, except that in determining residential densities for a site, private wetlands may be included in the calculation on one dwelling unit per 20 density, provided the development density on the upland portion of the site doe not exceed one dwelling unit per eight acres.

Minimum lot sizes shall be governed by standards applicable to the underlying base zoning districts.

The one dwelling unit per 20 acre density limitation in the RCA shall not prevent a bona fide intrafamily transfer subjected to the following limitations:

Intrafamily transfer will be permitted on parcels of land in Rock Hall where it is shown that the parcel was recorded on or before March 1, 1986, and such parcel is at least seven acres and not more than 60 acres in size.

A bona fide intrafamily transfer shall be subject to all the requirements of the Town of Rock Hall Subdivision Regulations and a notation shall be placed on the final subdivision plan denoting the lot(s) that are created under these provisions.

Subdivision of land under the bona fide intrafamily transfer provisions contained herein shall be subject to the following limitations:

Parcels seven acres to less than 12 acres cannot be subdivided into more than a total of two lots.

Parcels 12 acres to less than 60 acres cannot be subdivided into more than three lots.

A lot created pursuant to these provisions may not be subsequently conveyed to any person except as provided herein:

Where the conveyance is to a member of the owner's immediate family; or

Where the conveyance of the lot is as part of a default on a mortgage or deed of trust.

Lots created pursuant to these provisions shall not be created for purposes of ultimate commercial sale. In addition, any lot created under this section may not be transferred or sold to a third party, not a member of the owner's immediate family or holder of a mortgage or deed of trust on the property, unless and until the Planning Commission has determined that the following can be conclusively proved:

A change in circumstances has occurred since the original transfer, not of the owner's own doing, which would warrant permitting a subsequent transfer when such circumstances are consistent with the warrants and exceptions contained herein; or

Other circumstances necessary to maintain land areas to support protective uses of agriculture, forestry, open space, and natural habitats in RCAs warrant an exception.

Deeds of transfer shall include the provisions contained in Subsection B(5)(e) above as covenants which shall restrict the subsequent transfer or sale of a lot or lots created pursuant to the intrafamily transfer provisions contained herein to a third party, not a member of the owner's immediate family or holder of a mortgage or deed of trust on the property.

General regulations.

Except as provided in § 225-5-11J, Buffer exemption area provisions, permitted uses, accessory uses and special exception uses shall be limited to those permitted within the existing applicable underlying base zoning district, as shown on the Official Rock Hall Zoning Maps.

Existing industrial and commercial facilities, including aquaculture facilities, shall be allowed in the RCA. However, additional land may not be zoned for industrial or commercial development in the RCA.

To prevent trees from falling and blocking streams, causing damage to dwellings or other structures, or resulting in accelerated erosion of the shore or streambank;

In conjunction with horticultural practices used to maintain the health of individual trees;

To provide access to private piers;

To install or construct an approved shore erosion protection device to measure; or

To protect forests from extensive pest or disease infestation or threat from fires if approved by the Department of Agriculture or the Bay Watershed Forester.

Development standards in intensely developed areas (IDAs).

All development and redevelopment in IDA shall be subject to the following development standards and/or conditions, in addition to those established in other sections of this chapter, except that development on lots qualifying under Article X, § 225-10-9 must only comply with these provisions insofar as possible as determined by the Planning Commission:

All sites for which development activities are proposed, and which require subdivision approval or site plan review and approval, shall identify environmental or natural features on that portion of site within the Critical Area;

No structure or uses associated with development in an Intensely Developed Area shall be permitted within the Buffer, except for water-dependent facilities, unless the site is within a Buffer Exemption Area;

Development and redevelopment shall be subject to the Habitat Protection guidelines in the Rock Hall Critical Area Program;

Development and redevelopment shall be required to install stormwater management practices appropriate to site development which achieve a ten-percent reduction of pre-development pollutant loadings unless the Mayor and Council permit offsets as per the Rock Hall Critical Area Program;

Development and redevelopment projects shall delineate those site areas not covered by impervious surfaces that are to be maintained or established in vegetation.

Where vegetation is not proposed, the developer shall demonstrate why plantings for such portions of the site are impracticable. The types of planting and vegetation proposed shall be in accordance with guidelines established in Subsection G below;

A minimum twenty-five-foot Buffer shall be maintained around all non-tidal wetlands as identified in the Rock Hall Critical Area Program where development activities or other activities which may disturb the wetlands or wildlife contained therein shall be prohibited unless it can be shown that these activities will not adversely affect the wetland; and

Development and redevelopment projects that propose shore erosion protection must demonstrate that significant shore erosion is occurring on the site.

Development and redevelopment projects shall install vegetative shore erosion control measures (where feasible and where appropriate) on portions of the site proposed for development and near such portions if the shore erosion threatens the proposed development portion. Where control of shore erosion cannot be accomplished by vegetative measures and structural measures are required, proposed development must either:

Construct appropriate structural measures to control shore-line erosion on sites proposed for development consistent with the policies established in the Shore-line Erosion Protection Section of the Rock Hall Critical Area Program; or

Set back the development behind the Buffer based on the annual shore erosion rate. To determine the setback, published data on annual erosion rates for the site must be used. (If two or more published rates are available, the highest rate must be used.) If published data are not available, either the annual rate is assumed to be two feet per year or the developer shall do a technical study to determine the annual erosion rate. The setback shall be the annual erosion rate times 25 years.

Development standards in limited development areas (LDAs) and Resource Conservation Areas (RCAs).

Development and redevelopment in an area designated Limited Development (LDA) or Resource Conservation (RCA) shall be subject to the following standards, except that development on lots of record qualifying under Article X, § 225-10-9 must comply with these regulations insofar as possible as determined by the Planning Commission:

Site development shall be designed to assure that those features or resources identified as Habitat Protection Areas are afforded protection as prescribed in the habitat protection element of Town of Rock Hall Critical Area Program;

Roads, bridges and utilities serving development shall be so located as to avoid disturbances to habitat protection areas. When no alternative exists and such infrastructure must cross or be located in Habitat Protection Areas, the developer shall demonstrate how impacts to habitats have been minimized and that no feasible alternative location of such infrastructure exists;

All development activities which cross, or are located adjacent to, tributary streams in the Critical Area shall:

Not be located in the Buffer but be designed in a manner to reduce increases in flood frequency and severity;

Provided for the retention of natural streambed substrate;

Minimized adverse impacts to water quality and stormwater runoff; and

Retain the existing tree canopy.

Development activities shall be located and designed to provide for the maintenance of the wildlife and plant habitats on the existing site and to maintain continuity with those on adjacent sites. When wildlife corridors exist or are proposed they shall include any existing Habitat Protection Areas and connect large forested areas on or adjacent to the site.

Forest and development woodlands, as defined by the Town Critical Area Program, shall be created or protected in accordance with the following;

When no forest exists on the site, at least 15% of the gross site area shall be afforested in accordance with a plan approved by the Bay Forester. The location of the afforested areas should be designed to reinforce protection to habitats on the site or to provide connections between forested areas when they are present on adjacent sites;

When forests or developed woodland exist on the site and proposed development requires the cutting or clearing of trees, areas proposed for clearing shall be identified on the proposed development plan (the developer shall submit plans for development and areas to be cleared to the Maryland Forest, Park and Wildlife service for comments and recommendations and shall transmit the comments to the Planning Commission). A grading permit must be obtained prior to any clearing or cutting associated with proposed development and in addition, cutting or clearing which is associated with development shall be subject to the following limits and replacement conditions.

All forests cleared or developed shall be replaced on not less than an equal area basis on the site or on an alternative site approved by the Planning Commission as per § 225-5-11F(3)(b)[7] below. When the development pad is strictly limited to the minimum required, and cleared areas are reforested to the extent possible a forest area shall continue to be considered a developed woodland and no replacement shall be required;

No more than 20% of the forested or developed woodland within the site proposed for development may be removed (except as provided for in the requirement below) and the remaining 80% shall be maintained as forest cover through the use of appropriate instruments (e.g., recorded restrictive covenants). Removal of forest or developed woodland cover in the Buffer is prohibited;

The clearing of forest or developed woodlands up to 20% shall be replaced on an area basis of one to one; a developer may propose clearing up to 30% of the forest or developed woodland on a site, but the trees removed in excess of 20% must be replaced at the rate of 1.5 times the area removed;

If more than 30% of the forest on a site is cleared, the forest is required to be replanted at three times the total area extent of the cleared forest;

If the cutting of forests occurs before a grading permit is obtained, the forest is required to be replanted according to the above requirement;

Surety in the form of a letter of credit acceptable to the Town Attorney shall be provided in an amount suitable to assure forest replacement as required; and replacement shall be guaranteed for two growing seasons at which time the letter of credit shall be released;

The forests and developed woodlands required to be retained or created through afforestation shall be maintained through restrictive covenants, easements, or similar instruments in a form approved by the Town Attorney.

Development or slopes greater than 15% shall be prohibited unless such development is demonstrated to be the only effective way to maintain or improve slope stability;

Except as otherwise provided in this subsection for stormwater run-off, man-made impervious surfaces are limited to 15% of a parcel or lot.

If a parcel of lot 1/2 acre or less in size was in residential use or zoned for residential purposes on or before December 1, 1985, then man-made impervious surfaces associated with that use are limited to 25% of the parcel or lot.

If a parcel or lot 1/4 acre or less in size was in nonresidential use on or before December 1, 1985, then man-made impervious surfaces with that development are limited to 25% of the parcel or lot.

If an individual lot one acre or less in size is part of a subdivision approved after December 1, 1985, then man-made impervious surfaces of the lot may not exceed 25% of the lot. However, the total of the impervious surfaces over the entire subdivision may not exceed 15%.

This subsection does not apply to a trailer park that was in residential use on or before December 1, 1985.

Appropriate structural measures to control shoreline erosion on sites proposed for development shall be constructed consistent with the policies established in the Shore Erosion Protection Section of the Rock Hall Critical Area Program; or

The development shall be set back behind the Buffer based on the annual shore erosion rate. To determine the setback, published data on annual erosion rates for the site must be used. (If two or more published rates are available, the highest rate must be used.) If published data are not available, either the annual rate is assumed to be two feet per year or the developer shall do a technical study to determine the annual erosion rate. The setback shall be the annual erosion rate times 25 years.

Woodland reforestation and afforestation standards.

Where reforestation or aforestation is required the following minimum standards shall be used within the Critical Area District:

The replacement or establishment of forests or developed woodlands shall assure a diversified plant community, but may include other types of tree plantings where necessary to correct an existing soil stabilization problem. Diverse forest plantings shall include a canopy layer and a shrub layer.

For each acre of land where woodlands must be replaced or established, plantings shall consist of trees and/or wildlife shrub species spaced approximately at eight-foot intervals in rows eight feet apart, or other suitable spacing as determined by the Bay Watershed Forester on a site-by-site basis, which result in a minimum of 300 stems per acre after the first growing season.

Planting plans, letters of credit and inspections. Required planting plans shall be prepared and submitted with the site plan or preliminary and final subdivision plat. A planting plan shall be included as a required public improvement with site plans or subdivisions plats. The planting plan must demonstrate compliance with the minimum standards for reforestation and afforestation specified above. It is required that the planting plan shall be prepared by a professional registered forester, landscape architect, or an experienced landscape designer. The planting plan shall show:

The site plan, structure outlines (remaining and proposed), walls, fences, parking spaces, loading spaces, driveways, walks, storage areas, public rights-of-way, easements and the general location of structures and uses of abutting properties;

Existing and proposed grades;

Existing vegetative cover to be retained and the location, general size and type of such vegetation;

The methods for protecting plant materials after construction;

A plant schedule and plan listing plants to be used giving their botanical and common names, size at time of planting, and quality of each;

An indication of whether plants are balled and burlapped, container grown or bare root; and

An indication of the spacing and location of all proposed trees, shrubs and ground covers.

Substitution of plants; time of planting.

Although plant types should be chosen from the recommended plant list available from the Planning Commission or the Maryland State Bay Watershed Forester, plant types that vary from this list may be substituted with the approval of the Local Bay Watershed Forester. Plants for afforestation or reforestation shall be approved by the Bay Watershed Forester for suitability in regard to the eventual size and spread, susceptibility to diseases and pets, and adaptability to existing soil and climate conditions.

All planting should be done in the months of March and April of each year. For the first two years steps should be taken to control competing vegetation. Technical assistance from the State's Bay Watershed Forester is highly recommended.

The planting plan shall be accompanied by an estimate of the installation cost for all afforestation and reforestation. Upon approval of the plan and cost estimate, the developer or owner shall enter into an agreement with the Town of Rock Hall to provide plantings as required. The agreement shall be in form and substance as approved by the Town and shall be accompanied by a letter of credit executed by the owner or developer in the amount of 120% of proposed plant materials, labor and maintenance costs.

If all afforestation or reforestation is not completed within two years after the first spring planting date following recordation, or if the requirements set forth in the approved planting plan are not met, the letter of credit shall be forfeited and payment in full to the Town shall be ordered. The funds so received shall be used by the Town to defray the cost of providing the approved Buffer afforestation or reforestation for the site.

If the foregoing costs exceed the amount of the letter of credit, the excess shall be a continuing obligation of the property owner.

All letters of credit shall be in a form acceptable to and approved by the Mayor and Council.

All security posted will be held for a period two years after installation of the planting, to assure the proper maintenance and growth. Failure to maintain or replace the dead portions of the planting shall result in a forfeiture of the surety posted to the extent necessary to replace the dead plant materials.

The Mayor and Council or their designee may from time to time release those portions of the surety which may be appropriate.

Where existing vegetation is to be used to meet the requirements contained herein, the surety requirement may be modified appropriately. However, to the extent that existing vegetation is or will be inadequate to meet the standards set herein, a planting plan meeting all of the requirements herein must be submitted.

All plantings shall be inspected by the Town or the Bay Watershed Forester upon notification by the developer or owner and shall be approved according to the following standards:

The planting shall adhere to the approved plan. Substitutions or revisions may be made with the approval of the Bay Watershed Forester or the Planning Commission.

All plants shall be protected from vehicular encroachment by wheelstops, curbs or other barriers unless distance provides adequate protection.

No planting shall result in vegetative growth exceeding 36 inches in height, within 30 feet of any street intersection or otherwise obstruct sight-lines.

Special provisions for water-dependent facilities.

All applications for development of commercial marinas or other water-related uses in the Critical Area must include the following information:

Water depth contours shown at two-foot intervals at mean low water taken by sounding (unless otherwise specified by the Town Planning Commission).

Existing and proposed regraded surface of the land.

Location and dimensions of all boat launching ramps.

Location and dimensions of all boat slips and mooring buoys.

Location of fuel dock and gasoline storage tanks.

Location of all required buffer/yards/structure restriction lines.

Applications for water-dependent use shall be accompanied by an environmental assessment report which indicates how the proposed project achieves the following criteria:

That the activities will not significantly alter existing water circulation patterns or salinity regimes;

That the water body upon which these activities are proposed has adequate flushing characteristics at the site;

That disturbance to wetlands, submerged aquatic plant beds, or other areas of important aquatic habitats will be minimized;

That adverse impacts to water quality that may occur as a result of these activities, such as non-point source run-off, sewerage discharge from land activities or vessels or from boat cleaning and maintenance operations, is minimized;

That shellfish beds will not be disturbed or be made subject to discharge that will render them unsuitable for harvesting;

That dredging shall be conducted in a manner, and using a method, which causes the least disturbance to water quality and aquatic and terrestrial habitats in the area immediately surrounding the dredging operation or within the Critical Area.

That dredged spoil, except for clean sand for beach nourishment, will not be placed within the Buffer or elsewhere in that portion of the Critical Area which has been designated as a Habitat Protection Area;

That interference with the natural transport of sand will be minimized; and

That no disturbances will occur to aquatic areas of historic waterfowl staging and concentration areas.

Special Buffer requirements.

The following special yard requirements shall apply within the Critical Area Overlay District ("O"):

Except as provided for water-dependent facilities in § 225-5-11D, new development activities, including structures, roads, parking areas, impervious surfaces, and septic systems are not permitted in the Buffer.

The Buffer shall be expanded to include contiguous sensitive areas on the parcel whose development or disturbance may impact streams, wetlands, or other aquatic environments. This expansion will occur whenever new land development or other land disturbing activities, such as clearing natural vegetation for agriculture or mining, are proposed. The expanded Buffer must be shown on plans required for such development.

Sensitive areas have the following features: 1) hydric soils and soils with hydric properties as designated by the Soil Conservation Service; 2) high erodable soils with a K value greater than 0.35; and 3) steep slopes greater than 15%. The Buffer shall be expanded according to the following rules:

When the site of the proposed land disturbance drains to a slope greater than 15% contiguous to the Buffer, the Buffer shall be expanded four feet for every percent of slope over 15% or to the top of the slope, whichever is greater, but in no case more than 10 feet beyond the top of the slope greater than 15%.

Buffer shall be expanded to the upland limit of adjacent hydric soils, soils with hydric properties, and eroible soils, within the Critical Area, whichever is less. The Buffer will be expanded to include those soils lying in the drainage area between the proposed land disturbance and the Buffer.

Buffer Exemption Area provisions. The following special provisions apply in the Buffer Exemption Areas in the IDA, LDA, or RCA.

Permitted uses:

New development or redevelopment consistent with the provisions of § 225-5-11 of this article provided that the Development and Redevelopment Rules and Offsetting Requirements set forth below are observed.

Shore erosion protection measures provided that such measures are consisten with the Town's shore erosion protection policies and provided that the measure has obtained all applicable state and federal permits.

No cutting or clearing of trees or natural vegetation is permitted in the Buffer except that limited cutting or clearing of trees under an approved forest management plan for the following purposes only:

For personal use providing that Buffer functions are not impaired and trees cut are replaced.

To prevent trees from falling and blocking streams, causing damage to dwellings or other structures, or resulting in accelerated erosion of the shore or stream-bank;

In conjunction with horticultural practices used to maintain the health of individual trees;

To provide access to private piers;

To install or construct an approved shore erosion protection device or measure;

To protect trees from extensive pest or disease infestation; or

To permit the development or redevelopment allowed above to be constructed or installed.

Prohibited uses:

Water polluting activities including, but not limited to, storage of vehicles, fuel or chemicals.

Development and redevelopment rules:

Existing structures. The expansion or redevelopment of existing structures in the Buffer Exemption Area may not increase impervious surfaces shoreward of the existing structure and shall not result in greater than a twenty-five-percent increase in the total site area in impervious surfaces, as described below.

Removal of existing structures. When a structure within the Buffer Exemption Area is removed or destroyed, it may be replaced, insofar as possible, no closer than 100 feet from the edge of tidal waters, tidal wetlands or tributary streams. In such cases where a setback line exists as defined by structures on adjacent lots or parcels, the structure may not be replaced shoreward of that line. Any impervious surfaces created greater in extent to preexisting impervious surfaces within the Buffer Exemption Area shall be offset as described below.

New development. New development in the Buffer Exemption Area shall minimize the shoreward extent of impervious surfaces insofar as possible taking into consideration existing Town yard setback requirements and other such factors. In no case may such impervious surfaces be extended shoreward of any setback line as defined by existing structures on adjacent lots or parcels.

Offsetting requirements. New development or redevelopment in the Buffer Exemption Area which causes impervious surfaces as described above shall be required to offset for such development as follows:

The extent of the lot or parcel shoreward of the new development or redevelopment shall be required to remain, or shall be established and maintained, in natural and native vegetation; and

Natural and native vegetation of an area twice the extent of the impervious surface created in the Buffer Exemption Area shall be planted in a Buffer Exemption offset Area or other location as may be determined by the Town. The Town may collect fees in lieu of such planting.

§ 225-5-12 GA Growth Allocation District.

The GA Growth Allocation District is not mapped but is hereby designated for use within the Critical Area District on lands classified as Resource Conservation Areas (RCA) and/or Limited Development Areas (LDA). The purpose of the GA District is to designate areas of the Critical Area District where the Mayor and Council have approved a change in the current land management classification on specific sites and for specific development projects so that they may be developed to the extent permitted by this chapter and the new land use management classification. Only specific development projects, the site plan or preliminary subdivision plat for which has been approved by the Planning Commission, shall be approved for the GA Growth Allocation District classification and thereby receive Critical Area Growth Allocation.

Location criteria. The granting of the GA Growth Allocation District classification shall be consistent with the Town of Rock Hall Critical Area Program. When approving the GA Growth Allocation District the Mayor and Council shall use the following guidelines to determine if the location of the proposed land management classification under the GA District classification is consistent with the Town of Rock Hall Critical Area Program:

New IDA will be located in existing LDA or adjacent to existing IDA;

New LDA will be located adjacent to existing LDA or IDA;

To the extent possible no more than half of the growth allocated will be located in RCA adjacent to LDA or IDA;

If the Town is unable to utilize any portion of the growth allocation within or adjacent to existing IDA or LDA, that portion of the growth allocation which cannot be so sited may be located in the RCA;

New IDA and LDA will be located in order to minimize impacts to Habitat Protection Areas and in a manner that optimize benefits to water quality;

New IDA or LDA located in the RCA will conform to all criteria of the Town of Rock Hall Critical Area Program for such areas; and

When growth allocation is permitted in RCA not adjacent to IDA or LDA, the developer will be required to cluster the development and provide for resource enhancement in the design of such development.

Conditions of approval.

Projects approved for the GA Growth Allocation District shall be substantially completed within three years of the date of approval. If after three years the project is not completed, the GA Growth Allocation Floating Zone District classification shall be withdrawn.

The Planning Commission shall determine whether a project is substantially completed or not. Substantially completed projects are defined as projects in which all public improvements, such as roads, community or shared sewer and/or water facilities, etc., have been built, as required by the Town or state and the lots or units are being actively marketed.

The development of a proposed project must demonstrate that the following design standards will be met or exceeded in order to be approved:

All applicable requirements of the Town of Rock Hall Critical Area Program, the Zoning Ordinance and the Subdivision regulations.

Limit the area of disturbance for nonresidential development to no more than 60% of the total site area.

The design of the development enhances the water quality and resource and habitat values of the area, e.g., results in additional planting of forest cover in the Buffer or implementation of best management practices on portions of the site to be retained in agriculture use.

The development incorporates the comments and recommendations of the Town and the Maryland Forest, Park and Wildlife Service in the project design.

The developer executes restrictive covenants that guarantee maintenance of the required open space areas.

Computing the use of the growth allocation.

The manner in which growth allocation for a proposed project will be subtracted from the total Town growth allocation will be based on the area of disturbance.

Disturbed areas are defined as those portions of the development site which either do not remain in natural vegetative cover or are not revegetated after the development is completed.

In order to determine the area of disturbance, the Town will compute the total area of structure coverage and other impervious surfaces. The total of these computations will be subtracted from the Town growth allocation.

Process.

The Town's growth allocation will be used on a project-by-project basis to permit densities that are consistent with the Comprehensive Plan, the Critical Area Program, and the existing zoning when a specific development project is proposed. The following procedures will be followed in determining if a site qualifies for growth allocation.

Applicants for growth allocation will request that the Mayor and Council assign growth allocation to their project site.

All applications for the Growth Allocation District Classification shall be accompanied by a project site plan, or subdivision plat prepared as per the requirements of the Town of Rock Hall Zoning Ordinance or Subdivision Regulations.

The Town staff will review concept, sketch, or comprehensive development plans submitted for consistency with the Critical Area Program and will provide technical comments and recommendations to the applicant prior to submission of preliminary site plans or plats.

Permitted development density or intensity will be determined at this time, subject to the applicant obtaining approvals from local, state and federal authorities for such things as sewer, water, access, dredging permits, and forest management plans.

After the applicant has incorporated the staff's recommendations and obtained all necessary approvals, a preliminary site plan or subdivision plat may be submitted for growth allocation.

Before being considered for growth allocation by the Mayor and Council all applicants will be required to obtain all local, state and federal comments, recommendations, approvals and permits required.

Following the staff review of the revised submission, and after the applicant has addressed the recommendations of the staff's, the growth allocation application will be reviewed by the Town of Rock Hall Planning Commission.

A hearing to permit the public an opportunity to comment on the proposed use of the Town's growth allotment will be conducted by the Planning Commission prior to making a recommendation to the Mayor and Council.

Applications for growth allocation will be forwarded to the Critical Area Commission for approval after the Mayor and Council has made their recommendations.

A final public hearing on the application for growth allocation and so amending the Critical Area Program will be held by the Mayor and Council.

If the growth allocation is tentatively approved by the Mayor and Council, the application is forwarded to the Critical Areas Commission for action and/or approval.

In approving an application for growth allocation, the Mayor and Council may establish conditions of approval that are consistent with the intent of the Town's Critical Area Program.

Following approval by the Mayor and Council and the Critical Area Commission, the applicant may proceed to the preparation of the final site plan or subdivision plat.

Prior to approving the final site plan or subdivision plat, the Planning Commission will ensure that all conditions of approval are incorporated into the final plan, public works agreement, deed covenants, etc.

Final subdivision plats and site plans shall be processed as per the requirements of the Town of Rock Hall Zoning Ordinance and Subdivision Regulations.

Recording the GA Growth Allocation District.

The Official Critical Area Map(s) will be amended to reflect the new "GA" District classification along with a notation of the new land management classification.

Successful projects granted the "GA" District classification will be submitted for final site plan or final subdivision approval as per the requirements of the Zoning and/or Subdivision Regulations and shall delineate the Growth Allocation District on the record plat or site plan.

Process.

Applicants for growth allocation will request that the Mayor and Council assign growth allocation to their project site.

After the applicant has incorporated the staff's recommendations and obtained all necessary approvals, a preliminary site plan or subdivision plat may be submitted for growth allocation.

Applications for growth allocation will be forwarded to the Critical Area Commission for approval after the Mayor and Council has made their recommendations.

A final public hearing on the application for growth allocation and so amending the Critical Area Program will be held by the Mayor and Council.

If the growth allocation is tentatively approved by the Mayor and Council, the application is forwarded to the Critical Areas Commission for action and/or approval.

In approving an application for growth allocation, the Mayor and Council may establish conditions of approval that are consistent with the intent of the Town's Critical Area Program.

Following approval by the Mayor and Council and the Critical Area Commission, the applicant may proceed to the preparation of the final site plan or subdivision plat.

Final subdivision plats and site plans shall be processed as per the requirements of the Town of Rock Hall Zoning Ordinance and Subdivision Regulations.

Recording the GA Growth Allocation District.
