Two Arlington subdivisions advancing by right draw resident concerns over trees, traffic and drainage

City planning staff and a developer told District 1 residents that two recent projects in Arlington are proceeding under existing zoning and do not require rezoning or city council approval, prompting questions about notice, tree removal, traffic and stormwater handling.

Erin Abney, chief of current planning, said the Royal Estates (also described as Royal Manor) property is about 4.69 acres and is already zoned RLD 60, a residential low-density designation that carries entitlement for 60-foot-wide lots and minimum lot sizes tied to utility connections. Abney said civil plan review for that site completed in December 2024 and the project is moving forward with site clearing and civil permits. "Because the property is already zoned RLD 60, you're not going to see an orange sign or a bright yellow sign because they're not asking to change their zoning district," Abney said.

David Phillips, land-use counsel for the developer Richmond American Homes, described the Saint Isabelle site as about 18 acres planned for 55 single-family lots at 60 feet wide — roughly 3 units per acre — and likewise permitted by right under existing low-density residential land-use and RLD 60 zoning. "Because the project is consistent with those categorizations, it is permitted by right. In other words, no land use amendment and no rezoning was required to build it," Phillips said. He said clearing and grading were nearly complete and that the developer is saving many trees on the property.

Residents raised several concerns. Multiple commenters asked why notice can be limited when projects are by-right; Abney explained that projects that do not request rezoning do not require the public hearing notice process. Roberta Thomas and other residents cited compatibility with neighborhood character and existing neighborhood action plans, and Abney said those neighborhood plans provide general guidance but cannot override the limits state law places on regulating single-family architectural details; the city may regulate massing, setback and scale but generally not fine architectural elements unless a property is in a designated historic district.

Several residents and speakers asked about tree removal and mitigation. Planning staff said site-work permits and landscape plans allowed the removal and that trees must be mitigated; one staff member said mitigation currently uses a per-inch fee (stated in the meeting as $188 per inch) unless a specimen tree triggers a different rate.

Traffic and emergency access drew repeated questions for Saint Isabelle. Residents questioned the plan for a single ingress/egress and asked whether a traffic study was triggered; planning staff and the developer said traffic studies are required at civil plan review when trip-generation thresholds are met and that staff would check whether Saint Isabelle triggered that requirement and report back to the council member. "What I'm gonna do is I'm gonna check tomorrow about the traffic study and report back to your council member," an official said.

On drainage and flood risk, public-works staff said civil plan review includes flood-risk and drainage review and that subdivisions must retain stormwater on site and release it at pre-development rates via retention ponds. Residents noted local creek and ditch conditions and asked whether the development would increase erosion or send runoff into nearby springs or creeks; staff said retention and engineered release are reviewed during plan review.

Ending: Officials committed to follow up on specific technical questions — including whether a traffic study was required for Saint Isabelle and clarifications about tree mitigation and DEP/environmental permits — and to provide details to the council office and residents.
