5-1.01 Purpose

A. In general, the purpose of setbacks is to ensure that the use of a property does not infringe on the rights of neighbors, to allow room for lawns and trees, for light and sunshine in the home, for space for recreation outside the home, and to serve as filtration areas for storm water run-off.

In the Rural District, dwelling setbacks are also needed to provide a buffer from permitted agricultural uses, such as raising animals, and to provide privacy for those desiring a more rural atmosphere.

Front Yards: Adequate front yards reduce the noise and dust that can reach a home. Within a district, relatively uniform setbacks are needed to prevent structures from obstructing views on adjoining lots.

Side Yards: Adequate side yards are needed to provide light and air between buildings. In particular, a noise and visual buffer is needed if windows are located on the side of a dwelling.

Rear Yards: Adequate rear yards are needed to provide an area for recreation, storage, clotheslines, etc.

B. Minimum lot sizes are specified where needed to:

1. Encourage development in those areas of the County established in the Comprehensive Plan as suitable for development;

2. Encourage compatible development;

3. Promote a healthy living environment.

Figure 4: Examples of Front, Side & Rear Yards

B. Exceptions

1. In the Rural District, a parcel recorded on or before October 21, 1974, may be eligible for a maximum of five lots of not less than three acres each before having to average lot sizes of not less than five acres each (or .2 units per acre). Additional development on the same parcel shall be limited to a density of .2 units per acre.

2. Lot size in the Rural District may be reduced to not less than one acre and 150 feet of lot width provided that:

a. The sale or transfer of such lots shall be limited to any parcel described and set forth in a deed recorded as of June 29, 1967, and

b. No more than three one-acre lots shall be permitted from any such parcel after June 29, 1967, and

c. Use of such lots shall be restricted to single-family residential purposes, and

d. If the original property has been subdivided:

i. And the owner of record as of June 29, 1967 retains a portion of the property, he may designate which parcel is eligible for the one acre lots, unless the right has already been legally conveyed by deed, or

ii. if the owner of record as of June 29, 1967 no longer owns the property and the eligibility has not been legally conveyed, all parties having fee simple interest in any portion of the original property must agree on which parcel or parcels will be eligible for the remaining unused one acre lots, and

e. If there are questions concerning eligibility for one acre lots, the burden of proof is on the applicant. A title search may be required. Decisions concerning eligibility for one acre lots are to be made by the Zoning Officer and may be appealed to the Board of Appeals with the decision based on the above provisions.

3. For lots properly approved and recorded before the adoption of this Ordinance, the following shall apply:

(2/27/92) a. Setbacks - The Zoning Officer shall apply recorded setbacks. If setbacks were not recorded, the Zoning Officer shall use the setbacks for a similar sized lot as indicated in Section 5 - 1.02 regardless of whether the lot is served by a community water or sewer system. If other existing structures in the community fail to meet the applicable side or rear setbacks, the Zoning Officer may reduce the minimum side or rear setback to that of other existing structures, so long as the reduction is given written approval by the adjoining property owners.

b. Lot Size - If a lot was legally recorded prior to the adoption of the Zoning Ordinance on June 29, 1967 or if it met the lot size requirements at the time it was recorded, that lot is buildable if:

i. The building can meet the minimum setbacks for a lot of equivalent size as per Section 5-1.02, and

ii. The lot receives Health Department approval, and

iii. the lot has adequate access to a road constructed to the standards specified in the Calvert County Road Ordinance.

c. Residue from Comprehensive Rezoning - If a portion of a recorded lot is comprehensively rezoned to Rural Commercial, the residue shall be considered a buildable lot if it meets the criteria in (a) and (b) above.

d. Lot Line Amendments - The Department of Planning and Zoning may approve lot line amendments for existing buildable lots so long as the amendment does not affect whether the lots are buildable. Health Department approval may be required.

 4. Zero Lot Line Development: Any interior side yard setback may be reduced to zero provided that the opposite side yard equals 25 percent of the site frontage. Where a zero side yard setback is used, the abutting  property must be held under the same ownership at the time of initial construction or the  owners of the abutting property must sign an agreement or deed restriction which grants consents in writing to such zero setback.

For the purpose of upkeep and repair of structures located adjacent to an interior property line, a maintenance easement shall be made a part of the property agreement or shown on a recorded plat. Such easement shall be an irrevocable covenant and shall run with the land.  Proof of said recorded easement shall be submitted to the Division of Inspections and Permitsprior to issuance of a building permit.

5. Transfer Zone District Lot Size:   Lots in Transfer Zone Districts may be reduced to one acre subject to criteria established in Section 4-3.

6. Low and Moderate Income Housing Development:  The Planning Commission has a commitment to make recommendations for the provision of  low and moderate income housing in Calvert County. These recommendations will be developed following a special study and an opportunity for citizen review and input. Approval by the County Commissioners is required for inclusion in the Zoning Ordinance.

(3/2/93) 7. Subdivision of Water Frontage Along Creeks and the Chesapeake Bay:  For new lots created after the adoption of this Ordinance, the following minimum lot widths on  the water are permitted only if a note is placed on the plat which states that no private piers are permitted. (See Section 5-4.07.B for community pier provisions.) This Section does not apply to waterfront lots adjacent to the shoreline of the Patuxent River.

a. Rural District - 100' width with the house site restricted to a location where the lot width satisfies Section 5-1.02.A. If a cluster subdivision is designed, there shall be a minimum 60' open space separating all clustered lots from year-around, free-flowing waterways.

b. R-1 and R-2 Districts - 50' width with the house site restricted to a location where the lot width satisfies Section 5-1.02.A. If a cluster subdivision is designed, there shall be a minimum 60' open space separating all clustered lots from year-around, free-flowing waterways.

c. Town Center District - There shall be a 25' minimum lot width on the waterfront.

(3/2/93) 8. Subdivision of water frontage along the main body of the Patuxent River:  The minimum lot width for lots adjacent to the main body of the Patuxent River shall be 25'.

 5-1.03 Lay-out and Design of Single-Family Residential Communities (1/4/93)

Residential communities outside Town Centers shall be designed to fit into the existing rural landscape in a manner that will retain the land's capacity to grow crops, produce timber, provide wildlife habitat, prevent soil erosion, provide recreational open space, contribute to maintaining clean water and air and preserve rural character. These features not only contribute to the health and welfare of County residents but also contribute to the economic base by providing jobs and revenues in resource-related and tourism-related enterprises. New buildings and roads shall be designed to enhance rather than to replace these important existing features. Site disturbance shall be held to a minimum.

A. Procedure

1. All of the requirements listed in the Calvert County subdivision regulations shall be met. Where there is a discrepancy between minimum standards or dimensions noted herein and other official regulations, the highest standard shall apply.

2. Applicability   A(5/28/96) The provisions of this Section apply to all single-family detached subdivisions outside of Town Center Zoning Districts with the following exceptions:

a. Agricultural Preservation Districts (APDs), from which transferable development rights have been sold, are exempt from these regulations.

b. Within designated Conservation Districts and Critical Areas, the provisions in Section 4-4 (Conservation Districts) and 4-6 through 4-9 (Critical Area) supersede this Section.

(5/28/96) c. In cases where the parent tract as of January 1, 1993 is less than twenty (20) acres, clustering is encouraged but not required. The applicant will have the option to do one of the following:

i. Design the subdivision as a conventional subdivision with the conventional building restriction lines; minimum lot widths and minimum lot sizes of the corresponding zoning district excepting that a front roadway buffer shall be provided in accordance with Section 5-1.03.D.5.b. or

ii. Design the subdivision as a cluster subdivision meeting all the requirements of Section 5-1.03.D. An adjacent property setback shall be provided along the perimeter of the parent tract (as of June 29, 1967) with cluster building restriction lines used internally. Such subdivisions must adhere to the minimum percentage of open space required for the corresponding zoning district described in Section 5-1.03.C.2. Such subdivisions must also adhere to the front roadway buffer requirement in accordance with Section 5-1.03.D.5.b.

(5/28/96) d. In cases where all proposed lots are a minimum of 20 acres, clustering is not required, provided that a note is recorded on the plat stating that no further subdivision of such lots is permitted.

3. Concept Plan

(5/28/96) a. Prior to submittal of an official subdivision application, a concept plan shall be submitted showing existing features and all potential building lots, roads, and other site improvements located in accordance with the provisions of this Ordinance. The purpose of this approach is to resolve problems before extensive engineering begins. In the event that any of the individual provisions of this Ordinance, relating to the placement of lots and roads (Section 5-1.03), conflict with each other as applied to a given site or that the permitted number of lots cannot be accommodated on the site under the provisions of this Ordinance, these conflicts shall be noted in writing by the applicant as part of the concept plan submittal. The Planning Commission or its designee may waive or reduce the requirement for a concept plan of the entire parent tract for certain minor subdivisions. Such waivers or reductions shall be granted on a case by case basis and limited to minor subdivisions where the proposal does not significantly impact the future layout and development of the parent tract (such as the creation of a lot containing an existing house or creation of a single lot on a large parent tract).

b. The concept plan submittal shall be accompanied by a soils map (1" = 600'), an aerial photograph (1" = 600'), a tax map (1" = 600') and a topographic map (1" = 600'), each showing the boundaries of the proposed lots, the boundaries of the parent tract and the locations and boundaries of any lots created from the parent tract since June 29, 1967.

D. Placement of Lots and Roads

The concept plan shall show the proposed size and locations of building lots. Lots and roads shall be located in areas where they will have the least effect on forests, sensitive areas and cropland and where they will contribute toward preserving and maintaining existing farm structures and historic structures, as well as the scenic and rural character of the County.

The Planning Commission may modify those provisions designated with an asterisk to the minimum extent needed to resolve conflicts between individual provisions of this Ordinance or to address unique site constraints.

(11/18/97) 1. Protection of Forested Areas and Wildlife Habitat

a. All of the provisions in the Calvert County Forest Conservation Program shall be met.

*b. Buildings and roads shall be located at forest edges or clustered in a manner that will maximize the amount of contiguous forested area left intact. The portion of the existing forested area that is to be retained should be determined with reference to the location of forested land on adjacent properties so as to maintain contiguity where feasible.

*c. Long roads and driveways (more than 400') penetrating into an existing forest shall be avoided.

2. Protection of Sensitive Areas

a. All of the provisions in the Calvert County Zoning Ordinance and Subdivision regulations governing protection of wetlands, floodplains, steep slopes, and blue line streams shall be met.

*b. Road and driveway crossings through wetlands, floodplains, steep slopes and blue line streams shall be avoided.

*a. Buildings and roads shall be located in a manner that will retain existing cropland, pasture and meadow and avoid dividing existing cropland.

*b. If the existing cropland, pasture or meadow has Class I, Class II and/or Class III soils, the buildable area may include up to 20% of the total area of cropland, pasture and meadow existing prior to subdivision. The portion of the open land that is retained should be determined with reference to the location of cropland on adjacent properties so as to maintain contiguity where feasible.

*c. If the cropland, meadow or pasture does not have Class I, Class II and/or Class III soils, up to 100% of the area may be converted to buildable area, provided all of the other conditions in this Ordinance are met.

4. Protection of Farm Structures and Historic Structures

*a. In the event existing farm structures (such as barns, outbuildings and fences) are located on the site, they shall be retained and included together with cropland, pasture and/or meadow as part of one or several farm lots.

b. In the event any building on the site is 50 years old or older, the Historic District Commission shall be notified to determine whether the building has historic merit.

d. The Planning Commission may require screening between existing farm and/or historic structures and new houses.

5. Protection of Rural Character, Scenic Vistas and Impact on Adjacent Properties

a. Buildings and roads shall be located in a manner that will maintain and enhance a visually attractive rural landscape.

(5/28/96) b. Front Roadway Buffer

Building sites shall be designed to afford the least visibility of the development from existing public roads. A front roadway buffer shall be provided along all public roads in the RUR, R-1, and R-2 Zoning Districts except along those roads that are internal to the subdivision.

The front roadway buffer shall meet one or more of the following requirements below.  Buffering along Rt. 4 shall be increased as indicated.

i. A naturally vegetated buffer at a minimum of 100' in width from the right-of-way line (200' in width from Rt. 4) into the parcel, or

ii. if a naturally wooded buffer does not exist, the applicant shall have the option of planting a 100'wide wooded buffer (200' wide wooded buffer adjacent to Rt. 4) as shown in Figure 5A. In instances where only part of a naturally wooded buffer exists, the existing buffer can be enhanced to a 100' wide wooded buffer with additional plantings as approved by the Planning Commission or its designee, or

iii. if open space is created along the roadside in a clustered subdivision, no plantings are required. The open space shall be a minimum depth of 200' from the edge of the road right-of-way (300' from Rt. 4). Houses adjoining the open space shall be arranged so that the rears of the houses are not visible from the road.

iv. Exceptions:

(a) The Planning Commission or its designee may reduce or waive the front roadway buffer for lots containing existing houses.

(b) The Planning Commission or its designee may reduce the front roadway buffer to a minimum 60' wide wooded or planted buffer to accommodate the conventional number of lots. Reductions in the front roadway buffer may not be granted in order to accommodate additional lots created through the use of Transfer Development Rights.

(c) The Planning Commission or its designee may reduce or waive the front roadway buffer if the proposed building design and site design significantly contribute to maintaining rural character consistent with published rural guidelines.

c. Adjacent Property Setback

In all clustered subdivisions in the Rural (RUR) Zoning Districts, a 100' adjacent property setback shall be provided along adjacent property boundaries. In the R-1 and R-2 Zoning Districts, the adjacent property setback shall be 50'. Entire septic recovery areas and/or wells may be located in the adjacent property setback.


i. The adjacent property setback shall not be required along any parcel or lot which has been created from the same parent tract defined as of June 29, 1967. Any new lots in a subdivision that adjoin such a previously created parcel or lot will have the same building setbacks as said parcel or lot.

ii. A subdivision less than twenty acres that under Section 5-1.03.A.2.c. is being designed as conventional subdivision shall not require an adjacent property setback. Conventional building setbacks shall be used instead.

iii. The adjacent property boundary setback may be reduced to the corresponding conventional rear building restriction line for that zoning district if written approval is given by the adjacent property owner. An adjacent property owner may not waive the requirement for a roadway buffer.

iv. Generally roads and driveways shall not be designed so that they are placed in the adjacent property setback that adjoins the rear lot lines of lots in an adjoining subdivision. However, driveways and roads may be located in the adjacent property setback to accommodate good site design such as avoiding environmentally sensitive areas (wetlands, wetland buffer areas, floodplains and conservation areas) and providing for shared entrances or entrances with the optimum sight distance.

(5/28/96) *d. Fencing such as cattle fencing and chain link fencing shall be required adjacent to all active farms and Agricultural Preservation Districts to protect fanning operations from intruders (i.e., dogs and off-road vehicles) that can cause damage to crops and farm machinery.

e. On-Site Roads

i. Exceptions to the Calvert County Road Ordinance may be approved by the County Engineer for the purpose of maintaining and/or creating a traditional rural community design, provided that the proposed exceptions are consistent with the Manual on Uniform Traffic Control Devices (MUTCD) and current American Association of State Highway and Transportation Officials standards (ASHTO).

ii. As part of road construction, on-site roads shall be planted outside the right-of-way on both sides with shade trees spaced a minimum 30 feet apart on center. This provision may be modified at intersections as needed to comply with sight distance requirements.

6. Community Design

*Buildings and roads shall be designed to promote a sense of community within the subdivision by creating a centralized community focal point such as a village green or community park, by providing on-site trails and walkways and by relating buildings to each other and to the designated open space within a coherent arrangement of buildings, open space and roads.

At minimum, buildings shall be arranged to avoid facing the front of a house onto the back of another house.

Trails, walks, and sidewalks shall be located outside the County right-of-way except where they Must cross the right-of-way. Maintenance of trails, walks, and sidewalks shall be the responsibility of property owners.

7. Provision of Open Space for Community Use and Recreational Areas
