The Wash: What You Should Know A seasonal wash (dry arroyo) runs through the middle of this 5-acre parcel. It’s dry most of the year and only carries water briefly after heavy rain or spring snowmelt — but it shapes how you’d use the land, so here’s the honest picture. What the wash adds: Character and privacy. The wash gives the parcel natural contour and texture that flat, featureless lots in the area don’t have. It creates a natural dividing line and a sense of separation from neighboring parcels. Greener vegetation and wildlife. Moisture collects along the drainage, so plant life tends to be denser there — which in turn draws birds, rabbits, deer, and other wildlife. If you’re buying for camping, hunting, or wildlife watching, the wash is where the action is. A built-in landmark. On open San Luis Valley land, a wash makes your property easy to find and gives campsites a natural, sheltered feel. What to plan around: Don’t build or park in it. During summer monsoon storms, washes can carry fast-moving water with little warning. Any future cabin, shed, or RV pad should sit on the higher ground to either side — and there’s usable ground on both sides of this one. It divides the parcel. Because the wash crosses the middle, moving between the two sides may require crossing the drainage. Plan your access and building site with that in mind. Verify before you build. As with any Costilla County parcel, confirm setbacks, drainage requirements, and permit rules with Costilla County Planning & Zoning before construction. Bottom line: if you want a perfectly flat build site, this isn’t your lot. If you want 5 acres with natural character, better-than-average vegetation, and a price of $8,000 (or $169/mo owner financing), the wash is a feature you’ll enjoy — as long as you build smart and stay on high ground.
