Projects Studies WATER City of Coos Bay, Storm Drain Master Plan In order to provide the City with a reference that could be used to systematically upgrade its storm water system, a master plan was developed to identify deficiencies within the system and to identify potential deficiencies created by development. The City, with a population of approximately 16,000 within city limits, serves a 2,300-acre storm drain area, including approximately 30 miles of piping. A significant factor is that a large portion of the study area is below the higher high tide level in Coos Bay and is protected by dikes. This necessitated a tidegate and outfall inventory for parts of the system. Over 30 tidegates were identified, many needing repair or replacement due to poor performance. There were also many active outfalls identified that did not have tidegates and were not found on City records or maps. Record drawings, electronic data, and field investigations were used to model and analyze the existing storm drain system under current conditions and with 20-year buildout. WASTEWATER City of Lakeside, Wastewater Facilities Plan The City's wastewater treatment plant is located adjacent to Ten Mile Creek, and due to low flow in the summer months, an alternative had to be developed for land application of effluent, since the small amount of acreage at the treatment plant was not suitable for year-round use. The final recommendation was to irrigate Lakeside State Airport, an area of approximately 30 acres, as a non-discharging alternative required by a Mutual Agreement and Order between the City of Lakeside and the Oregon Department of Environmental Quality. Because the WWTP is in a flood plain, and could not be enlarged, an upgrade to the treatment plant had to be sited elsewhere (North Site). Piping from the North Site plant was laid to the Airport. This project involved significant cooperation among multiple city, state and federal agencies. TRANSPORTATION City of Coos Bay, Transportation System Development Charges The Transportation System Development Charges study was completed in 2006. This study was needed due to additional demands being placed upon existing infrastructure from new homes and commercial facilities in the Coos Bay Urban Growth Boundary, and lack of an organized approach to financing new infrastructure. It resulted in a base index which will be used to automatically adjust systems development charges for new transportation infrastructure. MASTER PLAN Oregon International Port of Coos Bay Charleston Marina Complex Vision and Master Plan was the product of an intense effort by The Dyer Partnership and Shoji Planning and Development, LLC to develop a master plan for the direction and focus of future growth of a fishing community on the Southwestern Oregon coast that is seeing steady and growing use by recreational fisherman and water-oriented tourists. At the same time, it is also a working, commercial fishing and crabbing port. The intent was to develop a five-year plan to address properties and facilities owned and managed by the Port within this community which includes a marina, recreational vehicle park and shipyard. It addresses those facilities and their functions and the activities that can be carried out for the community when the Port works in partnership with community-based organizations, educational institutions (Oregon Institute of Marine Biology is located here.) and governmental agencies. Addressed are such issues as pedestrian and vehicle movement and parking, environmental stewardship, amenities, and port properties and services. STORM DRAINAGE Josephine County, Oregon, Storm Drainage Study This storm drainage study for Josephine County was done for the Willow Creek Drainage Basin, west of the city of Grants Pass. Willow Creek has historically been susceptible to flooding, so as further development of this area continued, an evaluation was needed so that the City and County could develop a comprehensive plan to systematically upgrade the storm water drainage system within the drainage basin. Current capacity of existing drainage pipes was calculated, surface area runoff volume downstream was calculated, and areas needing repaired were determined as well as what the proposed repairs and their costs would be. ENVIRONMENTAL REPORT City of Gold Beach, Environmental Report for Wastewater Improvements As part of Gold Beach's plans to construct improvements to its wastewater system, environmental issues needed to be addressed before planning could begin. Part of the project requirements involved improvement of water quality for Riley Creek. The City had an opportunity as part of the land acquisition for construction of a wastewater treatment plant expansion to acquire two acres of land at the mouth of the creek. The riparian habitat of Riley Creek had been severely degraded by deposits of fill and the growth of invasive species, so an assessment and recommendations were developed to reconstruct the wetland. Treated, disinfected effluent from the wastewater plant would be used in summer to irrigate the wetlands to improve the survival rate of the new vegetation.
