[Amended 2-17-2011 by Ord. No. 2010-29]
[1]
Editor's Note: Former Art. XV, Planned Districts, as amended, was repealed 2-17-2011 by Ord. No. 2010-25.
The purpose of this article is to establish regulations for Planned Districts that will coincide with the general pattern of land use established by this chapter for the development of the Town and to further the purposes set forth in § 340-2 hereof. Planned districts are established herein to encourage development of harmonious, efficient and convenient neighborhoods and business developments by promoting variety in land use, residential density and site design through clustering of buildings and preservation of unique natural features of the site. Additionally, the intent of this article is to ensure that Planned Districts:
A. 
Promote the conservation of energy and energy-efficient patterns of development;
B. 
Provide for the protection of existing and planned public drinking water supplies, their tributaries and watersheds;
C. 
Provide adequate, safe, and efficient transportation systems;
D. 
Avoid congestion by relating types and levels of development to the capacity of the circulation system, and maintain a safe level of service of the system;
E. 
Provide for pedestrian access to and between public and private facilities, including, but not limited to, schools, employment centers, shopping centers, recreation areas and residences;
F. 
Maintain harmony with neighboring uses;
G. 
Provide standards for and requirements of provisions for adequately and properly designed physical improvements, including plantings and proper property maintenance;
H. 
Further the accomplishment of the goals of the affordable housing element of the Town's Comprehensive Community Plan;
I. 
Preserve the unique natural features of the site; and
J. 
Create a cohesive campus-like development that features walkablity and integration of uses. A campus-like project includes various interrelated uses and a shared pedestrian and vehicular circulation pattern, with the potential for a common focal point, gathering space, or open space.

B. 
Planned Mixed Use Development District. A Planned Mixed Use Development District ("PMUD") is a type of Planned District in which a mixture of land uses are contained within a single development, building, tract or parcel. A Planned Mixed Use Development District shall meet the following criteria:

(5) 
Must be located in an area where the predominant surrounding vicinity zone and/or use is business, institutional/government, and/or multifamily;
(6)

The tract of land for a planned development shall consist of not less than the following minimum lot criteria and NET area requirements after freshwater wetlands, wetland buffers, slopes in excess of 8%, easements, and previously developed (not proposed for redevelopment) areas have been deducted from the following land area calculations:
(1) 
Net area equal to at least 20 acres unless the Planning Board and Town Council approve a waiver of this requirement where the Planning Board finds that the proposed area provides adequate and suitable area for the use(s) proposed to be added, and is consistent with the goals and purposes of Planned Districts as set forth in § 340-92, and provides for a campus-like setting with an efficient, integrated pattern of development providing for easy pedestrian access to and between facilities and other pedestrian-friendly amenities; has adequate and suitable infrastructure and parking and properly manages traffic safety and circulation issues; has suitable designed physical improvements, including plantings and landscaped buffering for the protection of abutters; and is consistent with the Town's Comprehensive Community Plan.
