Serving both office/commercial and residential users, the street was lacking in both pedestrian amenities and ADA accessible parking. LORA’s goals for this 1-block section of road also included screening the shopping center directly across the street from single-family residences, add street trees, maximize parking and slow down vehicular traffic. MZLA provided project management, public involvement, landscape architecture and construction support services for this road improvement project. Project components include improved ADA access and parking, a mid-block crossing, street trees, ornamental plantings, brick paver sidewalks, irrigation, new street lighting and green stormwater treatment facilities.
