Sec. 8.1.13 - Traditional Neighborhood Development (TND).
A.
(TND) Guiding Principles. The following is a summary of the guiding principles of a (TND):
1.
Principles of Public Realm.
a.
Well-designed places; terminal vistas.
b.
Non-residential buildings near or at the sidewalk.
c.
Lots are typically smaller and narrower than in conventional subdivisions.
d.
Rear access alleys allowed.
2.
Principles of Transportation System.
a.
Connected web of streets.
b.
Culs-de-sac are to be avoided and, where permitted, are short in length.
c.
Curved as well as straights streets may be provided.
d.
Short blocks.
e.
Sidewalks are located on both sides of the street.
f.
Two or more points of ingress and egress are provided for the (TND).
3.
Principles of Mixed Use.
a.
(TNDs) always contain a mixture of dwelling types (e.g., single-family detached, single-family attached, multi-family, dwellings atop of commercial uses, etc.).
b.
Denser housing is found near a designated "TND Center".
c.
Civic uses are encouraged within the (TND).
d.
Similar types of buildings should face each other on opposite sides of the street.
4.
Principles of Architecture.
a.
Commercial buildings should be of the "shop-front" variety that cater to the pedestrian.
b.
Other non-residential uses within the TND should also be designed so as to cater to pedestrians.
5.
Principles of the (TND) Center.
a.
Each (TND) must have at least one neighborhood center (i.e., TND Center) as a focal point of the community.
b.
The (TND) center is "ideally" located in the geographic center, although there may need to be some variation to this theme to insure that the center is viable. In certain instances, a nearby, established, and pedestrian-oriented center located outside the (TND) may serve as an alternative.
c.
The (TND) Center shall consist of one or more uses that serve the residents of the (TND) and can include retail, office and civic uses.
d.
With limited exceptions (i.e., financial institutions, ATMs), commercial uses should not be automobile oriented.
6.
Principles of Open Space.
a.
Compact development should result in preservation of open space.
b.
(TNDs) shall have public open spaces such as greens, village squares, parks or playgrounds.
c.
Smaller open space areas should be distributed throughout the (TND).
d.
Pre-existing natural features should be retained (to the greatest degree feasible) and be incorporated into the (TND).
7.
Principles of Civic Uses in (TNDs).
a.
Civic uses may serve (TND) residents only (swimming pools, meeting centers) or the community as a whole (church, school).
b.
For (TNDs) located on tracts of less than 25 acres, the (TND) Center can consist entirely of civic uses that serve the (TND) residents only.
B.
TND Development Guidelines.
1.
Allowed Zoning Districts. (TNDs) may be allowed in the (R-1), (R-2), (R-3), (RS-20), (RS-12), (RS-8), (RMF), (TMU), (OLC), (O-1), (CBD), (UMU), (C-1), and (I-U) Districts.
2.
Maximum Residential Density. None.
3.
Maximum Building Height (based on TND component).
a.
Village Residential - Three stories.
b.
Central Residential - Three stories.
c.
(TND) Center - Five stories, except three stories in (R-1), (R-2), (R-3), (RS-20), and (RS-12) districts as well as any (TND) not located in the Urban Standards (US) Overlay District.
4.
Minimum Lot Width. None, except 40 feet on any lot containing a detached single-family dwelling unit.
5.
Minimum (TND) Tract Area. Ten acres.
6.
Required (TND) Components. Each (TND) shall contain the following four components:
a.
(TND) Center: This is the "Main Street" of the (TND) and may be located within the center of the (TND) itself, or on the internal periphery of the (TND) along a major road emanating from an existing adjacent thoroughfare. Non-residential uses may include retail, office, civic and certain "high-tech, low-impact" manufacturing uses. Residences may also be located in freestanding buildings or on top of non-residential buildings. Civic uses may be located anywhere in the (TND) Center or in other portions of the (TND). If an established pedestrian-accessible town center (i.e., retail area, equal or greater in size to that which would have been required in the (TND) itself) lies within 2,400 linear feet (as measured by walking distance) from 75 percent of the residential units contained in the (TND), the (TND) Center requirement within the (TND) may be waived.
There may be more than one designated (TND) Center within the (TND); however, there shall be at least one designated "primary (TND) Center" that accommodates a minimum of 75 percent of the total acreage designated as "(TND) Center".
b.
Central Residential: This shall consist of higher-density residential development, along with civic uses, that lies adjacent (i.e., within ¼ mile walking distance from the edge of the primary (TND) Center) to the (TND) Center. Residential dwellings can include those of the attached and detached variety that are a maximum of three stories in height.
c.
Village Residential: The remaining developed portion of the TND shall consist of "village residential" uses that are limited to detached dwelling units.
d.
Open Space: Greenways, Parks, Greens, Village Squares, etc. (but not sidewalks or greenstrips), that meet the requirements of Section 11.7.
7.
(TND) Layout Requirements.
a.
Open Space: Open space shall be provided on a minimum of 20 percent of the gross acreage of the (TND). Such open space shall be in accordance with Section 11.7 of this Ordinance and shall be of such variety so as to be readily accessible to all residents of the (TND).
b.
(TND) Center: The (TND) Center shall constitute from ten to 25 percent of the gross acreage of the (TND).
c.
Central Residential: There is no maximum acreage standard for the Central Residential portion of the (TND).
d.
Village Residential: If all of the residential acreage lies within a one-quarter mile walking distance from the primary (TND) Center, there shall not be a required "Village Residential" component to the (TND) and the residential component of the (TND) can be satisfied entirely by the "Central Residential" component.
8.
Approval Process for a (TND).
(1) Irrespective of acreage within the (TND), a PIM and Conditional District zoning shall be required if either the (TND) Center or any multi-family residential buildings lie (1) directly across a public street from property not within the (TND); or (2) within 200 feet from the edge of a property line of a lot not located in the (TND) that is less than one acre in area and that contains a pre-existing single-family dwelling unit.
(2) The Administrator shall be required to meet with the developer and review the (TND) per Section 5.16.5(A) to ensure conformity to the Ordinance prior to the PIM being held.
9.
Uses Allowed Within the (TND).
Note:
1.
X = Use allowed by-right; S = Special Use Permit required
2.
If a use located in the TND is subject to the issuance of a Special Use Permit, and if such use were shown on the site plan originally approved for the (TND) through the conditional zoning process, issuance of a Special Use Permit for such use shall not be needed. In instances where such use was not indicated on and approved as part of the site plan for the conditional rezoning of the property for the (TND), or the (TND) were approved administratively, a Special Use Permit would need to be issued for such use.
3.
Additional specifications for building design and layout in (TNDs) are indicated elsewhere in this Section.
10.
Allowed Housing Types.
(1) Allowed only in (TNDs) with a gross acreage of 50 acres or greater and located within the Urban Standards (US) Overlay District. Such type use shall not be allowed in an (R-1), (R-2), (R-3), (RS-20), or (RS-12) zoning districts.
11.
Off-street Parking Requirements. The requirements of Chapter 10 shall prevail except the location of off-street parking shall be as provided for herein based on the building type (i.e., uses within the (TND) Center must have their parking located entirely within the (TND) Center.) Parking decks, if used, shall be of the Option "B" and "C" variety as contained in Sections 10.9.2 and 10.9.3 of this Ordinance.
12.
Screening Requirements. A minimum type B screening shall be provided along the perimeter of the (TND) in accordance with Section 11.4. Screening may be required within the (TND) based on the use types.
13.
Accessory Structure Requirements. Accessory structure requirements shall be the same as provided in Section 9.9 of this Ordinance, except as herein provided.
14.
Lighting, Noise, Odor Requirements. Lighting requirements shall be the same as provided in Section 9.13 of this Ordinance. Noise requirements shall be the same as provided in Section 9.23 of this Ordinance. Odor control requirements shall be the same as provided in Section 9.22 of this Ordinance.
