Auburn City moves to repopulate streets: 20 trees planned, species mix and contractor oversight debated

Auburn City members discussed a fall 2026 tree-planting plan and maintenance needs at a meeting that focused on replacing failing street trees, species selection and contractor oversight.

Staff said the city has about 20 tree requests for fall 2026 and reported clusters of mortality—particularly red oaks—along Seventh Street and North Main, prompting discussion about whether to replant immediately or allow a gradual transition. "I currently have 20," the staff member said when introducing the item. Committee members recommended wider spacing (about 50–60 feet) for long stretches and a heavier oak mix—red, bur and white oaks—with a small number of maples for fall color.

Committee members and staff also raised concerns about the contractor's recent workmanship. One participant said the most recent installation showed "quite a few discrepancies" compared with an earlier season and suggested meeting the contractor on site and increasing oversight; another suggested placing the contractor on probationary status if problems persist. Members agreed to prepare planting specifications and public notices in the coming weeks so contractors and residents could anticipate the work.

The group discussed practical site constraints. Near a long stretch of walnuts on East Third (about 537 feet), members noted the allelopathic effects of black walnut (jugalone) and said the city would need to choose species compatible with walnut root chemistry. They also flagged a planting date of Nov. 26 and talked about consolidating orders to simplify procurement for contractors.

On maintenance, the meeting set a proactive watering schedule for new plantings with the city water truck starting when temperatures rise. The staff member recommended beginning Monday watering and then Monday/Wednesday each week; for individual homeowners, the guidance cited 5–10 gallons per day for a newly planted tree.

Why it matters: Replacing failing street trees affects public safety, sidewalks and shade coverage over the long term. Members emphasized species diversity, correct spacing and stronger oversight of contractors to avoid repeated mortality and costly replacements.

The meeting also reviewed the city's recommended street-tree palette (discussed in more detail at the meeting) and noted some species to avoid on busy streets. The agenda item concluded with staff preparing specifications and outreach; the committee did not take a binding vote on the planting plan during the session.
