Frequently Asked Questions
Common questions about our Site Preparation & Grading excavation services, process, service areas, and licensing. Have more questions? Give us a call or send us a message.
How much does site preparation cost in Los Gatos or the Santa Cruz Mountains?
Costs vary significantly based on lot size, slope grade, soil type, and proximity to sensitive habitat. Hillside properties with rock or hardpan require more time and specialized equipment than flat parcels. CStille provides free, no-obligation on-site estimates after reviewing your project specifics.
Do I need a permit for grading in Santa Clara County?
Most grading projects in Santa Clara County above a certain cubic yardage require a grading permit. CStille works alongside your project engineer and county inspectors to ensure all work is permit-compliant from day one.
Can you grade on steep slopes and limited-access lots?
Yes — steep-slope and limited-access grading is our core specialty. Many general contractors decline these jobs. CStille’s fleet includes equipment sized specifically for hillside access and confined work areas.
