Why 95391 tot lots load up faster than the equipment maker expects
Mountain House playgrounds sit in a wind corridor with open ground on three sides, so fine grit and organic dust bond into the plastic texture and settle into the rubber surfacing pores.
The village parks — the Wicklund and Questa lots, the greenbelt play areas — take sustained afternoon wind carrying field dust. That dust is what turns bright plastic chalky in a couple of seasons.
Poured rubber holds it worse than the structures do. The surface is intentionally porous for impact attenuation, and grit works down into it where a broom cannot reach it.
Shaded north faces add biological growth on top of the dust. Greenbelt-adjacent lots with irrigation nearby get a green film on the lower panels and along the border curb that reads as neglect long before anything is unsafe.

Pressure limits and what they protect
Play structures are washed at low pressure with soft-bristle detailing, and poured rubber surfacing is never hit with a rotary or a high-pressure tip.
Rotomolded plastic panels and slides scuff and haze under high pressure, and once the surface is hazed it holds dirt faster than it did before. Low pressure plus contact detailing is slower and it keeps the finish.
Poured-in-place rubber is the real risk. Pressure lifts the wear course from the cushion layer, and a lifted seam is both an expensive repair and a trip hazard on a certified surface.
Powder-coated steel posts and deck plates get the same low-pressure treatment. Chipping powder coat on a play structure means rust bleed within a year in Mountain House irrigation spray.

Sanitizing, rinsing, and re-opening the lot
Cleaning agents used on play surfaces are applied at label dilution and then flood-rinsed with fresh water, so the lot re-opens the same day with no residue on hand-contact surfaces.
The rinse is the part cheap jobs skip. A structure that has been washed but not flooded still carries film on grab bars and slide entries, which is exactly where small hands go.
Timing is straightforward: these lots are cleaned early, so the structure and rubber are dry and the barricades come down before the after-school crowd arrives.
For HOA and district clients we photograph the closed and re-opened lot with time stamps, which is the documentation a board or a risk manager actually wants in the file.

How playground scopes are quoted in Mountain House
The walk counts structures, surfacing area by type, shade sails, benches, tables and border curbing, and each element is a separate line on the bid.
Playgrounds are too variable for a published per-square-foot number, and the surfacing type changes the method entirely — poured rubber, engineered wood fiber and turf are three different jobs on the same footprint.
Shade sails are quoted separately because they need to come down or be washed in place depending on the fabric and the frame, and that is decided on the walk.
The $297 standalone minimum applies to small single-structure lots. Most Mountain House HOA tot lots are larger than that once surfacing and site furniture are included.
