Why storm damage happens in Hilmar
Hilmar's hardest recent winter ended in a federal disaster declaration for Merced County. FEMA approved major disaster 4683 on 14 January 2023 for severe winter storms, flooding, landslides and mudslides with an incident period from 27 December 2022, and Cal OES lists Merced County for both individual and public assistance. Turlock #2, the nearest normals station, gives December, January and February 2.26, 2.63 and 2.29 inches. A roof that wind opens in those months meets the next band of rain within hours.
Farm buildings on the edge of Hilmar fail at their eaves and ridges. The Community Plan puts numerous dairies west of town, most of them tied to Hilmar Cheese Company, with orchards growing fruit and nuts on the east side and field crops to the south. On a large-span metal roof, wind gets under the panels at the eave and ridge and peels them back, and an open-sided shed takes the gust from underneath. Loose sheets are fastened down or covered before the next gust carries them into a yard or onto a neighbouring roof.
Hilmar grew fastest from the 1970s to the 1990s, and on tract lots of that kind wind takes fences, gutters and fascia first. Of the 2,073 homes in the Census Bureau's 2020-2024 survey, 1,313 date from those three decades, and 238 are mobile homes. A landscape tree standing in soil softened by days of rain can uproot in strong wind and come down on a roof or a carport. The hole it leaves is covered before water reaches the ceiling below.
Rain that gets past a broken window or roof in Hilmar has few places to drain once it is outside again. Lander Avenue divides the storm system in two, and TID Lateral No. 7 receives what both halves collect. The Plan records low ground and groundwater close to the surface on the west side, and Irwin, at the south end of town, has no storm drain system of any kind. So the tarp or plywood goes on first, and any wet ceiling or floor passes to drying.
Along Lander and Bloss avenues, a single broken opening leaves a business exposed overnight. The Plan's traditional downtown is the Mixed Use stretch of Lander Avenue running from American Avenue up to 1st Street, and Bloss Avenue is the town's industrial collector, with Hilmar Lumber named as the model use. Plywood over a shattered window keeps weather and intruders out alike. The CDI claims guide names plywood and plastic sheeting as temporary repairs, and warns that ensuing damage may go uncovered without reasonable steps.
Merced County's hazard plan records that on 24 October 1998 the first significant rain of that season, 0.75 inch measured at Merced in roughly two hours, put water in streets just south of Hilmar. A roof damaged over the summer meets its first test in a burst like that.
Storm damage repair, as delivered in Hilmar
The drive from the Modesto base is 19 road miles: Highway 99 as far as Turlock, then Lander Avenue, State Route 165, the one arterial serving Hilmar. Every visit writes to a single make-safe log and photo record.
The run is Highway 99 south to Turlock and Lander Avenue into Hilmar, inside 90 to 120 minutes at any hour. Merced County's hazard plan puts tule fog from November through March, some years into May, and says it slows emergency vehicles, so a foggy night runs toward two hours. Propertyvendr confirms the time.
No one stands under a hanging limb or near a line touching a tree, roof or fence, since a limb under tension can shift when cut. On a farm lot the hazard zone takes in sheds and yards, and the utility is called before any cut near a line.
Openings, roof sections and damaged belongings go on photo and video, outside and in, before anything is shifted, and every call about the loss is written into a log.
Limbs and trees come off a Hilmar roof with the site under a qualified tree worker, as Title 8 section 3421 requires.
Roof openings get a tarp fastened against the next gust, with fall protection over 6 feet on a house roof (Title 8 section 1731) and over 20 feet on larger roofs (1730). Plywood goes over broken windows and doors on houses, mobile homes and shops.
Any wet ceiling, insulation or floor moves to water damage restoration in Hilmar that day.
Merced County Building and Safety, 2222 M Street, Merced, permits the permanent repair, which is scoped for the adjuster; receipts for every purchase stay in the file.
Where storm damage happens in Hilmar
Storm exposure in Hilmar follows the building: Lander Avenue mixed uses, low west-side lots, Bloss Avenue roofs and farm buildings.
Downtown Hilmar, Lander Avenue from American Avenue to 1st Street
The Plan's downtown, where the relocated Mission Covenant Church, now Hilmar Covenant Church, stands at Lander and American. A limb or sign driven through a window here opens a business onto a road carrying up to 14,600 vehicles a day.
Lander Avenue corridor south of Bloss Avenue and the old Irwin town site
Detached houses on bigger lots, some now used as offices, and old Irwin's centre below Geer Avenue, its buildings renovated before 2008. With no drainage system in Irwin, rain let in by a wind-opened roof stays on the floor until extracted.
West of Lander Avenue (Census Tract 4.04)
Houses on single-family zoning, a small pocket zoned R3 and fields further west. On low ground over a shallow water table, a tarp that lets go puts rain into a house whose lot cannot carry it away.
East of Lander Avenue and the TID Lateral No. 7 edge
Houses near the highway mixed with commercial and light industrial zoning, and a trail buffer along the lateral facing the orchards. On the houses at that edge, fences, gutters and fascia are the first parts to go in strong wind.
1st Street golf-course drainage basin
The idle private course on 1st Street doubles as the community's storm basin when rain peaks. A house nearby that loses part of its roof in such a storm takes water while the basin is already filling.
Bloss Avenue industrial strip and Hilmar Lumber
The collector that carries Hilmar traffic toward Highway 99 and Livingston, lined with industrial lots. Wide roofs lose panels or edge flashing in wind, and one lifted edge lets rain across a large floor.
Hilmar Cheese Company plant, north of the Plan area
Hilmar Cheese Company sits a quarter mile beyond the Plan boundary and employs more than 500 people. At a plant that size, make-safe starts by keeping staff clear of a damaged roof edge or a line on the building.
Schools, Community Center and Fire Station 95, Lander and Geer
Elim Elementary, Hilmar Middle, Hilmar High and the continuation school stand by Lander near Geer, with the Community Center off Falke Street. A classroom window broken in a storm is boarded that night so the building stays closed.
Villa Cordoba, the mobile home parks and sewer Trunk Line "C"
The 2008 Plan places mobile home parks in this part of town without locating them closely, and the census place counts 238 mobile homes. A limb resting on a manufactured home is lifted off before the opening is tarped.
Camden Drive, American Avenue and Bloss Avenue housing sites
Farmland parcels zoned R-1 in the County's inventory, 32.10 acres at Camden Drive and American Avenue among them. The existing houses beside them face open ground, where fences and gutters meet the wind first.
Golf Link Road, Lana Lane and Country Club CWD
North of town: 23 homes in Country Club County Water District and a 22-lot subdivision on Lana Lane and Golf Link Road, each home on its own well. A tree on a roof here comes off under the same Title 8 rules.
Dairy and orchard fringe
Orchards east, field crops south and numerous dairies west, most tied to Hilmar Cheese Company. Metal panels on barns and shops lift at the eave and ridge, and open-sided structures take wind from below.

Questions from Hilmar property owners and managers
Merced County's Building and Safety Division, 2222 M Street, 2nd Floor, Merced, which issues building permits and inspects all construction in the unincorporated county, Hilmar included. It accepts applications electronically and keeps office hours Monday to Friday, 8:30 am to 4:30 pm. A County permit stays valid for six months after issue, and each inspection extends it by six months, so a repair that waits on the adjuster's scope does not lose its permit while work continues.
The opening is tarped first, so no more rain comes in. Merced LAFCO records that Irwin, the southern part of Hilmar, has no drainage system, so water that got inside will not find its own way out. The crew photographs the wet rooms and passes ceilings, insulation and floors to water damage restoration, and the photos and log show the adjuster the roof opening and the water it let in.
Everyone is kept clear of the loose sheets, which can move again in the next gust, and the building is photographed inside and out before anything is touched. The lifted panels are then fastened or covered, and any opening in the walls is boarded. Hilmar is ringed by dairies, orchards and field crops, and the permanent roof repair is scoped separately as commercial roofing, with the permit from Merced County Building and Safety.
The California Department of Insurance's residential claims guide asks policyholders to make temporary repairs to prevent further damage, naming plastic sheeting and plywood, and it warns that a policy may not cover ensuing damage if reasonable steps were not taken. What the policy pays is between the owner and the insurer. The make-safe log records each step taken on the house or mobile home, and the guide also asks for a log of every call and letter.
FEMA's guidance is to take photos and video of the damage, inside and out, to the structure and to belongings, before anything is thrown away. For a rental that means each room the tenant uses, the roof or window opening and any limb still in place. Receipts for purchases and repairs go into the same file, and FEMA advises consulting the adjuster or insurer before signing any cleaning, remediation or maintenance agreement.
They are two separate services. Storm damage repair makes the building safe and closed: the hazard zone, the limb off the roof, tarps and plywood, and the record for the adjuster. Hauling the cut limbs, broken panels and other debris off a Hilmar lot afterwards is storm and fire debris removal, which has its own page and its own request.
