Project Overview

Clement Walsh Landscape Architect, Inc., was approached to create a complete permit set for a new fast-food restaurant that met local jurisdictional requirements. The project manager contacted us with the initial conceptual site plan, soil geotechnical report, and pre-application meeting notes. From this information, our own code research, and collaboration with architects, developers, civil engineers, and ecologists, we developed a comprehensive plan set that satisfied jurisdictional code requirements and climatic constraints. The curated planting palette emphasized durability, low maintenance, and cost-efficiency while creating a cohesive, clearly legible landscape composition that reinforces circulation patterns, highlights key entries and signage, and supports the building’s architectural presence.

The Challenge

This project required an expert balance of code requirements, budget, maintenance, and overall aesthetic for a successful landscape. City and county landscape codes required strict quantitative plant metrics to be met, including minimum street tree spacing, perimeter buffering requirements, parking lot tree and shrub counts based on the quantity of provided parking spaces, and stormwater planting densities. The buffering and screening standards also carried minimum height and screening opacity requirements to be achieved within a defined time frame.  These requirements directly impacted layout, grading, utility placement, and budget considerations. Concurrently, the proposed building footprint, vehicle and pedestrian circulation, property lines, and existing easements constrained where plantings could realistically be located, requiring careful coordination to satisfy both spatial limitations and code mandates. City and county jurisdictions regulated the same landscape elements but imposed differing approved plant lists, size requirements, spacing standards, and quantity metrics. Where discrepancies existed, we reconciled the standards and applied the more stringent requirements to ensure full compliance across both authorities. The stormwater treatment facilities required nuanced plant selection to withstand challenging hydrological conditions and varying maintenance levels, ensuring long-term performance. While facility sizing and location are typically determined by the civil engineer, the planting design is critical to the system’s functional success. Successfully balancing these regulatory, spatial, and performance demands required careful coordination across disciplines to ensure compliance without compromising site efficiency or long-term durability.

The Approach

As a firm, we approach every project with a consistent, client-focused mindset. Our priority is delivering high-quality design solutions that meet our client’s goals while adhering to climate conditions and local landscape code requirements. While regulatory standards shape the framework of each project, functionality is driven by the needs of our client and project stakeholders.

We design with cost-efficiency in mind at every stage. By anticipating potential review comments and construction challenges early, we minimize unnecessary revisions and reduce delays during permitting and installation. Our landscapes are designed for long-term performance, incorporating durable materials, cohesive planting design, and thoughtful plant selection and placement that maintenance teams can clearly understand and manage.

The result is a resilient, professional landscape that enhances commercial property value and maintains strong curb appeal over time. We work efficiently to meet permit deadlines and collaborate closely with architects, engineers, developers, and other disciplines to ensure a coordinated, successful project outcome.

The Process

• 1. Pre-Design and Code Research: Our firm meticulously compiles all aspects of the jurisdiction’s development code that apply to the site.  This information is the number one guiding principle in our landscape plans, ensuring they are comprehensive and pass permit reviews with minimal redlines.
• 2. Collaborative Coordination: We coordinate closely with civil engineers, architects, developers, and ecologists to ensure that grading, stormwater design, building placement, and utilities are fully integrated with the landscape plan. Early collaboration minimizes conflicts during permitting and construction.
• 3. Permit Set – Comprehensive Landscape and Irrigation Plans:
  • We produce a comprehensive Landscape Plan that includes specifications, construction details, and clearly stated metrics on how code requirements have been satisfied for City Reviewers to easily follow and use. Our specifications and details balance enforceable performance standards with practical construction realities — ensuring clarity for contractors without creating unnecessary cost burdens.
  • Our irrigation plans are developed in coordination with the planting design, site soil conditions, and overall hydrology to ensure long-term plant health and system performance. We prioritize water distribution uniformity and strategic hydrozoning to meet plant demands while minimizing waste and preventing overspray onto adjacent hardscape areas. System sizing, zone configuration, and material selection are carefully evaluated to balance installation costs, operational efficiency, and run-time demands. We coordinate with civil engineers to confirm adequate water pressure, point-of-connection location, and meter requirements early in design to avoid conflicts during permitting and construction.
  • The result is a water-efficient, durable irrigation system that supports plant longevity while reducing long-term operational costs.
• 4. Permit Review and Revisions: We respond promptly to city comments and coordinate across departments to resolve redlines efficiently, helping projects move through approval with minimal delay. For this project, the city wanted two more trees to satisfy a setback variance that had not originally included specific tree count metric guidance. Other discipline revisions also required minor plant placement adjustments. Once those updates were made, the plans were re-submitted to the City Review Board and passed.
• 5. During construction, we provide:
  • Construction observation
  • Plant procurement coordination
  • On local projects in the Portland Metro Area, we offer personal plant placement guidance
  • Post-construction check sheets (as required by the city or owner): ensure the installed landscape reflects the design intent and meets jurisdictional standards.
• 6. Maintenance Plan: Post-construction, we offer a design-informed maintenance plan tailored to the specific performance goals and constraints of the site. Because we understand the original design intent and code requirements, we provide maintenance crews with a clear, calendar-based checklist addressing pruning, fertilization, plant performance monitoring, irrigation oversight, sight lines, safety, and best mulching practices. Where plant decline or performance issues arise, we evaluate underlying conditions and provide strategic replacement recommendations to preserve the integrity and performance of the overall landscape system. This proactive approach protects the client’s landscape investment and ensures long-term performance.

The Result

The result is a landscape that balances code compliance, long-term maintenance realities, and budget considerations — without sacrificing professional curb appeal. By anticipating jurisdictional requirements, coordinating across disciplines, and designing with durability in mind, we help our clients navigate permitting efficiently and move into construction with confidence.

Our approach reduces delays, minimizes costly revisions, and delivers landscapes that perform as well as they look — enhancing both property value and long-term operational success.
