Boulder, Colorado
Boulder's first residential subdivision and a designated local historic district. Tarrant Avenue is a divided street planted with silver maples; alterations visible from the street require Landmarks Board review.

Computed from this demo's 47-property dataset, not from MLS data. On a production site these figures would come from the same IDX feed as the listings and would move every night.
The place
1870s–1920s Victorian, Queen Anne and Craftsman houses. Exterior changes are subject to historic review; interiors are frequently modernised.
Two blocks north of Ashdon Street Mall; RTD Hop and Skip routes; Boulder Transit Center at 14th & Walnut.
North Boulder Park, Mount Sanitas trailhead at the west end of Tarrant Avenue.

It is unlawful — and it would be poor advice — to describe a neighborhood by the race, color, religion, sex, national origin, familial status or disability of the people who live in it, or to steer anyone toward or away from a place on those grounds.

A written comparative market analysis for any address in Mapleton Hill, using the actual comparable sales rather than an automated valuation. Two days, no cost, no obligation.

Colour
Twelve schemes. Picking one repaints every branded surface on the site — header rules, buttons, links, focus rings, gradients, icons, tags and the light-shaft field — and the choice follows you from page to page.
Each chip shows that scheme's real ramp — deep, base, mid, lift, then the secondary — computed with the same OKLCH derivation the page uses. Text weights are resolved against a measured contrast ratio on both the light and the dark ground, so no scheme here is offered and then corrected once you pick it.
Reading
High contrast drops the decorative washes and pushes body text to pure ink on pure ground, in whichever theme you are in.
Reduced stops the light-shaft field entirely, freezes the parallax window, ends the hero sequence on its current frame and turns every scroll-driven animation off.
