         C.   No such projection may be built which in the event of failure could constitute a hazard or fall onto either public right-of-way or property, or another private property
      2    Civic Buildings. Buildings housing civic use types may be built to a maximum height of 60 feet.

      3.   Special Use Permit Approvals. The City Council, following the recommendation of the Planning Commission, may grant an exception from the height limit for a zoning district for a Special Use as part of its approval of that use. The limit or extent of this exception shall be a specific part of the Special Use Permit.
      4.   Coverage and Landscaping Requirements. Individual lots in an innovative development are exempt from maximum building and impervious coverage limitations and street yard landscaping requirements established for the zoning district. However, the subdivision as a whole, including streets, walks, and access ways, must comply with the building and impervious coverage regulations for its zoning district.
