RE:           Pamela Road Extension, Final Level II Site Plan Application
 
The Department of Public Services has the following comments.
 
1.      As noted by Woodard and Curran, the applicant is failing to meet the City’s Technical Manual standards for catchbasins design and castings.  If not already on the plans, please add a general note stating that “All proposed infrastructure located within the road right of way shall meet City of Portland Technical Manual standards.”
2.      The applicant is showing an eight inch Sch 40 for the gravity sanitary sewer.  This pipe is acceptable but so is SDR-35 which may be more cost effective and easier to install.  Be aware that per Technical Manual standards, the gravity sewer and manholes will require air and vacuum testing respectfully.
3.      The roadway surface area being drained to proposed catch basin’s one and two is quite large.  We are requesting the applicant place two additional basin at approximate station 3+00.  We would also like the applicant to consider an alternative catchbasin casting (not the City standard) to increase gutter drainage capture due to the street grade.  This could be a rectangular type casting by Neenah with a “L” or scoop style design.
4.      Please provide a detail of the drain manhole to be installed in Alice St.
