Commission backs changes to TDR ordinance and lowers TIA thresholds to allow MDP review before rights transfer

The Planning Commission on Sept. 3 recommended approval of an amendment to Chapter 165 of the county zoning ordinance to clarify and modernize the Transfer of Development Rights (TDR) program.

Staff summarized program mechanics, noting about 780 rights have been severed to date and that the program has helped preserve roughly 6,000 acres. The proposed ordinance changes would explicitly tie receiving-area eligibility to specific residential zoning districts (RA, RP, R4), allow master development plans (MDP) to be submitted and processed before rights are transferred (with approval contingent on the transfer), and require receiving developments to implement area-plan standards such as rights-of-way and trail systems.

Pearson also proposed updates to the county's Traffic Impact Analysis (TIA) standards, lowering the practical threshold so the county can require TIAs for by-right residential projects expected to generate 100 or more residential vehicle trips in a peak hour (or 250+ peak-hour vehicle trips) rather than relying solely on older, VDOT-based daily-trip thresholds that effectively applied only to rezonings.

Commissioners asked detailed questions about how rights are certified and severed, tax/assessment treatment of severed (floating) rights, how the program affects family subdivisions and retained rights, and whether limiting language is needed to prevent speculative purchases that developers cannot implement. Staff responded that severance is recorded by deed and that certificates remain valid unless zoning changes; staff also noted the ordinance includes waiver authority and will allow staff review to avoid inappropriate TIA requirements for marginal projects.

After discussion the commission voted to recommend the ordinance and associated policy updates to the Board of Supervisors; one commissioner recorded an abstention on procedural grounds while a majority voted in favor. The Board is scheduled to receive the commission's recommendation on Sept. 24.

What changed: Key modifications to the TDR program are (1) explicit receiving-area zoning criteria, (2) ability to process MDPs before rights transfer (contingent on transfer), and (3) revised TIA thresholds so traffic analysis can apply to by-right development when warranted.

Implementation: Staff said site-plan review and master-development-plan processes will address details such as whether planned roads and trail connections are required; financial and tax implications for property owners who sever rights will be handled through recording and assessment practices and may affect appraised/assessed values.
