However,small lot clustering was not requested as part of the preliminary plat application,and was not reviewed and approved as part of the Hearing Examiner Decision.The purpose of this letter is to provide clarification on the use of small lot clustering, or reduced setbacks,within Mindy's Place Plat. Per RMC 4-2-110D.10.,small lot clusters of up to a maximum of fifty(50) lots shall be allowed within the R-4 zone,when at least thirty percent(30%) of the site is permanently set aside as significant open space."Such open space shall be situated to act as a visual buffer between small lot clusters and other development in the zone. The proposal meets the minimum thirty percent(30%) significant open space requirement for small lot clusters. In addition,the proposed open space acts as a visual buffer between Mindy's Place Plat and developments to the east.Therefore,the project meets the criteria for small lot cluster development. In this case,and in this instance,we will approve the partial setback reductions proposed in the attached site plan. Maximum impervious surface area, building height, maximum lot coverage, and other standards of the R-4 Zone shall continue to apply per vested code. 1055 South Grady Way,Renton,WA 98057•, rentonwa.gov Mindy's Place Preliminary Plat LUA14-000093, ECF, PP,VAR Page 2 of 2 April 25,2017 You may contact me at(425)430-7312 if you have any questions or need additional information.

The City of Renton has requested an independent peer review of the detention pond design for this project. We have received and reviewed the following documents for the project: Lg Structural calculations by Lucia Engineering titled "Mindy's Place, CIP Retaining Wall Calculations" dated.July 2, 2014. El Retaining wall plan sheet by Lucia Engineering titled "Mindy's Place, Retaining-Wall Details" dated July 2,2014. Detention pond plan sheet,Sheet 12-180, by DMP, Inc.titled "Mindy's Place, Detention Pond Details." Geotechnical engineering report,by Robinson Noble titled'"Geotechnical Engineering Report, Mindy's Place, Renton,Washington"dated April 9, 2013. This letter addresses the geotechnical aspects of the peer review. Reid Middleton, under subcontract to GeoEngineers, completed the structural aspects of the peer review, the results of which are provided in Attachment A. DETENTION POND DESCRIPTION The detention pond is planned as part of an eight-lot single-family residential development.The pond will be located along the south side of site, near residential lots 4 and 5.The ground surface is relatively level City of Renton February 11,2015 Page 2 in the area.The pond will be constructed by excavating up to about 9 feet below the ground surface. The interior of the pond will have side slopes of 3H:1V (horizontal to vertical). A 3- to 4-foot-high concrete retaining wall will be constructed around the south and east sides of the pond. The retaining wall will be located at the top of the 3H:1V interior pond side slope. Utility penetrations are not planned below the retaining wall footing. SUBSURFACE CONDITIONS The subsurface conditions at the site were characterized by Robinson Noble using two test pits excavated to depths of 7.5 to 8 feet below the ground surface. The test pits encountered approximately 6 inches of organic surface soils overlying Ito 3 feet of loose silty sand with varying amounts of gravel. Below a depth of 1.5 to 3.5 feet, the subsurface soils are interpreted to be glacial till consisting of dense to very dense silty sand with gravel. Groundwater was not encountered in the explorations. Robinson Noble indicates that perched groundwater should be expected during,wetter times of the year due to the presence of the glacial till at the site. REVIEW COMMENTS Based on our review of the documents provided,we have the following comments and opinions: 1. We are in general agreement with the subsurface characterization and geotechnical design recommendations provided by Robinson Noble for the project. 2. We concur with Robinson Noble that the native glacial till soils that will be exposed within the detention pond excavation are relatively impermeable.As such, we do not see the need for a pond liner system e.g. membrane or bentonite amended soils) provided that the soils have a maximum permeability of 1 x 10-5 centimeters per second as recommended by Robinson Noble. 3. We note that the retaining wall calculations provided by Lucia Engineering use at-rest lateral earth pressures which assumes drained conditions behind the retaining walls.A 4-inch wall drain is specified on Sheet 12-180; however, no details of the wall drain are. provided. Please provide wall drainage details, including gravel backfill gradation and fabric requirements for review. Additionally, Robinson Noble should confirm that the proposed wall drainage measures are appropriate for the assumed at-rest lateral earth pressure condition. 4. The seismic earth pressure used by Lucia Engineering for the retaining wall design is not consistent with recommendations provided on page 7 of the Robinson Noble geotechnical report.We recommend that either: (a) Robinson Noble confirm that Lucia Engineering's seismic earth pressure is acceptable or (b) Lucia Engineering redesign the retaining wall using the recommended seismic earth pressure provided by Robinson Noble. 5. The passive earth pressure used by Lucia'Engineering for the wall design does not take into account the reduced passive pressure value provided on page 8 of the Robinson Noble geotechnical report. A reduced passive pressure in front of the wall is appropriate, in our opinion, as the wall is supported on the 3H:1V pond side slopes.The retaining wall design needs to be revised for this reduced passive pressure condition,as recommended by Robinson Noble.

The applicant should recognize that the city of Renton may require the issuance of additional permits. See IBC Section 107.3.4.1. See also structural general comments below. The following is a summary: a. Concrete mix designs. - Structural V General 1.Structural special inspections. Special inspections by qualified special. inspectors,should be provided. See IBC Sections 1704,and 1705.11. The following is a summary: a. Concrete placement at concrete construction: .continuous. See also IBC Section 1705.3. b. Reinforcement at concrete construction: periodic. See also IBC Section 1705.3. 2.Structura1tests. Tests by, qualified special inspectors should be conducted. The following is a summary: a. Testing of concrete for specified compressive strength,j ', air content and slump. See IBC Sections 1705.3, 1901.2, ACI 318 Section 5.6. 1 J 3. A section on special inspection, Sheet 1 should be added by specifying special inspections (i.e., concrete placement,reinforcement). See IBC Section 1704.3.1. Refer to Sections 1704 and 1707 and the structural comment above to determine the additional types of special inspections. 4. The extent of each type of special inspection.in'the section of the structural notes on special inspection, Sheet 1, should be specified for review(e.g.,periodic or continuous). See IBC Section 1704.3.1(5). Refer to Section 1702.1 for the, definitions of continuous special inspection and periodic special inspection. Refer to Sections 1704 and 1707 and,the structural comment above to determine when continuous or periodic special inspection is required for each type of special inspection. Reid iddleton k f Mr.Shaun D.Stauffer, Principal GeoEngineers February 10,2015 File No.262015.007/00101 Page 3 - 5. The specified compressive strength,f',, is required to be the greater of the values determined for structural strength and durability. The requirements for durability are based on the exposure classes assigned to each concrete structural member and the structural engineer is required to assign the exposure classes, which are based on severity of anticipated exposure. The drawings,however, do not appear to specify these requirements. The section of the structural notes on concrete, Sheet 1, should be revised by specifyingf'c, for structural strength and the exposure classes for durability. We recommend a table listing'',and exposure classes for freezing and thawing (Fx), sulfate (Sx),permeability (Px) and corrosion(Cx)for each applicable type of concrete structural'member. See IBC Section 1901.2 and Sections 4.1.1•and 4.2.1 of ACI 318-11. See www.nrmca.org/P21?for further information. Note that ACI 318-11 defines licensed design professional," in part, as"an individual who is licensed to practice structural design...and who is in responsible charge of the structural design." 6. Based on our review of the proposed concrete Work, the'footings and walls appear to be in exposure category Fl per ACI 318-11 Table 4.2.1. By ACI 318- 11 Table 4.3.1, Fl type concrete shall have a minimum strength of 4,500 psi with a maximum water-cement ratio of 0.45 and air content per Table 4.4.1 of ACI 318-11. Please revise and resubmit Sheet I to be consistent with the 2012 IBC and ACI 318 requirements. See IBC Section 1901.2. 7.Sheet 1 references ACI 315-92 and 318-05. These references should be updated per Chapter 35 of the 2012 IBC and Sheet 1 should be resubmitted for review. It appears Sheet I should being referencing ACI 315-05 and ACI 318-11 respectively. Please verify. ' 8.Sheet 1 indicates the work shall be done in accordance with the IBC,but does not appear to specify to which version should be used. Sheet S 1 should be. revised and resubmitted indicting work shall be done in accordance with the 2012 IBC. - Foundation 9.Sheet 1 is unclear as to the extent of the 4-foot tall retaining wall. The wall, layout plan on Sheet 1 appears to indicate a 3-foot tall retaining wall for the entire length. Please indicate where this 4-foot tall occurs on Sheet 1 and resubmit for-review. See IBC Section 1604.2. Reid iddleton. Mr. Shaun D.Stauffer,Principal GeoEngineers February 10,2015 File No.262015.007/00101 Page 4 10. The active and passive earth pressures as well as the earthquake loading used in the submitted calculations do not match the values indicated on Pages 7 and 8 of the Robinson Noble report dated April 9,2013. Please provide substantiating data, such as additional cialculations using the Robinson Noble values, that indicates the proposed structure has the design capacity to resist the IBC loadings. The proposed design may need to be revised and resubmitted. Please verify. See IBC Section 1604.2. 11. The calculations are unclear as to how the proposed shear key at the bottom of the footing is to resist bending stresses. Sheet 1 does not appear to indicate reinforcing steel in the shear key. Please provide substantiating data, such as additional calculations using the Robinson Noble values,that indicates the proposed structure has the design capacity to resist.the IBC loadings. The proposed shear key design may need to be revised and resubmitted. Please verify. See IBC Section S 1604.2, 1605.1, and_1901.2. 12. Sheet 1 is unclear with respect to the required 1-foot flat soil before the slope begins. This requirement is indicated on Page 8 of the Robinson Noble report dated April 9, 2013. Plese indicate where this requirement is shown on Sheet 1 or revise and resubmit Sheet 1 indicating this requireMent. See IBC Section 1604.2.1 13. Sheet 1 should be revised to indicate the geotechnical information and special ' loadings to the proposed,concrete retaining wall. Sonic of the information that should be indicated on Sheet 1 includes the active earth pressure,passive earth pressure, the allowable bearing capacity,the seismic loading to the retaining wall, as well as the coefficient of friction between the proposed retaining wall and the soil. Please see [BC Sections 1603.1.6 and 1.603.1.8. 14. Sheet 1--is unclear as the use of wall drain behind the proposed retraining wall to avoid hydrostatic pressures from ocourring. Sheet 1 is also unclear as to the gravel backfdl and fabrie requirements indicated on Page 8 ofthe Robinson and Noble report dated April 9, 201.3. Please reVise and resubmit Sheet 1 indicating compliance with these requirements. See IBC Section 1604.2. Corrections and comments made during the review process do not relieve the permit applicant or the designers from compliance with code requirements, conditions of approval, and permit requirements; nor are the designers relieved of responsibility for a complete design in accOrdance with the laws of the state of Washington.

CITY OF REN ON AUG 2 9 4014 BEFORE THE HEARING EXAMINER FOR THE CITY RECEIVE OF RENTON CITY CLERKS• FICE Phil Olbrechts,Hearing Examiner Re: Mindy's Place . • RECONSIDERATION DECISION II Preliminary Plat LUA14-000093 A Reconsideration Decision was issued at the request of the applicant for the above- captioned matter on June 130, 2014 to clarify that a cedar fencing requirement along the southern property line;of the project was limited to the southern property line of Lot 5 with the understanding that the City's stormwater regulations would require fencing along the,border of the stormwater tract as well. An opportunity for comment from the adjoining property owner, Jerry Smith, was not provided because at the hearing it appeared that Mr. Smith and the Applicant.had agreed to limit the fencing in this manner. Subsequent to issuance of the Reconsideration Decision, Mr. Smith advised staff that he did not agree that the fencing should be limited to his shared property line with Lot 5 and the stormwater tract and that the fencing should cover the entire southern property line. Consequently, consideration of the applicant's reconsideration request was reopened through August 18, 2014 to provide Mr. Smith an opportunity to respond and the applicant an opportunity, to reply. Mr. Smith provided comments on August 6, 2014. The applicant's submitted a reply on August • 15,2014 in two separate submissions from Hans Korve and Wayne Jones. In the comments submitted on reconsideration,the applicant and Mr. Smith agree that 6 foot cedar fencing'should also be placed along the southern lot line of the storm water tract. Condition 14!will be furtherr clarified to require cedar fencing along this portion of the tract. Mr. Smith requests fencing along the southern border Of the sensitive areas tract as well. Mr. Smith bases his request for fencing along the sensitive area on the premise that people trespass onto the sensitive areas tract with motorcycles and the like. There is no.evidence in the record that this trespass has occurred. Further, it is uncontested that such a fence would encroach into wetlands and their buffers in P. 1 Reconsideration Decision I 1 violation of the City's wetland regulations. Mr. Smith notes that there is currently wire fencing along 162nd Ave. across critical areas,but as noted by the applicant this is likely due to exemptions that apply to the placement of utilities. Regardless, even if there were no legal justification for the existing fence encroachment, that does not authorize a further violation of wetland regulations for this project. For these reasons, Mr. Smith's request for additional fencing must be denied. DECISION The original decision issued for the above-captioned matter shall remain unchanged except that Condition 14 shall be replaced with the following: 14. A six foot tall cedar fence shall be installed along the southern property line of Lot 5 and the southern property line of the stormwater.tract.

City of Renton 1055 South Grady Way Renton;.WA 98057 RE: LUA-14-093 Mindy's Place- PP - Reopened Reconsideration Response Dear Ms. Timmons: In accordance with the Hearing Examiner's Reconsideration Order, dated August 5, 2014, we are responding to the comments provided by Mr. Smith, dated August 6, 2014. The Examiner is correct in asserting that the public.record clearly indicates that fencing was only proposed along the southern boundary of lot-5 and the required storm water pond, (Pg. 3, Ln. 17 & Pg. 5, Ln. 16 -Testimony). The Examiner is also correct that there is no discussion of wire fencing in the record. In his order, the Examiner.raised three questions for Mr. Smith. It appears.from•Mr. Smith's response, the questions_were not clearly addressed. We offer our opinions on the three areas of concern 1. The submitted Preliminary Plat map clearly indicates the location of the identified wetlands and their associated buffers. Any-fence construction east of the • . proposed storm water facility would encroach on the identified buffer and eventually the wetland itself. Construction Of a fence or other solid structure • across the flow path could also restrict surface water flow through the area during a storm event and cause local flooding. • 2. The-applicant is not aware of any authority-to require,a 6' wood fence across an existing wetland area which could be.in violation of the sensitive area ordinance. It is possible that through the SEPA review process a fence could serve some mitigation purpose, but no such discussion took place during the SEPA process and no such SEPA condition was adopted by the City prior to the Hearing. 3. Given that the wetland and its buffers.are existing and no development in the area is proposed, a fence east of the storm pond would appear to serve no purpose other then to bisect the wetland as it crosses onto the Smith Property. • Mindy's Place—12-180 In response to Mr. Smiths letter, it is unclear where the discussion about a 4' wood fence originates from: It is also unclear how a discussion about the 162nd frontage is relevant to the established record regarding the southern fence. The City of Renton has approved a street modification to eliminate pedestrian and landscape improvements behind the curb along the west side of 162ndAve SE. The modification approval was based on the probable impacts of the-improvements to the identified wetland and its buffer. Construction of a curb and gutter along 162nd Ave SE should limit access to the project site from the east. It should also be noted that the "Jeep"trail discussed by Mr. Smith, and identified on the existing condition map, is approximately 200' into the project site. Illegal access to'this trial would have no impact on Mr. Smith's property. Lastly, Mr:Smith discusses the existing wetland buffer fencing along the 162nd.Ave SE right-of-way. This buffer fencing was installed by the Cavala plat as part of the required sewer extension. The Renton Municipal code allows for intrusions within wetlands and their buffers for the installation and maintenance of utilities. The area in question was restored after construction and the access improvements are the minimum necessary to - maintain the.facility. This existing gravel trail would appear to have no impact on the Smith property or the issues addressed by this reconsideration order. The-Applicant is in full support of the original reconsideration approval and requests that Mr. Smith's appeal for a fence extension. beyond the east edge of the storm pond be denied. His request is inconsistent with the adopted codes and the public record. Thank y u for your time. ans A.

See Lejeune v. Clallam County, 17 64 Wn. App. 257,review denied, 119 Wn. 2d 1005 (1992)1; and 18 WHEREAS, interests of judicial economy support a reopening of the reconsideration 19 decision in this case in order to avoid a potential judicial remand to provide Mr. Smith with an arguable due process right to respond to the modifications to Condition No. 14 requested by the 20 applicant;NOW, THEREFORE, 21 1 Note that in addition to implied authority, a reasonable construction of express reconsideration authority also 22 supports the reopening of the Reconsideration Decision. RMC 4-8-100(E)(13) allows for any party of interest to request reconsideration. RMC 4-8-100(E)(13)does not bar reconsideration requests of decisions that have already 23 been subject to reconsideration. RMC 4-8-100(E)(13)also does not require a request for reconsideration to be filed in writing. Consequently, when remedying a potential due process violation, it is appropriate to construe Mr. 24 Smith's verbal request for comment on July 9,2014 as an authorized second request for reconsideration. Note also that the fairly loose reconsideration rules adopted by the City do not enable project opponents to reopen a decision at 25 any time. RMC 4-8-100(F)(e)(x)provides that the examiner's jurisdiction terminates upon expiration of the appeal period,which would have to be construed as including the authority to reconsider a decision. In this case,Mr.Smith 26 requested reconsideration within the 14 day appeal period. PRELIMINARY PLAT-2 1 ORDER 2 3 The Reconsideration Decision issued June 30, 2014 is held in abeyance in order to provide Mr. Smith an opportunity to respond to the request for reconsideration filed by the applicant on June 9, 4 2014.

In 5 his response,it would be helpful if Mr. Smith would address the following questions: 6 1. Does Mr. Smith dispute tliat fencing along the south property line east of the detention pond 7 tract would encroach into wetlands or their buffers? If so, can he identify any evidence in the record of the hearing on the preliminary plat that supports his position? 8 2. If Mr. Smith does not dispute that fencing east of the detention pond would encroach into 9 wetlands or their buffers, what legal authority does the Hearing Examiner have to order fencing into the wetlands and/or their buffers? 10 3. Why is fencing necessary, east of the detention pond tract? How would fencing mitigate impacts created by the proposed subdivision? 11 12 Mr. Smith's response must be based upon evidence admitted into the administrative record of the preliminary plat hearing (composed of the hearing testimony and hearing exhibits). No new 13 evidence will be allowed. If\Mr. Smith presents a response that may result in a requirement to fence east of the detention pond tract, the applicant will be given an opportunity to reply.

See Lejeune v. Clallam County, 17 64 Wn.App. 257,review denied,,119 Wn. 2d 1005 (1992)1; and 18 WHEREAS, interests of judicial economy support a reopening of the reconsideration 19 decision in this case in order to avoid a potential judicial remand to provide Mr. Smith with an arguable due process right to respond to the modifications to Condition No. 14 requested by the 20 applicant;NOW,THEREFORE, 21 1 Note that in addition to implied authority, a reasonable construction of express reconsideration authority also 22 supports the reopening of the Reconsideration Decision. RMC 4-8-100(E)(13) allows for any party of interest to request reconsideration. RMC 4-8-100(E)(13) does not bar reconsideration requests of decisions that have already 23 been subject to reconsideration. RMC 4-8-100(E)(13)also does not require a request for reconsideration to be filed in writing. Consequently, when remedying a potential due process violation, it is appropriate to construe Mr. 24 Smith's verbal request for comment on July 9,2014 as an authorized second request for reconsideration. Note also that the fairly loose reconsideration rules adopted by the City do not enable project opponents to reopen a decision at 25 any time. RMC 4-8-100(F)(e)(x).provides that the examiner's jurisdiction terminates upon expiration of the appeal period,which would have to be construed as including the authority to reconsider a decision. In this case,Mr.Smith 26 requested reconsideration within the 14 day appeal period. PRELIMINARY PLAT-2 r 1 ORDER 2 3 The Reconsideration Decision issued June 30, 2014 is held in abeyance in order to provide Mr. Smith an opportunity to respond to the request for reconsideration filed by the applicant on June 9, 4 2014. Mr. Smith's response must be received by Rocale Timmons no later than 5:00 pm,August 13, 2014. The response may be delivered to Ms. Timmons or emailed at rtimmons@a,rentonwa.gov. In 5 his response, it would be helpful if Mr. Smith would address the following questions: 6 1. Does Mr. Smith dispute that fencing along the south property line east of the detention pond 7 tract would encroach into wetlands or their buffers? If so, can he identify any evidence in the record of the hearing on the preliminary plat that supports his position? 8 2. If Mr. Smith does not dispute that fencing east of the detention pond would encroach into 9 wetlands or their buffers; what legal authority does the Hearing Examiner have to order fencing into the wetlands and/or their buffers? 10 3. Why is fencing necessary east of the detention pond tract? How would fencing mitigate impacts created by the proposed subdivision? 11 12 Mr. Smith's response must be based upon evidence admitted into the administrative record of the preliminary plat hearing (composed of the hearing testimony and hearing exhibits). No new 13 evidence will be allowed. If Mr. Smith presents a response that may result in a requirement to fence east of the detention pond tract, the applicant will be given an opportunity to reply. Once the request 14 to reconsider Condition No. 14 has been resolved, a new fmal decision will issue along with a new 14 day appeal period. 15 16 DATED this 5th day August,2014. 17 etf' 18 T iiiT A.tIhreea mm 19 City of Renton Hearing Examiner 20 21 22 23 24 25 26 PRELIMINARY PLAT-.3 tfflm From: Bonnie Walton Sent: Friday, July 1,8,.2914 1:06 PM To: Phil Olbrechts (olbrechtslaw@gmail.com); Rocale Timmons;Jennifer T. Henning Subject:Mindy's Place- LUA-14-000093- RENTON Mr. Smith was in today asking for clarification on the Hearing Examiner Reconsideration Decision dated 6/30/2014: In the 5/28/14 Preliminary Plat decision, page 2, line 14, Mr. Korve expressed willingness to place a fence all the way around the property,AND on page 20, item 14, line 11, approval was conditioned on installation of a 6'Cedar fence along the sourthern boundary line. In the reconsideration, item 14 was revised to indicate a 6' cedar fence shall be installed along the southern property line of Lot 5. Does that mean that Lot 5 will be fenced in addition to the rest of the plat property being fenced; or does it mean that only the southern property line of Lot 5 will be fenced and nothing else? The citizen is just not sure how to interpret this and would like to determine where all of the fencing will be required and installed. Your help and clarification will be appreciated. Thank you.

I asked for a fence along my property to protect it from the new houses. Previous releases from you called for a 6 foot cedar fence along my property. On May 29 th release plat 3 line 13 and 14 says they will put in a 6 foot fence. Line 17 says this would mean fencing lot 5 also. During the meeting on May 29 Lake ridge development said that it didn't include lot 5. It was agreed that it would. So when you released info dated July 1 it should of said including lot 5 not fencing only on lot 5. You need to correct this since it was already agreed to.

Condition 14, Page 20 has to do with fencing the south property line. I believe the intent was to fence across the south property line adjacent to Lot 5 and the detention pond.

There is a category two wetland on the site as well as a class four stream. Topographically, the site is flat, although there is a slope with 14ft relief. The site is rectangular 21 in shape, is vacant, and is surrounded by single-family residences that are zoned R4.Recent approvals on nearby sites include two preliminary plats. She submitted Exhibits 1-17 to the record. The applicant 22 requests preliminary plat review as well as a street modification for the subdivision of the site into eight single-family lots and two tracks. The application was accepted for review in June,2013, but the project 23 was placed on hold pending receipt of supplemental materials; the project has been taken off hold, and a 24 new comment period began on March 6, 2014. Staff received three comment letters. Most questions in the letters were concerned with pedestrian access along 162nd Ave SE and drainage concerns within the 25 vicinity of the project. On March 24, 2014, the Environmental Review Committee for the city issued a determination of non-significance mitigated. That included two mitigation measures primarily related to 26 drainage improvements on site. The applicant is required to place on the face of the preliminary plat a PRELIMINARY PLAT- 1 1 limit on the impervious surface for each less if it is less than allowed by code.Additionally,the applicant is required to submit a secondary review during final engineering design that includes hydro-geotechnical 2 evaluations for the detention pond"that is proposed on the site. 3 Ms. Timmons stated that the preliminary plat proposes eight single-family lots with two tracks; one track 4 is for critical areas, the other is I for the drainage detention pond. The net density that the applicant proposes is approx. two and a half dwelling units per acre. The average lot sizes range from 7200sqft to 5 7700sqft. Access is proposed via 160th Ave SE, and internal access is proposed via a new road that is 6 Road A depicted in the plan. This road terminates in a hammerhead turn around. Ms. Timmons stated that Staff believes the proposal complies with the City's comprehensive plan,7 objectives, andpolicies if all conditions of approval are met. Specifically, staff looked at policyT9,j pp 8 which stipulates that pedestrian pathways in residential neighborhoods be arranged as an interconnected network, and staff recommends that'a connection from the developed lots through the site to a current 9 pedestrian corridor needs to be built as a condition of approval.Also,the proposal complies with most of the development standards of the R4 zoning classification; if all the recommended conditions of approval 10 are complied with, the proposal will meet all of the development standards. Ms. Timmons stated that an 11 administrative interpretation, CI45, which is Exhibit 17, eliminated a footnote that allowed for reductions in lot sizes and dimensions for the R4 zone, which is RMC4-2-110D11. That elimination 12 became effective on January 23,2014, but, since the application was submitted originally in June,2013, Staff believes this application should be able to utilize the footnote. The Staff Report mentions a lot 13 width standard of 70ft, but it is actually 60ft in this case since this(proposal is able to utilize the footnote. Also, the conceptual landscape plan does not comply with the 10ft, on-site landscape requirement, thus 14 Staff has recommended as a condition of approval a revised landscape plan. 15 Ms. Timmons stated that the proposal complies with most of the•critical area regulations if all the 16 recommended conditions of approval are met. There is a category two wetland as well as a class four stream on the site. The applicant does not currently propose any impacts to the site, but there is a tight- - 17 line from the detention pond that would cross through the critical,areas, and Staff has recommended a pedestrian pathway that would cross through the critical areas.For this reason, Staff recommends that the 18 applicant submit a revised mitigation plan, and regulations allow for a soft surface trail in critical areas without a variance when there is a mitigation plan. Also, the proposal complies with community asset 19 regulations, and it complies with the review criteria for subdivisions if all the recommended conditions of 20 approval are met. Specifically, RMC4-7-150E2, which Staff has already mentioned, requires that linkages, including pedestrian paths, be provided in neighborhoods when they are able to create 21 interconnected networks,thus Staff has recommended as a condition of approval that a pedestrian path be built. Further, Ms. Timmons stated that the requested street modification in the proposal meets the 22 objectives and the safety of the code requirements if the required pedestrian path is built. ' ' 23 Ms. Timmons stated that in their analysis Staff looked at`the availability of public services, and the 24 parks,police, fire prevention, and school district staff have indicated that there are sufficient resources to furnish services to the proposed development. To address the requirements for safe walking conditions 25 for students per RCW58-1.7-110-2,-Staff recommends that the applicant demonstrate a safe walking condition for students from the subject site to the nearby bus stop. Also, the applicant is required to 26 submit a certificate,of water availability from water district 90, In regards to sewage, the applicant is PRELIMINARY PLAT 2 C 1 providing gravity service for lots 1,2, 3, and 6, but lots 4, 5, 7, and 8 will require pumps for sewer. Ms. Timmons stated that the applicant submitted a preliminary drainage plan report. The applicant plans to 2 surround the detention pond with a fence,thus it is not necessary to have a 15ft vegetation buffer around 3 the pond,and Staff supports a reduction in the recommend landscape buffer for the detention pond. In summary,Ms.Timmons stated that Staff recommends approval for the Mindy's Place preliminary plat 4 subject to seven recommended conditions of approval. She noted that fencing along the detention pond is proposed on the side where the peighbors with concerns are located. Ms. Timmons said there was a 5 pedestrian corridor on 162nd Ave, and it was paved to the north of the site. There is not a pedestrian corridor on 160th Ave,but it is paved. 6 7 Applicant Testimony 8 Mr. Wayne Jones,Lakeridge Development,the applicant, stated that the stream on the site only runs with water when there is a,large rain event. He stated that his concern with building a trail for pedestrians on 9 the site was the impact that it would have on the critical areas, which to mitigate would extend the duration of the project a great deal. Mr.Jones stated that they will replace a roughly 250ft water main on 10 160th Ave,which would provide water for the site as well as for some houses to the west. 11 Mr. Hans Korve, Lakeridge Development, stated that the code says the 15ft vegetation buffer on a 12 retention pond can be reduced or eliminated. They considered what it would look like to have•'a 1511 vegetation buffer in addition to the planned 6ft cedar fence, and they found it would pose maintenance 13 issues without serving a purpose as far as obscuring the pond from view,thus they proposed to staff that they eliminate the buffer. They will put in a 6ft cedar fence, however. Mr. Korve submitted documents 14 titled Preliminary Plat Mindy's Place Lot'Width/Setbacks to the record, and they were admitted as Exhibit 18. 15 16 Public Testimony S 17 Mr. Jerry Smith stated that he owns the property directly south of the site, and he wants a fence that separates the project from his property;this would mean fencing along lot 5 in the project.He stated that 18 he has nothing against the development, and he does not have a problem with it. His problem is with the storm water, and he wrote letters that expressed that concern. Primarily, he is concerned that they will 19 dump the water from the pond into what they call a class four stream,which means essentially that they 20 will dump water onto his property via the ditch on 160th Ave. He stated that multiple ponds on 160th Ave dump water onto his property already, and now this proposal plans to dump water onto his property 21' too according to page 3 in the Staff Report. Mr. Smith stated that he did not see why they could not run the water out to 162nd Ave where there is a pond rather than onto 160th Ave where it ends up on his 22 property.He pays taxes for his property,but he cannot sell it; developers tell him there is too much water running onto it. Mr. Smith submitted to the record two photographs'of the flood on his property to the 23 record, and they were admitted to the record as Exhibit 19. 24 Staff Rebuttal 25 Ms.,Timmons submitted to the record a King County drainage investigation report from March, 2006, 26 and it was admitted to the record as Exhibit- 20. Ms. Timmons stated that class four streams are PRELIMINARY PLAT-3 1- intermittent streams,which means they do not necessarily have to have water in them throughout the year to be classified as a stream. Exhibit 5 classifies the stream on site as a class four stream. Ms. Timmons 2 stated that,to clarify for the record,Mr. Smith's letter is Exhibit 11. 3 Mr. Steve Lee, Development Engineering Manager, stated that the submitted information for a 4 preliminary plat complies with RMC4-6-030,which is the drainage manual for the city.The drainage for the site flows to the pond before it is discharged towards 162nd Ave. This project proposes walls within 5 the drainage pond, and a secondary review will be conducted for that since it will play into the overall design of the pond. Mr. Lee stated that the pond_is designed to mimic the forested conditions at the site 6 before development, thus the flow rate on the site will not increase with development. The Hearing Examiner asked there could not be an increase in the overflow from the pond due to the impervious surfaces that would come with development. The change between the two conditions is the attenuation. 8 Attenuation is the rate at which it;perks into the ground. The pond does store the volume of release from the site. There is no infiltration at this point. After this development is finished, the amount of water 9 flowing across the property will be the same. The one change will be the rate at which the water enters the wetlands. This requires a review. In regard to 160th Ave,the water flows north to south, enters into 10 a ditch, and eventually reaches Mr. Smith's property. It is an existing conditions problem, and, the 11 topography causes the water to flow into Mr. Smith's property. It is a potential Public Works issue. This condition will not be exacerbated by the new development.\ The frontage improvements to 160th 12 will result in the water maintaining its present course. As part of the requirements for the pond, for any volume increase from areas the applicant cannot detain into the pond, the pond will be upsized to 13 accommodate the runoff that would normally occur. Some of the runoff from the 160th Ave improvements will go into the pond. The street and subdivision improvements will not cause an increase 14 in water. 15 Under questioning by Mr. Smith, Mr. Lee stated that water will run continuously longer, but at a 16 controlled rate of discharge. The new drainage manual attempts'to mimic discharges for peaks and volumes which is termed a durational analysis. Ponds are larger and orifices are smaller under the new 17 guidelines. 18 Under questioning by the Hearing Examiner, Mr. Lee testified that, on the forested area at the western portion of the property, the water that is infiltrated will ultimately go to the wetland on the eastern 19 portion. The water goes through the soils and acts as inter`flow, but eventually reaches the eastern 20 wetland. The other developments such as Liberty Garden also discharge to the wetland at its existing conditions prior to development. 21 Ms. Timmons noted that the previous new developments are on the other side of 160th SE. As part of 22 those developments, drainage improvements were required. These improvements are on the western side of the un-improved 162nd Ave SE. Page 10 of Exhibit 8 notes these downstream improvements which 23 have been completed specifically at the circle point on 144th and 162nd Ave SE. Both those preliminary 24 plats (Cavalla and Liberty Gardens) comply with King County Surface Water Manuals. Staff cannot comment on-all of the new developments because this area was recently annexed from King County. 25 Under questioning by the Hearing Examiner, Mr. Lee postulated that the reason stormwater has increased on Mr. Smith's property could be changes in groundwater conditions. He does not believe it is 26 PRELIMINARY PLAT-4 1 the new developments causing the problems because these developments are on the east side of 162nd Ave SE. 2 3 Ms. Timmons stated that the City recommends broadening the scope of the independent secondary review of the off-site drainage if the applicant would be willing to do so. Additionally, in regard to the 4 critical area and pedestrian crossing, staff had previously stated a variance would not be necessary, but, upon further review, the applicant will need to submit a variance request. Staff would be supportive of 5 such a variance upon Hearing Examiner approval. 6 Vanessa Dolbee, planner, stated that there is.a new exception in the code that allows new trails through 7 wetland provided the trail is in compliance with trail construction under.the SMP regulations. Staff would not object to requiring Army Corps approval for the trail. 8 Applicant Rebuttal 9 Mr. Jones testified that the water, from 160th is the biggest problem with this application. From the 10 160th side, all of the water will be 'directed into the drainage pond. The outfall for the pond is the 11 wetland area. The wetlands areaiin the SE extends onto Mr. Smith's property, but this area,has been a wetlands for a long period. The project does not add water to 160th. 12 Mr. Korve stated that the water from the wetlands did affect the Liberty Gardens project. The water 13 crosses 162nd Ave and travels onto the Liberty Gardens property. None of the water from Liberty Gardens could flow to Mr. Smith's property. The water should freely move beyond Mr. Smith's 14 property. In regard to Mr. Smith's request for a fence and buffer, the applicant is happy to construct a cedar fence all the way around the property. He provided an elevation drawing depicting a fence 15 (Exhibit 21). However, with the landscaping requirement beyond the chain-link fence,this creates a No 16 Man's Land between the two fences,and a difficult situation in regard to maintenance. The applicant believes the landscaping is repetitive. The cedar fencing would extend along the length of lot 5. 17 Public Testimony 18 Mr. Smith noted that he has no problem with no landscaping betweenl the two fences. He reiterated his 19 concerns that the water will go from the detention pond and onto his property. 20 EXHIBITS 21 22 Exhibits 1-17 listed on page 2 of the May 13, 2014 Staff Report, in addition to the Staff Report itself 23 (Ex.'1),were admitted into evidence during the public hearing. Additional exhibits admitted during the hearing are the following: 24 Exhibit 18 Preliminary Plat Mindy's Place Lot Width/Setbacks 25 Exhibit 1.9 photographs of the flooding on Mr. Smith's property 26 PRELIMINARY PLAT-5 ' C 1 1 Exhibit 20 King County drainage investigation report from 2006 2 Exhibit 21 depiction of site with cedar fence 3 J 4 FINDINGS OF FACT 5 Procedural: 6 7 1. Applicant. See Exhibit 7—List of Owners. 8 2. Hearing. The Examiner held a hearing on the subject application on May 13,2014 in the City of Renton Council City Chambers. 9 10 3. , Project Description. The applicant is requesting preliminary plat approval for the subdivision of the 4.14 acre parcel into 8 lots for the future construction of single family residences and two tracts for 11 critical areas and drainage. The site is currently vacant. " The project site is located within the Residential - 4 (R-4) dwelling units per acre zoning classification. The proposed lots would have a lot 12 size ranging from 7,200 square feet to 7,733 square feet. Access to all lots would be provided via 13 private driveways from a new proposed public road (Road 'A') extended from 160th Ave SE which terminates in a hammerhead turn-around. The applicant is requesting a street modification,from RMC • 14 4-4-060, in order reduce the width of the hammerhead turnaround to 20 feet and eliminate frontage 15 improvements along 162nd Ave SE. The site contains a Category 2 wetland and Class 4 stream. 16 4. Adequacy of Infrastructure/Public Services. The project will be served by adequate 17 ' infrastructure and public services as follows: 18 A. Water and Sewer Service. This site is located in the Water District 90 water service 19 boundary. Sewer service will be provided by the City of Renton. A water availability certificate is required from Water District 90. There are existing sewer mains on both 160th 20 Ave SE and 162nd Ave SE. 21 B. Police and Fire Protection. Police and Fire Prevention staff indicate that sufficient resources 22 exist to furnish services to the proposed development; subject to the provision of Code 23 required improvements and fees. A fire impact fee, based on new single family lots, will be required in order to mitigate the proposal's potential impacts to City emergency services. 24 The fee is payable to the City as specified by the Renton Municipal Code. Currently the fee 25 is assessed at$488.00 per single family residence. 26 PRELIMINARY PLAT-6 f 1 C. Drainage. The proposal provides for adequate stormwater drainage facilities. The site is located within the Lower Cedar River Basin of,the Cedar River. The site slopes to east to a 2 low point near the center of the property where it generally drains to the south/southeast. 3 The site received surface water runoff from approximately 10 acres of off-site property to the 4 north. Stormwater enters the site via sheet flow along the northern property, line and presently discharges as an intermittent Class 4 stream near the southeast of the property. 5 The stream then travel's across the 162nd Ave SE right-of-way onto the Liberty Gardens plat LUA08-093). The water then continues to flow south and then enters back into the 162nd6 Ave SE right-of-way where it is collected in an 18-inch pipe. The pipe is conveyed under the 7 newly constructed sewer access road in 162nd Ave SE and then empties into a stormwater pond at the intersection of 162nd Ave SE and SE 144th St. 8 9 The applicant submitted a Preliminary Drainage Report prepared by Daley-Morrow-Poblete, Inc., dated I March 25, 2013 (Exhibit 8). The report states that the runoff from the proposed 10 project would be collected and conveyed by a catch basin/pipe network to a detention pond 11 on the southern edge of the developed area. The proposed facility would then discharge into the onsite stream. The storm pond is designed per the 2009 King County Surface Water 12 Design Manual as amended by the City of Renton. 13 The report states that the project should not pose significant negative impacts to the 14 downstream drainage course and all core and six special requirements are contained in the 15 report. However, staff received comments, from surrounding property owners,with respect to drainage concerns for the proposal and the surrounding areas (Exhibits 9,-10, 11). There 16 have also been identified existing drainage problems in the area and the potential for the 17 proposal to aggravate existing or create new drainage problems. The applicant is proposing to include a pond wall!of approximately 4-feet in height with flow control staging against the 18 wall. However, due to potential seepage in and out of the pond, additional secondary review 19 is required per the Determination of Non-Significance- Mitigated (DNS-M) during final engineering design that includes hydro-geotechnical evaluations for buoyancy and lining, 20 structural review and wall drainage relief against potential hydrostatic pressures (Exhibit 21 13). The secondary review will be required to be conducted by an independent reviewer selected by the City at the applicant's expense and shall be approved by the City's Plan 22 Reviewer prior to engineering plan approval. Additionally,the applicant would be required • 23 to be provide due diligence in the grading and collection of drainage design during the construction phase so that runoff and erosion does not impact the neighboring properties. 24 25 The applicant should take note that the drainage report states that the permeability of the site soils will not meet the standards for infiltration and as a result the drainage report 26 recommends limiting the impervious surface to 49.5% of the site in order to receive the PRELIMINARY PLAT-7. 1 1 Reduced Impervious Surface Credit. Therefore the Determination of Significance — 2 Mitigated (DNS-M) included a mitigation measure requiring the applicant to record on the face of the Preliminary Plat the maximum amount of square footage of impervious surface 3 allowed for each new lot if less than allowed by code if the applicant intends to utilize the 4 Reduced Impervious Surface Credit(Exhibit 13). 5 Finally, an existing administrative interpretation requires all drainage facilities be required 6 to maintain up to a 15-foot vegetated buffer around drainage pond facilities (Exhibit 12). Therefore, staff recommends as a condition of approval the applicant be required to submit a 7 revised landscape plan, depicting up to a 15-foot landscape buffer around the proposed drainage facility. The revised landscape plan shall be'submitted to, and approved by, the 8 Current Planning Project Manager prior to construction permit approval. 9 Some compelling testimony was provided by Gerald Smith on concerns that the proposal 10 will drain onto his property. 'Mr. Smith submitted several photographs, Ex. 19, showing 11 extensive flooding on his property. Mr. Smith testified that this flooding has been exacerbated since the approval of the Liberty Gardens and Cavella developments. However, 12 Mr. Lee, an engineer from the Public Works Department, testified that the proposal will not 13 increase any stormwater runoff from the project site. Currently, all stormwater at the site runs or infiltrates to the on-site pond. The stormwater system,required of the applicant will 14 continue to direct all stormwater to the wetland. Waters will be retained in a detention pond 15 that is designed to release water at the same rate as pre-development (actually forested) conditions. The staff ireport and applicant testimony also establish that stormwater flows 16 from Liberty Gardens and Cavella don't cross the Smith property, but rather flow to the east 17 and south of his property to a stormwater pond at the intersection of 162nd Ave SE and SE 144th St. For these reasons, it is determined that the proposal will not add to the flooding 18 problem on the Smith property. 19 D. -Parks/Open Space. City ordinances require the payment of park impact fees prior to 20 building permit issuance. RMC 4-2-115, which governs open space requirements for 21 residential development, does not have any specific requirements for open space.for residential development in the R-4 district. The impact fees provide for adequate parks and 22 open space. 23 E. Streets. The proposal provides for adequate streets. Access to the plat is proposed via 24 160th Ave SE via a new curb cut,proposed to be improved as part of the plat improvements. 25 Internal access is proposed via a new limited residential access road (Road A) which terminates in a hammerhead turnaround. The City's public works staff has reviewed the 26 proposed street improvements and traffic impacts and found that with staff recommended PRELIMINARY PLAT-8 1 conditions of approval that the proposal provides for adequate streets and is consistent with 2 all City requirements, excluding the street modification approved by this decision. There is no evidence to the contrary. 3 4 F. Parking. Sufficient area exists, on each lot,to accommodate required off street parking for a minimum of two vehicles per dwelling unit as required by City code. 5 G. Schools. It is anticipated that the Issaquah School District can accommodate any additional 6 students generated by this proposal at the following schools: Briarwood Elementary (1.51 7 miles from the subject site), Maywood Middle,School (0.75 miles from the subject site) and Liberty High School(1.49 miles from the subject site). RCW 58.17.110(2)provides that no 8 subdivision be approved without making a written finding of adequate provision made for 9 safe walking conditions for students who walk to and from school. While the designated schools are located within a close proximity of the subject site future students are designated 10 to be transported to school via bus. The bus stop for all three schools would be located at 11 160th Ave SE at SE 137th Place(Exhibit 15). It appears there are not designated walkways for portions of 160th Ave SE between the subject site and the designated bus stop. 12 Therefore, staff recommends as a condition of approval the applicant be required to 13 demonstrate safe walking conditions for students from the subject plat to the designated bus stop at 160th Ave SE at SE 137th Place prior to construction permit approval. This may 14 include a dedicated shoulder, curb, or some other alternative as determined by the Current 15 Planning Division. 16 Additionally, staff has recommended the applicant be required to provide a pedestrian 17 connection across the critical area to connect the development to the existing pedestrian corridor in 162nd Ave SE as a means of pedestrian connectivity between neighborhoods(see 18 discussion above under Compliance with Subdivision Regulations). This pedestrian 19. connection would also potentially serve to further comply with the safe routes to school program by providing walking alternatives to schools within the vicinity of the subject site. 20 21 A School Impact Fee, based on new single family lots, will also be required in order to mitigate the proposal's potential impacts to Issaquah School District. The fee is payable to 22 the City as specified by the Renton Municipal Code. Currently the fee is assessed at 23 5,730.00 per single family residence. 24 5. Adverse Impacts. There are no adverse impacts associated with the proposal. Adequate public facilities and drainage 'control are provided as determined in Finding of Fact No. 4. The proposal 25 involves single-family housing at a density that is only 2.5 dwelling units per acre, which is a lower 26 density than that allowed for surrounding development. The applicant also proposes to place a cedar fence along the western side of the property. Consequently, there are no issues of compatibility with PRELIMINARY PLAT-9 1 1 surrounding development. Tree retention will also help maintain compatibility. The proposal is designed to comply with the City's tree retention requirements. The eastern portion of the site is covered 2 with dense trees and shrubs. The west is more sparsely vegetated and includes a cleared area where a 3 home once stood. There are a total of 354 trees located on site of which 45 trees are proposed to be retained outside of the critical area and its buffer (Exhibit 3). The applicant is required to retain 30 4 percent of the trees located on site that are not located within critical areas,proposed rights-of-way and access easements. Of the 354 trees located on site 207 trees would be excluded from the tree retention , 5 requirements. Therefore, the applicant would be required to retain at least 41 trees on site. The applicant has proposed to retain 45 trees outside of the critical areas and their buffers and therefore 6 complies with the code(Exhibit 3). 7 Other than public infrastructure,and compatibility, the only remaining adverse impact potentially 8 associated with the project is critical areas. The proposal will not adversely affect any critical areas. The applicant submitted a Critical Areas Report, prepared by Sewell Wetland Consulting, Inc. (dated 9 February 18, 2013), identifying a portion of a Category 2 wetland located on the subject site (Exhibit 5). Additionally, a Class 4 stream enters the wetland from the north..The stream and wetland are the 10 only critical areas located at the project site. The stream passes in a culvert through approximately half of the site flowing south and exits the site at the southeast. Category 2 wetlands are required to have a1150-foot buffer measured from the+wetland edge. The Class 4 stream is required to maintain a 35-foot 12 buffer which is fully encompassedjby the wetland buffer. The report states there are no impacts to the critical areas proposed on site. 13 No portion of the proposal will encroach into the stream or -wetland buffers except for drainage 14 discharge from the project's storwater system and a pedestrian trail connection recommended by staff. Trails are permitted in the outer edge of the buffer pursuant to RMC4-3-050M. Critical area impacts 15 are likely as part of proposed tight lining of the drainage on site and to provide recommended pedestrian 16 connectivity to the 162nd Ave SE corridor. The applicant will be required to comply with RMC 4-3- 050 Critical Areas regulations to mitigate for any impacts permitted to the wetland buffer. As a 17 condition of approval, the applicant shall submit a final mitigation plan for impacts (tight-lining of drainage system and pedestrian connections) to the critical areas on site or their buffers. The final 18 mitigation plan shall be submitted to and approved by the Current Planning Project Manager prior to utility construction permit approval. 19 20 21 Conclusions of Law 22 23 1. Authority. RMC 4-7-020(C)and 4-7-050(D)(5)provide that the Hearing Examiner shall hold a hearing and issue a final decision on preliminary plat applications. 24 2. Zoning/Comprehensive Plan Designations. The subject property is zoned Residential 4 dwelling 25 units per net acre(R-4). The comprehensive plan map land use designation is Residential Low Density 26 (RLD). ; PRELIMINARY PLAT- 10 1 3. Review Criteria. Chapter 4-7 RMC governs the criteria for subdivision review. Applicable 2 standards are quoted below in italics and applied through corresponding conclusions of law. RMC 4-7-080 B : A subdivision shall be consistent with the followingprinciples ofacceptability:3 p P p tJ': 4 1. Legal Lots: Create legal building sites which comply with all provisions of the City Zoning Code. 5 2.Access:Establish access to a public roadfor each segregated parcel. 6 3. Physical Characteristics: Have suitable physical characteristics. A proposed plat may be denied 7 because offlood, inundation, or wetland conditions. Construction of protective improvements may be required as a condition of approval, and such improvements shall be noted on the final plat. 8 4. Drainage: Make adequate provision for drainage ways, streets, alleys, other public ways, water 9 supplies and sanitary wastes. 10 4. As to compliance with the,Zoning Code,Finding 19(2)of the staff report is adopted by reference 11 as if set forth in full, except for any conclusions implied or express that staff may amend the Zoning Code by administrative interpretation. As depicted in the plat map,Ex.2, each proposed lot will directly 12 access a public Road,Road A. As determined in Finding of Fact No. 4 and 5, the project is adequately 13 designed to prevent any impacts to critical areas and will not cause flooding problems. As determined in Finding of Fact No.4,the proposal provides for adequate public facilities. 14 5. RMC 4-7-080(I)(1): ...The Hearing Examiner shall assure conformance with the general 15 purposes of the Comprehensive Plan and adopted standards... 16 6. The proposed preliminary play is consistent with the Renton Comprehensive Plan as outlined in 17 Finding 19(2)of the staff report,which is incorporated by this reference as if set forth in full. 18 RMC 4-7-120(A): No plan for the replotting, subdivision, or dedication of any areas shall be 19 approved by the Hearing Examiner unless the streets shown therein are connected by surfaced road or street(according to City specifications) to an existing street or highway. 20 7. Road A will connect to 160th Ave SE 21 RMC 4-7-120(B): The location of all streets shall conform to any adopted plans for streets in'the 22 City. 23 8. The City's adopted street plans are not addressed in the staff report or anywhere else in the 24 administrative record. However, the only other street connection possible for the proposal would be to 162 Ave SE, which would require the construction of a road through a Category 2 wetland and/or its 25 buffer. The criterion quoted above must be construed as met since the proposal conforms to the City's 26 street plan to the extent possible Without violating the City's critical area standards. PRELIMINARY PLAT- 11 1 RMC 4-7-120(C): If a subdivision is located in the area of an officially designed[sic]trail, 2 provisions shall be made for reservation of the right-of-way or for easements to the City for trail purposes. 3 9. The only trail in the area that could potentially qualify as a"designated"trail is on the adjoining 4 Cavalla plat. The conditions of approval require a trail linkage to this trail. The criterion is met. 5 RMC 4-7-130(C): A plat, short plat, subdivision or dedication shall be prepared in conformance 6 with the following provisions: 7 1. Land Unsuitable for Subdivision: Land which is found to be unsuitable for subdivision includes 8J land with features likely to be harmful to the safety and general health of the future residents (such as lands adversely affected by flooding, steep slopes, or rock formations). Land which the 9 Department or the Hearing Examiner considers inappropriate for subdivision shall not be 10 subdivided unless adequate safeguards are provided against these adverse conditions. • 11 a. Flooding/Inundation:Ifany portion of the land within the boundary of a preliminary plat is subject to flooding or inundation, that portion of the subdivision must have the approval of the State 12 according to chapter 86.16 RCW before the Department and the Hearing Examiner shall consider 13 such subdivision. 14 b. Steep,Slopes:A plat, short plat, subdivision or dedication which would result in the creation of a lot or lots that primarily have slopes forty percent(40%) or greater as measured per RMC 4-3- 15 050J1a, without adequate area at lesser slopes upon which development may occur, shall not be 16 approved. 17 18 3. Land Clearing and Tree Retention:Shall comply with RMC 4-4-130, Tree Retention and Land 19 Clearing Regulations. 20 4. Streams: 21 a. Preservation:Every reasonable effort shall be made to preserve existing streams, bodies of water, and wetland areas. 22 23 b. Method:If a stream passes through any of the subject property, a plan shall be presented which indicates how the stream will be preserved The methodologies used should include an overflow 24 area, and an attempt to minimize the disturbance of the natural channel and stream bed. 25 c. Culverting: The piping or tunneling of water shall be discouraged and allowed only when going 26 under streets. PRELIMINARY PLAT- 12 1 d. Clean Water:Every effort shall be made to keep all streams and bodies of water clear of debris 2 and pollutants. 3 10. The land is suitable for a subdivision as the stormwater design assures that it will not contribute to flooding and development will not encroach into critical areas except as authorized by the City's 4 critical area regulations. No piping or tunneling of streams is proposed. Trees will be retained as ' 5 required by RMC 4-4-130 as determined in Finding of Fact No. 5. The on-site stream will be protected by the critical area buffer that applies to it. The City's stormwater regulations provide for adequate 6 protection of water quality for the on-site stream and wetlands. 7 RMC 4-7-140: Approval of all subdivisions located in either single family residential or multi- 8 family residential zones as defined in the,Zoning Code shall be contingent upon the subdivider's dedication of land or providing fees in lieu of dedication to the City, all as necessary to mitigate the 9 adverse effects of development upon the existing park and recreation service levels. The 10 requirements and procedures for this mitigation shall be per the City of Renton Parks Mitigation Resolution. 11 11. City ordinances require the payment of park impact fees prior to building permit issuance. 12 13 RMC 4-7-150(A): The proposed street system shall extend and create connections between existing streets unless otherwise approved by the Public Works Department. Prior to approving a street 14 system that does not extend or connect, the Reviewing Official shall find that such exception shall 15 meet the requirements of subsection E3 of this Section. The roadway classifications shall be as defined and designated by the Department. 16 12. The internal road,Road A, does not connect to 162 Ave. This is justified in subsection E3 in 17 order to avoid encroachment into the wetlands and stream of the site. 18 RMC 4-7-150(B): All proposed street names shall be approved by the City. 19 13. As conditioned. 20 RMC 4-7-150(C): Streets intersecting with existing or proposed public highways, major or 21 secondary arterials shall be held to a minimum. 22 14. There is no intersection with a public highway or major or secondary arterial. 23 RMC 4-7-150(D): The alignment of all streets shall be reviewed and approved by the Public Works 24 Department. The street standards set by RMC 4-6-060 shall apply unless otherwise approved. Street alignment offsets of less than one,hundred twenty five feet(125) are not desirable, but may be 25 approved by the Department upon a showing of need but only after provision of all necessary safety 26 measures. PRELIMINARY PLAT- 13 r J r J 1 15. As determined in Finding of Fact 4, the Public Works Department has reviewed and approved 2 the adequacy of streets,which includes compliance with applicable street standards. . 3 RMC 4-7-150(E): 4 1. Grid:A grid street pattern shall be used to connect existing and new development and shall be the predominant street pattern in any subdivision permitted by this Section. 5 2. Linkages:Linkages, including streets, sidewalks,pedestrian or bike paths, shall be provided 6 within and between neighborhoods when they can create a continuous and interconnected network of roads and pathways. Implementation of this requirement shall comply with Comprehensive Plan Transportation Element Objective T-A and Policies T-9 through T-16 and Community Design 8 Element, Objective CD-hand Policies CD-50 and CD-60. 9 3. Exceptions: 10 a. The grid pattern may be adjusted to a `flexible grid"by reducing the number oflinkages or the 11 alignment between roads, where the following factors are present on site: 12 i. Infeasible due to topographical/environmental constraints; and/or 13 ii. Substantial improvements are existing. 14 4. Connections:Prior to adoption of a complete grid street plan, reasonable connections that link 15 existing portions of the grid system shall be made.At a minimum, stub streets shall be required within subdivisions to allow future connectivity. 16 5.Alley Access:Alley access is the preferred street pattern except for properties in the Residential 17 Low Density land use designation. The Residential Low Density land use designation includes the 18 RC, R-1, and R-4 zones. Prior to approval of a plat without alley access, the Reviewing Official shall evaluate an alley layout and determine that the use of alley(s) is not feasible... 19 6.Alternative Configurations: Offset or loop roads are the preferred alternative configurations. 20 21 7. Cul-de-Sac Streets: Cul-de-sac streets may only be permitted by the Reviewing Official where due to demonstrable physical constraints no future connection to a larger street pattern is physically 22 possible. 23 16. As previously discussed, a through connection by Road A to 162 Ave is not feasible due to the 24 presence of a.wetland and stream on-site. Consequently,.the proposed hammerhead intersection is justified due to environmental constraints as authorized by subsection E(3) above. With the trail 25 linkage to the Cavella trail required by the conditions of approval, the proposal provides for adequate 26 PRELIMINARY PLAT- 14 1 linkage of all pedestrian and vehicular facilities as required by the criteria above. Alley access is not 2 required because the property is Residential Low Density. The criterion above is met. 3 RMC 4-7-150(F): All adjacent rights-of-way and new rights-of-way dedicated as part of the plat, including streets, roads, and'alleys, shall be graded to their full width and the pavement and 4 sidewalks shall be constructed as specified in the street standards or deferred by the 5 Planning/Building/Public Works Administrator or his/her designee. 6 17. As proposed except for the street modification approved by this decision. 7 RMC 4-7-150(G): Streets that may be extended in the event of future adjacent platting shall be required to be dedicated to the plat boundary line. Extensions of greater depth than an average lot 8 shall be improved with temporary turnarounds. Dedication of a full-width boundary street shall be 9 required in certain instances to facilitate future development 10 18. There are no further street extensions possible for the proposed subdivision due to the presence 11 of critical areas. 12 RMC 4-7-170(A): Insofar as practical, side lot lines shall be at right angles to street lines or radial to curved street lines. 13 19. As depicted in Ex.2,the side lines are in conformance with the requirement quoted above. 14 RMC 4-7-170(B):, Each lot must have access to a public street or road.Access may be by private 15 , access easement street per the requirements of the street standards. 16 20. As previously,determined,each lot has access to a public street. 17 RMC 4-7-170(C): The size, shape, and orientation of lots shall meet the minimum area and width 18 requirements of the applicable zoning classification and shall be appropriate for the type of 19 development and use contemplated. Further subdivision of lots within a plat approved through the provisions of this Chapter must be consistent with the then-current applicable maximum density 20 requirement as measured within the plat as a whole. 21 21. As previously determined,,the proposed lots comply with the zoning standards of the R-4 zone, 22 which includes area,width and density. 23 RMC 4-7-170'(D): Width between side lot lines at their foremost points (i.e., the points where the side lot lines intersect with the street right-of-way line)shall not be less than eighty percent(80%) of 24 the required lot width except in the cases of(1)pipestem lots, which shall have a minimum width of 25 twenty feet (20') and (2) lots on a street curve or the turning circle of cul-de-sac (radial lots), which 26 shall be a minimum of thirty five feet(359. PRELIMINARY PLAT- 15 1 22. As shown in Ex.2,the requirement is satisfied. 2 RMC 4-7-170(E): All lot corners at intersections of dedicated public rights-of-way, except alleys, 3 shall have minimum radius offfteen feet(15). 4 23. As conditioned. 5 RMC 4-7-190(A): Due regard shall be shown to all natural features such as large trees, watercourses, and similar community assets. Such natural features should be preserved, thereby 6 adding attractiveness and value to the property. 7 24. The on-site wetland and stream is set-aside from the developed portion of the subdivision. The 8 criteria above is met. 9 RMC 4-7-200(A): Unless septic tanks are specifically approved by the Public Works Department 10 and the King County Health Department, sanitary sewers shall be provided by the developer at no cost to the City and designed in accordance with City standards. Side sewer lines shall be installed 11 eightfeet(8) into each lot ifsanitary sewer mains are available, or provided with the subdivision 12 development. 13 25. As conditioned. 14 RMC 4-7-200(B): An adequate drainage system shall be provided for,the proper drainage of all surface water. Cross drains shall be provided to accommodate all natural water flow and shall be of 15 sufficient length.to permit full-width roadway and required slopes. The drainage system shall be 16 designed per the requirements of RMC 4-6-030, Drainage (Surface Water) Standards. The drainage 17 system shall include detention capacity for the new street areas. Residential plats shall also include detention capacity for future development of the lots. Water quality features shall also be designed 18 to provide capacity.for the new street paving for the plat. 19 26. The proposal provides for adequate drainage that is in conformance with applicable City drainage 20 standards as determined in Finding of Fact No. 4. The City's stormwater standards, which are incorporated into the technical information report and will be further implemented during civil plan 21 review, ensure compliance with all of the standards in the criterion quoted above. 22 . RMC 4-7-200(C): The water distribution system including the locations offire hydrants shall be 23 designed and installed in accordance with City standards as defined by the Department and Fire Department requirements. 24 27.

As conditioned. 24 25 Street Modification 26 PRELIMINARY PLAT- 17 f 1 The existing unimproved right of way width in 162nd• Ave SE is 60 feet. City code requires street improvements along all frontages: Due to existing critical areas which encumber!the right-of-way,the 2 applicant has requested a street modification to eliminate the required landscape planter and sidewalk 3 behind the curb. Additionally,the modification includes a request to not extend frontage improvements past the proposed access street(SE 140th St)of the Liberty Gardens Plat(LUA08-093)across 162nd Ave SE. 1 4 Section 4-4-080.F.10.d allows modifications from the street standards for individual cases, provided the- 5 modification meets the following criteria (pursuant to RMC a.. Will meet the objectives and safety, function, appearance, environmental protection and 6 maintainability intended by the Code requirements, based upon sound engineering judgment;and 7- b.Will not be injurious to other property(ies)in the vicinity;and 8 c.Conform to the intent and purpose of the Code;and 9 d. Can be shown to be justified and required for the use and situation intended;,and 10 e.Will not create adverseimpacts to other property(ies)in the vicinity. The applicant contends that the presence and protection of critical areas located within the 162nd Ave SE 11 right of way would be better served if the proposal does not include full street improvements along the 12 frontage of the site. Staff concurs,the requested modification meets the objective and safety of the code requirements if the required pedestrian path,across•the critical area is provided to connect the development 13 to the existing pedestrian corridor in 162nd Ave SE (see discussion below). The absence of street improvements would not be injurious to the surrounding property owners and can be shown to be justified 14 for the situation intended. Therefore, staff is in support of the requested modification. The staff's factual determinations on this issue are supported by the record and are uncontested. Further, there are no • 15 sidewalks that the proposal could connect to on 162nd Ave SE and no connections are reasonably anticipated 16 in the future. For these reasons,the requested modification is approved. 17 DECISION 18 The proposed preliminary plat and street modification as depicted in Ex.2 and described in this decision 19 is approved, subject to the following conditions: 20 1.

APPLICABLE SECTIONS OF THE COMPREHENSIVE PLAN: 1. Land Use.Element: 2. Transportation Element: 3. Community Design Element: H. FINDINGS OF FACT: 1. The applicant originally requested a Preliminary Plat in order to subdivide a 4.14 acre site into 8 single family lots and two tracts; drainage/sewer, critical areas, (Tracts A & B). The proposal results in a density of 2.5 du/ac(Exhibit 2). 2. The Planning Division of the City of Renton accepted the above master application for review on June 24, 2013. On July 15, 2013 staff determined that the proposal would be required to be processed as a Preliminary Plat. ^While staff received the additional application fees on July 23, 2013 the project was kept on hold due to the need for a mitigation plan for a proposed sewer extension through the critical areas on site. The Planning Division of the City of Renton received supplemental mitigation information for review on January 29, 2014. However on February 24, 2014, staff determined that Independent Secondary Review of provided Critical Area Assessment/Mitigation Plan was needed and the project was placed on hold. On March 6, 2014 the project was revised to eliminate the sewer extension, through the critical area, and the project was taken off hold. The project complies with the 120-day review period. 3:---Mama ca atlit i:s-located northofthe--intersection-of 160th Ave-SE and SE-1415t,Sti-=- --• =_4r :.:, :n ==: 4.

Internal access is proposed via a new dead end road (Road A)which terminates in a hammerhead turnaround. . 9. Topographically, the site can best be characterized as flat sloping down from the northwest to the southeast with a total topographic relief of 14 feet. The steepest slope on the'site is approximately 10% at an isolated location just west of the center of the site. A geotechnical report for the site was HEX Report City of Renton Department of Cor, ;lity&Economic Development i Preliminary Plat Report& Decision MINDY'S PLACE PRELIMINARY PLAT LUA14-000093,PP,ECF,MOD Hearing Date May 13,2014 Page 5 of 13 submitted (exhibit 6). The report states that there are no geotechnical conditions on site that would preclude the proposed development. 10. There are a total of 354 trees located on site of which 45 trees are proposed to be retained outside of the criticalarea and its buffer(Exhibit 3). 11. The applicant submitted a conceptual landscape plan which includes the installation of street trees within a proposed 8-foot planter along the frontage of the internal road (Road 'A') (Exhibit 15). Additional vegetation, two trees per lot, is also proposed on site. Vegetation proposed include: sunset • maple trees. 12. The applicant submitted a Critical Areas Report, prepared by Sewell Wetland Consulting, Inc. (dated February 18, 2013), identifying a portion of a Category 2 wetland located on the subject site (Exhibit 5). Additionally, a Class 4 stream enters the wetland from the north. The stream passes in a culvert through approximately half of the site flowing south and exits the site at the southeast. Category 2 wetlands are required to have a 50-foot buffer measured from the wetland edge. The Class 4 stream is required to maintain a 35-foot buffer which is fully encompassed by the wetland buffer. 13. The report states there are no impacts to the critical areas proposed on site. 14. A drainage plan and drainage report has been submitted,with the application (Exhibit 8). The report addresses compliance with 2009 King County Surface Water Manual and City of Renton Amendments to the KCSWM,Chapters 1 and 2. 15. Pursuant to the City of Renton's Environmental Ordinance and SEPA(RCW 43.2iC, 1971 as amended), on March 24,2014,the Environmental Review Committee issued a Determination of Non-Significance-• _._ Mitigated-(DNS-M)-for-the°Mindy's-Place Preliminary Plat(Exhibit,13).l he DNS M included 2-mitigatio7t Tom-""`^ " v measures.A 14-day appeal period commenced on April 4,2014 and ended on April 18,2014. No appeals of the threshold determination have been filed. 16. Based on an analysis of probable impacts from the proposal, the Environmental Review Committee ERC).issued the following mitigation measures with the Determination of Non-Significance—Mitigated: 1. The applicant shall be best required to record on the face of the Preliminary Plat the maximum amount of square footage of impervious-surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit. 2. The applicant shall submit a secondary review during final engineering design that includes hydro-geotechnical evaluations for buoyancy and lining, structural review and wall drainage relief against potential hydrostatic pressures. The secondary review shall be conducted by an independent reviewer selected by the City at the applicant's expense and shall be approved by the City's Plan Reviewer prior to engineering plan approval. Additionally, the applicant would be required to provide'due diligence in the grading and collection of drainage design during the construction phase so that runoff and erosion does not impact the neighboring properties. 17. Staff received three comment letters by interested parties (Exhibits 9, 10, 11)with questions related to pedestrian access along 162nd Ave SE and drainage concerns in the vicinity of the project. 18. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development.These comments are contained in the official file, and the essence of the comments have been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. 19. The proposal requires Preliminary Plat Review. The following table contains project elements intended to comply with Subdivision Regulations,as outlined in RMC 4-7.

The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies if all conditions of approval are complied with: Policy LU-151. Density should be a maximum of 4 du/ac on portions of the Residential Low Density[designated] land where [environmental] constraints are not extensive and urban densities are.appropriate. Policy LU-157. Within the Residential 4 du/ac zoned area, allow a maximum density of 4 units per. net acre to encourage larger lot development and increase the supply of upper income housing consistent with the City's,Housing Element. Objective CD-C. ;Promote •reinvestment in and upgrade of .existing residential neighborhoods through redevelopment of small, underutilized parcels with infill development, modification and alteration of older housing stock, and improvements to streets and sidewalks,to increase property values. Policy T-9. Streets and pedestrian paths in residential neighborhoods should be arranged as an interconnecting network that serves local traffic and facilitates pedestrian circulation.Compliant if Staff Comment: A pseudo walking trail, constructed as part of the adjacent Cavalla Plat, isConditionsof A roval Met located within the 162nd Ave SE unimproved right-of-way which extends from the subjectpp site to SE 144th St. The proposal does not include a designated pedestrian connection to this trail(See discussion under Compliance With Subdivision Regulations). Policy CD-13. Infilldevelopment should be reflective of the.existing character of esta li neighborhoods even when designed using different architectural st,rles, and /or responding to more urban setbacks, height or lot requirements. Infill development should draw on elements of existing development such as placement of structures,vegetation, and location of entries and walkways,to reflect the site planning and scale of existing areas. 2.COMPLIANCE WITH THE UNDERLYING ZONING DESIGNATION: The site is classified Residential 4 (R-4) on the City of Renton Zoning Map. RMC 4-2-110A provides development standards for development within the R-4 zoning classification.The proposal is consistent with the following development standards if all conditions of approval are complied with or as noted thusly: Density:The allowed density range in the R-4 zone is a maximum of 4.0 dwelling units per acre. There is no minimum density requirement. Staff Comment:After subtracting 14,313 square feet for proposed right-of-way dedications; and 127,745 square feet for critical areas; the net square footage of the site is 138,397 square feet(3.18 net acres). The 8 lot proposal would arrive at a net density of 2.5 dwelling units per acre(8 lots/3.18 acres=2.5'du/ac), which falls within the permitted density range for the R-4 zone. Lot Dimensions: Approval for lot size, width, and depth reductions may be approved when, due to lot configuration or access, four (4) dwelling units per net acre cannot be achieved. The reduction shall be'the minimum needed to allow four(4) dwelling units per net acre and shall be limited to the following minimum dimensions: Lot size—seven thousand two hundred (7,200)sq.ft. Lot width—) sixty feet(60'). Lot depth—seventy feet(70'). Insofar as practical, side lot lines shall be at right angles to street lines or radial to curved street lines. Staff Comment: An Administrative Interpretation (CI-45) eliminating the footnote noted above became effective on January 23, 2014. However, given the applicant originally HEX Report City of Renton Department of co(y, /pity&Economic Development Preliminary Plat Report&Decision MiNDY'S PLACE PRELIMINARY PLAT LUA14-000093,PP,ECF,MOD Hearing Date May 13,2014 Page 7 of 13 submitted the application June 24, 2013 staff is in support of considering the application vested for the purposes of utilizing the provisions of RMC4-2-110D.11. As demonstrated in the table above, all lots meet the requirements;for minimum lot size, depth, and width as outline in RMC 4-2-110D.11 with the exception of Proposed Lots 4 and 6. RMC 4-11-120 defines lot width as the average distance between the side lines connecting front and rear lot lines. It is unclear if proposed Lot 4 and 6 meet the lot width requirement of the zone. Therefore, staff recommends as a condition of approval the applicant be required to demonstrate compliance with the 70-foot lot width requirement for proposed Lots 4 and 6 utilizing the lot width definition pursuant to RMC 4-11-120. Thei average distance between the side lines connecting front and rear lot lines shall be submitted to the Current Planning Project Manager prior to construction permit approval. • Setbacks:The required,setbacks in the R-4 zone are as follows: front yard is 30 feet for the primary structure; interior side yard is 5 feet; side yard along a street is 20 feet for the primary structure;and the rear yard is 25 feet. Staff Comment: The setback requirements for the proposed lots would be verified at the time of building permit review. The proposed lots appear to contain adequate area to provide all the required setback areas. Building Standards: Building height is restricted to 30 feet and, 2-stories. Detached accessory structures must remain below a height of 15 feet and one-story. The allowed building lot coverage for lots over 5,000 SF in size in the R-4 zone is 35 percent or 2,50Q SF, whichever is greater. The allowed impervious surface coverage is 55 percent. Staff Comment: The building standards for the,proposed lots would be verified at the time of buildingz:permi#-review:-T-he-applicant's Preliminary-Drainage-Report•-(Exhibit-=8}=states4that'r- the permeability of the site soils would not meet the standards for infiltration and as a result the drainage report recommends limiting the impervious surface to 49.5%of the site in order to receive the, Reduced Impervious Surface Credit. As part of the Environmental (SEPA) Review determination (Exhibit 13) a mitigation measure will require the applicant record on the face of the Preliminary Plat the maximum amount of square footage of impervious surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit. Landscaping: Ten feet of on-site landscaping is required along all public street frontages, with the exception of areas for required walkways and driveways per RMC 4-4-070. Such landscaping shall include a mixture of trees, shrubs, and groundcover as approved by the Department of Community and Economic Development Compliant if Staff Comment: As proposed the conceptual landscape plan does not comply with the 10- Conditions of foot wide on-site landscape requirement (Exhibit 15). Therefore staff recommends, as a Approval Met condition of approval, the applicant be required to submit a revised landscape plan, depicting a 10-foot wide on-site landscape strip for all lots. The final detailed landscape shall be submitted to and approved by the Current Planning Project Manager prior to construction permit approval. Such landscaping shall include a mixture of trees, shrubs, and groundcdver as approved by the Department of Community and Economic Development. Parking: Each unit is required to accommodate off street parking for a minimum of two vehicles. Staff Comment: Sufficient area exist, on each lot, to accommodate off street parking for a minimum of two vehicles. 3.CRITICAL AREAS:The proposal is consistent with critical area regulations as stated in RMC 4-3-050 if all conditions of approval are met: Compliant if The applicant submitted a Critical Areas Report,prepared by Sewell Wetland Consulting, Inc. HEX Report City of Renton Department of Cc` „amity&Economic Development Preliminary Plat Report&Decision MINDY'S PLACE PRELIMINARY PLAT LUA14-000093,PP,ECF,MOD Hearing Date May 13,2014 Page 8 of 13 Conditions of (dated February 18,2013), identifying a portion of a Category 2 wetland located on the Approval Met subject site(Exhibit 5). Additionally, a class 4 stream enters the wetland from the north. The stream passes in a culvert through approximately half of the site flowing south and exits the site at the southeast. The wetland is vegetated with a mix of red alder,salmonberry and lady fern. Category 2 wetlands are required to have a 50-foot buffer measured from the wetland edge. The Class 4 stream is required to maintain a 35-foot buffer which is fully encompassed by the wetland buffer. The report state there are no impacts to the critical areas proposed on site. However, there does appear to be the tight lining of the proposed drainage facility discharge within the wetland buffer to the stream on site. Additionally,staff will be recommending as a condition of approval the applicant to provide a pedestrian connection across the critical area and its buffer to connect the development to the existing pedestrian corridor in 162nd Ave SE(see discussion under Compliance With Subdivision Regulations-Streets). Trails are permitted in the outer edge of the buffer pursuant to RMC4-3-050M. Critical area impacts are likely as part of proposed tight lining of the drainage on site and to provide recommended pedestrian connectivity to the 162nd Ave SE corridor. The applicant will be required to comply with RMC 4-3-050 Critical Areas'regulations to mitigate for anyimpacts permitted to the wetland buffer. Staff recommends, as a condition of approval, the-applicant submit a Final Mitigation Plan for impacts(tight-lining of drainage system and pedestrian connections)to the critical areas on site or their buffers. The Final Mitigation Plan shall be submitted to and approved by the Current Planning Project Manager prior to utility construction permit a - oval. 'The applicant shall also ablis Nat e,,G tlQl.:a:i' nt over testaryrowtPCotec part of-the site encompassing the stream wetland _ u. e- , at,. p g_. 4, and buffer area and place fencing and signage along the outer buffer.edge. 4.COMMUNITY ASSETS:The proposal is consistent with the following community asset requirements if all condition of approval are complied with: Tree Retention: RMC 4-4-130 states thirty percent of the trees•shall be retained in a residential development. Staff Comment: The eastern portion of the site is covered with dense trees and shrubs. The west is more sparsely vegetated and includes a cleared area where a home once stood. There are a total of 354 trees located on site of which 45 trees are proposed to be retained outside of the critical area and its buffer(Exhibit 3). The applicant is required to retain 30 percent of the trees located on site that are not located within critical areas,proposed rights- of-way and access easements. Of the 354 trees located on site 207 trees would be excluded from the tree retention requirements. Therefore, the applicant would be required to retain at least 41 trees on site. The applicant has proposed to retain 45 trees outside of the critical areas and their buffers and therefore complies with the code(Exhibit 3). 5.COMPLIANCE WITH SUBDIVISION REGULATIONS: RMC 4-7 Provides review criteria for the subdivisions. The proposal is consistent with the following'subdivision regulations if' all conditions of approval are complied with: Access: Each lot must have access to a public street or road.Access may be by private access easement street per the requirements of the street standards. N/A Blocks: Blocks shall be deep enough to allow two tiers of lots. Streets:The proposed street system shall extend and create connections between existing Compliant if streets per the Street Standards outlined in RMC 4-6-060 Street Standards. Conditions of Approval Met Staff Comment:Access to the plat is proposed via 160th Ave SE via a new curb cut,proposed to be improved as part of the plat improvements. The existing right-of-way width in 160th HEX Report City of Renton Departmental Cor;,, ity&Economic Development Preliminary Plat Report&Decision' MINDY'S PLACE PRELIMINARY PLAT LUA14-000093,PP,ECF,MOD Hearing Date May 13,2014 Page 9 of 13 Ave SE is 60 feet. The City's complete street standards require a minimum right of way width of 53 feet for residential access streets. The required street cross-section consists'of a pavement width of 26 feet, a 0.5-foot wide curb, an 8-foot planter strip,5-foot sidewalk, and storm drainage improvements in the right of way fronting the site. Since the existing right- of-way width is 60 feet the applicant would be required to provide a half street paved width of 16 feet,0.5-foot wide curb, 8-foot wide landscaped planter, and a 5-foot wide sidewalk along the frontage of 160th Ave SE. The existing unimproved right of way width in 162nd Ave SE is also 60 feet. City code requires street improvements along all frontages. Due to existing critical areas which encumber the right-of-way the applicant has requested a street modification to eliminate the required landscape planter andsidewalk behind the curb. Additionally, the modification includes a request to not extend frontage improvements past-the proposed access street(SE 140th St) of the Liberty Gardens Plat(LUA08-093)across 162nd Ave SE. Section 4-4-080.F.10.d allows the Administrator to grant modifications from the street standards for individual cases,provided the modification meets the following criteria pursuant to RMC4-9-250.D.2): a.Will meet the objectives and safety,function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment;and b.Will not be injurious to other property(ies)in the vicinity;and c.Conform to the intent and purpose of the Code;and d.Can be shown to be justified and required for the use and situation intended; x v.s.--..r Y,...,-.:..rr-'.,- :'. .>, .`+..':". , an -......,.,._ _::...,-,:_....,,,.- - ' x-= -•--_•.- .--- _. _-;x,:s:a=_cam... .. .... .... . .- .. ..:r-.-:....:.. e.Will not create adverse impacts to other property(ies)in the vicinity. The applicant contends that the presence and protection of critical areas located within the 162nd Ave SE right of way would be better served if the proposal does not include full street improvements along the frontage of the site. Staff concurs the requested modification meets the objective and safety of the code requirements if the required pedestrian path, across the critical area is provided to connect the,development to the existing pedestrian corridor in 162nd Ave$E(see discussion below). The absence of street improvements would not be injurious to the surrounding property owners and can be shown to be justified for the situation intended. Therefore,staff is in support of the requested modification. Internal access is proposed via a new limited residential access road(Road A)which terminates in a hammerhead turnaround. The proposed internal road right of way width of 4.7 feet meets the City street code requirements for a limited residential access street. The proposed internal road section shows a paved width of 20 feet, 0.5-foot wide curbs, 8-foot, wide landscaped planters, and 5-foot wide sidewalks. A pseudo walking trail, constructed as part of the adjacent Cavalla Plat(LUA08-097),is located within the 162"d Ave SE unimproved right-of-way which extends from the subject site to SE 144th St. The proposal does not include a designated pedestrian pathway to this trail. Pursuant to RMC 4-7-150E.2 linkages including pedestrian paths,shall be provided within and between neighborhoods when they can create a continuous and interconnected network of roads and pathways. Therefore staff recommends, as a condition of approval, the applicant be required to provide a pedestrian connection across the critical area to connect the development to the existing pedestrian corridor in 162nd Ave SE as a means of pedestrian connectivity between neighborhoods. The revised plat plan shall be submitted to, and approved by, the Current Planning Project Manager prior to construction permit HEX Report City of Renton Department of Cc i,_.,`lnity&Economic Development Preliminary Plat Report&Decision MINDY'S PLACE PRELIMINARY PLAT LUA14-000093,PP,ECF,MOD Hearing Date May 13,2014 Page 10 of 13 approval. it is also anticipated that the proposed project would result in impacts to the City's street system. In order to mitigate transportation impacts the applicant would be required to pay an appropriate Transportation Impact Fee. Currently this fee is assessed at$1,403.72 per net new single family home. Relationship to Existing Uses:The proposed project is compatible with existing surrounding. uses. Staff Comment: The properties surrounding the subject site are single-family residences and are designated R-4 on the City's zoning map. The proposal is similar to existing development patterns in the area and is consistent with the,Comprehensive Plan and Zoning Code, which encourage residential infill development. 6.AVAILABILITY AND IMPACT ON PUBLC SERVICES: Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development; subject to the provision of Code required improvements and fees. A Fire Impact Fee; based on new single family lots, will be required in order to mitigate the proposal's potential impacts to City emergency services. The fee is payable'to the City as specified by the Renton Municipal Code. Currently the fee is assessed at$488.00 per single family residence. Schools: lt.is anticipated that the Issaquah School District can accommodate any additional students generated by this proposal at the following schools: Briarwood Elementary (1.51 miles from the subject site), Maywood Middle School (0.75 miles from the subject site) and Liberty High School (1.49 miles from the subject site). RCW 58.17.110(2) provides that no fir =;_ -_.subdivision.;be.,appraved..without:making.a-written,finding-of.adequate..provisipn madefor safe walking conditions for students who walk to and from school. While the designated schools are located within a close proximity of the subject site future students are designated to be transported to school via bus. The bus stop for all three schools would be located at 160th Ave SE at SE 137th Place (Exhibit 15). it appears there are not designated walkways for portions of 160th Ave SE between the subject site and the designated bus stop. Therefore, 'staff recommends as a condition of approval the applicant be required to demonstrate safe walking conditions for students from the subject plat to the designated bus stop at 160th Ave SE at SE 137th Place prior to construction permit approval. This may include a dedicated shoulder, curb, or some other alternative as determined by the CurrentCompliantif Planning Division.Conditions of Approval Met Additionally, staff has recommended the applicant be required to provide a pedestrian connection across the critical area to connect the development to the existing'pedestrian corridor in 162nd Ave SE as a means of pedestrian connectivity between neighborhoods (see discussion above under Compliance with Subdivision Regulations). This pedestrian connection would also potentially serve to further comply with the safe routes to school program by providing walking alternatives to schools within the vicinity of the subject site. Per RCW 47.04.300 planning, development, and implementation of projects and activities should improve safety and reduce traffic,fuel consumption, and air pollution in the vicinity,of schools by providing walking alternatives to schools. A School impact Fee, based on new single family lots, will also be required in order to mitigate the proposal's potential impacts to Issaquah School District. The fee is,payable to the City as specified by the Renton Municipal Code. Currently the fee is assessed at 5,730.00 per single family residence.

Approval Met The site is located within the Lower Cedar River Basin of the Cedar River. The site slopes to east to a low point near the center of the property where it generally drains to the south/southeast. The site received surface water runoff approximately 10 acres of off- site property to the north. Stormwater enters the"site via sheet flow along the northern property line and presently discharges asan intermittent Class 4 stream near the southeast of the property. The stream then travels across the 162nd Ave SE right-of-way onto.the Liberty Gardens plat(LUA08-093). The water then continues to flow south and then enters back into the 162nd Ave SE right-of-way where it is collected in an 18-inch pipe. The pipe is conveyed under the newly constructed sewer access road in 162nd Ave SE and then empties into a stormwater pond at the intersection of 162nd Ave SE and SE 144th St. The applicant submitted a Preliminary Drainage Report prepared by Daley-Morrow-Poblete, Inc., dated March 25,2013(Exhibit 8). The report states that the runoff from the proposed project would be collected and conveyed by a catch basin/pipe network to a detention pond on the southern edge of the developed area. The proposed facility would then discharge into the onsite stream. The storm pond is designed per the 2009 King County Surface Water Design Manual as amended by the City of Renton. The report states that the project'should not pose significant negative impacts to the downstream drainage'course and all core and six special requirements are contained in the report. However,staff received comments,from surrounding property owners, with respect to drainage concerns for the proposal and the surrounding areas(Exhibits 9, 10, 11). There have also been identified existing drainage problems in the area and the potential for the applicant is,proposippggdrainageproblems.

However, due to potential seepage in and out of the pond, additional secondary review is,required per the Determination of Non-Significance-Mitigated(DNS-M)during final engineering design that includes hydro-geotechnical evaluations for buoyancy and lining, structural review and wall drainage relief against potential hydrostatic pressures(Exhibit 13). The secondary review will be required to be'conducted by an independent reviewer selected by the City at the applicant's expense and shall be approved by the City's Plan Reviewer prior to engineering plan approval. Additionally, the applicant would be required to be provide due diligence in the grading and collection of drainage design during the construction phase so that runoff and erosion does not impact the neighboring properties. The applicant should take note that the drainage report states that the permeability of the site.soils will not meet the standards for infiltration and as a result the drainage report recommends limiting the impervious surface to 49.5%of the site in order to receive the Reduced impervious Surface Credit. Therefore the Determination of Significance—Mitigated DNS-M)included a mitigation measure requiring the applicant to record on the face of the Preliminary Plat the maximum amount of square footage of impervious surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit(Exhibit 13). Finally, an existing administrative interpretation requires all drainage facilities be required to maintain up to a 15-foot vegetated buffer around drainage pond facilities(Exhibit 12). Therefore,staff recommends as a condition of approval the applicant be required to submit a revised landscape plan, depicting up to a 15-foot landscape buffer around the proposed drainage facility.

EXHIBIT 9 I, Rocale Timmons, Senior Planner Mindy's Place 14020 160th Ave SE My property at 14120 adjoins this development. Plot says that a 4 foot wire fence is being used between my property and this development. This is not acceptable. A 6 foot wood fence should be used just like all the other developments in the area. A four foot fence is certainly not acceptable along the south border of the pond. Any child can get over;a 4 foot fence and into that pond. Where do you plan to put,the water from that pond? I see you dumping the water into my property since the pond is located next to the low spot on my property. This water should go down 160th or some other solution that does not)involve my property. Your plot does not show where the water is to be routed. Why is the sewer line running through the wet lands to 162th when it could much easier be connected to the sewer on 160th?This would save the wet lands from damage. How can you count(sidewalks and planting strips as part of the road. The only r.. like 160th rightrealroadisonl20feetwide.. It also looks the curbs are in.the away and will be run into by cars. Where did the ditches on the road go? From where I stan,d on the other side of the 4 foot fence this short plat needs more work and should not be accepted as is.

BACKGROUND:The current drainage code (RMC 4-6-030) references the current King County Surface Water Design Manual (KCSWDM)for compliance with stormwater standards. Requirements for landscaping in stornwater facility tracts are included in Section 5.3.1.1 of the 2009 KCSWDM as amendeckby the-City-of Renton: -Section 5:3:1.1 of-the-KC5-WDM restricts---; planting in berms that impound water or within 10 feet of any structure. Requirements for pond geometry and side slopes are listed in Section 5.3.1.1 of the 2009 KCSWDM, as amended by the City of Renton. Adopted standards allow for the side slopes of an open detention or water quality treatment facilities(pond,wetpond, stormwater wetland, etc)to be steeper than 3:1 if a fence is provided along the wall and/or around the emergency"overflow water surface elevation.This standard is resulting in facilities that are difficult to maintain, expensive in labor and materials for maintenance,and create a safety hazard to the maintenance crews. Fencing requirements are also standardized in section 5.3.1.1 of the 2009 KCSWDM, as amended by the City of Renton.A fence is required to discourage access to the stormwater pond, prevent litter, allow efficient maintenance, and in consideration of worker and public safety., JUSTIFICATION:Recognizing that requirements for landscaping and tree planting' contribute to the aesthetics and value of new surface water installations while needing to ensure proper functionality and maintenance of facilities, both the Department of Public Works and the Department of Community and Economic Development desire to clarify standards H:\CED\Planning\Title IV\Docket\Administrative Policy Code Interpretation\CI-38\I EXHIBIT 12 C 1 r pertaining to the landscaping requirements applicable to stormwater facilities: Concerns for public safety have also raised questions regarding the. y necessity of more extensive fencing requirements for drainage facilities as well as lesser side slopes for flow control and/or water quality treatment ponds. This interpretation is intended to provide guidance and consistency for projects currently under review. DECISION: Briefly,this determination clarifies: Fencing Requirements:. All flow control and/or water quality treatment ponds shall be fenced. Fence material shall be six foot black or green: coated chain link. Cedar or other materials may be.,installed only if owned and maintained by a private property owner or Home Owner's Association (HOA). Landscaping Requirements: Landscaping is required in those areas of the tract/easement'that will not impact the functionality or maintenance of the facility. The fence shall be placed at the top of the berm with the maintenance access road in the inside of the fence; or 5 feet min from top of berm if there is no maintenance access road to allow access for w--proper•maintenanceDfthe•facility.sNo•landsc;aping-shell be planted-inside- the fence line. Pond Geometry and Side Slope Requirements: Side slopes (interior and exterior) shall not exceed three (3) feet horizontal one foot (1)vertical. The full text of all clarified rules regarding fencing, side slopes, and landscaping in storm drainage facilities is attached as Attachment A.

REFERENCE: N/A SUBJECT: Removal of footnote 11 which provides for reduced lot dimensions in the R-4 zone when subdivisions cannot achieve a density of 4 dwelling units per squareiacre. BACKGROUND:4-2-110D, footnote 11 addresses lot size,width and depth reductions in R-4 zones when, due to lot configuration or access,four(4) du/ac cannot be achieved.The footnote allows minimum reduction needed to allow._. four(4du/ac using the following minimum dimensions: Lot size-Seven thousand two hundred (7,200 sq.ft.) Lot width-Sixty feet (60') Lot depth—Seventy feet(70') JUSTIFICATION:The footnote was improperly applied to R-4 zones to allow reductions in net density. However, no reduction is needed to meet minimum of four 4) du/ac because R-4 zones have no minimum density requirements and a maximum density of four(4) du/ac.Allowing lot reduction in R-4 zones is not in accordance with the City's Comprehensive Plan which states in Objective LU-157 that"Within the residential 4 du/acre zoned area allow a maximum density of 4 units per net acre to encourage larger lot development and increase the supply of upper income housing consistent with the City's Housing Element." Reducing lot dimensions allows for additional,units on lots that already meet the intent of zone densities effectively resulting in a higher than desired density situation. DECISION: RMC 4-2-110D,footnote 11 shall be removed from RMC 4-2-110A and marked as deleted in RMC 4-2-110D as it pertains to R-4 zones.

However, due to the number of lots/tracts a Preliminary Plat was required. The applicant is now requesting Environmental Review and a Preliminary Plat approval for the subdivision of the 4.14 acre parcel into 8 lots for the future construction of single family residences and two tracts for critical areas and drainage. The site is currently vacant. The project site is located within the Residential - 4 (R-4) dwelling units per acre zoning classification. The proposed lots would all have a lot size ranging from 7,200 square feet to 7,733 square feet. Access to all lots would be provided via private driveways from a new proposed public road'extended from 160th Ave SE which terminates in a hammerhead turn-around. The applicant is requesting a street modification, from RMC 4-4-060, in order reduce the width of the hammerhead turnaround to 20 feet and eliminate frontage improvements along 162nd Ave SE. The site contains a Category 2 wetland and Class 4 stream. The applicant originally requested a Variance from RMC 4-3-050 in order to place a sewer extension through the wetland and its buffer but has later revised the proposal to connect to sewer in 160th Ave SE and avoid impacts to critical areas.

The vacant project site is located within the Residential - 4 (R-4)" dwelling units per acre zoning classification. The proposed lots would range in size from 7,200square feet in area to 7,733 square feet. The site is located north of the intersection of 160th Ave SE and SE 141sY St. The subject site is generally rectangular in shape and is bordered by existing residential properties to the north and south. To the east, across unimproved 162nd Ave SE, is an approved Preliminary Plat (Liberty Gardens, LUA08-093). The west is bordered by 160th Ave SE. Access to the plat is proposed via 160th Ave SE via one new curb cut, which is proposed to be improved as part of the plat improvements. Internal access is proposed via.a new dead end road (Road A) which terminates in a hammerhead turnaround. The western portion of the site is a cleared area and the eastern half of the site is heavily forested. A large portion of a Category 2 wetland is located on the northeastern portion of the site as well as a Class 4 stream. The original proposal included the extension of a sewer main through the critical areas on site in order to utilize a gravity main. The project was later revised to extend sewer from 160th Ave SE; using pump grinders for two lots. The applicant is proposing to avoid all critical areas on site. There are a total of 354 trees located on site of which 45 are(proposed to be retained outside of the critical area and buffer. The stormwater detention facility is proposed on the south side of the site with a concrete retaining wall around the south and northeast side of the pond. The proposal is anticipated to have approximately 200 cubic yards of cut to be balanced on site.i Staff received three comment letters by; interested parties (Exhibits 9, 10, 11) with questions related to pedestrian access along 162nd Ave SE and drainage concerns. In compliance with RCW 43.21C.240,the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period. B. Mitigation Measures 1. The applicant shall be best required to record on the face of the Preliminary Plat the maximum amount of square footage of impervious surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has-adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The site can best be characterized as flat sloping down from the northwest to the southeast with a total topographic relief of 14 feet. The steepest slope on the site is approximately 10% at an isolated,location just west of the center of the site. The applicant is proposing excavation in the amount of approximately 200 cubic yards to be balanced on site. The applicant submitted a Geotechnical Report prepared by Robinson Noble, dated April 9, 2013 Exhibit 6). The report states that there are no geotechnical conditions on site that would preclude the proposed development. The soils on site were classified as Alderwood gravelly loam. Shallow groundwater seepage was not encountered. The applicant will be required to design a Temporary Erosion and Sedimentation Control Plan TESCP) pursuant to the 2009 King County Surface Water Design Manual Erosion and Sediment Control Requirements. Mitigation Measures: No further mitigation required. , Nexus: Not applicable ERC Report.docx City of Renton Department of Community&Economic Development environmental Review Committee Report MINDY'S PLACE PRELIMINARY PLAT LUA14-000093(AKA LUA13-000725),ECF,PP, Report of March 24,2014 Page 4 of 8 2. Water a. Wetland, Streams, Lakes Impacts: The applicant submitted a Critical Areas Report, prepared by Sewell Wetland Consulting, Inc. (dated February 18, 2013), identifying a portion of a Category 2 wetland located on the subject site (Exhibit 5). Additionally, a class 4 stream enters the wetland from the north. The stream passes in a culvert through approximately half of the site flowing south and exits the site at the southeast. The wetland is vegetated with a mix of red alder, salmonberry and lady fern. Category 2 wetlands are required to have a 50-foot buffer measured from the wetland edge. The Class 4 stream is required to maintain a 35-foot buffer which is fully encompassed by the wetland buffer. The report state there are no impacts to the critical areas proposed on site. However, there does appear to be the tight lining of the proposed drainage facility discharge within the wetland buffer to the stream on site; Additionally, as part of the Preliminary Plat staff may recommend a condition to provide a pedestrian connection across the critical area to_connect the development to the existing pedestrian corridor in 162nd Ave SE as a means of connectivity and a safe route to schools. Ifimpacts are proposed for the tight lining of the drainage on site, or required in order to provide pedestrian connectivity, the proposal would'be conditioned as part of the Preliminary Plat approval to provide a'mitigation plan for associated impacts prior to the approval of construction permits. In order to preserve and protect the wetland and its buffer the applicant will be required as part of the Preliminary Plat approval, to iestablish a Native Growth Protection Easement over that part of the site encompassing the stream/wetland and buffer area. Conditions associated with Preliminary Plat approval will likely include wetland signage and fencing and potential review and approval of a final wetland mitigation plan. Mitigation-Measures: No further'mitigation needed Nexus: Not applicable b. Storm Water Impacts: The site is located within the Lower Cedar River Basin of the Cedar River. The site slopes to east to a low point near the center of the property where it generally drains to the south/southeast. The site received surface water runoff from approximately 10 acres of off-site property to the north.';Stormwater enters the site via sheet flow along the northern property line and presently discharges as an intermittent,Class 4 stream near the southeast of the property., The stream then travels across the 162nd Ave SE right-of-way. onto the Liberty Gardens. plat (LUA08- 093). The water then continues to flow south and then enters back into the 162nd Ave SE right-of- way where it is collected in' an 18-inch pipe. The pipe is conveyed under the newly constructed sewer access road in 162nd Ave SE and then empties into a stormwater pond at the intersection of 162nd Ave SE and SE 144th St. J 1. r The applicant submitted a Preliminary Drainage Report prepared by.Daley-Morrow-Poblete, Inc., dated March 25, 2013 (Exhibit 8). The report states that'the runoff from the proposed project would be collected and conveyed by a catch basin/pipe network to a detention pond on the southern edge of the developed area. The proposed facility would then discharge into the onsite stream. 'The storm pond' is designed per the 2009 King County Surface Water Design Manual as amended by the City,of Renton. ERC Report.docx City of Renton Department of Community&tconomic Development environmental Review Committee Report MINDY'S PLACE PRELIMINARY PLAT LUA14-000093(AKA LUA13-000725),ECF,PP, Report of March 24,2014 Page 5 of 8 The report states that the project should not pose significant negative impacts to the downstream drainage course and all core and six special requirements are contained in the report. However, staff received comments, from surrounding property owners, with respect to drainage concerns for the proposal and the surrounding areas. There have also been identified existing drainage problems in the area an d the potential for the proposal to aggravate existing or create new drainage problems. The applicant is proposing to include ,a pond wall of approximately 4-feet in height with flow control staging against the wall. However, due to potential seepage in and out of the pond, additional secondary review is'recommended during final engineering design that includes hydro-geotechnical evaluations for buoyancy and lining, structural review and wall drainage relief against potential hydrostatic pressures. The secondary review shall be conducted by an independent reviewer selected by the City at the applicant's expense and shall be approved by the City's Plan Reviewer prior to engineering plan approval. Additionally, the applicant would be required to be provide due diligence in the grading and collection of drainage design during the construction phase so that runoff and erosion does not impact the neighboring properties. The applicant should take note that the report states that the permeability of the site soils will not meet the standards for infiltration and as a result the drainage report recommends limiting the' impervious surface to 49.5% of the site in order to receive the Reduced Impervious Surface Credit. Therefore, staff recommends a mitigation measure requiring the applicant be required to record on the face of.the, Preliminary Plat 'the maximum amount of square footage of impervious surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit. Additionally, an existing administrative interpretation requires all drainage facilities be required to maintain a 15-foot vegetated buffer around drainage pond facilities (Exhibit 12). Conditions associated with Preliminary Plat approval will likely include the requirement to submit a revised landscape plan, prior to recording of the Plat, depicting a 15-foot landscape buffer around the proposed drainage facility. Mitigation Measures: 1. The applicant shall be required to record on the face of the Preliminary Plat the maximum amount of square footage of impervious surface allowed for each new lot if less than allowed by code if the applicant intends to utilize the Reduced Impervious Surface Credit. 2. The applicant shall submit a secondary review during final engineering design that includes hydro-geotechnical evaluations for buoyancy and lining, structural review and wall drainage relief against potential hydrostatic pressures. The secondary review shall be conducted by an independent reviewer selected by the City at the applicant's expense and shall be approved by the City's Plan Reviewer prior to engineering plan approval. Additionally, the applicant would be required to be provide due diligence in the grading and collection of drainage design during the construction phase so that runoff and erosion does not impact the neighboring properties. Nexus: SEPA Environmental Regulations and RMC 4-6-030 Drainage (Surface Water Standards) 3. Vegetation Impacts: The eastern portion of the site is covered with dense trees and shrubs. The west is more sparsely vegetated and includes a cleared area where a home once stood. There are a total of 354 trees located on site of which 45 trees are proposed to be retained outside of the critical area and ERC Report.docx City of Renton Department of Community&economic Development c,ivironmental Review Committee Report MINDY'S PLACE PRELIMINARY PLAT LUA14-000093(AKA LUA13-000725),ECF,PP, Report of March 24, 2014 Page 6 of 8 its buffer (Exhibit 3). The applicant is required to retain 30 percent of the trees located on site that are not located within critical areas, proposed rights-of-way and access easements. Of the 354 trees located on site 207 trees would be excluded from the tree retention requirements., Therefore, the applicant would be required to retain at least 41 trees on site. The applicant has only proposed to'retain 45 trees outside of the critical areas and their buffers and therefore complies with code (Exhibit 3). Mitigation Measures:,No further mitigation needed Nexus:,Not"applicable 4. Transportation, Impacts: Access to the plat is proposed via 160th Ave SE via a new curb cut, which is proposed to be improved as part of the plat improvements. The existing right-of-way width in 160th Ave SE is 60 feet. The City's complete street' standards require a minimum right of way width of 53 feet for residential access streets. The required street,cross-section consists of a pavement width of 26 feet, a . 0.5-foot wide curb, an 8-foot planter strip, 5-foot sidewalk, and storm drainage improvements in the right of way fronting the site. Since the existing right-of-way width is 60 feet the applicant would be required to provide a half street paved width of 16 feet, 0.5-foot wide curb, 8-foot wide landscaped planter, and a 5-foot wide sidewalk along the frontage of 160th Ave SE. The existing unimproved right of way width in 162nd Ave SE is also 60 feet. City code requires street improvements,along all frontages. Due to existing•critical areas which encumber the right-of-way the applicant has requested a st ieet modification to eliminate the required.landscape planter and sidewalk behind the proposed curb. Additionally, the modification includes a request to not extend frontage improvements past the proposed access street (SE 140th St) of the Liberty Gardens Plat LUA08-093). A 20-foot pavement section and 0.5 foot wide curb on the east side of 162nd Ave SE is proposed as part of the Liberty Gardens Plat up to the SE 140th St/162nd Ave SE intersection. Staff is in support of the modification and will likely recommend a condition of the Preliminary Plat approval to construct the required pavement width and curb,on SE 162nd Ave if the cross section is not already constructed as part of the Liberty Gardens Plat. Internal access,is proposed via a new limited residential access road (Road A) which terminates in a hammerhead turnaround. The proposed internal road right of way width of 47 feet meets the City street code requirements for a limited residential access street. The proposed internal road section shows a paved width of 20 feet, 0.5-foot wide curbs, 8-foot wide landscaped planters, and 5-foot wide sidewalks. ' It is anticipated that the proposed project would result in impacts to the City's street system. In order to mitigate transportation'impacts the applicant would be required to pay an appropriate Transportation Impact Fee. Currently this fee is assessed at $1,403.72 per net new single family home. The fee, as determined by the Renton .Municipal Code at the time of building permit issuance shall be payable to the City. Mitigation Measures: No further mitigation needed Nexus: Not applicable E. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers.

Plot says that a 4 foot wire fence is being used between my property and this development. This is not acceptable. A 6 foot wood fence should be used just like all the other developments in the area. A four foot fence is certainly not acceptable along the south border of the pond. Any child can get over a 4 foot fence and into that pond. Where do you plan to put the water from that pond? I see you dumping the water into my property since the pond is located next to the low spot on my property. This water should go down 160th or some other solution that does not involve my property. Your plot does notshow where the water is to be routed. Why is the sewer line running through the wet lands to 162th when it could much easier be connected to the sewer on 160th?This would save the wet lands from damage. How can you count sidewalks and planting strips as part of the road. The real road is only 20 feet wide. It also looks like the curbs are in the 160th right, away and will be run into by cars. Where did the ditches on the road go? From where I stand on the other side of the 4 foot fence this short plat needs more work and should not be accepted as is.

Currently,the two ponds at 160th empty into a ditch at the side of the street and the water eventually run toward our properties. The runoff has caused soil erosion in our properties. We are thus very concerned that there will be additional volume from Mindy's Place. Please,address this issue in the plans for Mindy's Place. We would appreciate information regarding surface water on this property as plans progress.

Section 5.3.1.1 of the KCSWDM restricts planting in,berms that\impound water or within 10 feet of any structure. Requirements for pond geometry and side slopes are listed in Section 5.3.1.1 of the 2009 KCSWDM, as amended by the City of Renton.Adopted standards allow for the side slopes of an open detention or water quality treatment facilities (pond, wetpond, stormwater wetland, etc)to be , steeper than 3:1 if a fence is provided along the wall and/or around the emergency overflow water surface elevation.This standard is resulting in facilities that are difficult to maintain, expensive in labor and materials' for maintenance, and create a safety hazard to the maintenance crews. Fencing requirements are also standardized in section 5.3.1.1 of the 2009 KCSWDM, as amended by the City of Renton. A fence is required to discourage access to the stormwater pond, prevent litter, allow efficient maintenance, and in consideration of worker and public safety. JUSTIFICATION:Recognizing that requirements for landscaping and tree planting contribute to the aesthetics and value of new surface water installations while needing to ensure proper functionality and maintenance of facilities, both the Department of Public Works and the Department of Community and Economic Development desire to clarify standards H:\CED\Planning\Ttle IV\Docket\Administrative Policy Code Interpretation\CI-38\I EXHIBIT 12 pertaining to the landscaping requirements applicable to stormwater facilities. Concerns for public safety have also raised questions regarding the necessity of more extensive fencing requirements for drainage facilities as well as lesser side slopes for flow control and/or water quality treatment ponds. This interpretation is intended to provide guidance and consistency for projects currently under review. DECISION: Briefly, this determination clarifies: Fencing Requirements: All flow control and/or water quality treatment ponds shall be fenced. Fence material shall be six foot black or green coated chain link. Cedar or other materials may be installed only if owned and maintained by a private property owner or Home Owner's Association (HOA). Landscaping Requirements: Landscaping is required in those areas of the tract/easement that will not impact the functionality or maintenance of the facility. The fence shall be placed at the top of the berm with the maintenance access road in the inside of the fence; or 5 feet min from top of berm if there is no maintenance access road to allow access for proper maintenance of the facility. No landscaping shall be planted inside the fence line. Pond Geometry and Side Slope Requirements: Side slopes(interior and exterior) shall not exceed three (3) feet horizontal one foot (1)vertical. The full text of all clarified rules regarding fencing, side slopes, and landscaping in storm drainage facilities is attached as Attachment A. DEVELOPMENT SERVICES DIRECTOR APPROVAL Neil Watts UTILITY SYSTEMS DIRECTOR APPROVAL Lys Hornsby DATE: February 4, 2013 APPEAL PROCESS:To appeal this determination, a written appeal accompanied by the required filing fee--must be filed with the City's Hearing Examiner(1055 South Grady Way, Renton,WA-98057, 425-430-6515) no more than 14 days from the date of this decision.

The City of Renton does not accept public dedications by short plat recording. Dedications are done by separate instrument concurrent with the recording of the short plat as evidence by the attached recording numbers. 2. The City of Renton has taken over the ownership and maintenance of storm drainage facilities that would require dedication of the storm pond to the City. 3. If the storm pond and public right-of-way are dedicated to the City concurrent with the recording of the final short plat then no storm tract will be created by the final short plat. If this is the course that is taken then the project, as demonstrated on the attached tentative short plat, would create 8 lots and 1 Tract for NGPE purposes and would therefore be a short plat. Please let me know if you have any question regarding this and how the City would view this. i Thank you ( y.M.P.,Inc.

However, in practicality the Critical Areas always end up in tracts(in this case a separate tract) because: 1.) If placed in an easement applicants are unable to record the information necessary(delineated wetland boundaries, buffers,etc.) when solely within an easement; and 2.) City has taken over maintenance of the storm drain improvements so for clarity of responsibility they have been placed in separate tracts and not easements.they have been requiring that they be placed in their own tracts.

The private easement has been eliminated..A public road terminating in hammer head is being proposed. We have provided a sidewalk on the north side of the proposed road that terminates at the turnaround with 20' of pavement width as required by fire. Per RMC 4-2-110D, footnotes 11 and 12 this layout will also not need to go through any lot clustering "provisions/requirements" if the Reviewing Official will allow the reductions described in the footnotes. The critical area buffers and inaccessible area for development impact the developable are to an extent that the reductions would be needed to achieve the maximum density permitted with the use of these footnotes. Please let me know your take on this lay out and what can be done satisfy any of the City's concerns. Thanks D.M.P.,Inc. .

Last week I met with Dave Christensen of the City's sanitary sewer department to discuss the possibility of serving the project from 160th Ave.SE. We determined that we can gravity serve all the lots except for proposed lots 4 and 5.These two lots will require grinder pumps. Mr. Christensen felt that if most of the lots could be served by gravity that in the long run it would be in the City's best interest as it would eliminate a sewer main that would be in a sensitive area that could cause maintenance issues in the future. We have revised the conceptual utilities, drainage control, grading and road profile sheets to reflect the new sanitary sewer route. The landscape plan did not change nor did the preliminary plat page. We would like to with draw the sensitive areas variance and proceed with the plat as now proposed. 5 copie e revised sheets have been provided as well as 8%x 11 reductions.

Currently,the two ponds at 160th empty into a ditch at the side of the street and the water eventually run toward our properties. The runoff has caused soil erosion in our properties. We are thus very concerned that there will be additional volume from Mindy's Place. Please address this issue in the plans for Mindy's Place. We would appreciate information regarding surface water on this property as plans progress.

Plot says that a 4 foot wire fence is being used between my property and this development. This is not acceptable. A 6 foot wood fence should be used just like all the other developments in the area. A four foot fence is certainly not acceptable along the south border of the pond. Any child can get over a 4 foot fence and into that pond. Where do you plan to put the water from that pond? I see you dumping the water into my property since the pond is located next to the low spot on my property. This water should go down 160th or some other solution that does not involve my property. Your plot does not show where the water is to be routed. Why is the sewer line running through the wet lands to 162th when it could much easier be connected to the sewer on 160th?This would save the wet lands from damage. How can you count sidewalks and planting strips as part of the road. The real road is only 20 feet wide. It also looks like the curbs are in the 160th right away and will be run into by cars. Where did the ditches on the road go? From where I stand on the other side of the 4 foot fence this short plat needs more work and should not be accepted as is.

However,due to the number of lots/tracts a Preliminary Plat is required. Additionally,revisions to the proposal include proposed impacts to the critical areas on site necessitating a • Variance. The applicant is now requesting Environmental Review and a Preliminary Plat approval for the subdivision of the 4.14 acre parcel into 8 lots for the future construction of single family residences and two tracts for critical areas and drainage. The site is currently vacant. The project site is located within the Residential-4(R-4)dwelling units per acre zoning classification.The proposed lots would all have a lot size ranging from 7,200 square feet to 7,733 square feet. Access to all lots would be provided via private driveways from a new proposed public road extended from 160th Ave SE which terminates in a hammerhead turn-around. The applicant is requesting a street modification,from RMC 4-4-060,in order reduce the width of the new public street from the required 53 feet to 47 feet. The site contains a Category 2 wetland. The applicant is requesting a Variance from RMC 4-3-050 in order to place a sewer extension through the wetland and it's buffer. LUA13-000725 was placed on hold by the Planner on 7/15/13 as the project requires Preliminary Plat approval and a critical areas variance for a sewer line to cross a wetland. 1/24/14 the applicant submitted the final parts of the supplemental information/fees required. However,we were unable to link the plan cases in Ener1gov therefore a new LUA was created (LUA14-090093). 2/24/14-the project was•placed back•on hold pending secondary review of the wetland analysis and mitigation plan. 3/6/14-project was revised to eliminate the sewer extension through to 162nd Ave SE.

Last week met with Dave Christensen of the City's sanitary sewer department to discuss the possibility of serving the project from 160th Ave.SE. We determined that we can gravity serve all the lots except-for proposed lots 4 and 5.These two lots will require grinder pumps. Mr. Christensen felt that if most of the lots could be served by gravity that in the long run it would be in the City's best interest as it would eliminate a.sewer main that would be in a sensitive area that could cause maintenance issues in the future. We have revised the conceptual utilities, drainage control, grading and road profile sheets to reflect the new sanitary sewer route. The landscape plan did not change nor did the preliminary plat page. We would like to with draw the sensitive areas variance and proceed with the plat as now proposed. 5 copie e revised sheets have been provided as well as 8%Z x 11 reductions.

No impacts to these critical areas or their buffers are proposed from the design of the plat. However, temporary impacts to the wetland and buffer are required to connect the site to the sewer main located east of the site. Under City of Renton Municipal Code (RMC) Chapter 4-3-050.M.8; 8. Wetland Changes -Alternative Methods of Development: If wetland changes are proposed for a non-exempt activity, the applicant shall evaluate alternative methods of developing the property using the following criteria in this order and provide reasons why a less intrusive method of development is not feasible. In determining whether to grant permit approval per subsection M2 of this Section, General Standards for Permit Approval, a determination shall be made as to whether the feasibility of less intrusive methods of development have been adequately evaluated and that less intrusive methods of development are not feasible. (Ord. 5676, 12-3-2012) a. Avoid any disturbances to the.wetland or buffer; Avoiding the disturbance to the wetland and buffer is not possible.

Minimize any wetland or buffer impacts; The proposed sewer line will cross the wetland and buffer in the narrowest area possible creating the least impact possible. The area of temporary disturbance is a 10'wide area that is large enough to get an excavator through the area. c. Restore any wetlands or buffer impacted or lost temporarily; and The proposed restorations includes the replacement of topsoil within the excavated sewer line area to the original grades, and replanting with a dense layer of native trees and shrubs to restore the function and plant community to this area. :All work will be in the dry season and will minimize impacts to the critical areas. d. Compensate for any permanent wetland or buffer impacts by one of the following methods: i. Restoring a former wetland and provide buffers at a site once exhibiting wetland characteristics to compensate for wetlands lost; Not applicable, all wetland and buffer area disturbed will be restored to original condition with no loss of area or function. ii. Creating new wetlands and buffers for those lost; and NA i iii. In addition to restoring or creating a wetland, enhancing an existing degraded wetland to compensate for lost functions and values.

The area of temporary disturbance is a 10'wide area that is large enough to get an excavator through the area. d. The need for the variance is not the result of actions of the applicant or property owner; and The need for the variance is the result of the only available sewer line being located to the east of the property. e. The proposed variance is based on consideration of the best available science as described in WAC 365-195-905; or where there is an absence of valid scientific information, the steps in RMC 4-9-250F are followed. The proposed variance is based upon minimizing critical areas impacts to the minimum required to get the sewer line connection. The area will be mitigated using the best available science to include replacement of topsoil within the excavated sewer line area to the original grades, and replanting with a dense layer of native trees and shrubs to restore the function and plant community to this area. All work will be in the dry season and will minimize impacts to the critical areas. As required under this section of Code, the wetland impact in addition to being restored will be enhanced at a 2:1 ratio on top of the restoration. The restored wetland and buffer will be monitored 4 times in Year 1, and once a year for 5 years as required by Code. Lakeridge-Mindy s Place Sewall Wetland Consulting,Inc.

Zoning Designation of the Site and Adjacent Properties R-4, Residential 4 du/ac Current Use of the Site andiany Existing improvements The site is currently vacant;and unimproved Special Site Features The eastern portion of the site contains a 27,745 square foot, Category 2 Wetland. Statement Addressing Soil Type and Drainage Conditions According to the geotechnical engineering report dated April 2013, provided with this application, the sites soil consist of less than foot of topsoil over loose to very dense silty fine to medium sand with varying amounts of gravel to the depth explored. The surface of the site slopes gradually down from west to east with a natural low in the wetland that encumbers the eastern portion of the site. Proposed Use of the Property and Scope of the Development The proposed use is single family residential with associated public right-of-way, storm drainage facilities (tolbe dedicated and conveyed to the City of Renton bt separate instrument), sanitary sewer and water facilities. Proposed Number,Net Density and Range of Size of the New Lots The Project will create 8 single family residential lots with a net density of 2.5 DU/AC. The lots will range from 7,200 square feet to 7,767 square feet. Access Access to the lots will be by way of an internal road connected to 160th Avenue S.E. that will be dedicated/conveyed to the City of Renton. Proposed Offsite Improvements The 160th Avenue S.E. frontage will be improved to City of Renton standards for pavement width,planting strip, sidewalk, etc. and connections to the existing sanitary and water will be made. Total Estimated Construction Cost and Fair Market Value of the project To be determined upon preliminary short plat approval and engineering approval. Estimate Quantity and Type of Material Involved for proposed excavation During the engineering phase of the proposed development every effort will be mad to balance the cuts and fills with onsite materials. Number, Type and Size of Trees to be Removed 42 conifer trees ranging from 6" to 54 " DBH and 65 deciduous trees ranging from 6" to 32" DBH. Explanation of any Land to be Dedicated to the City 14,313 square feet of right-of--way will be dedicated to the City to provide access to the proposed lots. 11,880 square feet of land will be dedicated to the City for the storm water facilities associated with this development. Any Proposed Job Shacks, Sales Trailers, and/or Model Homes There are no Jon Shacks ors Sales Trailers proposed at this time. A model home will probably be built upon the completion of the construction of this development. Any Proposed Modifications Being Requested for Projects Located Within 100 Feet of a Stream or Wetland The site contains a Category 2 Wetland. The development of the project will be outside of the 50' critical area buffer required,with the exception of a potential underground sanitary sewer main crossing the wetland in order to provide the development with sanitary sewer service. Critical area exemption and mitigation will be applied for separate application if determined necessary during the course of engineering phase of the development.

Earth 2 12-180 ki ndv's Place FOR AGENCY City of Renton SEPA Checklist USE ONLY a. General description of the site (circle one): fiat , rolling, hilly, steep slopes, mountainous. The site is generally flat sloping down from the northwest to the southeast. The site is currently vacant with a dirt driveway/trail extending from the 160th avenue southeast, on the west boundary,through the center of the site. The easterly portion of the site contains a wetland and associated buffer. The site contains numerous deciduous and conifer trees with associated native ground cover vegetation. ' b. What is the steepest slope on the site (approximate percent slope)? According to the field topographic survey,the steepest slope on the site is approximately 10% at an isolated location just west of the center of the site.. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, and muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the USDA Natural Resources Conservation Services Web Soil Survey, the site is Alderwood gravelly sandy loam, 6 to 15 percent slopes d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No surface indications or history of unstable soils in the immediate areawere discovered. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Grading of the site will be necessary to provide a public street and associated storm drainage facilities.The exact quantity of grading is not known at this time, however, it is anticipated that the grading activities would be designed to balance and not require import or export of soil. Grading of the individual home sites will involve the excavation of approximately 150 to 200 CY of cut and/or fill. These issues will:be addressed during the building permit phase. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Some erosion could occur on-site as a result of construction activities; however,temporary erosion and sedimentation control measures to be approved by the City of Renton will be employed to reduce erosion impacts. All construction during the wet season will comply with the surface water design standards in place at the time of preliminary short plat approval. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Due to the preliminary nature of the plans,the exact percentage of impervious surface associated with this project is currently unknown.The subject proposal will not exceed the maximum impervious surface area allowed by the City of Renton 3 12-180 M ndy's Race 1 FOR AGENCY City of Renton SEPA Checklist USE ONLY h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: During construction, the contractor will follow an approved temporary erosion and sedimentation control plan meeting City of Renton standards. Typical measures,which may be employed, include the use of silt fences, straw bales, and temporary:storm drainage features. Hydro seeding exposed soils and cleared areas after construction will also reduce the potential for erosion. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, and industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Construction: Emissions and dust particulates•generated primarily by construction equipment will be produced during the construction phase of this project. The amount of emissions to the air will be minimal and will occur during the actual construction of the development. Long Term Air Quality: Long-term air impacts would be those typically associated with residential land uses. Sources of long-term emissions and odor could include vehicle emissions from increased vehicle use generated by the new residential units and emissions from wood burning fireplaces (if permitted). The additional vehicular emissions in these areas are not anticipated to concentrate and therefore are not anticipated,to create a health hazard to the residents or surrounding areas. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c.

For our use in preparing this report, we have been provided with a drawing titled "l\lindy's Place Conceptual Plan" prepared by DMP Engineering dated November 8, 2012. The &awing provides the planned site layout and stormwater detention facility location. PROJECT DESCRIPTION The development will consist of a total of 8 single-family, residences. The site is essentially flat. We do not anticipate significant Cuts or fills. A stormwater detention facility is planned on the south side of the site with a co+ete retaining wall around the south and northeast side of the pond. The pond will be excavated up to 9 feet below the ground surface. The interior will have 3H:1V side slopes. A 4-foot high retaining wall is planned on the eastern 2/3`d of the pond. The wall will be at the top of a 6-foot high 3H:1V slope. SCOPE The purpose of this study is to explore and characterize the subsurface conditions and present recommendations for site development. Specifically, our scope of services includes the following:_ 1. Review of soils and geologic maps of the area. 2. Explore the subsurface conditions with a trackhoe provided by you. 3. Log the subsurface soil and groundwater conditions. 4. Provide structural fi I and grading recommendations. 5. Provide recommen i ations for foundation support. 6. Provide geotechnical recommendations for use in design of the detention facility. 7. Provide general surface drainage recommendations. 8. Prepare a geotechnical report summarizing our conclusions and recommendations. SITE CONDITIONS Surface Conditions The rectangular shaped project site is about 4.1 acres in size and has maximum dimensions of approximately 595 feet in the east-west direction and 330 feet in the north-south direction. Access to the site is provided by, 160th Avenue SE. The site is bordered-by existing,residential properties to the north and south, with a large wooded area to the east. The west is bordered by 160th Avenue SE. A layout of the site is shown on the Site Plan in Figure 2. The ground surface within the site is generally gently sloping down to the southeast with a total relief within the area to be developed of about 12 to 14 feet. The western portion of the site Robinson Noble, Inc Geotechnical Engineering Report; Mindy's Place Renton, Washington April9, 2013 RN File No. 2605-006A Page 2 has sparse trees and brush. The trees become denser to the east, outside of the planned development area. Geology Most of the Puget Sound Region was affected by past intrusion of continental glaciation. The last period of glaciation, the Vashon Stade of the Fraser Glaciation, ended approximately 14,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon Stade, areas of the Puget Sound region were overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that wre not. Part of a typical glacial sequence within the area of the site includes the following soil deposits from newest to oldest: Artificial Fill (af)— Fill material is often locally placed by human'activities, consistency will depend on the source of the fill. The thickness and expanse of this material will be dependent on extent of fill required to grade land to the desired elevations. Density of the fill will depend on earthwork activities and compaction efforts made during the placement of the materia . Recessional Outwash (Q.vr) —These deposits were derived from the stagnating and receding Vashon glacier and consist of mostly stratified sand and gravel, but include unstratified'ablation and melt-out deposits. Recessional deposits were not compacted by the glacier and are typ'cally not as dense as those that were. Ground moraine deposits (Qgt) —Thin ablation till over lodgment till, deposited by puget glacial lobe. Lodgment till is generally compact, coherent, unsorted, mixture of sand, silt, clay and gravel., commonly termed hardpan. Ablation till similar, but much less compact and coherent. Vashon Till (Qvt)—The VI is a non-sorted mixture of clay, sand, pebbles, cobbles and boulders, all in variable amounts. The till was deposited directly by the ice as it • advanced over and eroded irregular surfaces of previously deposited formations and sediments. The till was well compacted by the advancing glacier and exhibits high strength and stability. Drainage is considered very poor in the till. Advance Outwash (Qva) —The advance outwash typically is a thick section of mostly clean, pebbly sand with increasing amounts of gravel higher in the section. The advance outwash was placed by the advancing glaciers and was overridden and well compacted by the glacier. The geologic units for this area are mapped on the Geologic Map of the Renton Quadrangle, King County, Washington, by D.R. Mullineaux (U.S. Geological Survey, 1965). The site is mapped as being underlain by a deposit of glacial till. Our site explorations encountered glacial till. Robinson Noble, Inc Geotechnical Engineering Report Mindy's Place Renton, Washington I April 9, 2013 RN File No. 2605-006A Page 3 Explorations We explored subsurface conditions at the site on March 18, 2013, by excavating two test pits with a backhoe. The test pits were excavated to depth's of 7.5 and 8.0 feet below the ground surface. The explorations were located in the field by a representative from this firm who also examined the soils and geologic Conditions encountered, and maintained logs of the test pits. The approximate locations of the test pits are shown on the Site Plan in Figure 2. The soils were visually classified in general accordance with the Unified Soil Classification System, a copy of which is presented as Figure 3. The logs of the test pits are presented in Figure 4. Subsurface Conditions A brief description of the conditions encountered in our explorations is included below. For a more detailed description of the oils encountered, review the Test Pit Logs in Figure 4. Our explorations generally enco ntered a surficial layer of topsoil that was less than 1/2 foot in thickness. The topsoil consisted of loose, dark brown silty sand with gravel and roots. • Underlying the topsoil we encountered loose to very dense silty fine to medium sand with varying amounts of gravel. In both test pits, this material extended to the depths explored. Hydrologic Conditions Shallow groundwater seepage was not encountered in the test pits. The dense to very dense till that underlies the site is considered poorly draining. During the wetter times of the year, we expect perched water conditions!!will occur as pockets of water on top of the till layer. Perched water does not represent a regional groundwater "table" within the upper soil horizons. Volumes of perched groundwater vary depending upon the time of year and the upslope recharge conditions. CONCLUSIONS AND RECOMMENDATIONS General It is our opinion that the site is compatible with the planned development. The underlying medium dense to dense glacial tll deposit is capable of supporting the planned structures and pavements. We recommend foundations for the structures extend through any fill, topsoil, loose, or disturbed soils, and bear on the underlying medium dense or dense native glacial till, or on structural fill extending to these soils. Based on our site explorations, we anticipate these soils will generally be encountered at typical footing depths. I The soils likely to be exposed during construction are moisture sensitive and will disturb easily when wet or during wet conditioIns. We recommend that construction take place during the drier summer months, if possible. If construction takes place during the wet season, additional expenses and delays should be expected due to the wet conditions. Additional expenses could include costs for an increased depth of site stripping, export of on-site soil, the import of clean granular soil for fill, and the need, to place a blanket of rock spalls in the access roads and paved areas prior to placing structural fill. Robinson Noble, Inc Geotechnical Engineering-ReportF " _ Mindy`s Place =- a = Renton, Washington t April 9, 2013 _ — .. ` RN File No. 2605-006A Page 4 • Geologic Hazards Landslide Hazard: The site does not have any steep slopes and therefore a landslide hazard does not exist. Erosion Hazard: The erosion hazard criteria used for determination of affected areas includes soil type, slope gradient, vegetation cover, and groundwater conditions. The erosion sensitivity is related to vegetative cover and the specific surface soil types (group classification), which are related to the underlying geologic soil units. We reviewed the Web Soil Survey by the National Cooperative Soil Survey (NCSS) tIo determine the erosion hazard of the on-site soils. The site surface soils were classified using the SCS classification system as Alderwood gravelly sandy loam (Unit 1). The corresponding geologic unit for these soils is till, which is in agreement with the soils encountered in our site explorations. The erosion hazard for the soil.is listed as being slight for the gently sloping condtions at the site. Seismic Hazard: It is our opinion based on our subsurface explorations that the.Soil Profile in accordance with the 2006/2009 and 2012 International Building Code (IBC) is Site Class C with Seismic Design Category D. We used the US Geological Survey program "U.S. Seismic Design Maps Web Application." The design maps summary reports for the 2006/2009 and 2012 IBC are included in this report as Appendix A. Additional seismic considerations include liquefaction potential and amplification of ground motions by soft soil deposits. The liquefaction potential is highest for loose sand with a high groundwater table. The underlying dense till soils are considered to have a very low potential for liquefaction and amplification of ground motion. Site Preparation and Grading The first step of site preparation should be to strip the vegetation, topsoil, or loose soils to expose at least medium dense to dense native soils in pavement and building areas. The excavated material should be rernoved from the site, or stockpiled for later use as landscaping fill. The resulting subgrade shou d be compacted to a firm, non-yielding condition. Areas observed to pump or yield should be repaired prior to placing hard surfaces. The on-site glacial till likely to be exposed during construction is considered moisture sensitive, and the surface will disturb easily when wet. We expect these soils would be difficult, if not impossible, to compact to structural fill specifications in wet weather. We recommend that earthwork be conducted during the drier months. Additional expenses of wet weather or winter construction could include extra excavation and use of imported fill or rock spalls. During wet weather, alternative site preparation methods may be necessary. These methods may include utilizing a smooth-buckettrackhoe to complete site stripping and diverting construction traffic around prepaired subgrades. Disturbance to the prepared subgrade may be minimized by placing a blanket of rock spalls or imported sand and gravel in traffic and roadway areas. Cutoff drains or ditches can also be helpful in reducing grading costs during the wet season. These methods can be!evaluated at the time of construction. Robinson Noble, Inc Geotechnical Engineering Report Mindy's Place Renton, Washington j April 9, 2013 i RN File No. 2605-006A Page 5 Structural Fill General: All fill placed beneath buildings, pavements or other settlement sensitive features should be placed as structural fill! Structural fill, by definition, is placed in accordance with prescribed methods and standards, and is observed by an experienced geotechnical professional or soils technician. Field observation procedures would include the performance of a representative number of in place density tests to document the attainment of the desired degree of relative compaction. Materials: Imported structural fill should consist of a good quality, free-draining granular soil, free of organics and other delete-ious material, and be well graded to a maximum size of about 3 inches. Imported, all-weather structural fill should contain no more than 5 percent fines (soil finer than a Standard U.S. No. 200 sieve), based on that fraction passing the U.S. 3/4-inch sieve. The use of on-site soil as structu al fill will be dependent on moisture content control. Some drying of the native soils may be necessary in order to achieve compaction. During warm, sunny days this could be accom lished by spreading the material in thin lifts and compacting. Some aeration and/or addition of moisture may also be necessary. We expect that compaction of the native soils to structural fil specifications would be difficult, if not impossible, during wet weather. Fill Placement: Following subgrade preparation, placement of the structural fill may proceed. Fill should be placed in 8-to 10-i.ch-thick uniform lifts, and each lift should be spread evenly and be thoroughly compacted prior to placement of subsequent lifts. All structural fill underlying building areas, and within a depth of 2 feet below pavement and sidewalk subgrade, should be compacted to at least 95 percent of.its maximum dry density. Maximum dry density, in this report, refers to that density as determined by the ASTM D1557 compaction test procedure. Fill more than 2 feet beneath sidewalks and pavement subgrades should be compacted to at least 90 percent of the maximum dry density. The moisture content of the soil to be compacted should be within about 2 percent of optimum so that a readily compactable condition exists. It may be necessary to overexcavate and remove wet surficial soils in cases where drying to a compactable cibndition is not feasible. All compaction should be accomplished by equipment of a type and size sufficient to attain the desired degree of compaction. Temporary and Permanent Slopes Temporary cut slope stability is a function of many factors, such as the type and consistency of soils, depth of the cut, surcharge loads adjacent to the excavation, length of time a cut remains open, and the presence of surface or groundwater. It is exceedingly difficult under these variable conditions to estimate astable temporary cut slope geometry. Therefore, it should be the responsibility of the contractor to maintain safe slope configurations, since the contractor is continuously at the job site, ablOo observe the nature and condition of the cut slopes, and able to monitor the subsurface materials and groundwater conditions encountered. i For planning purposes, we recommend that temporary cuts in the near-surface weathered soils be no steeper than 1.5 Horizontal to 1 Vertical (1.5H:1V). Temporary cuts in the dense till Robinson Noble, Inc - Geotechnical Engineering-Keport Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 6 should be no steeper than 1 H:1V. If groundwater seepage is encountered, we would expect that flatter inclinations would be necessary. We recommend that cut slopes ae protected from erosion. Measures taken may include covering cut slopes with plastic sheeting and diverting surface runoff away from the top of cut slopes. We do not recommend (vertical slopes for cuts deeper than 4 feet, if worker access is necessary. We recommend that cut slope heights and inclinations conform to local and WISHA/OSHA standards. Final slope inclinations for granular structural fill and the native soils should be no steeper than 2H:1V. Lightly compacted fills, common fills, or structural fill predominately consisting of fine grained soils should be no steeper than 3H:1V. Common fills are defined as fill material with some organics that are "trackrol ed" into place. They would not meet the compaction specification of structural fill. Fi al slopes should be vegetated and covered with straw or jute netting. The vegetation should e maintained until it is established. Foundations Conventional shallow spread foundations should be founded on at least undisturbed, medium dense to dense soil. If the soil at the planned bottom of footing elevation is not suitable, it should be overexcavated to expose suitable bearing soil. Footings should extend at least 18 inches below the lowest adjacent finished ground surface for frost protection. Minimum foundation widths should conform to IBC requirements. Standing water should not be allowed to accumulate in footing trenches. All loose or disturbed soil should be removed from the foundation excavation prior to placing concrete. For foundations constructed as QQutlined above, we recommend'an allowable design bearing pressure of 3,500 pounds per square foot (psf) be used for the footing design. IBC guidelines should be followed when considering short-term transitory wind or seismic loads. Potential foundation settlement using the recommended allowable bearing pressure is estimated to be less than 1-inch total and ' -inch differential between footings or across a distance of about 30 feet. Higher soil bearing values fray be appropriate with wider footings. These higher values can be determined after a review of a specific design. Lateral Loads The lateral earth pressure actinglon retaining walls is dependent on the nature and densityof the soil behind the wall, the amount of lateral wall movement, which can occur as backfill is placed, and the inclination of the,backfill. Walls that are free to yield at least one-thousandth of the height of the wall are in an "active" condition. Walls restrained from movement by stiffness or bracing are in an "atrest" condition. Active earth pressure and at-rest earth pressure can be calculated based on equivalent fluid density. Equivalent fluid densities for active and at-rest earth pressure of 34 pounds per cubic foot (pcf) and 53 pcf, respectively, may be used for design for a level backslope. These values assume that the on-site soils or imported granular fill are used for backfill, and that the wall backfill is drained. The preceding values do not include the effects of surcharges, such as due to foundation_loads or other surface loads. Surcharge effects should be considered where appropriate. The above drained Robinson Noble, Inc Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 7 active and at-rest values should be increased by a uniform pressure of 6.7H and 21.8H psf, respectively, when considering 2006/2009 IBC seismic conditions. The above drained active and at-rest values should be increased by a uniform pressure of 6.8H and 22.0H psf, respectively, when considering 2012 IBC seismic conditions. H represents the wall height. The above lateral pressures may be resisted by friction at the base of the wall and passive resistance against the foundation. A coefficient of friction of 0.73 may be used to determine the base friction in the native glacial soils. Outside of the pond area, an equivalent fluid density of 240 pcf may be used for passife resistance design. To achieve this value of passive pressure, the foundations should be poured "neat" against the native dense soils, or compacted fill should be used as backfill against the front of the footing, and the soil in front of the wall should extend a horizontal distance at least equal to three times the foundation depth. A factor of safety of 2.0 has been applied to the passive pressure to account for required movements to generate these priessures. The friction coefficient does not include a factor of safety. Lateral resistance within the pond area will be reduced for passive pressure. This is caused by the toe slope inlining down and away from the foundation and by buoyant forces on the soil. See the Detention Pond subsection for lateral loads specific to the pond. All wall backfill should be well corInpacted. Care should be taken to prevent the buildup of excess lateral soil pressures due to overcompaction of the wall backfill. Slabs-On-Grade Slab-on-grade areas should be prepared as recommended in the Site Preparation and Grading subsection. Slabs should be supported on medium dense or better native soils, or on structural fill extending to these sloils. Where moisture control is a concern, we recommend that slabs be underlain by 6 inches of pea gravel for use as a capillary.break. A suitable vapor barrier, such as heavy plastic she'ting, should be placed over the capillary break. An additional 2-inch-thick damp sand blanket can be used to cover the vapor barrier to protect the membrane and to aid in curing the concrete. This will also help prevent cement paste bleeding down into the capillary break through joints or tears in the vapor barrier. The capillary break material should be connected to the footing drains to provide positive drainage. Drainage We recommend that runoff from impervious surfaces, such as roofs, driveway and access roadways, be collected and routed to an appropriate storm water discharge system. The finished ground surface should bell sloped at a gradient of 5 percent minimum for a distance of at least 10 feet away from the buildings, or to an approved method of diverting water from the foundation. Surface water should)be collected by permanent catch basins and drain lines, and be discharged into a storm drain system. We recommend that footing drain be used around all of the structures where moisture control is important. It is good practice to, use footing drains installed at least 1 foot below the planned finished floor slab elevation to provide drainage. Footing drains should consist of 4-inch- Robinson Noble, Inc Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 8 diameter, perforated PVC pipe tat is surrounded by free-draining material, such as pea gravel. Footing drains should discharge into tightlines leading to an appropriate collection and discharge, point. For slabs-on-grade, a drainage path should be provided from the capillary break material to the footing drain system. Roof drains should not be connected to wall or footing drains. Our experience with gently-sloping till sites is that the volume of water collected by residence foundation drains and routed to the stormwater detention system is insignificant when considered in the storm drainage design. We do not expect that water collected from foundation drains will impact the design of the stormwater detention system. Detention Pond A storm water detention pond is planned for the south side of the site, it should be excavated into the underlying native soils. We recommend that any fill berms be constructed of soils having.a maximum permeability of 1 x 10-5 centimeters per second (4 x 10-6 inches/second). The on-site sandy till encountered in our test pit explorations is expected to meet this criterion. We should evaluate any proposed berm fill material prior to construction of the berm. The retaining walls within the pond will be subject to different pressures from those described in the Lateral Loads subsection of this report. For the 'active' condition, the worst case will be when the wall backfill is saturated shortly after the pond has drained. We recommend a wall pressure of 80 pcf during that cor dition. This may be eliminated if gravel backfill behind the wall extends one wall height behind the wall. A fabric should be placed between the gravel and the native soils. The passive pressure in front of the wall should be reduced to 92 pcf. This assumes a minimum 1-foot of flak soil before the slopes. Friction values are the same as previously recommended. Howe'er, buoyant forces need to be used in calculating frictional resistance. The cut slopes of the pond shoul I be no steeper than 3H:1V on the inside of the detention pond and no steeper than 2H:1V above the water table or on the outside portions of the pond berms. Areas with seepage may require a blanket of rock spells or other measures to limit sloughing. Where any berms for the pond are to be constructed, the topsoil and loose soils should be removed down to the competentIglacial till. Areas to receive new fill should-be stripped of unsuitable surface soils and compacted to a firm, non-yielding state prior to placement of the new fill. The excavation should by kept dry to allow the proper placement of structural fill. Structural fill should be placed and compacted as discussed in the Structural Fill subsection of this report. We recommend that the fill in any pond berms be compacted to a minimum of 92 percent of its maximum dry density as determined by the ASTM D1557 compaction test procedure. After each lift of the fill in a berm is compacted to specification, the surface should be scarified to a depth of 2 inches prior to placement of the next lift. The purpose of the scarification is to reduce the-risk of creating preferential seepage paths through-the pond or berms. Robinson Noble, Inc Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 9 It will be important to compact tre face of any pond fill embankments. This should be made explicit to the contractor performing the on-site work. Uncompacted soils on a berm face will be more susceptible to erosion and sloughing. If groundwater seepage is encountered within a cut slope face, a layer of rock splalls may be necessary to minimize erosion of the slope face. The spall layer can be placed at the time of construction, or in the future if sloughing of the slope is observed. Utilities Our explorations indicate that deep dewatering will not be needed to install standard depth utilities. Anticipated groundwater is expected to be handled with pumps in the trenches. We also expect that some groundweter seepage may develop during and following the wetter times of the year. We expect th's seepage to mostly occur in pockets. We do not expect significant volumes of water in these excavations. The soils likely to be exposed in utility trenches after site stripping are considered moisture. sensitive. We recommend that they be considered for trench backfill during the drier portions of the year. Provided these soil are within 2 percent of their optimum moisture content, they should be suitable to meet compaction specifications. During the wet season, it may be difficult to achieve compaction specifications; therefore, soil amendment with kiln dust or cement may be needed to achie V e proper compaction with the on-site materials. Pavement Subgrade The performance of roadway pamement is critically related to the conditions of the underlying subgrade. We recommend that the subgrade soils within the roadways be prepared as described in the Site Preparation and Grading subsection of this report. Prior to placing base material, the subgrade soils should be compacted to a non-yielding state with a vibratory roller compactor and then.proof-rolled with a piece Of heavy construction equipment, such as a fully- loaded dump truck. Any areas w th excessive weaving or flexing should be overexcavated and recompacted or replaced with a structural fill or crushed rock placed and compacted in accordance with recommendations provided in the Structural Fill subsection of this report. CONSTRUCTION OBSERVATION We should be retained to provide observation and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, and to provide recommendations for design changes, should the conditions revealed during the work differ from those anticipated. As part of our services, we would also evaluate whether or riot earthwoqk and foundation installation activities comply with contract plans and specifications.

Y; .11 Above:Aerial photograph of the site. The site, located in the SE quarter of Section 14, Township 23 North, Range 5 East of the W.M., includes an open area covered with weeds and blackberry in the viciniy of the old home site with scattered trees on the west bordering 16oth Avenue SE, and a forested area with cleared trails and disturbed areas on the west. The area is abutted by single family parcels to the north and south, and a new road being constructed along the east. The west side of the site abuts 160 Avenue SE. 2.0 METHODOLOGY Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site on September 11, and October 16, 2012. The site was reviewed using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized bye the City of Renton and the State of Washington for wetland determinations and delineations. The site was also reviewed 1 Th Lakeridge-Mindy's Place Sewall Wetland Consulting, Inc. February 18 2013 Page 3 using the methodology described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), and the Western Mountains, Valleys and Coast region Supplement(Version 2.0) dated June 24, 20110, as required by the US Army Corps of Engineers. Soil colors,were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 199'0). The Washington State Wetlands Identification and Delineation Manual and the Corps of Engineers Wetlands Delineation Manual both requires the use of the three-paramieter approach in identifying and delineating wetlands. A wetland should support a predominance of hydrophytic vegetation, have hydrio soils and display wetland hydrology. To be considered hydrophytic vegetation, over 50% of the dominant species in an area must have an indicator status of facultative (FAC), facultative wetland (FACW), or oblgate wetland (OBL), according to the National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil is "a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part". Anaerobic conditions are indicated in the field by soils with low chromas (2 or less)1 as determined by using the Munsell Soil Color Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally, wetland hydrology is defined by inundation or saturation to the surface for a consecutive period of 12.5% or greater of the growing season. Areas that contain indicators of wetland hydrology between 5%- 12.5% of the growing season may or may not be wetlands depending upon other indicators. Field indicators include visual observation of soil inundation, saturation oxidized rhizospheres, water marks on trees or other fixed objects, drift lines, etc. Under normal circumstances, indicators of all three parameters will be present in wetland areas. 3.0 OBSERVATIONS 3.1 Existing Site Documentation Prior to visiting the site a review of several natural resource inventory maps was conducted. Resources reviewed included the NRCS Soils Survey, the National Wetlands Inventory, and the WDNR Fpars Water Typing Maps. f' Cam' r 1) Lakeridy's PdgeMin lace Sewall Wetland Consulting Inc.ng, February 18 2013 Page 4 3.1.1 MRCS Online S•i1 Mapper Soil Survey The site is mapped as containing Alderwood gravelly sandy loam (Map unit AgC).

The western side of the site has a cleared area where a home once stood, this area has an old driveway and disturbed soils covered with weedy species including blackberry. The site slopes to the east to a low point near the center of the site. Several trails and atv type paths pass through the site, and formerly connected'to trails off-site to the east which are now under development with a road (162nd Avenue SE). Soil pits excavated in the upland areas revealed a high chroma, thy gravelly loam soil. Lakeridge-Mindy's Place Sewall Wetland Consulting Inc. February 18 2013 Page 8 3.2.2 Wetlands The center and eastern side of the site contain a very disturbed forested wetland that also inclu a es a small portion of an ephemeral stream within its western boundaries which is ditched and culverted through the site. This wetland was flagged with flags Al-AA2 and B1-B9 and C.l-C6 and CC1-CC3 (see attached survey DMP Engineering, Inc.). The wetland itself is ve etated with a mix of red alder, salmonberry and lady fern. Soil pits excavated alon the edge of the wetland revealed gravelly loam soil with a color of 10YR 2/2 with redomorphic concentrations.. Soils were found to be dry wit xi within the delineated wetland during our dry season site visit. A small inter.uittent stream enters the wetland from the north. It passes in a ciilvert through approximately 1/2 of the site flowing south, and exits into a itch between flags A7 and B4, before raining off- site to the southeast. The wetland on-site wo ld be classified as PFO1C (palustrine, forested, broad leaved deciduous seasonally flooded), using the US Fish and Wildlife Wetland Classif}cation system (Cowardin et. al 1979). This wetland would be considered a Category 2 wetland under City of Renton Code RMC4-3-050.M1 classifies as a Category 2 wetland due to its relative headwater locat on and minimal disturbance. Typically category 2 wtelands have a 50' b ffer measured from the wetland edge. 3.2.3 Waters ' As previously stated, a small ephemeral stream channel starts to the north of the site in an off-site wetland, drains south into the site, passing through the north part of the wetland in a buried culvert. The streram was dry during our site visit. The culvert dishcarges into a deeply dug ditch before passing off-site into a more natural stream channel. In a previous study we worked on for the Liberty Gardens site to the south and east, this stream was found to go dry in the late spring and was not used by any fish species. Lakeridge-Mindy's Place Sewall Wetland Consulting, Inc. February 18 2013 Page 9 As a result of its ephemeral character and lack of any fish use, this stream best meets the Renton definition of a Class 4 water as described below; iv. Class 4: Class 4 waters are non-salmonid-bearing intermittent waters during years of normal iainfall, and/or mapped on Figure Q4, Renton Water Class Map, as Class 4. Typically Class 4 waters have a 35' buffer, measured from the OHWM of the channel. Since this stream is located within the center of the south part of the wetland on-site, the buffer of the wetland surpasses that of the stream the site. 4.0 Proposed Project The proposed project is the construction of an 8 lot plat on the west side of the site, outside of e wetland, stream and their associated buffers. No impacts to these cri ical areas or their buffers are proposed.

The site is generally rectangular in shape and located in a portion of the SE1/4 of Section 14,Township 23 North, Range 5 East, Willamette Meridian,King County Washington. The parcel number is145750- 0106 and is zoned R-4 by the City of Renton. The property is bordered on three sides by a Large Lot single—family development of varying densities and the plats of Cavalla and Liberty Gardens are currently under iconstruction to the east. The project is accessed by 160th Ave. SE and bordered by 162nd Ave. SE,to the east. The project proposes to develop eight(8) single- family homes and a private road network on the western half of the property and preserve the wetlands and its associated buffers on the eastern portion. There are currently no regulated structures located on the site. The eastern portion of the site is covered with dense trees and shrubs. The west is more sparsely vegetated and includes a cleared area where a home once stood. The site slopes to the east to a low point near the center of the property and generally drains to the south/southeast. A Critical Area report, dated February 18, 2013 was prepared by Sewall Wetland Consultants. This Report identified a heavily modified ephemeral stream,and associated wetland, crossing the eastern third of the property. Site soils have been identified as Alderwood gravely sandy loam by the U.S. Soil Consirvation Service (SCS). i Stormwater will be controlled and treated by a combined detention pond/wetpond to be constructed in the Southern Middle portion of the site. The detention pond will be sized for a Level-2 Flow Control Duration Standard Matching Forested Site Conditions per the City of Renton, 2009 Surface Water Design Manual Amendment.

The site is generally rectangular in shape and located in a portion of the SEA of Section 14, Township 23 North, Range 5 East, Willamette Meridian, King County Washington. The parcel number is 145750-0106 and is zoned is R-4 by the City of Renton The property is bordered on three sides by Large Lot single-family development of varying densities and the plats of Cavalla and Liberty Gardens are currently under construction to the east. The project is accessed by 160th Ave SE and boarded by 162nd Ave SE to the east, on the far side ofthe delineated wetland. The project proposes to develop eight 8) single-family homes and a private road network on the western half of the propertyandpreservethewetlandsanditsassociatedbuffersontheeasternportion. There are currently no regulated structures located on the site. The eastern portion of the site is covered with dense trees and shrubs. The west is more sparsely vegetated and'includes a cleared area where a home once stood. The site slopes to the east to a low point near the,center of the property and generally drains to the south/southeast. A Critical Area report, dated February 18, 2013 was prepared by Sewall Wetland Consultants and identified a heavily modified ephemeral stream, and associated wetland, crossing the eastern third of the property. Site soils have been identified as Alderwood gravelly sandy loam by the U.S. Soil Conservation Service SCS) On-Site Drainage Analysis The site is located within the Lower Cedar Basin of the Cedar River. It slopes to the east to a low point near the center of the property where it generally drains to the south / southeast. The western half of the site is covered with scattered trees while areas of heavy Trees and brush are concentrated in the eastern portion. The average slope across the developable portion of the site from west to east is approximately 5 percent.A review of the site indicates no history of unstable soils. A more detailed description of the on-site condition can be found in the Critical Area report, dated February 18, 2013 was prepared by Sewall Wetland Consultants. Upstream Drainage Analysis As shown in Exhibit B, the site receives surfaceace water runoff from approximately 10 acres of off-site property to the north but less then one acre of up-stream run-off impacts the proposed development area. The upstream basin is broken into two components. The easterly element consists of woods, brush and the recently completed plat of Liberty Grove, while the limited drainage impacting the western side of the property is derived from a few large lot single-family homes. Storm water from said basin enters the proposed development area via sheet flow along the northern property line. The ephemeral stream and its associated wetland will be protected within a sensitive area tract and separated from the development area by an appropriate buffer. Downstream Drainage System Description The project site is within the Lower Cedar Basin of the Cedar River. Site runoff presently discharges into an earth-lined ephemeral stream channel near the southeast corner of the property and travels across the undeveloped portion of 162nd Ave SE onto the southwest corner of the recently approved plat of Liberty Gardens (See exhibit B). This crossing was altered and replanted in 2012 as part of the adjacent Cavalla development. Water then continues to flow south and southeast before curving back towards the eastern side of thIe162nd Avenue SE ROW, where it is collected in an 18' DI pipe and conveyed under the Inewly constructed sewer access road within the 162nd St. ROW and into the revised storm water pond at the SE 1144th intersection. From the detention facility, water is conveyed across SE 144th Street via an 18" CMP culvert. Water then travels west within 18" conveyance facilities along the southern side of SE 144th Street. The system components are shown in Exhibit C, and are itemized in the Off-site Analysis Drainage System Table (Exhibit I). This portion of the downstream drainage system was documented extensively in the June 15, 2007 Level 3 report by Ed. McCarthy as part of the previous Threadgill, Cavalla and Liberty Garden plat review. This report is on file with the city of Renton. The two downstream crossings of 162nd Ave SE, south of the project, were improved as part of the adjacent Cavalla development and are detailed in the 162nd Ave SE Sewer and Water Plan and Profile. Barghausen Eng) Future Site Conditions The Applicant proposes to develop 8 Single-Family residential lots and associated private road network on the project site. The remaining area would be designated as Native Growth Protection easement and storm water facility. The City of Renton requires that storm water facilities be designed and constructed in accordance with the guidelines of the 2009 King County Surface Water Design Manual as amended by the City of Renton. The new storm water facility will be constructed on the southern edge of the development area, and will be sized per the Level 2 Flow Control criteria. The proposed facility will discharge to the ephemeral stream at the south / southeast property corner. Up-stream flows impacting the northwest corner of the property will be intercepted at the north property line and directed/dispersed to the ephemeral stream channel. No off-site work is proposed. TASK 2: Resource Review The following is a description of each of the resources reviewed in preparation of this Downstream Analysis: 1. Critical Drainage Area Map The project site drains Ito the southeast and is located within the Cedar River Basin. 2.Flood Plain/Floodway GFEMA) Maps The site is not within a;100-year floodplain. Refer to Exhibit D 3. Offsite Analysis Reports As part of our research, we have reviewed the Level 3 Downstream Drainage Analysis for the Evendell Plat. Evendell Plat is located in the southwest corner of the intersection of SE 136th Street and 160th Avenue SE. We also reviewed the Level I Off-site Analyses for Liberty Grove and Liberty Grove Contiguous. The two plats are located in the northwest and southeast corners of the previously mentioned intersection. The three projects were required to upgrade downstream facilities s part of their approval. These three projects form the immediate up-stream portion of the study basin. A Level 3 Downstream Drainage Analysis was also prepared by Edward McCarthy, P.E. in 2007 at the request of King County DDES in conjunction with the review of the Liberty Gardens, Threadgill, and Cavalla Plats. The report provides an assessment of the conveyance system along SE 144th Street downstream from the approved projects and Mindy's Place. In addition, we have referenced the 162nd Ave SE Sewer and Water Plan and Profiles created by Barghausen Eng. as part of the Cavalla development. These improvements have recently been installed and are fully functional. 4.Sensitive Areas Information Copies of the Sensitive Areas information obtained from the King County and the . City of Renton were integrated into the Critical areas study prepared by Sewall Wetland Consulting, dated February 18, 2013. The report identifies a large wetland complex on the eastern half of the site (Exhibit G & H.) The wetland and ephemeral stream were originally identified as part of the Liberty Gardens development review. No portion of the highly modified sensitive area will be impacted by the proposed development. 0 5. SWM Division Drainage Investigation Information A map showing the location of the different drainage complaints within the area is included in this report as Exhibit G. There are no reported drainage complaints within 1/ 4 mile downstream. Discharge from the Mindy's Place site will not adversely affect any associated property. 6. King County Soils Survey Maps The soils underlying the site are underlain with Alderwood gravelly sandy loam AgC). Alderwood soils are not considered "hydric" according to the referenced Wetland Study. A copy of the relevant page from the King County Soils Survey Map is included as Exhibit H. TASK 3: Field Inspection The conveyance facilities downstream from the proposed detention facility were inspected. The following was performed as part of the inspection. 1.Investigation of Reported or Observed Problems During Resource Review Please see Exhibits G and I and also Task 2 of this report. 2.Location of Existing/Potential Constrictions or Lack of Capacity in the Existing Drainage System See Exhibit I. 3.Identify Existing/Potential Flooding Problems There were no existing or potential problems identified. 4.Identify Existing/Potential Overtopping, Scouring, Bank Sloughing, or Sedimentation See Exhibits I 5.Identification of Significant Destruction of Aquatic Habitat or Organisms At the time of the site visit, there where no signs of aquatic habitat or organism destruction. 6. Collect Qualitative Data on Land Use, Impervious Surfaces, Topography and Soil Types Qualitative data has been collected from previous field visits. This information is included within this report. 7.Collect Information on Pipe Sizes, Channel Characteristics and Drainage Structures See Exhibits C and I. 8. Verify Tributary Basins Delineated in Task 1 At the time of the site visit, the tributary basins described in Task 1 were verified as being accurate. AP 9. Contact Neighboring Property Owners in the Area There were no neighbors available during our site visit. 10. Note the Date and Weather Conditions at the Time of the Site Visit The site and downstream system were visited on February 28, 2013. Light rain. I i TASK 4: Drainage System Description and Problem Description 1.Drainage System Descriptions: As previously stated, runoff from the site and upstream areas leaves the site at the south property line and travels southeast across private property. The individual drainage components are listed in Exhibit I, and are shown in Exhibit C. Once the storm water is captured in the new 162nd Ave SE crossing, the remaining downstream conveyance facilities are within public ROW. 2.Problems: There are currently no;reported off-site problems identified in King County records. The adjacent;Cavalla development has improved/modified the two downstream crossingsi of 162nd Ave SE as well as the detention facility at the SE 144th St. intersection. All other existing facilities within the 144th Street ROW are functioning without issue. I ' TASK 5: Mitigation of Existing or Potential Problems This development involves the creation of eight single-family residential lots. Access roads and roadway improvements will also be part of the development. Storm water facilities will be provided, and will be sized per the guidelines of the adopted Surface Water Design Manual. The new detention facility will be constructed in the south portion of the development ara, and will be sized per the Level 2 Flow Control criteria. A water quality facility, sized per the Basic Water Quality Menu, will be constructed below the detention facility. The proposed facility will discharge to the ephemeral stream at the southeast property corner. With implementation of the recommended conveyance, detention and water quality standards, and recent downstream improvements installed as part of the Cavalla development, this project should not pose significant negative impacts to the downstream drainage course.

The site slopes east to a low point near the center of the property where it generally drains to the south/southeast. The western half of the site is covered with scattered trees while area of heavy trees and brush are concentrated in the eastern portion. The average slope across the developable portion of the site from west to east is approximately 5 percent. A more detailed description of the onsite conditions can be found in toe Critical Area report, dated February 18,2013 prepared by Sewall Wetland Consultants, (See Section VI of this T.I.R.). This Report identified a heavily modified ephemeral stream,and associated wetland, crossing the eastern third of the property. DEVELOPED SITE HYDROLOGY(PART B) The applicant proposes to develop 8 single-family residential lots with associated roadway and storm drainage pond located with the westerly side of the site. The easterly side of the project will be placed in a NGPE Tract. The developable portion of the site will be approximately 2.08 acres. Storm water runoff from homes,landscaped areas, and roadway will be collected in a series of storm drainage pipes and conveyed to the combination detention/wet-pond facility.The pond will discharge storm water runoff to the out pipe located with the NGPE buffer. The water quality and quantity control facility(Pond)located in the middle and southern portion of the site,is sized for a Level-2 Flow Control Duration Standard Matching Forested Site Conditions per the City of Renton,2009 Surface Water Design Manual Amendment(page 1-35). Please see the calculations within this section showing how the facility has met the standards for both flow duration and peak flow control. Since the lots are small and since the permeability of the site soils will not meet the standards for infiltration,the Reduced Impervious Surface Credit will.be used as a BMP for this site(total of 49.5%). Each new lot will be limited in the amount of square footage of impervious surface. See the Reduced Impervious Surface Credit calculations found below. Lot 1 =7,200sf x 49.5%=3,564sf Lot 2=7,200sf x 49.5%=3,564sf Lot 3 =7,304sf x 49.5%=3,615sf Lot 4=7,767sf x 49.5%=3,844sf Lot 5 =7,200sf x 49.5%=3,564sf Lot 6=7,733sf x 49.5%=3,827sf Lot 7= 7,200sf x 49.5%=3,564sf Lot 8= 7,200sf x 49.5%=3,564sf 0 PERFORMANCERFRMANCE STANDARDS(PART C) The project site is required to provide a stormwater facility meeting the Level-2 Flow Control Duration Standard Matching Forested Site Conditions per the City of Renton,2009 Surface Water Design Manual Amendment(page 1-35) and the Basic Water Quality Treatment standards. FLOW CONTROL SYSTEM(PART D) It is proposed to provide a combined detention pond/wetpond to mitigate for the increase in runoff due to development. In addition,the.Reduced Impervious Surface Credit was used as a BMP for this site. The detention portion of the combined stormwater facility is required to have a storage volume of approximately 22,128 cu.ft,while the available storage volume is 25,864 cu.ft. The proposed pond details are included in the plan set. i WATER QUALITY SYSTEM(PART E) The sizing calculations for the proposed wetpond are included in page 25. The bottom portion of the stormwater facility will be utilized for water quality. The required storage volume is approximately 3,000 cu.ft.,while the available storage volume is 3,739 cu.ft. The proposed wetpond details are included in the plan set. EMERGENCY OVERFLOW SPILLWAY In the event of total failure of the control structure,and emergency overflow spillway is provided to convey the 100-yr, 15 min. developed peak flow rate(See page 22). In the event that water goes over the spillway,water will be discharged through the 50-foot forested buffer and then to the wetland where it will be safely conveyed to the downstream drainage corridor. 1 • 1 , I ' I api 2,.iiReni.',.if,,,::;.:;.,.;:.•.,,,,,Nh' .:,,:., .,„ lk city Amendments to the King Count... x Efl1B007.1,7099116.0th fru. 15_,...,Benton,...:,......eur el 1 13 j * I- e., .4...,..-'rentonwa.govjuploadedf des/Government/P'N/U 'Sod,,TILITIES/Sud e Watei.."City.4nendrnents to the King County Surf ace Water Design A lanual.pd( mapquest P tiEMostf BookmarksVisited@,)Getting Started . 1 at,This PDF document might not be displayed correctly. pen With Different Viewer x r.yiare-1. •-'''- • -4 13a-g6 402 r../' ,.: :','.ei.!...r..,'' .:t'zi.''..":'-'-.7:1::,:i-f-4,5r, ',f.'',:ge's.-,--:'''.:'::: ;L:.;,.:.-"f.,:•'','t.',,'-'''.'': _.' .-.

FLOW CONTROL DURATION STANDARD AREAS The flow control duration standard requires runoff from urban developments to be detained and released at a rate that matches the flow duration of predeveloped rates over the range of flows extending from'/a of the 2-year up to the 50-year flow. Also match developed peak discharge rates to predeveloped peak discharge rates for the 2-and 10=year return periods. Flow duration specifies the cumulative amount of time that various flows are equaled or exceeded during a long-term simulation using historical rainfall. The target flow duration may be the"historic"(i.e.,fully forested condition)or in specific situations it may be the existing site or`;`pre-project"condition as described below. The Flow Control Applications Map shows the areas where the"forested"and"existing"conditions are allowed. Forested land cover—Runoff from the developed site will be controlled and released at a rate that matches the flow duration for a forested("historic")land cover. The"historic"land cover is the default standard required by the technical requirements of the NPDES permit. The standard is applicable to those areas draining to streams that have erodible channels where runoff from urban areas has the potential to destabilize the channel. Existing land cover—Runoff from the developed site will be controlled and released at a rate that matches the flow duration for the site conditions existing before the development. These are areas that have been developed for years and drain to stream channels that have become stabilized to a new hydrologic regime. Ecology has proposed that the existing land cover can be used in basins that have had at least 40%total impervious surface area for the 20 years preceding Ecology's adoption of the 2005 Stormwater Management Manual for Western Washington(called the 40/20 rule)and the stream channels receiving the runoff are considered stable from the standpoint of excessive erosion or sedimentation. In developing the"40/20 rule"for highly urbanized basins,Ecology conducted a preliminary analysis and produced maps that identify those areas that may meet the criteria. Portions of Renton were included in the initial maps prepared by Ecology. These maps have been adjusted to better represent the areas that were 40%impervious in 19,85 as well as drainage basin divides within the City. Flow control facilities designed to the"40/20 rule"will only have to mitigate for the added impervious surface. As a result,these flow control facilities will be smaller than those required to be designed to match runoff from a fully forested site. Minimum Required Pei formance Facilities in Flow Control Duration Standard Areas must comply with the following flow control performance standard and assumptions unless modified by offsite analysis per Core Requirement#2(see Table 1.2.3.A,p. 1-31): 1 Flow Control Duration Standard Matching Forested Site Conditions:Match developed discharge durations to predeveloped durations for the range of predeveloped discharge rates from 50%of the 2- year peak flow up to the full 50-year peak flow. Also match developed peak discharge rates to predeveloped peak discharge rates for the 2-and 10-year return periods. Assume forested(historic) site conditions as the predeveloped condition. Flow Control Duration Standard Matching Existing Site Conditions:Match developed discharge durations to predeveloped durations for the range of predeveloped discharge rates from 50%of the 2-year peak flow up to the full 50-year peak flow. Also match developed peak discharge rates to predeveloped peak discharge rates for the 2-and 10-year return periods. Assume existing site conditions as the predeveloped condition. Effectiveness in AddressingDownstreamDrainageProblems While the Flow Control Duration Standard flow control standard assuming historic site conditions provides a reasonable level of protection for preventing most development-induced problems,it does not necessarily prevent increases in existing site conditions 100-year peak flows that can aggravate severe flooding problems as described in Core Requirement#2,nor does it necessarily prevent aggravation of all severe erosion problems. Consequently,if one or more of these problems are identified through offsite analysis per Core Requirement#2,,additional onsite flow control and/or 2009 Surface Water Design Manual Amendment City of Renton 1-35 DMP, INC.JOB Mit..tDy5 PLA-c,E Engineering - Surveying - Land Planning SHEET NO.

The site, located in they SE quarter of Section 14, Township 23 North, Range 5 East of the W.M., includes an open area covered with weeds and. blackberry in the vicinity of the old home site with scattered trees on the west bordering 16oth Avenue SE, and a forested area with cleared trails and disturbed areas on the west. The area is abutted by single family parcels to the north and south, and a new road being constructed along the east. The west side of the site abuts 160th Avenue SE. 2.0 METHODOLOGY Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site on September 11, and October 16, 2012. The site was reviewed using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized by the City of Renton and the State of Washington for wetland determinations and delineations. The site was also reviewed Lakeridge-Mindy's Place Sewall Wetland Consulting, Inc. February 18 2013 Page 3 using the methodology, described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), and the Western Mountains, Valleys and Coast region Supplement (Version 2.0) dated June 24, 2010, as required by the US Army Corps of Engineers. Soil colors were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 1990). The Washington State Wetlands Identification and Delineation Manual and the Corps of Engineers' Wetlands Delineation Manual both requires the use of the three-parameter approach in identifying and delineating wetlands. A wetland should support a predominance of hydrophytic vegetation, have hydric soils and display wetland hydrology. To be considered hydrophytic vegetation, over 50% of the dominant species in an area must have an indicator status of facultative (FAC), facultative wetland (FACW), or obligate wetland (OBL), according to the National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil isi"a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part". Anaerobic conditions are indicated in the field by soils with low chromas (2 or less), as determined by using the Munsell Soil Color Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally, wetland hydrology is defined by inundation or saturation to the surface for a consecutive period of 12.5% or greater of the growing season. Areas that contain indicators of wetland hydrology between 5%- 12.5% of the growing season may or may not be wetlands depending upon other indicators.I Field indicators include visual observation of soil inundation, saturation, oxidized rhizospheres, water marks on trees or other fixed objects, drift lines, etc. Under noiinal circumstances, indicators of all three parameters will be present in wetland areas. 3.0 OBSERVATIONS 3.1 Existing Site Documentation Prior to visiting the site a review of several natural resource inventory maps was conducted. Resources reviewed included the NRCS Soils Survey, the National Wetlands Inventory, and the WDNR Fpars Water Typing Maps. Lakeridge-ivIindy's Place. Sewall Wetland Consulting, Inc. February 18 2013 Page 4 3.1.1 NRCS Online Soil Mapper Soil Survey The site is mapped as containing Alderwood gravelly sandy loam (Map unit AgC). Alderwood;soils are not considered "hydric" or wetland soils according to the publication Hydric Soils of the United States (USDA NTCHS Pub No.1491, 1991). 1 r 4Y --.2 - .`::tl t fw.'' + s. 1"tKti r.z`:"V t4' `4 i T f t* S . atc4.1 40 # ems _w 41 x""• 'n 5 ` l ti '3 t .

':, fi ;¢4 1 Above: City of Renton Stream Map 3.2 Field Observations 3.2.1 Uplands As previously described, the site is an undeveloped property with open disturbed area on the west and forested area to the east. The western side of the site has a cleared area where a home once stood, this area has an old driveway and disturbed soils covered with weedy species including blackberry. The site slopes to the east to a low point near the 1 center of the site. Several trails and atv type paths pass through the site, and formerly connected to trails off-site to the east which are now under development with a road (162nd Avenue SE). Soil pits excavated in the upland areas revealed a high chroma, dry gravelly loam soil. Lakeridge-lvlindy's Place Sewall Wetland Consulting, Inc. February 18 2013 Page 8 3.2.2 Wetlands The center and eastern side of the site contain a very disturbed forested wetland that also includes a small portion of an ephemeral stream within its western boundaries which is ditched and culverted through the site. This wetland was flagged with flags Al-AA2 and Bl-B9 and Cl-C6 and CC1-CC3 (see attached survey DMP Engineering, Inc.). The wetland itself is vegetated with a mix of red alder, salmonberry and lady fern. Soil pits excavated along the edge of the wetland revealed gravelly loam soil with a color of 10YR 2/2 with redoximoiphic concentrations. Soils were found to be dry within the delineated wetland during our dry season site visit. A small intermittent stream enters the wetland from the north. It passes in a culvert through approximately 1/2 of the site flowing south, and exits into a ditch between flags A7 and B4, before raining off- site to the southeast. The wetland on-site would be classified as PFO1C (palustrine, forested, broad leaved deciduous, seasonally flooded), using the US Fish and Wildlife Wetland Classification system (Cowardin et. al 1979). This wetland would be considered a Category 2 wetland under City of Renton Code RMC4-3-050.M1 classifies as a Category 2 wetland due to its relative headwater location and minimal disturbance. Typically category 2 wtelands have a 50' buffer measured from the wetland edge. 3.2.3 Waters As previously stated, a small ephemeral stream channel starts to the north of the site in an off-site wetland, drains south into the site, passing through the north part of the wetland in a buried culvert. The streram was dry during our site visit. The culvert dishcarges into a deeply dug ditch before passing off-site into a more natural stream channel. In a previous study we worked on for the Liberty Gardens site to the south and east, this stream was found to go dry in the late spring and was not used by any fish species. Lakeridge-lvfindy's Place Sewall Wetland Consulting, Inc. February 18 2013 Page 9 As a result of its ephemeral character and lack of any fish use, this stream best meets the Renton definition of a Class 4 water as described below; iv. Class 4: Class 4 waters are non-salmonid-bearing intermittent waters during years of normal rainfall, and/or mapped on Figure Q4, Renton Water Class Map, as Class 4. Typically Class 4 waters have a 35' buffer, measured from the OHWM of the channel. Since this stream is located within the center of the south part of the wetland on-site, the buffer of the wetland surpasses that of the stream the site. 4.0 Proposed Project The proposed project is the construction of an 8 lot plat on the west side of the site, outside of the wetland, stream and their associated buffers. No impacts to these critical areas or their buffers are proposed.

The site is located at the intersection of 1601h Avenue SE and SE 141 st Street, as shown on the Vicinity Map in Figure 1. You have requested that we complete this report to evaluate subsurface conditions and provide recommendations for site development. For our use in preparing this report, we have been provided with a drawing titled "Mindy's Place Conceptual'Plan" prepared by DMP Engineering dated November 8, 2012. The drawing provides the planned site layout and stormwater detention facility location. PROJECT DESCRIPTION j The development will consist of a total of 8 single-family residences. The site is essentially flat. We do not anticipate significant cuts or fills. A stormwater detention facility is planned on the south side of the site with a concrete retaining wall around the south and northeast side of the pond. The pond will be excavated up to 9 feet below the ground surface. The interior will have 3H:1V side slopes. A 4-foot high retaining wall is planned on the eastern 2/3td of the pond. The wall will be at the top of a 6-foot high 3H:1V slope. SCOPE The purpose of this study is to explore and characterize the subsurface conditions and present recommendations for site development. Specifically, our scope of services includes the following: li 1 . Review of soils and'geologic maps of the area. 2. Explore the subsurface conditions with a trackhoe provided by you. 3. Log the subsurface!soil and groundwater conditions. 4. Provide structural fill and grading recommendations. 5. Provide recommendations for foundation support. 6.

SITE CONDITIONS Surface Conditions The rectangular shaped project site is about 4.1 acres in size and has maximum dimensions of approximately 595 feet in the east-west direction and 330 feet in the north-south direction. Access to the site is provided by 160th Avenue SE. The site is bordered by existing residential properties to the north and south, with a large wooded area to the east. The west is bordered by 160th Avenue SSE.-A layout of the site is shown on_the Site Plan in Figure 2. The ground surface.within the site is generallygently,sloping down to the:southeast with a total relief within'the area to be developed of about'12 to 14 feet. The western portion of the site Noble,Robinson=Robinson N , vy Geotechnical Engineering Report' Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 2 has sparse trees and brush. The trees become denser to the east, outside of the planned development area. Geology Most of the Puget Sound Region was affected by past intrusion of continental glaciation. The last period Of glaciation, the Vashon Stade of the Fraser Glaciation, ended approximately 14,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon,Stade, areas of the Puget Sound region were overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that were not. Part of a typical glacial sequence within the area of the site includes the following,soil deposits from newest to oldest: Artificial Fill (af) — Fill material is often locally placed by human-activities, consistency will depend on the source of the fill. The thickness and expanse of this material will be dependent on extent of fill required to grade land to the desired elevations. Density of the fill will depend on earthwork activities and compaction efforts made during the placement of the material. Recessional Outwash (Qvr) —These deposits were derived from the stagnating and receding Vashon glacier and consist of mostly stratified sand and gravel, but include unstratified ablation and melt-out deposits. Recessional deposits were not compacted by the glacier and are typically not as dense as those that were. Ground moraine deposits (Qgt) —Thin ablation till over lodgment till, deposited by puget glacial lobe. Lodgment till is generally compact, coherent, unsorted, mixture of sand, silt, clay and gravel: commonly termed hardpan. Ablation till similar, but much less compact and coherent. Vashon Till (Qvt)—The till is a non-sorted mixture of clay, sand, pebbles, cobbles and boulders, all in variable amounts. The till was deposited directly by the ice as it advanced over and erode irregular surfaces of previously deposited formations and sediments. The till was well compacted by the advancing glacier and exhibits high strength and stability. Drainage is considered very poor in the till. Advance Outwash (Qva) —The advance outwash typically is a thick section of mostly clean, pebbly sand with increasing amounts of gravel higher in the section. The advance outwash was placed by the advancing glaciers and was overridden and well compacted by the glacier. The geologic units for this area are mapped on the Geologic Map of the Renton Quadrangle, King County, Washington,.byD.R•.-Mullineaux (U.S. Geological Survey, .1965). The site is mapped as being_underlain-by adepc3sit of glacial till. Our site explorations_.encountered glacial till. in NOFi'obi son le -lnc Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 3 Explorations We explored subsurface conditions at the site on March 18, 2013, by excavating two test pits with a backhoe. The test pits were excavated to depths of 7.5 and 8.0 feet below the ground surface. The explorations were located in the field by a representative from this firm who also examined the soils and geologic conditions encountered, and maintained logs of the test pits. The approximate locations of the test pits are shown on the Site Plan in Figure 2. The soils were visually classified in-general accordance with the Unified Soil Classification System, a copy of which is presented as Figure 3. The logs of the test pits are presented in Figure 4. Subsurface Conditions A brief description of the conditions encountered in our explorations is included below. For a more detailed description of the soils encountered, review the Test Pit Logs in Figure 4. Our explorations generally encountered a surficial layer of topsoil that was less than 1/2 foot in thickness. The topsoil consisted of loose, dark brown silty sand with gravel and roots. Underlying the topsoil we encountered loose to very dense silty fine to medium sand with varying amounts of gravel. In both test pits, this material extended to the depths explored. Hydrologic Conditions Shallow groundwater seepage was not encountered in the test pits. The dense to very dense till that underlies the site is considered poorly draining. During the wetter times of the year, we expect perched water conditions:will occur as pockets of water on top of the till layer. Perched water does not represent a regional groundwater "table" within the upper soil horizons. Volumes of perched groundwater vary depending upon the time of year and the upslope recharge conditions. CONCLUSIONS AND RECOMMENDATIONS General It is our opinion that the site is compatible with the planned development. The underlying medium dense to dense glacial till deposit is capable of supporting the planned structures and pavements. We recommend foundations for the structures extend through any fill, topsoil, loose, or disturbed soils, and bear on the underlying medium dense or dense native glacial till, or on structural fill extending to these soils. Based on our site explorations, we anticipate these soils will generally be encountered at typical footing depths. The soils likely to be exposed during construction are moisture sensitive and will disturb easily when wet or during wet conditions. We recommend that construction take place during the drier summer months, if possible. If construction takes place during the wet season, additional expenses and delays should be expected due to the wet conditions. Additional expenses could include costs for.:an increased depth of site stripping,_:export of on-site''soil, the import of clean granular soil for fill, and the need to place a blanket oflock spalls in the access roads and paved areas prior.to:placing structural fill. y` bible- Inc • Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 • RN File No. 2605-006A Page 4 Geologic Hazards Landslide Hazard: The site does not have any steep slopes and therefore a landslide hazard does not exist. Erosion Hazard: The erosion hazard criteria used for determination of affected areas includes soil type, slope gradient, vegetation cover, and groundwater conditions. The erosion sensitivity is related to vegetative cover and'the specific surface soil types (group classification), which are related to the underlying geologic soil units. We reviewed the Web Soil Survey by the National Cooperative Soil Survey (NCSS) to determine the erosion hazard of the on-site soils. The site surface soils were classified using the SCS classification system as Alderwood gravelly sandy loam (Unit 1). The corresponding geologic unit for these soils is till, which is in agreement with the soils encountered in our site explorations. The erosion hazard for the soil is listed as being slight for the gently sloping conditions at the site. Seismic Hazard: It is our opinion based on our subsurface explorations that the Soil Profile in accordance with the 2006/2009 and 2012 International Building Code (IBC) is Site Class C with Seismic Design Category D. We used the US Geological Survey program "U.S. Seismic Design Maps Web Application." The design maps summary reports for the 2006/2009 and 2012 IBC are included in this report as Appendix A. Additional seismic considerations include liquefaction potential and amplification of ground motions by soft soil deposits. The liquefaction potential is highest for loose sand with a high groundwater table. The underlying dense till soils are considered to have a very low potential for liquefaction and amplification of ground motion. Site Preparation and Grading The first step of site preparation should be to strip the vegetation, topsoil, or loose soils to expose at least medium dense to dense native soils in pavement and building areas. The excavated material should be removed from the site, or stockpiled for later use as-landscaping fill. The resulting subgrade should be compacted to a firm, non-yielding condition. Areas observed to pump or yield should be repaired prior to placing hard surfaces. The on-site glacial till likely to be exposed during construction is considered moisture sensitive, and the surface will disturb easily when wet. We expect these soils would be difficult, if not impossible, to compact to structural fill specifications in wet weather. We recommend that earthwork be conducted during the drier months. Additional expenses of wet weather or winter construction could include.extra excavation and use of imported fill or rock spells. During wet weather, alternative site preparation methods may be necessary. These methods may include utilizing a smooth-bucket trackhoe to complete site stripping and diverting construction traffic around prepared._subgrades. Disturbance to the prepared subgrade may be minimized by placing a blanket of rock'spalls or imported sand and gravel in traffic and roadway areas. Cutoff_drains'or ditchesacan also:behelpful in reducing grading costs during the wet season.=aThese methods;canbeevaluatedat::the.time-of-construction:- nonNobleInc Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 5 Structural Fill General: All fill placed beneath buildings, pavements or other settlement sensitive features should be placed as structural fill: Structural fill, by definition, is placed in accordance with prescribed methods and standards, and is observed by an experienced geotechnical professional or soils technician. Field observation procedures would include the performance of a representative number of in-place density tests to document the attainment of the desired degree of relative compaction. Materials: Imported structural fill should consist of a good quality, free-draining granular soil, free of organics and other deleterious material, and be well graded to a maximum size of about 3 inches. Imported, all-weather structural fill should contain no more than 5 percent fines (soil finer than a Standard U.S. No. 200 sieve), based on that fraction passing the U.S. 3/4-inch sieve. The use of on-site soil as structural fill will be dependent on moisture content control. Some drying of the native soils may be necessary in order to achieve compaction. During warm, sunny days this could be accomplished by spreading the material in thin lifts and compacting. Some aeration and/or addition of moisture may also be necessary. We expect that compaction of the native soils to structural fill specifications would be difficult, if not impossible, during wet weather. Fill Placement: Following subgrade preparation, placement of the structural fill may proceed. Fill should be placed in 8-to 10-inch-thick uniform lifts, and each lift should be spread evenly and be thoroughly compacted prior to placement of subsequent lifts. All structural fill underlying building areas, and within a depth of 2 feet below pavement and sidewalk subgrade, should be compacted to at least 95 percent of its maximum dry density. Maximum.dry density, in this report, refers to that density as determined by the ASTM D1557 compaction test procedure. Fill more than 2 feet beneath sidewalks and pavement subgrades should be compacted to at least 90 percent of the maximum dry density. The moisture content of the soil to be compacted should be within about 2 percent of optimum so that a readily compactable condition exists. It may be necessary to overexcavate and remove wet surficial soils in cases where drying to a compactable condition is not feasible. All compaction should be accomplished by equipment of a type and size sufficient to attain the desired degree of compaction. Temporary and Permanent Slopes Temporary cut slope stability is a function of many factors, such as the type and consistency of soils, depth of the cut, surcharge.loads adjacent to the excavation, length of time a.cut remains open, and the presence of surface or groundwater. It is exceedingly difficult under these variable conditions to estimate a stable temporary cut slope geometry. Therefore, it should be the responsibility of the contractor to maintain_safe slope configurations, since the contractor is continuously at the job site'able to_observe the,nature and condition of the._cut slopes,=and able monitor the subsurface:materials and groundwater,conditions encountered:-,- . w_ - planning purposes, we recommend that temporary cuts in the near-surface weathered soils no steeper than 1.5 Horizontal-to 1_Vertical (1.5H:1 V):;_Temporary cuts in the•dense till _- R'ob nsonFNob e`1ncr Geotechnical Engineering Report Mindy's Place Renton, Washington April 9, 2013 RN File No. 2605-006A Page 6 should be no steeper than 1 H:1 V. If groundwater seepage is encountered, we would expect that flatter inclinations would be necessary. We recommend that cut slopes be protected from erosion. Measures taken may include covering cut slopes with plastic sheeting and diverting surface runoff away from the top of cut slopes. We do not recommend vertical slopes for cuts deeper than 4 feet, if worker access is necessary. We recommend thatcut slope heights and inclinations conform to local and WISHA/OSHA standards. Final slope inclinations for granular structural fill and the native soils should be no steeper than 2H:1V. Lightly compacted fills, common fills, or structural fill predominately consisting of fine grained soils should be no steeper than 3H:1V. Common fills are defined as fill material with some organics that are "trackrolled" into place. They would not meet the compaction specification of structural fill. Final slopes should be vegetated and covered with straw or jute netting. The vegetation should be maintained until it is established. Foundations Conventional shallow spread foundations should be founded on at least undisturbed, medium dense to dense soil. If the soil at the planned bottom of footing elevation is not suitable, it should be overexcavated to expose suitable bearing soil. Footings should extend at least 18 inches below the lowest adjacent finished ground surface for frost protection. Minimum foundation widths should conform to IBC requirements. Standing water should not be allowed to accumulate in footing trenches. All loose or disturbed soil should be removed from the foundation excavation prior to placing concrete. For foundations constructed as outlined above, we recommend an allowable design bearing pressure of 3,500 pounds per square foot (psf) be used for the footing design. IBC guidelines should be followed when considering short-term transitory wind or seismic loads. Potential foundation settlement using the recommended allowable bearing pressure is estimated to be less than 1-inch total and ' -inch differential between footings or across a distance of about 30 feet. Higher soil bearing values May be appropriate with wider footings. These higher values can be determined after a review:of a specific design. Lateral Loads The lateral earth pressure actingon retaining walls is dependent on the nature and density of the soil behind the wall, the amount of lateral wall movement, which can occur as backfill is placed, and the inclination of the backfill. Walls that are free to yield at least one-thousandth of the height of the wall are in an "active" condition. Walls restrained from movement by stiffness or bracing are in an "at-rest" condition. Active earth pressure and at-rest earth pressure-can.be_calculated based on equivalent fluid density. Equivalent fluid densities for ._ active and at4est-earth pressure-of 34 pounds per cubic foot (pcf) and 53 pcf,.Jespectivelji, may be used for design fora level backslope.

The above drained active and at-rest values should be increased by a uniform pressure of 6.8H and 22.0H psf, respectively, when considering 2012 IBC seismic conditions. H represents the wall height. The above lateral pressures may be resisted by friction at the base of the wall and passive resistance against the foundation. A coefficient of friction of 0.73 may be used to determine the base friction in the native glacial soils. Outside of the pond area, an equivalent fluid density of 240 pcf may be used for passive resistance design. To achieve this value of passive pressure, the foundations should be poured "neat" against the native dense soils, or compacted fill should be used as'backfill against the front of the footing, and the soil in front of the wall should extend a horizontal distance at least equal to three times the foundation depth. A factor of safety of 2.0 has been applied to the passive pressure to account for required movements to generate these pressures. The friction coefficient does not include a factor of safety. I I Lateral resistance within the pond area will be reduced for passive pressure. This is caused by the toe slope inlining down and away from the foundation and by buoyant forces on the soil. See the Detention Pond subsection for lateral loads specific to the pond. All wall backfill should be well compacted. Care should be taken to prevent the buildup of excess lateral soil pressures due to overcompaction of the wall backfill. Slabs-On-Grade Slab-on-grade areas should be prepared as recommended in the Site Preparation and Grading subsection. Slabs should be supported on medium dense or better native soils, or on structural fill extending to these soils. Where moisture control is a concern, we recommend that slabs be underlain by 6 inches of pea gravel for use as a capillary break. A suitable vapor barrier, such as heavy plastic sheeting, should be placed over the capillary break. An additional 2-inch-thick damp sand blanket can be used to cover the vapor barrier to protect the membrane and to aid in curing the concrete. .This will also help prevent cement paste bleeding down into the capillary break through joints or tears in the vapor barrier. The capillary break material should be connected to the footing drains to provide positive drainage. Drainage We recommend that runoff from impervious surfaces, such as roofs, driveway and access roadways, be collected and routed to an appropriate storm water discharge system. The finished ground surface should be sloped at a gradient of 5 percent minimum for a distance of at least 10 feet away from the buildings, or to an approved method of diverting water from the foundation: Surface water-should be collected by permanent catch basins and drain lines, and be discharged into-a-storm drain system.

For slabs-on-grade, a drainage path should be provided from the capillary break material to the footing drain system. Roof drains should not be connected to wall or footing drains. Our experience with gently-sloping till sites is that the volume of water collected by residence foundation drains and routed to the stormwater detention system is insignificant when considered in the storm drainage design. We do not expect that water collected from foundation drains will impact the'design of the stormwater detention system. Detention Pond A storm water detention pond is planned for the south side of the site, it should be excavated into the underlying native soils. We recommend that any fill berms be constructed of soils having a maximum permeability of 1 x 10-5 centimeters per second (4 x 10-6 inches/second). The on-site sandy till encountered in our test pit explorations is expected to meet this criterion. We should evaluate any proposed berm fill material prior to construction of the berm: The retaining walls within the pond will be subject to different pressures from those described in the Lateral Loads subsection of this report. For the 'active' condition, the worst case will be when the wall backfill is saturated shortly after the pond has drained. We recommend a wall . pressure of 80 pcf during that condition. This may be eliminated if gravel backfill behind the wall extends one wall height behind the wall. A fabric should be placed between the gravel and the native soils. The passive pressure in front of the wall should be reduced to 92 pcf. This assumes a minimum 1-foot of flat soil before the slopes. Friction values are the same as previously recommended. However, buoyant forces need to be used in calculating frictional resistance. The cut slopes of the pond should be no steeper than 3H:1 V on the inside of the detention pond and no steeper than 2H:1V above the water table or on the outside portions of the pond berms. Areas with seepage may;require a blanket of rock spalls or other measures to limit sloughing. Where any berms for the pond are to be constructed, the topsoil and loose soils should be removed down to the competent glacial till. Areas to receive new fill should.be stripped of unsuitable surface soils and compacted to a firm, non-yielding state prior to placement of the new fill. The excavation should be kept dry to allow the proper placement of structural fill. Structural fill should be placed and compacted as discussed in the'Structural Fill subsection of this report. We recommend that the fill in any pond berms be compacted"to a'minimum of 92. . percent of its maximum dry density as determined by the ASTM 01557 compaction test procedure.

This should be made explicit to the contractor performing the on-site work. Uncompacted soils on a berm face will be more susceptible to erosion and sloughing. If groundwater seepage is encountered within a cut slope face, a layer of rock spells may be necessary to minimize erosion of the slope face. The spell layer can be placed at the time of construction, or in the future if sloughing of the slope is observed. Utilities Our explorations indicate that deep dewatering will not be needed to install standard depth utilities. Anticipated groundwater is expected to be handled with pumps in the trenches. We also expect that some groundwater seepage may develop during and following the wetter times of the year. We expect this seepage to mostly occur in pockets. We do not expect significant volumes of water in these excavations. The soils likely to be exposed in utility trenches after site stripping are considered moisture sensitive. We recommend that they be considered for trench backfill during the drier portions of the year. Provided these soils are within 2 percent of their optimum moisture content, they should be suitable to meet compaction specifications. During the wet season, it may be difficult to achieve compaction specifications; therefore, soil amendment with kiln dust or cement may be needed to achieve proper compaction with the on-site materials. Pavement Subgrade The performance of roadway pavement is critically related to the conditions of the underlying subgrade. We recommend that the subgrade soils within the roadways be prepared as described in the Site Preparation and Grading subsection of this report. Prior to placing base material, the subgrade soils should be compacted to a non-yielding state with a vibratory roller compactor and then proof-rolled with a piece of heavy construction equipment, such as a fully- loaded dump truck. Any areas with excessive weaving or flexing should be overexcavated and recompacted or replaced with a structural fill or crushed rock placed and compacted in accordance with recommendations,provided in the Structural Fill subsection of this report. CONSTRUCTION OBSERVATION We should be retained to provide'observation and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, and to provide recommendations for design changes, should the conditions revealed during the work differ from those anticipated. As part of our services, we would also evaluate whether or not earthwork and foundation installation activities comply with contract plans and specifications.

Jerry explains that the storm water has increased,and he feels that the new developments to the north are the cause. He acknowledges that the water has flowed onto his property but he claims that it would stop during the summer and he was able to work on the property. Now he says the property is continually wet due to'the storm water making his property non-usable. Jerry invited Dave Petrie who owns the 10 acres to the east of Jerry's property to the meeting. Dave claims that in 1974 the west ditch line of 160th AVE SE was diverted to the east ditch through a 12" cross tile just north of Jerry's , property (the pipe was upgraded to a 24" CPEP by KC in 2004/5) causing all the storm water to flow through Derry's property . He is in the'middle of developing his property and he claims that this diversion has caused problems rto the development proceedings of his property. Both Jerry and Dave want the storm water flows from the north of Jerry's property to continue south oh 160th AVE SE to SE 144t".ST thus eliminating the storm water entering Jerry's property and impacting the development of Dave's property. DOT is involved with this issue as well (see attached email) and have determined that the cross tile will not be removed_to direct the flows past Mr. Smith's property. ' Both Mr. Smith and Petrie have.been informed that if they want to redirect the stormwater they must work with DDES.

Per RMC 4-2-11OA the minimum lot size is 8,000 square feet with footnote 11. Footnote 11 allows for the reduction of the minimum lot size to 7,200 square feet. 1 ue to the large sensitive area and lot configuration this short plat has a minimum lot size of 7,200 square feet to achieve the maximum density possible as permitted by RMC 4-2-11OD 11. This short plat provides a full width Local Residential Access street section up to a reduced hammerhead. The reduced hammerhead maintains the required pavement section eliminating the un-n Icessary planter strip and sidewalk. This hammerhead terminates at a large wetland/sensitive area and has no possibility of future extension. This reduction is necessary to achieve maximum density and has been supported by city staff as evidenced by the attached email and Tentative Short Plat. city of RentonPlanningDivision JUN -'7 2013 W E©1ElVLSD Page 1 of 4 Sean Reinicke From: Rocale Timmons [RTimmons@Rentonwa.gov] Sent: Friday, January 04, 2013 8:08 AM To:Sean Reinicke' Subject: RE: Mindy's place tentative short plat You were actually on my ToDo list for today. Yes he did have an opportunity to look at it yesterday and he is supportive of the modification. You will still have to formally apply (when you come in to subdivide) and we will need to solicit comments internally and 4om the public. If there is opposition to the modification we will need to revisit planning's support based on the integrity of the comments. Please let me know if you have any additional questions. Rocale T.

And he told me he was okay with the reduced hammerhead turn-around however, he was not inclined to approve the street modification to allow improvements on just one side of the road as there is adequate room to reduce the lot size to provide for the required street improvements.

Henning; waynejonesjr@agmail.com Subject: Mindy's;place tentative short plat Good morning Rocale, Attached is a pdf of the revised layout per our phone conversation yesterday. The private easement has been eliminated.A public road terminating in hammer head is being proposed. We ha're provided a sidewalk on the north side of the proposed road that terminates at the turnaround with 20' of pavement width as required by fire. Per RMC 4-2-110D, footnotes 11 and 12 this layout will also not need to go through any lot clustering "provisions/requirements" if the Reviewing Official will allow the reductions described in the footnotes. The critical area buffers and inaccessible area for development impact the developable are to an extent that the reductions would be needed to achieve the maximum density permitted with the use of these footnotes. Please let me know your take on this lay out and what can be done satisfy any of the City's concerns. Thanks D.M.P.,Inc.

Jerry explains that the storm water has increased and he feels that the new developments to the north are the cause. He acknowledges that the water has flowed onto his property but he claims that it would stop during the summer and he was able to work on the property. Now he says the property is continually wet due to the storm water making his property non-usable. Jerry invited Dave Petrie who owns the 10 acres to the east of Jerry's property to the meeting. Dave claims that in 1974 the west ditch line of 160th AVE SE was diverted to the east ditch through a 12" cross tile just north of Jerry's property (the pipe was upgraded to a 24" CPEP by KC in 2004/5) causing all the storm water to flow through Jerry's property . He is in the middle of developing his property and he claims that this diversion has caused problems to the development proceedings of his property. Both Jerry and Dave want the storm water flows from the north of Jerry's property to continue south on 160th AVE SE to SE 144th ST thus eliminating the storm water entering Jerry's property and impacting the development of Dave's property. DOT is involved with this issue as well (see attached email) and have determined that the cross tile will not be removed to direct the flows past Mr. Smith's property. Both Mr. Smith and Petrie have been informed that if they want to redirect the stormwater they must work with DDES.

I.,t ::\- 1 poi'$ . il Mindy's Place Justification for Modification This short plat is zoned R-4. Per RMC 4-2-110A the minimum lot size is 8,000 square feet with footnote 11. Footnote 11 allows for the reduction of the minimum lot size to 7,200 square feet. Due to the large sensitive area and lot configuration this short plat has a minimum lot size of 7,200 square feet to achieve the maximum density possible as permitted by RMC 4-2-110D 11. This short plat provides a full width Local Residential Access street section up to a reduced hammerhead. The reduced hammerhead maintains the required pavement section eliminating the un-necessary planter strip and sidewalk. This hammerhead terminates at a large wetland/sensitive area and has no possibility of future extension. This reduction is necessary to achieve maximum density and has been supported by city staff as evidenced by the attached email and Tentative Short Plat. tfenton JUN -- 7 2013 Page 1 of 4 r Sean Reinicke From: Rocale Timmons [RTimmons@Rentonwa.gov] Sent: Friday, January 04, 2013 8:08 AM To:Sean Reinicke' Subject: RE: Mindy's place tentative short plat You were actually on my ToDo list for today. Yes he did have an opportunity to look at it yesterday and he is supportive of the modification. You will still have to formally apply (when you come in to subdivide) and we will need to solicit comments internally and from the public. If there is opposition to the modification we will need to revisit planning's support based on the integrity of the comments. Please let me know if you have any additional questions. Rocale T.

Lot size, width, and depth may be reduced by the Reviewing Official when, due to lot configuration or access, four(4) dwelling units per net acre cannot be achieved. The reduction shall be the minimum needed to allow four(4) dwelling units per net acre and shall be limited to the following minimum dimensions: Lot size—seven thousand two hundred (7,200) sq. ft. Lot width —sixty feet (60'). Lot depth —seventy feet(70'). 12. When lot size is reduced for the purpose of achieving maximum density, setbacks may also be reduced by the Reviewing Official. Setback reductions shall be limited to the following: Front—twenty feet (20'). Side yard along a street—fifteen feet (15') primary structure, twenty feet(20') attached garage with access from the side yard. D.M.P., Inc.

And he told me he was okay with the reduced hammerhead turn-around however, he was not inclined to approve the street modification to allow improvements on just one side of the road as there is adequate room to reduce the lot size to provide for the required street improvements. Please feel free to contact me if you have any further questions.

Henning; waynejonesjr@gmail.com Subject: Mindy's place tentative short plat Good morning Rocale, Attached is a pdf of the revised layout per our phone conversation yesterday. The private easement has been eliminated. A public road terminating in hammer head is being proposed. We have provided a sidewalk on the north side of the proposed road that terminates at the turnaround with 20' of pavement width as required by fire. Per RMC 4-2-110D, footnotes 11 and 12 this layout will also not need to go through any lot clustering "provisions/requirements" if the Reviewing Official will allow the reductions described in the footnotes. The critical area buffers and inaccessible area for development impact the developable are to an extent that the reductions would be needed to achieve the maximum density permitted with the use of these footnotes. Please let me know your take on this lay out and what can be done satisfy any of the City's concerns. Thanks D.M.P., Inc.
