Why Proper Drainage is Critical in Somerville
Somerville's older housing stock, combined with its urban density and historical combined sewer system, makes managing stormwater a priority for both homeowners and the city. Ineffective drainage can lead to foundation cracks, mold growth in basements, ruined landscaping, and contribute to localized flooding. The city actively promotes solutions that reduce the burden on public infrastructure, making proper residential stormwater management a community responsibility as well as a personal safeguard 1 2.
Common Residential Drainage and Grading Solutions
Homeowners in Somerville have a range of options, from traditional engineering to green infrastructure that benefits the environment.
Regrading and Land Shaping
This is the foundational step for most drainage projects. It involves reshaping the soil to create a slope that directs surface water away from your home's foundation. A standard guideline is a minimum slope of 1/2 inch per foot for at least 10 feet away from the foundation 3. Correcting the grade is often the first and most cost-effective step in solving surface water pooling issues.
French Drains and Subsurface Drainage
For water that collects underground or in low spots, a French drain is a common solution. This involves digging a trench, laying a perforated pipe wrapped in fabric, and filling it with gravel. The system collects subsurface water and safely redirects it to a storm drain, dry well, or other suitable discharge point 4 5.
Green Stormwater Infrastructure (GSI)
Somerville encourages GSI systems that use natural processes to manage runoff 1 6. These attractive, eco-friendly options include:
- Rain Gardens: Shallow, planted depressions that collect runoff from roofs or driveways, allowing it to soak slowly into the ground while filtering pollutants 7 8.
- Dry Wells: Underground structures that collect water from downspouts or drains and allow it to percolate deep into the soil 5.
- Permeable Pavement: Materials like porous pavers or gravel for walkways and patios that let water pass through, reducing runoff from hard surfaces 7 9.
Complementary Tactics
Simple measures can significantly improve water flow:
- Downspout Extensions: Ensuring gutters discharge water at least six feet from the foundation is a critical and low-cost fix 4.
- Swales: Shallow, grassy channels that guide water across a property.
- Catch Basins: Grates connected to underground piping that collect surface water from driveways or low points.
Understanding Somerville's Regulations and Permits
Before starting any significant project, it's crucial to check local requirements. The City of Somerville requires permits for land disturbance activities that could impact stormwater flow or the city's drainage system 10. A site construction permit from the City Engineer is typically needed for projects involving major grading, excavation, or installing new drainage infrastructure 11. Always contact the Somerville Engineering Division to determine if your planned work requires a permit.
The Professional Drainage Project Process
Engaging a professional ensures your system is designed and installed correctly for long-term effectiveness.
- Site Assessment and Diagnosis: A specialist will identify the source of water, evaluate soil composition, locate utility lines, and determine the high and low points of your yard to diagnose the problem accurately 12 13.
- System Design and Planning: Based on the assessment, a plan is created that may combine several solutions (e.g., regrading with a French drain leading to a rain garden). This plan should account for Somerville's slope requirements and optimal discharge locations 14.
- Permitting: Your contractor will often handle the application process for any required city permits, ensuring the project meets all local codes 10.
- Excavation and Installation: This phase involves the physical work: moving earth for grading, digging trenches for pipes, and installing all drainage components 15.
- Backfilling and Restoration: Once systems are in place, trenches are filled with gravel and soil, and the site is restored with topsoil, sod, or plantings to blend with your existing landscape 16.

Cost Considerations for Drainage Work in Somerville
Costs for yard drainage and grading in Somerville vary widely based on the property's size, slope, accessibility, and the complexity of the solution chosen. Below are general estimated ranges for residential projects 17:
- Minor Grading Corrections: Adjusting soil slope in a specific area may range from $500 to $2,000+, heavily dependent on the amount of fill dirt and labor required 18.
- French Drain Installation: As a common subsurface solution, costs are primarily driven by length and depth, often starting around $1,000 to $4,000+ for a typical residential application 19.
- Rain Garden Installation: This green solution cost is variable based on size and plants, but is often more affordable than extensive piping, potentially ranging from $500 to $3,000+ 20.
- Comprehensive System Installation: A full professional design and installation that may combine regrading, multiple drains, and discharge solutions typically ranges from $2,000 to $10,000+ for a complete yard drainage overhaul 21 22.
Most reputable landscape and drainage contractors offer free initial consultations and bids, providing a clear cost estimate after assessing your specific situation.
Maintaining Your Drainage System
Property owners are responsible for maintaining private drainage systems 23. Regular maintenance includes:
- Keeping catch basin grates clear of leaves and debris.
- Inspecting and cleaning gutter downspouts and extensions each fall and spring.
- Ensuring the exit points of French drains or outlet pipes are not blocked.
- Checking rain gardens for sediment buildup and maintaining healthy plants. Proper maintenance ensures your investment continues to protect your home for years to come.
