Lake Valley Estates
By Jessica Carcoana · Updated September 2026
Lake Valley Estates is not inside Longmont. Its 167 lots sit in unincorporated Boulder County off Niwot Road, about six miles southwest of the city limits, though the mail arrives addressed to Longmont 80503. Homes recorded between 1987 and 1997 stand on parcels running about 0.33 to 0.43 acres along golf named streets including Fairways Drive, Niblick Drive and Birdie Court, wrapped around the Lake Valley Golf Club. A shared recreation tract off Lake Valley Drive holds tennis and pickleball courts, a volleyball court and a playground, and Fentress Lake lies within the subdivision. US-36, the Foothills Highway, runs less than a mile west and the Diagonal Highway about two miles east.
