Keeping Seed Down in a Windy, Growing City
Hydroseeding in San Marcos keeps pace with a city that has grown fast. San Marcos had 3,896 residents in 1970 and 94,833 by 2020, with 13.2 percent growth in the last decade alone. Much of that growth landed on hillsides, which means graded pads, new slopes and yards that start out as bare soil.
Santa Ana winds
Hot, dry Santa Ana winds can strike San Marcos in any month, most often in August, and they raise the risk of severe wildfires. For seeding, those winds matter because they dry the seed bed in hours and can lift loose soil from freshly graded lots. We use a tackifier in every mix to bind mulch and seed to the surface, and we keep a closer watering schedule when wind is in the forecast.
More rain on the hills
The city averages about 13 inches of rain a year, mostly from November through March, but the San Marcos Hills receive up to 20 inches. Hillside homes get more water on their slopes during storms, so erosion control on those lots deserves extra attention. We use erosion control blankets on the steepest cuts and a bonded fiber matrix on moderate slopes.
Dust control on building sites
On large graded sites waiting for construction, a quick hydromulch application keeps dust down and stops rills from forming before the next phase. For lots near open space, a native or wildflower seed mix can give longer-term cover that suits the dry summers.
Farm and dairy roots
Farming was the main business here in the 19th and early 20th centuries, and dairies and poultry became major industries in the mid-1900s. Colorado River water arrived in the 1950s and set off growth beginning in 1956. Some older parcels still show the flat, worked ground of those operations, which usually grades out well for lawns.

San Marcos Questions
Will Santa Ana winds blow my new hydroseed away?
Tackifier in the mix binds the mulch to the soil so it stays put. The bigger risk is drying out, so we increase watering when winds are forecast.
We are on a hillside in the San Marcos Hills. Do we need more erosion control?
Likely. Those hills get up to 20 inches of rain, more than the valley floor, so steep cuts benefit from blankets or a bonded fiber matrix.
Can you hydromulch a graded lot that is sitting before construction?
Yes. Temporary hydromulch controls dust and erosion until building starts, and it can be done with or without seed.
Is wildflower seeding a good fit here?
On slopes and open edges, yes. A wildflower or native mix handles the dry summers better than turf in areas that will not be irrigated much.
