Wet Pond

This page is a source-backed entry point for the wet-pond concept, but the live citations layer needs to be read carefully here. The page is anchored to Chapter 10.5, while the live crosswalk also uses Chapter 11.6 to keep the non-GI classification explicit. The page therefore stays conservative: a large-scale permanent-pool BMP with strong treatment and storage value, but not a substitute for GI by default.

Structured citation evidence for this page lives in the sibling claim manifest.

Overview

In the live source set, a wet pond is a large-scale permanent-pool BMP built around residence time, settling, and outlet control. The current source-backed reading should treat it as a storage-and-treatment facility first, not as an automatic GI credit mechanism.

Source Mapping

The live citations layer resolves this route directly to the following canonical source bundles.

  • Route type: canonical
  • 2023 source bundle: Chapter 10.5 (2023_BMP_10_5) - Wet Ponds (Large-Scale GI)
  • 2026 source bundle: Chapter 10.5 (2026_BMP_10_5) - Wet Ponds (Large-Scale GI)

Key verified claims already tied to this page manifest: - Wet ponds are source-backed through Chapter 10.5 as permanent-pool treatment and storage BMPs. - The live citations layer keeps wet-pond non-GI caution explicit through the Chapter 10.5 and 11.6 pairing. - Wet-pond maintenance stays tied to forebay, outlet, sediment, and structural component condition.

Design Criteria

The reconciled design criteria below come from the live crosswalk and page-level claim set, not from the older narrative snapshot.

This route does not have a dedicated parameter table in the crosswalk, so the controlling criteria stay tied to the verified claims and canonical source-bundle mapping below.

Source-backed criteria that still control this route: - Wet ponds are source-backed through Chapter 10.5 as permanent-pool treatment and storage BMPs. - The live citations layer keeps wet-pond non-GI caution explicit through the Chapter 10.5 and 11.6 pairing. - Wet-pond maintenance stays tied to forebay, outlet, sediment, and structural component condition.

Siting Constraints

The current source-backed siting review should focus on:

  • whether the available footprint, structural layout, and maintenance access are realistic for a pond-scale facility
  • whether the design is being over-claimed as GI when the live source model treats the non-GI reading as the safer baseline
  • whether the project is drifting into dam-safety or other out-of-corpus authorities that are not yet enrolled in Sources/*

Maintenance

Maintenance remains pond-centered:

  • protect forebay and permanent-pool function
  • keep outlet structures and emergency flow paths working
  • treat sediment buildup and structural component condition as operating risks, not cosmetic issues
