@Scott Wolf I am an Engineer, just have plans of relocating in the near future. 

With that said, the best, easiest option for you is to take it to a civil engineering company to subdivide the property such that it meets local zoning requirements and to figure out how to protect the wetlands. 

After several hours, a very nice, early 60's engineer responded.

I will also check with the code enforcement in my local area to see any engineers listing and check prices. 

I am a civil engineer looking to move from Westchester, NY to Fort Lauderlade, FL.

I found Google Earth Engine not to long ago.

Now that I've graduated with a good job lined up I'm finally ready to take the first steps in beginning a new journey in buy and hold real estate.I'm currently living in the Tualatin/Tigard area and working as a mechanical engineer for a large semiconductor firm.

However, this home is in Berkeley and I am concerned about destroying historical elements and potential added structural engineering costs that could make the house attractive to a buyer in future years, along with the opportunity cost of construction now versus getting rental income from the house in the next few months. 

Additionally, the lot is splittable into 2, 3, OR a "cottage court", which allow up to 8 buildings on the property (this is all confirmed with the city and I consulted with a friend of mine who is an engineer and has drawn up several of these cottage courts and says its feasible). 

I also work full time as an Engineer and all-in-all I do enjoy it.
