Description of Proposed Guidance Document Changes

There were several general goals with the V1.2 revisions. One was to correct known errors or typos, such as incorrect regulatory citations, mathematical signs in certain equations, grammar, spelling, and internal cross-references and web links. Revisions also make the VSMH consistent with amendments to the Virginia Erosion and Stormwater Management (VESM) Regulation, 9VAC25-875, effective August 14, 2025, and agency guidance documents that have become effective since V1.1 went into effect. Other revisions include modifications to the construction BMPs to reflect industry standards for materials and revising inspection frequencies to be consistent with the Construction General Permit (9VAC25880). The V1.1 waterbar specification, C-ECM-08, was divided into two separate specifications: C-BMP-08 is the Temporary Waterbar specification; and C-ECM-17, the Permanent Waterbar, which is a new specification and includes the conversion from temporary to permanent. Planting schedules and lists were also corrected and revised to remove invasive species, add more native species, and refer to the most up-to-date published plant lists which are frequently revised based on new information. A summary of revisions and a .pdf of Version 1.2 with underline and strikethrough to show inserted and deleted text will be available under the “Virginia Stormwater Management Handbook, Version 1.2” banner on the DEQ website at: https://www.deq.virginia.gov/water/stormwater/stormwater-construction/handbooks .
