Details About our Survey Practice

Accurate surveys and maps smooth the way for the design process. Reid Middleton surveyors deliver precise and timely results. We perform surveying services for roads, highways, utilities, airports, waterfront facilities, and private and commercial developments.

With more than 70 years working on survey projects across Washington state, Reid Middleton has established itself as one of the Pacific Northwest’s premier survey firms, recognized for leadership and technical expertise. We believe a successful project begins with an accurate understanding of the existing conditions. Reid Middleton surveyors work with project stakeholders and the design team to understand project requirements and appropriate services. Our surveyors can help at any stage of your project, whether your project is in the early stages of planning or under construction.

When easements are granted to different entities over several decades, and on top of or cross each other, it’s frustrating and confusing for any client. Reid Middleton surveyors helped Rick, our client PM, get all of the easements relinquished; we were a constant source for him to help clarify and explain what easement belonged to whom and where.

Thank you for taking care of this, your efforts are greatly appreciated! It’s been great working with you and the Reid Middleton team.

Rick Ashleman, PM with Shoreline Fire Dept.
