Stormwater & Drainage Design in Mount Vernon, WA

Northwest Datum & Design provides stormwater and drainage design with civil engineering and land surveying support for residential, commercial, subdivision, platting, and public projects throughout Skagit, Whatcom, Island, Snohomish, and San Juan Counties.

NWDD assists property owners, developers, contractors, public agencies, architects, attorneys, and design professionals with storm drainage systems, drainage review, hydrology, hydraulic engineering, erosion and sedimentation control plans, grading plan support, site plans, and permitting support.

Because NWDD provides both surveying and civil engineering services, stormwater and drainage design can be coordinated from the initial topographic survey and base mapping through engineering design, agency review, permit submittal, construction staking, as-built information, and project completion.

If you are planning a short plat, long plat, commercial site improvement, residential development, roadway or driveway improvement, utility extension, building site, drainage correction, or permit application, call 360-424-4865 or contact NWDD to discuss your project.

Stormwater Design and Drainage Systems

Stormwater and drainage design are often central parts of development and civil engineering projects in Northwest Washington. NWDD can assist with storm drainage systems, conveyance design, grading coordination, erosion control, and related site planning needs.

The design process may include review of existing drainage conditions, property and site constraints, topographic survey information, contour mapping, road and utility information, soils or critical area information provided for the project, agency requirements, and the proposed development plan.

Hydrology, Hydraulic Engineering, and Drainage Review

NWDD can provide hydrologic and hydraulic engineering support for projects that require evaluation of runoff, drainage patterns, conveyance systems, storm drainage facilities, and related site conditions. The scope of review depends on the project, available records, site conditions, and agency requirements.

Hydrology and hydraulic engineering information can support site plans, stormwater reports, road and access improvements, utility extensions, permit applications, and plan revisions during agency review.

Site Planning, Grading, and Erosion Control

Stormwater and drainage design often works together with site planning, grading, and erosion and sedimentation control. NWDD can prepare or coordinate design information for grading plans, temporary erosion and sedimentation control plans, drainage conveyance, access improvements, and related construction plan information.

When a project requires additional specialized review, NWDD can coordinate with qualified consultants in related disciplines as needed.

Permitting and Agency Coordination

NWDD can assist with permitting support related to stormwater, drainage, grading, erosion control, and civil engineering design. Project needs vary, but support may include permit exhibits, agency submittal materials and applications, response to review comments, plan revisions, SEPA checklist coordination, hydraulic project application support, fill and grade permit support, and coordination with reviewing agencies.

Coordinated Surveying and Engineering Support

Many stormwater and drainage projects begin with survey information. NWDD can coordinate property surveys, topographic surveys, base mapping, construction surveying, and civil engineering design so project information is consistent from the initial field work through design, permitting, construction staking, and as-built information.
