The Yards We Fix
Hillside and Landscape Issues in Altadena? Expert Help Available
Most projects we build start from one of these four situations. Recognizing yours is usually the first step toward a real design.
Overgrown or Outdated
A yard that has drifted past tidy maintenance and needs a real overhaul: design, hardscape, and planting in one coordinated build.
Thirsty Lawn, High Bills
Water-intensive grass that costs more every drought year. Hydrozoned drought-tolerant design with rebate-qualified palettes pays itself back.
Sloped or Hillside Lot
A grade that demands real engineering: terracing, retaining walls, drainage. Most firms send hillside work out. We build it.
Permit-Heavy Project
Hardscape over the impermeable threshold, retaining walls over four feet, driveway widening. Pasadena B&S and LADBS familiarity built in.

Client Voice
What Our Customers Say
Selected feedback from Pasadena, Glendale, La Cañada, and Beverly Hills clients across the last two years.
"We replaced our front lawn with a California native landscape and Belgard paver walkway. The team explained the rebate process, helped us file, and the install was clean. Five stars."
"Built our outdoor kitchen and pergola last summer in La Cañada. Crew was respectful, the PM sent photo updates while we traveled, and the design integration with our existing patio is beautiful."
Local Expertise
Our Landscape Expertise in Altadena
Altadena is unincorporated LA County territory in the foothills above Pasadena, with hillside lots, fire-zone requirements, and LA County Public Works permitting instead of a city process. Properties along Foothill Boulevard and in Janes Village carry significant slope conditions that need proper engineering.
Fire-zone compliance is central to landscape design here. We use fire-resistant California native species with defensible-space spacing and design drainage systems sized for foothill storm events, integrating them with retaining walls and hardscape to stabilize slopes through wet seasons.
Christmas Tree Lane and the residential streets north of the 210 sit in a mix of hillside and flat terrain. Our Pasadena headquarters is 10 minutes down the I-210, making same-week site visits straightforward.

Common Questions
Altadena Landscape Contractor Questions
Do you handle LA County permits in Altadena?
Yes. Because Altadena is unincorporated, hardscape and retaining wall permits go through LA County rather than a city. We handle that submittal in-house.
Can you do fire-wise hillside design in Altadena?
Yes. Fire-wise plant palettes, defensible spacing, and hillside drought design are core work for our foothill projects. We design to LA County Fire's brush-clearance requirements.
Do you do paver patio and driveway work in Altadena?
Yes. Standard hardscape scopes, paver patios, paver driveways, and driveway widening, are available here. LA County Building & Safety handles permits rather than a city department, and we submit those applications in-house.
Still have questions? Get in touch and we'll talk it through.
