“Tree selection for the Valley requires understanding the soil conditions, available space, and microclimate. Sycamore and mulberry trees are beloved for their shade but have aggressive root systems that damage driveways and sewer laterals within 10–15 years of planting. If you want a large shade tree, plant it at the perimeter of the lot, not within 30 feet of any hardscape or structure.”
Request that the landscape designer include underground utility locations (irrigation main line, site lighting conduit, drainage pipe) on a landscape 'as-built' drawing. This document shows where underground utilities are buried, preventing damage from future digging for landscaping changes, pool work, or hardscape modifications.
Most landscape design projects in Project Calabasas that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Project Calabasas creates unpermitted improvement disclosure obligations at sale. Your contractor should pull all required permits before work begins — this protects both your investment and your legal standing.
Verify CSLB license at cslb.ca.gov, request 3+ references from completed landscape design projects in Project Calabasas or nearby, confirm active insurance and worker's comp coverage, and ensure the contractor can explain the permit process for your specific project. Contractors who know Project Calabasas's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
This Calabasas homeowner wanted to replace 3,500 square feet of water-intensive Bermuda grass lawn with a drought-tolerant landscape that would reduce water bills, qualify for LADWP rebates, and complement the home's contemporary Mediterranean architecture.
NP Line Design designed a landscape plan featuring California native and Mediterranean-adapted plants: lavender, rosemary, salvia, agave, kangaroo paw, and ornamental grasses. The design groups plants by water needs (hydrozones) with a Rachio smart irrigation controller managing separate drip zones for each hydrozone.
The existing lawn was removed and the soil was amended with 4 inches of compost tilled into the top 6 inches. Decomposed granite pathways with steel edging wind through the planted areas, creating visual interest and pedestrian access. A dry creek bed with river rock serves both as a design feature and as a swale to manage stormwater runoff from the driveway.
Hardscape elements include a 12x16-foot poured concrete patio with an integral color and broom finish, a built-in concrete fire pit with natural gas connection, and low-voltage LED pathway and uplighting on a timer. All planted areas received 3 inches of bark mulch to suppress weeds and retain moisture. The LADWP Turf Replacement Program rebate application was submitted at project completion — the homeowner qualified for $5.00 per square foot ($17,500 rebate) based on the pre-removal water usage documentation.
The LADWP Turf Replacement rebate requires pre-approval documentation including 12 months of water meter readings, dated photographs of existing turf, and a qualified landscape plan showing plant species and irrigation layout. The homeowner had not started the pre-approval process before contacting NP Line Design, which risked losing the entire $17,500 rebate if turf was removed before LADWP completed their pre-inspection. The rebate program also has specific requirements for minimum plant coverage and irrigation type that must be met at the post-inspection. Additionally, the hillside lot had drainage concerns with water pooling against the foundation during winter rains.
NP Line Design managed the entire LADWP rebate application process from start to finish. We compiled the pre-approval package with water usage records (obtained from LADWP with the homeowner's authorization), site photos with measurements, and our qualified landscape plan — all submitted digitally through LADWP's portal before any work began. LADWP pre-inspection was completed within 2 weeks. For drainage, the dry creek bed swale was engineered with proper slope and rock sizing to handle a 50-year storm event, directing water away from the foundation to a new catch basin at the property line connected to the street. The $17,500 rebate offset 23% of the total project cost.
