It addresses how to handle projects in various stages of development, providing guidance on applying the updated technical standards and post-construction control practices, promoting consistent stormwater management across the state and ensuring that all new and redevelopment projects utilize the most current and effective strategies.
Relationship with Construction General Permits
The Construction General Permit (CGP) mandates the use of the 2015 Design Manual for developing Stormwater Pollution Prevention Plans (SWPPPs). These plans are essential for managing stormwater runoff from construction sites.
Requirements for SWPPPs in Construction Projects
Construction projects disturbing one acre or more in New York State are required to develop and implement a Stormwater Pollution Prevention Plan (SWPPP). These plans, guided by the New York State Stormwater Management Design Manual, must detail measures to control erosion and sediment, prevent pollutants from entering waterways, and comply with the State’s standards. SWPPPs also need to address post-construction stormwater management to ensure long-term water quality protection. The manual provides detailed technical guidelines for creating effective SWPPPs.
Stormwater Management Practices (SMPs)
The manual offers standards for designing Stormwater Management Practices (SMPs) to safeguard New York State’s waters from urban runoff. These standards ensure effective and environmentally sound water management.
Standards for SMP Design
The New York State Stormwater Management Design Manual provides specific standards for the design of Stormwater Management Practices (SMPs). These standards focus on protecting the state’s waters from the harmful effects of urban stormwater runoff. The manual offers guidelines on sizing, selecting, and locating SMPs at development sites to ensure compliance with state performance standards. These standards are essential for designers aiming to create effective and sustainable stormwater management systems. The design process includes considering various factors to maximize the efficacy of SMPs while minimizing their environmental impact.
Integration of Green Infrastructure
