Silver Hawk is a 300 lot, single-family residential subdivision located on 338 acres off of Marvin Road, approximately 3.25 miles north of Interstate 5 at the Hawks Prairie interchange. Construction of the Silver Hawk Water System began in 2007 with the drilling of the well. The Group A water supply system plan includes hydraulic analysis, source, storage capacity analysis, water right analysis, and a comprehensive system design analysis.
The land use for the Silver Hawk water supply has two different zoning classifications. Thurston County changed the original zoning classification of Rural Residential (RR 1/1) to its current classification of Rural Residential Resource (RRR 1/5) during land use review of the project. According to a court ruling, the subdivision was vested under the original zoning at Rural Residential (RR 1/1). Future land use will be restricted to rural densities of one unit per five (5) acres. Once the Group A water supply system is constructed, the system will not expand beyond the 300 equivalent residential units (ERUs) in the proposed development and will not affect future planning considerations.
The large high-end homes proposed for the Silver Hawk residential development far exceeded the Department of Health’s forecasting for excessive irrigation requirements and exceeded the minimum requirements for fire flow requirements.

A series of master-planned and small project commercial and industrial developments on land owned by the Port of Centralia. Projects included:
Park 3 Master Plan and Floodplain Development. A commercial park located within the City of Centralia. Hatton Godat Pantier provided project management, master planning, and survey and design services to obtain a Fill Permit and Floodplain Development Permit to fill areas within Park 3 to elevate future development areas above the flood plain. The project includes the construction of a complete stormwater management system for future development of the 40-acre complex.
North County Industrial Park. A heavy industry park, including new roads, storm drainage, bioretention swales, railroad crossings, power supply, and street lighting. Hatton Godat Pantier provided project management, design services, and surveying.
Northpark Industrial Park. A 33-acre project, this site was the Port’s first full-scale industrial development project. Hatton Godat Pantier provided master planning, engineering, design services, and all project management for the development’s infrastructure.
Southpark Industrial Park. A 106-acre light industrial and commercial business park, including road construction, utilities, and service lines. Hatton Godat Pantier provided design, engineering, and project management services.
As publicly funded projects, the Port of Centralia’s development plans involved special contracting procedures and specific formats for proposals and paperwork. These special state and federal regulations require expertise on the part of engineers, designers, and project managers, an area in which Hatton Godat Pantier brings a wealth of experience and skill.
“Even with a publicly funded development, at the end of the day, the goals are the same,” says Steve Hatton. “The project needs to be developed with all the nuance and detail of any private development, and that’s where we feel we can contribute something special, even to the public sector.”

Cooper Crest was the City of Olympia’s first “low-impact” development. A 140-lot subdivision, the project required a range of professional services from Hatton Godat Pantier, including:
Although Low Impact Development (LID) techniques have a solid academic basis for helping protect watersheds and fish and wildlife habitats, implementing LID in the real world is less well known. There is added complexity and cost associated with deployment, challenges that end users must deal with. These challenges called for an experienced and highly efficient engineering firm to minimize, wherever possible, the additional expenses associated with low-impact development and create techniques that actually work in the “real world.”
“Low-impact developments, though cutting-edge, aren’t suited for every project,” said Jeff Pantier. “These projects are more labor-intensive and require specific and generally higher-margin inputs. That is why using a design and engineering firm with expertise in these kinds of developments is important.”

Simpson Timber Company operates sawmills in Washington and California, producing dimension lumber. This project at the company’s 400-acre Shelton facility involved two key on-site improvements at the Simpson Mill #5 and log-sorting yard. The first was the mitigation of localized flooding affecting the areas around the mill during heavy rains. The second was ensuring that the facility as a whole met Department of Ecology stormwater discharge standards.
To meet those goals, Hatton Godat Pantier provided full stormwater retrofit design services, including engineering of detention, treatment, and conveyance systems.
Although the Simpson Timber sawmill’s production technology was “cutting-edge,” the ground adjacent to the log yard often turned into a mud pit during heavy rains. The runoff drained into a storm pond, which emptied into a local creek. Though serviceable, the system was at risk of running afoul of state environmental regulations and needed to be significantly upgraded.
“We engineered a system using large settling ponds and a ‘decanting’ process to settle out suspended particulates – i.e., mud,” said Steve Hatton. “After the redesigned system was engineered and constructed, the client was able to meet strict state and federal NPDES guidelines for stormwater discharge.”

For more than 50 years, Cascade Pole and Lumber Co. (now a subsidiary of McFarland Cascade Holdings, a national decking manufacturer) had produced creosote-treated fir poles for telephone and electrical lines and other commercial uses. Cascade Pole operated its plant on a site owned by the Port of Olympia and adjacent to the popular Swantown Marina on Budd Inlet (part of Puget Sound). After Cascade Pole vacated the property, the Port was charged by the Department of Ecology with clean up and recovering the site.
Cleanup actions include:
There were multiple moving parts and conflicting goals in this project: The cargo and freight-handling areas needed space. Marina operations needed boat and trailer parking. Plus, the future development vision for the North Pointe development included creating a shoreline trail, adding public space, and providing for future office and retail buildings. Hatton needed to balance and accommodate these multiple uses and needs.
“This project demanded a wide variety of project experience,” said Steve Hatton. “We were called on to deliver comprehensive engineering and design services, including surveying, engineering for roads, commercial development, parking lots and landscape design. It took a lot of creativity to manage and recognize all the various needs in this project, and I’m proud of how well we integrated the multiple uses identified for this project.”

The Village at Union Mills is a 130-unit apartment complex in Lacey, WA. The project consisted of a new one, two and three-bedroom flats and townhomes nestled in a rural setting, surrounded by protective wetlands. The upscale development featured garages, storage facilities, carports, and an outdoor pool and hot tub. It was a high-end development that required Hatton Godat Pantier’s expertise in the following areas:
This project’s developers spent more than a year attempting to complete necessary planning and pre-project engineering work using an out-of-town firm that lacked local knowledge and familiarity with regulatory and permitting processes. When Hatton Godat Pantier was engaged, the project was ostensibly close to breaking ground. But once onboard, Hatton Godat Pantier’s professional staff recommended that additional design and engineering inputs were needed beyond merely completing the permitting process.
“Initially, we had to take several steps backward on this project,” said Jeff Pantier. “There were several challenges with the project’s design as it stood, and we were called upon to provide engineering services, supplemental topographic surveys, and an ALTA (American Land and Title Association) survey for the lender. But with our help, the project got back on track and was completed to everyone’s satisfaction.”
