SUMMARY �" Boeing Realry Corp is considenng subdividing Parking Lots 3B and 6. These are the two blocks 7 bordering Garden Avenue on the west and east sides, respectively between N. Park and N. Eighth `�" Street. Lot 6, to the east of Garden extends east to the rail tracks. This sewer availability study was performed by the Harris Group Inc. to determine the area of each new short subdiv�sion lot that can be served by gravity sanitary sewer. Each lot must be served by the existing City of Renton sanitary sewer main systems on N Eighth Street and Garden Avenue North. The design critena used to determ�ne if grav�ry sanitary sewer was available to each new lot was as follows: • Any private main or side sewer outside of the possible building envelope was sloped at O.S%. Maintaining this slope requires that those lines be a minimum of eight inches in diameter. • Sanitary sewer under the build�ng footpnnt were sloped at 1.0% per the Uniform Plumbing Code Section 708.0 Grade of Honzontal Drainage Piping. Section 708.0 allows a 1% slope when approved by the Administrative Authority. For purposes of this study, the possible building footpnnt area served by the sewer was conservatively calculated by assuming the transition from 0.5% slope to 1.0°/a occurs at the setback line. In reality, the actual building footprint will probably be further back than the setback line because of parking requirements and storm water management issues. • Finish floor(FF) elevation was determined for each lot based on site grades or as required to provide under building sanitary sewer coverage. • The highest allowable under building footprint sanitary sewer grade elevation was set at l'-6" (invert to top of finished floor) below the determined finish floor elevation to allow for finished plumbing turndowns and bends. Based on the design criteria above each new short subdivision lot has over 90 percent of its allowable building footprint area available to graviry se�ver service to a portion of the existing City of Renton sanitary sewer system � -�d- 2. DESCRIPTION OF FACILITY The following table provides a break down of the preliminary sewer design results for each new short subdivision lot. For each lot the determined building finish tloor elevation is given, the expected grade of the sanitary sewer system out side oC the available lot building footprint, the expected maximum length of sewer line under the building foot pnnt, the City of Renton sanitary sewer syste�n manhole in which the lot will connect to, and a description of how the lot will connect tp the City sewer system. . � SHORT LOT BUILDINC S,UVITARY AI,V(IAIU�I CITY SA�VITARY NOw IS CONhECT10N � SUBDIVISION YO.

Based on conversations with both Dave Christenson and Ronald Straka with the City of Renton it was determined that it would be feasible to route the sanitary sewer for these lots through both the 48-inch and 72-inch storm sewer systems. In each case a new manhole will need to be placed at each crossing, and the sanitary pipe will need to be sleeved in ductile iron pipe. The other critena initially set is that the sanitary main needs to be above the 70 percent flow capacity line of each pipe. Based on this criteria the new lot public sanitary sewer main will be crossing through the 72-inch storm sewer pipe at an elevation of approximately 20.4 feet in elevation or 3.8 feet above the invert of the 72-inch pipe. The attached drawing shows this concept. Once the public sanitary sewer main is on the east side of the 72-inch storm sewer a manhole will be placed to serve Lot l and provide extension of the public sewer system to Lots 2 and 3 at a slope of 0.5%. • SHORT SUBDMSION PARKING LOT 6—LOT 4: Sanitary sewer service to this lot will require a manholc be installed on the existing 20" City of Renton sanitary sewer main on North 8th Street approximately 80 feet east of city Sanitary Manhole 61. ' -11- • SHORT SUBDIVISION PARKING LOT 3B – LOT 1: This lot will require a publrc sanilary sewer main system ex�ending jrom �he existing City of Renton_Sanitary Sewer Manhole 153 on Garden Ave. N. The existing 12-inch City of Renton high-pressure water main may need to be routed under the new sewer if a conflict is encountered. • SHORT SUBDIVISION PARKING LOT 3B–LOTS 2 AND 3: These two lots will have a public sanitary sewer main system that will connect to the existing City of Renton sanitary ' sewer manhole 155 on Garden Ave. N. Outside of the building footprints of thcse two lots a � sanitary manhele will bc provide to convey the flow from each respective lot.

For each lot the determined building finish floor elevation is given, the expected grade of the sanitary sewer system out side of the available lot building footprint, the expected maximum length of sewer line under the building foot print, the City of Renton sanitary sewer system manhole in which the lot will connect to, and a description of how the lot w�ll connect to the City sewer system.

CONCLUSIONS Graviry sanitary sewer service is available to each of the lots in the proposed Short Subdivisions Parking lots 3B and 6. Building sewer service should be available in over 90% of the allow building footprint of each lot. In our opinion, the portions of the lot without coverage are not significant because: • The areas not covered are small. It is likely that any restrooms or other uses could be locatcd in a portion of the building that has access. • Parking and storm water management issucs will reduce the maximum size of the building from that calculated to form the setback reqnirements alone. Parking and storm w�icr � structures could be located in these areas where the sewet does not reach. � If you have any question regarding methodology,routings,or conclusion of this report please fccl t�ce to contact Hams Group Inc.at(206)494-9400. _13r • � . • ' • , . 5.
