Within the urban growth boundary of a city with a population greater than 25,000, local governments shall allow, subject to reasonable local regulations relating to siting and design, the development of at least one dwelling unit on each platted lot that is zoned to allow for single-unit dwellings, unless the local government determines that:

1. (1) The lot cannot be adequately served by water, sewer, storm water drainage or streets, or will not be adequately served at the time that development on the lot is complete;
2. (2) The lot contains a slope of 25 percent or greater;
3. (3) The lot is within a 100-year floodplain; or

4. (4) Development of the lot is constrained by land use regulations based on statewide land use planning goals relating to:

   1. (a) Natural disasters and hazards; or
   2. (b) Natural resources, including air, water, land, natural areas or open spaces, but not including historic resources.
