  • SWPPP Development and Approval
  • Stormwater Management System Design
  • Green Infrastructure Design
  • Permit Issuance
  • SWPPP Compliance Inspections

Koysman Engineering (Koysman) provided civil engineering and inspection services for the development of a new 9-story mixed use building located at 828 Metropolitan Avenue in Brooklyn, NY.

Koysman developed a detailed SWPPP for the project site. The SWPPP consisted of a vast array of pollution prevention methods for construction site stormwater runoff. Additionally, the SWPPP included a full-depth post construction stormwater management plan, which consisted of the implementation of retention, evapotranspiration, and detention stormwater management practices. Koysman provided a detailed design of the stormwater management system for the building, making use of the state-of-the-art green infrastructure practices to meet and exceed stringent NYCDEP rules and regulations. Green infrastructure practices used for this project include green roof and stormwater planter, coupled with planting schedules for reliable, long-term performance. Koysman ensured an expedited SWPPP approval process through continuous coordination with NYCDEP reviewers and all stakeholders.

Koysman provided SWPPP inspection services throughout the duration of construction, to ensure all SWPPP requirements were met on-site, and Koysman facilitated all communication with NYCDEP staff, to ensure the construction process could proceed with minimal issues.
