New Paver Patio and Drainage, Ladera Ranch

Overview

A Ladera Ranch backyard with patchy grass and poor drainage got a new paver patio, a 31-linear-foot segmental retaining wall, and a French drain tied into the existing system. Work wrapped in roughly three weeks on site.

Quick Facts

Neighborhood (92694)

Constraints/Challenges The side yard grade required a 36-inch-tall segmental retaining wall along a 31-linear-foot run to hold the bank and give the patio a clean edge. Drainage had to connect cleanly into the property's existing drain system without disturbing the adjacent wall. A single mid-project rain day was sequenced around without affecting the overall build order.

Goals The homeowner wanted a usable, low-maintenance backyard surface to replace patchy, dying grass and address standing water near the house. A retaining wall was needed to define the yard and support the grade.

Scope Interlocking paver patio (modular ashlar pattern), 31 LF segmental retaining wall with AB Europa 8x18 Dover block and AB Capstone cap, French drain with Schedule 40 PVC tied to existing system, downspout connection

Style Transitional

Timeline Roughly 3 weeks on site from site setup through closeout.

Price Range $28k-$31k

The Challenge

  • The backyard had patchy, dying grass and large areas of bare soil, making it difficult for the household to use the space comfortably.
  • Surface water had no clear path away from the house, increasing the risk of water pooling near the foundation after rain.
  • The existing grade dropped unevenly along the yard boundary, leaving the area prone to soil erosion without a wall to hold it.

How Install It Direct Helped

The homeowner needed a backyard that could actually be used year-round, without mud, erosion, or water collecting near the house. Install It Direct built a paver patio in a modular ashlar pattern using ORCO pavers, backed by a 31-linear-foot retaining wall in AB Europa Dover block with capstone to hold the grade. A French drain with Schedule 40 PVC pipe tied into the existing drain system pulls surface water away from the foundation. Now the yard has a solid, flat surface the household can walk on the day after rain without tracking mud inside.

Market Context

Backyard paver patio and retaining wall projects in South Orange County and North San Diego typically run $25,000-$40,000 when drainage work and a structural wall are part of the same scope.

Neighborhood Context

Ladera Ranch is a master-planned community in South Orange County where typical backyard lots sit behind stepped grades that often require retaining walls and active drainage to make the usable area flat and dry.

Over 1,000 five-star reviews and 1,500+ San Diego homeowners served.

The Plan

Project plan
  • Paver layout designed in a multi-size modular ashlar pattern using ORCO Block and Hardscape 60mm Villa Express pavers for visual texture and durability
  • ORCO 60mm Holland charcoal accent pavers incorporated for contrast within the field pattern
  • 31-linear-foot segmental retaining wall specified at 36 inches height using AB Europa 8x18 Dover block with AB Capstone wall cap for a finished top edge
  • French drain system routed with Schedule 40 PVC pipe, joined with Oatey PVC Primer and Cement, tied into the property's existing drain system
  • Downspout connection added to route roof runoff directly into the new drain line
  • Class II aggregate base compacted to subgrade per ICPI spec before screeding 1-inch bedding sand layer; drainage slope set to meet minimum away from the foundation

The Build

Dig Alert clearance and scope marking completed at the start of the build. Crew stripped the backyard to subgrade, excavated wall and drain trenches, and established string lines for grade control.

AB Europa Dover block courses were set in the trench with geotextile fabric behind the wall face and perforated drain pipe laid at the footing. Schedule 40 PVC drain lines were run and connected to the existing system, with a downspout tie-in added before backfill.

Aggregate base was spread and plate-compacted to grade. Bedding sand was screeded to a uniform 1-inch depth across the patio footprint, with slope verified away from the house.

ORCO Villa Express and Holland charcoal pavers were set in the ashlar pattern, cut to fit at edges. Joints were sanded, and the AB Capstone cap was set on the wall. A vinyl gate was installed between wall sections to complete the yard enclosure.

The Result

The project replaced a patchy, eroding backyard with a solid paver patio in an ashlar pattern backed by a 31-linear-foot, 36-inch-tall segmental retaining wall. A new French drain tied to the existing system now moves surface water away from the foundation after every rain event.
Sloped residential backyard with a segmental concrete retaining wall and vinyl fence; the yard subgrade is bare soil covered with erosion-control straw/mulch and looks prepared for future landscape or hardscape work. Small potted plants sit against the house exterior at the left, and there are no pavers or turf installed yet.

Pavers: ORCO Block and Hardscape 60mm Villa Express (primary field), ORCO 60mm Holland charcoal (accent). Retaining wall: AB Europa 8×18 Dover block, AB Capstone wall cap, 31 linear feet at 36 inches height. Drain pipe: Schedule 40 PVC with Oatey PVC Primer and Oatey PVC Cement. Geotextile fabric behind wall face. Base: Class II aggregate road base, compacted per ICPI spec. Bedding sand: 1-inch screeded layer. Vinyl gate installed between wall sections.

French drain installed at the wall footing with perforated pipe wrapped in geotextile fabric. Schedule 40 PVC solid line connects to the property’s existing drain outlet. The downspout was tied directly into the new line so roof runoff moves into the drain instead of sheeting across the patio. Patio surface slope was set to drain away from the foundation.

Roughly three weeks on site. Site prep, Dig Alert clearance, and scope marking led off. The wall, drain trench, and downspout connection followed, then aggregate base and bedding sand. Pavers were set in the ashlar pattern and compacted, joints were sanded, and the final walk-through closed the job.

Frequently Asked Questions

A project like this one in Ladera Ranch 92694 — paver patio, a 31-linear-foot segmental retaining wall, and a French drain tied to the existing system — ran in the $26,000 to $32,000 range. Cost drivers include wall height, drain complexity, and patio size. A shorter wall or a smaller paved area would reduce the total.

Most South Orange County paver-and-wall projects of this scale run roughly 3 to 5 weeks on site depending on access, drainage complexity, and weather. On a backyard build with one structural wall, active drainage, and a modest paver footprint, 3 weeks is typical once materials are staged.

Permit rules vary by jurisdiction, but as a general rule in Southern California a retaining wall over 3 feet tall measured from top of footing triggers a building permit. This wall was 36 inches, right at the threshold. For any wall at or above 3 feet — or any wall that will support a surcharge like a driveway or pool deck — confirm requirements with the local building department before construction.

The crew installed ORCO Block and Hardscape 60mm Villa Express pavers as the primary field material, with ORCO 60mm Holland charcoal pavers as an accent. Both are laid in a multi-size modular ashlar pattern for a varied, traditional look. ORCO is a regional supplier well-suited to the South Orange County climate.

A perforated pipe is laid at the base of the retaining wall and wrapped in geotextile fabric to keep soil out. Schedule 40 PVC solid pipe carries collected water to the property's existing drain outlet. A downspout from the roofline was also tied into the new line so roof runoff goes directly into the drain rather than sheeting across the patio or pooling near the foundation.

Concrete pavers take minimal upkeep. Sweep or blow off debris regularly. Re-apply polymeric sand to the joints every few years if erosion or ant activity opens gaps. A penetrating sealer can be applied every two to four years to reduce staining if you want extra protection. The AB Europa retaining wall block is effectively maintenance-free once installed.
