This is my plan for North Carolina. I have tried to make it compact and with minimum population deviation (The largest population deviation in my plan is a mere 907 people, a difference of -0.12%), but also make the map as balanced as possible.

The partisan makeup of my map is 6D-7R. This map is more compact than the current map, with 10 county splits, down from the current 13.



The PVI data is as follows:
1: R+8.69
2: R+18.59
3: D+13.96
4: D+7.21
5: D+3.27 (Near minority-majority, 50.6% white)
6: D+1.42 (Minority-Majority)
7: R+12
8: R+10.87
9: D+0.93
10: R+2.19
11: R+19.91
12: R+12
13: D+13.56  (Minority-Majority)

Yes, as they're still on NC, but it's a good idea to stay ahead, and have maps ready, that way it gives you more time to experiment with the states.

A little over two years ago Torie started a thread to look at the plans for states that had particularly partisan gerrymanders. One of them was NC and Torie and I went back and forth hammering out a plan that fit under the rules.

North Carolina has the following UCCs (cover, pack is 1 less):
Charlotte UCC (3): Mecklenburg, Gaston, Union, Cabarrus, Iredell, Rowan.
Raleigh UCC (2): Wake, Johnston
Winston-Salem UCC (1): Forsyth, Davidson
Durham (1): Durham, Orange
Asheville (1): Buncombe, Henderson, Haywood
Fayetteville (1): Cumberland, Hoke
Hickory (1): Catawba, Burke, Caldwell

This is the plan that emerged and will by my submission (Torie is welcome to join in as it was a joint project). All UCC covers are maintained and only one pack is missing for the Charlotte UCC. Only four counties were chopped, two of which had to be chopped because of size, and none were chopped more than once. Though VRA compliance is not required in this exercise, CD 1 groups together the rural counties with significant black populations (over 40%) as a community of interest. The whole county CD 1 is 40.3% BVAP and D+3 so the preferred candidate of the black minority would be likely to win both the primary and general election.



CD 1: +1797; D+3.06; BVAP 40.3%
CD 2: -3440; R+2.55; BVAP 27.5%
CD 3: +1084; R+8.07; BVAP 25.0%
CD 4: +2027; D+14.25; BVAP 20.0%
CD 5: +469; R+8.78
CD 6: -319; D+2.17; BVAP 26.7%
CD 7: -1146; R+8.71
CD 8: +22; D+0.96; BVAP 24.1%
CD 9: -326; R+19.08
CD 10: +1037; R+19.14
CD 11: -971; R+8.93
CD 12: -2472; D+5.03; BVAP 25.6%
CD 13: +2234; D+4.80; BVAP 22.9%

I know Forsyth and Guilford are both split, but keeping one whole would require an awkward split of one of the Triad cities. I figured an urban district that keeps all three cities intact and together while having the more rural parts with the 11th would make the most sense. The 3rd was kind of leftovers but I-40 runs perfectly throughout it so that actually turns out ok
1: R+10.92
2: D+4.66
3: R+11.05
4: D+2.92
5: D+6.99
6: D+14.93
7: R+16.02
8: D+9.07
9: R+10.85
10: D+13.05
11: R+19.9
12: R+18.39
13: R+8.93
Delegation is usually 7R-6D. Dems could flip CD-13 in a wave; Reps could pick up CD-4 and possibly CD-2 in a good year

Here are some additional features about NC in SPICE scoring.

The state has a PVI of R+3.00. Statistically that means with 13 seats the Pubs would be expected to have a two seat edge in the delegation. Since there are an odd number of seats a plan with 7 R, 5 D and one tossup would have a 0 SKEW.

Two counties have to be chopped due to their population: Mecklenburg and Wake. NC doesn't have defined county subdivisions like towns, but we have used planning regions to show the locally-recognized communities of interest. I'll find the files and post them.

Erosity is based on county connections. The following map shows which counties are connected, and how. Blue (highways both shades) and green (all-year ferry) links represent full connections between two counties. Yellow and gold links represent counties that are only connected by a local road, not a state highway. Orange and pink links show counties that are contiguous but not directly connected, that is one has to go through a third county to go from one county seat to another.

To guide chops, here's a map showing subunits and connections Mecklenburg county. Subunits are based on the 6 independent towns and 6 planning areas for Charlotte. Blue links are regional connections between counties. Gold links are local connections. Pink links are contiguous only without a connection.

This is my plan for North Carolina. I have tried to draw compact districts and cut down on splitting counties while keeping communities of interest and ensuring minority representation. The partisan split reflects recent election results as there are seven Republican districts and six Democratic ones. Located in the Sandhills region, the 9th district is the most competitive one and its PVI is D+2.



Basic facts about the districts are below.

CD 1: D+10; VRA district; 48% white & 44% black
CD 2: D+4
CD 3: R+9
CD 4: D+13
CD 5: R+18
CD 6: D+8
CD 7: R+10
CD 8: R+20
CD 9: D+2; majority-minority (49.8% white)
CD 10: R+12
CD 11: R+9
CD 12: D+16; VRA district; 49% white
CD 13: R+19

North Carolina has 16 planning regions. It used to have 18. There were separate regions for Winston-Salem and Greensboro. It also had a Pee-Dee Region, that apparently dissolved and the four counties scattered among four neighbors.



Collectively, the three big regions of Centralina (Charlotte), Piedmont Triad (Greensboro, Winston-Salem), and Triangle J (Raleigh, Durham) have a population equivalent to 7.212 districts. The five regions to the west have a population equivalent to 1.909 districts, and the eight regions to the east have a population equivalent to 3.879 districts. This suggests roughly a 2:7:4 division. None of the three central regions are close to an integer number of districts, and have sprawled outwards so it should be possible to combine fringe areas one way or the other.



The two westernmost regions have a population equivalent to 0.809 districts, and the western five equivalent to 1.909 districts. Moving Surry gets the western area to 2.009. Counties are then moved to the western area to reach approximately one district.

NC-1 (Appalachian, Asheville) 1.009
NC-2 (Western, Unifour) 1.000.

The two southeastern regions of Lumber River and Cape Fear have a population equivalent to 0.981 districts. The three northeastern regions of Upper Coastal Plain, Mid-East and Albermarle have a population equivalent to 1.047 representatives. Adjusting counties to get closer to 1.000, by dropping Beaufort and Hyde, and adding Greene, gets the Eastern Carolina region closer to a district which is done by adding Sampson.

Later I was having trouble assembling counties into meaningful districts. So I shifted New Hanover and Pender into the Eastern Carolina district, and added Cumberland to the southeast district. This has the added benefit of unifying the Fayetville UCC.

NC-11 (Southeast, Fayetteville) 1.005
NC-12 (East Coast, Wilmington, New Bern) 1.007
NC-13 (Albermarle, Rocky Mount) 1.004

This tends to increase the central regions to 8 districts as the greater Raleigh-Durham area will dominate three districts.

Dividing up the central area. An area based on Mecklenburg with a population equivalent to 2 districts was identified. Mecklenburg has to be chopped. My inclination would be to keep one district wholly in Mecklenburg, and bridge across between Gaston and Unon.

NC-3, NC-4 (Charlotte) 1.998

An area including northern suburbs of Charlotte and areas south of Winston-Salem was constructed.

NC-5 (Not your Father's I-85 District) 0.979

Two districts are created in the Greensboro/Winston-Salem and areas to the south. This will require a major split of Guilford and Greensboro.

NC-6 (Greensboro/Winston-Salem) 1.369
NC-7 (Greensboro, points south) 0.617

Collectively, 1.986.

The area around Raleigh-Durham collectively have a population of 3.010.

NC-8 (Durham, Chapel Hill) 1.062
NC-9 (Raleigh) 1.228
NC-10 (Raleigh suburbs, points east) 0.720.

Wake will be chopped. My inclination is to move Franklin in NC-10, and add a nibble of Wake to NC-8. NC-9 would be wholly in Wake and dominated by Raleigh. NC-10 would include the remnant of Wake, mostly in the south, but with an area in the northeast to link to Franklin.

So Mecklenburg, Wake, and Guilford, the three most populous counties would be chopped.

I have only now noticed that the rules require deviation to be less than 0.5%. Is it too late for me to update my submission to be compliant with the rules?

NC-8 (Durham, Chapel Hill) 1.062

Wake will be chopped. My inclination is to move Franklin in NC-10, and add a nibble of Wake to NC-8. NC-9 would be wholly in Wake and dominated by Raleigh. NC-10 would include the remnant of Wake, mostly in the south, but with an area in the northeast to link to Franklin.

So Mecklenburg, Wake, and Guilford, the three most populous counties would be chopped.



This is an updated map. This shifts Alamance into NC-7, and Caswell, Rockingham, and Stokes into NC-8. Franklin is shifted into NC-10. This is not depending on point contiguity, since NC-10 will take a substantial portion of Wake County along the eastern and southern borders. This is reasonably compact since it providing a partial donut around three sides of Raleigh. In addition NC-3 (Charlotte suburbs) is shown separate from NC-4 (Charlotte). Mecklenburg will be divided to connect the two parts of NC-3.

NC-1 (Appalachian, Asheville) 1.009
NC-2 (Western, Unifour) 1.000
NC-3 (Charlotte western/southern suburbs) 0.745
NC-4 (Charlotte) 1.254
NC-5 (Charlotte northern suburbs, Winston-Salem/Greensboro southern suburbs) 0.979
NC-6 (Greensboro/Winston-Salem) 1.144
NC-7 (Central, Greensboro, Raleigh fringes) 0.823
NC-8 (Northern, Durham/Chapel Hill) 0.998
NC-9 (Raleigh) 1.228
NC-10 (Raleigh suburbs and points east) 0.803
NC-11 (Southeast, Fayetteville) 1.005
NC-12 (Coast, Wilmington/New Bern etc.) 1.007
NC-13 (Albermarle, Rocky Mount) 1.004

Mecklenburg, Guilford, and Wake will be divided.

Mecklenburg will be 732,928 in NC-4. and 186,700 in NC-3 (this could conceivably be a partial donut following the I-485 loop)

Wake will be divided 733,172 in NC-9, 144,438 in NC-10, and 23,383 in NC-7. The portion in NC-7 will in the southwest bordering Chatham. The portion in NC-10 will be in the south, east, and west including the connection between Johnston and Franklin. NC-9 will be Raleigh-centric.

With optimal cuts, the standard deviation of deviations will be 0.69%.

UCCs:

Asheville UCC is 100% in NC-1, and forms 55% of the district.
Hickory-Lenoir-Morganton UCC is 100% in NC-2, and forms 45% of the district.
Charlotte UCC is entitled to 2.458 districts.
   NC-4 includes 41% of UCC, and UCC is 100% of district.
   NC-3 includes 33% of UCC, and UCC is 81% of district.
   NC-5 includes 26% of UCC, and UCC is 66% of district.
Greensboro-High Point/Winston-Salem UCCs are entitled to 1.366 districts.
   NC-6 includes 73% of UCC's, and UCC's are 100% of district.
   NC-5 includes 16% of UCC's, and UCC's are 23% of district.
   NC-7 includes 11% of UCC's, and UCC's are 14% of district.
Durham-Chapel Hill UCC is 100% in NC-8, and forms 55% of district.
Raleigh UCC is entitled to 1.459 districts.
   NC-9 includes 69% of UCC, and UCC is 100% of district.
   NC-10 includes 29% of UCC, and UCC is 43% of district.
   NC-7 includes 2% of UCC, and UCC is 3% of district.
Fayetteville UCC is 100% in NC-11, and forms 50% of district.

8 smaller single-county UCC's are in a single district. The largest, Wilmington UCC forms 28% of its district.

These show rough divisions of the split counties. In general, I was trying to make the Charlotte and Raleigh seats compact, rather than necessarily making the surrounding seats compact. I was also trying to avoid picking off areas that were largely black (avoid cracking black population). In Guilford, I ended up placing High Point in NC-7. You can bring in more white areas in the southwestern part of Greensboro, but then High Point stands out as prong down from the north, and looks more like race sorting.

Yes. But be sure to hurry. It is past the deadline, so they might decide not to evaluate it. It is probably a good exercise in any case to get used to other states.

The largest deviation is the +2.1% for NC-5. We can bring it into Guilford and adjust the other divisions Guilford and Wake.

Here's my map. I think it's the only one drawn that both preserves 4 VRA districts, and also has a 7R-6D split in PVI. (red for Democrat, blue for Republican)
