Planning commission adopts street and pedestrian standard changes to reduce maintenance, shift bike lanes off-street
Summary
The commission voted to adopt amendments to subdivision regulations (article 4-103) that narrow travel lanes from 12 to 11 feet, move bike lanes to off-street 10-foot shared-use paths in many cross-sections, and remove some grass strips to reduce maintenance and increase safety; commissioners debated tradeoffs and emergency access concerns.
The Mount Juliet Planning Commission on May 21 approved a comprehensive amendment to subdivision street and pedestrian standards (article 4-103) aimed at lowering long‑term maintenance costs and improving multimodal safety.
Key changes approved: Public works recommended reducing standard lane widths from 12 to 11 feet, lowering posted/design speeds for many street categories, and shifting on‑street bike lanes in several typical sections to off‑street 10‑foot shared‑use paths adjacent to the sidewalk. The amendment also removes the grass strip between curb and sidewalk in several collector and arterial cross‑sections — widening the usable sidewalk/pedestrian zone and reallocating road width toward bike-lane buffers and pedestrian space.
Rationale and debate: Todd (public works) said the changes align the code with recent PUD practice and would reduce maintenance burdens. Commissioner Rass (civil engineer background) supported moving cyclists to a shared path on residential collectors for safety but warned that removing green buffers could place pedestrians nearer to vehicles. Some commissioners and public commenters raised concerns about emergency vehicle access, the need for vertical separation or protected bike lanes on higher‑speed roads, and the appearance a concrete median-only cross-section could create. Several commissioners urged flexibility: allow concrete curb-adjacent shared-use paths for many new projects while preserving landscaped medians at key entry or signature locations.
Safety and maintenance trade-offs: Police and former public-safety staff noted maintenance crews’ safety and budget constraints as reasons to reduce grass-strip mileage. The city’s bicycle‑pedestrian advisory committee supported the compromise cross-sections. Staff cautioned that federally funded or TDOT projects may still require grass strips under grant conditions; those projects would be coordinated with TDOT standards.
Outcome: After discussion and public comment, the board approved the amendment by voice vote. Commissioners indicated staff would retain flexibility to require landscaped or signature treatments at specific intersections or entrance points and to coordinate with TDOT on grant-funded corridors.
Representative quotation: Commissioner Rass said, “Putting bicyclists up on some type of a path…is a great idea,” while noting that “removing that grass buffer is just a safety issue for me” in certain contexts. Todd replied that the amendment codifies practices staff has been applying to recent PUDs and that the change is intended for new construction rather than retrofitting older neighborhoods.
Next steps: The subdivision regulation amendment is a final decision at the planning commission; implementation details will be embedded in engineering reviews and future subdivision approvals. Staff will coordinate exceptions for TDOT or grant-required sections.
