[Amended 5-7-2007 by Ord. No. 2007-13]
The standards of construction, architecture and design herein contained are intended only as minimum requirements. The Town, through planning staff or the Planning Commission, may require additional specific site configuration and design elements that may include site layout, architectural, style, streetscape, lighting and other aspects in order to achieve compatibility with the character of the surrounding area and vicinity, and carry out the intent of this Code to assure a high-quality, pleasant, sustainable and durable neighborhood. All development, including commercial, residential and industrial (including infill and redevelopment) shall conform to the Town Comprehensive Master Plan.
[Added 10-6-2008 by Ord. No. 2008-04]
The Town of Mount Airy hereby adopts Chapter
103, Development and Subdivision of Land, Article
IV, Environmental Site Delineation (§§ 103-12, 103-13 and 103-14), of the Carroll County Code and all amendments thereto to be effective within the limits of the Town of Mount Airy and enforceable in accordance with the provisions thereof, except that once plans or permits are approved, new environmental site delineation approval is not required if construction begins within nine years. Whenever Chapter
103, Article
IV, of the Carroll County Code refers to "the County," these words shall be construed to refer to the Town of Mount Airy whenever such construction would be reasonable.
Building lines along each street shall be drawn on the plat, and side and rear building lines noted as required by zoning regulations. The locations of these lines shall be clearly indicated by dimensions.
Whenever the area is divided into lots larger than ordinarily used in the area for building purposes, and there is reason to believe that such lots will eventually be resubdivided into smaller building lots, consideration shall be given to the street and lot arrangement of the original subdivision so that additional minor streets can be opened which will permit a logical arrangement of smaller lots. Easements or deeds providing for the present or future opening and extension of such streets, may, at the discretion of the Town Planning Commission, be made a condition of the approval of the plat.
Where a proposed park, playground, school or other public use shown on the Comprehensive Master Plan for Mount Airy is located in whole or in part in a subdivision, such sites shall be indicated on the subdivision plat. School, park and other public sites other than the reserve recreation area required pursuant to §
98-23 of these regulations are to be reserved and negotiated within one year of the recording date of the subdivision.
[Amended 5-3-2010 by Ord. No. 2010-2]
A. For the purposes of this section, the following terms have the following meanings:
BASE DENSITY The original density permitted under the property's residential zoning category (dwelling units per acre).
COMMUNITY OPEN SPACE The area of open space remaining after natural open space has been designated. The area may be used for passive or active recreation and must be suitable for dry ground activity. Central parks and tot-lots are encouraged.
ENVIRONMENTAL RESOURCE AREA The area of a site that includes wetlands and submerged areas, slopes of 25% or more and the historical floodplain. These areas are considered unbuildable land.
GREEN SPACE Open space maintained in a natural, undisturbed or revegetated condition, but could or should include a walk path or bike path to encourage connectivity and promote an added benefit throughout.
HISTORICAL FLOODPLAIN That area which, assuming ultimate development of its watershed based on current zoning, would be inundated by water runoff from the one-hundred-year storm.
IMPERVIOUS COVER Any surface in the urban/suburban landscape that cannot effectively absorb or infiltrate rainfall.
LOT WIDTH The width of a housing lot (in feet) that fronts along the street.
NATURAL CONDITION The topography and vegetation of an area that is unaltered by clearing and grading during construction and protected in perpetuity.
NET DEVELOPABLE ACREAGE The result of subtracting the environmental resource area and any recreation area dedicated in accordance with §
98-23 of Chapter
98, Subdivision of Land and Site Plan Review, from the gross developable acreage.
OPEN SPACE A portion of a development site that is permanently set aside for public or private use and will not be developed. Open space may be community open space or green space. However, open space does not mean land considered unbuildable, existing rights-of-way and utility easements, setbacks and lawns, stormwater management (unless unique forms are used that preserve the area in a natural or forested condition) or roads and parking areas.
OPEN SPACE DEVELOPMENT A development pattern that arranges the layout of buildings in a compact area of the sites to reserve a portion of the site for community open space or green space that is protected in perpetuity.
OPEN SPACE EASEMENT An easement conveyed by the owner of real property to the Town protecting open space from future development and environmental damage by restricting future construction of any improvements to those improvements expressly reserved in the easement and/or restricting removal of soil, trees, other vegetation or other natural features of the property except as is consistent with conservation, recreation or agricultural uses in order to preserve and protect the open space and natural condition of the property in perpetuity.
RIGHT-OF-WAY The width of a public roadway that encompasses the pavement width and/or land needed for placement of sidewalks, utilities and storm drainage.
SETBACK AREA The area between the street right-of-way line or lot line and setback lines within which no principal structures shall be erected or placed.
SETBACK LINE The line that is the required minimum distance from the street right-of-way line or any other lot line that establishes the area within which no principal structure shall be erected or placed.
STREAM BUFFER A vegetated area bordering a stream which exists or is established to protect a stream system. Alteration of this vegetated area is strictly limited.
B. Open space development shall be required in the Town of Mount Airy and shall apply, along with the provisions of this section, to all residential zones, the Mixed Use District (MXD), or special exception residential uses in commercial zones, and any development with a residential component located in the Downtown Zone (DTZ) in accordance with the requirements set forth in this Code applicable thereto, except that plats recorded before the adoption of this section are exempt from the provisions of this section.
[Amended 2-3-2020 by Ord. No. 2019-12; 8-3-2020 by Ord. No. 2020-01; 11-6-2023 by Ord. No. 2023-32]
C. All concept plans, preliminary plans, final plans and record plats shall set forth and clearly delineate:
(1) The total gross area of the lot or parcel;
(2) Environmental resource area;
(4) The boundaries of designated open space;
(6) Stormwater management facilities; and
D. Open space shall be marked in the field with signage approved by the Planning Commission to distinguish it from private property.
E. A percentage of open space must be reserved as detailed in this section and is generally based on housing density. The denser a development is, the greater the amount of open space required will be. However, when the Planning Commission determines it appropriate, it shall recommend to the Town Council that such development shall be required to pay a fee in lieu of dedication of land. The Council, in such case, shall request the recommendation of the Board of Recreation and Parks. Any such fee shall be equal to the value of the land which otherwise would be required to be dedicated (based upon the average appraisal value of the site at its new or current zoning, whichever is higher) based upon any bona fide sale of the land to be developed that occurred within 12 months prior to preliminary subdivision approval or if there is no such sale, determined by an appraiser selected and paid for by the Town and reimbursed by the developer and approved by the Town Council. The fee shall be used for recreational purposes in the Town's park system and shall be paid prior to recording the final plat. The Planning Commission and the Board of Recreation and Parks shall make their recommendations, in writing, regarding the proposed open space, or fee in lieu thereof, and the final decision in each case shall be made by the Town Council.
[Amended 2-3-2020 by Ord. No. 2019-12]
F. At least 50% of designated open space shall be designated as green space and shall be maintained in a natural, undisturbed condition. The remaining percentage may be used/improved as community open space for dry ground activity. Centralized open space areas with the lots are encouraged.
G. Open space requirements for proposed developments to which this section is applicable shall be as follows:
[Amended 2-3-2020 by Ord. No. 2019-12]
(1) Except as set forth in Subsection
G(2) below, the total number of residential units allowable within an open space development shall not exceed the number of units that would otherwise be allowed in the existing zoning district using conventional development. The total number of units allowed shall be determined using the following formula:
T = BD*[A – (U+R)] |
Where: |
| T | = | Total units (dwelling units) |
| BD | = | Base density (dwelling units/acre) |
| A | = | Total site area (acres) |
| U | = | Unbuildable land as defined in Section II (acres) |
| R | = | Road and utility right-of-way (acres) |
(2) Only for developments located in the Downtown Zone (DTZ) with lots less than or equal to 15,000 square feet, the parks and open space requirement will be fully exempted.
(3) Developments with a residential component located in the Downtown Zone (DTZ) with lots greater than 15,000 square feet in accordance with the requirements set forth in this Code applicable thereto shall provide open space as follows:
POS - Parks and open space required to be dedicated to the Town of Mount Airy, in acres |
TA - Total gross acres of parcel |
P - Projected number of resident persons added |
CSF - Total gross commercial space in square feet being provided |
(a) Where providing three acres of parks and open space per 100 persons would equate to less than or equal to 5% of the total gross parcel acreage of the proposed development, then the development must provide the pro-rata share of three acres per 100 persons; or
(b) Where providing three acres of parks and open space per 100 persons would equate to more than 5% of the total gross parcel acreage of the proposed development, then the development must provide the pro-rata share of three acres per 100 persons less one person for every 200 square feet of commercial space provided in the proposed development project, or 5% of the gross parcel acreage, whichever is greater, in order to qualify for the exemption:
H. Except for developments with a residential component located in the Downtown Zone (DTZ) in accordance with the requirements set forth in this Code applicable thereto, lot width, rear, front and side yard setbacks may be reduced to 25% of the requirements in the base zoning, subject to the following rules:
[Amended 2-3-2020 by Ord. No. 2019-12]
(1) Lot size may be reduced to 25% of base density but no smaller than 1/8 of an acre;
(2) Conservation zoned lots may be reduced up to 75%; and
(3) R-1 zoned lots may be reduced by 50%.
I. Except for developments with a residential component located in the Downtown Zone (DTZ), the total area of dedicated open space shall equal the amount by which all dwelling unit lots are reduced below the base zoning and shall meet the requirements outlined in Table 1 below.
[Amended 2-3-2020 by Ord. No. 2019-12; 8-3-2020 by Ord. No. 2020-01; 11-6-2023 by Ord. No. 2023-32]
Table 1: Open Space Required For Various Densities |

Conservation/R-1 | 25% |
R-2/RE | 35% |
R-3 – R-5 | 45% |
R-5 – R-7 | 50% |
MXU-CC | 30% |
MXD | 30% |
(1) A request for the adjustment of the above percentages can be made to the Planning Commission based upon any unique features of the parcel. The Planning Commission, in its discretion, may grant a reduction to the percentages set forth in Table 1 above if it is established by the applicant/developer that the adjustment will be more beneficial to the needs of the community for that specific parcel. In determining whether to grant such an adjustment, the Planning Commission may seek input from the Board of Parks and Recreation or from any other source that the Planning Commission deems beneficial.
J. The following activities or land uses shall not be counted as a part of designated open space:
(1) Land considered unbuildable;
(2) Existing rights-of-way and utility easements;
(4) Stormwater management (unless unique forms are used that preserve the area in a natural or forested condition); or

(2) The conveyance contains appropriate provision for proper reverter or retransfer in the event that the organization becomes unwilling or unable to continue carrying out its functions;
(3) A maintenance agreement acceptable to the homeowners' association is entered into by the developer and the organization; and
(4) Open space that is within property governed by any homeowners' association, condominium association, planned unit development association or other similar entity shall be open to the public.
P. Any person or entity responsible for the maintenance or management of open space shall assure that the open space will be protected in perpetuity from all forms of development, except as shown on an approved development plan, and that it will never be changed to another use and shall:
(1) Prescribe all allowable and unallowable uses and activities within such open space;
(2) Provide detailed standards and schedules for maintenance of the open space, including vegetative management; and
