Buried among six routine zoning amendments the Calvert County Planning Commission advanced Tuesday night is a change that cuts one of the county’s environmental protections for land along the Chesapeake Bay: how much replanting property owners must do after clearing trees in the Critical Area.
Under Calvert’s current zoning ordinance, clearing more than 30% of natural vegetation on a lot in a Critical Area Limited Development Area (LDA) requires a variance from the county’s Board of Appeals — and, if granted, replanting three times the area cleared. Text Amendment 2627, approved unanimously by the Planning Commission and now headed to the Board of County Commissioners, creates a new middle tier: clearing between 30% and 50% of a lot’s vegetation in an LDA or LDA3 zone would require only double, not triple, replanting — and would no longer need Board of Appeals approval at all, as long as the clearing is limited to “the minimum amount necessary” for a house, deck, patio, driveway, septic system and a small yard.
“Staff believes the current replacement planting requirement is too burdensome for property owners, and the costs of meeting this requirement can get quite excessive,” a Calvert Planning & Zoning staffer told commissioners, adding that the department “was able to get buy-in from the critical area commission to relax these requirements in these specific circumstances in order to lower the financial burden on property owners.”
No commissioners raised concerns about the environmental trade-off during Tuesday’s hearing, and no members of the public signed up to speak on the amendment — a pattern that held across all six items on the night’s agenda. The commission voted to close the record and recommend adoption without discussion.
The Chesapeake Bay Critical Area — the band of land within 1,000 feet of tidal waters and wetlands — is regulated jointly by local governments and the state’s Critical Area Commission for the Chesapeake and Atlantic Coastal Bays, which reviews local zoning changes affecting the Critical Area as part of each county’s state-approved program. It is not yet clear from Tuesday’s hearing whether the state commission has formally signed off on this specific change or has only been briefed on it informally; a local text amendment altering Critical Area standards still requires that state review before it can take effect, separate from the county commissioners’ vote.
The amendment is one of six the planning commission is sending to the Board of County Commissioners from a comprehensive zoning ordinance rewrite that took effect in March 2025, with follow-up amendments already made in September 2025 and July 2026. County officials have described most of this year’s fixes as corrections to gaps or unintended consequences from that rewrite — but TA 2627 stands out as a substantive rollback of an environmental standard rather than a technical correction, at a time when Calvert is also weighing how much growth its “small, rural peninsula” can absorb.
A date for the Board of County Commissioners’ hearing had not been set as of the Planning Commission’s vote.
