Just got this from Modern Building Systems. Note that, per email below, no additional anchorage is needed—the soil
prevents sliding and there is no net overturning that would require anchorage tied into the ground. Please feel free to
print this email and attach it to the calculations. If the city has any questions,they can call me directly.

Dennis,
Original calcs attached.You'll note that the soil prevents sliding and there is no net overturning. So no additional tie
downs are needed for this type of installation.
