Why Proper Drainage is Critical in Bellevue

Bellevue's picturesque landscape comes with specific hydrological challenges. The city experiences significant rainfall, and many neighborhoods are situated on or near a high seasonal water table ¹. This means the ground can become saturated quickly, leading to surface pooling and subsurface water pressure against foundations. The City of Bellevue Utilities Department manages a comprehensive stormwater system, but the responsibility for managing water on your private property falls to the homeowner ². Implementing proper site grading and installing effective drainage systems prevents costly damage, controls erosion, and is often a requirement for any significant landscaping project ³.

Core Solutions for Residential Water Management

Addressing water issues starts with understanding the tools available. Each system serves a specific purpose, and a combination is often used for a complete solution.

Regrading and Slope Correction

Grading is the process of reshaping the soil to create a gentle, consistent slope that directs surface water away from your home's foundation and toward a safe discharge area, like a street gutter or a dry well ⁴. It's often the first and most fundamental step in solving drainage problems. Proper grading ensures water flows across the surface as intended, preventing it from settling in low spots or seeping into your basement.

Subsurface Drainage Systems

When water is coming up from below or saturating the soil, surface grading alone isn't enough. This is where subsurface solutions come in.

• French Drains: A perforated pipe is laid in a gravel-filled trench, typically at a depth where it can intercept groundwater. The pipe collects the water and channels it away to a discharge point. French drains are ideal for chronically soggy yards or for intercepting water flowing down a slope ^{5 6}.
• Dry Wells: These are underground chambers filled with gravel or a special vault that collect water from downspouts or drainage pipes. The water slowly infiltrates into the surrounding soil, recharging groundwater rather than overloading the municipal storm system. They are a key component of Bellevue's encouraged Low Impact Development (LID) approach ^{3 1}.

Surface Water Collection

For managing heavy runoff from driveways, patios, or other impervious surfaces, surface-level solutions are key.

• Catch Basins: These are grated inlets installed in low spots to collect surface water. They connect to an underground pipe network that carries the water away ⁶.
• Channel Drains (Trench Drains): Long, narrow drains set flush with the surface, often across a driveway or patio, that capture sheet flow and direct it into a pipe system ⁴.
• Dry Creek Beds: An aesthetic alternative to concrete channels, these use rock and gravel to create a natural-looking swale that guides and slows surface runoff while adding landscape interest.

Downspout and Roof Runoff Management

Your roof collects a massive amount of water. Simply letting it dump next to your foundation is a common cause of basement moisture and yard saturation. Solutions include underground downspout extensions that pipe roof water to a dry well, a drainage ditch, or a rain garden, safely moving it 10 or more feet away from the house ⁴.

The Professional Process: From Assessment to Inspection

Tackling a drainage project in Bellevue is a multi-stage process that often requires professional design and permitting.

1. Site Assessment and Problem Identification: A specialist will walk your property to identify all water sources (roof runoff, slopes, neighbors' yards), chronic problem areas (standing water, erosion, damp foundations), and soil conditions. Understanding the seasonal high water table in your area is a crucial part of this step ^{4 1}.

2. Design and Planning: This phase involves analyzing the existing conditions and creating a detailed plan. For many projects in Bellevue, this requires a formal Stormwater Site Plan ³. The plan must show existing and proposed contours, the location of all drainage structures (pipes, basins, dry wells), flow directions, and how the system ties into any existing city infrastructure. The design should also explore opportunities for LID techniques like rain gardens or pervious pavers ^{7 1}.

3. Permitting: The City of Bellevue requires permits for drainage work that alters the flow of stormwater on your lot or connects to the city system. Submitting the detailed site and civil plans is part of the permit application process ^{3 8}. Your drainage contractor should be familiar with these requirements and can often manage the permit application on your behalf.

4. Installation: This is the construction phase, involving excavation, precise grading, laying of pipe networks, installation of catch basins or dry wells, and careful backfilling. Proper installation is critical for system longevity and performance.

5. Inspection and Final Grading: The city will typically require inspections of the drainage system before it is covered. Once approved, final grading and landscaping can be completed to restore your yard ⁷.

Understanding Investment and Cost Factors

The cost of drainage and grading work in Bellevue varies dramatically based on the complexity of the problem, the solutions required, the size of your property, and the need for engineered plans. Here is a general overview of cost ranges based on common system components ^{9 10}:

• French Drains: Typically cost between $10 to $50+ per linear foot, with total project costs often ranging from $2,000 to $7,000 depending on length, depth, and complexity.
• Catch Basins: The basin unit itself ranges from $200 to $500+ (for plastic models), plus the cost of installation and connecting piping.
• Channel/Trench Drains: Can range from $30 to $100+ per linear foot installed.
• Dry Wells: A significant installation, often costing $1,600 to $4,800 or more per unit.
• Comprehensive Solutions: For properties with multiple issues requiring regrading, French drains, catch basins, and dry wells, total project costs can easily exceed $10,000 to $13,000+.

Navigating Bellevue's Regulations and Standards

Working within city guidelines is non-negotiable. Bellevue's Stormwater Engineering Standards provide the technical specifications for all drainage work ⁸. Key points for homeowners include:

• Low Impact Development (LID): The city strongly encourages techniques that mimic natural hydrology to manage rainfall where it lands. Incorporating elements like rain gardens or dry wells can sometimes simplify permitting and is better for the local environment ^{3 1}.
• Discharge Rules: You generally cannot discharge drainage system water onto a neighboring property. It must be contained on your lot (via infiltration) or directed to an approved city stormwater facility ⁴.
• Utility Location: Any excavation requires a call to 811 to have all public underground utilities marked. Your drainage plan must also show the location of private utilities ⁷.
