Parkway Planting

New single-family homes and custom homes in Murrieta must plant one 24-inch-box street tree every 40 feet on center in the parkway strip between the curb and the front of the structure, plus two 15-gallon shade trees on the lot, three on corner lots, under Development Code Section 16.28.070(C)(2). An automatic irrigation system is required for the same area.

The Community Development Director enforces compliance through site inspections authorized by Section 16.28.050(D) and can withhold release of the one-year landscape performance security if the required street trees and shrubs were not installed or maintained. Failure to comply with a Murrieta ordinance is otherwise handled as a general infraction under Section 1.08.050: fines run $100 for a first conviction, $200 for a second within a year, and $500 for a third or later, with repeat or serious violations chargeable as a misdemeanor punishable by up to $1,000 and six months in county jail.

Heritage & Protected Trees

Murrieta protects trees the city council formally designates by resolution as historically significant, whether for their tie to a notable event or person or for their size, condition, or aesthetic value, under Municipal Code Sections 16.42.040(F) and 16.42.050(D).
