This investigation is in conjunction with the redevelopment of the DCT Industries prupuffy, which was initially designated as Parcel i under the original Technical Intormation Report (I IR) tar the Plumbers and Pipetitters Regional Starmwater Retention Facility, dated June 1994 (see Appendix A.) Under the original design theru were six parcels within the drainage basin area, tutaling 44 acres and within that there was 25.5 acres of impervious surfaces. Each parcel was allocated a specific area of impervious surface, with the exception of the Metro Parcel. i his Parcel was nut given an allotment fur allowable tributary impervious surface. The tributary area tram this Parcel was 1.24 acres of pervious area. i he original Parcels were identified as Parcels 1, 2, 3, 4A and 4B and Metro. Using the city of Renton's web -based uIS data, the six parcel areas and imperviuus surfaces for each were checked to compare between the original allocation and current conditions. Copies of the GIS data used are included in this report. Fie total original allocation tar tributary impervioas saRaces was 25.5 acres that was divided amount five of the six parcels. As noted above, the Metro Parcel was not allocated to drain impervious surfaces to the regional stormwater shared facility. Of the five parcels with ar, allotment fur tributary impervious surfaces, three have a s, i allur area of impervious surface than what was allowed. I he overall existing impervioas surface area tributary to the facility totals approximately 24.06 acres, leaving a 1.44 acre balanus. E,&hibit A that fulluws piuvides a suiiimaiyy aica table. The existing regional stormwater shared facility consists of two ponds. I hese ponds are located on Parcels 2, 4A and 4B. The existing area of these ponds was checked to compare ponds total vulame to the uriyinal desiyn. The udyinal tupuyraphic survey maps were aced along with the tupugraphic uuntuars taRen tram the City's ul5 to develop an "existing" storage volume for these ponds. A summary table of the calculated volumes is provided as Exhibit J, and is entitled "Existing Pond Storage volumes" and s-ummary table This investigation also included a review of the City of Renton's current 2017 City of Renton Surface Water Design Manual which allows for "Shared Facility Drainage Plans" (SFDP's) whish the DCT Industries property and five uther NruNerrlies are pall of. This SFDP was originally aeveluped and approved 6y the Lity of Renton. Using the information within this report; there is about 1.44 acres of unallocated impervious sarfaoe area within the buanda�y of this shared facility drainage plan. 1 he proposed Du i industrial radevouprnent ut their parcei (which was originally noted as Parcel 1) is proposing to increase their impervious surface area by about 63,000 square feet or about 1.44 acres. This increase will fall ander the u, iyinal desiyn parameter of the pond storage and its pumps capacity. i hereture no change to the existing system is warranted for the redevelopment of this parcel. There is une item that does need to be addressed; There is an existing surface area from Monster Road SW which has been diverted to this regional stormwater facility which was not originally allucated to it. This roadway area a5uts Parcei 1, 2 and pail of 3 ana generWly bows trurn east to west around the 5ailding on Parcel 2 and on to the north pond area. The surface area from this roadway area is about 54,000 square feet or about 1.24 acres. As noted; this area was not alluuaTed to the "Shared Faoility Drainaye Plan" nor was it parr of the Reyiunal Detention Facility Pump Statim Agreement and Reciprocal Easements.

Shared facilities may be constructed ander a City-devuloped shared fauility drainaye plan or under an ayreement Between twu or more private developer's. 1. The regional or shared facility must be of adequate size and design to meet the carrent flow cuntrul requirements far the proposed project. Note: the current flow control requirements are those specified By Core Requirement # 3 at this manual unless superseded by other adopted area -specific flow control requirements per Special Requirement 0 (set Section 1.3.1). In some uabu5 where the current tlaw car itrol requirements differ trom those used to originally design the regional or shared facilities, additional analysis and possible retrofitting of the facility may be required to ensure adequate size and design. In other cases where the current flow control requirements are not significantly different or aru less stringent; adequate size and design may already Be ducamented by an adopted City basin plan or master drainage plan, and approved shared facility drainage plan, or a detailed drdinayu analysis appruvcd by the City for a separate permitted developed. 2. The regional or shared facility must be fully operational at the time of construction of the proposed prvjact. In the case of a shared facility, the proposed project must comply with the terms and conditions of all contracts, agreements; and permits associated with the shared facility. If the offsite facility is an existing City - owned facility, the City may charge a special ase fee equal to or based on the property value of the autentiun capacity Being used. 3. The conveyance system between the project site and the regional facility must meta the same uriivna specified fug direct disuharye to major rCuCiviny waicr except for Lriterion (a) (see "Direct Discharge Exemptiun" in Section 1.Z.3.1).

Where conflicts occur between the two, the drainage requirements of the adopted area -specific regulation shall supersede those in this manual... rrujects covered By SFuPs sHall demonstrate tHat the shared tacility will Be available by the time the project is constructed and that all onsite requirements are met. Project covered by a SFDP are still required to provide any onsite cur trols necessary to co,, ply with drainage reyaireme„ts not addressed by the shared tacility. He only an -site drainage requirement not covered by this shared tacility drainage pian is water quality, which will be addressed with the redevelopment of this project. i he DC i Industrial parcel was a partner in the development of this "'megiunal Detentior, Facility Pump Station Agreement and Reciprocal Agreement and was designated as Parcel 1 under the original Technical Information Report (TI R) for the Plumbers and Pipefitter Reyiunal Sturmwater Rete, iiion Facility dated June 1994 (see Appendi.& C).

Existing Pond Storage volumes The storage volume for this shared drainage facility was checked to determine any differ unues between the uriyinal dusiyned facility and what the cairent uunditicins represent. i Here were twu storage ponds defined; the nuffn and soath pends wfiiun are divided by an existing railroad spur which splits them. There is a 15" equalizing pipe shown on both the existing and developed basin maps between the two storage areas wMicM creates one large storage Mility. Under the original TIR, the storage volumes started at elevation 9 for both areas and uuminue r elevatiun 19. The total accumulated volume of both areas was determined to 6e 1,33U,453 cul5k; taut. The current GIS contour surface areas that can be developed were for elevations 16 up to 19 since there- are iu other contour below this shown. Te dater, iiine the surface contour areas ter elevations below 16, tMe original surveyed tupograpnic mapping in tMe original TIR were used (See Appendix A). A spreadsheet was developed to show the emstiny volume infurmatiu, alony with the new updated inturmation. It notes the topograpHic sartaces used fur earn elevation, either the original topographic maps or the City's GIS information. Elevations 17 and 19 were assumed bat were based oii existing GIS contours 16 and 18, since the City's GIS aues nut include tMe 1-fuut cuntoars. Using the above contour elevation surface area information, the total estimated accamalatad vulame uf buth punds is aruand 2,319,140 cubic feet. That amount is around 99.50/a ut the urigirial calcuiatud vuiume a, id tMat minur difference uan 6e attributed to a rounding error based on the data we have available to calculate this. Therefore our conclusion is that the current volume is essentially the same as the uriginal desiyn volume.
