WUI Zone — Milpitas Hills
Three levels of protection — from essential annual cleaning to full rooftop sprinklers. Choose what fits your home's exposure and your insurer's requirements.
Milpitas sits between the Diablo Range foothills and the valley floor. Ed Levin County Park borders the city's eastern hills directly, and the Calaveras Road corridor connects Milpitas to significant WUI terrain above the city. Diablo wind events carry embers from these hillside areas into Milpitas neighborhoods each fall. ORS Clean removes the fuel and installs the barriers before fire season.
Fire season is here — most homes are ember-ready in one visit, booked within 48 hours.
Local Fire Risk
Milpitas occupies the northern edge of Santa Clara County at the base of the Diablo Range — a mountain range with extensive fire history and significant chaparral and grassland fuel loads. Ed Levin County Park borders the city's eastern hills directly, and Calaveras Road climbs from Milpitas into the Diablo Range terrain that carries Very High FHSZ designation from Cal Fire. The hills above Milpitas — in the Evans Road, Marsh Road, and upper residential district areas — sit at the direct WUI interface. The Calaveras Reservoir area and the broader Diablo Range terrain represent the same fire environment that generated the 2020 SCU Lightning Complex to the south. Seasonal Diablo wind events push dry air from the east directly into Milpitas neighborhoods, carrying embers from hillside fires toward the valley floor. The corridor between Milpitas and the Berryessa area of San Jose shares this eastern foothill exposure. California insurers have updated risk models for the northern Santa Clara County foothill communities, including Milpitas zip code 95035. Annual Level 1 pre-season maintenance with photo documentation is the minimum for any Milpitas home near the hillside edge.
Properties adjacent to Ed Levin County Park and in the upper Milpitas hills district sit at the WUI boundary with the Diablo Range. These homes face the most direct ember exposure during wind-driven fire events. Level 2 or Level 3 recommended.
The Calaveras Road corridor climbs directly into Very High FHSZ terrain. Properties along this road and adjacent hillside developments face significant open space fire exposure. Level 2 recommended for heavily vegetated properties.
Mid-city areas within the ember travel zone from the eastern Diablo Range hills. Level 1 annual cleaning with photo documentation is appropriate, especially given insurer scrutiny of the 95035 zip code.
Southern Milpitas shares fire exposure with neighboring Berryessa and East San Jose communities. Within ember cast range of the Diablo Range foothills during significant wind events. Level 1 annual minimum.
California insurers have updated risk models for Santa Clara County foothill communities, including Milpitas zip code 95035. Properties near Ed Levin County Park and the Calaveras Road corridor face the same regional insurer scrutiny applied to other Diablo Range foothill communities in the county. ORS Clean provides before-and-after photo documentation on every job you can forward directly to your insurance agent.
Every level includes full photo documentation. We email you a complete before-and-after report you can forward directly to your insurance agent. The report is laid out so you can forward it straight to your agent.
Most homes lost in California wildfires ignite from embers, not from the fire front itself — and in Milpitas the embers would come off the grass-and-oak hills to the east.
Ed Levin County Park, the Calaveras Reservoir terrain, and the broader Diablo Range foothills above Milpitas carry significant fire history and fuel load. A fire in this terrain generates immediate ember showers toward the neighborhoods below.
Seasonal Diablo wind events push dry, fast-moving air from the east directly into Milpitas. The terrain funneling above Ed Levin Park can accelerate wind speeds locally. Embers travel 1–2 miles ahead of a fire front — placing the Milpitas hills and valley neighborhoods within reach.
On the Milpitas hills the fuel is cured grass, oak leaves and seed heads blown off the open slopes — exactly what collects in gutters and roof valleys through the dry season. One ember landing in a gutter full of it can light the roofline.
Rooftop sprinklers switched on ahead of an approaching fire keep the roof surface wet so embers can't catch. For the hillside homes along Calaveras and below Ed Levin, sprinklers plus clean gutters and vent barriers is the strongest protection we install.
Choose your protection
Three clear levels — from the annual ember-season minimum to a complete active-defense system. Not sure which fits? Get a free assessment.
The essential annual clean every Milpitas home should complete before fire season — removes the two biggest ignition risks from your property in a single visit.
Best for All Milpitas homes — the annual minimum before dry season
Everything in Level 1, plus physical ember barrier installation on attic vents — sealing the most common entry point embers use to ignite a home from the inside.
Best for Homes near open space, heavily treed lots, hillside properties
The complete protection system for homes in or directly adjacent to WUI zones — combines all cleaning and mesh protection with an active water defense system.
Best for WUI-adjacent homes, Ed Levin Park boundary, Calaveras Road corridor, upper Milpitas hills

Common questions
Properties adjacent to Ed Levin County Park and in the upper Milpitas hills district face the highest direct exposure. The Calaveras Road corridor connects directly to Very High FHSZ terrain. Central Milpitas and the Berryessa border area are within ember cast range of the eastern foothills during Diablo wind events. The entire 95035 zip code is within the regional insurer scrutiny zone for Santa Clara County Diablo Range communities.
Level 1 (Ember Ready): gutter cleaning plus full removal of all dry debris from the roof surface. Level 2 (Ember Defended): everything in Level 1 plus ember barrier protection installed on attic vents — the most common entry point for embers to ignite a home from within. Level 3 (Maximum Defense): everything in Level 1 and 2 plus rooftop sprinkler installation, with optional under-eave misters for additional protection at the eave line. All levels include before-and-after photo documentation.
Yes, in many cases. California insurers in high fire risk zones increasingly require documented evidence of roof and exterior maintenance as a condition of coverage or renewal. ORS Clean provides a before-and-after photo report on every job that you can submit directly to your insurance agent. The report shows the gutters and roof surface before and after, with the date, so your agent can see the maintenance was done.
Twice per year is ideal for Milpitas hillside homes — once in spring (April–May) to clear winter oak debris before the hills dry out, and once in late fall (October–November) after leaf drop. The fall window is especially important for homes with heavy tree coverage. At minimum, a pre-summer clean before California's fire season begins significantly reduces risk. We can set you up on a recurring schedule.
The homes with the most direct exposure are on the eastern edge of town: along Calaveras Road as it climbs into the hills, the upper Evans Road area, and the hillside neighborhoods that back onto Ed Levin County Park and the open grassland below Monument Peak. Neighborhoods closer to I-680 sit lower and farther from the open space, but during strong east-wind events they can still be within reach of wind-blown embers. Homes on the valley floor west of I-680, near the Great Mall and along the Bay side, carry the least risk.
Parts of the eastern hills — toward Ed Levin and along Calaveras Road — are mapped in Cal Fire's fire hazard severity zones; most of the flat valley floor is not. You can look up your exact address on Cal Fire's official fire hazard severity zone map. If you're in or next to a mapped zone, Level 2 is a sensible starting point.
Usually not beyond the basics. On the valley floor the realistic risk is low, so a yearly gutter cleaning before summer covers it — that's our Level 1, or simply our regular Milpitas gutter cleaning. Ember barriers and sprinklers are for the hillside homes on the east side.
