US Army Corps of Engineers: Wetlands determination and delineation procedures for irrigated lands

Wetlands Determination and Delineation Procedures for Irrigated Lands

This provides notice of procedures to be followed in South Pacific Division’s subordinate districts (Albuquerque, San Francisco, Sacramento, and Los Angeles districts) for determining whether, and to what extent, wetlands occurring on irrigated land would persist in the absence of irrigation and meet the definition of wetlands under the 1987 Corps of Engineers (Corps) Wetland Delineation Manual (1987 Manual) and the appropriate regional supplement.

The intent of this process is to improve the accuracy, quality, and consistency of wetland delineations on irrigated land. This process supersedes previous SPD district-specific standards and policies related to delineating irrigated land.

As many wetland delineations are prepared by consultants and provided to districts for verification, consultants are advised to be aware of and follow these procedures when preparing delineations of irrigated land for verification by one of SPD’s subordinate districts.  

This process applies to wetland determinations or delineations made or verified by South Pacific Division (SPD) subordinate Districts on irrigated land.

This includes, but is not limited to, areas in rice production and irrigated pastureland, and is intended solely to address identifying wetlands that would exist absent irrigation. It does not address the jurisdictional status of any such wetlands, issues relative to permitting discharges of dredged or fill material in jurisdictional wetlands, or mitigating impacts to jurisdictional wetlands.

This is consistent with all applicable Corps wetland identification and delineation standards and practices, and with applicable guidance for wetland identification and delineation. Wetland determinations and wetland delineation verifications within SPD are to be conducted in accordance with Corps regulations, guidance, and technical standards.
