My Redistricting Attempts, Part 1 -- Congressional Districts

The Utah Legislature's planned online redistricting program isn't up and running yet, so I used a tool I found last year called Dave's Redistricting Tool to create a congressional map. This is a first draft, and there are some limitations with the program (mainly, you have to use existing precinct lines).

So, here are the districts:

District A (blue):

Box Elder, Cache, Rich, Weber, Morgan Counties, plus Davis County except North Salt Lake City and Woods Cross west of 800 West and South of 1500 South.
Population: 690,868 (-102); 466,695 adults; 83.6% White, 11.3% Hispanic.

District B (red):

All of Tooele County; in Davis County: North Salt Lake City, Woods Cross west of 800 West and South of 1500 South.; in Salt Lake County: Magna, Salt Lake City, South Salt Lake, Millcreek Township, Holladay, Cottonwood Heights; plus the areas east of I-15 in Sandy, Midvale, and Murray (The area west of I15 and north of 4800 South in Murray is also in District B).
Population: 691,013 (+43); 505,242 adults; 73.6& White, 17.2% Hispanic.

District C (Orange):

Salt Lake County not in District B; Utah County: Cedar Fort, Eagle Mountain, Lehi, Saratoga Springs, Alpine, Highland, Cedar Hills, American Fork, Pleasant Grove, Lindon, Orem north of University Parkway.
Population: 690,879 (-91); 441,822 adults; 80.3% White, 13.2% Hispanic

District D (Green):

All areas not included in the other districts.
Population: 691,118 (+148); 479,096 Adults; 84.0% White, 10.2% Hispanic

Under my proposal, 3 counties (Salt Lake, Utah, Davis) are divided into more than one district (and it's impossible to not split Salt Lake County into more than one district).

In addition, only 5 cities (Woods Cross, Sandy, Midvale, Murray, and Orem) are split into two districts. The dividing line in Sandy, Midvale and part of Murray in the Interstate. The dividing line in Orem is a major thoroughfare.

So,what do you think?
