SUMMARY � � M Boeing Realty Corp is considering subdividing Parking Lots 3B and 6. These are the two blocks 4=� 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 subdivision lot that can `-� be served by gravity sanitary sewer. Each lot must be served by the existing C�ty of Renton sanitary �,a e..._ sewer main systems on N Eighth Street and Garden Avenue North. � The design cntena used to determine if gravity sanitary sewer was available to each new lot was as �=-� fo I I ows: cv • Any pnvate main or side sewer outside of the poss�ble building envelope was sloped at 0.5%. Maintaining this slope requires that those lines be a minimum of eight inches in diameter. • Sanitary sewer under the building footprint were sloped at 1.0% per the Uniform Plumbing Code Sect�on 708.0 Grade of Honzontal Drainage Piping. Section 708.0 allows a 1% slope when approved by the Administrative Authonty. 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% occurs at the setback line. In reality, the actual building footpnnt w�ll probably be further back than the setback line because of parking requirements and storm water management issues. • Finish (loor (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 footpnnt area avai]able to gravity se�ver service to a portion of the existing City of Renton sanitary sewer system � -t0 - 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 (loor elevation is gtven, the expected grade of the sanitary sewer system out side of the available lot building (ootpnnt, 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 descnption oC how the lot will connect tp the City sewer system.

Based on conversations with both Dave Christenson and Ronald Straka with the City of Renton it was determ�ned that �t would be feasible ro route the san�tary sewer for these lots through both the 48-inch and 72-�nch storm sewer systems. [n 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 cntena initially set is that the san�tary main needs to be above the 70 percent flow capaciry line of each pipe. Based on this cntena 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 1 and provide extension of the public sewer system to Lots 2 and 3 at a slope of 0.5%. • SHORT SUBDIVISION PARKING LOT 6—LOT 4: Sanitary sewer servicc to this lot w�ll require a manhole be installed on the ex�sting 20" City of Renton sanitary sewer ma�n on North 8th Street approximately 80 feet east of city Sanitary Manhole 61. � ''�' � ,, � � , � � � . . • � , • SHORT SUBDIVISION PARKING LOT 3B — LOT 1: This lot w�ll require a pubfic sanitary sewer main syslem exrendi�ig jrom Ihe 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.

N. IIased on conversacions 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 this lot 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 thc � " ��' sanitary pipe will need to be sleeved in ductile iron pipe. The other cnteria 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 20.8 Ceet in elevation or 4.2 feerabove the invert of the 72-inch pipe. The attached drawing shows this concept. • SHORT SUBDIVISION PARKING LOT 6 — LOTS 2 & 3: Lot 2 will rSquire the placement of side sewers over the top of the 72-inch and 48-inch storm drain lines. The side sewer will drop into the existing eight-inch City of Renton per the City of Renton rypical detail side sewer•nser detail. Lot 3 side sewer will also go over the 72-inch and 48-inch storm drain lines, and then will enter into the City Sanitary Manhole 158. • SHORT SUBDIVISION PARKING LOT 6—LOT 4: Sanitary sewer service to this lot will require a side sewer connection be installed on the existing 20-inch City of Renton sanitary r� sewer main on N. Eighth Street approximately 80 feet east of City Sanitary Manhole 61. iV ^ • SHORT SUBDIVISION PARIQNG LOT 3B—LOT 1: This lot will require the placement `T' of a side sewer into existing City of Renton sanitary sewer manhole 153 on Garden Ave. N. cr � The existing 12-inch City of Renton high-pressure water main may need to be routed under the "' new side sewer if a conflict is encountered. r�, � • SHORT SUBDIVISION PARKING LOT 3B — LOTS 2 AND 3: Lot 2 will have a side �__ sewer that will connect to the existing City of Renton Sanitary Sewer Manhole 155 on Garden ra Avenue N. Lot 3 will have a standard City of Renton side sewer connection to the City of '� Renton's 8" sewer main and Garden Avenue. An al�erno[e or additionol sani[ory sewer `''�' service to Lot 3 will require !he installalron of a side sewer into Ihe existing City oJ Ren�on sanilary sewer manhoJe 168 on N. 8[h Streel. • SHORT SUBDIVISION PARKING LOT 3B — LOT 4: Sanitary sewer service �o �his !ot wil! require a side sewer connection inlo �he exisling City oj Renton sanitary sewer approximalely 70 jeet norlh ojManhole 1 S3. 4. CONCLUSIONS Gravity 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 sign►ficant because: • The areas not covered are small. It is likely that any restrooms or other uses could be locatcd in a portion of thc building that has access. • Parking and storm water management issues will reduce the maximum size of the builJ�ng from that calculated to form the setback requirements alone. Parking and storm ��tcr � structures could be located in thesc areas where the sewer does not reach.
