The purpose of the Residential Overlay District is to establish criteria to regulate "new development" defined as construction on vacant, underutilized, or reused parcels of land generally served by utilities and surrounded by existing development, including single-family homes including additions as defined in this section under "new development". The intent of the Residential Overlay District is to:

1.

Maintain streetscape character while accommodating new residential development.

2.

Address and mitigate the impacts of new development on stormwater management and loss of tree canopy within established residential areas and provide tree save incentives.

3.

Provide options for parking on lots under construction in order to limit roadway parking.

(Ord. No. 847, § 2(Exh. B), 4-18-2022)

The provisions of this article are intended to regulate development within single-family residential areas and shall apply to all parcels designated "Residential Overlay District" on the official zoning map currently restricted to Stonegate Manor, Meadowbrook and Milton Estates. All development, including construction of new homes and/or applicable additions to homes as defined by this overlay, shall be in accordance with the provisions of the zoning ordinance and land development regulations, as well as this article. In the event of a conflict or inconsistency between the provisions of this article and any other provision of the Unified Development Code, this article shall govern the development of the property within the boundaries of the overlay.

The overlay applies to all New Development that includes one or more of the following:

1.

Any development on vacant or unused lots

2.

Redevelopment of more than one-third (1/3) of the existing or preexisting building footprint

3.

An addition or accessory dwelling exceeding the lesser of 600 square feet or 20% of existing building footprint

(Ord. No. 847, § 2(Exh. B), 4-18-2022)

A.

Design Standards for New Development, as defined on the previous page.

1.

Where a garage faces a street the garage must be recessed a minimum distance of 20 feet behind the front building facade.

2.

Architectural Variety. Proposed residences within an established neighborhood must incorporate architectural variety to their front facade, ensuring housing style diversity. Duplicative front facade elevations adjacent to each other are prohibited. Simple reverse configurations of the same facade elevation on adjacent lots are not sufficient to meet this requirement. In order to ensure architectural variety, three or more design elements per infill residence must be utilized:

a.

Different window opening locations and designs;

b.

Different roof line configurations:

c.

Different entry/porch designs;

d.

Different exterior materials and finishes;

e.

Different garage location, configuration, and design.

B.

Stormwater design requirements (Previously adopted March 2022)

1.

Soils infiltration testing prior to issuing any development permit required to install an infiltration practice for all development that adds between 1,000 SF and 5,000 SF of new impervious area. The soils infiltration testing will include:

a.

infiltration rates

b.

depth to water table

c.

depth to bedrock.

2.

Certification that the green infrastructure measure was installed as designed at the end of construction shall be required as well as a maintenance covenant be recorded with the property records office for all future homeowners.

3.

Development that adds or replaces 5,000 SF of more of impervious area shall complete:

a.

a full stormwater management study

b.

soil testing

c.

measure certification

d.

recording of a maintenance covenant.

C.

Land Disturbance

1.

Silt Fencing shall be permitted to be set back from the existing roadway by up to 20' from the edge of pavement for the purpose of creating a gravel area to assist with sub parking as well as material drop off. This area shall be maintained to avoid tracking into the roadways.

(Ord. No. 847, § 2(Exh. B), 4-18-2022)

To maintain and promote the public health. safety, and welfare. the city has established city-wide regulations governing the conservation, planting. and replacement of trees. Trees contribute to the community's quality of life, improve the visual quality of the city, assist with rainwater interception and infiltration, and increase property values. These overlay guidelines will apply above and beyond the City's Land Development Ordinance to address the specific challenges and conditions of tree preservation within the overlay's boundaries and provide additional incentives for saving existing trees.

A.

Deviations from Unified Development Code.

1.

Minimum Tree Density. Within the overlay district boundaries, all 'For-Sale' residential lots shall maintain a minimum tree density as described in section 3.2.7 of the Tree Ordinance by making reasonable efforts to incorporate existing trees on the property, especially within the streetscape. (Reasonable efforts shall include. but not be limited to. alternate building design. building and driveway location. stormwater BMP locations).

2.

Rear landscape Strip. Within the overlay district boundaries, all 'For-Sale' residential lots shall include a 10' undisturbed or replanted landscape strip along the rear property line.

a.

If property includes stream buffers. floodplain, or other zoning buffers, this rear buffer location and width maybe shifted. removed or altered as approved by the city Arborist to accommodate alternate layouts.

3.

Additional Tree Credits. The City Arborist may authorize additional tree credits for trees preserved with an approved alternate design.

a.

Specimen trees may receive a density credit of three times the inches as long as the encroachment into the critical root zone is below 20%. Trees of Quality and Tree Groupings may reduce recompense plantings. The reduction shall be calculated considering two times the inches of the Trees of Quality or Tree Groupings that are preserved as long as the encroachment into the critical root zone is below 20%.

4.

Tree Replanting. Replanted trees shall be native and ecologically compatible with the local environment and uptake or intercept stormwater.

a.

It is desirable to plant at least 20% medium or large evergreens as specified in the tree list in the Guidance Document to enhance the interception of rainfall year-round.

b.

Trees selected for minimum tree density plantings shall be water loving species, such as Red maple, Weeping willow, Black gum, River Birch. Bald Cypress, American Sycamore, Atlantic White Cedar, Alder, Sweetbay Magnolia or similar as approved by the City Arborist.

c.

Streetscape/Landscape strip trees shall be planted in the front yard along the road frontage within the 10' landscape strip. Alternative designs and locations may be considered where existing utilities conflict with these requirements.

d.

Spacing and number of trees shall be calculated based upon the average canopy spread of the species selected, as outlined in the Arborist Guidance document, in relation to the linear length of property road frontage.

e.

When tree spacing exceeds 30' OC, at least one ornamental tree shall be incorporated into the design and planted in the front yard.

f.

In order to create/maintain street character shade trees selected for the streetscape shall be overstory canopy trees of the Quercus (oak), Acer (maple), Ulmus (elm), and Platunus (sycamore) genus or as approved by the City Arborist.
