Just bought 8.5 acres (830'x440' borders according to the county) right outside of Tucson and according to the flood map most of my land is considered "riparian" due to a dry creek bed that runs from the southwest corner into the middle of the property on the north. According to the county the dry creek bed can potentially have 5,000-10,000 cfs flowing through it and there is a minor risk of sheet flooding (0.5 cfs) throughout the rest of the property. There are two rocky raised areas on the southeast corner and the northwest corner. There is a 18' tall saguaro we named "Edna" in the northwest corner, a couple of ocotillos, some acacia (I'm thinking it's sweet acacia but I'm not sure), palo verde, mesquite, a few different types of cactus (mainly cholla) and a s**t ton of creosote!
I plan to build on the northwest raised area which is where the previous owners had a double wide which burned down to the metal frame. I want to use the frame from the double wide as a patio/deck when all is said and done. I would like to do as much as I can to keep as much water on my property as possible without damming up or interfering with the dry creek bed.
