Short Plats, Long Plats, and Subdivision Support

Plat and subdivision work often begins with a review of the property, existing records, survey monuments, access, easements, utilities, topography, drainage conditions, and agency requirements. NWDD can provide survey and civil engineering information needed to help evaluate the property and prepare materials for review.

Project needs vary by jurisdiction and property conditions. Depending on the project, the work may include boundary survey information, topographic survey data, preliminary site planning, civil design, stormwater design, road and access layout, utility coordination, and permit exhibits.

Lot Line Adjustments and Boundary Line Adjustments

Lot line adjustments and boundary line adjustments are often used when adjoining property owners need to revise the location of a shared property line without creating additional lots. NWDD can assist with property survey information, record research, mapping, exhibits, and coordination needed for the requested adjustment.

Lot line adjustment work may include review of deeds, plats, recorded surveys, easements, access, utilities, existing improvements, and field evidence. The required scope depends on the properties involved, the reviewing agency, and the requested adjustment.

Surveying, Civil Engineering, and Stormwater Coordination

Many platting and lot development projects require both surveying and civil engineering. NWDD can coordinate property surveys, topographic surveys, base mapping, stormwater and drainage design, road and utility design, erosion control plans, construction staking, and related support so project information remains consistent through each stage.

This coordinated approach can help property owners and project teams move from early feasibility review through design, permitting, agency review, and construction with clear survey and engineering information.

Planning, Permitting, and Agency Coordination

NWDD can assist with planning and permitting support related to platting, lot line adjustments, civil engineering design, and surveying work. Support may include permit exhibits, agency submittal materials, response to review comments, plan revisions, SEPA checklist coordination, fill and grade permit support, and coordination with reviewing jurisdictions.

NWDD can also coordinate with owners, attorneys, title companies, architects, engineers, contractors, public agencies, and other consultants involved in the project.
