Irrigation Design Services From an Experienced Landscape Architecture Firm
Evergreen Design Group has a team of in-house Irrigation Design Consultants and Irrigation Designers who create irrigation designs that not only meet the water needs of plants but also conserve water, reduce costs, and promote sustainability.
Types of Landscape Irrigation Systems We Design
We design landscape irrigation solutions for a variety of applications, from small planters to large-scale commercial properties. Our expertise spans several irrigation systems design types, each carefully selected for its efficiency, functionality, and suitability to the landscape.

Drip Irrigation Systems
A drip irrigation system is designed to deliver water slowly and directly to plant root zones, significantly reducing water waste through evaporation or runoff. These systems supply controlled amounts of water to planters, trees, and shrubs.
Our drip systems minimize weed growth, soil erosion, and water-related plant diseases while maximizing water efficiency. We also incorporate pressure-compensating emitters to ensure consistent water delivery regardless of elevation changes.

Green Roof Systems
Our green roof irrigation designs support vegetation on rooftop environments while functioning as effective stormwater management systems. These dual-purpose installations reduce building energy costs, extend roof life, and create valuable green spaces in urban environments.
Green roof solutions are engineered with water conservation in mind. They incorporate moisture sensors and precise control systems to apply water only when required, reducing your water bill while maintaining plant health.
Spray Irrigation Units
Our spray irrigation unit designs provide efficient head-to-head coverage with carefully calculated spray patterns for smaller lawn areas, flower beds, and ground covers. We select appropriate sprinkler heads based on water pressure, area dimensions, and plant water requirements.
Our designs avoid wasteful overspray and ensure uniform distribution, balancing aesthetics with functionality. We carefully zone these systems to accommodate different water needs across your landscape.
Centralized Two-Wire Irrigation Control Systems
For larger or complex sites like corporate campuses, parks, or multi-family developments, our two-wire irrigation control systems offer sophisticated water management. These systems allow for precise irrigation scheduling across numerous zones from a single irrigation controller.
The two-wire technology reduces trenching and wiring costs, enabling advanced features like flow sensing, weather-based adjustments, and remote monitoring. This technology helps save water while simplifying the management of extensive landscape areas.
How Does the Landscape Irrigation Design Process Work?
At Evergreen Design Group, we follow a structured landscape and irrigation design approach, ensuring optimal system performance from planning to installation.
Although we typically follow the same process, no two projects are the exact same. We can customize our approach based on your unique project needs.
Our expert consultants can do the following:
- Soil Assessment and Site Analysis. We start by analyzing soil composition, drainage, available water sources, sun exposure, and existing vegetation. This ensures proper irrigation scheduling, prevents runoff, and optimizes water distribution for plant health.
- Irrigation System Design. Our irrigation designers develop custom, detailed plans that include water lines, spray patterns, and zone layouts. We calculate the water required for each area, ensuring head-to-head coverage while incorporating pressure regulation and backflow prevention.
- Component Selection. We select durable, high-efficiency components like sprinkler heads, irrigation controllers, and drip lines. We can also integrate sustainable technologies and irrigation techniques, like smart controllers or rain sensors, to help your site save more water and lower operating costs.
- Installation Planning. Our team follows a rigorous installation process to increase your irrigation system’s lifespan. Our plans guide trenching, water line placement, and sprinkler system setup. We work closely with contractors to ensure compliance with local regulations and environmental standards.
Why Partner With Evergreen Design Group for Landscape and Irrigation Design?
Our expertise in landscape irrigation design extends beyond system layouts—we provide full-service solutions that keep projects efficient, sustainable, and within your budget.
- Irrigation Plan Prototyping Services. Our team develops prototype irrigation plans, serving as templates for consistent implementation across entire projects. This approach ensures alignment with the client’s vision, prevents inconsistencies, and simplifies project management.
- Integration with Landscape and Tree Disposition Plans. Unlike generic irrigation firms, we design systems with the broader landscape in mind. We integrate landscape and irrigation design from the start to prevent conflicts between tree placement and irrigation infrastructure.
- Expert Guidance on Irrigation Permitting and Compliance. Navigating irrigation regulations can be challenging, but our team ensures compliance with local codes. Where permits are required, such as in California, we assist clients with obtaining approvals, like MWELO compliance.
