A.
There is a general presumption that an application for a PUD project at an appropriate location conditionally approved as a PN District, proposing uses permitted within the PN District with residential densities as provided in this section, inures to the general benefit of the Town and is in compliance with the Town's Comprehensive Plan.
B.
Applicability. The Town Council may apply the PN Planned Neighborhood District to any lands annexed by the Town that have not been rezoned prior to the original adoption of this section, Ordinance No. 446, adopted May 3, 2004, and effective May 10, 2005. The PN District is intended to apply to tracts of land exceeding 50 acres.
C.
Intent. The PN Planned Neighborhood District is intended to promote the following:
(1)
Implement the recommendations of the Denton Comprehensive Plan;
(2)
Develop neighborhoods that are pedestrian-friendly and encourage pedestrian travel;
(3)
Promote design that results in residentially scaled buildings fronting on and generally aligned with streets;
(4)
Encourage the inclusion of a diversity of household types, age groups, and income levels;
(5)
Promote traditional town building and site development patterns with an interconnected and broadly rectilinear pattern of streets, alleys, and blocks to accommodate both pedestrians and automobiles;
(6)
Encourage the creation of functionally diverse but visually unified communities focused on central squares;
(7)
Promote the use of neighborhood greens, landscaped streets, boulevards, and single-loaded parkways woven into street and block patterns to provide space for social activity, parks, and visual enjoyment;
(8)
Provide buildings for civic or religious assembly or for other common or institutional purposes that act as visual landmarks and symbols of identity;
(9)
Promote the location of dwellings, shops, and workplaces in close proximity to each other, the scale of which accommodates and promotes pedestrian travel for trips within the community;
(10)
Preserve open space, scenic vistas, agricultural lands, and natural areas;
(11)
Permit design flexibility to achieve an appropriate mix of residential and nonresidential building uses and
(12)
Require efficient utilization of designated growth areas.
D.
Land uses in the PN District. The uses permitted within the PN District shall be as established by the land use table set forth in this chapter, which shall prevail over conflicting requirements of this chapter or the Subdivision Regulations, Chapter 73, Land Subdivision.
E.
Density determination.
(1)
General. The total number of dwelling units permissible in a PUD project in the PN District shall be determined in accordance with the provisions of this section (as adjusted by density bonuses as set forth below), subject to the following:
(a)
Areas used for nonresidential purposes shall be subtracted from the adjusted tract acreage, as described in Subsection E(2) below, before determining permissible residential density.
(b)
All dwelling units constructed above commercial uses in the storefront area shall be permissible in addition to the number of dwelling units otherwise authorized under this section. However, the total number of dwelling units in a development shall not be increased by more than ten (10) dwelling units or 5%, whichever is greater.
(c)
Base density calculation. The land area shall determine base density yielded through calculations of the adjusted tract acreage (also defined as "net area"), as determined by Table E(2). The minimum residential density for a proposed PN District shall be 3.5 dwelling units per adjusted tract acres. Except as may be provided below, the maximum residential density for a proposed PN District shall be no more than 5.0 dwelling units per adjusted tract acre.
(2)
Table E (2) Table Density Factors for Calculating Adjusted Tract Acreage Density.
Factor | Description of Constraint | |
|---|---|---|
DF 1 | 0.00 | Street rights-of-way, floodways within one-hundred-year floodplain; wetlands and soils classified as "very poorly drained"; utility easements for high-tension electrical transmission lines (less than 69 KV); steep slopes, that is, those greater than 25%; soils classified as "poorly drained" (in unsewered areas); one-hundred-year floodplain (excluding floodways or wetlands within the floodplain); additional environmental constraints, such as FIDS and other habitat areas |
DF 2 | 0.05 | Resource Conservation Area of Critical Area Buffer): shall be applied only to area components not constrained by DF 1 |
DF 3 | 0.75 | Soils classified as "poorly drained" (in sewered areas); slopes between 15% and 25% |
DF 4 | 1.00 | Unconstrained land |
(3)
Density incentives to further certain public objectives.
(a)
Housing type diversity. A density increase of up to 5% is permitted at the discretion of the Town Council when the proposal provides a mixture of at least four of the five of the following types of housing: single-family detached, two-family (semidetached), multifamily, townhouse, and apartments. The architecture of the proposed dwellings shall be harmonious among the various housing types, and they shall be integrated physically; that is, they should not be separated into different neighborhoods but rather mixed in together on the same streets so that at least two dwelling types are located together within the same block.
(b)
Implementation. For each of the public purposes described in Subsection E(3)(a) above, if the Town Council is satisfied that the public purpose objectives are being satisfied, density bonuses may be implemented by reducing the minimum lot area requirements up to 20%. The cumulative density bonuses applied to a PUD project may not exceed 10% of the maximum residential base density.
F.
General design requirements.
(1)
Design standards referenced in this section shall be considered as minimum performance standards for the PN District.
(2)
Planned neighborhoods are intended to provide for a range of complementary uses. They may consist of up to four use areas: single-family residential areas (SRAs), central residential areas (CRAs), storefront areas (SAs), and conservation areas (CAs). At a minimum, they must contain both a SRA and a CA. These areas are intended to provide for the diversity necessary for traditional town life while maximizing the interactions among related uses and minimizing the adverse impacts of different uses upon each other.
(a)
Single-family residential areas (SRAs) provide locations for a broad range of housing types, including single-family detached, semidetached, and attached, and may also include accessory dwelling units. SRAs may include the Rural Conservation District (Resource Conservation Area of the Critical Area); however, no more than one detached single-family residential dwelling unit and one caretaker dwelling unit may be allowed per 20 acres and shall be subject to award of growth allocation. See § 128-24.
(b)
Conservation areas (CAs) are permanently protected open spaces, including greens, commons, passive and active recreation areas, environmentally sensitive and constrained areas, habitat protection areas, and private noncommon acreage used for agriculture, wholesale nurseries, tree farms, equestrian facilities, etc.
(c)
The central residential area (CRA) is intended to contain a variety of housing options and related uses.
(d)
The storefront area (SA) is intended primarily to provide uses that meet the retail and service needs of a traditional community center and its vicinity within one- and two-story buildings. It may contain other compatible uses, such as civic and institutional uses of community-wide importance, specifically including second-floor residential uses.
G.
Development standards.
(1)
The following development standards shall apply to the PN District:
(a)
The setback, lot size, lot dimensions, lot coverage, height, and yard requirements in the PN shall be established for each project by the Planning Commission in accordance with the PN design guidelines in Appendix III. In establishing these requirements, the Planning Commission shall consider such factors as the proposed development intensity and the existing character of adjacent neighborhoods.
(b)
Land coverage. The maximum amount of land that may be built over (covered) by parking lots, roads, sidewalks, plazas, buildings, or other structures shall be 60% of the adjusted tract area of the PN property(ies).
(c)
Minimum required open space.
(i)
Minimum open space, including parks, recreational, habitat, forest, agriculture, stream buffers, and wetland preservation areas, shall be provided as prescribed in Article XII Common Open Space. Not less than 50% of the minimum required open space shall be in a form usable to and accessible by the residents, such as a central green, neighborhood squares or commons, recreational playing fields, woodland walking trails, other kinds of footpaths, a community park, or any combination of the above.
(ii)
Open space land shall be permanently protected through conservation easements and may be developed for uses consisting of the following:
[1]
Agricultural uses, including horticultural, wholesale nurseries and the raising of crops, and buildings related to the same;
[2]
Equestrian facilities, including related stables and pastures;
[3]
Woodlots, arboreta, and other similar silvicultural uses;
[4]
Woodland preserve, game preserve, wildlife sanctuary, conservation meadows, or other similar conservation uses;
[5]
Municipal or public uses, public park or recreation area owned and operated by a public or private nonprofit agency, or governmental or public utility buildings or uses, not to include business facilities, storage of materials, trucking or repair facilities, the housing of repair crews, or private or municipal sanitary landfills; and
[6]
Active or passive recreation, if it is noncommercial and provided that no more than 50% of the minimum required open space is so used. Parking areas and any roofed structures associated with the active recreation may not be included within the 50% minimum.
(iii)
The required open space shall be located and designed to add to the visual amenities of neighborhoods and the surrounding area by maximizing the visibility of internal open space as terminal vistas (the building or landscape seen at the end of a street or along the outside edges of street curves) and by maximizing the visibility of external open space as perimeter greenbelt land (the undeveloped and permanently protected acreage around a community). Such greenbelt open space shall be designated to provide buffers and to protect scenic views as seen from existing roadways and public parks and shall not be less than 100 feet deep.
(iv)
PN developments shall include multiple greens, commons, or passive parks measuring a total of at least 1,500 square feet for each dwelling unit, plus 500 square feet of land for active recreation per dwelling unit.
(v)
Civic greens or squares shall be distributed throughout the neighborhood so as to be located within 1,500 feet of 90% of all residential units in the SRA and CRA areas.
(2)
Residential unit mix. At a minimum, each PN development shall have at least three of the five unit types. Each phase of a proposed PN shall have at least three of the five unit types. The Planning Commission may vary this phase requirement if satisfied that at build-out, three of five unit types are included in the overall PN development. Each phase of a proposed PN development shall provide housing opportunities for a diverse population mix of age groups and income levels.
Unit Type | Minimum Percentage | Maximum Percentage |
|---|---|---|
Detached single-family dwelling | 50 | 80 |
Two-family dwelling | 10 | 40 |
Townhouse | 5 | 20 |
Multifamily | 5 | 10 |
Apartment | 5 | 10 |
H.
Small PN projects. The Town Council may modify the minimum standards established in Subsection F above for a PN development of less than 50 acres, provided:
(1)
The proposed PN development is shown as part of and integrated into a general development plan for an adjacent (larger) PN project; the applicant demonstrates that the proposed development could be integrated into an adjacent development(s) or neighborhood(s) by such features as street extensions, the location of its SAs, and the location of common areas; and the Town Council determines that the proposed design meets the goals and objectives of the Comprehensive Plan and the intent of this section; or
(2)
The Town Council may find that the proposed PN is an infill or transition project between existing developments and/or adjacent to a proposed or planned large- scale PN project and that the proposed design of the PN project is consistent with the goals and objectives of the Comprehensive Plan and the intent of this section.
(3)
All PN projects shall be consistent with the PN design guidelines.
