The following comments need to be addressed before the plans may be approved for construction. Our comments are summarized below: Cover Sheet, C1.0: Add the Conditions of Approval to the cover sheet.

Label location of Refuse Area Show pedestrian path from Mossman to building entrance. Show the revisions to the parking lot based on overhead power relocation. Label compact stalls with a “c”. Paving Details, C4.1: The sidewalk will need to be 6” thick at the driveway crossings. Add the following to the last note ….structurally adequate “with the City of Yelm approval.” Grading and Drainage Plan and Profile, C5.0: Show permanent fence around stormwater pond. (4’ black chain link) Catchbasin No. 1 offset appears in error. The grading may need to be revised slightly after the sidewalks are constructed through the accesses. Do not direct stormwater a crossed the sidewalk. The Aqua Swirl will out let will need to be shown straight not at an angle. May need to add a catchbasin to construct the angle. Grading and Drainage Notes and Details, C5.1: No Comments at this time. Utility Plan and Profile, C6.0 Is the second building going to need water or sewer services? Show step control panel and location, hose bib within 50 Feet of step tank, tank elevations not greater than 5 feet from invert to finish grade. The Carson box should be installed behind sidewalk. The side sewer can not come in the side of the tank. Both side sewers should connect before the tank. Show the grease trap size, type and elevations on the civil plans. The call out for less that 18” of separation between water and sewer plans can only be approved by the water or sewer inspector. It appears that a sewer air release is going to be required at the high point at approx. 47+50. If you change the hydraulically grade slightly you will not require an Air Release at this location. Complete sewer profile as needed. The connection point for the sewer should be at the alley on Rice St. The existing line is 4” in size. The water connection should be a hot tap not a cut in tee. Provide Fire Protection Plans showing how fire protection is being met. Is the 6” water line to the hydrant going to be sufficient? Where is the fire system double check going to be installed? What is the FDC fire line size? A Double check valve will be required to be installed behind the water meter from both domestic and irrigation.
