I understand that Lozier Homes has purchased the property from JayMarc Development and that you have requested revisions on behalfofLozierHomes. Request These requested·revisions are summarized as follows: 1. Relocate Drainage Tract A from the intersection of Field Ave NE and NE 2•• Place to the interior of the site. 2. Reconfigure Lots 25-28 and 34 -42 as a result of the relocation of Tract A. 3. Revise Drainage Tract B by adding a retaining wall along the north and west perimeter of T~act B, and revise proposed planting plan within Tract n. 4. Revise fence design along stream buffer on east edge of Lots 48 and 49 to replace split rail fence with black vinyl chain link fence. 5. Revisions to the rightCof-way dedication requirement along NE 2•• Street. 6. Revisions to access easement and property boundary for Lots 45, 48 and 49. 7. Revise treeretention plan to replace trees on al:1 basis. Analysis 1. Re.locate Drainage Tract A from the intersection of Field Ave NE and NE 2•• Place to the interior of the site. The proposed drainage tract would be relocated from the intersection of Field Ave NE and NE 2°• Place to the interior of the site where Lots 34 and 39 were previously proposed. The applicant contends that the relocation of the drainage pond would allow the pond to be at the lowest topographic part of the site on the interior to both improve drainage functions and the aesthetic quality of the development. The approved plat indicates that the drainage tract was proposed to occupy approximately 19,670 square feet of area. As requested in the current letter, Tract A would be 20,217 square feet in ----'----10_5_5 -So_u_th_G_r-ad_y_W-.a-y---R-en-to_n_, W_as_h_in-gt-on-9-80_5_7 ______ ~ @ This paper contains 50% recycled material, 30% post consumer AHEAD OF THE CURVE June 13, 2007 Page2 size. The change in area results in an increase in the size of the tract by 2. 7%. The drainage tract would'relocate to the interior of the plat, rather than being located on a comer where Field Ave NE and NE z•d Place intersect. In the approved plat, the drainage pond was accessible from either Field Ave NE, NE 2"d Place or from NE 2"d Street via a joint driveway and utility access easement. The proposal is for access via two separate 15-foot wide public drainage easements; one from NE200 Place and the other from NE 2"d Street. Recommendation: Approve relocation of the drainage pond subject to the condition that a landscape plan providing extensive plantings and a 6-foot high wood fence be installed prior to recording of the final plat. The landscape plan would be required to be designed by a licensed Landscape Architect andprovide trees, shrubs and groundcOver that would result in an opaque screen within three years of installation. The final landscape plan and fence detail is subject to the review and approval of the Development Services Project Manager. 2. Reconfigure Lots 2$ -28 and Lots 34 -42. The relocation of the storm drainage pond results in the reconfiguration of Lots 25 through 28 and Lots 34 through 42. Lot sizes would change as shoivn below: . . . . · Lot Number .

June 13, 2007 Page 3 On the approved plat drawing, Lots 34 and 39 do not have street frontage, while Lots 35, 36, 37, 38, 40, 41 and 42 do have frontage on the streets. The request for revision would allow each of · lots 34 through 42 to have street frontage, which is determined to be a preferable platting pattern. All of the lots would meet minimum size and dimensional requirements for lot width and depth. Lots 38 and 42 would be corner lots and would meet the required 60-foot width. The remaining lots would be interior lots and would meet the minimum 50 foot width requirement of the R-8 Zoning designation. Recommendation: Approve the reconfiguration of Lots 25 -28 and 34 -42 as proposed. 3. a) Revise Drainage Tract B by adding a retaining wall along the north and west perimeter of Tract B; and, b) revise proposedlandscaping planting plan with'in Tract B. The applicant proposes to install a retaining wall;~n the nor\!) and west perimeter of Tract B where the rear of Lots 43, 44, a11;d 49 abut Tract B in order to allow yards to be leveled and to eliminate a steep 2: I slope. A fence that is 6-feet in height would be installed at the top of the wall on the tract perimeter. · Changes are also proposed to landscaping within l4e,Drainage Tract B arna .. The applicant proposes to replace Silver Lind<in,trees (Tilia T~mei)foeya},ahd Austrian Black Pine (Pinus nigra),. Incense Cedar (Calocedrµs de,;urtens ), Rockrose. (tistl!~'J,urpur,,ea},)3ig 0j3luestem {Andropogon gerardii) with one tree and shrub.s. Recommendation: a) Approve the installation ofthe retaining wall and fence subject to the condition that the Development Services Project Manager provides rev\ew ,md approval authority regarding the fence detail. b) Deny the request to eliminate trees and shrubs surrounding Drainage Tract B. The applicant shall install plantings as indicated on Sheet L-2 of the Landscape Plan prepared for the project (reference name Lindberg Plat, dated 5/3/2006) subject to some minor substitutions may be allowed per the review and approval of the Development Services Project Manager. The · landscape plans must be submitted for review and plantings installed prior to recording of the plat. 4. Revise fence design along stream buffer on east edge ofLots.48 and 49 to replace split rail fence with black vinyl chain link fence. The applicant proposes to add a retaining wall with a 4-foot high black vinyl chain-link fence (with wetland signage) at the top of the retaining wall and at the edge of the 25-foot Native Growth Protection Easement, along the east edge of Lots 48 and 49. The black vinyl chain-link fence would prevent humans and pets from encroaching into the streambuffer area from the rear portion of Lots. 48 and 49. Recommendation: Approve as proposed. June 13, 2007 Page4 5. Revisions to the right-of-way dedication requirement along NE 2•d Street. The applicant proposes to shift the 12-foot and 15-foot right-of-way dedication requirement along NE 2•d Street, in order to better line up with each other and the right-of-way. A "jog" is proposed at Lot 42, where the 12-foot dedication will change to 15-feet. · Recommendation: Approve as proposed. 6, Revisions to acc.ess easement and property boundary for Lots 45, 48 and 49. The applicant proposes to modify the 20-foot wide access ea.semen! (previously located on Lots · 45, 48, and 49) such that it will be located on Lots 45 and 49 only, and will provide access to Lots 48 and 49. In addition, the southern boundary of L_ot 48 was shifted north. Recommendation: Approve as proposed. 7. Revise the tree retention plan to replace trees on a 1:1 basis. The Hearing Examiner requir~d that a revised tree retention plifo be Submitted that retained 25% of the trees identified forretertiion. The plan was to include m!"lsureSproposed to protect the • retained trees, The applicanlw!IS required to pr~v(,d!:-justification ror replacement of trees that . cou_ld not be retained.

In addition,. 58 additional ornl)metrlal trees are proposed. · Staff was able to find 16 of the 19 trees shown to be retained on the tree plan. No detail for. protection of the trees has been provided. In addition, trees previously slated for retention in the approved preliminary plat, especially in the vicinity of Lots 21 through 24 are now shown for removal. No justification is proposed for removal of these trees. They are not affected by the relocation of the storm pond. Recommendation: Applicant shall revise their tree clearing plan to retain trees shown at the confluence of the common property lines (central}to Lots 21, 22, 23 and 24. This represents 8 trees: 8-inch fir, JO-inch fir, 12-inch fir, 12-inch fir, 18-inch fir, 24-inch fir, and 42-inch fir (see . attached exhibit). In addition, the two 36-inch deciduous twin trees shown as located between Lots l7 and 18 must be retained, unless determined to be unhealthy or dangerous by an arborist (see Exhibit B).

RMC Sections 4-8-120A, B, and D list information required on grading, roadway improvements, and utility drawings. However, they do not specifically note that proposed tree protection measures shall be depicted on each of these plan sheets. Additionally, while Section 4-4-130H requires a developer to take measures to protect trees to be preserved from construction damage, it does not specify how this is to be done. JUSTIFICATION: In order to avoid field problems with contractors removing and/or damaging trees that were required to be protected, visually and DECISION: physically significant barriers need to be installed to protect branches and root systems of trees to be preserved. In order for City inspectors to ensure that those trees intended to be preserved are not cut or damaged in the site development phase, protective measures need to. be identified on each construction plan sheet. Also, a procedure needs to be established to verify installation of all required protection measures prior to issuance of a construction, utility, or building pennit. • Temporary Fencing Required: Six f<lot high temporary chain link fencing (see attached plan detail) shall be required to completely enclose all trees to be preserved. :Jbe· fei,.ice, set upon concrete blocks and not into the topsoil, shall be located no closer than the drip line of any tree to be preserved or along the perimetel"of a stand of retained trees. The Development Services Division.must verify in the field that fencing has been installed prior to construction, utility, or building permit issuance. Temporary Signage During Con~tPtiction: A placard must be placed on the fence of each individual tree to be retained. In the case of stands of trees, placards are required at 50' minimum intervals. The placard should read: "PROTECTED TREES, Any damage to tree is subject to a fine and C,ty of Renton tree replacement requirements". DIVISION HEAD APPROVAL: APPEAL PROCESS: Dl08.doc Protective Measures identified/depicted on Plan Sheets: Each tree to be protected and the temporary chain link fencing shall be depicted on each of the following plan sheets: 1. Grading Plan 2. Utility Plans (sewer, water and storm drainage) 3. Building Permit Site Plan (for all projects, including individual platted lots, that have undergone land use/green folder permit review) Form Updates and Docketing: These requirements and procedures shall be added to the application instructions for each type of pennit and this determination shall be docketed for inclusion in the 2007 code update process. I , -----'--'A'---"--'--'/ eJL_C__/ tu~· ttt;-'---1._; _ DATE: c)'3/J6/U7 I I To appeal this determination, a written appeal--accompanied by the required $75.00 filing fee--must be filed with the City's Hearing Examiner (1055 South Grady Way, Renton, WA 98057) no more than 14 days from the date of this decision.

The Magnussen Plat application bas been modified due to changes in property ownership and a subsequent re-evaluation of project goals. The following details the nature and extent of each modification and describes the rationale and design intent. The goal of the redesign is to achieve a plat that functions more effectively, better protects the critical areas within the site, and is more aesthetically pleasing. Requested modifications are categorized below by impacted areas within the plat. Please note that the lot numbers refer to the revised lot numbering system on the amended Preliminary Plat sheet ( copy enclosed). 1. Tract A (Drainage} -Relocation • Changes o Tract A (Drainage Pond) was relocated from the intersection of Field Ave NE and NE 2•• Place to the interior. Changes to landscaping were made only within the drainage pond. • Rationale and Design Intent o The drainage basin and flow amounts will remain the same after the change. o The drainage pond was relocated from its' street frontage location to the lowest topographic part of the site on the interior to both improve drainage functions and the aesthetic quality of the development. Visual impacts to residents and passers-by on the street will be reduced, thus lessening the need for extensive screening and landscaping on the interior of the pond and along its perimeter. o Screening & Landscaping: • A 6-ft tall solid wood fence will screen Tract A and extend along the north, south, and eastern property boundaries along the rear yards of the adjacent lots ( see pond fence detail on Sheet 12). The westernmost boundary of Tract A currently consists of an existing fence and a very established dense screen of tall trees and vegetation. The existing fence and vegetation negate the need for additional screening. These elements will remain in place and form the western property boundary of Tract A. • Backyard landscaping (trees, shrubs, and groundcover) is proposed as external screening of Tract A for those lots that abut the fence and will occur as part of the house construction. Mog11u11e11 Plc,t 5.23.2007 Poge2of4 Since the pond will be inundated and graded at a 2: 1 slope, the fence will provide sufficient screening from the adjacent properties; and it is not necessary or viable to propose extensive interior landscaping. This tract will be vegetated with grass, clover, and appropriate hydrophilic, low growing, vegetation. 2. Tract A (Drainage) -Lot Reconfiguration • Changes o Lot layout immediately adjacent to Tract A was revised to accommodate the relocation. Impacted lots include Lots 25-28 and Lots 34-42. • Rationale and Design Intent o In addition to relocating lots along the perimeter of Tract A, Lots 34, 35, 36, and 37 were reoriented from a stacked east to west configuration to a side by side north to south configuration. This change results in the lots fronting onto NE 2•• St, thus eliminating the need for a joint driveway/access road. These lots now front onto the public roadway. A 15- ft drainage and access easement is now located over new Lot 36. 3. Tract B (Drainage) • Changes o 1) Lots 43, 44, & 49: A retaining wall was added on the north and west perimeter of Tract B where the rear of Lots 43, 44, and 49 abut the Tract. A 6-ft high solid wood fence will be placed at the top of the wall on the tract perimeter. Changes to landscaping were made only within the drainage pond. o 2) Lot 43: Southeastern property line of Lot 43 was reconfigured to follow the edge of the new rockery and the contour of the access road. • Rationale and Design Intent o 1) Lots 43, 44, & 49: • The original 6-ft high wood fence around Tract B was located 3-ft east and south of the property lines (within the tract) and within an area graded at a steep 2: I slope. The former configuration would have resulted in unusable yards and unsafe conditions for residents of the homes due to the steep slopes. The modification will create a safe, level, and more easily maintainable yard. Furthermore, the placement of the fence at 3-feet inside the Tract boundary would have resulted in confusion about where the rear yards of the adjoining lots were located. Such a condition leaves the door open for future claims for adverse possession. • Backyard landscaping (trees, shrubs, and groundcover) is proposed as external screening of Tract B for those lots that abut the fence and will occur as part of the house construction. • Since the pond will be inundated and graded at a 2: I slope, the fence will provide sufficient screening from the adjacent properties; and, it is not necessary or viable to propose extensive interior landscaping. This tract will be vegetated with grass, clover, and appropriate hydrophilic, low growing, vegetation. 13 i J3ME I.

Stream Buffer Protection • Changes o A retaining wall with a 4-ft tall black vinyl chain link fence (with wetland signage) at the top of the wall was added at the edge of the 25-ft NGPE buffer along the eastern edge of Lots 48 and 49. The retaining wall and fence replace the original slope and split rail fence. • Rationale and Design Intent o The original approval included a 2: I slope leading down to the stream with a split rail fence to delineate the buffer boundary. As the NGPE is part of the lots, the potential for encroachment and stream impacts is high. The split rail fence and slope would have resulted in less than ideal conditions for residents and increased runoff and erosion to the stream. Additionally, it would be insufficient in preventing encroachment. The new proposal will serve several purposes. First, the retaining wall and fence will create a safer and more usable yard and provide more visual access to the buffer area. Second, the black vinyl chain link fence will address safety needs and more effectively protect the buffer from human and animal (i.e. pet) impacts. 5. Right of Way {ROW) Requirements on NE 2•d St • Changes o The 12-ft and 15-ft ROW dedication requirement locations along NE 2•• St (adjacent to the southern property boundaries of Lots 34-37) have been shifted. • Rationale and Design Intent o Lots 34-37 have been standardized to better line up with each other and with the ROW. As such, Lot 42 is where the ROW 'jog" will change from 12-ft to 15-ft. The road improvements and geometry will remain unchanged. 6, Access Easement and Property Boundary Shift • Changes o The 20-ft wide access easement (previously located on Lots 45, 48, and 49) has been modified and is now located only on Lots 45 and 49. Lot 48 southern property boundary was shifted north. • Rationale and Design Intent o A small portion of the access easement was previously located on Lot 48, which resulted in an offset of the southern property boundaries of Lots 46 and 48. To rectify this incongruity, 137 J3ME t. Suite 3 lssoquoh. WA 98027 e 425.313.1078 425.313.1077 Magnu11e11 Plat 5 23 2007 Poge4of4 the southern property boundary of Lot 48 was moved slightly north. As such, the easement will now only be located on Lots 45 and 49. o The easement portion on Lot 49 (adjacent to Lot 48) was extended from 15-ft to 20-ft to improve driveway access to Lot 48. 7. Tree Retention • Changes o Several trees originally designated for retention have been removed due to the relocation of Tract A and subsequent pond construction. In order to meet the 25% tree retention requirement, these designated trees will be replaced as necessary at a 1: 1 ratio in order to comply with the City of Renton Development Services Division "Interpretation/Policy Decision" (RMC Section 4-4-130H4 and 7; Performance Standards for Land Development/Building Permits -Tree Preservation; Tree/Ground Cover Retention). Thank you in advance for your time and consideration. We look forward to working with you for the remainder of our project. Best regards, 1YI (j1J)[l1,'1/AchcJs Morgan Nit:hois Planner Encl.

Specifically, you asked me to accomplish three tasks, rather than a comprehensive review. The first task was to evaluate the current status of the off-site wetland, labeled as Wetland A on the engineering drawings. Second, you asked me to determine the jurisdictional status of the swale draining Wetland A. Third, you asked me to determine how section 4.4.050.L.5.c.iv applies to the buffer of the stream along the eastern edge of the project. Findings As shown on the Preliminary Plat Map for the project, Wetland A extends onto the project site by a few feet. The on-site wetland area is indicated on the map with flag numbers WF-2, WF-3 and WF-4. During my site visit the off-site portion of the wetland had been cleared and was in the process of being filled with a crushed concrete aggregate, presumably as a base for future development and allegedly as authorized by the City of Renton. MSJ'lw.(f flee+ The small on-site portion is outside the silt fence/grading limits and likely will not be filled. This area retains all three wetland parameters. However, since the majority of the wetland was permitted to be filled as it was below the size threshold for regulation, this remnant area would similarly not be regulated by the City of Renton. The swale exiting the remaining wetland remnant is actually a piped system that appears to have been in place for a long time and is not a recently constructed feature. There is no evidence of a natural stream channel formed by erosion or hydraulic sorting of sediment. At some time in the past, the swale may have been a stream cham1el or wetland swale, or both. Remnant soils and a few patches of remnant hydrophytic vegetation persist. No wetland hydrology was noted. It appears that past disturbance has eliminated any regulated critical areas that may have once existed along this corridor. Code section 4.4.050.L.5.c.iv details how stream buffers may be approved for reduction in width. Subsection 1 asks if the land is extensively vegetated with native species, including trees and shrubs, and has less than five percent non-native invasive species cover. My evaluation of this 750 Sixth Street South , Kirkland, WA 98033 p 425.822.5242 / 425.827.8136 watershedco.com V. Kinas! June 15'\ 2006 Page 2 of2 area discovered that the buffer is extensively vegetated, but that a few patches of non-native species exist. Specifically these include the following: I) Patches of Himalayan blackberry vines at both the northern and southern on-site portion of the buffer. 2) A small area of ivy is found beneath the forest canopy at the northern edge of the buffer, just south of the blackberry patch. 3) A moderately sized patch of bishop's hat (Epimedium spp.) was noted in the middle section of the buffer. Bishop's hat is an aggressive escaped ornamental groundcover that prefers wet stream edges under shade. The ivy and bishop's hat likely comprise more than 5% of the groundcover within the buffer. However, the three invasive, non-native weeds noted above likely do not comprise 5% or more of the aggregate groundcover, mid-story and canopy cover within the buffer. Subsection (5)(c) of this section also requires that the project include a buffer enhancement plan. Such a plan should include provisions to remove these invasive weeds and their root systems. The weeded areas should then be replanted with appropriate species. This concludes my review of this project. Please call with any questions.

Development Services Recommendation: Approve subject to conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on October 3, 2006. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area; the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the October 10, 2006 hearing. The legal record is recorded on CD. The hearing opened on Tuesday, October I 0, 2006, at approximately 9:34 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No. 2: Preliminary Plat Map application, proof of posting, proof of publication and other documentation oertinent to this r,.,,ucst.

The site is located east of Duvall Avenue NE, north of NE 200 Street. The site is zoned R-8 and the Comprehensive Plan designation is Residential Single-Family. The site consists of seven parcels for a total of 8.3 7 acres, there are five existing homes with accessory structures, all of them will be removed. The proposal for 49 lots arrives at a net density of 7.46 du/ac and is within the limits of the R-8 zone. All of the lots meet all dimension requirements of the R-8 zone. The lots offer enough room to meet front, rear and side yard setback requirements. The existing houses must be removed prior to recording the final plat. Access to the subdivision would be via a new road, NE 200 Place that would extend from Duvall through the site and loop down as Field Avenue and connect to NE 200 Street. An additional smaller looped road would extend north from NE 2 00 Place to serve Lots 5 -20. Street frontage improvements would be required along Duvall, NE 2•d Street and Field Avenue NE. A number of the lots will be served via access easements. A Homeowner's Association or Maintenance Agreement should be established to ensure maintenance of access easements and surface water facilities. Regarding the road reservations, one section along the east side of the lot is a right-of-way and the applicant has applied for a vacation of that, it should be approved by Council in October. The rest is reserved, the City had a right to use it as a right-of-way but never did. Property Services has stated that a statement would be placed on the face of the plat releasing that right to ever have it built out. There are offsite wetlands to the east and was categorized as a Category 2, but that has changed due to a drainage pond that was put in by King County, it now meets the criteria of a Category 3 wetland with a 25-foot buffer which does not reach to this site. There is a stream along the east property line, it is a Class 4 stream, which required a 35-foot buffer, code does allow that the buffer can be reduced to 25-feet by meeting certain criteria. The site is fairly flat, most of it is landscaped with some areas of natural vegetation. A revised tree retention plan has been required. 25% of the trees must be retained and/or replaced. The landscape plan shows two trees on the street frontages, however the plan does not show 2 trees on lots without frontage. The code does require trees on each lot, the plan must be revised to add trees to interior lots. The landscaping along Duvall needs to be increased to I 0-feet and 5-feet along NE 2 00 Street and Field. Landscaping has been proposed around the drainage tracts as well, grass for the interior of the tracts. To meet code, landscaping must incorporate the entire tract, not just the interior. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 3 The Environmental Review Committee issued a Determination of Non-Significance -Mitigated with nine mitigation measures. No appeals were filed. Fire, Traffic and Parks Mitigation Fees have been imposed on this plat. Two detention ponds have been proposed by the applicant, one near the center and one in the southeastern corner of the site. The ponds would drain into Field Avenue NE into the existing stormwater system. The detention ponds should be fenced with 6-foot wood fencing and the fences should be set back from the edge of the sidewalk in order to accommodate the landscaping. Water for the site would be supplied by Renton and Water District 90. A water availability certificate has been submitted, Water District 90 stated that the water mains would need to be extended. A dedication ofright-of- way needs to be made along 200 Avenue, Field Avenue and the new streets. Sewer service would be provided by the City of Renton, there are sewer mains in Duvall and in NE 2 00 Street, it will need to be extended along NE 2 00 and through the site. James Jaeger, Jaeger Engineering, 9419 S 204th Place, Kent, WA 98031 stated that he represents J&M Development for this plat. They have reviewed the conditions in the staff report and are in basic agreements with them. He would like to see the dedication of 15-feet along NE 200, on the plans they are showing 12-feet. Currently there is 35-feet of dedication as a result of the Laurelhurst Division II. They have constructed a half street, in order to complete that street, they would have to add an additional 4-feet of pavement and a 5-foot sidewalk. That required 9 feet and they are showing 12-feet for that area. He would like to see the conditions conform to what is on the plans. Setbacks from easement and private roads affect Lots 35, 36, 37, and 38. So those four lost were re-oriented to actually come off the private road, changed from a joint driveway to a private road with 20-feet of pavement in 26 feet. Field Avenue is not yet developed, it will connect with NE z•d Street, which is built up to Laurelhurst Division II. Field will be constructed and be a 90 degree turn onto NE 200 Street when completed. Susan Rider, 1835 NE 20th Street, Renton, WA 98059 stated that she was concerned about the wetlands and now drainage tracts are being placed in the area. If the water is impounded to the drainage tract, what effect wills that have on the outer edges of the wetland. Will the wetland be further degraded by the impoundment of the water that used to go into them? Juliana Fries, Development Services stated that the 10-foot landscape along Duvall is due to not having sufficient right-of-way for the width of the landscape requirement and at the time of recording there was a permanent easement along the required additional footage. In order for the roads to align and meet up, a minimum of 12 feet is needed even though there is currently 28 feet of pavement, in this area there will most likely be 35-36 feet of pavement in order to match the curb and gutter coming into it. The modification is for internal streets to be reduced from SO-feet to 42 feet. She was not aware that it had been granted to NE 200 Street. South of Field is an undeveloped right-of-way and it seems very unlikely that it will ever be developed, therefore, there is no alignment to be maintained. Regarding the private roads, code requires that no more than two non-abutting lots access out of a private driveway, so this could be a private driveway, it does not have to be a private road. Access to Lots 34-39 would require a private road. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page4 The whole site slopes from the east to the southwest, so this site does not con1ribute any water to the offsite wetland. The wetland to the west was filled and removed. Mr. Jaeger stated that the wetland to the east is fed from a stream that comes across NE 4lh and has a substantial drainage basin north of NE 4 ... It enters this wetland and continues along the Class 4 stream that resembles a ditch along the east property line and into the Colony Park subdivision southeast of the site. There was some flooding in that subdivision and in order to rectify that, the County built the pond with a 36" pipe that runs down Field Avenue in order to intercept that stream and route it around the subdivision. So as to not cause any additional drainage issues, they are connecting to the 36" pipe. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at I 0:20 am. FINDINGS, CONCLUSIONS & RECOMMENDATION Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The applicant, Marc Rousso, filed a request for a Preliminary Plat. 2. The yellow file containing the staff report, the State Environmental Policy Act (SEPA) documentation and other pertinent materials was entered into the record as Exhibit # I. 3. The Environmental Review Committee (ERC), the City's responsible official issued a Determination of Non-Significance -Mitigated (DNS-M). 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is located on the north side of NE 2nd Street generally between Duvall Avenue NE and Field Avenue NE, although a portion of the property is located east of Field. 6. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of single-family uses, but does not mandate such development without consideration of other policies of the Plan. 7. The subject site is currently zoned R-8 (Single Family -8 dwelling units/acre). 8. The subject site was armexed to the City with the adoption of Ordinance 5175 enacted in December 2005. 9. The subject site is approximately 364,502 square feet or 8.37 acres in size. The subject site is comprised of seven underlying lots that would be consolidated and re-divided in this process. 10. The subject site is generally flat. Existing single-family residences on the various lots would be removed if the plat were approved. 11. A Class 4 Stream is located just east of the subject site. The stream's required 35-foot buffer does extend onto the subject site. The applicant has been permitted to reduce the buffer width to 25 feet Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 5 subject to creating an enhanced buffer with stream and/or vegetative restoration. Staff recommended that a Native Growth Protection Easement be created for the buffer area in what are proposed lots of the plat. 12. A portion of a Category 3 Wetland is located near the northwest comer of the subject site. The portion of the wetland located off-site has been filled. The portion on the subject site is considered an unregulated wetland at this time. 13. The tree survey shows 260 significant trees and the applicant proposes retaining approximately 60 of those trees. Staff noted that 25% of those trees would require retention of 63 trees. Staff also noted that species were not identified and only significant trees qualify for retention. 14. The applicant proposes dividing the subject site into 49 lots and 2 tracts. The two tracts would be for stonnwater detention. The plat would be divided into two sections by the creation and extension of Field Avenue north and west into the plat. Proposed Lots 1 to 42 and Drainage Tract A would be located between Duvall on the west and Field on the east. Proposed Lots 43 to 49 and Drainage Tract B would be located along the east side of Field. 15. Access to the site would be via NE 2nd Street which runs along the south side of the site, Duvall which runs along the west side of the site and, as noted, the northerly extension of Field into the site and then the westerly creation of NE 2nd Place which will connect Field to Duvall. The applicant shall be required to dedicate street right-of-way for the development and appropriate widening of access streets serving the subject site. The applicant will be creating a number of interior lots that will be accessed through a combination of private easements (26 feet wide) and private driveways (at least 20 feet wide). 16. The density for the plat would be 7.46 dwelling units per acre. 17. The subject site is located within the Renton School District. The project is expected to generate approximately 22 school age children. These students would be spread across the grades and would be assigned on a space available basis. 18. The development will increase traffic approximately JO trips per unit or approximately 470 trips. Approximately ten percent of the trips, or approximately 4 7 additional peak hour trips, will be generated in the morning and evening. 19. Stonnwater would be handled in two detention tracts, one east and one west of Field Avenue NE. Downstream flooding problems have been identified in the area and the applicant will be required to meet the standards of the 2005 King County Manual. The applicant has requested that its detention requirements be based on smaller impervious surface footprints for the proposed lots and subsequent homes and improvements. That modification was granted by the City w.ith the condition that covenants and conditions be imposed on the development limiting homes east of Field to 3,000 square feet of impervious surface and limiting homes west of Field to 3,300 square feet of impervious surface. The ERC also imposed drainage requirements to reduce impacts on the downstream systems. Staff recommends that the detention tracts be fenced. 20. Water service is provided by both the City (west of Field) and Water District 90 (east of Field). The property will have to meet fire flow and pressure requirements. 21. Sewer service will be provided by the City. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page6 22. There are unopened sections of right-of-way affected by the plat as well as two tracts. These will have to be appropriately vacated or abandoned with City approval. CONCLUSIONS: I. The proposed plat appears to serve the public use and interest. The plat creates additional single-family detached housing with a variety of lot sizes. The plat will respect the stream buffer although, reducing that buffer to carve out additional lots in the northeast comer of the plat. The buffer enhancement is the trade-off for this encroachment. 2. The development of the plat will increase the tax base of the City and those taxes should help offset some of the impacts associated with new residents and homes. The applicant will be paying mitigation fees to offset more specific impacts on roads, parks and emergency services. 3. The applicant will have to dedicate property for roads and road widening as well as seek the vacation or abandonment of former right-of-way or reserved tracts. 4. The area is or can be served by the appropriate utility infrastructure including water from two sources and sewer service from the City. The stormwater system has been designed to prevent additional flooding issues downstream although the City did allow a more limited detention system in exchange for limiting the impervious surfaces that would be created by the development of each lot. Hopefully, this will not create an enforcement issue in the future. 5. In conclusion, the division of the subject site appears appropriate to provide additional infill housing in an area where urban services are available and where future residents chose to reside. RECOMMENDATION: The City Council should approve the proposed 47-lot plat subject to the following conditions: I. The applicant shall dedicate land to the appropriate development and widening of public right- of-way to serve the subject plat. 2. The applicant shall comply with all requirements of the Determination of Non-Significance - Mitigated that was issued by the Environmental Review Committee on September 11, 2006. 3. The edge of the stream buffers shall be permanently delineated with a split rail fence and signage shall be installed as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of utility construction permit application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. 4. A Native Growth Protection Easement shall be recorded over the 25-foot stream buffer located on Lots 48 and 49 and on Drainage Tract B prior to or concurrent with the recording of the final plat map. 5. The applicant shall submit a revised Tree Retention Plan, noting the species of the trees on the site. Only the significant trees shall be included in the plan, and 25% of the trees must be identified for retention. The plan shall include information on what measures will be undertaken to assure that the trees are protected during construction. If trees are proposed for Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 7 replacement, the applicant shall justify this. The revised Tree Retention Plan shall be submitted at the time of application for utility construction permits and shall be subject to approval by the Development Services project manager. 6. A revised landscape plan shall be submitted to the Development Service Division project manager for review and approval at the time of application for utility construction permits. The revised landscape plan shall show the planting strip along Duvall Avenue NE increased to the required ten-foot width. It shall illustrate the required five-foot planting strip along all of the other public street frontages. The plan shall illustrate landscaping of the whole detention tracts, not just the perimeter of these. It shall show two trees within the front yard areas of all lots, including the internal lots, which do not abut a public street, and the species and size of the trees shall be noted. 7. The stormwater detention tracts shall be fenced with 6-foot wood fencing prior to recording of the plat. The fence shall be placed behind the required five-foot frontage landscape strip area. The location of the fence shall be shown on the revised landscape plan, and fencing details shall be provided for the review and approval of the Development Services Project Manager prior to recording of the plat. 8. Demolition permits shall be obtained and all inspections completed on the demolition of the existing residences and detached accessory structures prior to final plat approval. 9. A homeowner's association or maintenance agreement shall be established for the development, to ensure that responsibility is taken for maintenance of common improvements and tracts within the plat prior to final plat approval. A draft of the agreement, HOA and/or CC&R documents shall be submitted at the time of application for utilities construction permits, so that it may be reviewed by the City attorney and the Development Services project manager. 10. The applicant shall have "No Parking" signage posted along the 26-foot wide private access easement prior to final plat approval. ORDERED THIS 31st day of October 2006.

Approval to subdivide 8.37 acres into 49 lots and 2 drainage tracts for the eventual construction of single-family detached homes. Development Services Recommendation: Approve subject to conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on October 3, 2006. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area; the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the October JO, 2006 hearing. The legal record is recorded on CD. The hearing opened on Tuesday, October 10, 2006, at approximately 9:34 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No. 2: Preliminary Plat Map application, proof of posting, proof of publication and other documentation oertinent to this request. Exhibit No. 3: Conceptual Drainage and Utility Plan Exhibit No. 4: Tree Plan and Preliminary Grading Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 2 Exhibit No. S: Landsca= Plan (Sheet One) Exhibit No. 7: Excerpt from title report -Road Reservation Plan Exhibit No. 6: Landsca= Plan (Sheet Two) Exhibit No. 8: Zoning Map The hearing opened with a presentation of the staff report by Valerie Kinas!, Senior Planner, Development Services, City of Renton, 1055 S Grady Way, Renton, Washington 98055. The site is located east of Duvall Avenue NE, north of NE 2"" Street. The site is zoned R-8 and the Comprehensive Plan designation is Residential Single-Family. The site consists of seven parcels for a total of 8.3 7 acres, there are five existing homes with accessory structures, all of them will be removed. The proposal for 49 lots arrives at a net density of 7.46 du/ac and is within the limits of the R-8 zone. All of the lots meet all dimension requirements of the R-8 zone. The lots offer enough room to meet front, rear and side yard setback requirements. The existing houses must be removed prior to recording the final plat. • Access to the subdivision would be via a new road, NE 2"" Place that would extend from Duvall through the site and loop down as Field Avenue and connect to NE 2"" Street. An additional smaller looped road would extend north from NE 2"" Place to serve Lots 5 -20. Street frontage improvements would be required along Duvall, NE 2n• Street and Field Avenue NE. A number of the lots will be served via access easements. A Homeowner's Association or Maintenance Agreement should be established to ensure maintenance of access easements and surface water facilities. Regarding the road reservations, one section along the east side of the lot is a right-of-way and the applicant has applied for a vacation of that, it should be approved by Council in October. The rest is reserved, the City had a right to use it as a right-of-way but never did. Property Services has stated that a statement would be placed on the face of the plat releasing that right to ever have it built out. There are offsite wetlands to the east and was categorized as a Category 2, but that has changed due to a drainage pond that was put in by King County, it now meets the criteria of a Category 3 wetland with a 25-foot buffer which does not reach to this site. There is a stream along the east property line, it is a Class 4 stream, which required a 35-foot buffer, code does allow that the buffer can be reduced to 25-feet by meeting certain criteria. The site is fairly flat, most of it is landscaped with some areas of natural vegetation. A revised tree retention plan has been required. 25% of the trees must be retained and/or replaced. The landscape plan shows two trees on the street frontages, however the plan does not show 2 trees on lots without frontage. The code does require trees on each lot, the plan must be revised to add trees to interior lots. The landscaping along Duvall needs to be increased to 10-feet and 5-feet along NE 2"" Street and Field. Landscaping has been proposed around the drainage tracts as well, grass for the interior of the tracts. To meet code, landscaping must incorporate the entire tract, not just the interior. .. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 3 The Environmental Review Committee issued a Determination of Non-Significance -Mitigated with nine mitigation measures. No appeals were filed. Fire, Traffic and Parks Mitigation Fees have been imposed on this plat. Two detention ponds have been proposed by the applicant, one near the center and one in the southeastern comer of the site. The ponds would drain into Field Avenue NE into the existing stormwater system. The detention ponds should be fenced with 6-foot wood fencing and the fences should be set back from the edge of the sidewalk in order to accommodate the landscaping. Water for the site would be supplied by Renton and Water District 90. A water availability certificate has been submitted, Water District 90 stated that the water mains would need to be extended. A dedication of right-of- way needs to be made along 2"" Avenue, Field Avenue and the new streets. Sewer service would be provided by the City of Renton, there are sewer mains in Duvall and in NE 2•• Street, it will need to be extended along NE 2"" and through the site. James Jaeger, Jaeger Engineering, 9419 S 204<h Place, Kent, WA 98031 stated that he represents J&M Development for this plat. They have reviewed the conditions in the staff report and are in basic agreements with them. He would like to see the dedication of 15-feet along NE 2"", on the plans they are showing 12-feet. Currently there is 35-feet of dedication as a result of the Laurelhurst Division II. They have constructed a half street, in order to complete that street, they would have to add an additional 4-feet of pavement and a 5-foot sidewalk. That required 9 feet and they are showing 12-feet for that area. He would like to see the conditions conform to what is on the plans. Setbacks from easement and private roads affect Lots 35, 36, 37, and 38. So those four lost were re-oriented to actually come off the private road, changed from a joint driveway to a private road with 20-feet of pavement in 26 feet. Field Avenue is not yet developed, it will connect with NE 2"" Street, which is built up to Laurelhurst Division IL Field will be constructed and be a 90 degree tum onto NE 2"" Street when completed. Susan Rider, 1835 NE 20"' Street, Renton, WA 98059 stated that she was concerned about the wetlands and now drainage tracts are being placed in the area. If the water is impounded to the drainage tract, what effect wills that have on the outer edges of the wetland. Will the wetland be further degraded by the impoundment of the water that used to go into them? Juliana Fries, Development Services stated that the JO-foot landscape along Duvall is due to not having sufficient right-of-way for the width of the landscape requirement and at the time of recording there was a permanent easement along the required additional footage. In order for the roads to align and meet up, a minimum of 12 feet is needed even though there is currently 28 feet of pavement, in this area there will most likely be 35-36 feet of pavement in order to match the curb and gutter coming into it. The modification is for internal streets to be reduced from 50-feet to 42 feet. She was not aware that it had been granted to NE 2"" Street. South of Field is an undeveloped right-of-way and it seems very unlikely that it will ever be developed, therefore, there is no alignment to be maintained. Regarding the private roads, code requires that no more than two non-abutting lots access out of a private driveway, so this could be a private driveway, it does not have to be a private road. Access to Lots 34-39 would require a private road. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page4 The whole site slopes from the east to the southwest, so this site does not contribute any water to the offsite wetland. The wetland to the west was filled and removed. .. Mr. Jaeger stated that the wetland to the east is fed from a stream that comes across NE 4th and has a substantial drainage basin north of NE 4th. It enters this wetland and continues along the Class 4 stream that resembles a ditch along the east property line and into the Colony Park subdivision southeast of the site. There was some flooding in that subdivision and in order to rectify that, the County built the pond with a 36" pipe that runs down Field Avenue in order to intercept that stream and route it around the subdivision. So as to not cause any additional drainage issues, they are connecting to the 36" pipe. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at I 0:20 am. FINDINGS, CONCLUSIONS & RECOMMENDATION Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: I. The applicant, Marc Rousso, filed a request for a Preliminary Plat. 2. The yellow file containing the staff report, the State Environmental Policy Act (SEPA) documentation and other pertinent materials was entered into the record as Exhibit #1. 3. The Environmental Review Committee (ERC), the City's responsible official issued a Determination of Non-Significance -Mitigated (DNS-M). 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is located on the north side of NE 2nd Street generally between Duvall Avenue NE and Field Avenue NE, although a portion of the property is located east of Field. 6. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of single-family uses, but does not mandate such development without consideration of other policies of the Plan. 7. The subject site is currently zoned R-8 (Single Family -8 dwelling units/acre). 8. The subject site was annexed to the City with the adoption of Ordinance 5175 enacted in December 2005. 9.

The subject site is generally flat. Existing single-family residences on the various lots would be removed if the plat were approved. 11. A Class 4 Stream is located just east of the subject site. The stream's required 35-foot buffer does extend onto the subject site. The applicant has been permitted to reduce the buffer width to 25 feet Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page 5 subject to creating an enhanced buffer with stream and/or vegetative restoration. Staff recommended that a Native Growth Protection Easement be created for the buffer area in what are proposed lots of the plat. 12. A portion of a Category 3 Wetland is located near the northwest comer of the subject site. The portion of the wetland located off-site has been filled. The portion on the subject site is considered an unregulated wetland at this time. 13. The tree survey shows 260 significant trees and the applicant proposes retaining approximately 60 of those trees. Staff noted that 25% of those trees would require retention of 63 trees. Staff also noted that species were not identified and only significant trees qualify for retention. 14. The applicant proposes dividing the subject site into 49 lots and 2 tracts. The two tracts would be for stormwater detention. The plat would be divided into two sections by the creation and extension of Field Avenue north and west into the plat. Proposed Lots I to 42 and Drainage Tract A would be located between Duvall on the west and Field on the east. Proposed Lots 43 to 49 and Drainage Tract B would be located along the east side of Field. 15. Access to the site would be via NE 2nd Street which runs along the south side of the site, Duvall which runs along the west side of the site and, as noted, the northerly extension of Field into the site and then the westerly creation of NE 2nd Place which will connect Field to Duvall. The applicant shall be required to dedicate street right-of-way for the development and appropriate widening of access streets serving the subject site. The applicant will be creating a number of interior lots that will be accessed through a combination of private easements (26 feet wide) and private driveways (at least 20 feet wide). 16. The density for the plat would be 7.46 dwelling units per acre. 17. The subject site is located within the Renton School District. The project is expected to generate approximately 22 school age children. These students would be spread across the grades and would be assigned on a space available basis. 18. The development will increase traffic approximately 10 trips per unit or approximately 470 trips. Approximately ten percent of the trips, or approximately 47 additional peak hour trips, will be generated in the morning and evening. 19. Stormwater would be handled in two detention tracts, one east and one west of Field Avenue NE. Downstream flooding problems have been identified in the area and the applicant will be required to meet the standards of the 2005 King County Manual. The applicant has requested that its detention requirements be based on smaller impervious surface footprints for the proposed lots and subsequent homes and improvements. That modification was granted by the City with the condition that covenants and conditions be imposed on the development limiting homes east of Field to 3,000 square feet of impervious surface and limiting homes west of Field to 3,300 square feet of impervious surface. The ERC also imposed drainage requirements to reduce impacts on the downstream systems. Staff recommends that the detention tracts be fenced. 20. Water service is provided by both the City (west of Field) and Water District 90 (east of Field). The property will have to meet fire flow and pressure requirements. 21. Sewer service will be provided by the City. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page6 22. There are unopened sections of right-of-way affected by the plat as well as two tracts. These will have to be appropriately vacated or abandoned with City approval. CONCLUSIONS: I.

This request shall set forth the specific ambiguities or errors discovered by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. An appeal to the City Council is governed by Title IV, Chapter 8, Section 110, which requires that such appeal be filed with the City Clerk, accompanying a filing fee of$75.00 and meeting other specified requirements. Copies of this ordinance are available for inspection or purchase in the Finance Department, first floor of City Hall. An appeal must be filed in writing on or before 5:00 p.m .. November 14. 2006. If the Examiner's Recommendation or Decision contains the reqnirement for Restrictive Covenants, the execnted Covenants will be required prior to approval by City Council or final processing of the file. You may contact this office for information on formatting covenants. The Appearance of Fairness Doctrine provides that no ex parte (private one-on-one) communications may occur concerning pending land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. Magnussen Preliminary Plat File No.: LUA-06-053, ECF, PP October 31, 2006 Page9 The Doctrine applies not only to the initial public hearing but to all requests for Reconsideration as well as Appeals to the City Council.

Box 2566 Renton, Washington 98056 Subject: Stream Buffer Enhancement Plan Magnussen Preliminary Plat LUA-06-053 Renton, Washington Dear Mr. Rousso: 6500 126'" Avenue S.E. Bellevue, Washington 98006-3941 (425) 641-9743 (425) 643-3499 (fax) chad@chadannour.com In their September 11, 2006 letter, the City of Renton (Renton) requested that JayMarc Development (Proponent) submit a plan to enhance the buffer adjacent to the off-site stream and Lots 48, 49, and Tract B. The following is our plan to enhance the stream buffer within 25 feet of the off-site stream. Background Information The 8.3-acre site is the location of several single-family dwellings, mowed lawn, gardens, and forest. It is located north of NE 2nd Street in Section 15, Township 23 North, Range 5 East, in Renton, Washington (Figure 1 ). The area of interest is located in the southeast corner of the site (Figure 2). The buffer is extensively vegetated with native trees and shrubs with less than 5 percent non-native invasives on slopes less than 15 percent. The overstory layer is dominated by big-leaf maple (Acer macrophylfum) and western red cedar (Thuja plicata) trees. Several large black cottonwood (Populus balsamifera) trees stick up higher than the canopy. Big-leaf maple saplings that grow under the overstory canopy and cascara (Rhamnus purshiana) are more or less common. The shrub layer is typically dominated by hazelnut (Cory/us comuta) and vine maple (Acer circinatum). Also present in the shrub layer are salmonberry (Rubus spectabilis), ocean-spray (Holodiscus discolor'), and Indian plum (Oemleria cerasiformis). The herbaceous layer is typically dominated by sword fern (Po/ystichum munitum) and trailing blackberry (Rubus ursinus). Other native plant species also present in the herbaceous layer are Cascade Oregongrape (Mahonia nervosa), salal (Gaultheria shallon), and bracken (Pteridium aquilinum). Renton's consultant reported that non-native invasives are present at three locations within the buffer. Himalayan blackberry (Rubus discolor') vines (canes) are located at the north and south part of the buffer, English ivy (Hedera helix) at the north end of the buffer south of the Himalayan blackberry, and a patch of bishop's hat (Epimedium sp.) in the middle section of the buffer. C:/Jobs/J&M/Lindberg/Enhancement Plan.doc Chad Armour, LLC 09122/06 Buffer Enhancement Pia Renton, Washington Stream Buffer Enhancement Plan & M Land Development • Remove all of the Himalayan blackberry plants in the buffer within 25 feet of the off-site stream. Remove the entire plant, including canes as well as the near- surface roots. These plants are concentrated on the north and south ends of the buffer. Discard the removed plants off of the site. • Remove all of the English ivy plants in the buffer within 25 feet of the off-site stream. Remove the entire plant including the roots and any vines clinging to the trunks of trees. If vines on tree trunks are out of reach, remove as much of the vine as possible. This plant is concentrated on the north end of the buffer. Discard the removed plant off of the site. • Remove all of the bishop's hat plants in the buffer within 25 feet of the off-site stream. Remove the entire plant including the roots and discard them off of the site. This plant species is concentrated in the middle section of the buffer. Because the buffer is well-vegetated with native plant species, it is not necessary to install native plant species where the non-native plant species are removed. Native plant species will likely naturally colonize the treated areas. The Proponent will identify the treatment areas in advance of treatment. Treatment shall occur simultaneous to site grading. A qualified biologist will flag the treatment areas prior to treatment.

It is intended for the exclusive use of JayMarc Development and their assigns for specific application to the referenced property. This letter is not meant to represent a legal opinion.

Because the applicants are proposing to convert the house to an office use and the lot is abutting a residentially zoned property, a 15 ft. lanscape strip is required along the south property line. The applicants are also required to provide four onsite parking stalls. Given the lot width and placement of the existing house, it is not possible for the applicants to provide required parking and also the 15 ft. of landscaping. For this reason the applicants are requesting that the requirement to provide a 15 ft. wide sight-obscuring landscape stirp along the south property line to be reduced to zero.

PROJECT DESCRIPTION/BACKGROUND Preliminary Report to the Hearing Examiner LUA..06..053, PP, ECF Page 4 of 12 The 8.37 acre site is bounded to the west by Duvall Avenue NE, to the south by NE 2°• Street, to the east by single family detached residential development and to the north by a commercial mini-storage facility. There are currently five homes and a number of accessory structures on the site, which would be removed as part of the proposal. The applicant is proposing to subdivide the 8.37-acre site located in the Residential -8 dwelling units per acre (R- 8) zone into 49 lots and 2 drainage tracts for the eventual construction of single-family detached homes. The resulting net density would be 7.46 dwelling units per acre. The lot sizes would range from 4,517 square feet to 8,540 square feet. Primary access to the lots would be from a new road, NE 200 Place. which would extend from Duvall Avenue NE through the site and loop down, as Field Avenue NE. to connect with NE 2°• Street. A smaller loop of road, Street A, would provide public access for Lots 5 through 20. Lots 9, 10, 15, 16, 34, 35, 38, 39, 48 and 49 would be accessed via 20 foot wide private access easements. The applicant applied for a received a modification to reduce the required right-of-way width of the public streets from 50 feet to 42 feet, which would include 32 feet of paving, and curbs, gutters and sidewalks on both sides. Street improvements to Duvall Avenue NE and NE 200 Street would be required along the frontages of the site. Two areas on the site were reserved for public roads under a previous plat under King County jurisdiction. The subdivision was never built. The reserved area is no longer necessary for roads, and the City will likely release it concurrently with plat approval and recording, because the new design for subdivision of the property provides a different pattern of public access through the site. A small segment of the road located at proposed Lot 20 is actual right-of-way, which must be vacated prior to recording of the plat. The vacation is in process in the City and would likely be approved by the Renton City Council this month, October, 2006. There is a Class 4 stream just east of the site. The 35-foot buffer of this stream extends onto Lots 48, 49 and Drainage Tract B. The applicant requested a reduction of the stream buffer from 35 feet to 25 feet It was approved during the Environmental Review process because it met the critical areas regulations buffer reduction criteria, which allow a reduction to 25 feet if the vegetation consists of native vegetation with less than 5% invasive species. The applicant is required to complete buffer enhancement to meet the critical areas requirements. There is also a Category 3 wetland to the northeast of the site, near proposed Lots 15 and 16. The 25 foot buffer of this wetland does not extend onto the Magnussen site. There is a Category 3 wetland on the parcel at the northwestern corner of the plat, which extends very slightly into proposed Lots 3 and 4. The portion of this wetland on the neighboring lot has been filled and the small remaining part is unregulated due to its size. The site is relatively fiat. The soils at the site are Alderwood gravelly sandy loam. The applicant proposes clearing and grading for the roads, building pads, utilities and detention ponds. An estimated 4,500 cy of soil would be excavated and then used as fill on the site so there would be a balance of cut and fill. The new surface water that would result from the development would be detained and treated in two new detention ponds, located on tracts at the southeastern corner of the site and just southeast of the center of the site. The site vegetation consists of residential landscaping, areas of native vegetation and approximately 250 significant trees. The applicant has proposed to retain approximately 60 significant trees. The applicant has submitted a conceptual landscaping plan showing two new trees in the front yard of each lot, except the lots not abutting a public street. The landscaping plan also illustrates a six-foot wide landscape strip along Duvall Avenue SE and in some areas along the new internal streets. An approximately ten-foot wide landscape strip is proposed along the perimeter of the drainage tracts, with hydroseeded grass on the interior of the tracts. Surface water drainage was designed according to the 2005 King County Surface Water Manual. Two drainage ponds are proposed which would discharge into existing storm water mains. Water service would be provided by the City of Renton and Water District 90. The water mains will be required to be extended in several areas, including NE 200 Street, Field Avenue NE, and the new interior streets. Sewer main extensions will also be required to the east property line and along Field Avenue NE. HEX Report 06-053.doc City of Renton PIBIPW Departme, MAGNUSSEN PRELIMINARY PLAT PUBLIC HEARING DATE: October 10, 2006 2. ENVIRONMENTAL REVIEW Preliminary Report to the Hearing Examiner LUA-06-()53, PP, ECF Page5of12 Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21 C, 1971 as amended), on September 11, 2006, the Environmental Review Committee issued a Determination of Non-Significance - Mitigated (DNS-M) for the Magnussen Preliminary Plat. The DNS-M included nine mitigation measures. A 14-day appeal period commenced on September 18, 2006 and ended on October 2, 2006. No appeals of the threshold determination were filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES 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 comply with the recommendations contained in the geotechnical report prepared by Earth Solutions NW, LLC, dated April 13, 2006 under "Site Preparation and Earthwork, "Detention Pond Recommendations," and "Utility Trench Backfill." 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements, outlined in Volume II of the 2001 Stormwater Management Manual, and provide staff with a Construction Mitigation Plan prior to issuance of construction permits. This Plan shall be subject to the review and approval of the Development Services Division. 3. The applicant shall comply with the 2005 King County Surface Water Design Manual to meet both detention (conservation flow control) and water quality (basic) improvements. 4. The applicant shall comply with the recommendation contained on the Drainage Report by Jim Jaeger, P.E., revised on August 2, 2006, with regards to the re-routing of the natural discharge location of pond B to the existing 36-inch pipe. 5. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $488.00 per new single-family lot prior to the recording of the final plat. 6. The applicant shall remove the sight obscuring tree branches, noted in the Traffic Impact Analysis by Gibson Traffic Consultants, at the intersection of NE 2"" Street and Jericho Avenue NE and provide Development Services with proof of this at the time of submittal for street construction permits. 7. The applicant shall pay the appropriate Traffic Mitigation Fee based on $75.00 per each new average daily trip associated with the project prior to the recording of the final plat. 8. The applicant shall pay the appropriate Parks Mitigation Fee based on $530.76 per new single-family lot prior to the recording of the final plat. 9. The existing water well shall be decommissioned according to applicable King County and/or Washington State regulations prior to final plat approval. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. HEX Report 06-053.doc City of Renton PIB/PW Departmen MAGNUSSEN PRELIMINARY PLA I PUBLIC HEARING DA TE: October 10, 2006 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Preliminary Report to the Hearing Examiner LUA-06-053 PP ECF Page 6 of 12 Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The subject site is designated Residential Single Family (RSF} on the Comprehensive Plan Land Use Map. The objective established by the RSF designation is to protect and enhance single-family neighborhoods. The proposal is consistent with the RSF designation in that ii would provide for the future construction of single-family homes. The proposed plat is consistent with the following Comprehensive Plan objectives and policies for Residential Single Family Land Use, and Environmental Elements: Land Use Element Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per net acre in Residential Single Family neighborhoods. The proposal for 49 lots on the subject site would arrive at a net density of 7.46 dwelling units per net acre after the required deductions, which is within the density range permitted in the R-8 zone. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than an acre (43,560 square feet) in single-family designations. Allow a reduction in lot size to 4,500 square feet on parcels greater than an acre to create an incentive for aggregation of land. The site is greater than one acre and all lots would be greater than or equal lo 4,500 square feel Policy LU-149. Lot size should exclude private sidewalks, easements, private road, and driveway easements, except alley easements. There are four private access easements proposed to serve interior lots. The area within the private access easements was subtracted from the gross lot area of each affected lot. Environmental Element Objective EN-C: Protect and enhance the City's rivers, major and minor creeks and intermittent stream courses. The proposal would be consistent with the objective provided recommended conditions are followed. Staff recommends, under Topography and Vegetation below, that a Native Growth Protection Easement be placed over the buffer of the stream, which extends over part of Lots 48 and 49, and Drainage Tract B. A split rail fence and signage is recommended to be installed indicating that this is a protected natural area. This would protect the buffer from future impacts. The applicant should also be required to complete enhancement of the buffer, which would entail removal of invasive species, before the plat is recorded. B. Compliance with the Underlying Zoning Designation. The 8.37-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of up to 49 new single-family residential units. Density -The allowed maximum density in the R-8 zone is a minimum of 4.0 dwelling units per net acre (dulac} to a maximum of 8.0 dwelling units per net acre. Net density is calculated after public rights-of- way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 74,344 square feet of proposed right-of-way dedication and 4,150 square feet of private access easements the proposal for 49 lots would result in a net density of 7.46 dwelling units per acre (364,502 gross square feet-74,344 square feet-4, 150 square feet= 286,008 square feet or 6.57 acres, 49 units/ 6.57 acres = 7.46 du/ac). The proposed plat would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone for sites over one acre in size is 4,500 sq feet. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. Proposed lot widths range from 50 to 80 feet and lot depths HEX Report 06-053.doc City of Renton PIB/PW Deparlmen MAGNUSSEN PRELIMINARY PLAT PUBLIC HEARING DA TE: October 10, 2006 Preliminary Report to the Hearing Examiner LUA-06-053, PP, ECF Page 7 of 12 range from 95 feet to 123.42 feet. The proposed plat would create 49 lots, which are proposed to range from 4,517 square feet in area to 7,800 square feet. As proposed, all lots appear to be in compliance with the required lot width, depth and size standards. Setbacks -Building setbacks required in the R-8 zone include a front yard and side yard along a street setback of 15 feet for the primary structure and 20 feet for attached garages, an interior side yard setback of 5 feet, and a rear yard setback of 20 feet. The building setback requirements for the new residences would be reviewed at the time of building permit review, however the proposed lots appear to contain adequate area to provide all the required setback areas. The setback envelopes shown on the preliminary plat drawing submitted on September 7, 2006 appear to be accurate, except that Lots 9, 15, 39 and 49 would require the setbacks to be measured from the access easement. Staff recommends that the applicant consult with the Development Services Division planner who will be reviewing the building permits about how to measure the setbacks from access easements. Because the plat is not designed to accommodate the existing houses and they would likely not meet their setback requirements, staff recommends that the applicant be required to demolish or remove all existing houses prior to recording of the final plat. Building Standards -The R-8 zone permits one residential structure per lot. Each of the proposed lots would support the construction of one detached single family residence. Accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. The applicant has indicated that the existing five homes, and their accessory structures would be removed. Staff recommends as a condition of preliminary plat approval, that the applicant be required to have the houses and accessory structures removed or demolished prior to final plat recording. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. The R-8 zone restricts lots greater than 5,000 square feet in size to a maximum building coverage of 35% or 2,500 square feet, whichever is greater. The height and lot coverage of the new houses would be verified at the time of application for building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum width of landscaping required along the street frontage for sites abutting an arterial street, such as Duvall Avenue NE, is ten feet. Along a non-arterial public street five feet of landscaping must be installed. If there is additional undeveloped right-of-way in excess of the five or ten feet, this must also be landscaped. If sufficient area is not available within the public right-of-way due to required improvements, the landscape strip may be located within private property abutting the public right-of-way. The landscaping proposed shall either consist of drought resistant vegetation or shall be irrigated appropriately. In addition, the applicant is required to plant two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer), within the 15-foot front yard setback area for the proposed lots or within the proposed planting strip. A conceptual landscape plan was submitted with the project application. The landscape plan proposes a six-foot landscaped strip along Duvall Avenue NE. Ten feet would be required to meet the development re~ulations, so this would not meet the requirements. Between five and nine feet are proposed along NE 2" Street, which would meet the requirement. Along the new interior public streets, landscaping is only proposed in limited areas. This would not meet the requirement of five feet of landscaping along non- arterial public roads. Around the detention ponds, the applicant proposes perimeter landscaping and hydroseeding of grass in the remaining area. This would not meet the landscape regulations requirement to landscape and maintain all pervious areas. Grass would become overgrown and perhaps dangerous in the dry summer months. Plantings that can be adequately maintained would be required over the whole tracts. except in the ponds themselves. Staff recommends as a condition of plat approval, that the applicant be required to submit a revised landscape plan illustrating adequate landscaping along the public streets and on the drainage tracts at the time of submittal for utility construction permits. HEX Report 06-053.doc City of Renton PIB/PW Departmen MAGNUSSEN PRELIMINARY PLA, PUBLIC HEARING DA TE: October 10, 2006 Preliminary Report to the Hearing Examiner LUA-06-053, PP ECF Page 8of 12 The landscape plan also proposes two new trees in the front yard area of most of the new lots, as required. The applicant has provided more trees than required on some lots, and none on the lots without street frontage, Lots 9, 10, 15, 16, 34, 35, 38, 39, 48, and 49. Staff recommends that the revised landscape plan, recommended above, also illustrate two new trees on these lots. The size and species name shall also be noted on the plan. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. The lots in the Magnussen Preliminary Plat are at right angles to the streets and have access to public roads. Lots: The size, shape and orientation of lots must meet the minimum area and width requirements of the applicable zoning classification and must be appropriate for the type of development and use contemplated. Each of the proposed lots is rectangular in shape, oriented to provide front yards facing a street or private access easement, and satisfies the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: All lot corners at intersections of dedicated public rights-of-way, except alleys, shall have minimum radius of 15 feet. Access and Street Improvements: There are currently no curbs, gutters or sidewalks along the frontage of the site along Duvall Avenue NE, NE 2°• Street or Field Avenue NE. The applicant will be required to provide these. To do this, dedication of a minimum of twelve feet will be required along Field Ave NE. Dedication of 15 feet along NE 2nd Street will be required. Street improvements including, but not limited to pavement, curb/gutter, sidewalks, streetlights street signs and landscape will be required. Along the new streets, street improvements including, but not limited to paving, sidewalks, curb and gutter, storm drain, landscape, street lighting and street signs will be required. Corner lots must dedicate a minimum radius of fifteen feet. All wire utilities shall be installed underground per the City of Renton Undergrounding Ordinance. Primary access to the lots would be from a new road, NE 2"" Place, which would extend from Duvall Avenue NE through the site and loop down, as Field Avenue NE, to connect with NE 2"" Street. A smaller loop of road would provide public access for Lots 5 through 20. The applicant requested and was granted a modification to reduce the required right-of-way width of the public streets from 50 feet to 42 feet, which would include 32 feet of paving, and curbs, gutters and sidewalks on both sides. Lots 9, 10, 15, 16, 34, 35, 38, 39, 48 and 49 would be accessed via 26-foot wide private access easements. In order to ensure efficient emergency access to the development is not obstructed, staff recommends as a condition of preliminary plat approval the applicant be required to place "No Parking" signage along the 26-foot wide private access easement prior to final plat approval. In addition, staff recommends a condition of approval requiring the establishment of a homeowner's association or maintenance agreement for the development, which would be responsible for any common improvements and/or tracts within the plat prior to final plat approval. There is an isolated segment of unused right-of-way in Lot 20 and extending into proposed NE 200 Place. The applicant has applied for a vacation of this right-of-way and Property Services. Staff have indicated that they will likely recommend approval to the City Council in October 2006. Also, there are two tracts of a previous recorded subdivision of the property, which was never built out, which would need to be released by the City. They are shown in Exhibit 7. Tract X extends from Duvall Avenue NE east and ends in a cul-de-sac at approximately where proposed Lots 21 and 24 are. Tract Y extends along the east property line from about Lot 15 through 20. Because the plat was never constructed, and the Magnussen Preliminary Plat has redesigned the subdivision under new zoning regulations, the necessity for roads specifically in the location of these tracts is no longer given. Property Services has indicated that because the City never exercised its right to convert this area to right-of-way, it is possible to release the property at the time the new plat and its associated right-of-way dedication are recorded. The applicant has submitted a proposal for the wording of the release and a copy has been forwarded to Property Services for review. HEX Report 06-053.doc City of Renton P/BIPW Departmen MAGNUSSEN PRELIMINARY PLAT PUBLIC HEARING DA TE: October 10, 2006 Preliminary Report to the Hearing Examiner LUA-06-053, PP, ECF Page 9of 12 To mitigate impacts to the local street system, the City's Environmental Review Committee requires the payment of a Traffic Mitigation Fee based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 49 new residential lots with credit given for the five existing residences would be expected to generate approximately 469 new average weekday trips based on 9.57 daily trips. The fee for the proposed plat is estimated to be $35,175 (469 total trips x $75.00) and is payable prior to the recording of the plat. Topography and Vegetation: The site is relatively flat. The soils at the site are Alderwood gravelly sandy loam. The applicant proposes clearing and grading for the roads, building pads, utilities and detention pond. An estimated 4,500 cy of soil would be excavated and then used as fill on the site so there would be a balance of cut and fill. Mitigation measures imposed by the Environmental Review Committee require that temporary erosion and sedimentation control be provided at the site during construction. There is a class 4 stream just outside the eastern most boundary of the site, which requires a 35-foot buffer that extends onto the site. The applicant has requested a buffer reduction under RMC 4-3- 050L.5.c.ii to reduce the stream buffer to a 25-foot enhanced buffer. This buffer reduction was approved under the Environmental Review of the project. The applicant has since submitted a Stream Buffer Enhancement Plan, dated September 22, 2006, completed by his consultant, Chad Armour, LLC to meet critical areas regulations. In addition, a condition is recommended, requiring that a Native Growth Protection Easement be recorded over the 25-foot stream buffer located on Lots 48, 49, and on Drainage Tract B prior to or concurrent with the recording of the final plat map. Fencing of the edge of the stream buffer with a split rail fence is also recommended. Signage should be required to be installed subject to approval by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the lime of utility construction permit application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The site vegetation consists of residential landscaping, and native vegetation along the eastern portion of the property. There are approximately 250 significant trees. The applicant has proposed to retain approximately 60 of these. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made lo preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. To comply with this Determination, the applicant would be required to retain 63 trees (outside of the Native Growth Protection Easement). If this is absolutely not possible, some of the trees may be replaced at a ratio of one to one with trees of a minimum caliper of 2 inches. A Tree Plan, Exhibit 4, was submitted for the project, indicating 60 trees to be retained. The plan did not indicate the species of the deciduous trees on the site. Certain trees, such as poplars and cottonwoods are not considered significant trees. Staff recommends as a condition of preliminary plat approval, that the applicant be required to submit a revised Tree Plan, noting the species of the trees on the site. Only the significant trees should be included, and at least 63 trees should be identified for retention. The plan should include information on what measures will be undertaken to assure that the trees are protected during construction. If trees are proposed for replacement, the applicant shall justify this. The revised Tree Retention Plan shall be submitted at the time of application for utility construction permits and shall be subject to approval by the Development Services project manager. Relationship to Existing Uses: There are five existing homes on the site of the Magnussen plat that would be removed in order to accommodate the new lots. To the north of the Magnussen Preliminary Plat is a mini-storage facility in the CA zone. Just west of the north part of the site is the six-lot MB Short Plat, which has received preliminary approval. The zoning to the west, east and south of the site is R-8. Across Duvall Avenue NE is the Laurelhurst subdivision and to the south is the second phase of the Laurelhurst plat. To the east are single family homes that were built in the 1980s and 1990s on large lots. The West Coast preliminary plat is proposed to the northeast of the Magnussen site. The proposal for 49 detached single family lots is consistent with the guidelines of both the Comprehensive Plan and zoning code and would not be out of character with the existing or recent development in the area. HEX Report 06-053.doc Cfty of Renton P/8/PW Departmen MAGNUSSEN PRELIMINARY PLAT PUBLIC HEARING DA TE: October 10, 2006 D. Availability and Impact on Public Services {Timeliness) Preliminary Report to the Hearing Examiner LUA-06-053, PP, ECF Page 10 of 12 Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. Therefore, the City's Environmental Review Committee is requiring the applicant to pay a Fire Mitigation Fee based on $488 per new single-family home. The fee is estimated at $21,472 (44 new lots x $488) and is payable prior to the recording of the plat. The requirements for fire prevention associated with water provision can be found under the section Water and Sanitary Sewer Utilities below. Fire department access roads must be paved to a minimum width of 20 feet. Dead end roadways over 150 feet in length are required to have an approved turnaround. Street addresses must be visible from a public street. Recreation: The proposal would not include any commonly owned recreation areas for future residents of the proposed plat. There are no existing recreational facilities in the immediate vicinity of the subject property, however the currently undeveloped Maplewood Park is in the project vicinity. It is anticipated that the proposed development would generate future demand on existing City Parks and recreational facilities and programs. Therefore, the City's Environmental Review Committee is requiring the applicant to pay a Parks Mitigation Fee based on $530. 76 per new single-family home. The fee is estimated at $23,353.44 (44 new lots x $530.76) and is also payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 22 additional students (0.44 x 49). Children in the new subdivision would be assigned to Maplewood Elementary School, McKnight Middle School, or Hazen High School. The school district has indicated that they would be able to accomodate additional students coming from the proposed development. Storm Drainage/Surface Water: A Preliminary Technical Information Report prepared by James J. Jaeger, P. E., dated April 24, 2006 was submitted with the application materials, containing information on how the project would comply with the 2005 King County Surface Water Design Manual. An addendum, dated July 18, 2006, to the report was submitted upon request of City staff, updating the offsite analysis, providing downstream drainage complaint documentation, and providing revised drainage requirement calculations. The applicant applied for and was granted a modification on August 31, 2006 by Kayren Kittrick of Development Services, to allow the calculation of drainage pond capacity using impervious area assumptions lower than those found in the King County Manual. According to the addendum report surface water runoff currently flows east into the abutting stream and wetlands. Downstream, the water drains through the older subdivision, Puget Colony Homes, southeast of the site. There have been flooding problems in the Puget Colony Homes subdivision in the past, as the submitted reports of complaints demonstrates. To meet the 2005 King County Surface Water Management Manual, the applicant is proposing two detention ponds. In a request for modification to the City, the applicant proposed calculating the pond capacity assuming a lower level of impervious area than required in the 2005 King County Manual. On August 31, 2006, Kayren Kittrick approved a modification to allow the applicant to reduce the amount of assumed future impervious area per lot used for the calculations to 3,300 square feet for the lots served by Pond A and 3,000 square feet for lots served by Pond B. Conditions of this decision where that these limits of the impervious area be noted on the face of the plat, recorded in a covenant and listed in the CC&Rs of the HOA. The larger of the two proposed detention ponds, in Tract A, is located just southeast of the center of the site. The other, in Tract B, is at the southeastern corner of the site. Pond A would connect to the existing surface water drainage system in NE 2"" Street. The Environmental Review Committee required in a mitigation measure that Pond B discharge to the existing 36 inch drainage main in Field Avenue NE. This was required to avoid additional risk of flooding at Puget Colony Homes, by not allowing surface water discharge into the existing culvert at the southeast of the site. For safety reasons, staff recommends as a condition of approval that the stormwater detention tracts be fenced with 6-foot wood fencing. The fence should be placed behind the required five foot frontage landscape strip area. The fence shall be shown on the revised landscape plan and fencing details shall HEX Report 06-053.doc City of Renton PIBIPW Departmen MAGNUSSEN PRELIMINARY PLAT PUBLIC HEARING DA TE: October 10, 2006 Preliminary Report to the Hearing Examiner LUA-06-053, PP, ECF Page 11 of 12 be provided for the review and approval of the Development Services Project Manager prior to recording of the plat. A Surface Water System Development Charge, based on the current rate of $759.00 per new single- family lot, would be required prior to the issuance of construction permits for the plat. Water and Sanitary Sewer Utilities: The subject site is partially in the City of Renton and partially in the area of Water District 90. Water District 90 supplies water service to the area east of Field Avenue NE. A certificate of water availability from WD 90 was submitted by the applicant upon submittal for preliminary plat review. The certificate of water availability provided for the project from King County DDES states that an improvement of the water system will be required in order to serve the new subdivision. A 175 foot water main extension and/or replacement of the AC main in NE 2"" Street in front of the property will be required. Water is available at no less than 20 psi measured at the nearest fire hydrant, 580 feet from the property. Flow there is 1,000 gpm or more for two hours or more. The City of Renton provides water service in the portion of the plat west of Field Avenue NE. In that part of the plat, there is an existing twelve-inch water main in Duvall Ave NE that can deliver a flow rate of 2,500 gallons per minute (gpm). The static water pressure is about 75 psi at street elevation (see City water civil drawing no. W-0943). There is also an eight-inch water main along NE 2"" St that can deliver 1,250 gpm (see City water civil drawing No. W-3265). Static pressure varies from 71 to 75 psi. The Pressure Zone is 565. The proposed project is located outside the Aquifer Protection Area. A water main extension (eight-inch minimum diameter) within the new streets interior to the plat will be required. A water main extension along Field Ave NE, and connecting to the existing main in NE 2nd St will be required. Water main extension to the west property line (along the northerly line of proposed Lot 8), along with a 15-foot utility easement, and connecting to a recently installed water main will be required. New water service stubs to each lot must be installed in conjunction with the above water main extension prior to recording of the plat. The Water System Development Charge (SDC) would be triggered at the single-family rate of $1,956 per new single-family per building lot. This fee is payable at the time the utility construction permit is issued. To ensure adequate fire fighting service can be provided, existing and new hydrants will be required to be retrofitted with Storz "quick disconnect" fittings, if not already in place. A fire hydrant with 1,000 gpm fire flow is required within 300 feet of all new single family structures. If the building square footage exceeds 3,600, including the garage, the minimum fire flow increases to a minimum of 1,500 gpm and requires two fire hydrants within 300 feet of the structure. The subject property is served by City of Renton sewer service. There is an eight-inch sewer main in Duvall Ave NE, north of the northerly property line (fronting Duvall Ave NE -drawing S-3195). There is also an eight-inch sewer main on NE 2°• Street (drawing S-3265). A sewer main extension to the east property line will be required. The sewer main shall be installed at a depth that will allow sewer mains extensions to provide gravity sewer as far as possible. A sewer main extension along Field Ave NE will also be required. The plat is in the East Renton Interceptor Special Assessment District (SAD). Fees for this are collected at the lime the utility construction permit is issued. The Sanitary Sewer System Development Charges (SDC) is $1,017 per building lot. This fee is payable at the time the utility construction permit is issued. Prior to recording the plat, any existing septic systems must be abandoned in accordance with the King County Department of Health regulations. H.

Bellevue, Washington 98006-3941 (425) 641-9743 (425) 643-3499 (fax) chad@chadannour.com In their September 11, 2006 letter, the City of Renton (Renton) requested that JayMarc Development (Proponent) submit a plan to enhance the buffer adjacent to the off-site stream and Lots 48, 49, and Tract B. The following is our plan to enhance the stream buffer within 25 feet of the off-site stream. Background Information The 8.3-acre site is the location of several single-family dwellings, mowed lawn, gardens, and forest. It is located north of NE 2nd Street in Section 15, Township 23 North, Range 5 East, in Renton, Washington (Figure 1 ). The area of interest is located in the southeast corner of the site (Figure 2). The buffer is extensively vegetated with native trees and shrubs with less than 5 percent non-native invasives on slopes less than 15 percent. The overstory layer is dominated by big-leaf maple (Acer macrophyllum) and western red cedar (Thuja plicata) trees. Several large black cottonwood (Populus ba/samifera) trees stick up higher than the canopy. Big-leaf maple saplings that grow under the overstory canopy and cascara (Rhamnus purshiana) are more or less common. The shrub layer is typically dominated by hazelnut (Cory/us comuta) and vine maple (Acer circinatum). Also present in the shrub layer are salmonberry (Rubus spectabilis), ocean-spray (Holodiscus discolor'), and Indian plum (Oemleria cerasiformis). The herbaceous layer is typically dominated by sword fern (Polystichum munitum) and trailing blackberry (Rubus ursinus). Other native plant species also present in the herbaceous layer are Cascade Oregongrape (Mahonia nervosa), salal (Gaultheria shal/on), and bracken (Pteridium aquilinum). Renton's consultant reported that non-native invasives are present at three locations within the buffer. Himalayan blackberry (Rubus discolor') vines (canes) are located at the north and south part of the buffer, English ivy (Hedera helix) at the north end of the buffer south of the Himalayan blackberry, and a patch of bishop's hat (Epimedium sp.) in the middle section of the buffer. C:/Jobs/J&M/Lindberg/Enhancement Plan.doc Chad Armour, LLC 09/22/06 Buffer Enhancement Plan Renton, Washington Stream Buffer Enhancement Plan M Land Development • Remove all of the Himalayan blackberry plants in the buffer within 25 feet of the off-site stream. Remove the entire plant, including canes as well as the near- surface roots. These plants are concentrated on the north and south ends of the buffer. Discard the removed plants off of the site. • Remove all of the English ivy plants in the buffer within 25 feet of the off-site stream. Remove the entire plant including the roots and any vines clinging to the trunks of trees. If vines on tree trunks are out of reach, remove as much of the vine as possible. This plant is concentrated on the north end of the buffer. Discard the removed plant off of the site. • Remove all of the bishop's hat plants in the buffer within 25 feet of the off-site stream. Remove the entire plant including the roots and discard them off of the site. This plant species is concentrated in the middle section of the buffer. Because the buffer is well-vegetated with native plant species, it is not necessary to install native plant species where the non-native plant species are removed. Native plant species will likely naturally colonize the treated areas. The Proponent will identify the treatment areas in advance of treatment. Treatment shall occur simultaneous to site grading. A qualified biologist will flag the treatment areas prior to treatment.

ERC Report Magnussen City of Renton PIBIPW Department MAGNUSSEN PRELIMINARY PLAJ Envir ,ental Review Committee Staff Report REPORT OF September 11, 2006 IIPART ONE: PROJECT DESCRIPTION/BACKGROUND CONTINUED LUA-06-053, PP, ECF N t Vicinity map Page 2of8 There are currently five homes and a number of accessory structures on the site, which would be removed as part of the proposal. Primary access to the lots would be from a new road, NE 2"" Pl., which would extend from Duvall Ave. NE through the site and loop down, as Field Ave. NE, to connect with NE 2"" St.. A smaller loop of road would provide public access for Lots 5 through 20. Lots 9, 10, 15, 16, 34, 35, 38, 39, 48 and 49 would be accessed via 20 ft. wide access easements. The applicant has asked the City to grant a modification to reduce the required right-of-way width of the public streets from 50 ft. to 42 ft., which would include 32 ft. of paving, and curbs, gutters and sidewalks. Street improvements to Duvall Ave. NE and NE 2"" St. will be required along the frontage of the site. A 30 ft. wide unused right-of-way easement extends along the east property line starting at the north property line. It makes up a significant portion of Lots 15 through 20 and the larger of the two drainage tracts. The easement was placed by owners of the property at a time when the land was previously subdivided under King County jurisdiction. The previous subdivision was never constructed. The area in the easement is no longer necessary for right-of-way, because the new design for subdivision of the property provides a different pattern of public access through the site. For this reason, the easement will be released at the time the final plat is recorded. A very small segment of that 30 ft. wide strip located at proposed Lot 20 is actual right-of-way, which must be vacated prior to recording of the plat. The applicant has contacted the City and the vacation is in process. There is a Class 4 stream just east of the site, near Lots 48, 49 and Drainage Tract B, which the applicant is proposing a 25 ft. reduced buffer for. This reduction from the required 35 ft. is allowed by the critical areas regulations if the vegetation consists of native vegetation with less than 5% invasive species. There is also a Category 2 wetland to the east of the site, near proposed Lots 15 and 16. The 50 ft. buffer of this wetland would extend over the corner of Lot 15. There is a Category 3 wetland on the parcel to the north, which extends very slightly into proposed Lots 3 and 4. The portion of this wetland on the neighboring lot has been filled and the small remaining part is unregulated due to its size. The site is relatively flat. The soils at the site are Alderwood gravelly sandy loam. The applicant proposes clearing and grading for the roads, lots, utilities and detention pond. An estimated 4,500 cy of soil will be excavated and then used as fill on the site so there would be a balance of cut and fill. The site vegetation consists of residential landscaping and approximately 250 significant trees. The applicant has proposed to retain approximately 60 significant trees. The applicant has submitted a conceptual landscaping plan showing two new trees in the front yard of each lot. IIPART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21 C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations.

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 is nearly flat, the steepest slopes being 8%. A geotechnical report prepared by Earth Solutions NW, LLC, dated April 13, 2006, was submitted with the land use application. The surface soils are mapped as Alderwood gravelly sandy loam. The applicant proposes grading for site preparation and road construction. The applicant anticipates approximately 4,500 cy of cut and 4,500 cy of fill, with no soil leaving or being brought to the site. The geotechnical engineer concludes that the existing soils are suitable for the proposed development of single-family homes and infrastructure. It is recommended that construction take place during the drier summer months. with additional measures required if construction is proposed during the wet season. ERC Report Magnusson City of Renton P/8/PW Department MAGNUSSEN PRELIMINARY PLAT Envir mtal Review Committee Staff Report LUA-06-053 PP ECF REPORT OF September 11, 2006 Page 4 of 8 Staff recommends that the applicant shall comply with the recommendations contained within the geotechnical report prepared by Earth Solutions NW, LLC as a SEPA mitigation measure. Clearing of vegetation on the property and grading of the site in order to locate the proposed utilities, construct the proposed roadway and prepare the site for residential building pads is proposed. In the Preliminary Technical Information Report prepared by the applicant's stormwater consultant, Jim Jaeger, temporary erosion and sedimentation control is proposed. Staff recommends that the applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements, outlined in Volume II of the 2001 Stormwater Management Manual, and provide staff with a Construction Mitigation Plan prior to issuance of construction permits. Staff anticipates that if these measures and the existing code provisions are followed, stormwater and erosion control impacts would be adequately mitigated. In addition, these measures, once implemented, would ensure that neighboring properties would not be impacted by this development. Mitigation Measures: 1. The applicant shall comply with the recommendations contained in the geotechnical report prepared by Earth Solutions NW, LLC, dated April 13, 2006 under "Site Preparation and Earthwork, "Detention Pond Recommendations," and "Utility Trench Backfill." 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements, outlined in Volume II of the 2001 Stormwater Management Manual, and provide staff with a Construction Mitigation Plan prior to issuance of construction permits. This Plan shall be subject to the review and approval of the Development Services Division. Policy Nexus: SEPA Environmental Regulations; Vol. II 2001 DOE Stormwater Management Manual 2. Water -Surface Water Impacts: The applicant has provided a surface water drainage report prepared by James J. Jaeger, P.E., dated April 24, 2006. Revisions were made to the report in a supplement received from Mr. Jaeger dated August 2, 2006. The surface water plan proposes two drainage ponds, one on a corner within the subdivision and a smaller one on the southeastern edge of the plat. Water detention and water quality treatment will be provided before the system discharges into the existing public drainage system in NE 2°• St. and further south to Maplewood Creek. Staff have reviewed the proposed surface water drainage system and offsite improvements. They point out that there are known downstream flooding and erosion problems in the Maplewood Creek Basin. To avoid possible impacts to the drainage basin, they recommend that the applicant be required comply with the 2005 King County Surface Water Design Manual to meet both detention (conservation flow control) and water quality (basic) improvements. They also recommend that the applicant be required to comply with the recommendation contained in the revised drainage report, dated August 2, 2006, with regards to the re-routing of the natural discharge location of Pond B to the existing 36-inch pipe. This would bypass the Puget Colony Homes surface drainage system that had previous problems that were repaired, but could re-occur. Staff notes that the 2005 King County Surface Water Design Manual allows that projects having multiple natural discharge that recombine within a quarter mile downstream to be considered as a single natural discharge location. Mitigation Measures: 1. The applicant shall comply with the 2005 King County Surface Water Design Manual to meet both detention (conservation flow control) and water quality (basic) improvements. 2. The applicant shall comply with the recommendation contained on the Drainage Report by Jim Jaeger, P.E., revised on August 2, 2006, with regards to the re-routing of the natural discharge location of pond B to the existing 36-inch pipe. Policy Nexus: SEPA Environmental Regulations; 1990 King County Surface Water Design Manual ERC Report Magnussen City of Renton P/BIPW Department MAGNUSSEN PRELIMINARY PLAT REPORT OF September 11, 2006 Wetlands and Streams Envir ,ntal Review Committee Staff Report LUA-06-053, PP, ECF Page5of8 Impacts: The applicant has provided a Critical Areas Assessment and Delineation Report prepared by Chad Armour, LLC, dated April 14, 2006 addressing the wetlands and stream on or near the site. Staff had secondary review completed on the report by The Watershed Company and the results are contained in their letter dated June 15, 2006. As explained in the description above, there are an off-site wetland, an off-site stream and a wetland that is partially on the site in the project area. To the east of the site at the north end a small area of the 50 ft. buffer of a Category 2 wetland extends onto the site. This wetland was identified and categorized as part of the West Coast Properties Preliminary Plat LUA04-149 by Gary Schulz on October 31, 2004. The Critical Areas Assessment submitted by the applicant for the Magnussen Preliminary Plat proports that this wetland is only a Category 3, because it has been severely disturbed by recent construction of a regional stormwater system in the wetland. As such, only a 25 ft. buffer would be required, and the buffer would not extend onto the Magnussen Plat site at all. The off-site stream located just east of the site near lots 48, 49 and Tract B is a Class 4 stream with 35 ft. buffers. The applicant has requested to have the buffer reduced to 25 ft. as allowed in the stream regulations. The reduction may be granted if the buffer is extensively vegetated with native species and has less than 5% invasive species, stream and habitat functions are not compromised by the reduction and a buffer enhancement plan is included in the project. The applicant's consultant and the City's consultant agree that the buffer qualifies for the buffer reduction to 25 ft. The City's consultant recommends as part of the required enhancement plan the removal of 1) the Himalayan blackberry vines at the north and south part of the buffer, 2) the small area of ivy at the north end, south of the blackberry, and 3) the patch of bishop's hat (Epimedium spp.) in the middle section of the buffer. Because the enhancement plan is required if the buffer is to be reduced, the applicant must submit the plan prior to October 2"", 2006 so that it can be entered into the record for consideration by the Hearing Examiner. The small, approximately 65 sq. ft., portion of wetland that extends onto the Magnussen Plat site from the north onto proposed Lot 4, is a fragment of a Category 3 wetland primarily located on the site of the MB Short Plat, LUA05-060. This wetland was defined as unregulated and filled recently, leaving only an isolated remnant on the Magnussen Plat site. Because of its small size, it is considered unregulated and can also be filled. Mitigation Measures: No further mitigation is recommended. Policy Nexus: NA 3. Plants Impacts: The applicant is proposing clearing the existing vegetation on the site for construction of the new lots, utilities, streets and detention ponds. A Tree Plan and Preliminary Grading Plan was submitted with the application for review. It appears that of the approximately 250 trees on the site, approximately 60 are proposed for retention. The tree policy requires that a minimum of 25% be retained, and if this is not possible, replaced at a ratio of 1 :1, so an additional three trees would need to be designated for the Magnussen site. The trees identified for retention on the submitted tree plan must be protected from damage at all stages of site development, including site preparation, construction of improvements, and building construction. In addition to the retained trees, the vegetation in critical areas buffers must be retained. The 25 ft. buffer area of the stream at the east of the site must be placed in a Native Growth Protection Easement, which must be recorded with the final plat. The trees in the Native Growth Protection Easement do not count toward the 25% of protected trees. To lessen the impact of removing trees and other vegetation, the applicant is also required by the development regulations to plant two new trees in the front yard area of each lot of the plat and to provide landscaping along the frontage of the new lots. The area around the proposed detention ponds must also be landscaped. The applicant submitted a preliminary landscape plan illustrating the two new trees per ERC Report Magnussen City of Renton P/BIPW Department MAGNUSSEN PRELIMINARY PLAT Envir ental Review Committee Staff Report LUA-06-053, PP, ECF REPORT OF September 11, 2006 Page 6 of 8 lot, the frontage landscaping and the detention pond landscaping. A detailed landscaping plan will be required at the time of submittal for construction permits. The loss of vegetation from developing the site is reduced and mitigated by the tree retention requirement, the new tree requirement and the landscaping requirements. Mitigation Measures: No further mitigation is recommended. Policy Nexus: NA 4. Fire Protection Impacts: Fire Prevention staff indicates that sufficient resources exist to furnish services to the proposed development; subject to the condition that the applicant provide required improvements and fees. As the proposal would add 44 new residences to the City, staff recommends that the applicant be required to pay a Fire Mitigation Fee in the amount of $488.00 per new single-family residence with credit given for 5 existing residences. The total fee is estimated at $21,472 (49 new residences -5 existing residences = 44 x $488.00 = $21,472). Staff recommends that the payment of the fee be required prior to the recording of the final plat. Mitigation Measures: 1. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $488.00 per new single-family lot prior to the recording of the final plat. Policy Nexus: SEPA Environmental Regulations; Fire Mitigation Fee Resolution No. 2913, Ordinance 4527. 5. Transportation Impacts: The addition of 44 new homes to the area would result in an increase in traffic trips to the City's street system. A Traffic Impact Analysis, prepared by Gibson Traffic Consultants, dated May 2, 2006 was submitted by the applicant. The study estimates the addition of 469 additional daily trips would result from the new development, with 37 new a.m. peak-hour trips and 49 new p.m. peak-hour trips on an average weekday. The analysis states that mitigation for the new traffic will be provided by extending NE 2"" St. and Field Ave. NE through the development, providing frontage improvements to NE 2"' St. from the western boundary of the site to Field Ave. NE, and installing stop signs where traffic from the new development enters Duvall Ave. NE and also NE 2"" St.. The report notes a "partial sight restriction (tree branches) looking to the left, north on Jericho Ave. NE from NE 2"" St. stopped approach." Staff recommends that the applicant remove the tree branches and certify that any sight restriction is eliminated at the intersection of NE 2nd St. and Jericho Ave. NE. Staff also recommends as mitigation for the increased traffic volumes, that the applicant pay a Traffic Mitigation Fee based on a rate of $75.00 per new trip. Each new residence is expected to generate approximately 9.57 trips per day with credit given for 5 existing residences. For the proposal, the Traffic Mitigation Fee is estimated at $31,581 (49 new residences -5 existing residences = 44 x 9.57 trips x $75 per trip = $31,581). Staff recommends that this fee be payable prior to the recording of the final plat. Mitigation Measures: 1. The applicant shall remove the sight obscuring tree branches, noted in the Traffic Impact Analysis by Gibson Traffic Consultants, at the intersection of NE 2"" St. and Jericho Ave. NE and provide Development Services with proof of this at the time of submittal for street construction permits. 2. The applicant shall pay the appropriate Traffic Mitigation Fee based on $75.00 per each new average daily trip associated with the project prior to the recording of the final plat.

Parks & Recreation Impacts: Staff anticipates that future residents of the proposed plat will utilize City facilities, and it is anticipated that the proposed development would generate future demand on existing and future City parks, recreational facilities and programs. Staff recommends that the applicant be required to pay a Parks Mitigation Fee based on $530.76 per each new single-family lot. The fee is estimated at $23,353.44 (49 lots -5 existing lots = 44 x $530.76 = $23,353.44). Staff recommends that this fee be payable prior to the recording of the final plat. Mitigation Measures: 1.

PAGE# INDEX SECT~ September 11, 2006 Jim Jaeger Jaeger Engineering 9419 S. 2041h Place Kent, WA 98031 SUBJECT: Magnnssen Preliminary Plat (LUA 06-053) Reqnest for Modification -Street Width Reduction Dear Mr. Jaeger: We have reviewed the proposed street modi ft cation request associated with the proposed 49-lot single-family residential preliminary plat located generally on NE 2nd Street between Duvall Avenue NE and Nile Avenue NE. This is an infill development in a rapidly developing area with two proposed access points. The existing streets are substandard pavement with some pedestrian improvements. The proposed modification requests to allow the proposed new roads width be reduced to 42-feet throughout the plat with standard cross-section of32-feet of pavement, parking, curb, gutter and sidewalk on both sides. This will allow the creation ofreasonable lots within the constraints of property shape, size, storm system requirements and stream buffer. The Street Modification request is hereby approved. City Code 4-6-050 (Street Standards) requires full street improvements for all adjacent rights-of- way for, within, and dedicated by a plat. There are also certain standards for width of dedication for proposed streets to be added to the City grid. One of these is the 42-foot wide dedication with 32 feet of pavement, 5-foot sidewalk and curb, and streetlights. This allows full use of the street in normal manner. The City can modify street improvements for new plats if there are practical difficulties in carrying out the provisions of the Street Improvement Ordinance. The Modification Procedures as defined in Section 4-9-250D clearly states the criteria for approval by the department Administrator. In order for a modification to be approved, the department Administrator must, " ... find that a special individual reason makes the strict letter of this Ordinance impractical, that the modification is in conformity with the intent and purpose of this Ordinance, and that such modification: (a) Will meet the objectives and safety, function, appearance, environmental protection, and maintainability intended by this Ordinance, 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; and (e) Will not create adverse impacts to other properties in the vicinity." Jim Jaeger September 11, 2006 Page 2 Meets objectives and safety, function: Due to the physical constraints within the parcel at this location due to the stream and its buffer and connection requirements with adjacent roadways, staff supports the modification request. The intent of public and emergency access and pedestrian amenities is met with the proposal, as there is no reduction in the pavement width or sidewalks. The proposed road cross-section meets the minimum standards providing two lanes of traffic, parking, curb, gutter and sidewalks on all frontages. Not injurious or adversely impact adjacent properties: Adjacent properties are not injured nor adversely impacted as all dedications are from the proposed plat. Conforms to the intent of the code: The intent of providing for the City street network is met with the dedication and extension of NE 2"d Place and Field Avenue NE from Duvall Avenue NE to NE 2"d Street. Justified and required for use and situation intended: The modifications as requested allow the maximum density and number oflots that still meet the various setbacks and access criteria. The plat provides the minimum necessary for full use for access, emergency and domestic, as well as parking and pedestrian amenities. The Street Modification is approved. This decision to approve the proposed Street Modification is subject to a fourteen-(14) day appeal period from the date of this letter. Any appeals of the administrative decision must be filed with the City of Renton Hearing Examiner by 5:00 p.m., September 25, 2006. Appeals must be filed in writing together with the required $75.00 application fee with: Hearing Examiner, City of Renton, 1055 South Grady Way, Renton, WA 98055. City of Renton Municipal Code Section 4-8-110 governs appeals to the Examiner. Additional information regarding the appeal process may be obtained from the Renton City Clerk's Office, ( 425) 430- 6510.

Fesser :pf Magnussen Plat, LUA-06-053, PP Format and Legal Description Review Bob Mac Onie and I have reviewed the above referenced preliminary plat submittal and have the following comments: Comments for the Applicant: The Supplemental Commitment for Chicago Title Insurance Co., Order No. 001148453, dated April 18, 2006, includes a new "Paragraph 25" which mentions the right, title and interest of Beth Shewchuk, presumed by the King County Tax Rolls to have an interest in Lot 3 of King County Short Plat No. 882065, Tax Lot No. 152305-9222. New "Paragraph 26" mentions matters that may be disclosed by a search of the records against the name of the spouse of Beth Shewchuk, if married. It is not exactly clear if, or how, these two items encumber said tax lot, but if they do, they will have to be resolved prior to approval of the final plat, or the individuals will need to become signatories thereto. The preliminary plat drawing notes that a 30' X 60' strip of land, conveyed to King County under Rec. No. 8705050924 for road purposes in April 1987, is proposed for vacation. If so, then be sure to allow for sufficient time for the City of Renton street vacation process to be completed. Information needed for final long plat approval includes the following: Note the City of Renton land use action number and land record number, LUA-OX-XXX-FP and LND-10-0446, respectively, on the plat drawing sheets. The type size used for the land record number should be smaller than that used for the land use action number. Please note that the land use action number for the final plat will be different from the preliminary plat and is unknown as of this date. A licensed surveyor will need to prepare, stamp, sign and date the final short plat drawing(s). \H:\File Sys\LND -Land Subdivision & Surveying Records\l...ND-10 -Plats\0446'R.V060613.doc June 15, 2006 Page 2 Tie to the City of Renton Survey Control Network.

This is a new development with two (2) proposed access points. The modification request is rather complicated, asking for impervious surface limitations to be imposed on the residential lots, in particular Lots 1-42 draining to Pond "A" be restricted to a maximum coverage of 3300 square feet, and Lots 43-49 draining to Pond "B" be allowed a maximum of 3000 square feet. No method of enforcement was suggested. The developer has requested to be allowed to limit the maximum impervious surface per lot to control the size of the required storm water facilities serving the plat per the 2005 King County Surface Water Design Manual. This figure is below the maximum allowed by Renton City code. There is no minimum Jot coverage threshold. There is a mix of proposed housing styles and lot sizes. The square footage proposal represents the maximum impervious surface coverage to be allowed including porches, decks, pavers, or additional paving or concrete. The modification request is approved to allow final design of the pond using 3,300 square feet per lot for Pond "A" and 3,000 square feet per lot for Pond "B" with two (2) conditions: 1. A statement of covenant shall be placed and recorded both on the face of the plat and within the CC&R's for the HOA to be formed with the plat limiting the impervious coverage of the single family lots to 3,300 or 3,000 square feet in accordance with the drainage pond serving the Jot. 2. A restrictive covenant shall be recorded limiting installation within the backyard setbacks to pervious landscaping only such as grass, shrubs, and trees. This decision to approve the proposed modifications is subject to a fourteen-(14) day appeal period from the date of this letter. Any appeals of the administrative decision must be filed with the City of Renton Hearing Examiner by 5:00 p.m., September 14, 2006. _______ 10_5_5_S_ou_th_Gr_ad_y_W_ay---R-e-nt-on-,-W-a-sh-in_gt_o_n_9_8_05_5 ______ ~ AHEAD,OF THE.

The static water pressure is about 75 psi at street elevation (see Ci~ water civil drawing no. W-0943). There is also an 8-inch water main along NE 2n St that can deliver 1,250 gpm (see City water civil drawing No. W-3265). The proposed project is located outside the Aquifer Protection Area. Static pressure varies from 71 to 75 psi. Pressure Zone is 565. 3. Lots 43 to 49 are within Water District No. 90 service area. The applicant submitted a certificate of water availability from the Water District No. 90. The Certificate shows that the District's system can provide a minimum of 1,000 gpm of available fire flow. There is also an 8" sewer on Duvall Ave NE, north of the northerly property line (fronting Duvall Ave NE -drawing S-3195). There is also an 8-inch sewer main on NE 2nd Street (drawing S-3265). A storm drainage plan and drainage report in accordance to the 2005 King County Manual was provided. The applicant is proposing two detention and water quality ponds. This project drains to Maplewood Creek. There are no curb/gutter, sidewalk, fronting the site, on Duvall Ave NE, NE 2nd St and Fields Ave NE. CODE REQUIREMENTS WATER 1. A water main extension (8-inch minimum diameter) within the new streets interior to the plat will be required. 2.

New water service stuu~ to each lot must be installed in conJu .. ction with the above water main extension prior to recording of the plat. 5. Existing and new hydrants will be required to be retrofitted with Storz "quick disconnect" fittings, if not already in place. 6. The Water System Development Charge (SOC) would be triggered at the single-family rate of $1,956 per new single-family per building lot. This fee is payable at the time the utility construction permit is issued. SANITARY SEWER 1. A sewer main extension to the east property line will be required. The sewer main shall be installed at a depth that will allow sewer mains extensions to provide gravity sewer as far as possible. 2. A sewer main extension along Field Ave NE will also be required. 3. Existing septic systems shall be abandoned in accordance with King County Health prior to recording of the plat 4. These parcels are subject to the East Renton Interceptor Special Assessment District (SAD). Fees are collected at the time the utility construction permit is issued. 5.

Sonja J. Fesser J>i Magnussen Plat, LUA-06-053, PP Format and Legal Description Review Bob Mac Onie and I have reviewed the above referenced preliminary plat submittal and have the following comments: Comments for the Applicant: The Supplemental Commitment for Chicago Title Insurance Co., Order No. 001148453, dated April 18, 2006, includes a new "Paragraph 25" which mentions the right, title and interest of Beth Shewchuk, presumed by the King County Tax Rolls to have an interest in Lot 3 of King County Short Plat No. 882065, Tax Lot No. I 52305-9222. New "Paragraph 26" mentions matters that may be disclosed by a search of the records against the name of the spouse of Beth Shewchuk, if married. It is not exactly clear if, or how, these two items encumber said tax lot, but if they do, they will have to be resolved prior to approval of the final plat, or the individuals will need to become signatories thereto. The preliminary plat drawing notes that a 30' X 60' strip of land, conveyed to King County under Rec. No. 8705050924 for road purposes in April 1987, is proposed for vacation. If so, then be sure to allow for sufficient time for the City of Renton street vacation process to be completed. Information needed for final long plat approval includes the following: Note the City of Renton land use action number and land record number, LUA-OX-XXX-FP and LND-10-0446, respectively, on the plat drawing sheets. The type size used for the land record number should be smaller than that used for the land use action number. Please note that the land use action number for the final plat will he different from the preliminary plat and is unknown as of this date. A licensed surveyor will need to prepare, stamp, sign and date the final short plat drawing(s). \H:\Fi]e Sys\LND -Land Subdivision & Surveying Reconls\LN D-l O -Plats.\0446\R V0606 l 3.doc ..

The city will provide addresses for the proposed lots after the preliminary plat is approved. On the final plat submittal, remove all references to utility facilities, topog lines and other items not directly impacting the subdivision. These items are provided only for preliminary plat approval. Note encroachments, if any. Note all easements, agreements and covenants of record on the drawing.

Ownership and maintenance of said Tracts shall be the responsibility of the HOA. In the event that the HOA is dissolved or otherwise fails to meet its property tax obligations as evidenced by non-payment of property taxes for a period of eighteen (I 8) months, then each lot in this plat shall assume and have an equal and undivided ownership interest in the Tracts previously owned by the HOA and have the attendant financial and maintenance responsibilities. The new private 20' wide easements shown on the face of the plat are for the benefit of future owners of specific proposed lots. Since the new lots created via this plat are under common ownership at the time of plat recording, there can be no new easements created until ownership of the lots are conveyed to others, together with/or subject to specific easement rights Add the following Declaration of Covenant language on the plat submittal, if the previous paragraph applies: DECLARATION OF COVENANT.

This is a new development with two proposed access points. The modification request is rather complicated asking for impervious surface limitations to be imposed on the residential lots, in particular Lots 1-42 draining to Pond "A" be restricted to a maximum coverage of 3300 square feet, and Lots 43-49 draining to Pond "B" be allowed a maximum of 3000 square feet. No method of enforcement was suggested. The developer has requested to be allowed to limit the maximum impervious surface per lot to control the size of the required storm water facilities serving the plat per the 2005 King County Surface Water Design Manual. This figure is below the maximum allowed by Renton City code. There is no minimum lot coverage threshold. There is a mix of proposed housing styles and lot sizes. The square footage proposal represents the maximum impervious surface coverage to be allowed including porches, decks, pavers or additional paving or concrete. The modification request is approved to allow final design of the pond using 3,300 square feet per lot for Pond "A" and 3,000 square feet per lot for Pond "B" with two conditions: I. A statement of covenant shall be placed and recorded both on the face of the plat and within the CC&R's for the HOA to be formed with the plat limiting the impervious coverage of the single family lots to 3,300 or 3,000 square feet in accordance with the drainage pond serving the lot. 2. A restrictive covenant shall be recorded limiting installation within the backyard setbacks to pervious landscaping only such as grass, shrubs and trees. This decision to approve the proposed modifications is subject to a fourteen-(14) day appeal period from the date of this letter. Any appeals of the administrative decision must be filed with the City of Renton Hearing Examiner by 5:00 p.m., September 14, 2006. Appeals must be filed in writing together with the required $75.00 application fee with: Hearing Examiner, City of Renton, 1055 South Grady Way, Renton, WA 98055. City of Renton Municipal Code Section 4-8-110 governs appeals to the Examiner. Additional information , regarding the appeal process may be obtained from the Renton City Clerk's Office, ( 425) 430- 6510.

It is north and east of the Laurelhurst Plats. This project is in the Maplewood Creek drainage basin. The pre-application meeting comments indicated that the drainage system for this project will be subject to the 2005 King County Drainage Manual. using the Conservation Flow criteria. This criteria specifies that the pre-developed condition for the drainage calculations be considered as l 00% forest. This results in some very large pond volumes. We are agreeable to meeting this requirement. The County Drainage code also recommends that the developed site condition use 4000 SF of impervious surface per lot, or the maximum allowable impervious surface as specified by the zoning code. The City has also asked that this number be used for the developed condition. The 4000 SF number should not be used by the City of Renton for several reasons. The City zoning code does not have a specified maximum . impervious surface per lot. This removes one of the options in the County code. More importantly, the County building setbacks are much smaller than the City's setbacks (5' rear, sides, 10' front). As such; it is much easier to improve a new lot with more building and impervious surface. A few other significant notes; The City of Kent has also adopted the 2001 King County Drainage Manual. They have adjusted their code to use 3000 SF per lot for developed impervious, re~ognizing that its zoning code is different than the County's. Also, the 2005 County Manual recommends using flow control BMP's as part of the drainage system design. One of those BMP's is a restricted footprint for the house and i_mpervious surface for the lots. In this case, the final plat plan specifies limits to the impervious surface that can be developed on the lots. . I would like to request that the City allow this plat to use less than the 4000 SF of impervious surface per lot for the developed drainage design. I have developed a table that shows a proposed restricted impervious surface are for each lot in this plat. The proposed design impervious surface was developed using each lot area and its respective maximum building coverage percent based on the zoning code. (Lots over 5000 SF used max. 35% or 2500 SF. whichever is larger per zoning code). I also evaluated each lot for the maximum building coverage based on the building setbacks. This was the limit for building coverage on some of the smaller lots. I also added area for driveways (500 SF or larger lots • .400 SF for smaller lots) and area for patios and walkways. This results in a table of maximum impervious surface per lot. I addes joint driveway easements and private road easements as separate impervious surfaces. along with all of the roads. I have attached this table and the pertinent pages from the 2005 King County Manual and the City of Kent Manual. Please review and grant our request for the modification lo the drainage code. I also think ii would be prudent for the City to consider this issue since it will likely re-surface on many future projects where the 2005 County code is used. It is my belief that the 2005 County manual already allows this restricted footprint as a flow control BMP and a modification might not be necessary. Thank you for your time. Sincerely, James Jaeger.

Wickstr~ .• Public Works Director Gary Gill, P.E., City Engineer Bill Wolinski, P.E., Environmental Engineering Manager Tim LaPorte, P.E., Design Engineering Manager · Charlene Anderson, Planning Manager· Regarding: . Blanket Adjustment 2004-2 for the 2002 City of Kent Surface Water Design Manual The City of Kent has reviewed the amount of impervious surface actually being constructed on several single family developments. This has been done with the purpose of confirming that the single family lot impervious surface requirements fairly equate to real life conditions. The result of this review indicate that the amount of impervious surface being installed on single famny residential lots is less than the minimum amounts currently required to be included in the stormwater analysis by the 2002 City of Kent Surface Water Design Manual. Blanket adjustment 2004-2 revises the section on page 3-27 of the 1998 King County Surface Water Design Manual titled Calculation of Impervious Surface under section 3.2.2 KCRTS/Runoff Files Method to assume impervious surface coverage for urban residential development shall not be less than 3,000 square feet per lot or the maximum impervious coverage permitted by code, whichever is less. The section is revised to read: "Q CALCULATION OF IMPERVIOUS AREA Total Impervious Coverage Table 3.2.2.D (p.3-28) lists impervious percent coverage for use in KCRTS analysis of existing residential areas. The tabulated figures are· useful in offsite analysis that includes large developed residential areas, making a detailed survey of impervious coverage impractical. Impervious coverage for proposed residential and commercial developments must be estimated for each specific proposal. Impervious coverage of streets, sidewalks, hard surface trails, etc., shall be taken from layouts of the proposal. House/ driveway or building coverage shall be as follows: · • For urban residential development, the assumed impervious coverage shall not be les.s than 3,000 4,GOO square feet per lot or the maximum impervious coverage permitted by code (K.C.C.21A,12.030), whichever is less. · 0, ' ; Ill. OFFSITE DRAINAGE A. UPSTREAM DRAINAGE The surrounding property that is higher than the subject plat is the property to the north and the west. Duvall Ave. NE runs along the west property line. This ROW has recently been improved by the Laurelhurst plat. The improvements include curb. gutter & sidewalk and a drainage system. These improvements will intercept any flows from the west and direct them into the Laurelhurst drainage system. The property to the north is nearly the same elevation as the subject property. There is a recently constructed short plat in the northwest corner with a drainage system. The property to the east of the short plat and north of the Magnussen plat generally drains to the east, towards the wetland and creek area. I do not anticipate any off-site flows entering the site that will cause problems. B. DOWNSTREAM DRAINAGE The proposed project has 2 drainage ponds. Pond A is the larger of the two and will handle 85% of the plat. It is located just west of 1401h Ave. SE (Nile Ave. NE} and near the center of the plat. Pond Bis the smaller of the two and is located at the southeast corner of the plat. Pond A will discharge into an existing type 2 CB that is located within the 140th Ave. SE right-of-way. There is a 36" CPEP pipe that enters this CB from the north and exits to the south. There is a County constructed drainage pond just northeast of the subject plat. It appears that the 36" pipe is the outlet/overflow from that pond. It also appears that the 36" pipe may be an overflow or high flow conveyance system for the stream that is east of the plat. The 36" pipe runs due south within the 14Qth Ave. SE ROW. At 132nd Ave. SE. this ROW becomes part of an area along the eastern boundary of the Laurelhurst Div. 2 plat that was landscaped and left open as a buffer strip. The recent landscaping and retaining walls seem to have hidden some of the drainage structures within the 140 1h Ave. SE ROW. The City provided me with a generalized drainage system plan that shows the 36" conveyance system within 14Qth Ave. SE. A subsequent field inspection, with this map in hand, enabled me to find more of the type 2 structures. Based on this additional field observation, the 36" CPEP pipe continues south within the 140th Ave. SE ROW to approx. 100' north of SE 134th St. At this point, the 36" pipe turns to the southeast and runs through a xacant lot and into the cul-de-sac bulb at the west end of SE 134th St., in Puget Colony Homes subdivision. The 36" pipe then turns to the east and runs along the south side of SE 134th St. There are 2 type 2 catch basins that were found along this run. The pipe crosses 142nd Ave SE to q type 2 CB in the east shoulder of that road. The 36" pipe then turns south and runs to the south along the east edge of the road pavement. There are 7 type 2 CB's along this run, from SE 134th St. to SE 136th St. These 7 CB's were found in the field. There is also a large ditch within the east shoulder of 142nd Ave. SE that flows to the south. This ditch displayed running water during a dry period and has signs of high flows. The 36" pipe discharges into this ditch just south of SE 136th St. At this point, the ditch flows into a well-defined tributary of Maplewood Creek. Pond 8 will discharge into the existing roadside ditch along the north side of SE 132nd St. This ditch runs for approx. 100' and enters an 18" culvert that flows to the south under SE 132nd St. This culvert continues within a 12" piping system that is located in various easements within the Puget Colony Homes plat. The easement runs to the south between lots 3 & 4, then to the east behind lot 13. It then runs south between lots 12 & 13 to SE 133rd St. It then crosses SE 133rd St. to the south and runs between lots 20 & 21 and then lots 28 & 29. It then meets SE 134th St. and crosses to the south under that street. It then continues to the south between lots 36 & 37 and 44 & 45 to SE 135th St . . . There are several CB 's within the streets that are near the easement path. There are no open ditches or pipes that are visible within this easement path. However, there are previous drainage complaints that were obtained from King County that indicate incidents where a 12" pipe within this easement was repaired. At SE 1351h St., the drainage easement ends. There are no pipes, ditches or catch basins that indicate where the 12" goes. It is assumed that the 12" pipe runs to the east within SE 1351h St. and into the large drainage ditch in the east shoulder of 142nd Ave. SE. There are several type 2 catch basins within 142nd Ave SE. These CB' s were locked and unable to be opened. The 12" pipe can enter this shoulder drainage system within one of these CB's. SUMMARY The 36" downstream piping system is confirmed to bypass the Puget Colony Homes surface drainage system and it appears to be adequate to accommodate the discharge from Pond A. The surface drainage system within Puget Colony Homes appears to have had previous problems that were repaired, but may re-occur. The system is probably old and not built to current standards. Both ponds will use the King County Level 2 flow control with conservation flow standard. This will substantially reduce the flows that enter the downstream system. I would recommend that the discharge from Pond B also be piped into the 36" downstream system and bypass the Puget Colony Homes surface drainage system.

We received an addendum to the Preliminary Technical Information Report from Jim Jaeger on 7.21.2006. It was reviewed by Juliana Fries of our department, and there are few items that she says remain in question: I. Off-site drainage. The downstream analysis makes assumptions that need to be verified by the engineer. Apparently there are downstream problems (noted on the list of complaints) and more information is needed to verify that a Level 2 flow control would not aggravate them. 2. Drainage requirement calculations. The impervious area per lot is not what the 2005 KC Manual requires. For plats in the R-8 zone the manual requires 75% of the lot area to be considered in the calculations for impervious area, or 4,000 sq. ft., whichever is less. The average impervious area per lot used in the submitted calculation was 3,000 sq. ft. A code modification would be needed to allow for the reduction in impervious area. Before the project can be taken off hold, you will need to have received the modification to allow a drainage calculation based on a lower ratio of impervious area than required. You may contact Juliana Fries, the utilities plan reviewer for the project, with questions about the drainage information requirements at ( 425) 430-7278. At this time, your project remains on hold pending receipt of the requested information. Please contact me at (425) 430-7270 if you have any questions.

UPSTREAM DRAINAGE The surrounding properly that is higher than the subject plat is the properly to the north and the west. Duvall Ave. NE runs along the west properly line. This ROW has recently been improved by the Laurelhurst plat. The improvements include curb. gutter & sidewalk and a drainage system. These improvements will intercept any flows from the west and direct them into the Laurelhurst drainage system. The properly to the north is nearly the same elevation as the subject properly. There is a recently constructed short plat in the northwest corner with a drainage system. The properly to the east of the short plat and north of the Magnussen plat generally drains to the east. towards the wetland and creek area. I do not anticipate any off-site flows entering the site that will cause problems. B. DOWNSTREAM DRAINAGE The proposed project has 2 drainage ponds. Pond A is the larger of the two and will handle 85% of the plat. It is localed just west of 1401h Ave. SE (Nile Ave. NE) and near the center of the plat. Pond Bis the smaller of the two and is located at the southeast corner of the plat. Pond A will discharge into an existing type 2 CB that is located within the 14Qth Ave. SE right-of-way. There is a 36" CPEP pipe that enters this CB from the north and exits to the south. There is a County constructed drainage pond just northeast of the subject plat. It appears that the 36" pipe is the outlet/overflow from that pond. II also appears that the 36" pipe may be an overflow or high flow conveyance system for the stream that is east of the plat. The 36" pipe runs due south within the 140th Ave. SE ROW. At 132nd Ave. SE, this ROW becomes part of an area along the eastern boundary of the Laurelhurst Div. 2 plat that was landscaped and left open as a buffer strip. The recent landscaping seems to have hidden any drainage structures within the 140th Ave. SE ROW. It is assumed that the 36" CPEP pipe continues south within the 14Qth Ave. SE ROW to 136th Ave. SE. The topography of the general area would indicate that this pipe would flow to the south. I inspected the area around the intersection of SE 1361h ST. and 140th Ave. SE (projected). I did not find any drainage structures or signs of any drainage conveyance system. There is a drainage easement that runs to the east from 14Qth Ave. SE to 142nd Ave. SE, along the back of the last row of lots in the Puget Colony Homes subdivision. There is also a large ditch within the east shoulder of 142nd Ave. SE that flows to the south. This ditch displayed running water during a dry period and has signs of high flows. It is possible that the 36" pipe is directed towards this ditch within that easement. Just south of 136th Ave. SE. the ditch flows into a well-defined tributary of Maplewood Creek. If the 36" CPEP pipe continued to the south within the projected 1401h Ave. SE ROW, then it would also enter this same Maplewood Creek tributary. Pond B will discharge into the existing roadside ditch along the north side of SE 132nd St. This ditch runs for approx. 100' and enters an 18" culvert that flows to the south under SE 132nd St. This culvert continues within a 12" piping system that is located in various easements within the Puget Colony Homes plat. The easement runs to the south between lots 3 & 4, then to the east behind lot 13. It then runs south between lots 12 & 13 to SE 133rd St. It then crosses SE 133rd St. to the south and runs between lots 20 & 21 and then lots 28 & 29. It then meets SE 134th St. and crosses to the south under that street. It then continues to the south between lots 36 & 37 and 44 & 45 to SE 135th St. There ore several CB's within the streets that are near the easement path. There are no open ditches or pipes that are visible within this easement path. However, there are previous drainage complaints that were obtained from King County that indicate incidents where a 12" pipe within this easement was repaired. At SE 1351h St., the drainage easement ends. There ore no pipes, ditches or catch basins that indicate where the 12" goes. It is assumed that the 12" pipe runs to the east within SE 135 1h St. and into the large drainage ditch in the east shoulder of 142nd Ave. SE. There are several type 2 catch basins within 142nd Ave SE. These CB's were locked and unable to be opened. The 12" pipe can enter this shoulder drainage system within one of these CB's. SUMMARY The 36" downstream piping system appears to be adequate to accommodate the discharge from Pond A. The drainage system within Puget Colony Homes appears to have had previous problems that were repaired, but may re-occur. The system is probably old and not built to current standards. Both ponds will use the King County Level 2 flow control with conservation flow standard. This will substantially reduce the flows that enter the downstream system. If desirable, the discharge from Pond B can be piped into the 36" downstream system and bypass the Puget Colony Homes system. - ' ~,....), l,ff..P' .(?oa.,o ... j: .... ... , ' . .;;' -~· 4 4 - ""' .} ... -" - " ·-rr ; I I • ~; ~1 !

The list resulted in approx. 30 incidents dating back to 1985. Copies of the pertinent complaints are attached. The most recent complaint was a 1999 incident that stated that a house was settling. It was mentioned that the settling may have been caused by previous repairs to the Puget Colony drainage system. Another incident was in 1995 that was based on the drainage review for a proposed ROW vacation for a portion 1401h Ave. SE. The majority of the complaints were in 1991 after two years of heavy winter rains. The piping system within Puget Colony Homes was undersized for these events and failed in several locations. COMPLAINT MITIGATION The complaints all centered around the drainage system within the Puget Colony Homes plat. These complaints were previous to the year 2000. It is my belief that the 36" CPEP pipe within 1401h Ave. SE. was constructed after 2000 as a County project to relieve the Puget Colony drainage problem It appears that the stream east of the Magnussen plat flowed through this old system prior to the 36" pipe installation. Also, it may be a good idea to divert the discharge from Pond B from the roadside ditch that flows into the Puget Colony System and into the 36" pipe. lV.U1}J VUl}JUL (® King County IIG:mllli lllm!DIII Services ~·-I, ~ ·-·,.r.,:., S 111'1 l:1·1 D ·,:1 ,· .,, , 6:.:;Hlt''~ UC1!1 P;q-::> 4 IF.

In our June meeting here in Puget Col.ony, I agreed to get signatures from owners of two lots. !hose signatures wou1d permit County repair vehicl.ea/personne1 on the respective lots.

These signatures were obtained by me in good faith, lacki.ng ini'ormation which is readi1y avai1able to County employees, which states names and addresses of legal owners. Now, it seems, one of the signatures I obtained was not, in fact, a property owner's. With the help of Mr. Snow I got the llallle and address of the owners, sent them a registered letter expla1ning the situation, enclosed the forms to sign and instructed the.111 to re-turn them. to Mr. Snow at SWM • I recieved a call from Barbara Crosby, one of the own.era, this ai'ternoon. (The other owner is Chris Crosby; address: P.O. Box 2851, Renton, WA 9S056.) She stated that she wanted to cooperate, but did not want to eign the papers because the out!it which is installing the dra.iD:fields told her to give no one access to her property. I pointed out that the County agreed to return the property to its original. condition, and told her that if she refused to sign, she might provide a cause of action for the County or for u.s in the neighborhood. She asked to speak to someone "izr. authority." I gave her Jim Kramer's phone num.ber. · · The point of this 1.,,tter i:s to keeo you posted on the status of this matter, and to let you know that I am beginning to feel the agreement which flowered in June is rapidly beginning to ~ilt in August. • • .. - -' .. -.. .. .. ..

Thank you for your November 25, 1990 letter expressing your concerns about surface water problems on the street in fron~ of your property. The Surface Water Management Division has completed the "Yahn Drainage Study, Phase II." The first phase of this study identified all of the problems with this drainage basin and the magnituoe of those problems. The Pnase ll portion of the study identified solutions and recol!lllendations for solving these problems. The study has recommended three areas which must be addressed to solve the problem on your street: (1) to provide an adequate upstream storm- water. storage facility; [2) to increase the capacity of the drainage system in the basin; and (3) to provide erosion protection of the downstream natural chan- nel and reduce tne siltation of the Cedar River. Based on the results of the, study, the proposed solution to the flooding and erosion proble~ will require a Capital Improvement Program.{CIP) project estima~ed ~1~q.9op;. This project cannot be' started until all existing CIP j,, -{~ .?---project commitments are fulfilled. The Surface Water Management Division has a Ir commitment to design and construct Sl2,3 million in CIP projects over a five- I I I I I -;,;,i_ {'.}) year period ( 1987 -1991}. These C IP projects address serious flooding and ero- sion problems similar to the problems you are facing. All available funds are being used to address these problems and, without additional funding, your ClP project cannot be constructed in 1991. The Surface Water Management Division will consider this CIP project for fonding as part of a new five-year CIP beginning 1r. 1992. This S300,DDO project will likely oe high on the priority iist. Piease be aware, however, that there .;re unmet C!P project needs in King County estimated et over sao millfon. Given this deraand for projects, this project must be evaiua~ed along side other com- peting projects and scheduled accordingly. I I I I I I I I I I I I I I 1 ,, Mr. Benn 0. January l<, Page Two Lamb l!l9l Your request to c1ean the open ditc11es was invest:igated. The ditches appear t:O be c1ear of debris and are functioning correctly. Tne reason the area floods is due to a lack of capacity in the pipe system that connects to t11e open ditcnes. These pipe systems are on K1ng County rignt-of-way and 011 private property.

Box 2566 Renton, Washington 98056 Subject: Wetland and Stream Buffers Magnussen Preliminary Plat LUA-06-053 Renton, Washington Dear Mr. Rousso: 6500 1261 " Avenue S.E. Bellevue, Washington 98006-3941 (425) 641-9743 (425) 643-3499 (fax) chad@chadarmour.com JI'> .. l11)) ; In their May 24, 2006 letter, the City of Renton (Renton) requested that we justify reducing the width of the buffer adjacent to a seasonal Class 4 stream from the 35 foot standard to 25 feet. Renton also states that the buffer adjacent to the wetland off of the site to the east is 50 feet rather than 25 feet. The following paragraphs are our answers. Stream Buffer The standard 35 foot wide buffer of Class 4 streams may be reduced to 25 feet if: • The buffer is extensively vegetated with native trees and shrubs with less than 5 percent non-native invasives on slopes less than 15 percent; • The project includes a buffer enhancement plan; • There will be no net loss of ecological functions; and • The reduction is supported by Best Available Science. The forest within 40 feet of the stream is extensively vegetated. The overstory layer is dominated by big-leaf maple and western red cedar trees. Several large black cottonwood trees stick up higher than the canopy. Big-leaf maple saplings that grow under the overstory canopy and cascara are more or less common. The shrub layer is typically dominated by hazelnut and vine maple. Also present in the shrub layer are salmonberry, Himalayan blackberry, ocean-spray, and Indian plum. The herbaceous layer is typically dominated by sword fern and trailing blackberry. Other plant species also present in the herbaceous layer are Cascade Oregongrape, salal, and bracken. We estimated that the cover of blackberry is ±5 percent (Armour, 2006). The literature indicates that the ideal buffer width for aquatic areas varies from less than 25 feet to more than several hundred feet. The wider widths are exclusive to wildlife. The question is 'will a 25 foot wide buffer function ecologically similarly to a 35 foot wide buffer?' We think so. There would be no obvious ecological difference for water quality, hydrology, or habitat functions. Clearing the approximately one acre of trees east of the riparian buffer will have a greater impact on habitat functions than will a 10 foot reduction in width of the stream buffer. C:/Jobs/J&M/Lindberg/Letter to Renton.doc Chad Armour, LLC 06/15/06 - Critical Areas Buffers Renton, Washington & M Land Development Renton (2003) found that much of the natural buffer functions for hydrologic and water quality functions (peak flow attenuation, base flow releases, and water quality treatment) are removed from riparian buffer control by stonm drain systems. Storm water detention and water quality treatment requirements are regulated for new development and redevelopment within the City without reliance on riparian buffer function. The majority of plant material and insects that fall into streams comes from directly over or within a very short distance of the stream. Within the City of Renton urban areas, there are few if any mature trees and the potential of trees being allowed to grow to maturity and then naturally fall is remote. Most old and potentially unstable trees near developed areas are removed as hazard trees. There are no critical areas on the site that need enhancing. We understand that you are willing to fund a like valued enhancement project off of the site to meet Renton's code requirement. Wetland Buffer A forested wetland of undetenmined size is located east of the site. The overstory layer is dominated by black cottonwood, western red cedar, and red alder trees averaging more than 21 inches in diameter. The shrub layer is dominated by salmonberry, vine maple, Indian plum, and hardhack. The herbaceous layer is dominated by slough sedge, lady fern, sword fem, and bare soil. The bare soil appears to be the result of prolonged periods of standing or slow-moving water. The vegetation within 25 feet of the western edge of this wetland is relatively undisturbed and dominated by native plant species. Sometime in the recent past what appears to be a regional stormwater system (ponds) was constructed in this wetland. When the regional stormwater system was constructed in the wetland, it was diked and the stream's outlet modified. The ponds restrict the natural flow of the stream that is present in this wetland. Conclusions We conclude that you have and will comply with Renton's buffer reduction provisions. As such we support a 25 foot wide buffer adjacent to the Class4 4 stream. Among other things, the ecological functions of a 25 foot wide buffer are similar to that provided by a 35 foot wide buffer. The enhancement provision may be satisfied off of the site. Although the wetland to the east appears to function as Category 2 wetland, it meets Renton's criteria for Category 3 wetlands because it is severely disturbed. The standard buffer for Category 3 wetlands is 25 feet (Armour, 2006). References Armour, Chad, LLC. 2006. Critical Area Assessment and Delineation Report. Lindberg Preliminary Plat.

An off-site drainage description. The previously submitted off-site drainage (upstream and downstream) report was not relevant to this project. 2. Report of downstream drainage complaints. There are known drainage problems in the area. We have heard from downstream residents, on previous projects, that there are drainage problems. Since this area was very recently annexed to the City, the applicant should include a "list of complaints for the past 5 years" from King County records. This is necessary so we can be sure the system has the capacity to handle this project. 3. New drainage requirement calculations. In the submitted calculations for developed condition, the assumption is 3,000 sq. ft of impervious/lot. The King County Surface Water Design Manual specifies that impervious areas are to be either 75% of lot area or 4,000 sq. ft., whichever is less. In this case the calculations should be based of 4,000 sq. ft./lot instead of 3,000 sq. ft./lot You may contact Juliana Fries, the utilities plan reviewer for the project, with questions about the drainage information requirements at (425) 430-7278. At this time, your project remains on hold pending receipt of the requested information. Please contact me at (425) 430-7270 if you have any questions. Sincerely, Valerie Kinas!

First, we will need to see the building setback lines on a revised plat plan. Please show the lot widths on all lots, also. Lot 13 does not appear to meet the minimum lot size of 4,500 sq. ft. The buffer of the wetland offsite to the northeast of the site is 50 feet wide, not 25 feet, and should be shown on the project drawings as such. A Native Growth Protection Easement will be required over it and over the stream buffer on the southeast of the site. Is it known to the applicant, that the surface water detention facjlity must not be located in the stream buffer? The stream buffer takes up a good portion of the tract that is set aside for a detention pond. If a reduction of the required stream buffer from 35 feet to 25 feet is proposed, the critical areas consultant will need to justify this reduction according to the criteria in. RMC 4-3-0SOLSc(iv). Please submit five copies of a revised plat plan, addressing all of the issues noted above. Include ,;1lso an 8 V2" x 11" high-quality reduction of the plan. Submit one copy of the justification for the reduction of the stream buffer width. You can submit all of these things to my attention.

The study by Chad Armour, LLC shows what he has labeled a swale and ditch running from a wetland just northwest of the site through the middle of the site toward the southeast. The wetland at the northwest was filled as part of a short plat development. What I would like to know is: 1. Is there anything left of that wetland? 2. Is the swale classified correctly, or could it be a stream and/or wetland? Could you also look at the stream at the south.east of the site and tell me if it appears there are less that 5% of non-native invasive species in the buffer on the project site? If the cost of review will exceed $1,000.00, please contact me prior to r€view. I'll be out this Thursday and Friday, and back at my desk on Tuesday, May 301h.

MAGNUSSEN PLAT PRELIMINARY PLAT PROJECT NARRATIVE MAY C 4 2CC5 Rec .... The proposed Magnussen Plat is an application for a 49 lot single family residential subdivision situated on 7 existing lots with a total area of 8.37 acres. It is located on the east side of Duvall Ave. NE, between NE 2nd St. and NE 3rd St., if extended. This project will require preliminary plat approval and a SEPA determination by the City of Renton. The site is zoned R-8, residential. All of the proposed lots will be single family detached residences. The surrounding properties are also similarly zoned R-8. The site is currently has five existing residences. All of the existing houses and garages/sheds will be removed. All four of the existing houses have driveways connected to Duvall Ave. NE. and one has a driveway connection onto NE 2nd St. A recently constructed plat, Laurelhursl, is adjacent to the site, across Duvall Ave. NE to the west and across NE 2nd St. to the south. There is a small wetland at the north side of future lot #4 tho is too small to be regulated. There is an off-site wetland to the northeast that does not affect the site. There is a low-grade stream/ditch just east of the site that projects a 25' buffer onto the site. The site is flat. The steepest slope is approx. 8% near the existing driveway onto Duvall Ave. NE at the west property line. There are some similar slopes near the northeast portion of the property. The soils on the site are a fine silty sand, with some and silt loam. The site is dominated by residential landscaping many trees. There are approx. 150 trees that are spread throughout the plat. The existing drainage in the west and central portion of the site sheet flows across the property to a ditch that runs from the north to the south and then to the east, approx. in the center of the plat. The eastern portion of the plat sheet flows to the east towards the offsite wetland and ditch. There is a constructed drainage pond within the wetland area to the east that collects the runoff from all of the low areas surrounding the site. The proposed use of the property as a 49 lot residential subdivision will be consistent with the surrounding developments. All of the surrounding properties are developed, with the exception of the wetland area to the northeast. The proposed lots will range in size from the minimum of 4500 SF to a maximum of 7800 SF (including the stream buffer portion), in the R-8 zone. The density of the plat is 7.46 units per acre in the R-8 zone. Access to the new lots will be from a new internal public street that runs east/west and is connected to Duvall Ave. NE. and then turns to the south as an extension of Field Ave. NE. Field Ave. NE is currently undeveloped and will be constructed to connect to NE 2nd St., that was recently constructed as . . . .. part of Laurelhurst. Additionally, an internal loop road will be in the northern portion of the plat. These new streets are proposed to be 32' wide residential streets with a 42' right-of-way. The reduced ROW will be wide enough to accommodate the street and sidewalks on both sides. The reduced ROW width is needed to keep the net plat area at a maximum to stay under the maximum density. Four joint driveways will be placed within easements and will be used to access 2 lots each. Duvall Ave. NE is currently improved on the west side (by Laurelhurst) but not on the east side. The proposed plat will construct the east side of the street to complete the full road section. A new water main and sewer main will be installed in the new plat streets. The water main will be looped through the site. The eastern portion of the site, east of Field Ave NE, will be serviced by King County Water District #90. The finished lots are estimated to be worth approx. $170,000 for a total value of approx. 3.5 million dollars. The value of the lots with preliminary approval only is estimated to be $8.3 million dollars. The site will require minimal grading for the proposed road. The building pads for the lots will also require some minor grading but nothing over 2 feet. The main grading activity will be associated with the excavation for the detention ponds. The estimated amount of grading is 5120 CY for cut and 320 CY for fill. It is anticipated that the site will use some of the cut material on-site, but the majority may be exported off site if it is unsuitable for on-site fill. There are numerous trees on the site. There are approx. 150 trees on the site. Most of the trees will need to be removed due to conflicts with the roads, utilities and building pads. Land that will be dedicated to the City include the internal public roads and the drainage pond tracts. The lots will be sold by the developer to one or several builders or investors. The future builders will likely use model homes and temporary job trailers. MAGNUSSEN PLAT PRELIMINARY PLAT CONSTRUCTION MITIGATION DECRIPTION The Magnussen Plat preliminary plat is a 49 lot residential subdivision located on the east side of Duvall Ave. NE. It is anticipated that the construction of the plat will begin in the spring of 2007 and continue through the fall of that same year. The construction of the houses will likely begin in the late winter, early spring of 2008. The house construction will likely continue for approx. 1 year. depending upon the local demand for housing. The construction will occur from 7:00 AM to 6:00 PM, Monday through Friday and possibly on Saturday. If work is to be outside of these hours, previous approval will be received from the City. The proposed hauling and construction traffic routes will be along 1-405 to the Maple Valley highway interchange. The traffic will then proceed north on Sunset Ave. and turn east on NE 4th St., up into the Renton Highlands area. The traffic will then turn south on Duvall Ave. NE and proceed south on Duvall Ave. NE for approx. 'h mile to the site. Construction that occurs during the dry summer period can produce dust. This will be controlled using water trucks. Impacts to traffic will be regulated by having a traffic control plan approved by the City for work within the existing ROW. The tracking of dirt and mud will be reduced by constructing a quarry spoil construction access point as one of the initial construction items of development. MAY C 4 2006 I . .

C:/Jobs/J&M/Lindberg/Assessment Report.doc Chad Armour, LLC 1 04/14/06 • Critical Areas Assessmen' · d Delineation Renton, Washington SUMMARY OF FINDINGS & M Land Development All but a few square feet of the 8.3-acre Lindberg Preliminary Plat are upland. A small wet area (-65 square feet) is located on the site. Most of this wet area extends off site the north and appears to be a part of a stormwater management system. It appears that this wet area is not regulated as a wetland by the City of Renton (Renton). A forested wetland east of the site meets Renton's criteria for Category 3 wetlands. A seasonal stream flows through this wetland. It appears that this wetland was incorporated into a regional stormwater management system. When ponds were constructed in this wetland, the wetland was diked and the stream outlet modified. This wetland's 25-foot wide buffer does not encroach on the site. The stream mentioned in the previous paragraph meets Renton's criteria for Class 4 waters. The minimum buffer for Class 4 waters is 25 feet. SITE DESCRIPTION The 8.3-acre site is the location of several single-family dwellings, mowed lawn, gardens, and forest. It is located east of Duvall Avenue NE in Section 15, Township 23 North, Range 5 East, in Renton, Washington (Figure 1). It is bounded by a temporary storage facility and the BM Short Plat to the north, a mature forest to the east, and single-family homes to the south and west. Elevation on this relatively level site ranges from 390 to 406 feet above mean sea level (Center Pointe Surveying, 2005). A shallow swale crosses a part of the site. It terminates in a shallow ditch that is connected to the regional stormwater system previously described (Figure 2). BACKGROUND INFORMATION The following sections of the report present information about the planned development, wetlands, streams, soils, and precipitation. Planned Development We understand that you are considering constructing as many as 49 single-family residences on the site. To do so, you intend to demolish the existing structures. Critical Areas We reviewed existing available reports and maps to assess the potential for wetlands and streams to be present on or adjacent to the site. The site is located in the Cedar River/Lake Washington watershed and Lower Cedar River drainage basin (King County, 2006). Wetlands The National Wetlands Inventory (NWI) does not show any wetlands on or near the site (FWS, 2005). The King County (County) iMap for the area in the vicinity of the site shows an 11-acre wetland (No. 31150) present on and off site to the east (King County, C:/Jobs/J&M/Lindberg/Assessment Report.doc Chad Armour, LLC 2 04/14/06 Critical Areas Assess men· d Delineation Renton, Washington , & M Land Development 2005). Renton's sensitive areas map indicates that a wetland similar to that shown on the County map is mapped on and adjacent to the site (Renton, 2004). Streams Neither the NWI nor United Stated Geological Survey (USGS, 1994) topographic maps show any streams on or near the site. The County iMap shows an unclassified stream located east of the site. This stream is shown to flow through Wetland 31150. Renton's sensitive areas map also shows this stream. Soils There is one soil type mapped on the site; Alderwood gravelly sandy loam 6 to 15 percent slopes (Figure 3). Alderwood soils are made up of moderately well drained soils underlain by a dense till layer typically two to 3.5 feet below the surface. Alderwood soils formed in glacial deposits under conifer trees. Till is a barrier that retards the downward percolation of the rain that falls on the soil. When the soil above the till layer becomes saturated, water that accumulates on the till surface will pool in depressions or flow in the direction of the gradient. The general subsurface flow is ultimately concentrated in depressions or streams. The erosion hazard for Alderwood soils on gentle slopes is moderate (Snyder et al., 1973). Alderwood gravelly sandy loam is not a listed hydric soil (NRCS, 1995). Precipitation In March 2005, the day before we first visited the site, 0.14 inch of precipitation was recorded at Seattle-Tacoma International airport (NOAA, 2005). The previous 40 days were uncharacteristically dry. In contrast January 2006 was very wet and the following two months were somewhat dry (NOAA, 2006). EXISTING CONDITIONS We visited the site on March 17 and September 23, 2005 and April 13, 2006 to check for the presence of wetlands and streams on and in the vicinity of the site. On-Site Conditions The site is generally characterized by environmental conditions typical of western Washington upland plant communities. Uplands We characterized a small stand of immature trees on parcel number 152305-9206. At this location the site is dominated by Douglas-fir and big-leaf maple trees in the overstory layer (Table 1). These trees average somewhat less than 18 inches in diameter (dbh) (range 13 to 22 inches dbh). The mid-story is dominated by big-leaf maple saplings. Six different shrub species are present in the shrub layer, but none dominate. The herbaceous layer is dominated by sweetscented bedstraw. Not one of these plant species is a hydrophyte (Appendix A -Plot ID SP-2). At this location the soil resembles the soil mapping unit, Alderwood gravelly sandy loam. The first 4 inches of the soil profile is duff. The next 14+ inches of soil is described as dark yellowish brown C:/Jobs/J&M/Lindberg/Assessment Report.doc Chad Armour, LLC 3 04/14/06 Critical Areas Assessmen d Delineation Renton, Washington & M Land Development (10YR 4/4) gravelly sandy loam with no hint of mottles. In March 2005 the soil to a depth of more than 18 inches was moist. We characterized the forest in the southeast corner of the site ion September 2006. Here the overstory layer is dominated by big-leaf maple and western red cedar trees. Several large black cottonwood trees stick up higher than the canopy. Big-leaf maple saplings that grow under the overstory canopy and cascara are more or less common. The shrub layer is typically dominated by hazelnut and vine maple. Also present in the shrub layer are salmonberry, Himalayan blackberry, ocean-spray, and Indian plum. The herbaceous layer is typically dominated by sword fern and trailing blackberry. Other plant species also present in the herbaceous layer are Cascade Oregongrape, salal, and bracken. Where we observed the soil, the surface layer is black (10YR 2/1) gravelly silt loam over very dark grayish brown (1 OYR 3/2) gravelly sandy loam. There was no hint of hydrology in this slight depression (Plot ID SP-3). We characterized the swale that crosses a part of the site because it supports two very small (<20 square feet) areas of slough sedge -an obligate wetland plant species. In general the swale is either characterized by bare soil or a thick tangle of Himalayan blackberry canes. The soil is best described as 11 inches of black (1 OYR 2/1) gravelly sandy loam over more than 9 inches of grayish brown (2.5Y 5/2) gravelly sandy loam with many, coarse, faint mottles. As noted on our field data form, the bare soil is not a result of prolonged standing water. We encountered saturated soil 6 inches below the ground surface (Plot ID SP-1). The remainder of the site is characterized by mowed lawn, gardens, and ornamental plantings. Wetlands A very small area (-65 square feet) of land with wetland characteristics is located on the site (Figure 2). Most of this wet area extends off site the north. It appears that a significant portion of this wet area was excavated to serve as a stormwater management system. In April 2006 we observed that the part of this wet area on the adjacent property to the north (BM Short Plat) had been cleared. Based on the map posted on the sign in front of this plat, this portion of the wet area will be converted to single-family homes. As such we assume that this area is not regulated as a wetland by Renton. Off~Site Conditions One wetland, an area with wetland characteristics, and a stream are located near the site. Wetlands A forested wetland of undetenmined size is located east of the site (Figure 2). Although the County inventory indicates that this wetland covers 11 acres, it is likely that it covers far less area because their map shows it extending on to the site (it does not). Based on a single measurement, we estimate that this wetland is about 80 feet wide east to west. Sometime in the recent past what appears to be a regional stormwater system (ponds) C:/Jobs/J&M/Lindberg/Assessment Report.doc Chad Armour, LLC 4 04/14/06 Critical Areas Assessmen• ~nd Delineation Renton, Washington J & M Land Development was constructed in this wetland. The ponds restrict the natural flow of the stream that is present in this wetland. It appears that someone else delineated the edge of the wetland east of the site within the last two or more years. It is dominated by an overstory layer of black cottonwood, western red cedar, and red alder trees averaging more than 21 inches in diameter. The shrub layer is dominated by salmonberry, vine maple, Indian plum, and hardhack. The herbaceous layer is dominated by slough sedge, lady fern, sword fern, and bare soil. The bare soil appears to be the result of prolonged periods of standing or slow-moving water. The vegetation within 25 feet of the western edge of this wetland is relatively undisturbed and dominated by native plant species. There appear to be no wetland dependent wildlife species present in this wetland. Although our functional assessment suggests that this wetland exhibits moderate wetland functions (Appendix B), it meets Renton's criteria for Category 3 wetlands because it is severely disturbed. When the regional stormwater system was constructed in the wetland, it was diked and the stream's outlet modified. The standard buffer for Category 3 wetlands is 25 feet (Renton, 2005). What appears to be a stormwater pond is located north of the BM Short Plat. This wet area is dominated by black cottonwood trees that average 18 inches dbh (range 12 to 24 inches). Growing beneath the cottonwood canopy are patches of hardhack and soft rush. The linear wet area that extends south of this basin is dominated by shrubs (willow and red alder saplings, and hardhack) and soft rush. As mentioned previously, a portion of this wet area has been cleared and is planned for development on the adjacent BM Short Plat. Streams A seasonal stream is located east of the site and flows through the wetland to the east. After passing through ponds, the stream flows along the eastern boundary of the site (Figure 2). The stream was dry at the time of our September 2005 site visit. It held standing water during our April 2006 site visit. We assume that it flows during the winter rainy season following prolonged periods of rain. It is unlikely that it supports salmonids. This stream flows into another stream before discharging to the Cedar River. Based on Renton regulations, the stream appears to meet the criterion for Class 4 waters. The buffer for Class 4 waters is 35 feet. The buffer for Class 4 waters can be reduced to 25 feet (RMC-L5Civ). REGULATORY CONSIDERATIONS Renton adopted new wetland and stream regulations in 2005. Wetlands Among other things Category 3 wetlands are severely disturbed. Severely disturbed wetlands are characterized by: • Hydrologic isolation; • Human-related hydrologic alterations such as diking, ditching, channelization, and/or outlet modification; C:/Jobs/J&M/Lindberg/Assessment Report.doc Chad Armour, LLC 5 04/14/06 Critical Areas Assessme,· · · d Delineation Renton, Washington • The presence of fill, soil removal and/or compaction; and • The vegetation that may have been altered (RMC-M1aiiia). & M Land Development It is assumed that the functions of Category 3 wetlands cannot be fully protected unless their buffers are fully vegetated with native vegetation. Otherwise a wider buffer may be required. Where disturbance has occurred, revegetation with native vegetation may be required (Renton, 2005). Streams . Class 4 waters are non-salmonid-bearing water courses that flow intermittently during years with normal rainfall (RMC-L 1 aiv). CONCLUSIONS All but a tiny fraction of the 8.3-acre Lindberg site is upland. A very small wet area is present on the site. This wet area appears to be a part of a stormwater management system. The on-site portion of this wet area is mowed lawn. A forested wetland and seasonal stream are located east of the site. The wetland meets Renton's criteria for Category 3 wetlands because it has been severely disturbed. The 25-foot wide buffer does not encroach on to the site. The stream meets Renton's criteria for Class 4 waters. The minimum buffer width for Class 4 waters is 25 feet.

After we arrived at the site, we traversed the area in and around the proposed development to look for indicators of wetlands. We used the Routine On-site Determination method detailed in the U.S. Army Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987) and Washington State Wetlands Identification and Delineation Manual (Ecology, 1997). We identified plant species using the Flora of the Pacific Northwest (Hitchcock and Cronquist, 1973) and A Field Guide to the Common Wetland Plants of Western Washington and Northwestern Oregon (Cooke, 1997). The associated indicator status for each plant species was determined using the National List of Plant Species That Occur in Wetlands: Northwest [Region 91 (Reed 1988, updated in 1993). We reviewed City of Renton (2005) regulations to assess applicable issues associated with wetlands and streams. Soils were identified using the Soil Survey of King County Area, Washington (Snyder et. al, 1973). We used the Natural Resources Conservation Service Hydric Soils of the United States list to determine if the soils mapped on the site are hydric (NRCS, 1995). We marked the location of sampling points, wetland boundary, stream centerline, and the swale/ditch centerlines with a unique identifying number on pink-colored flagging. Others flagged the boundary of the wetland located east of the site. Following our site visit, Centre Pointe Surveying fixed the location of the flagged wetland boundaries (including a portion of the wetland located east of the site flagged by others), stream centerline, swale/ditch centerline, and sampling points. Brick Tudor Studios produced the figures. The location of the sampling points, wetlands, streams, buffers, and the swale/ditch system are shown on Figure 2. Wetland detenmination and wetland rating forms completed by Chad Anmour are presented at the end of this appendix. Indicator categories shown on the field data forms are defined as follows: OBL (obligate) >99% FACW (facultative wetland) 67% -99% FAC (facultative) 34% -66% FACU (facultative upland) 1 % -33% UPL (upland) <1% NI No Indicator Assi ned A positive or negative sign more specifically defines the regional frequency of occurrence for FACW, FAC, or FACU species. A positive sign(+) indicates a frequency toward the higher end of the category. Conversely, a negative sign(-) indicates a frequency toward the lower end of the category.

EROSION CONTROL I. OVERVIEW The proposed Magnussen Plat is an application for a 49 lot single family residential subdivision situated on 7 existing lots with a total area of 8.37 acres. It is located on the east side of Duvall Ave. NE, between NE 2nd St. and NE 3rd St., if extended. This project will require preliminary plat approval and a SEPA determination by the City of Renton. The site is zoned R-8, residential. All of the proposed lots will be single family detached residences. The surrounding properties are also similarly zoned R-8. The site is currently has five existing residences. All of the existing houses and garages/sheds will be removed. All four of the existing houses have driveways connected to Duvall Ave. NE. and one has a driveway connection onto NE 2nd St. A recently constructed plat, Laurelhurst, is adjacent to the site, across Duvall Ave. NE to the west and across NE 2nd St. to the south. There is a small wetland at the north side of future lot #4 tha is too small to be regulated. There is an off-site wetland to the northeast that does not affect the site. There is a low-grade stream/ditch just east of the site that projects a 25' buffer onto the site. The site is flat. The steepest slope is approx. 8% near the existing driveway onto Duvall Ave. NE at the west property line. There are some similar slopes near the northeast portion of the property. The soils on the site are a fine silty sand, with some and silt loam. The site is dominated by residential landscaping many trees. There are approx. 150 trees that are spread throughout the plat. The existing drainage in the west and central portion of the site sheet flows across the property to a ditch that runs from the north to the south and then to the east approx. in the center of the plat. The eastern portion of the plat sheet flows to the east towards the offsite wetland and ditch. There is a constructed drainage pond within the wetland area to the east that collects the runoff from all of the low areas surrounding the site. Access to the new lots will be from a new internal public street that runs east/west and is connected to Duvall Ave. NE. and then turns to the south as an extension of Field Ave. NE. Field Ave. NE is currently undeveloped and will be constructed to connect to NE 2nd St., that was recently constructed as part of Laurelhurst. Additionally, an internal loop road will be in the northern portion of the plat. These new streets are proposed to be 32' wide residential streets with a 42' right-of-way. Four joint driveways will be placed within easements and will be used to access 2 lots each. Duvall Ave. NE is currently improved on the west side (by Laurelhurst) but not on the east side. The proposed plat will construct the east side of the street to complete the full road section. The site will require minimal grading for the proposed road. The building pads for the lots will also require some minor grading but nothing over 2 feel. The main grading activity will be associated with the excavation for the detention ponds. The estimated amount of grading is 5120 CY for cut and 320 CY for fill. It is anticipated that the site will use some of the cut material on-site, but the majority may be exported off site if it is unsuitable for on-site fill. There are numerous trees on the site. There are approx. 150 trees on the site. Most of the trees will need to be removed due to conflicts with the roads, utilities and building pads. Land that will be dedicated to the City include the internal public roads and the drainage pond tracts.

Discharge at Natural Location: The existing site currently sheet flows across the property to the existing central ditch and lo the offsite ditch to the east and to the wetland offsite to the northeast. There is a public drainage system within the ROW for 140th Ave. SE (Field Ave. NE) that consists of catch basins, large piping, man holes and a storm drain main. The proposed drainage system will collect the runoff into the pond located at the southeast property corner and discharge it into the existing ditch to the east. A second, larger pond will be located near the center of the east property line and discharge into the existing drainage system within Field Ave NE. This is the same drainage system into which the existing site runoff discharges. 2. Off-Site Analysis: An upstream and downstream drainage analysis has been performed and is detailed in section Ill of this report. 3. Runoff Control: This project is providing a 2005 King County level 2 standard flow control, with conservation flow control criteria. This matches storm duration for the half 2 year through the 50 year storm event. It matches peak flows for the half 2 year event. The conservation flow criteria requires using the historic ground surface conditions, which is forest cover with no existing impervious surface. The flow control will be accomplished using a detention pond with an orifice type flow restrictor. 4. Conveyance System: The project will provide conveyance piping for the street drainage and the lot roof downspouts. The piping will be sized to handle the 100 year developed storm event. 5. Erosion and Sedimentation Control Plan: An erosion control plan will be prepared and will be included with the engineering plans. This erosion control system will include silt fencing along the east and portions of the north and south property lines, construction entrance, seeding & mulching and clearing limits. A sediment pond will be designed as part of the initial grading and development of the site. 6. Maintenance and Operation: The improvements to this site will dedicated to the City and will be maintained by the City. The private driveways and drainage piping will be maintained jointly by the applicable lots. - 7. Bonds and Liability: The appropriate bonding and insurance forms will be secured prior to any construction on the site. SPECIAL DRAINAGE REQUIREMENTS There are 12 special drainage requirements that may apply to any project. In this case, none of them apply to this project. Ill. OFFSITE DRAINAGE A. UPSTREAM DRAINAGE There is no upstream off-site drainage tributary area for this project. The highest property line is along the the east property line. Along the east property line is an existing subdivision and street (Harrington Place NE). This street has a CB & piping drainage system that intercepts any runoff from the east and directs it to the north within the public ROW. The existing lots along the east property line are drain to Harrington Place. · Some rear yards may drain to the subject site, but this runoff is minimal. The south and north property lines also have small lot subdivisions. These property lines are generally at the same elevation as the subject site and would not flow onto the site. The west property line is the Edmonds Ave. ROW and is the low portion of the site. B. DOWNSTREAM DRAINAGE The drainage from the site will be discharged from the detention pond near the southwest property corner and into a new 12" conveyance pipe that will run approx, 50 west. across Edmonds Ave. NE and into an existing type 2 catch basin. This type 2 CB is listed as CB #8,B5-2 in the City inventory. This CB is located west of the road centerline. in the southbound lane of the street. The catch basin is approx. 9' deep. This CB outlets into an 18" concrete pipe that runs north within Edmonds Ave. NE for 390 ft. to another type 2 CB (#8,B5-1 ). This CB is also within the road pavement, located west of the centerline. This CB is at the intersection of NE 22nd St. This CB discharges into an 18" concrete pipe that runs to the north within Edmonds Ave. NE for 300 ft. to type 2 CB (8,84-4), at the intersection of NE 23rd St. This CB discharges to the north within an 18" concrete pipe, running lo the north for 200 fl. to type 2 CB (8,B4-2). at the intersection of NE 23rd Place. This CB discharges to the north within an 18" concrete pipe that runs for 250 ft. to type 2 CB (8,84-3), at the intersection of NE 24th SI. This CB discharges to the north within an 18" concrete pipe for 347 ft. to a type 2 CB (8,B3-2) at the intersection of NE 25 1h St. All of the upstream catch basins are west of the centerline. within the pavement. This CB discharges to the north within an 18" concrete pipe for 574 ft. and into a type 2 CB (8,B2-1 ). This CB is located at the intersection of NE 27th St. The improved portion of Edmonds Ave NE ends at this point. This is located at the top of the steep slopes down to May Creek, just west of the confluence with Honey Creek. This CB discharges into May Creek, but the pipeline mechanism was not observed in the field that runs into the Creek. May Creek is approx. 2400 ft. downstream from the subject site. With the King County level 2 detention requirement in place for this project, the developed runoff from the site should not have an impact on the downstream drainage system. I understand that the level 2 requirement is a result of problems within the May Creek Basin. IV. PREDEVELOPED DRAINAGE The drainage from the existing site currently sheet flows towards the existing central ditch and the offsite ditch to the east and offsite wetland to the northeast. The on-site ditch flows from the north to the south, in the center of the property and then to the east. It discharges into a catch basin in the Field Ave. NE ROW that then carries the drainage to an existing pond in the wetland area to the northeast. The existing site area is characterized by lawn, toll grass and shrubs, with many trees throughout the site. In addition to the central ditch, there ore several culverts within that ditch path and numerous small yard drains and small diameter piping within the site. The existing frontage along Duvall Ave. NE is half improved with the west half being constructed by the Laurelhurst Plat. This plat will construct the east half. The entire site area of 8.36 acres was used as the tributary drainage basin, plus the% rood frontage for Duvall Ave. NE, the ROW area for Field Ave. NE and the% ROW for NE 2nd St. The total project area was determined to be 8.89 acres. There will be two detention ponds on this project. The area will be split into sub-basins to match the tributary areas for each pond. The conservation flow control criteria was applied. This requires that the pre-developed ground condition be 100% forest. The existing drainage analysis was performed using the "KCRTS" hydrology software and its summary tables and charts ore attached for reference. The methods outlined in the 2005 King County Surface Water Drainage Manual were used as guidelines. Following this page are the data sheets used for the computer input data. The computer summary sheets for peak flow and time of concentration calculations are also attached.

DEVELOPED DRAINAGE The developed project will include two new detention ponds & wetponds. One will be located at the southeast corner of the site. The larger pond will be located just west of the Field Ave. NE ROW, south of NE 2nd Pl. Both will be located within a drainage tracts that will be landscaped as recommended by the City. The site drainage will be routed into the ponds using catch basins and pipes located within the new roads. Each new lot will be furnished with a piped drainage stub that will be connected to the street drainage system or with a pipe in the rear yards of the lots. The areas used to calculate the flows were the same as those areas used in the predeveloped drainage calculations. The detention pond was sized to meet the performance criteria established by the King County Level 2 detention standard. This criteria is that the pond can only release at a rate not to exceed 50% of the 2 year pre-developed peak flow while retaining 50% of the 2 year developed peak flow. This is the same for the 25 year peak flows. Additionally, the storm event duration for the developed site conditions must match are be less than the pre-developed storm duration, for the 50% of the 2 year flow through the 50 year storm flow. This is the level 2 standard as specified in the 2005 King County Manual. A wetpond will be used to meet the water quality standards. The wetponds will utilize the detention pond areas and will provide the required dead storage below the detention live storage. The volume for the dead storage is based on the area of the impervious and pervious surfaces that drain into the pond. Similar to the existing condition, the KCRTS method was used to determine the peak flows for the various storm events. A duration curve comparison was performed to evaluate the vault performance. The computer data sheets for the developed flows follow this page as well as the works sheets and the time of concentration calculations. A brief summary of the developed drainage characteristics are: POND A: 2 year peak flow: 10 year peak flow: 100 year peak flow: total area: pervious area: ground cover: impervious area: ground cover: 1.41 CFS 1.69 CFS 2.85 CFS 7.59 acres 2.81 acres till grass 4.78 acres impervious PONDB 2 year peak flow: 10 year peak flow: 100 year peak flow: total area: pervious area: ground cover: impervious area: ground cover: 0.20 CFS 0.24 CFS 0.41 CFS 1.13 acres 0.49 acres till grass 1.64 acres impervious f\f:f;. cy ' ' :,..._ 4. ,re- ' i) ~ ~ l ,.

The City's concerns are the impacts of proposed residential development on the City street system; specifically, NE 4th Street and signalized intersections at Duvall Avenue (138th Avenue SE) and Jericho Avenue (144th Avenue SE). This technical memorandum summarizes the following elements: existing 2006 and future 2008 Level of Service (LOS) analysis for weekday PM peak traffic conditions at these off-site intersections; local/plat access intersections on Duvall and Jericho Avenues; traffic generation and distribution; operational saftety impacts; and, recommended mitigation measures for the proposed residential development. PROPOSED SITE DEVELOPMENT & ACCESS The proposed Magnussen Plat development is located along the east side of Duvall Avenue opposite NE 2•d Place in the City of Renton (see Figure 1). The site is currently vacant and extends to NE 2nd Street to the south and east of Field Avenue NE. The proposed residential development would build 49 new single-family detached (SFD) homes on the site. The proposed development is scheduled for construction and full occupancy by the year 2008. For the traffic/LOS analysis, 2008 was used for the future horizon year. Site access to the majority of the SFD lots would be provided via an improved NE 2 00 Place plat access road which would connect Duvall Avenue to the west with Field Avenue to the east. Access to lots in the southeast corner of the plat would be provided via 2nd Street and 140th Avenue. A proposed Site Plan has been included in the attachments.

GTC obtained new weekday PM peak period turning movement (TM) counts at 4th/Duvall intersection using All Traftic Data on April 13, 2006. Existing PM peak turning movement counts at 4th/Jericho intersection were obtained in April 2003 for the Jericho Plat TIA study. These TM counts were used to assess existing peak operating conditions at the study intersections. Existing 2006 PM peak turning volumes are summarized in Figure 2. The baseline traftic volumes were determined by utilizing a 2.0% annually compounded growth rate to the horizon year of 2008. The future with development traffic volumes were determined by adding the development's traffic volumes to the baseline traffic volumes. One pipeline project (Jericho Plat, with 37 single-family detached units) has also been included in baseline traffic volumes. Traftic to be generated by the Magnussen Plat site has been estimated using trip generationdata published in the Institute of Transportation Engineers'(ITE) Trip Generation manual, 7th edition. Based on existing travel patterns (from TM counts) and employment and retail destinations in the site vicinity, GTC estimated the likely trip distribution of site traffic to the adjacent City road system. Level of Service Traftic congestion is generally measured in terms of level of service (LOS). Peak-hour level of service at critical off-site intersections was determined using the methodology described in the 2000 Highway Capacity Manual (HCM). In accordance with the Manual, road facilities and intersections are rated between LOS A and F, with LOS A being free flow and LOS F being forced flow or over-capacity conditions. The level of service criteria is listed in Table 1. The level of service at signalized intersections is based on the average delay of all approaches. At unsignalized intersections, level of service is based on the worst/highest delay for all intersection movements or approaches. Geometric characteristics and conflicting traftic movements are taken into consideration when determining level of service values. Per City of Renton standards, the required threshold for satisfactory intersection LOS is 'D' or better. Level of Service (LOS) analyses have been performed for PM peak traffic conditions at all study intersections requested during scoping process. Peak-hour level or service (LOS) determinations at study intersections were made using the methodology described in the 2000 Highway Capacity Manual (HCM), TRB Special Report 209 and Synchro software (version 6). Terry Gibson, responsible for the traffic analysis and report, is a licensed professional engineer (Civil) in the State of Washington and past-President of the Washington State section ofITE. Ms. Kayren Kittrick May 2, 2006 Page 3 EXISTING CONDITIONS Street System & Traffic Control The street system in the vicinity of the project site is shown on Figure 1. Site access for the Magnussen Plat residential development would be provided via NE 4th Street, Duvall Avenue and Jericho Avenue to the surrounding area. Access to proposed SFD homes would be provided by NE 2nd Place, Field Avenue NE and NE 2nd Street. NE 4th Street is a five-lane, east-west arterial with a center two-way-left-tum-lane provided and a posted speed limit of 35 mph. NE 4th Street connects to NE 3rd Street to provide access to downtown Renton west ofI-405. There is curb, gutter, sidewalk and landscape sections along the length of NE 4th Street on the north side of the road. On the south side along site frontage, a 7-foot paved shoulder is provided. King County Metro provides transit service along NE 4th Street via bus routes 105 and 111 express, with bus stops provided at Duvall and Jericho Avenue signals. Duvall Avenue NE, which would provide primary access to the subject site, is a City local access street south of 4th Street and is an arterial north of 4th and connects to Coal Creek Pkwy. South of 4th Street Duvall Avenue is a two-lane roadway with curb/gutter section and sidewalk on the west side and 5-foot paved shoulder on the east side. The posted speed limit is 25 mph near site vicinity. However, to the north of 4th Street, Duvall Avenue is a five-lane, north-south arterial road with a center two-way left-tum lane with curb/gutter and sidewalk sections on both sides. The posted speed limit is 40 mph. Jericho Avenue NE would provide secondary access to the subject plat and, is a City local access street that dead-ends north ofNE 4th Street. Jericho Avenue has two (2) travel lanes plus a third lane provided on the road approaches to the 4th Street signalized intersection. The posted speed limit is 30 mph for this City road, and no curb/gutter sections or sidewalks are provided in the project vicinity. NE 2•d Place is a two-lane local access street west of Duvall Avenue and provides access to the Laurelhurst neighborhood. The existing pavement width is 32 feet with curb/gutter and sidewalk sections provided on both sides. East of Duvall Avenue, 2nd Place is a narrow private roadway with a pavement width of 12 feet. NE 2nd Street is a two-lane local access street which connects Duvall and Jericho Avenue. 2nd Street has a 22-24 foot pavement width with variable gravel shoulders and is posted for 25 mph. Ms. Kayren Kittrick May 2, 2006 Page4 Existing Traffic Volumes OTC obtained a new weekday PM peak period turning movement count (by All Traffic Data) on Ajril 13, 2006 at the 4th/Duvall intersection. The PM peak turning movement count at the 4 /Jericho intersection was obtained from Jericho Plat TIA memorandum (OTC, February 3, 2004). Figure 2 depicts existing PM peak-hour turning movement volumes at the study intersections. Assuming a typical 'k' factor (peak-to-daily volumes) of 10 %, NE 4th Street presently carries 23,500 vehicles daily on an average weekday (A WDT) west of Duvall Avenue. Duvall Avenue handles about 12,600 AWDT north of 4th Street and only 1,700 A WDT south of 4th toward the project site. Jericho Avenue presently carries about 7,000 A WDT south of 4th Street. The capacity of 5-lane arterials is 30,000 A WDT while 2-lane roadways with paved shoulders have a carrying capacity of about 12,000 A WDT. 4th Street is operating at about 80% of its capacity and Jericho Avenue at about 60% of capacity. South of 4th Street, Duvall Avenue has low traffic volumes at present with 15 % of capacity. Existing Level of Service (LOS) Conditions Traffic flow and congestion on roads and highways is usually measured in terms of level-of- service (LOS) at critical intersections. Traffic flow varies from LOS A free-flow conditions to LOS F forced-flow conditions, with LOS E representing capacity conditions (see Table 1). For signalized intersections, the level of service is determined by the average delay per entering vehicle on all approaches. Using the methodology described in the 2000 Highway Capacity Manual and software package from T rafficware Synchro 6/Build 610 for signalized intersections, OTC calculated the existing LOS and average stopped delay at each study intersection.For existing peak traffic conditions, the 4th Street/Duvall Avenue intersection operates at LOS D with 41.7 seconds of average delay. The signalized intersection of 4th Street at Jericho Avenue operates at LOS C with 30.8 seconds of average delayas summarized in Table 2. FUTURE TRAFFIC CONDITIONS Trip Generation Trip generation estimates for the proposed residential development is based on natonal research data for similar land nses contained in the Institute of Transportation Engineers' (ITE) Trip Generation, 1h Edition (2003). ITE Land Use Code 210 has been used for residential units. Average trip generation rates have been utilized for estimating daily and AM/PM peak trips for the proposed single-family homes. For the proposed 49 SFD homes at the Magnussen Plat an estimated 469 ADT with 37 AM peak-hour trips (9 inbound/28 outbound) and 49 PM peak- hour trips (31 inbound/18 outbound) would be generated on an average weekday. Table 3 summarizes the trip generation results for the proposed Magnussen Plat development. Ms. Kayren Kittrick May 2, 2006 Page5 Trip Distribution Based on the existing travel patterns (from TM counts) and employment and retail destinations in the site vicinity, GTC estimated the likely trip distribution of site traffic to the adjacent City/State road systems. All site traffic would utilize the NE 4th Street arterial for access to the project site. It is anticipated that 35% of site traffic will travel to/from west on 4th Street toward I-405 with 30% on Duvall Avenue/Coal Creek Pkwy north toward Bellevue and the remaining 35% east on 4th Street. Detailed trip distributions for daily and PM peak trips are included in Figure 3. Background Traffic, Pipeline & Horizon Year The baseline and future with development level of service (LOS) analyses have been performed at all study intersections. The baseline traffic volumes were determined by utilizing a 2% annual compounded growth factor to the horizon year of 2008. One pipeline project (Jericho Plat, with 37 single-family detached homes) south of 4th Street between Hoquiam and Jericho Avenues has been included in the 2008 baseline traffic volumes. Note: A horizon year of 2008 has been selected for the traffic analysis, when the proposed SFD homes are expected to be fully occupied. The baseline PM peak-hour turning movement volumes used for the future 2008 LOS analysis are shown in Figure 4 for study intersections. The future with development traffic volumes were · determined by adding the development's traffic volumes to the baseline traffic volumes. The future with development turning movement volumes used for the future with development LOS analysis are shown in Figure 5. Peak-hour level of service (LOS) determinations at study intersections were made using the methodology described in the 2000 Highway Capacity Manual (HCM), TRB Special Report 209 and Synchro software (version 6). Baseline Level of Service (2008) Under the baseline traffic scenario, the 4th Street/Jericho Avenue signalized intersection would degrade from LOS C to LOS D. With the addition of background growth and pipeline trips, the signalized intersection of 4th Street at Duvall Avenue will experience increase in delay but will continue to operate at LOS D. A summary of the intersection levels of service for baseline trips scenario has been included in Table 4. Future with Development LOS (2008) With the addition of project trips, 4th Street/Duvall Avenue and 4th Street/Jericho Avenue intersections will experience increases in delays but will remain at LOS D or the same service levels as for baseline conditions. A summary of the intersection levels of service with project trips scenario has been included in Table 4. Ms. Kayren Kittrick May 2, 2006 Page6 Site Access, Channelization Needs & Safety Issues As mentioned earlier, the majority of site traffic would utilize the new NE znd Place (plat accessroad) to be constructed between Duvall Road and Field Avenue. Access to lots 34-42 would be provided via NE znd Street, with access to lots 43-48 from 140lh Avenue (see Preliminary Plat map). NE znd Place would be constructed to City design standards with a 32- foot pavement plus curb/gutter and sidewalk sections on both sides. NE znd Street has been improved on the south side west of 140th Avenue and has a 24-foot pavement east of 140th to Jericho Avenue. Field Avenue would be widened to a 32-foot roadway with curb/gutter and sidewalk sections on both sides between NE znd Street and NE znd Place. Projected 2008 PM peak-hour turning volumes at access intersections would be minor (less than 25 vph) and would not warrant channelization improvements (separate left-tum and right-tum lanes on Duvall Avenue or Field Avenue at NE znd Place. GTC performed sight distance assessments at the critical site access locations on Duvall and Jericho Avenues to assess visibility for entering/exiting site traffic to/from the subject plat. The posted speed limit on Duvall Avenue is 25 mph with an assumed design speed of 30 mph. AASHTO design standards require a minimum stopping sight distance (SSD) of 200 feet and entering sight distances (ESD) of 335 feet and 290 feet for left and right-tum exit movements, respectively. To the north and south of acess location, both entering and stopping sight distances exceed 600 feet. Jericho A venue has a speed limit of 30 mph, with ESD requirements of 390 and 335 feet for left/right-tum exit movements assuming a design speed of 35 mph. There is a partial sight restriction (tree branches) looking to the left/north on Jericho Avenue from the znd Street stopped approach, but approaching vehicles remain in the view of sight and safe exiting movements can occur at this intersection. The view to the right/south is clear for over 600 feet which easily satisfies AASHTO sight distance requirements. MITIGATION Off-Site Mitigation (City of Renton) The City of Renton has established traffic mitigation fees of $75 per new average daily trip (ADT) generated by developments. The estimated weekday daily trips for this project is 469 ADT, which for this proposed development would result in a total mitigation fee of $35,175. On-site Acess & Frontage Improvements The following on-site access, roadway and frontage improvements are recommended to provide adequate/safe site traffic access to the proposed residential development and to enhance vehicular/pedestrian travel safety in the site vicinity: Ms. Kayren Kittrick May 2, 2006 Page 7 • Construct new roadway improvements for NE 2nd Place per City ofRenton's road design standards, with a 32-foot pavement width plus curbs/gutters and 5-foot concrete sidewalks on both sides. • Construct frontage improvements on the north side of NE 2nd Street from the west boundary to Field Avenue NE, including curb/gutter and 5-foot sidewalk sections. • Construct new roadway and extension of Field Avenue north of NE 2nd Street to NE 2nd Place to provide access to lots 40-49. • Install standard "STOP" signs (Rl-1 per MUTCD) on the proposed westbound approach of NE 2nd Place to safely control exiting site traffic onto Duvall Avenue. A stop sign should also be installed on the Field Avenue southbound approach to NE 2nd Street. We trust that GTC's traffic analysis, report and attachments adequately address the traffic impacts of the proposed Magnussen Plat residential development, so that the City of Renton can complete its SEPA review of the proposed residential plat development.

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

The density range required in the R-8 zone would be a minimum of 4.0 to a maximum of 8.0 dwelling units per acre (du/ac). The method of calculating net density is as follows: A calculation of the number of housing units and/or Jots that would be allowed on a property after critical areas and public rights-of-way and legally recorded private access easements are subtracted from the gross area (gross acres minus public streets, easements and critical areas multiplied by allowable housing units per acre). Required critical area buffers and public and private alleys shall not be subtracted from gross acres for the purpose of net density calculations. Lindberg Preliminary Plat -Pre-Appli1 Marcl1 23, 2006 Page 2 of 6 Meeting The applicant has indicated that the net density will be 6.79 du/ac. This is based on the required deductions of the right-of-way and private access easements of totalling 60,149 sq ft from the gross site area of 361,814 sq ft .. It appears the density would be within the range of the minimum of 4.0 du/ac to the maximum of 8.0 du/ac for the R-8 zone. All square footages of areas to be deducted (i.e. public rights-of-way and private access easement) must be provided at the time of formal land us~ application in order to accurately determine density. Development Standards: The R-8 zone permits one residential structure/unit per lot. Detached accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet in size. Minimum Lot Size. Width and Depth -The minimum lot size that would permitted in the R-8 zone is 4,500 sq. ft. for parcels greater than 1 gross acre and 5,000 sq. ft. for parcels less than 1 acre-gross. The site is greater than one (1) acre-gross; therefore, a minimum lot size of 4,500 sq. ft. (net area) would be required. Lots appear to meet the 4,500 sq. ft. requirement. Please provide net square footage for lots containing access easements. A minimum lot width of 50 feet for interior lots and 60 feet for comer lots, as well as a minimum lot depth of 65 feet, is also required. For the fonmal land use application, all lots must be fully dimensioned to detenmine compliance. Building Standards -The R-8 zone would allow a maximum building coverage of 35% of the lot area or 2,500 square feet, whichever is greater for lots 5,000 square feet in size or greater. Lots less than 5,000 square feet in size would permit a maximum building coverage of 50% of the lot area. In the R-8 zone, building height is restricted to 30 feet and two stories. Detached accessory structures must remain below a height of 15 feet and one-story with a gross floor area that is less than the primary structure. Accessory structures are also included in building lot coverage calculations. Square footages of buildings to remain, if any, must be provided at the time of fonmal land use application. Also, any buildings that are to be removed/demolished must obtain a demolition permit and be removed and inspected prior to recording the final plat. Setbacks -Setbacks are the minimum distance required between the building footprint and the property line or private access easement. The required setbacks are 15 ft. for the primary structure and 20 ft. for attached garages accessed from the front yard in the front, 20 ft. in the rear and 5 ft. on interior side yards. The side yards along a street setback is 15 ft. for the primary structure and 20 ft. for the attached garages which access from the side yard along a street. All setbacks are to be shown on the formal land use application plat plan submittal, but must be removed prior to final plat recording. No setbacks were shown on the pre- application submittal. Access/Parking: Access to lots would be via either directly to public streets or via private access easements or tracts. Lot 34 and 38 would have a joint driveway from NE 2nd Street, Lots 9-1 O and Lots 15-16 would have access from easements extending from NE 2nd Place, and Lots 46-47 would have a joint driveway extending from 1401h Ave. SE. Lindberg Preliminary Plat -Pre-Appli( March 23, 2006 Page 3 of6 Meeting The applicant has requested that an unused section of 140th Ave. SE right-of-way will be requested for use as part of the lots located on the west side of that right-of-way. The applicant must either petition the City Council for a right-of-way vacation, or show the right-of-way as outside of the proposed project boundary. Lots may not include existing right-of-way. The site plan should be revised appropriately. If the subject lots do not meet minimum lot size and/or other requirements of the R-8 zone once the right-of-way area is subtracted, the lot layout will need to be further revised for consistency with code requirements. Private streets are allowed for access to six or fewer lots, with no more than 4 of the lots not abutting a public right-of-way. The street is to include a minimum easement width of 26 feet with 20 feet of paving. Private driveways may serve a maximum of two lots and must have a minimum easement width of 20 feet with 12 feet of paving. Private streets and private driveways are easements. The land area of the easement is to become part of the abutting lots. Each lot is required to accommodate off street parking for a minimum of two vehicles per lot. In addition, appropriate shared maintenance and access agreement/easements will be required between lots with shared access. Addresses of lots along private streets/driveways are to be visible from the public street by provision of a sign stating all house numbers and is to be located at the intersection of the private street and the public street. Significant Tree Retention: A tree inventory and tree retention plan shall be provided with thefh formal land use application. The plan must show preserya!jnn of at !east 25% of significant trees [those with a minimum diameter of 8" /evergreen) or 12" (deciduous) when measured four . , feet above grade], and indicate how proposed building1ootprints will be sited to accommodate j 1 preservation of significant trees. '-> ,...,. ,,,__ Landscaping and Open Space: For plats abutting non-arterial public streets, the minimum off-~ v.J-k,_J site landscaping is a five (5 ft.) wide irrigated or drought resistant landscape strip provided that if -_:;;f....-t there is additional undeveloped right-of-way in excess of 5 ft., this also must be landscaped. For : ;:. 4'). + plats abutting principal, minor or collector arterials, the width increases to 10 ft. unless otherwise ~ determined by ihe reviewing official during the subdivision process. ...:, ,to ...U,;\;..,,.I Tree requirements for plats include at least two (2) trees of a City approved species with a 50 •• j. Q,l'/'- minimum caliper of 1 Y, inches per tree must be planted in the front yard or planting strip of i,,FF'1 every lot prior to building occupancy. A conceptual landscape plan must be provided with the formal land use application as prepared by a registered Landscape Architect, a certified nurseryman or other certified professional. Sensitive Areas: The City's Critical Areas Maps indicate the presence of wetlands north of the site. Wetlands and/or buffer areas may also exist on the site. The applicant is required to submit a complete wetland report and delineation prior to formal land use application. The report must include an area extending 100 ft from the property lines of the subject site. The conclusions of the wetland report may affect the number of lots possible on the subject site. For wetlands present, the applicable buffer widths based on the category of the wetland are required (Category 1 -100 ft.; Category 2 -50 ft.; and Category 3-25 ft.). Please refer to RMC 4-3-050.M. for additional regulations on wetlands. The site is located within the City's Aquifer Protection Area Zone 2. If more than 100 cubic yards of fill are proposed, a Source Statement is required for each source location from which imported fill will be obtained. ,.. e._-e,;,,\ ".o-'Q..d '2-e..s ~ s.,,[ ve.-' ~ ho ( Lindberg Preliminary Plat • Pre·Applic March 23, 2006 Page 4 of 6 Meeting Environmental Review: The project will require SEPA review due to the number of lots of the proposed plat (greater than four dwelling units). The proposal would be brought to the Environmental Review Committee for review as it is their charge to make threshold determinations for environmental checklists. Typically, mitigation of impacts is accomplished through fees related to issues such as transportation, fire and parks as well as measures to reduce impacts to environmental elements such as wetlands, water quality, erosion, etc. Maintenance of Improvements: A homeowner's association or maintenance agreement shall be created concurrently with the recording of the final plat in order to establish maintenance responsibilities for all shared private improvements of this development (e.g., streets, landscaping, fencing and tracts). A draft of the document(s) shall be submitted to the City of Renton Development Services Division for review and approval by the City Attorney and Property Services section prior to the recording of the final plat. Permit Requirements: The project would require Preliminary Plat review and Environmental (SEPA) Review. With concurrent review of these applications, the process would take an estimated time frame of 12 to 16 weeks. After the required notification period, the Environmental Review Committee would issue a Threshold Determination for the project. When the required two-week appeal period is completed, the project would go before the Hearing Examiner for a recommendation to the City Council on the Preliminary Plat. The Hearing Examiner's recommendation, as well as the decision issued by the City Council, would be subject to two- week appeal periods. The application fee would be $2,000 for the Preliminary Plat and Y, of full fee for SEPA Review (Environmental Checklist) which is dependent on project value: less than $100,000 is $200 (1/2 of $400.00 full fee) and project value over $100,000 is a $500.00 fee (1/2 of $1000.00 full fee) plus first class postage per mailing label required for notification to surrounding property owners within 300 feet of the site. Estimated fees for the land use applications is $2,500.00. The applicant will be required to install a public information sign on the property. Detailed information regarding the land use application submittal requirements is provided in the attached handouts. Once Preliminary Plat approval is obtained, the applicant must complete the required improvements and dedications, as well as satisfy any conditions of the preliminary approval before submitting for Final Plat review. The Final Plat process also requires City Council approval. Once final approval is received, the plat may be recorded. The newly created lots may only be sold after the plat has been recorded. Fees: In addition to the applicable building and construction permit fees, the following mitigation fees would be required prior to the recording of the plat. • A Transportation Mitigation Fee based on $75 per each new average daily trip attributable to the project; and, • A Fire Mitigation Fee based on $488 per new single family residence • A Parks Mitigation Fee based on $530. 76 per new single family residence. Consistency with the Comprehensive Plan: The site would potentially be designated as Residential Single Family (RSF) per the Comprehensive Plan Land Use Map. The proposed preliminary plat generally appears to comply with the following objectives and policies: Lindberg Preliminary Plat -Pre-Applic-Meeting March 23, 2006 Page 5 of 6 Land Use Element Objective LU-FF: Encourage re-investment and rehabilitation of existing housing, and development of new residential plats resulting in quality neighborhoods that: 1. Are planned at urban densities and implement Growth Management targets, 2. Promote expansion and use of public transportation; and 3. Make more efficient use of urban services and infrastructure. Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Policy LU-149. Lot size should exclude private sidewalks, easements, private road, and driveway easements, except alley easements. Policy LU-150. Required setbacks should exclude public or private legal access areas, established through or to a lot, and parking areas. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. Policy LU-153. Interpret development standards to support plats designed to incorporate vehicular and pedestrian connections between plats and neighborhoods. Small projects composed of single parcels and/or multiple parcels of insufficient size to provide such connections, should include future street stubs. Future street connections should be clearly identified to notify residents of future roadway connections. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. Community Design Element Objective CD-D: New neighborhood development patterns should be consistent with Renton's established neighborhoods and have an interconnected road network. Policy CD 15. Land should be subdivided into blocks sized so that walking distance are minimized and convenient routes between destination points are points are available. Policy CD-16. During land division, all lots should front on streets or parks. Discourage single- tier lots with rear yards backing onto a street. Street Network Objective T-A: Create a comprehensive street system that provides reasonable vehicular circulation throughout the City while enhancing the safety and function of the local transportation system. Lindberg Preliminary Plat -Pre-Appli March 23, 2006 1 Meeting Page 6 of 6 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. Policy T-13. Provide a balance between protecting neighborhoods from increased through traffic while maintaining access to neighborhoods. New Development Policy CD-17. Development should be designed (e.g. building orientation, setbacks, landscape areas and open space, parking, and outdoor activity areas) to result in a high quality development as a primary goal, rather than to maximize density as a first consideration. Policy CD-18. Projects should only be approved at the upper end of density ranges when the following criteria are fully addressed in project level submission. a. Trees are retained, relocated, or planted to create sufficient vegetative cover to provide a landscape amenity, shade, and high quality-walking environment in an urban context. b. Lot size/configuration and lot coverage is sufficient to provide private recreation/outdoor space for each resulting lot. c. Structures can be sited so that entry, window, and door locations create and maintain privacy on adjoining yards and buildings. Architectural and landscape design should: • Prevent window and door openings looking directly into another structure, • Prevent over-reliance on fencing, or • Prevent projections of building elements into required setbacks in a pattern that reduces provision of light, visual separation, and/or require variances of modification of standards. Density may be reduced within the allowed range to bring projects into compliance with these criteria. Housing Element Policy H-16. Encourage home ownership opportunities affordable to moderate income households G. Variety of Housing Types and Regulatory Measures for Affordability Objective H-G. Allow the construction of a variety of housing types affordable to low, moderate, and middle-income households when site plans and subdivisions address maintaining the quality of neighborhoods. Policy H-40. Support projects including subdivisions and site plans incorporating innovative lot and housing types, clustered detached houses, clustered semi-attached houses, and varied lot and housing types within a site. Policy H-41. Support projects that incorporate quality features, such as additional window details, consistent architectural features on all facades, above average roofing and siding, entry porches or trellises where innovative site or subdivision designs are permitted. r Printed: 05-04-2006 Payment Made: CITY OF RENTON 1055 S.
