West Miami commissioners debate standards for swale and parkway improvements; staff to draft permit package

Staff presented a discussion item on May 13 proposing regulations to allow residents to improve swales and parkway areas within the public right of way where grass is failing and parking activity has compacted soils.

The staff presentation described three primary options: (1) reinforced permeable systems such as turf/"grass-crete" blocks that allow vehicular use while maintaining drainage; (2) concrete perimeter with approved rock; and (3) sod or artificial turf systems that must be permeable. Staff said any approved improvement would require percolation calculations, recorded covenants acknowledging owner-installed work at the owner's risk, and a maintenance obligation that would require the owner to repair or replace improvements affected by city or utility work.

Commissioners raised several concerns. One commissioner said the city must avoid a "kaleidoscope" of different treatments along a block and emphasized aesthetic uniformity. Another urged a threshold so that a minimum percentage remain green (examples cited: 10–25 percent) and asked that permitted materials be FDOT-approved, not construction-site scrap. Cost and equity concerns were also discussed: turf blocks and grass-crete can cost substantially more than simple gravel, and commissioners voiced concern about imposing expensive options on lower-income residents.

The vice mayor said many residents use swales for daily parking and noted that dead grass is itself a code violation; another commissioner suggested administrative approval through a swale-permit package with a menu of approved options so residents would not need to pursue full board hearings. Staff acknowledged existing code-enforcement steps have been used in some cases and reiterated the priority is to preserve drainage and tree canopy while allowing options where grass cannot grow.

Commissioners asked staff to return with a written ordinance/package that includes: precise percolation and maintenance standards, permitted materials and sizes (FDOT-approved), a proposed green-area threshold or criteria-based variance, tree-root setbacks, and enforcement language. The commission directed staff to prepare the draft for consideration at a subsequent meeting.
