On 1 August 2005 the city council awarded contracts for the construction of the full project to a construction company as well as approving the support contracts required to complete the project. Construction is expected to begin in September 2005, and should be completed and on-line by Spring of 2009.

PRBO Conservation Science is building their new national headquarters in the Oakmead Northbay Business Park on a site at the southeast corner of Shollenberger Park. They should move in by the end of 2005. PWA and the City of Petaluma are looking forward to a long and fruitful partnership with this nationally acclaimed bird research organization.

THE DESIGN OF THE NEW PETALUMA WASTEWATER TREATMENT PLANT (7/04)
After several years of design modifications, the city has decided to build their new wastewater treatment plant on about 25 acres in the upper portion of the 270 acre Gray's Ranch, which the city purchased in early 2004 (see illustration below - August 18, 2003). The primary and secondary treatment modules will include two elliptical oxidation ditches, biofilters, and two clarifiers. The site will also include the laboratory, tertiary filtration filters, disinfection units, and other hardware associated with the operation. Connected to the plant will be 45 acres of polishing wetlands, divided into four ponds.

About 230 acres of the site will be open to the public with walking trails, educational areas, public parking, and access to the natural brackish tidal marsh that occupies the lower third of the property. There will be a connecting trail to Shollenberger Park. The old oxidation ponds, located on the adjacent property (to the south), will be renovated with ponds nine and ten being converted to densely vegetated treatment wetlands.

The project is going out for bids in the Autumn of 2004, with construction to begin in the Spring of 2005. The project is estimated to be finished in 2008. The public access to the freshwater polishing wetlands and the natural tidal wetlands will provide a wonderful venue for enjoying wildlife and participating in the many wetlands/watershed education programs being planned for the site. Money to create some of the "public amenities" on the site is lacking and will be sought along the way. Thus some features, such as an education center, may appear after the project finishes in 2008.
