Howard County hearing on Bloomingdale Estates conditional-use request highlights traffic, stormwater and historic-site concerns

At a hearing before the Howard County Hearing Examiner, Bloomingdale Estates LLC presented a conditional‑use petition (BA25Dash002C) seeking approval to build 54 age‑restricted units on 16.41 acres off Old Frederick Road. The applicant said the proposal would include semi‑detached and attached units, open space, a community building and pedestrian access to Patapsco State Park; neighbors and nearby property owners testified in opposition, citing traffic, stormwater, specimen‑tree loss and effects on nearby historic resources.

The applicant’s civil engineer, John Carney of Benchmark Engineering, testified that the project would provide 54 units—24 semi‑detached duplexes and 30 attached units—on a 16.41‑acre site with a net developable area of roughly 15.51 acres after steep‑slope reductions. “We are requesting 54 age restricted adult housing units on the 16.41 acres,” Carney said. He told the examiner the proposal yields about 3.5 units per acre under the age‑restricted conditional‑use rules, which allow up to 5 units per acre; Carney said the proposal is “about 30% below the maximum allowable number of units.”

Why it matters: The hearing covered technical and neighborhood impacts that will be evaluated again if the Hearing Examiner grants conditional‑use approval and the applicant proceeds to a site development plan. Several nearby residents testified that existing traffic and drainage conditions are already strained and would be worsened by new development.

Project layout, open space and design

Carney said the plan locates the duplexes along the portion of the site adjacent to Daniels Road and places townhome‑style attached units toward the interior. He said the petitioner proposes about 9.02 acres of open space (roughly 58% of the site), exceeding the 35% minimum for age‑restricted adult housing. The plan includes a 1,382‑square‑foot community building (the county minimum cited in testimony was 1,080 square feet) and walking paths intended to link parts of the subdivision to Patapsco State Park.

Carney described perimeter forest conservation and a Type C landscaped buffer between the proposed lots and adjoining properties on Daniels Road, and said the applicant revised the layout after Design Advisory Panel comments to orient more unit fronts toward Old Frederick Road and to enlarge the community‑building area.

Traffic and sight‑distance evidence

The petition included a 48‑hour speed study and sight‑distance analysis. Carl Wilson, vice president with the Traffic Group, testified that the speed study (collected April 29–30, 2025) found an 80th‑percentile speed of about 38 mph northbound and 36 mph southbound; he said sight distances at the proposed Old Frederick Road access meet the standards used to evaluate safety. Wilson also presented trip‑generation estimates tied to Institute of Transportation Engineers data: about 24 total trips in the morning peak, 27 in the evening peak, and an average daily traffic (ADT) projection of about 351 trips for the 54‑unit site. He testified that those trip counts represent a “relatively low” addition to traffic for a major collector roadway.

Opponents disputed how representative the short speed study is of everyday conditions and cited older traffic counts submitted into the record. Resident Douglas Duvall said traffic is frequently backed up on Old Frederick Road and noted large new subdivisions across the Patapsco River. “If you build this, people are gonna get killed,” he told the examiner during public comment, adding that drivers routinely pass across double yellow lines.

Stormwater, wells and topography

Carney and other project witnesses said stormwater management and water‑quality controls will be designed and reviewed at the site development plan stage; Carney testified the project will meet county stormwater requirements and that no variances to stormwater rules were being sought at the conditional‑use hearing. He described rooftop drainage using dry wells and a drainage study approach that sets a defined study point at the northern site boundary where the stream crosses the line; he also testified that a preliminary analysis showed runoff to a particular adjacent property could decrease because currently grazed pasture will be converted in part to forest conservation.

Several neighbors raised flooding concerns tied to a small stream and an historic spring near the Linwood/Cobb House and asked for a more detailed on‑site geotechnical and drainage review. Kenneth Banks and other nearby property owners described prior episodes of basement flooding and said they wanted stronger assurances about how runoff would be controlled during construction and afterward.

Historic resources and trees

Testimony addressed a historic structure west of the site known in the record as the Linwood House (also referred to as the Cobb House). Carney testified the Linwood House is west of the proposed development and that the closest new structure would be roughly 206 feet from the historic dwelling; he said the plan preserves an 88‑foot‑wide band of forest conservation between the properties and proposes additional plantings in the conservation easement to screen views.

Opponents and the Historic Preservation Commission review recommended retaining the older structure on the Deer Grove parcel; the owner‑developer testified the structure appears in poor condition and is not on the Howard County Register of Historic Places. Janelle Sterner, a Daniels Road resident, said her house and several nearby properties trace to the Linwood estate and that the history and visual character of the area merit preservation. Carney said the house on the Deer Grove parcel is not designated by county resolution as a historic structure.

The petitioners also sought alternative compliance for removal of specimen trees. Carney said there are 31 specimen trees on the parcels; if the plan is approved the applicant would request alternative compliance to remove about 10 specimen trees, and said the petitioner would propose mitigation plantings and that five of the ten were in poor condition. Carney testified the project would plant roughly 387 landscape trees and 31 shrubs in addition to required forest reforestation; he also said mitigation for removed specimen trees would include replacement 3‑inch‑caliper trees as required by county procedures.

Parking, accessibility and housing obligations

Carney testified the proposal includes universal‑design features (zero‑step entries, wider doorways and blocking for grab bars), a first‑floor primary bedroom option, and an obligation to provide moderate‑income housing consistent with county rules (Carney said a 10% obligation would be handled at the site development plan stage). Testimony about parking included potentially confusing interim remarks during the hearing: earlier in direct testimony Carney said “We are proposing a 45” (a reference made during an exchange about spaces serving a particular area); later he identified a total of 145 parking spaces on plan sheets, with about 108 spaces provided on individual lots (two‑car garages and driveways) and smaller off‑street clusters for overflow.

Public comment and positions

Andrew Driessman, a neighbor who spoke in support, said the owners met repeatedly with neighbors before filing, reduced density compared with what the zoning could allow and added buffering and a park path at neighbors’ requests. Dozens of neighbors who opposed the petition described safety and quality‑of‑life concerns: traffic backups and dangerous passing on Old Frederick Road, potential increased runoff and risk to wells and basements during heavy storms, loss of specimen trees, and impacts to the visual setting around historic structures.

Procedure and next steps

No final decision was issued at the hearing. The Hearing Examiner closed the record and said a written decision and order would be issued later. The petitioner may proceed to the required site development plan stage only if the conditional‑use request is approved; site development review would include detailed stormwater engineering, forest‑conservation and transportation compliance reviews.

Quotes

“We are requesting 54 age restricted adult housing units on the 16.41 acres,” John Carney, civil engineer for Benchmark Engineering, told the examiner.

“The trip generation is relatively low for Old Frederick Road,” Carl Wilson, vice president with the Traffic Group, testified of the projected 24 AM and 27 PM peak‑hour trips.

“If you build this, people are gonna get killed,” Douglas Duvall, a Daniels Road resident, said during public comment, describing what he called frequent dangerous passing on Old Frederick Road.

Ending

The Hearing Examiner closed the hearing, saying a decision and order would be rendered in writing. If the examiner grants conditional‑use approval, further technical reviews and permits will be required at the site development plan stage before construction can begin.
