Dry Detention¶

This page is a source-backed entry point for the dry-detention concept, but the live citations layer resolves it through BMP Manual Chapter 11.2 rather than through a standalone dry-detention chapter. The page therefore stays honest about the source basis: a derived basin concept anchored to the extended-detention source bundle.

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

Overview¶

In the live source set, dry detention should be read as a variant of the Chapter 11.2 extended-detention basin concept rather than as a separate authority. The useful distinction is the operating condition, not a separate source chapter.

Source Mapping¶

This route is retained for site navigation, but the live citations layer flags a taxonomy or classification caution for it.

Route caution: Dry detention (extended detention without wet pool) is likely a variant of Ch. 11.2 Extended Detention Basins. There is no separate 'dry detention' BMP Manual chapter. Verify source.
Route type: derived
2023 source bundle: Chapter 11.2 (2023_BMP_11_2) - Extended Detention Basins (dry detention variant)
2026 source bundle: Chapter 11.2 (2026_BMP_11_2) - Extended Detention Basins (dry detention variant)
Source-basis note: Dry detention is a variant of Extended Detention Basins (Ch. 11.2) with no permanent pool. Not a separate BMP Manual chapter.

Key verified claims already tied to this page manifest: - Dry detention is source-derived from Chapter 11.2 rather than from a standalone chapter. - Dry detention stays a detention-variant concept rather than a separate source authority. - Dry-detention maintenance remains tied to the Chapter 11.2 detention framework.

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: - Dry detention is source-derived from Chapter 11.2 rather than from a standalone chapter. - Dry detention stays a detention-variant concept rather than a separate source authority. - Dry-detention maintenance remains tied to the Chapter 11.2 detention framework.

Siting Constraints¶

The current source-backed siting review should focus on:

whether the design is really a Chapter 11.2 detention variant rather than a mislabeled different BMP
whether site area, access, and outlet control support a detention-basin operating model
whether the page is being used to overstate GI or recharge value that the source basis does not support

Maintenance¶

Maintenance remains detention-centered:

keep basin storage and outlet controls functioning
monitor sediment accumulation and drawdown behavior
treat erosion and access problems as direct operating risks
