Planning staff outlines county water resources element; commission debates growth, density and infrastructure trade-offs

Planning staff presented an overview of the county’s Water Resources Element and discussed implications for Taneytown’s comprehensive plan, focusing on potable water supply, wastewater capacity, inflow-and-infiltration (I&I) reduction and regional reuse alternatives.

The staff presentation explained that the county planning department’s analysis concluded there is enough water in Carroll County, in theory, to support the planned growth reflected in municipal comprehensive plans. “After all the number crunching, the county planning department has determined that, you know, there is there is adequate water within Carroll County to support the planned growth,” planning staff said. The presentation cautioned that developing new sources — reservoirs or additional wells — and permitting remain practical challenges.

Staff summarized short- and long-term strategies: protecting existing drinking water and wellhead areas; identifying new supplies for planned growth without overallocating; pursuing I&I reductions in sewer collection to free capacity; and monitoring emerging wastewater reuse technology illustrated by Westminster’s indirect potable reuse pilot. The presentation noted that Westminster’s pilot used membrane technology and would return treated water to the Cranberry Reservoir because state rules currently disallow direct potable reuse. Planning staff said that while technology exists, higher treatment costs and nutrient-permitting limits will shape future municipal choices.

For Taneytown specifically, staff described that buildout calculations draw on a buildable land inventory and zoning assumptions; the county slide deck showed the additional wastewater capacity that would be needed to support ultimate buildout for the collectively mapped sewer service area (an additional 121,832 gallons per day was cited on one slide). Staff also reported ongoing sewer system work to address inflow and infiltration and said a manhole rehabilitation project for the main interceptor has been signed off for design to reduce stormwater inflow.

Commissioners debated growth-area designation, density and the community’s survey results. Several commissioners said they perceived a mismatch between public survey responses favoring lower-density, single-family development and draft plan text that they felt emphasized higher-density or townhouse-style options. Commission members asked staff to ensure property owners in identified growth areas have an opportunity to comment — including owners who may wish to pursue agricultural preservation rather than development — before the commission finalizes plan recommendations.

A resident, Chris Tillman, addressed the commission to clarify how density rules would affect unit counts under a community-village overlay. “When you talk about density… in terms of number of units, that doesn't change,” Tillman said, explaining that many design options concentrate units on part of a parcel but do not necessarily increase the total number of dwellings that a site’s zoning allows.

Staff said the Water Resources Element is lengthy and that they would provide the full document to commission members to review over subsequent meetings. They also noted that some county numbers predate recent local projects and that more recent figures have been supplied to Arrow (the county consultant) after the element’s data cutoff; the commission was urged to consider both the county element and town-specific clarifications when drafting Taneytown’s final plan.

No formal commission votes were taken on the element or on comprehensive plan modifications at this meeting. Staff and commissioners agreed to continue the comprehensive plan discussion in future meetings and to solicit property owner input where appropriate.
