Phase 1C - Engineering Content

Generate the Phase 1C Engineering Content by comparing the 2023 and 2026 NJ Stormwater BMP Manual guidance on: • Stormwater pollutant removal criteria (TSS and related treatment standards) • SWM standards and computations (e.g., design storm inputs, runoff volume/rate concepts, sizing logic where described) • Groundwater recharge requirements and design constraints

Use the uploaded manual documents as reference material.

Output: Write a structured engineering summary suitable for a technical training guide. Organize the response using the sections below and focus on what an engineer or reviewer would need to know.

  1. Pollutant Removal (TSS and Treatment Requirements)
  2. What the manuals require
  3. Where designers typically document compliance

  4. Notable updates between 2023 and 2026

  5. SWM Standards and Computations

  6. What standards drive sizing/verification
  7. What computations are commonly referenced (conceptually; do not invent site-specific numbers)

  8. Notable updates between 2023 and 2026

  9. Groundwater Recharge

  10. Recharge requirement concepts and applicability
  11. Common constraints (soil, SHWT separation, liners, prohibited infiltration areas if referenced)

  12. Notable updates between 2023 and 2026

  13. Practical Design and Review Implications

  14. What changes in design workflow
  15. What changes in documentation expected in a submittal
  16. Typical reviewer “gotchas” (only if supported by manual language; avoid speculation)

Constraints: - Do not reference or call any tools, functions, file-writing steps, or completion commands. - Do not list file paths. Assume the manuals are available via uploaded assets. - If a detail is not found in the provided manuals, state that it is not explicitly specified rather than guessing.
