Frequently Asked Questions.

What is a residential stormwater system?

A residential stormwater system is designed to collect, control, and direct rainwater away from your home and property.

Stormwater systems may include:

• Catch basins
• French drains
• Dry wells
• Perimeter drains
• Storm piping
• Detention or retention systems
• Downspout drainage systems

A properly designed system helps protect your home from water damage and flooding.

Western Washington receives significant rainfall throughout the year.

Without proper stormwater management, excess water can lead to:

• Foundation damage
• Flooding
• Soil erosion
• Crawl space moisture
• Basement leaks
• Landscape damage

A properly functioning stormwater system helps protect your property year round.

Common signs include:

• Standing water in the yard
• Water pooling near the foundation
• Wet crawl spaces or basements
• Soggy lawn conditions
• Soil erosion
• Water flowing across driveways or walkways

If you notice any of these issues, Northwest Cascade Construction can evaluate your property and recommend a solution.

Several factors can contribute to drainage issues, including:

• Poor grading
• Clogged drainage systems
• Inadequate stormwater infrastructure
• Heavy rainfall
• Soil conditions
• Improperly directed downspouts

Our team identifies the root cause and develops a long term solution.

A French drain is a trench containing gravel and perforated pipe that collects and redirects groundwater away from problem areas.

French drains are commonly used to:

• Protect foundations
• Reduce standing water
• Improve yard drainage
• Prevent crawl space moisture

They are one of the most effective drainage solutions for many residential properties.

A catch basin is a collection point that captures surface water runoff and directs it into a drainage system.

Catch basins help prevent:

• Flooding
• Erosion
• Water accumulation on driveways and yards

They are commonly installed in low areas where water collects.

A dry well is an underground structure that allows stormwater to slowly infiltrate into the surrounding soil.

Dry wells are often used to manage:

• Roof runoff
• Downspout drainage
• Excess stormwater from developed properties

They can help reduce standing water and improve drainage performance.

Permit requirements vary depending on the scope of work and local jurisdiction.

Projects involving significant grading, drainage modifications, or new construction often require permits.

Northwest Cascade Construction helps homeowners navigate permitting requirements and coordinate approvals when necessary.

Yes.

Water that collects around your home can create hydrostatic pressure against foundation walls and increase the risk of:

• Cracks
• Settlement
• Water intrusion
• Structural damage

Proper drainage is one of the best ways to protect your home’s foundation.

Absolutely.

Many homeowners install drainage improvements after experiencing water issues.

We can design and install systems that improve drainage around existing homes and landscapes.

Several factors may be responsible, including:

• Poor grading
• Compacted soil
• Inadequate drainage systems
• High groundwater levels
• Blocked drainage pipes

Our team can identify the cause and recommend corrective measures.

Yes.

Excess water can oversaturate soils and reduce the effectiveness of septic drain fields.

Proper stormwater management helps protect both your drainage system and your septic system.

A perimeter drain is installed around the foundation of a home to collect groundwater and direct it away from the structure.

Perimeter drains help prevent:

• Basement flooding
• Crawl space moisture
• Foundation water intrusion

They are a critical component of many residential drainage systems.

Yes.

Many properties throughout Western Washington are built on hillsides and sloped terrain.

We provide solutions such as:

• Surface drainage systems
• French drains
• Retaining wall drainage
• Slope stabilization
• Stormwater collection systems

These improvements help safely manage runoff and prevent erosion.

The cost depends on several factors, including:

• Property size
• Drainage challenges
• Soil conditions
• Type of system installed
• Access for equipment

We provide free estimates and site evaluations to help homeowners understand available options.

Most residential drainage projects can be completed within a few days to a few weeks.

Project timelines depend on:

• Site conditions
• Permit requirements
• Weather
• Scope of work

We provide realistic schedules and communicate throughout the project.

In many cases, yes.

Proper drainage can help:

• Protect structures
• Improve usability of outdoor spaces
• Reduce maintenance costs
• Prevent future repairs
