A 1,000-space RV park is included in the plans for a huge theme park that might be built along Interstate-5 about halfway between Portland, Ore., and Seattle, Wash.

A theme park developer from Valencia, Spain is interested enough in the project to invest $200,000 in a feasibility study, which should be completed before the end of this year, according to The Oregonian newspaper of Portland.

The Spanish company, Civis Project Management, is working with the Southwest Washington Public Development Authority, which hopes to diversify the timber industry-dependent economy of Lewis County, Wash.

The project under consideration would be comparable to EuroDisney in France, said Dwight Butt, executive director of the public development authority.

The authority hopes a private company would build a 1,000-space RV park, an exhibition center and a theme park on 350 acres near the village of Winlock, Wash.

Butt said he is “99.9% sure” the theme park and amenities will be built. It may take a year to get engineering and environmental studies completed, so construction, most likely, will not begin until 2002. The theme park probably would not be ready to open until 2004 or 2005.

Civis currently is working on completing the Oceanographic Park of Valencia, one of the five largest aquariums in the world.
