After poking around Google, I managed to find the flag of Sunchang County, Chŏllabuk-do (North Jeolla).
http://www.sunchang.go.kr/index.sko?menuCd=BA01002000000 gives a lot of symbolism of the symbol, but since my Korean is not that good, I will let the text from http://i-english.sunchang.go.kr/sunchang/symbols.html explain the symbol.
"This symbolizes the image of Sunchang's clean, beautiful natural environment, warmhearted people and historic local culture. It expresses the hope and the meaning of the new millennium in the 21st century. The colors of green, blue, red and white reflect the four beautiful seasons of Sunchang."
I based my drawing off of the design at http://www.sunchang.go.kr/join_images/images/sc_gun_sub/sunchanggunflag.jpg which mostly is the city symbol on a white background. I am not positive about the exact specifications.

To add some more information from http://www.sunchang.go.kr/index.sko?menuCd=BA01002000000 the Pantone colors are 354 C for green, 2738 C for blue and 431 C for red.
