Ecology home > Water Quality > Stormwater >Evaluation of Emerging Stormwater Treatment Technologies > Stormwater Treatment Technologies Types of Stormwater Treatment Technologies Approved through TAPE and CTAPE The following list separates the types of treatment technologies, defines them and lists manufacturers who make them. • Pretreatment • Oil Treatment • Enhanced Treatment • Phosphorous Treatment • Construction Site Ecology's use level designation is also listed as an acronym for each manufacturer: GULD - General Use Level Designation General Use Level Designation (GULD) technologies may be used Washington subject to use level designation conditions. CULD - Conditional Use Level Designation Conditional Use Level Designation (CULD) allows continued use of the technology for a specified time period during which field testing must be completed by the vendor and/or developer. Not all CULD technologies are required to conduct field testing. Units that are in place do not have to be removed after the specified time period. Use is subject to the use level designation conditions. PULD - Pilot Level Use Designation Pilot Use Level Designation (PULD) allows limited use of the technology to allow field testing to be conducted. PULD technologies may be installed provided that the vendor and/or developer agree to conduct field testing based on the TAPE at all installations. Governments covered by a municipal stormwater NPDES permit must notify Ecology when a PULD technology is proposed (form is available in TAPE documentation). Use is subject to the use level designation conditions. Pretreatment Pretreatment is generally applied to: Project sites using infiltration treatment I of ; 02 021 'low k �3 XM SJrnixva e:r'Freatment Technologies hap: !'►►,n►v.ecy.wa.;ov/Programs/wq/storm►►,ater/newtech/technolog ... • Treatment systems where needed to assure and extend performance of the downstream basic or enhanced treatment facility. Pretreatment is intended to achieve 50% removal of fine (50 micron -mean size) and 80% removal of coarse (125-micron-mean size) total suspended solids for influent concentrations greater than 100 mg/L, but less than 200 mg/L. For influent concentrations less than 100 mg/L, the facilities are intended to achieve effluent goals of 50 mg/L of fine and 20 mg/L of coarse total suspended solids. • Aqua Shield Aqua -Swirl Concentrator (GULD) • BaySeparator CULD@ • Environment 21 V2131 Treatment System (PULD)** • CONTECH Stormwater Solutions Inc.

Zimmerman Subject: RE: Renton Storm and Water System Improvement Project - Pan Abode Site Letter of Understanding - Update request Clint, I just wanted see if you could give me an update on the status of the letter of understanding approval. If getting the letter of understanding finalized is going to take another week or more, I wanted to see if it would be possible to get permission via email from the Port Quendall Company to proceed with submitting our permit application (SEPA/Shoreline permit) for the City project in advance of the letter of understanding being completed. The permission is needed because the City project includes the construction of the biofiltration swale and sidewalk on the Pan Abode site. Every week that the start of the City project permitting process is delayed, the start of the City project construction is delayed by one week. An email stating that "the City of Renton Surface Water Utility is authorized to submit permit applications that show work on the Pan Abode site that is owned by the Port Quendall Company, provided that final land rights (easements and dedications) are executed prior to the construction of the proposed improvements" is all that we need in order to start the City project permit review process. The idea is to use the email to allow the permit applications to be submitted and then place the letter of understanding in the permit file once it has been approved and signed. Please authorize the City to submit permit applications that includes work on the Pan Abode site this week, if it is going to take another week or more to finalize the letter of understanding. Please also provide your best estimate as to when Vulcan's approval of the Letter of Understanding will be completed. Thanks Ronald J. Straka, P.E.

Zimmerman Subject: RE: Renton Storm and Water System Improvement Project - Pan Abode Site Letter of Understanding Clint, The City is willing to accept the "non -binding" section that you added to the letter of understanding (attached). We recognize that until the final easement documents, right-of-way dedication and other documents are signed and recorded, there is no guarantee that the requested documents will be approved by Vulcan. We trust that Vulcan understands the importance of the items listed in the letter of understanding and will agree to approve and sign the formal documents for the easement needed for the storm water quality treatment biofiltration swale, the WSDOT storm system relocation and the dedication of the additional right-of-way necessary for the construction of the sidewalk on the Pan Abode site. Based upon our phone conversation today, you wanted the non -binding clause added to help in the review process on your end, but don't see any problems with the future approval of the easement documents. If possible please, authorize us to submit for permit application via email, so we can get the City project permitting started even though the full signature process of the letter of understanding has not be completed. Please continue with routing the letter of understanding with the non -binding clause for internal approval and return the signed letter to me or Steve Lee. We will have Gregg Zimmerman, Public Works Department Administrator, sign the letter and send you a copy. It is important that we expedite the signing of the letter of understanding, so we can start the permitting process for the City project and advance the project to construction, or provided us separate authorization to submit for permit application as requested above. We will be sending you the formal easement and right-of-way dedication documents for approval and signature by the Port Quendall Company by mid -July, which will need to be approved prior to construction bid advertisement currently scheduled for August 171h, in order to maintain the current project schedule. The City project is using public funds to make significant improvements (storm system, water system and curb, gutter and sidewalk improvements) that benefit and provide real value the Pan Abode property. We would not want to expend (waste) these funds on developing a project design that we cannot constructed due to not being able to obtain the easements and right-of-way needed for the construction of the public improvements. In our meeting we discuss this as an agreement in concept, pending the opportunity to review and approve the final easement and right-of-way dedication documents. The intent of the Letter of Understanding was to provide a high degree of confidence to the City that Vulcan would grant the required permission to submit permit applications showing work on the Pan Abode site an grant required land rights (easements and dedications) necessary for the construction of the public improvements. The City approved a right-of-way vacation that granted 12,100 sf of public right-of-way to the Port Quendall Company (Pan Abode site property owner) with the condition that an equivalent area be granted to the City for storm water management in the southwestern portion of the Pan Abode site. The approved vacation, once the required appraisal of the vacation area is completed and the vacation ordinance is approved, will legally obligates the property owner to grant area to the City for surface water management, otherwise the right-of-way vacation condition would not be satisfied and the right-of-way vacation will not be completed. As it stands City is requesting easement area that is less than the right-of-way vacation area. The right-of-way vacation and the relocation of the WSDOT storm system to allow the release of the existing WSDOT drainage easement on the Pan Abode site improves the value of the site by adding more developable area and removing an encumbrance that restrict development of the site. The right-of-way vacation and release of the existing WSDOT drainage easement on the Pan Abode site is needed in order for the Hawks Landing Hotel project to be a viable project. The primary items that the City needs at a minimum for construction of the City project includes the following: 1. Permission to submit permit applications that includes work on the Pan Abode Site as required by the SEPA checklist 2. An easement for the storm water quality treatment biofiltration swale 3. Dedication of addition right-of-way needed for the construction of sidewalk in the area south of the proposed Hawks Landing Hotel entrance. 4. A temporary construction easement to the City for the construction of the new 24-inch WSDOT storm system along the northern portion of the site 5. An easement to WSDOT for the new 24-inch storm system along the northern portion of the site. 6. Temporary construction easements and right -of -entry for construction of slopes and installation of catch basins The items related to right -of -entry and temporary construction easement needed for staging area are not critical items that we can work with Vulcan and the Hotel Developer on to resolve or work out alternatives location not on the Pan Abode site for construction staging. We look forward continuing to working with the Port Quendall Company (Vulcan) as needed to gain the approval the primary items in the letter of understanding that the City needs at a minimum for the construction of the City project and to ensure that the Hawks Landing Hotel project is viable.

The electronic copy of the letter understanding that the City sent you on 5/11/10 is attached for you to revise to be in the form that is acceptable to Vulcan. The most critical items in the letter of understanding that are needed is the approval for the City to submit permit applications that includes work on the Pan Abode Site and a commitment to grant the right-of-way dedication and easements needed for the construction of the biofiltration swale, sidewalk and storm system construction on the Pan Abode site. The letter of understanding will give us the assurance that we can proceed with the permitting and final design of the project with confidence that the necessary final easements and right-of-way dedication documents would be approved by Vulcan prior to the City advertising the project for construction. Please revise the letter as necessary to satisfy your needs and provides a red -lined version showing the changes so we can see how it has been changed to ensure that the revisions will satisfy our needs. If there is anything I can do to assist you in getting approval of this letter of understanding, or if you want to discuss proposed changes to the letter of understanding, please feel free to contact me.

After subsequent internal City discussion with Transportation, Planning and Development Services Divisions, it was determined that the addition area needed for sidewalk really should be granted to the City through a right-of-way dedication and not through an easement. The Hawks Landing Hotel Hearing Examiners report required that the site plan be revised to reflect the location of the 10-ft landscape strip and 12-foot sidewalk along the street frontage for the 3.07 acre development site. This sidewalk area would then normally be dedicated to the City as a condition of the permit approval for the Hotel project. Below is an email message from Vanessa Dolbee explaining the requirement for dedication, how it doesn't impact the hotel development plans or the future development plans on the portion of the Port Quendall Company property south of the proposed Hotel project, with respect to land use density and setback requirements. Since the City water and storm system improvement project is moving forward prior to the Hotel project, we would like to change our request for the additional sidewalk area south of the Hotel project site that is needed from the property owner, to be dedicated to the City as right-of-way instead of an easement. This would allow the City to construct the sidewalk south of the Hotel project entrance. The construction of the sidewalk and dedication of any additional right-of-way to the City would be required anyway when this portion of the site is developed in the future. It is just happening sooner since the City is constructing frontage improvements that would normally are constructed by any future development on the southern portion of the site frontage. The right-of- way dedication is also in exchange for the City's approval of a public right-of-way vacation at the northern entrance. The sidewalk area (3,282 sf) needed for the construction of the sidewalk as part of the City project (south of the Hotel entrance driveway) can be dedicated by itself and then the sidewalk area that will be constructed by the Hotel can be dedicated when the Hotel project permit is approved. Alternatively, the total area on the Port Quendall Company property that is needed for sidewalk along the full frontage of the Port Quendall Company site (7.24 acre site), could be dedicated at one time, but the responsibility for the construction of the sidewalk would still remain the same. The combined dedication of the total area on the Port Quendall Company property needed for sidewalk would be the recommended approach, but we would be ok with just dedicating the area that is needed for the City project sidewalk construction south of the Hotel project entrance. We will revise the attached figure that shows the sidewalk area to reflect that it is a dedication instead of an easement along with our write-up regarding the land rights needs. We intend to make this change and send you a draft letter of understanding with the updated land rights needs description and exhibit. If needed we can discuss any concern you may have regarding the dedication of the additional area on the site needed for sidewalk. Please let me know if you would prefer to do one dedication for the total sidewalk area needed on the Port Quendall Company property, or would prefer to keep the dedications separate.

Utility Engineering Supervisor City of Renton Surface Water Utility Renton City Hall - 5th Floor 1055 South Grady Way Renton, WA 98057-3232 Email: rstraka@rentonwa.gov Ph: 425-430-7248 From: Vanessa Dolbee Sent: Tuesday, April 27, 2010 10:08 AM To: Ronald Straka; Steve Lee; Neil R. Watts Cc: Chip Vincent Subject: Easements vs. Dedication Lake WA Blvd. To All At the time of development of the HL hotel, dedication would be required for the street frontage improvements on the northern 3.07 acre site. Dedication of the necessary right-of-way for the 10-foot planter strip and 12-foot sidewalk as required by the hearing examiner for the approval of the HL hotel, would also be required at the time of development of the southern portion of the Pan Abode site. Dedication of the full frontage width would not impact the potential for the future development of the remainder of the Pan Abode site. This is due to the properties location within the COR zone. The COR zone development standards do not stipulate specific setbacks; setbacks is determined through the site plan review process. As such, the dedication of a strip of property that fronts Lake Washington Boulevard, would not negatively impact future development plans for the area. Furthermore, the dedication would theoretically move the existing property line east, bringing it closer to the existing warehouse buildings located on the site. The movement of the property line would not impact the existing warehouse buildings in terms of conformance with development standards. A second concern may be that the dedication would reduce the amount of land area that could be used to calculate maximum density for the subject site. The City uses net density to determine minimum and maximum residential density in any zone. When calculating net density, the City subtracts land area that includes, access easements, required dedications, and critical areas. If the City was not financing the improvements for the south portion of the Pan Abode site it would be the responsibility of the developer to construct these improvements. As such, during the review of any residential development for the south portion of the Pan Abode site the City would subtract the land area that would be required to be dedicated at the time of development. Therefore, the land area needed to construct the planned improvements now, would not be included in density calculations in the future therefore dedicating the land area now would not have an adverse impact on the maximum density of the site in the future. Moreover, the dedication of the frontage area would be required at some point in the future in order for the subject property to be redeveloped. As such a dedication now would provide a cleaner transition for the City in terms of maintenance and construction of the planned frontage improvements.

Delays in gaining easement signatures may result in this project being constructed next year and possibly result in increased construction costs from contractors or even the state reducing/cancelling the grant appropriation for the storm and water system improvement project. The City is currently expediting the design, but needs the following easements and approvals from the property owner (Port Quendall Company) in order to continue with the project: 1. The City of Renton requests approval from the Port Quendall Company to sign as the project representative for Environmental Review, Shoreline Review, and JARPA Application. This is needed because the project proposes to construct improvements in areas outside of City -owned right-of-way on property owned by the Port Quendall Company. The improvements would be constructed in easement areas as described below. After the Port Quendall Company approval is granted, the City shall sign the Affidavit of Ownership on these applications and move forward with the Lake Washington Boulevard North Storm and Water Improvement project. 2. The City has completed the 35% plan set design which includes the wet biofiltration swale facility to treat surface water runoff from portions of Lake Washington Boulevard North. (See easement needs exhibit attached for the location of the biofiltration Swale.) The wet biofiltration swale and maintenance access area needed is approximately 6,832 square feet and is located mostly within the 200-feet shorelines setback of May Creek. During the City of Renton vacation for the access road on the north portion of the site, the City vacated 12,100 square feet of uplands right-of-way area with a condition of release that included provisions for a City storm water treatment facility in the southwest portion of the parcel (see City of Renton VAC file #09- 001). Note that construction of the biofiltration swale will require approximately six to seven feet of existing asphalt in the southwest area to be removed. 3. Approximately 3,283 square feet of sidewalk easement is needed for the project to construct the sidewalk south of the proposed Hawks' Landing south entryway (see hatched area in attached easement exhibit). This area is required as part of the 12-feet wide sidewalk width H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-3531 Lake Washington Blvd -Hawks' Landing\1201 Easements\Lake_Wash_Blvd_ESMTbulletneeds_100325.docx\STLtp conditioned by the Hearings Examiner on August 25, 2009. (See City of Renton File No. LUA 09- 060, ECF). If this easement area is not granted, then the hotel developer shall be responsible for construction of the south sidewalk. In addition, the construction of the sidewalk and wet bio- filtration swale access areas will impact the southwest foundation of the existing building on - site. The demolition of at least a portion of the existing building to eliminate the potential effects of soil foundation uplift of the building when the City project is constructed needs to be understood by the Port Quendall Company. The whole existing building has to be demolished as part of the Hawks' Landing Hotel project construction. Our goal is to coordinate construction of the City's project with the Hawks' Landing Hotel project construction so that the existing building is demolished prior to the City's project construction occurs in the area of the building. 4. The City's proposed new 24-inch WSDOT storm pipe on the north end of the site will require a new easement to WSDOT and the City of approximately 1,960 square feet. The existing storm pipe easement area is under the proposed new Hawks' Landing hotel building and the City will be constructing the new 24-inch storm pipe system in a new location that will not conflict with the proposed hotel. The City needs to be included in the easement in order to construct the storm pipe. An appraisal of the value of the existing WSDOT storm easement area, along with the appraisal value of the new WSDOT easement area plus the value of the City constructed new storm pipe in the new WSDOT easement area, will be performed and compared to each other to determine if any compensation for the release of the existing WSDOT easement is required as part of the WSDOT release of easement real estate process. Our goal is to have the value of the existing WSDOT easement being released equal to the value of the new WSDOT easement area plus the new storm system value. This would eliminate the need for the property owner or the Hawks' Landing Hotel developer to have to provide any compensation to WSDOT for the release of the existing WSDOT easement. (See easement exhibit for existing and proposed easements.) The existing WSDOT easement area is recorded as #7811221071 and is currently in the appraisal process started by the City, which the City is funding from the state grant funds ($10,000). Approval by the Port Quendall Company of the new WSDOT easement location, in order to provide WSDOT the new storm easement and assist in vacating the existing WSDOT drainage easement, is needed for the City to construct the WSDOT drainage connection. In addition, the releases of the existing WSDOT storm easement will un-encumber land under the proposed Hawks' Landing hotel building. WSDOT also needs consent from the existing the Port Quendall Company or hotel developer on who will assume payment responsibilities for any compensation for their release of the existing WSDOT easement, if there is any compensation required. The need for compensation will be determined after appraisals are completed and negotiations with WSDOT. This information is needed by the WSDOT regional headquarters prior to their progressing with the real estate valuation process that is needed for the release of the easement. 5. A temporary construction easement will be needed from the back of sidewalk from south of the proposed south entry in order to construct a fill slope (2:1) behind the sidewalk and to construct a catch basin to collect localized building and land runoff west of the existing building. A second temporary construction easement will be needed east of the proposed bio-swale to construct H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-3531 Lake Washington Blvd -Hawks' Landing\1201 Ease ments\Lake_Wash_Blvd_ESMTbuIletneeds_100325.docx\STLtp the drainage connection for existing runoff that currently is piped into the Lake Washington Boulevard North ditch. Finally, the last temporary construction easement for staging, constructing the WSDOT connection under the north access road and material deliveries will be needed. The staging area can be moved to an area that will not disrupt the property owner's operation for the site. The City's Storm and Water System Improvement construction plans are currently at 35% design. The City will not start the permitting process to proceed with the 60% design plans until a determination of the WSDOT easement needs are agreed upon by the property owner. The 60% design plans are needed by WSDOT in order for them to move forward with their easement release appraisal process. A written assurance by the Port Quendall Company for the following items is needed: • The Port Quendall Company owner agrees to authorize the City of Renton to submit permit applications for Environmental Review, Shoreline Review, and JARPA Application that includes work on the privately -owned property (bio-filtration swale, new 24" storm system in a new WSDOT easement, and sidewalk). • The Port Quendall Company agrees to grant the City of Renton the required easement for the bio-filtration swale and sidewalk area to be located on private property south of the proposed Hawks' Landings Hotel project. In addition, the Port Quendall Company will grant a temporary construction easement for the new 24-inch storm system on the north end of the property, to be constructed by the City and located in a new WSDOT easement. The City would provide the Port Quendall Company the final easement documents to review and approve prior to the advertisement of the City project for construction. • The Port Quendall Company agrees to grant WSDOT a new easement of approximately 1,960 square feet in exchange for WSDOT releasing the existing WSDOT easement located under the proposed Hawks' Landing Hotel building. • The Port Quendall Company or the Hawks' Landing Hotel developer agrees to assume payment responsibilities for any compensation required by WSDOT for the release of the existing WSDOT easement on the property, if there is any compensation required, which will be determined after appraisals are completed and negotiations with WSDOT. • The Port Quendall Company agrees to grant the City temporary construction easements, the construction of back of sidewalk slopes, and installation of storm system catch basin to provide drainage to the private property.

I want to use this meeting to provide whatever information that Clint Chase needs as part of his role in facilitating Vulcan's involvement and cooperation. Below are the initial questions that I received from Clint Chase pertaining to the project memo that you sent out. I responded to these questions as completely as I could and in a number of cases there were questions that I felt would be better dealt with at a face to face meeting. I will see you at 11:00 am Wednesday and Clint Chase has already confirmed his availability. Please let me know what floor and room that the meeting will take place in. Thanks! Dan Mitzel From: Clint Chase To: spencer@alpertcapital.com To: 'Dan Mitzel' Subject: Pan Abode - Bioswale Questions Sent: Apr 13, 2010 11:38 AM Steve and I met yesterday with one of our development managers to discuss the bioswale/easements matter posed by you and the City of Renton. We don't see any serious issues, but we had a few questions about the bioswale. We want to understand some of the issues in more detail before we talk with the Renton people. 1. What exactly is the bioswale for? Storm water treatment? Yes the Swale is for storm water treatment. 2. In addition to treating water from Lake Washington Blvd., would it treat surface run-off water from the Pan Abode property and the eventual Hawk's Landing development project? The swale will be constructed to handle all new impervious surface area that is created as a result of the widening of Lake Washington Blvd and it will treat a minor amount of storm water at the entrance into the Hawks Landing project. We have discuss with the the City the possibility of expanding the swale to the north to allow for treatment oof a significant portion of the storm water from our project and it does appear to be feasible to expand the swale in the future as part of our storm water treatment plan. The swale will not be treating any of the existing runoff from the Pan Abode site. 3. What exactly is it cleaning? The swale will treat the storm water by removing sediments and other pollutants to a level of treatment that meets the City of Renton, King County and DOE standards. 4. Once treated, where does the discharge product go and how does it get there? The discharge point is into the existing ditch in close proximity to the ditches confluence with May Creek. 5. What happens if it overflows? How is that addressed? There is a bypass structure and pipe that allows for excessive flows to bypass the swale and go into May Creek. A 6. How will it be finished? Landscape? Hardscape? These details are not yet worked out and will be forthcoming as the City continues the design of the project. * 7. Since it's the "front door" to the project, how will it look will it look when complete? We will be very involved in making sure that the swale is in no way a detracting factor for the Hawks Landing project. -7 -J —"- 8. We would like to know how the greater storm water system works around the current property. This question should be addressed at a face to face meeting with Steve Lee at the City of Renton. 9. Who maintains the bioswale once completed? Will this be addressed in the easement document? The city of Renton will have full maintenance responsibility. 10. Is the project designed to handle storm water from surrounding property? What landowners benefit? The swale will not benifit any other private property owner. ,J- 11. Can you confirm the timing of construction? This summer? At this time I believe that the City wants to build it in late summer / early fall of 2010. A meeting with the City will provide additional information concerning timing of construction. 12. What exactly does Renton want from us right now? In what form? I believe that the last part of the memo from the City spells out what needs to happen. A meeting with the City will provide additional details. I do know that the City needs to move quickly to meet their desired schedule so the sooner we meet the better. 13. Can you confirm that the current understanding with Renton is that it will deed to PQC the excess land at the north end of the property (approx. 12,000 S.F.) in exchange for PQC granting the easements described in the proposal Spence gave us last week. Conceptually the plan is to swap values and an appraisal process will determine the values of each parcel and easement. Once these values are agreed to by all parties then the final determination of who is writing a check to who will be determined. Hawks Landing LLC will be paying for any amount owed by the property owner if there is any amount owed. 2 Thanks for helping us understand this in more detail.

Delays in gaining easement signatures may result in this project being constructed next year and possibly result in increased construction costs from contractors or even the state reducing/cancelling the grant appropriation for the storm and water system improvement project. The City is currently expediting the design, but needs the following easements and approvals from the property owner (Port Quendall Company) in order to continue with the project: 1. The City of Renton requests approval from the Port Quendall Company to sign as the project representative for Environmental Review, Shoreline Review, and JARPA Application. This is needed because the project proposes to construct improvements in areas outside of City -owned right-of-way on property owned by the Port Quendall Company. The improvements would be constructed in easement areas as described below. After the Port Quendall Company approval is granted, the City shall sign the Affidavit of Ownership on these applications and move forward with the Lake Washington Boulevard North Storm and Water Improvement project. 2. The City has completed the 35% plan set design which includes the wet biofiltration Swale facility to treat surface water runoff from portions of Lake Washington Boulevard North. (See easement needs exhibit attached for the location of the biofiltration Swale.) The wet biofiltration Swale and maintenance access area needed is approximately 6,832 square feet and is located mostly within the 200-feet shorelines setback of May Creek. During the City of Renton vacation for the access road on the north portion of the site, the City vacated 12,100 square feet of uplands right-of-way area with a condition of release that included provisions for a City storm water treatment facility in the southwest portion of the parcel (see City of Renton VAC file #09- 001). Note that construction of the biofiltration Swale will require approximately six to seven feet of existing asphalt in the southwest area to be removed. 3. Approximately 3,283 square feet of sidewalk easement is needed for the project to construct the sidewalk south of the proposed Hawks' Landing south entryway (see hatched area in attached easement exhibit). This area is required as part of the 12-feet wide sidewalk width H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-3531 Lake Washington Blvd -Hawks' Landing\1201 Ease ments\Lake_Wash_Blvd_ESMTbulletneeds_100325.docx\STLtp conditioned by the Hearings Examiner on August 25, 2009. (See City of Renton File No. LUA 09- 060, ECF). If this easement area is not granted, then the hotel developer shall be responsible for construction of the south sidewalk. In addition, the construction of the sidewalk and wet bio- filtration swale access areas will impact the southwest foundation of the existing building on - site. The demolition of at least a portion of the existing building to eliminate the potential effects of soil foundation uplift of the building when the City project is constructed needs to be understood by the Port Quendall Company. The whole existing building has to be demolished as part of the Hawks' Landing Hotel project construction. Our goal is to coordinate construction of the City's project with the Hawks' Landing Hotel project construction so that the existing building is demolished prior to the City's project construction occurs in the area of the building. 4. The City's proposed new 24-inch WSDOT storm pipe on the north end of the site will require a new easement to WSDOT and the City of approximately 1,960 square feet. The existing storm pipe easement area is under the proposed new Hawks' Landing hotel building and the City will be constructing the new 24-inch storm pipe system in a new location that will not conflict with the proposed hotel. The City needs to be included in the easement in order to construct the storm pipe. An appraisal of the value of the existing WSDOT storm easement area, along with the appraisal value of the new WSDOT easement area plus the value of the City constructed new storm pipe in the new WSDOT easement area, will be performed and compared to each other to determine if any compensation for the release of the existing WSDOT easement is required as part of the WSDOT release of easement real estate process. Our goal is to have the value of the existing WSDOT easement being released equal to the value of the new WSDOT easement area plus the new storm system value. This would eliminate the need for the property owner or the Hawks' Landing Hotel developer to have to provide any compensation to WSDOT for the release of the existing WSDOT easement. (See easement exhibit for existing and proposed easements.) The existing WSDOT easement area is recorded as #7811221071 and is currently in the appraisal process started by the City, which the City is funding from the state grant funds ($10,000). Approval by the Port Quendall Company of the new WSDOT easement location, in order to provide WSDOT the new storm easement and assist in vacating the existing WSDOT drainage easement, is needed for the City to construct the WSDOT drainage connection. In addition, the releases of the existing WSDOT storm easement will un-encumber land under the proposed Hawks' Landing hotel building. WSDOT also needs consent from the existing the Port Quendall Company or hotel developer on who will assume payment responsibilities for any compensation for their release of the existing WSDOT easement, if there is any compensation required. The need for compensation will be determined after appraisals are completed and negotiations with WSDOT. This information is needed by the WSDOT regional headquarters prior to their progressing with the real estate valuation process that is needed for the release of the easement. 5. A temporary construction easement will be needed from the back of sidewalk from south of the proposed south entry in order to construct a fill slope (2:1) behind the sidewalk and to construct a catch basin to collect localized building and land runoff west of the existing building. A second temporary construction easement will be needed east of the proposed bio-swale to construct H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-3531 Lake Washington Blvd -Hawks' Landing\1201 Easements\Lake_Wash_Blvd_ESMTbulletneeds_100325.docx\STLtp the drainage connection for existing runoff that currently is piped into the Lake Washington Boulevard North ditch. Finally, the last temporary construction easement for staging, constructing the WSDOT connection under the north access road and material deliveries will be needed. The staging area can be moved to an area that will not disrupt the property owners operation for the site. The City's Storm and Water System Improvement construction plans are currently at 35% design. The City will not start the permitting process to proceed with the 60% design plans until a determination of the WSDOT easement needs are agreed upon by the property owner. The 60% design plans are needed by WSDOT in order for them to move forward with their easement release appraisal process.

A temporary construction easement will be needed from the back of sidewalk from south of the proposed south entry in order to construct a fill slope (2:1) behind the sidewalk and to construct a catch basin to collect localized building and land runoff west of the existing building. A second temporary construction easement will be needed east of the proposed bio-swale to construct H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-3531 Lake Washington Blvd -Hawks' Landing\1201 Easements\Lake_Wash_Blvd_ESMTbulletneeds_100325.docx\STLtp the drainage connection for existing runoff that currently is piped into the Lake Washington Boulevard North ditch. Finally, the last temporary construction easement for staging, constructing the WSDOT connection under the north access road and material deliveries will be needed. The staging area can be moved to an area that will not disrupt the property owner's operation for the site. The City's Storm and Water System Improvement construction plans are currently at 35% design. The City will not start the permitting process to proceed with the 60% design plans until a determination of the WSDOT easement needs are agreed upon by the property owner. The 60% design plans are needed by WSDOT in order for them to move forward with their easement release appraisal process. A written assurance by the Port Quendall Company for the following items is needed: • The Port Quendall Company owner agrees to authorize the City of Renton to submit permit applications for Environmental Review, Shoreline Review, and JARPA Application that includes work on the privately -owned property (bio-filtration swale, new 24" storm system in a new WSDOT easement, and sidewalk). • The Port Quendall Company agrees to grant the City of Renton the required easement for the bio-filtration swale and sidewalk area to be located on private property south of the proposed Hawks' Landings Hotel project. In addition, the Port Quendall Company will grant a temporary construction easement for the new 24-inch storm system on the north end of the property, to be constructed by the City and located in a new WSDOT easement. The City would provide the Port Quendall Company the final easement documents to review and approve prior to the advertisement of the City project for construction. • The Port Quendall Company agrees to grant WSDOT a new easement of approximately 1,960 square feet in exchange for WSDOT releasing the existing WSDOT easement located under the proposed Hawks' Landing Hotel building. • The Port Quendall Company or the Hawks' Landing Hotel developer agrees to assume payment responsibilities for any compensation required by WSDOT for the release of the existing WSDOT easement on the property, if there is any compensation required, which will be determined after appraisals are completed and negotiations with WSDOT. • The Port Quendall Company agrees to grant the City temporary construction easements, the construction of back of sidewalk slopes, and installation of storm system catch basin to provide drainage to the private property.

Since there may not be sufficient room behind the new westerly bend due the vicinity of the 12" high pressure gas line, to accommodate a much larger block for the 90 degree bend, we will need to install a new dead -man block on the east side of the new bend. The south side of the bend will be restrained with shackled rods to the existing dead -man block south of the connection point. See attached sketch. I am also attaching a copy of the City's special detail for a dead -man block, which you can either show on the plan sheet, or insert it in the back of the specifications book along with other related standard details. As you know, the static pressure is about 120 psi, the test pressure will be 270 psi, and as such the size, and bearing area of the thrust block for the easterly bend will be significantly increased from changing the 22 degree to a 90 degree bend. Let me know if you have any questions, Sincerely, Abdoul Gafour Water Engineering Supervisor City of Renton Public Works 1055 S Grady Way Renton, WA 98057 425-430-7210 agafour@rentonwa.gov From: Stacey Clear [mailto:sclear@g-o.com] Sent: Tuesday, August 31, 2010 11:50 AM To: Abdoul Gafour Cc: Steve Lee Subject: Hawk's Landing Hello Abdoul, Would you entertain putting a 90 degree bend at Station 11+15 (south end of the Hawk's Landing project) so that we could just do a straight sawcut across the concrete panels to the east side of the road instead of having to cut them at an angle?

Barry Baker, P.E. DATE: July 15, 2010 SUBJECT: Design Issues for Hawk's Landing Gray & Osborne held a Quality Assurance/Quality Control review of the project on July 14, 2010. In this process, senior level staff not directly involved in the process, reviewed the plans and specifications and provided comment and feedback. The meeting was conducted with Barry Baker, Stacey Clear, Tim Osborne (Senior Transportation Manager at G&O), and Roger Kuykendall (Stormwater and City Engineer for various G&O clients). Since these senior level staff members have not been a part of all the discussions with the client, some issues raised may have already been addressed or direction was already provided by the client. As a result of our internal quality assurance/quality control meeting, we have listed a number of concerning issues related to the design of the Hawk's Landing project as it exists today. The issues raised are as follows. CONCERNS Concrete Panels We need to verify if concrete panels exist and what depth the concrete is likely to be in the roadway. Is there any geotech information in close proximity (i.e the Ripley Lane project, WSDOT I-405 improvements, bridge installation) that confirms that concrete panels exist under the roadway and where these panels might be located within the road prism? We note the 1991 Earth Consultants Report has no data on Lake Washington Boulevard. It is presumed by looking at the survey that the existing utilities are located in their current alignment to avoid concrete panels in the roadway. This forces the water main to either be in the concrete panels or off the roadway. It will be costly to place the water main within the roadway if concrete panels exist, both in sawcutting and in restoration. We are unaware of the city standards on trenchlroad restoration through concrete panels but in doing a quick cost estimate based on the assumption of filling the trench with bankrun gravel, 18" of CDF and then 6" of HMA on top of the CDF, we find that the water main would cost approximately $33,000 more if concrete panels were present. The July 20, 2010 Page 2 additional cost involves primarily the addition of CDF and extra sawcutting depth. For our estimate, we used CDF and extra sawcutting prices from jobs we are currently working on. Although not included in the price above, removal of structures and obstructions and traffic control would be greater as well. If the city standard is to replace the entire concrete panel, the cost would be significantly more. Utility conflicts Gas Main Conflict At Station 11+10, where the new fire hydrant is supposed to be located, it appears there is a conflict with the 12" high pressure gas main and the 6" fire hydrant stub. We would propose moving this fire hydrant to a location on the east side of the road. One alternative is to replace the existing 8" main that crosses the road with a new 12" main. We would then keep the 12" water main on the east side of road, out of the concrete panels in the roadway for the remainder of the project (to Station 25+35). The water main could follow the new curb line. To maintain the city's separation requirement, the stormwater pipe would have to move further east, closer to the existing ditch line. Fiber Optics At Station 20+55, a 12" DI water main stub is intended to cross over the fiber optics located in this area. Fiber optics are always difficult to contend with. If the water main were placed under the curb line, we would avoid the fiber optics. Drainage along Roadway Due to the flat elevation along the road between Station 17+50 and 21+50, the City may need to provide an additional type 1 catch basin/inlet placed along this curb alignment to ensure drainage of this flat area. If needed in the future, Inserta tees could easily be used on the 24" pipe if the City needed to go in after the project was completed to help eliminate ponding in an unforeseen low spot. Pervious Concrete Sidewalk Due to the vehicle weight restrictions, we recommend leaving driveway/maintenance access entrances as regular, non -pervious concrete. In addition, we wanted to make the City aware that pervious concrete sidewalks typically cost at least 10% more than non - pervious concrete sidewalks and are usually not as visually appealing as typical sidewalks due to the large voids present. Likewise, drainage will seep under the sidewalk and is likely to continue to flow to the area where it currently goes today (i.e. toward the proposed wet bioswale). July 20, 2010 Page 3 RECOMMENDATIONS We are aware that some of these issues have been discussed previously with the City. The recommendations from the QA/QC team are: • Confirm the presence/absence of concrete panels. _` f (' • If the panels are present, move the new 12" water main to the east side of the road, away from the presumed concrete panel and under the proposed curb line. This recommendation is based on the extensive production cost of working in concrete panels, restoration requirements, and due to the indicated utility conflicts. • Due to the separation requirement, the storm water pipe would move to the existing ditch line. • Provide standard concrete driveway ramps through the sidewalk for driveway/maintenance access. • Complete a proposed curb and gutter design for number and placement of catchbasin/inlets and as a result, multiple type 1 catch basins may need to be added between Section 17+50 and 21+50. ** 5 ? ct S � 6 4 e, fk- .

In addition, we wanted to make the City aware that pervious concrete sidewalks typically cost at least 10% more than non - pervious concrete sidewalks and are usually not as visually appealing as typical sidewalks due to the large voids present. Likewise, drainage will seep under the sidewalk and is likely to continue to flow to the area where it currently goes today (i.e. toward the proposed wet bioswale). Steve Lee From: Vanessa Dolbee Sent: Tuesday, August 17, 2010 9:06 AM To: Steve Lee Subject: RE: Lake Washington Blvd: Planning and DSD comments This all sounds great. Thank you. From: Steve Lee Sent: Tuesday, August 17, 2010 8:45 AM To: Vanessa Dolbee Subject: RE: Lake Washington Blvd: Planning and DSD comments Reponse to your comments: 1. Sidewalk detail will be supplemented with a cross section detail with width of landscape strip. It was noted in my redline comments to them already. 2. This was the 60% plan submittal, before landscaping was forced on us a few weeks ago by Parks and Planning. We are working the addendum to get the LS architect on board that Parks wants. The LS architect Parks suggested has been scoping the work to ensure what is needed is provided. The last second addition of LS (not in SEPA submittal remember) may cause us to delay the project bid opening... It will be included in the 90% plan submittal. We cannot redo the 60% plan submittal since that would require a re -scope and increased consultant fees and additional delays. 3. The sidewalk easement line follows the street curbing, not the sidewalk. The sidewalk location was suggested by HL and approved by Transportation, but the ROW dedication line follows the curb offset of 0.5 feet for curb width, 12 feet for landscape width (does not matter if there is an entrance of not since we do not fully know if HL will fund their project, then we will need that full offset), 10 feet for sidewalk and 1 feet for back of sidewalk. That is why the different location... which follows the curb, not the sidewalk. Note that landscaping tapers to the proposed, future south HL entryway... Therefore the difference in the ROW dedication line and back of sidewalk. 4. Note will be added for the 90% plan set. We cannot redo the 60% plan set 3 or 4 times. Hope this answers your questions... -Steve From: Vanessa Dolbee Sent: Tuesday, August 17, 2010 8:25 AM To: Steve Lee Subject: RE: Lake Washington Blvd: Planning and DSD comments Steve, The following are a few minor comments/questions about the 60% plans. - The Sidewalk detail does not include the landscape strip between the back of the curb and the sidewalk. However the width was corrected. - Landscaping was not provided on any of these plan sets, will this come later? (I know it is a new item). - The sidewalk easement line is still in a weird location, is this what was intended? - Did we need a note on the plans about plating the pervious sidewalk? Thank you for the opportunity to review the plans. 16� nessa (Dolbee CED, x7314 From: Steve Lee Sent: Monday, August 16, 2010 2:53 PM To: Arneta I Henninger; Vanessa Dolbee Subject: Lake Washington Blvd: Planning and DSD comments Attached are the 60% plans.

Great. I had that information too for the sewer. Our water utility is currently reviewing the 90% plans and will most likely revise the bend and thrust block near the sewer to get more separation between the two utilities. The water piping is a restrained joint setup and will also have an extra set of protection with the thrust blocking too. Thanks for the information. When I get the revised 90%, 1 will send you the final copy. -Steve From: Isaac, Bob[mailto:Bob.Isaac@kingcounty.gov] Sent: Thursday, May 27, 2010 10:19 AM To: Steve Lee Subject: RE: Lake WAshington Blvd Storm and Water System Improvement Project Steve, I have attached a couple of drawings for your reference.

Steve Lee From: Pat S [pat@sdg-Ilc.com] Sent: Friday, May 21, 2010 9A2 AM To: Steve Lee Cc: danmitzel@mitzel.net Subject: RE: Hawks Landing - Lake Washington Blvd Utilities Attachments: SBHC35310052107350. pdf Steve I have been discussing options with storm for the Hawks Landing Project, Please review the storm options we would like to discuss further with the City as outlined below and clouded in Blue on the attached scanned image: 1.) We would like a 12" or greater storm stub at our South Boundary we would like this stubb to be as deep as possible with gravity drainage to the outfall into May Creek 2.) We would like to re -positions the cities swale such that we can install a additional swale on parallel to Lake Washington Blvd. This will minimize the impact of the swales on developing the property as well as providing water quality treatment areas for both projects. This would require some additional piping as shown. I believe the swales can be maintained from the proposed sidewalk or potentially from the neighboring property depending on what happens with it. 3.) We would also like a storm stub roughly in the location of the proposed entrance to our site as shown on the sheet. This stub we would like as deep as possible with positive drainage to the May Creek outfall Please review and get back with Dan or I concerning these comments. Sorry this took a while to get back to you Thanks for your time Pat Severin P.E. Sound Development Group P.O.

We did not want to ask for more drainage easement area than was necessary to treat roadway runoff off LWB, nor were we asked to provide on -site hotel runoff from Dan or Spence. That would need to be agreed upon via an agreement. In order to decrease the swale depth, the width would need to be modified or another 100-feet swale would need to be built. I believe it would be easier (and cheaper) to physically change only one side of the existing swale in the future to a wider swale, but that may impact what gets built in that area for Phase 2. -Steve From: Pat S [mailto:pat@sdg-Ilc.com] Sent: Tuesday, May 11, 2010 12:40 PM To: Steve Lee; danmitzel@mitzel.net; pat@sdg-Ilc.com Subject: RE: Hawks Landing - Lake Washington Blvd Utilities Steve I would like to get a copy of the design drainage calc's for the swale and the analysis of what is being used by the swale provided. Are you indicating that we are already at the 4" design depth and there is no remaining capacity? Pat Severin P.E. Sound Development Group P.O.

The water has been modified already. Also, our preliminary work with the 60% designs already have stubs, etc. for an additional future wet bio-swale facility (if needed). Remember that for wet bioswale facilities design parameters allow only 4"maximum depth of flow in a wet bio-swale and a 100-feet minimum length with access for a vactor to reach the inlet and outlet. So you may want to ensure the future facility fits into that space longitudinally. I know the bioswale can be expanded wider to accommodate more treatment area (which depends on the future development building for phase 2 of course), but longer I have not looked into. Thank you for your comments. -Steve From: Abdoul Gafour Sent: Monday, May 10, 2010 9:34 AM To: Steve Lee Subject: RE: Hawks Landing - Lake Washington Blvd Utilities Steve, My review comments of the 60% design plans already included 12" water stubs with 3-valves cluster to both the south driveway (Sta. 20+55) and to the north driveway (Sta. 24+75) to the Hawks landing development. We are also providing another 12" stub to the south property line (Sta. 17+10), south of the proposed bioswale, in case we need a looped water main around the proposed southwest tower building. The majority of the existing on -site 12" water line must be abandoned to accommodate the new buildings and related improvements. A small section of the existing along the southeast corner of the property will remain. Abdoul Gafour Water Engineering Supervisor City of Renton Public Works 1055 S Grady Way Renton, WA 98057 425-430-7210 agafour@rentonwa.gov From: Steve Lee Sent: Monday, May 10, 2010 8:19 AM To: Ronald Straka; Abdoul Gafour Subject: FW: Hawks Landing - Lake Washington Blvd Utilties Abdoul, Attached is an email from the hotel developers' engineer. I do not see a problem with stubbing out with a 12-inch line to their site except with potential water quality water age issues if they do not use too much water? Let me know if you have any problems with us making those tees into 12"x12"x12" junctions. Thanks, Steve From: Pat S [mailto:pat@sdg-Ilc.com] Sent: Friday, May 07, 2010 11:14 AM To: Steve Lee Cc: danmitzel@mitzel.net; Pat S Subject: Hawks Landing - Lake Washington Blvd Utilties Steve I do have a couple of comments on your plans after discussing them with Dan Mitzel 1.) The proposed waterlines (2) to serve our site are 8", 1 would request that this lines be made a 12" line as this is what currently serves our site as well as giving the developer more option on site as well as raising a question. The plans appear to indicate that the existing 12" looped line through out site is going to be abandoned. Is this the case? 2.) We were discussing the options for storm and I came up with the following schematic. It show you diverting structure being moved north so we could utilize more length in a future bio filtration swale expansion to take our sight into consideration or to treat the additional flow from our development. We would have to temporarily run the swale water around the existing building which could be done with a couple of clean outs. We would also like a stub to our site so we can "plug" into this system. The flow diverter could be done so we can change the orifice to divert additional flows. I would think a 60" mahole with a dividing wall set at the top of the outlet(diverting structure) would work. I would meter flow to the swale now and in the future with a 12" (or whatever the pipe size is) plug. The drill the appropriate hole diameter with a head that given by the wall height. Let me know what you think and thanks for your consideration Pat Severin P.E. Sound Development Group P.O.

The proposal will be routed to other City departments and other jurisdictions or agencies who may have an interest in the application. The reviewers have two weeks to return their comments to the Planning Division. Within approximately two weeks, the Planning Division will prepare a report regarding the proposal's compliance with applicable codes and the City's review criteria. The application will then be presented to the City's Environmental Review Committee. The Environmental Review Committee is comprised of the Administrator of Public Works, the Administrator of Community and Economic Development, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and will then issue its decision (Environmental Threshold Determination). The Environmental Review Committee will either issue a: Determination of Non -Significance (DNS) -Make a determination the proposal will have no significant negative environmental impacts, or Mitigated Determination of Non -Significance (DNS-M)-Make a determination the proposal, if modified, would have no significant negative environmental impacts, or Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified consultant. Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is not required), a public notice of the Determination is printed in the Renton Reporter and three notices are posted at or near the site. A 14-day appeal period commences following the publication date. At the discretion of the City, a separate and additional 15-day comment period may be added prior to the 14-day appeal period. The remainder of the review process differs depending on whether a public hearing is required. Section 4-2-060 of the Renton Municipal Code stipulates whether or not a public hearing is required. Shoreline Development Not Requiring a Variance or Conditional Use Permit: A public hearing is not required. The Planning Division reviews the proposal in conjunction with the Environmental Review Committee decision and any staff or public comments prior to making a decision. The decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master Application and all parties of record. The decision will also be mailed to the State of Washington Department of Ecology. After receipt of the decision, the Department of Ecology commences a 21-day review period during which appeals can be made. Shoreline Development Requiring a Variance, Conditional Use Permit, or Environmental Review: A public hearing is required. After review of the proposal and any staff or public comments, the Planning Division staff will forward a report and recommendation and the Environmental Review Committee decision to the Hearing Examiner prior to the hearing. This report will be mailed to all persons listed on the Master Application and all parties of record. Notice of the public hearing will be published in the Renton Reporter at least 10 days prior to the hearing, the site will be posted again, and parties of record will receive notices of the hearing via mail. Applicants are strongly encouraged to attend the public hearing for their proposal. City staff will first make a presentation to the Hearing Examiner about the proposal. Then - 8 - 08l09 H:\CED\Data\Forms-Templates\Self-Help HandoutsTlanning\sm.doc the applicant and any citizens in support of the proposal will give testimony. When giving testimony, names and addresses must be stated for the record. Following this, individuals with neutral or opposing comments will give their testimony to the Hearing Examiner. City staff or the applicant will address additional questions raised throughout the hearing. The Hearing Examiner will review the proposed application concurrently with any environmental appeals and issue a final decision(s) within 14 days of the hearing unless, at the time of the public hearing, the Hearing Examiner indicates additional time will be required for issuance of the decision. The decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master Application and all parties of record. The Examiner's decision on any environmental appeals will also be mailed. The determination of the Examiner is then forwarded to the Sate Attorney General's Office and the State Department of Ecology for final approval or denial. If the Department off Ecology and/or Attorney General do not object to the Examiner's determination within 30 days, the Examiner's decision will become final. APPEAL AND RECONSIDERATION PROCESS FOR DECISIONS: Any person, including the applicant, aggrieved by the granting or denial of an application, may make a written application for reconsideration to the Reviewing Official within 14 calendar days of the date of the decision. After review of the request, the Reviewing Official may take whatever action is deemed proper. The Reviewing Official's written decision on the reconsideration request will be mailed to all parties of record within 10 days from the date the request was filed. If any party is still not satisfied after a reconsideration decision has been issued, an appeal may be submitted within 14 days to: The Hearing Examiner for Administrative decisions The State Shorelines Hearing Board concurrently with State Department of Ecology, State Attorney General's office, City of Renton Planning/Building/Public Works Department and the City Clerk for Hearing Examiner decisions. Either the Department of Ecology or the Attorney General must verify the appeal request as valid in order to the review to continue. Certification must be given within 30 days. If the request is verified, the Hearings Board conducts a review and sustains or overturns the decision of the City of Renton. Any party who fails to obtain verification or is aggrieved by the decision of the Hearings Board may appeal to the Superior Court. An appeal may be filed without first requesting reconsideration by the Reviewing Official; however, it must be filed within 14 days of the date when the original decision was issued. See Renton Municipal Code, Section 4-8-110 for further information on the appeal process and time frames. BUILDING AND CONSTRUCTION PERMIT ISSUANCE AND INSTALLATION OF IMPROVEMENTS: In the City of Renton, a Building Permit must be obtained to build buildings and structures. A Construction Permit must be obtained to install utility lines, transportation improvements and undertake work in City right-of-ways. Building and Construction Permits are separate permits. Applicants may apply for building and construction permits concurrently with their request for a land use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. - 9 - 06/09 H:\CED\Data\Forms-Templates\Self-Help Handouts\Planning\sm.doc DEFERRAL OF IMPROVEMENTS: If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings must be submitted to the Planning Division.

If approval is granted, security in the form of an irrevocable letter of credit, set -aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements. EXPIRATION AND EXTENSIONS: An approved Shoreline Substantial Development Permit and/or Shoreline Conditional Use Permit and/or Shoreline Variance shall expire, becoming null and void, two years from the effective date of the Shoreline Permit/Conditional Use/Variance unless construction activities have commenced. Where no construction activities are involved, the use or activity shall be commenced within two years of the effective date of a substantial development permit. The effective date of a substantial development permit shall be the date of the last action required on the substantial development permit and all other government permits and approvals for the development authorizing the development to proceed, including all administrative and legal actions on any permits or approvals. A greater length of time may be approved by the City at the time of permit issuance upon finding of good cause. However, actual construction of the project must be completed within five years of the effective date of the Shoreline Permit approval. The City of Renton may authorize a single extension for a period not to exceed one year based on reasonable factors, if a request for extension has been filed before the expiration date and notice of the proposed extension is given to parties of record on the substantial development permit and to the State Department of Ecology. EXPIRATION OF BUILDING PERMIT: Authorization to conduct construction activities shall terminate five years after the effective date of a substantial development permit.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply'. Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact.
