Hardscape Contractor in Blackhawk

5.0 on Google · 6 reviews

Blackhawk homes sit on engineered pads at the foot of Mount Diablo, which means clean architectural detail above ground and real slope behind it. Work here is usually a driveway or motor court, a terraced rear yard, and the drainage that protects both — built to a finish level that will pass architectural review.

What we see on local properties

  • Engineered pads and cut-and-fill slopes make wall and drainage design part of the same plan.
  • Wide driveways and motor courts need a base built for vehicle weight, not just appearance.
  • Architectural review means material, colour and layout details are settled before work starts.
  • Hillside runoff above the property is intercepted rather than allowed to reach the pad.
  • Finish detail — cuts, edges, jointing — is what makes the difference on these properties.

Blackhawk permits, HOA review and soil

Permits

  • County, not a cityBlackhawk is unincorporated, so building and grading permits go through Contra Costa County's Department of Conservation and Development rather than the Town of Danville.
  • Retaining wallsWalls over 4 feet (measured from the bottom of the footing) or walls holding back a slope, driveway or structure generally need a permit and engineering. Many Blackhawk lots fall into the second group.
  • Grading and drainageLarger soil moves, work on slopes and any outlet into the street or a storm drain can require county review. Flat-work patios that stay on your lot usually do not.

HOA submittals

  • Architectural review comes firstBlackhawk's homeowners association and its sub-associations review visible exterior changes — driveways, motor courts, walls, patios and grading — before work starts. Approval can take several weeks, so we plan around it.
  • What a submittal usually includesA site plan with dimensions, material and color samples or product sheets (paver style, wall block, cap), drainage notes, and photos of the existing area. We prepare these for you to submit.
  • Gate access and work hoursCrews and deliveries are registered at the gate, and the association sets allowed work hours. We follow those rules on every visit.

Soil notes

  • Hillside clay and engineered padsMany homes sit on graded pads cut into clay hillsides. Clay swells in winter and shrinks in summer, which cracks thin slabs. We over-excavate soft spots and use a deeper compacted base.
  • Water moving downhillSubsurface water travels down the slope and comes out behind walls and patios. Walls get drain rock, filter fabric and a perforated pipe behind them; slopes above a patio may need a cut-off drain.

General information, not legal advice. Rules change and every lot differs — we confirm county, city and HOA requirements for your address as part of the free estimate.

Reputation

“My wife and I recently hired Golden Hills Landscaping for a fence and retaining wall repair project that ultimately evolved into a complete backyard makeover. We could not be happier with the results. Alonso, the owner, was a pleasure to work with from start to finish. He took our general ideas and turned them into a cohesive, functional outdoor design that beautifully complements our property while staying within our budget. The scope of the project included building a 14' x 17' patio area with a gazebo, installing a pressure-treated wood retaining wall, constructing a patio bench seat, landscaping our hillside, and building steps to provide safe access up our steep hill. The craftsmanship and attention to detail throughout the project were outstanding. Alonso and his team were consistently prompt and professional. Whenever unexpected issues arose, Alonso was transparent and communicated clearly about the situation, available options, and any associated costs. We greatly appreciated his honesty and commitment to delivering the highest quality work. My wife and I are thrilled with our new outdoor living space and look forward to enjoying it for years to come. Our only regret is that we didn't undertake this project 20 years ago when we first moved into our home. We are grateful for the opportunity to work with Alonso and the entire Golden Hills Landscaping team and would highly recommend them to anyone considering an outdoor improvement project.”

“We recently replaced our concrete slab backyard with a stone paver patio at our home on Tanager Drive, and Alonso and his crew were fantastic. His quote was higher than others, but he earned the job by being methodical, available, and clearly capable. From the start he was thoughtful about the approach and helped us think through both design and execution. The project moved quickly and efficiently, and his crew was polite, professional, and detail-oriented. Alonso took initiative to fix small details without being asked, which really showed his pride in the work. One of the biggest value adds was his help with planning. He came with me to shop for stone, offered recommendations, and ultimately improved our original vision. The yard went from concrete to castle. The finished patio looks amazing and is one of our favorite spaces. I strongly recommend Alonso and his crew for any landscaping, yard work, or exterior renovation. Very grateful for his work and would absolutely hire him again.”

“Had a great experience with Golden Hills Landscape. They installed pavers, irrigation, rocks, and sod in my backyard and did a fantastic job. Super professional, great prep work, and everything was done in a timely manner. Pricing was very fair. The yard looks amazing--would definitely use them again and highly recommend.”
