I sent these questions Friday via email but am following up submitting them through the web page. Since the GPP is coming ahead of the Comp Plan, these questions pertain to the documents that support the proposed amendments to the GPP.  I'm trying to understand the supporting document.

Under Constraints:

What flood plain year?

What % steep slopes?

Under Placetypes:

What is density per acre for: suburban low, suburban medium, suburban high, Town Center, and Mixed Commercial.

What is the housing type difference between suburban medium and suburban high, and why is there no suburban high on the FLU map?

What does PMT mean?

Attached units are a secondary use in suburban. Is this suburban low or medium? 

There is a placeype called suburban mixed but it doesn't appear on the FLU map, unless suburban medium = mixed.  Please clarify. 

Please provide a zoomable map with an environmental features layer overlaid with a unconstrained developable land layer.

What is the Urban Footprint Base Canvass and if it is mapped may I see it?

And finally (for now) some population questions regarding unincorporated Knox County:The Comprehensive Plan references the 2045 Mobility Plan for population projections. Page c-3 of this Mobiity Plan compares 2018 population (465,289) to projected 2045 population (570,688) resulting in an increase of 105,063.

The Quick Facts Census estimated 2022 population is 494,574 which when compared to 570,688 results in an increase of 76,114.The county's share of projected growth is mentioned twice in the Comprehensive Plan: 73%  and 75%.  Taking the higher % this results in a projected 2045 county population increase of 57,086.  If then divided by average household size of 2.4 the demand for residential units is roughly 23,786.  Not the estimated 31,000.

I would be curious to know the number of residential units approved by not yet built.

And if we could have any data that is more accurate that would help.  What do you think of this analysis? 

What is the assumption behind so little attached housing shown on the FLU map?  And so much suburban?  How does this meet the public's priority for conservation and affordable housing?  How does this meet the desire for nodal development?  Nodal development doesn't have to be a Town Center.  It can be clusters of higher density located near arterial and connector roads.

Sewer is given an extremely high weighting.  Is this existing or does it include proposed?  By including proposed (if it is included) aren't we letting utility companies dictate the extent of growth.  That is, just because it can be serviced doesn't mean it should be.
