§ 18-435. General provisions.

(a)

Purpose. The purpose of this article is to protect, maintain and enhance the public health, safety, environment and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased postdevelopment stormwater runoff and nonpoint source pollution associated with new development and redevelopment. It has been determined that proper management of postdevelopment stormwater runoff will minimize damage to public and private property and infrastructure, safeguard the public health, safety, environment and general welfare of the public, and protect water and aquatic resources. This article seeks to meet that purpose through the following objectives:

(1)

Establish decision-making processes surrounding land-development activities that protect the integrity of the watershed and preserve the health of water resources;

(2)

Require that new development and redevelopment maintain the predevelopment hydrologic response in their postdevelopment state as nearly as practicable in order to reduce flooding, stream bank erosion, nonpoint source pollution, and maintain the integrity of stream channels and aquatic habitats;

(3)

Establish minimum postdevelopment stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality;

(4)

Establish design and application criteria for the construction and use of structural stormwater control facilities that can be used to meet the minimum postdevelopment stormwater management standards;

(5)

Encourage the use of nonstructural stormwater management and stormwater better site design practices, such as the preservation of green space and other conservation areas, to the maximum extent practicable;

(6)

Establish provisions for the longterm responsibility for and maintenance of structural storm water control facilities and nonstructural stormwater management practices to ensure that they continue to function as designed, are maintained, and pose no threat to public safety; and,

(7)

Establish administrative procedures for the submission, review, approval and disapproval of stormwater management plans, and for the inspection of approved active projects, and longterm follow up.

(b)

Applicability. All persons proposing development and/or construction within the city shall submit a stormwater management plan and hydrology study to the city manager for review of conformity with this article, except as provided herein. These standards apply to any new development or redevelopment site that meets one (1) or more of the following criteria:

(1)

New development that involves the creation of five thousand (5,000) square feet or more of new impervious cover, or that involves other land development activities of one (1) acre or more;

(2)

Redevelopment that includes the creation, addition or replacement of five thousand (5,000) square feet or more of new impervious cover, or that involves other land development activity of one (1) acre or more;

(3)

Any new development or redevelopment, regardless of size that is defined as a hotspot land use;

(4)

Land development activities that are smaller than the minimum applicability criteria set forth herein if such activities are part of a larger common plan of development, even though multiple, separate and distinct land development activities may take place at different times on different schedules.
