     Assumptions:

    In Lot 33 (first left on AH St when turning off of Airoso St), the RG on the right end of the T is 478.5. This is assumed to be 476.5.
    In Lot 39 (last left on AK St when turning right off of Andaza St and left off of AM St), the first RG grade is 471.9. To match the correct slope, this is assumed to be 473.9.
    In Lot 16 (first rigth on Esencia Dr when turning south from Airoso St), the first RG grade is 529.2. This is assumed to be 527.2 to match slope. The end (straight in) is 527.8, this is assumed to be 528.8. The middle RG on the right is 527.1 and this is assumed to be 529.0. Slopes and comparison to other alleys is used to change these grades.

    For retaining walls between RW and pads, assume 2% up from RW to bottom of wall and top of wall set to TW elevations shown. 

    No TC grades are given on AF / AG St, so top of undercut is elevated to 1.64ft above RG grades shown. 
    In Lot 24 (third left on A St when turning south from B St), the first RG grade is assumed to be 512.6 to match the 1% grade, instead of 469.7.
    in Lot 26 (first left on A St when turning north from B St), the TCs at the alley of the entrance are labeled 521.5. This creates a hump on the west side of A St. These were assumed to be typos and adjusted to 519.1 on the north side of the alley and 518.94 on the south side of the alley.
    The east end of Chiquita Canyon on the north side has slopes drawn inside the curb. Since the model is only being built to the northern RW, the slopes / contours were ignored.
