surface once they get past building 1. If that's not feasible due to grade limitations,then discharge using 'l splash blocks to the landscaped area between the buildings and then to the new CB. (Code provisions prohibit connecting new impervious areas directly into the combined sewer. Per the drainage mitigation requirements in the Stormwater Management Manual and as will be addressed in the Questionnaire, show the revised drainage proposal on the plans, again either on this site plan or on a separate drainage plan.) • Their contours do not match what we have in the City's GIS mapping system. Wetmore is shown about 15ft higher elevation than what is in the City records. (How were the contour lines on the site plan determined? The grading needs to be correct, including the stated finish floor elevation on the plans. If this does not match the City's required datum NAVD 88, it needs to be corrected.) They need to show inverts and slopes for the proposed side sewer and storm drain lines. They are j• responsible for making sure they have enough drop to make the connection to the sewer main. (Sewer lines must be a minimum of 6" from the duplex all the way to the main. This needs to be called out all of the side sewer laterals or clearly noted on the plans.) • They also need to show proposed grading on their plan so we can confirm this site will drain properly (and that finish floor elevation is appropriate). • I requested an inspection of the sewer in the alley—I don't see it in GraniteXp yet. Brian—this was SML3095H17, I requested a couple weeks ago. The sewer in the alley is old but doesn't have capacity issues. This pipe and the sewer line in Wetmore discharge to a pipe on 35th that has a 5-10 year level of service. (Again, this is the information we were waiting for before sending formal plan review comments to the applicant, however revised plans were submitted prior to us receiving this input.) The additional plan review comments that I have from a Public Works standpoint and that Planning has added, and which need to be addressed prior to resubmittal of plans are as follows: f•• A separate water service and meter needs to be shown for each building (one for each duplex). The water service line needs to be shown all the way from the main to the duplex unit itself, not just to the property line as currently shown on the plans. Each water service line needs to be clearly labeled with size and whether it is a new connection or an existing service to be reused or upgraded. This will help us calculate your utility permit fees and wrap up your permit package for issuance. The fence needs to be called out and labeled as a max 6' high wood fence, per EMC19.33G.040. • The above reference additional information in parentheses and blue text, after each of Amie's bullet points, are my other remaining comments. Plea a address the above remaining concerns and submit to the permit counter the following items: Plea • (2) copies of the revised site plan set • (2) copies of the completed Stormwater Management Questionnaire (ensure that the associated drainage and erosion control elements are shown on the site plan or separate plan sheets). J• (1)Transmittal Sheet addressed to Sabrina Fandler. I will route for review as appropriate and have Planning re-approve the plans. I will make this our first priority upon receipt of the resubmittal and can have this turned around within 2-3 days,with permit issuance eligible at that time as long as all items are correctly addressed.Again,we sincerely apologize for the delay in Plan Review Comments and will do everything we can to expedite this upon receipt. Please let us know if you have any questions while working on revisions. Thank you, 2/y
