Subdividing Encinitas lot

[Chelsa Analei Seawolf]

Anyone have any experience subdividing in San Diego? I recently acquired a 1.6 acre property in Encinitas on Manchester on the lagoon— with the intent to build a modest house near my favorite surf break, and recoup costs by parceling off the other half of the land . 

The property is R2 zoned, and subject to Coastal Commission regulations. I am able to subdivide, and have had the land surveyed.

I’m so out of my league though. Help! Lol
anyone have any experience they can share? Mistakes to avoid etc?
