A yard with a clear plan.

“We want a low-water back yard that’s safe for our dog, with a place to eat outside for the four of us. Keep the lemon tree. No lawn. We’d like to stay under $35k all-in.”

02 / Your brief, traced through the design

The priorities that shaped it.

Low water

Addressed

All 7 species rated low or very-low water (WUCOLS, south coastal). Lawn replaced by mulched beds on drip with a weather-based controller.

Plan & schedule

Plant schedule, Water column; design check “All species low/very-low water”; budget lines “Drip irrigation conversion” and “smart controller”.

In the renders

Hero + aerial: no lawn, mulch visible between plants.

Pet-safe for a dog

Addressed

None of the 7 species is on the ASPCA list of plants toxic to dogs; lavender and yarrow are deliberately left out. Soft grasses and fuchsia edge the path, nothing thorny.

Plan & schedule

Plant schedule note; design check “No ASPCA-listed toxic species” (each species checked against the ASPCA list).

In the renders

No lavender, agave or thorny plants in any view.

A place to eat outside for 4

Addressed

168 sf (14 × 12 ft) paver patio right outside the sliding door. A 48-inch round table with 4 chairs needs roughly 10 × 10 ft [estimate], so there is room to pull chairs out and walk past.

Plan & schedule

Plan: PORCELAIN PAVER PATIO, dimensioned 14'-0" × 12'-0".

In the renders

Door view and hero: table for 4 on the patio. The dining set itself is not in the budget (you supply it).

Every request in the brief is traced to the plan, the plant schedule and the renders. The plan is the reference for exact layout.

02 / Your brief, traced through the design

The details. And the tradeoffs.

Keep the lemon tree

Addressed

Lemon kept in place with a 3.5 ft mulch-only ring around the trunk; the trunk-protection area stays clear; planting near the canopy follows the sun-per-zone check.

Plan & schedule

Plan: EXISTING LEMON (keep) · mulch ring; design checks “No planting within 3.5 ft of lemon trunk” and “Sun per zone”.

In the renders

Hero and aerial: lemon kept at the left; door view: on the right.

No lawn

Addressed

All existing turf (~1,431 sf) comes out and becomes planted, mulched beds (1,413 sf), patio and DG path. Rebate eligibility still requires program review and pre-approval.

Plan & schedule

Plan: no lawn hatch anywhere; budget line “Remove lawn/sod”.

In the renders

All three views: no lawn.

Budget under $35k

Tradeoff · low end fits

Contractor-installed range $23.6k–46.3k, including a 10–15% contingency. The low end is inside $35k; the high end is not. After the LADWP rebate ($7.2k–8.6k) the net range is about $15.0k–39.2k. Skipping the optional phase 3 path lights saves $1.1k–2.0k, and DIY-ing the ✓ lines lowers it further (phasing table).

Plan & schedule

Install budget (pages 16–17) and phasing options (page 18).

Think year three. Renders show planting about 3 years after install. One-gallon plants are roughly 8–12 inches across at install; expect 2–3 growing seasons for the beds to fill in.

Read the renders with the plan. Renders show the look: materials, planting and how the space feels. The concept plan on page 07 is the reference for exact layout, plant positions and the bench landing at the end of the path.

05 / The thinking behind the layout

A place for everything.
A reason for each choice.

01
Plants follow the sun. With the yard on the north side of the house [assumed], the house shades the first ~8 ft from the wall, and the lemon shades the ground under it. Only coffeeberry and California fescue, which take part shade, go there. Sun-lovers (sage, buckwheat, deer grass, fuchsia, California lilac) fill the open middle and the back fence, which get full sun. A design check confirms this for every plant.
02
The path goes somewhere. It leaves the patio, swings around the sage beds and ends at a 6 × 6 ft landing with a bench against the back fence, framed by two pairs of California lilac (deep blue in spring). From the sliding door your eye travels down the path to the bench. From the bench you look back at the house over the beds.
03
Low water by design. Seven low or very-low water natives replace the lawn, on drip with a weather-based controller. The plants are grouped by water need, so the California lilacs can come off irrigation once established (see section 6).
04
Low maintenance. Plants are spaced at their mature width in drifts of 3–5, so nothing needs shearing to fit. Upkeep is one cut-back a year for the grasses and perennials, plus topping up the mulch. Stabilized DG and pavers mean no mowing and no edging of turf.
05
Dog-friendly. No species on the ASPCA list of plants toxic to dogs; soft grasses and fuchsia along the path edges instead of anything spiny. The patio and path give the dog firm, mud-free routes. The side gate stays clear.
06
Rebate requirements considered. The rebate estimate includes an extra $1/sf for an all-native plant list, and the stormwater feature the program requires is in the budget. Apply for pre-approval before any grass comes out.

08 / Getting established

Plant for the season you’re in.

When to plant

Plant from late October through February, ideally November to January, after the first rains. Cool temperatures and short days reduce transplant stress, and winter rain does part of the watering. California lilac (Ceanothus) in particular should go in during fall or early winter: it is prone to disease if watered through its first summer. If the install slips to spring, plant the grasses, sage and fuchsia first and hold the California lilacs until fall.

On planting day

  • Remove the lawn and weeds first. If time allows, water the bare soil once and pull whatever re-sprouts before planting.
  • No soil amendments, compost or fertilizer, and no tilling. Natives prefer lean native soil.
  • Soak the pots the day before. Dig each hole twice as wide as the pot, fill it with water and let it drain, then set the plant with the top of the rootball ¼–½ inch above grade.
  • Spread 3 inches of bark mulch between plants, keeping it 2–3 inches clear of every stem and crown. Mulch touching stems invites rot.

Path & Plant / Sample residenceWatering guide / 13

08 / Your first-year care guide

Water the soil.
Read what it needs.

Year 1 (establishment)

Water by soil moisture, not the calendar. At least twice a week, check 3–4 inches down with a trowel or finger. If it's dry, soak deeply: about 3–4 gallons per 1-gallon plant, so the whole rootball and surrounding soil are wet. In practice that is often one deep soak every 7–10 days in dry weather. Don't let the rootball dry out completely. Light winter rain doesn't soak deep, so supplement during dry spells, and set the controller to manual in winter.

Year 2 onward

Low-water natives (most of this list): a deep soak every 2–3 weeks in summer, or less. Water on cool mornings, not during heat waves. California lilac: no summer irrigation once established. Cap or plug its drip emitters after the first year. California fuchsia looks best with a deep summer watering every couple of weeks. Move drip emitters outward as plants grow, away from the crowns.

Mulch and weeds

Keep 3 inches of mulch on all beds until the plants fill in, topping it up each fall and always keeping it off the stems. Pull weeds while they are small during the first winter and spring. That is when they compete most with new plants.

Watering amounts are guidance for this site’s assumed conditions. Soil, rainfall and plant condition govern actual watering; confirm the irrigation design with your contractor.

Path & Plant / Sample residenceMaintenance guide / 14

08 / A lighter maintenance rhythm

A little care.
Room to grow.

  • California fuchsia: cut back hard, to 1–2 inches, in late fall or early winter once it looks ragged.
  • Deer grass: cut back in fall only if it looks untidy; otherwise comb out the dead blades.
  • Purple sage 'Point Sal': trim the spent flower stems in late fall for a good spring flush.
  • California buckwheat: tolerates hard pruning; cut back the dry flower heads in fall or leave them for birds.
  • California lilac and coffeeberry: no routine pruning. They are spaced to reach full size without shearing. Light tip-trimming of California lilac, if needed, is best done right after spring bloom.

A practical sequence.

Contractor-installed

$23.6k–$46.3k

Before any potential rebate. Includes optional lighting and contingency.

$35k target / Tradeoff: the low end fits

Ask contractors to price the complete scope first. Then compare phasing and owner work. Dropping the optional lighting saves $1.1k–2.0k.

PhaseContractorIf you DIY the ✓ items
Phase 1: Hardscape: slab removal, patio, path, bench landing$11.6k–20.8k$9.6k–17.0k
Phase 2: Irrigation + planting$8.8k–17.5k$6.0k–11.9k
Phase 3: Lighting (optional)$1.1k–2.0k$1.1k–2.0k

Phase totals exclude contingency. The DIY scenario assumes owner work at 35% of the corresponding installed line costs; it is a planning estimate, not a quote. The sod-cutter rental is a separate allowance of $90–150, outside contractor totals.

Potential turf rebate / Estimate

$7.2k–$8.6k

Estimated at LADWP’s $5/sf, plus $1/sf for an all-native plant list, on 1,431 sf. Program rates and rules change, so apply for approval before any lawn comes out and confirm the stormwater requirement. Don’t count a rebate as committed funds until it is approved.

Optional material swap / Concrete pavers

24 × 24 in concrete pavers on the same base can replace the porcelain: $3,360–$5,040 for 168 sf. This replaces the porcelain line; it is not added to the total. Reprice with your contractor.

12 / The contractor packet

One scope.
Three comparable quotes.

Send this scope, the concept plan, plant schedule and quantity schedule to three local landscape contractors. You choose, hire and pay them directly. We take no fee from contractors.

  1. Remove the existing ~180 sf concrete slab and haul it away. Remove the lawn across ~1,431 sf. No regrading; keep the existing drainage pattern.
  2. Install a 14' × 12' porcelain-paver patio on a compacted base at the sliding door, flush with the existing threshold step.
  3. Install a 4' wide stabilized-DG path from the patio to a 6' × 6' stabilized-DG landing at the back fence per the plan, with steel edging on both sides of the path and three sides of the landing. Set the owner-supplied (or contractor-supplied, if quoted) 5' bench level on the landing.
  4. Convert irrigation to drip with a weather-based smart controller. Contractor designs the hydraulics and pulls any plumbing permit (backflow).
  5. Add a stormwater retention feature (downspout to a dry swale or bed), required for the turf rebate.
  6. Supply and plant per the plant schedule (quantities and container sizes), with 3" bark mulch and 4 boulders as located.
  7. Optional: 4 low-voltage path lights (licensed electrician).
  8. Please quote each line separately, with the timeline, the warranty on plants, and your CSLB license number.
Confirm the bench in the quote. The budget includes a contractor-supplied teak bench ($650–1,000). If you’d rather supply your own, say so, and ask each contractor to state clearly whether the bench is included.

14 / Before this becomes a build

A concept to discuss.
A few things to confirm.

Before installation

  1. Use your revisions. Two rounds are included: move, swap or cut anything that doesn’t feel right.
  2. Confirm the real site. Verify dimensions, sun, setbacks, access and existing drainage on site.
  3. Buy to the schedule. Match species, cultivars and container sizes. If a nursery offers a substitute, check it against the same rules: sun, water and pet safety.
  4. Resolve the budget. Compare three itemized bids, confirm the bench supplier, phasing and any rebate approval.

The work this concept does not cover

Design intent only, not construction documents. Grading, drainage, retaining walls and structures, irrigation hydraulics, electrical and gas work must be designed and performed by licensed professionals. Verify all dimensions on site.
