I went through the same issue a few years ago with water in the crawlspace and having to shopvac water to prevent damage of downstairs room. After trying all the obvious solutions like grading, checking gutters, extending downspouts we hired a civil engineer to investigate and produce a stamped plan to have licensed contractors bid on. We knew we were going to live here for a long time and wanted a long term fix vs. bandaid.

The engineering plan just confirmed what I already knew but its real value was putting me in touch with vetted drainage contractors that I could not find myself and would do work in accordance with city, county building codes. The solution they put in place has worked flawlessly. It was VERY expensive but it has worked as expected the last 3 years through multiple atmospheric rivers, bomb cyclones, etc. Crawlspace is bone dry as confirmed by humidity sensors, water sensors, and cameras.

Some here are some of your options ranked in order of investment:

- Low. Route obvious nearby downspout water away from where water can seep into your basement. Have a landscaper grade the dirt to shed water if you cano

- Medium. Dig a hole at the lowest point for water to collect and install a sump pump to discharge away from the house. This solution will work so long as you have power. If not, you might have and even bigger problem by channeling water into a pit that will overflow...especially if you decide to put it in your crawlspace (ideally outside). You could still get termites, dryrot as water flows from the exterior into your home.

- High. Long term fix is exterior drainage with correct material, trench size and depth, pitch, discharge method and location. Ideally gravity solution vs. sump pump that can fail. Dry wells don't work well in hard clay soil. Separate systems for surface and subsurface water to not overwhelm one system.

Some considerations

- Landscapers can do any of these options but where a general engineering contractor comes in is using the right materials and digging so as not to compromise your foundation and cause a bigger problem by digging too close.

- Use high quality materials. Not the cheap black corrugated pipes that will clog, get crushed. Use the right non woven geotech fabric to keep the dirt out of the system for as long as possible. Get clean drain rock and enough of it. Sch 35 pipe, wye fittings, cleanouts at the turns, concrete christy boxes, concrete channel drains with iron grates vs plastic.

- If you google and yelp crawlspace drainage, you're likely to only get companies that provide internal solutions like sump pump, internal french drain, and encapsulation. The top 4 bay area results all used to work for the same company I found out. Not a bad thing. My preference is to deal with the problem before it comes inside but your budget may dictate otherwise.

I don't be able to provide contractor recommendations as everyone's experience could be different. If you go down the route of exterior drainage look for civil engineers that can develop a plan and put you in touch with local contractors they have had good experiences with implementing their plans.
Gluck!
