Historically we were allowed zero setback with our only issue being access. For example, the shop/storage up above, the WWTP, etc.

Nate & Kristi –

Similar to the question I asked for the BCF, I would like to know some information regarding the setback requirements for the WWTP.

QUESTION - We are unable to tell what the setback requirements are for the WWTP, as we are unsure of the land use designation, and it appears that both the SBRs and the dewatering building are minimal distances from the property lines with the adjacent street right-of-ways. Please confirm setbacks, and also if variances were gained for construction of either of these facilities that we might also be able to secure for locating the digesters (this would likely aid in construction sequence by allowing the post equalization basin to remain in use during construction of the digesters).

Terry – this may be an institutional knowledge question that you may have insight to.

Thank you –

^{^[1]} “0” in this column means that there is no density maximum. One can build as many residential units as can fit, as long as the rest of the requirements of this code are met (e.g., parking, open space, screening, maximum lot coverage, setbacks, etc.)

^{^[2]} “0” in this column means that there is no minimum parcel size. One can subdivide into as small of lots as one wants, as long as a permissible use can fit on the lot while meeting the rest of the requirements of this code (e.g., parking, open space, screening, maximum lot coverage, setbacks, etc.)

⁴ Maximum setbacks are required pursuant to §20.46.050 (Site Design in the Old Town Business Districts (1, 2, and 3)).

⁵ Airspace restrictions may limit the maximum building height to less than 50 feet.
