Adopted Amendments to the Public Facilities Manual (PFM) Regarding Sanitary Sewer and Editorial and Minor Changes

On April 14, 2026, the Board of Supervisors (Board) adopted miscellaneous amendments to the Public Facilities Manual. The amendments became effective at 12:01 a.m. on April 15, 2026.

The proposed sanitary sewer amendment updates Table 10.1 by reducing the recommended sewer design flow rates for single-family detached, multi-family, and office development and adding design flow rates for commercial and medical uses. The amendment also reduces the peaking factors for existing sewers and incorporates the peaking factors into the PFM in both graphic and tabular format for ease of use as shown in Plates 1-10 (Peak Flow Curve) and 2-10 (Peak Flow Chart).

The minor and editorial amendments include: 1) updating miscellaneous provisions to align with recent updates to the Erosion and Stormwater Ordinance (County Code Chapter 124.1) and the Virgina Stormwater Handbook, 2) incorporating the stacked townhouse unit to align with the Zoning Ordinance (County Code Chapter 112.1), 3) updating Plate 20-7 related to the construction of driveway entrances along existing streets to align with Virginia Department of Transportation (VDOT) standards, and 4) codifying current processes including showing the sump pump discharge locations on the plan for single-family detached developments.
