Default Need Water adjustment help for Dark Stout

So Far came up with this recipe for Russian Imperial Stout and been using the Ez water calculator to adjust my ideal water for Seattle, Wa soft water. My Water report right now is

Calcium-8.9 ppm
Magnesium- 1 ppm
Sodium- 6.8 ppm
Chloride- 4 ppm
Sulfate- 2 ppm
Alkalinity- 17.5 ppm

I know you want chloride and Sulfate to be even for a balanced beer, and I need to raise my Alkalinity higher for my Stout. Help is needed here, thanks everyone.

Just did a quick calculation on my ez tool calculator, let me know if this is ok? Can send a email of the calculator calculations of RA of 261 and mash ph is 4.91. Still feel like the RA is to low for a SRM of 55.5 but I cant raise anymore without getting to much Calcium and Sodium.

I get a SRM of 37.2 with my calculations. I have soft water in Atlanta as well: with stouts I tend to use larger portions of calcite and some gypsum.
