A. 
Purpose.
1. 
The PUD District is intended to encourage innovative land planning and site design concepts that achieve a high level of public benefits, environmental sensitivity, energy efficiency, aesthetics, high-quality development, and other community goals by:
a. 
Reducing or eliminating the inflexibility that may result from strict application of the standards of this Code that were designed primarily for individual lots;
b. 
Allowing greater freedom in selecting the means to provide access, site design, open space, and design amenities;
c. 
Promoting quality urban design and environmentally sensitive development by allowing development to take advantage of special site characteristics, locations, and land uses;
d. 
Requiring compliance with development standards that reflect the high level of public investment in adjoining lands; and
e. 
Facilitating implementation of the Lake Saint Louis Comprehensive Plan and development in the interest of health, safety and welfare of the residents of Lake Saint Louis.
B. 
Previously Approved Planned Developments.
1. 
The following zoning districts and developments, including development plans and any associated text and standards, which were approved prior to the effective date of this Code are now designated as separate PUD Overlay Districts, and shall continue in effect and be considered legally conforming under this Code:
a. 
Properties with a prior zoning designation of Planned Development District (PD) or Planned Residential District (PR), and which have been platted, developed, or granted approval of a preliminary development plan or final development plan that is valid as of the effective date of this Code.
b. 
Areas platted prior to March 21, 1978, and subject to a zero lot line development concept, more specifically identified as the Patio Cove I, Patio Cove II, Patio Cove III, and Patio Green subdivisions.
2. 
Developments identified in Subsection (B)(1) shall be subject to all applicable standards of this Code, including those of the underlying base zoning district, except where expressly modified by this Article or by a previously approved ordinance, resolution, plan, plat, or other approval.
3. 
Preliminary development plans, final development plans, and site plans for areas approved prior to the effective date of this Code for developments identified in Subsection (B)(1) will be considered to be Master Plans (Section 405.150) or site plans (Section 405.160), as determined by the Community Development Director.
4. 
Any proposed modification of a previously approved planned development listed in Subsection (B)(1) shall be reviewed in accordance with the requirements of this Article.
C. 
Eligibility.
1. 
An application for a Zoning Map amendment (Section 405.100) to include a property in the PUD Overlay District may only be accepted for review and consideration if the application meets the following criteria:

Need. The proposed development could not be developed using conventional zoning districts or standards.
b. 
Minimum Size. At least one of the following criteria is met:
(1) 
The development includes a contiguous area of at least five (5) acres; or

The development contains at least fifty thousand (50,000) square feet of nonresidential gross floor area; or
(3) 
The development contains at least one hundred (100) dwelling units.
c. 
Unified Control.

This provision shall not prohibit a transfer of ownership or control, provided that a unified ownership remains.

Requests to include property in a PUD Overlay District require the concurrent approval of the following applications:

c. 
Site plan (Section 405.160); or

Master Plan (Section 405.150).

The PUD Overlay District shall be applied over the underlying base zoning district and depicted accordingly on the Official Zoning Map (e.g. "R1-PUD" or "C1-PUD").
E. 
Regulatory Flexibility.
1. 
Unless otherwise expressly allowed by this Article and approved by the Board of Aldermen during the approval process, property located in the PUD Overlay District shall be subject to all applicable standards of this Code, including those of the underlying base zoning district.
2. 
To encourage flexibility and creativity, the Board of Aldermen may impose additional standards beyond those contained elsewhere in this Code and may approve specific exceptions from or modifications to the requirements of the underlying base zoning district and other requirements of this Code as a part of the approval process.
3. 
Any regulatory modification shall be approved through a finding by the Board of Aldermen that:
a. 
The modification addresses a unique situation.
b. 
The project provides public benefits to the City in an amount proportional to the number and degree of requested regulatory modifications. Public benefits include but are not limited to architectural distinction, new or enhanced public infrastructure, sustainable site and/or building features, land dedication, public art, open space and landscaping, or enhancements to off-site City-owned parks or other public facilities.
c. 
The development quality is better than what could have been accomplished through the strict application of the base zoning district standards or other standards of this Code.
