Wake Forest Unified Development Ordinance - July 2022

Erosion, Flood, Stormwater & Watershed Standards 12.1 General Purpose And Intent


1. It is the purpose of this section to promote public health, safety, and general welfare and to minimize public and private losses due to flood conditions within the flood prone areas by provisions designed to: a. restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards or that result in damaging increases in erosion, flood heights or velocities; b. require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction; c. control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters; d. control filling, grading, dredging, and all other development that may increase erosion or flood damage; and e. prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or which may increase flood hazards to other lands. 2. Specific objectives of the flood damage prevention provisions are as follows: a. to protect human life and health; b. to minimize expenditure of public money for costly flood control projects; c. to minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; d. to minimize prolonged business losses and interruptions; e. to minimize damage to public facilities and utilities; f. to help maintain a stable tax base by providing for the sound use and development of flood prone areas; and g. to ensure that potential buyers are aware that property is in a Special Flood Hazard Area. C. Stormwater Management: The purpose of this section 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 post-development stormwater runoff and nonpoint and point source pollution associated with new development and redevelopment. This ordinance seeks to meet its general purpose through the following specific objectives and means: 1. Establishing decision-making processes for development that protects the integrity of watersheds and preserves the health of water resources; 2. Requiring that new development and redevelopment maintain the pre- development hydrologic response in their post-development state as practicable for the applicable design storm in order to reduce flooding, stream bank erosion, nonpoint and point source pollution and increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats; 3. Establishing minimum post-development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality; 4. Establishing design and review criteria for the construction, function, and use of structural SCMs that may be used to meet the minimum post- development stormwater management standards; 5. Encouraging the use of better management and site design practices, such as the use of vegetated conveyances for stormwater and the preservation of greenspace and other conservation areas to the maximum extent practicable;
