File #19-100931-00-VO; CITY RESPONSE LETTER To LA_NrD USE & PROPERTY LAw Denchik Wedand Violation — 35935 Pacific Highway South, Federal Way (APN: 292104-9020) This letter responds to the objections in your letter regarding the processing and evaluation of your clients' wedand violation and the gation required by the City of Federal Way to restore the de amagd areas. On September 9, 2019, the Community Development Department received correspondence from you regarding your clients' Pavid and Elizaveta rLiz'] Denchik) property violation at 35935 Pacific Highway South ("subject property") composed of two separate parcels, for unauthorized clearing, grading, and "development"' in a wetland and wedand buffer. Impacted wetlands and wedand buffers are associated with theNV,ater Resources Inventory Area 10 (WRIA 10) and the West Hylebos Creek that runs north to south through the rear of the subject property. The subject property is located wid-iin an area recognized as a sensitive regional ecological resource, surrounded by city -owned conservation properties (tax parcel #292104- 9087). AccordingIv. long term wetland protection is the foremost objective in remedying the current violations. M On August 27, 2019, the city sent review comments on the Denchiks'wetland delineation and restoration plan with a request to submit a revised critical area study with responsive information by September 26, 2019, You have responded with a letter raising four objections to this request: 1. The Denchiks were unaware ("had not the slightest notice of actual wetland boundaries and buffer boundaries") of the presence of critical areas (wetland/stream) and critical area buffers on and within 225-feet of the subject property and therefore, they cannot be held responsible for violating the city, state, and federal wetland codes in impact areas. Z The D enchiks' reside in non -conforming structure/ development, and on a non- conforming subject property, and thus, should be exempt from complying with the city's critical areas ordinance Federal Way Revised Code (FWRC) 19,145 "Environmentally Critical Areas." Further, the Denchiks should be exempt from building permit review to repair an existing sagging deck and construct a new four -foot retainina wall 1 "Dave/6pmWowans ...any human -caused &,wge to land whether at, above, or below ground or water level: and any use, or change in use, of farad whether at, above, or below grottod or water level... Development also include,-,, but is not lirnited to, filling, grading, paving, dredging, excavation, mining, drilEng, bulkheadiag; driving of piling; placing of obstructions to any right of public use; and the storage of equipment or materials." (FWRC 19.050.040) Doc, LD, 79683 19-100931-00-VO Ms. Jane Koler Page 2 of 4 3. The City of Federal Way violated due process by not providing notice of regulatory requirements to your clients, or an active development permit application. 4. The Denchiks' are being assessed fees greater than notified of and assumed to be the result of the city's consultant engaging in unauthorized reconnaissance work on the abutting lot also owned by the Denchiks at 35929 Pacific Flighway South, Federal Way, WA, 98003 (parcel #292104-9098). After review of these objections the city dete'ffiines that they do not exempt the Denchiks' from their responsibility as the property owners to correct the violations of iflegal activities on the site stated. Each of your objections are addressed below: Your first objection, repeated numerous times in the letter we received, is your clients' alleged lack of knowledge regarding wetlands and associated buffers on their property. Ignorance of a particular condition does note ' ate an owner's responsibility to meet code. Furthermore, on November 27, 2017, David Denchik sent an email to the city's Planning Inquiry email while conducting preliminary research on purchasing the subject parcels under common ownership, which he now owns, from Mr. Barovic asking, among other questions; "Does the cio have any documents or wetlandstudies that would more or less indicate the boundaries of the Hylebos wetland. The seller has stated that there is no wetland, orsensifive biolo ,gical area on the property and that the wetland terminates to the north of the parcel 2921049098. " The Planning Division sent Mr. Denchik an email response on November 27, 2017, stating that wetlands -Wd§.u_i *-n #r associated buffers of uy, to 225 feet and included a screenshot of the city's Critical Areas Map in relation to the two parcels he was interested in purchasing. Mr. Denchik met with city Planner Margaret Clark and followed up with an email providing a prelin-dnary site reconnaissance map prepared by Soundview Consultants (December 8, 2017). The map shows wetlands and associated buffers across the two parcels of interest. A follow up email from Mr. Denchik to Margaret Clark on December 14, 2017, again indicated he was aware of wetlands in the vicinity of his two parcels of interest. These facts explicitly show your clients were aware of existing wetlands and associated buffers on their properties. Your clients willingly chose to engage in development, clearing, and grading with full knowledge of the potential of existing wetlands and buffers leading to the violations incurred. Your second objection identifies that your clients reside in a non -conforming structure on a non -conforming development and should be exempt from the city's critical areas ordinance. The city recognizes the non- conformance of your clients' structures. However, the existence of non -conforming structures and sites do not exempt an owner from responsibility for the violation and associated need for mitigation actions. The actions your clients have taken to add structures, such as an unpermitted retaining wall, and the unperrilitted clearing and grading throughout the site violate FWRC 19.30.180 and FWRC 19.30�01 0(3), "Prohibition on increasing nonconformance." Your clients beo gan to expand the non-conformance of their site withut obtaining permits and pursuant to FWRC 19.30.050, any non-conformance that was illegal when initiated must be immediately brought into conformance with city code. 19-i00931-00-VO Doc. LD 79683 Ms. Jane Koler Page 3 of 4 N*vember 15,2019 Cons truction work and clearing/grading without permits violates city code, and has increased the non- conformance of the structures and sites owned by your clients. The only development permit submitted for either of your clients' properties is a building permit after they were issued the notice of violation for unpermitied clearing and grading. The construction of a rerathing wall to repair a -sAM, nonconf4rmIng deck" does not meet FWRC Reino " and additions to existing 19.145.110(5), "Normal MaififeMmce and Rd�,It6c6nsttuctirirl�br 000g. strueturesthatdo"titic �e jfieprey�approvedbuilding footprint The fooTh'ht of the deck can be r built foot iiiit and 6iere re, is not considered Your obiectioh that the� city violated� the DencliiW due proce�s is unsdbStaildate& The retl4iferhonts to n sate ■ i�� to work coo,peratTrely Varougn IF co� nOt viogteyptir clientsl�"e process.

The fourth objection that your clients are assessed fees greater than first indicated assumes the fee results from the city's consultant engaging in unauthorized reconnaissance work at the .rear area. The two parcels (3292104-9090 and 292104-9020) are considered one subject property, with the front portion of the property visible from the street. Your clients' extensive violations were identified by the city's consultant, Pertect, hic., while reviewing aerial photos during a routine desktop review, which is best management practices for professional wetland scientists throughout the state. Your clients' two parcels appear in the images used to evaluate the extent of your clients' violations. The identification of violations by the city's consultant is not an additional charge billed to your clients, but in fact part of the $4,747.00 total peer review costs, The city per pitted your dient to deposit the first half of the estimate detailed in that letter to reduce the upfront cost, financial responsibiliq, as reques Led in a meeting and by a second bill of $2,373.to fulf ill fill your clients' total lay your client with the city as outlined in the enclosed correspondence sent to the Denchiks' on May 23, 2019.

Recently, they have had some confusing encounters with the City of Federal Way about a 1960s-era home on their property located at 35929 Pacific Highway South. City officials have indicated to my clients that they are obligated to mitigate and restore wetlands and wetland buffers, and post bonds to secure mitigation work. Although the City claims that the Denchiks have violated wetlands and wetland buffers, entirely missing from the City's analysis is that neither the Denchiks nor their predecessors have ever engaged in any development activity resulting in the delineation of wetlands and wetland buffers on their property. Hence, they had no notice of the existence of wetlands or wetland buffers on their property. Further, the City has failed to consider that the Denchiks own a nonconforming home that was constructed in about 1960, long before incorporation of the City of Federal Way, and long before the City identified and regulated wetlands. Despite the fact that the alleged wetlands are located in nonconforming areas that the Denchiks have been using as part of their front and back yards, the City demands wetland restoration, but wetlands have never been identified in a development process on the Denchik property; they were, accordingly, without notice of the existence of wetlands in their front and back yard areas. The most fundamental requirement of due process in the context of enforcing laws is providing notice of regulatory requirements. Here, there was never a development process resulting in the identification and delineation of wetlands and wetland buffers. The City improperly alleges that Denchiks are violating wetlands and wetland buffers, and imposing costly restoration requirements on them, when the Denchiks had not the slightest notice of actual wetland boundaries and buffer Robert "Doc" Hansen, Planning Manager September 4, 2019 Page 2 of 3 boundaries on their property. In fact, Mr. and Mrs. Denchik were merely maintaining the yard areas of their 1960s home. The City claims they illegally constructed a retaining wall; but they constructed a wall under four feet tall, exempt from building permits. This wall supports their existing 1960's deck — they were repairing their Baggy, nonconforming deck. The City also claimed that the Denchiks were impermissibly maintaining a driveway that has existed since the 1960s. The City is alleging that the Denchiks have done illegal filling and grading within a wetland area. But, once again, no delineation was ever done indicating that Denchiks' front and back yards were located within critical wetland areas or their buffers. Denchiks' house and yard areas are nonconforming spaces established long before the City regulated wetlands and wetland buffers. The City did not adopt its first Critical Areas Ordinance until about 1999. Washington law accords strong protection to nonconforming uses and structures. And the City's own wetland ordinance recognizes exceptions allowing the maintenance of existing structures and landscaping. See FWMC Chapter 19.30; See VanSant v. City of Everett, 69 Wn.App. 641, 849 P.2d 1276 (1993). City consultant Perteet was hired by the City to do peer review of a Soundview restoration plan. But the City recently billed the Denchiks for unauthorized, extra work performed by Perteet. The Denchiks had agreed to pay the City $2,373.50 for Perteet to come to the east portion of the property to confirm a restoration plan developed by Soundview Consultants. But, Perteet entirely failed to address the Soundview restoration plan that pertains exclusively to the eastern area of the Denchik property. On a separate lot that Denchiks own that is west of the restoration area identified by Soundview, the Perteet ecologist took it upon himself to examine a parcel which was not in any way connected with the Soundview restoration plan on the east part of lot 9020. Then, Perteet, after failing to do peer review of the Soundview plan, demanded more money from the City and the City passed along that bill to my clients. The City had told Denchiks that their sole liability for payment to Perteet would be $2,373.50. Denchiks should not be charged for unauthorized reconnaissance work performed by Perteet on an abutting lot which was unrelated to the Soundview restoration plan. Mr. and Mrs. Denchik want to resolve these issues with the City in an amicable manner. Rather than throwing the book at Denchiks when they had no notice of two wetlands and wetland buffers existing within the front and back yard areas of their 1960s house, it would make sense to recognize their unequivocal right to maintain existing yard areas and existing nonconforming structures. The City should recognize a reasonable use exception; they have an absolute right to continue using and maintaining their 1960s improvements as well as their front and back yards. They Robert D• -t, September 4 Page • ' should also be allowed to maintain their existing driveway to preserve their right to safe access to State Route 99, which has four lanes of traffic and a speed limit of 50 mph. Safe access to SR 99 is crucial to the safety of the Denchiks. The City needs to recognize a reasonable use exception. Please call me to discuss this matter. We are seeking a practical solution to this problem which recognizes the right of the Denchiks to reasonable notice of wetlands on their property, which have been part of their front and back yard areas since the 1960s, and the necessity of recognizing and protecting their nonconforming right to use existing improvements and yard areas on their property.

The subject parcel is located west of Pacific Highway South and just southwest of S 359' Street in Township 21 North, Range 4 East, Section 29 NW quarter. The subject parcel has been divided into two distinct and geographically separate subparcels. The City retained Perteet to assess the type and extent of critical areas and buffer clearing, fill, and development on the subject parcel and neighboring tax parcel 292104-9163. This neighboring parcel is owned by the Lakehaven Utility District. The City also requested Perteet to briefly review the critical areas delineation, critical areas ratings, and confirm if the critical areas study concurs with Perteet's site visit observations. This assessment memo discusses Perteet's findings and recommendations. The following documents and resource information websites were reviewed by Perteet to aid in the assessment: • Technical Memorandum Re: Wetland and Fish and Wildlife Habitat Assessment and Restoration Plan Denchik Property— 35935 Pacific Highway S, Federal Way, Washington 98003 (King County Tax Parcel Number 2921049020), , Prepared for Dave Denchick, Prepared by Soundview Consultants, dated May 1, 2019 (hereafter referred to as 2019 Critical Areas Study) • Denchick Property— Preliminary Site Reconnaissance Map, dated December 8, 2017, Prepared by Soundview Consultants (hereafter referred to as 2017 Critical Areas econ Map) • Pump Station 33B Barovic Parcel Acquisitions Professional Land Survey dated and signed August 26, 2013, prepared for Lakehaven Utility District, prepared by TetraTech (hereafter referred to as the 2013 Lakehaven Survey) • Technical Memorandum Re: Snyder Property Wetlands, dated October 16, 2009, prepared for City of Federal Way, prepared by Landau Associates (hereafter referred to as 2009 Snyder Study) • Declaration of Posting David Denchick, 35929 Pacific Highway South, Parcel # 2921049020, Case # 19-100931-VO (hereafter referred to as the City violation notice) • Letter from City of Federal Way to David Denchick dated March 7, 2019 Re: File # 19-105697-00-VO; Wetland Buffer Intrusion Denchick Code Violation, 35505 Pacific Highway South, Federal Way (hereafter referred to as March 7, 2019 City letter) • King County Online Parcel Viewer with historic aerial photography through 2017 (htl p: i/www . kin u ntv, oova`` o o=jig—mLG—!SZM— q ps-AL-AP, gipx • City of Federal Way Critical Areas map �ff r �Iwc� � �""/M)' • Google Earth Pro with historic imagery from 1990 to 2018 • Nearmap.corn with historic imagery from 2014 to present (4 11 Denchick CAO Violation — Site Meeting and Report ReAew Memo Page 1 PERTEET ,nvyw,,flt;cr by *iq, 2707 COLBY AVENUE, SUITE 900 EVERETT, WA 98201 425.252.7700 Bill Kidder, Perteef ecologist, completed a site reconnaissance onjune 28, 2019 of the subject parcel and the Lakehaven UD parcel. The landowner, David Denchick, was present throughout the site walk. Perteet entered ind observed the f hree wetlands characterized in the 2019 Critical Areas Study. Perfeet observed the unauthorized activities occurring on the subject parcel and the Lakehaven UD parcel that were gener Ily _jn��blr�r:�ryt4 Pertel th bi to *bserved land clearing, grading, and fill placement in Wetland A and its wetland buffer. Perteet observed fill Pwt-eat observed buildinF construction (remodelinL_i and new construction�ll *n the subject parcel's single family residence within the Wetland A and Wetland B buffer. New construction included a small house addition on the southwest corner and construction of retaining walls. Perteet asked where the property boundaries were for reference to the unauthorized activities, Mr. Denchick described their approximate locations but no precise boundary line markings were present. Mr. Denchick pulled up a 2013 Lakehaven Survey on his phone that illustrated to Perteet that a driveway south of the house was surveyed on the subject parcel and the neighboring south parcel and was a pre-existing feature: The driveway to the north straddled the north property line. Mr. Denchick forwarded the 2013 Lakehaven Survey to Perteet and the City on]my 1, 2019. Perteet observed that the unauthorized activities extended beyond the subject property onto the Lakehaven UD parcel and onto an adjacent parcel to the south (King County tax parcel 2921049104), Parcel 2921049104 is listed - as owned by Sunset Development and Investments (Sunset Development)- The Lakehaven UD parcel contained within the Wetlands A and B buffers vegetation clearing (understory shrubs and a few large conifers), minor regrading of slopes on the parcel's northeast corner, and fill placement at multiple locations. Perteet observed vegetation clearing and fill deposited into Wetland B and its buffer that Mr. Denchick explained come from the .Subject property and driveway improvements. The 2019 Critical Areas Study characterized Wetlands A, B, and C and proposed a restoration plan for the unauthorized actions on the east subparcel of 2921049020, a small portion of the Lakehaven parcel, and the affected areas at the northeast corner of the Sunset Development parcel next to Pacific Highway South. Perteet walked the west subparcel of 2921049020 to confirm whether unauthorize actions occurred on this portion of the subject parcel identified in the City violation notice. Perteet observed additional minor filling and grading on the west subparcel of 2921049020 that extended onto the northwest corner of the Sunset Development parcel. Probable wetlands not characterized in the 2019 Critical Areas Study were observed within approximately 150 feet of this fill and grading area. Perteet was not authorized by the City to enter Denchick-owned parcel 2921049098 based on information known at the time of the site visit. &2_0E Aerial imagery available from Nearmap.com and Google Earth illustrate a distinct change in land development carri F4�#4-,5,44,� areas and critical areas buffers occur on parcels 292104-9020 (subject parcel), 2921049098 (Denchick), 2921049163 (Lakehaven), and 2921049104 (Sunset Development), A time series of aerial photos with annotations Denchick CAO Violation — Site Meeting and Report Review Memo Page PERTEET Better communities, by design 2707 COLBY AVENUE, SUITE 900 EVERETT, WA 98201 425.252.7700 are attached to this memo that illustrate changes in land use site conditions on the violation notice subject parcels and other parcels owned and not owned by Mr. Denchick. TIMELINE November 2017— David Den chich engages in conversations with City of Federal Way regarding land use opportunities and constraints, including critical areas, for parcels 2921049020 (subject parcel) and 2921049098 as part of pre -purchase planning. December 2017— Critical Areas Reconnaissance prepared by Soundview of the subject parcels and adjacent parcels (attached) February 2018—Denchick purchased parcels 2921049020 (subject parcel) and 2921049098 April 2018 — Stockpiles of soil / fill material appear on east side of 2921049098 just outside 2017 Critical Areas Recon Map buffer edge. No other activity observed. May 2018— March 2019—Active land clearing, grading and fill placement on all four parcels. Active building and built features construction on the two Denchick-owned parcels. March 4, 2019 — Permit 19-101002-00-SF issued for "REM — Residing and replace window and doors" on the subject parcel 2921049020. February 27, 2019 — City of Federal Way posted stop work order for 35929 Pacific Highway S. under this violation notice for the subject parcel 2921049020. Much of these additional actions are not visible from Pacific Highway South, They were not known by or presented to the City during a March 1, 2019 violation meeting, during a followup City site visit described in the March 7, 2019 letter, or before Perteet'sjne 29, 2019 site visit and aerial photo review. I 4011-01MM Listedbelow are Perteet's finoings for the critical areas intrusion cndreview of the 2019 Delineation Reporf CritSi9l 2&rgLint"v n 1. Perteet confirmed that unauthorized alterations to critical areas and buffers occurred in 2018 and 2019 that do not conform to Federal Way Revised Code (FWRC) Chapter 19.145 CrificalAreas. Lands were cleared and graded, understory or overstory vegetation was removed, fill was deposited that originated from on -site and off -site, and permanent built features were constructed in wetlands, water courses, and critical areas buffers between April 2018 and March 2019 without City approvals. These unauthorized actions occurred on Denchick-owned tax parcels (292104-9020 and 2921049098) that continue onto parcels 292104-9163 (Lakehaven UD) and 2921049104 without landowner approvals. Pursuant to FWRC 19.145.060(2) Unauthorized alterations, all disturbed areas within critical areas and critical areas buffers shall be restored. 2. A pre -purchase critical areas reconnaissance was completed in December 2017of the four tax parcels listed in item I that illustrates the approximate extent of critical areas and critical areas buffers on these parcels. This reconnaissance was completed prior to the unauthorized activities. A wetland delineation was completed on March 27, 2019, after the City violation notice dated March 7, 2019. The delineation only represents the unauthorized actions on the eastern subparcel of the subject parcel, a small portion of the Lakehaven UD parcel, and the northeast corner of tax parcel 2921049104 (south parcel) that were visible from a public right of way (Pacific Highway South). Additional unauthorized actions occurred in 2017 Critical Areas Recon mapped potential critical areas and critical areas buffer during the April 2018 to March 2019 time period in other areas owned and not owned by Mr. Denchick, These additional unauthorized actions were Denchick CAO Violation — Site Meeting and Report Review Memo Page 3 ^ ^*PERTEET omcoun,AVENUE, SUITE yuu syswsn,wwymzoz *zs.zsazrno observed directly during theJune 29, 2019 site reconnaissance and/or during aerial photo review to compare the current violation extent and timeline with prior-to-2018 existing conditions, Pursuant to FWRC 19.145.060 Unauthorized alterations and .080 Critical area report, all critical areas and critical areas buffers impacted by these unauthorized actions shall be delineated, flagged, surveyed, characterized, and rated. 3. Built features (retaining walls and small house addition) were constructed in wetland and stream buff ers associated with the current violation and a major house renovation and expansion on Denchick-owned parcel 2921049098 during the same time period. Perteet defers to the City regarding already constructed buildings ' additions, and retaining walls within critical areas buffers on parcels 4, All unauthorized critical areas and buffer alterations are subject to the provisions of FWRC 19,145.060 *erence 19A45.140 Mitigafion'A6n RequhwnvP4� Perteet recommends utilizing the King County Critical Areas Mitigation Guidelines as recognized practice standards (and best available science) for completing a critical areas and critical areas buffer restoration plan. The guidelines provide standardized information regarding developing goals/objectives, performance standards, monitoring requirements, plan figures, planting plans, and maintenance/contingency options. A copy of the guidelines is construct ion under FWRC16.45 General Water Quality andEnforcement and 16.50.020 Probibited di5charge5(27) 5ilts, sediments, andgravel. Site restoration required by this violation not ice sha I I be required to implement surface water pollution prevention due to the action's location in and immediately adjacent to surface waters. As soil disturbance, fill removal, and grading is required, Perteet recommends that site restoration work shall comply with FWRC 19.145.190 Physical Barriers and the City's currently approved Construction Stormwater Management Manual Best Management Practices for erosion and sediment control for exposed soil areas. 6. No evidence or presence of costruction temporary erosion sediment controls was observed during the June 29, 2019 site reconnaissance. Soils and fill areas currently remain exposed with little to no vegetation established and no sformwater controls in place. It is advised the landowner install sediment and erosion control BMP as soon as possible in all areas with exposed soils and fill to reduce potential water quality impairments in Wetlands A and B, Hylebos Creek, and Hylebos Creek wetlands, and other wetlands / water courses that may be exposed to water quality impairments in the'southeast quarter of parcel 2921049098. 7. At the City's discretion, the landowner may be required to install critical areas signage and/orfencing pursuant to FWRC 19.145.180. 8. The landowner did not provide evidence of other regulatory agency permits for the unauthorized actions, including a U.S. Army Corps of Engineers Section 404 permit, Washington Department of Ecology Section 401 Water Quality Certification, or Washington Department of Fish and Wildlife Hydraulic Project Approval.

The subject parcel is locatei west of Pacific Highway South and just southwest of S 359" Street in Township 21 North, Range 4 East, Section 29 NW quarter. The subject parcel has been divided into two distinct and geographically separate subparcels. the subject parcel and neighboring tax parcel 292104-9163. This neighboring parcel is owned by the Lakehaven Utility District. The City also requested Perteet to briefly review the critical areas delineation, critical areas ratings, and confirm if the critical areas study concurs with Perteet's site visit observations. This assessment memo discusses Perteet's findings and recommendations. The following documents and resource information websites were reviewed by Perteet to aid in the assessment: • Technical Memorandum Re: Wetland and Fish and Wildlife Habitat Assessment and Restoration Plan Denchik Property— 35935 Pacific Highway S, Federal Way, Washington 98003 (King County Tax Parcel Number 2921049020), , Prepared for Dave Denchick, Prepared by Soundview Consultants, dated May 1, 2019 (hereafter referred to as 2019 Critical Areas Study) • Denchick Property— Preliminary Site Reconnaissance Map, dated December 8, 2017, Prepared by Soundview Consultants (hereafter referred to as 2017 Critical Areas econ Map) • Pump Station 33B Barovic Parcel Acquisitions Professional Land Survey dated and signed August 26, 2013, prepared for Lokehaven Utility District, prepared by TetraTech (hereafter referred to as the 2013 Lakehaven Survey) • Technical Memorandum Re: Snyder Property Wetlands, dated October 16, 2009, prepared for City of Federal Way, prepared by Landau Associates (hereafter referred to as 2009 Snyder Study) • Declaration of Posting David Denchick, 35929 Pacific Highway South, Parcel # 2921049020, Case # 19-100931-VO (hereafter referred to as the City violation notice) • Letter from City of Federal Way to David Denchick dated March 7, 2019 Re: File # 19-105697-00-VO; Wetland Buffer Intrusion Denchick Code Violation, 35505 Pacific F#ghway South, Federal Way (hereafter referred to as March 7, 2019 City letter) • King County Online Parcel Viewer with historic aerial photography through 2017 1 �Cltvbffidirci Iway. cam/ent�, • City of Federal Way Critical Areas map # Google Earth Pro with historic imagery from 1990 to 2018 0 Nearmap.corn with historic imagery from 2014 to present Denchick CAO Violation -Site Meeting and Report Review Memo Page I PERTEET Better communities, by design 2707 COLBY AVENUE, SUITE 900 EVERETT, WA 98201 425.25 2.7700 Bill Kidder, Perteet ecologist, completed a site reconnaissance onjune 28, 2019 of the subject parcel and the Lakehaven UD parcel. The landowner, David Denchick, was present throughout the site walk. Perteet entered and observed the three wetlands characterized in the 2019 Critical Areas Study. Perteet observed the unauthorized activities occurring on the subject parcel and the Lakehaven LID parcel that were generally consistent with the City's violation not ice and follow-up March 7, 2019 City letter. On the subject property, Perte observed land clearing, grading, and fill placement in Wetland A and its wetland buff er. Perteet observed fill ,,-Iccement in the buffer of Wetland C. Perteet observed buildin4e construction hemoclelin• and new construction on the subject parcel's single family residence within the Wetland A and Wetland B buff er. New construction included a small house addition on the southwest corner and construction of retaining walls. I Perteet asked where the property boundaries were for reference to the unauthorized activities, Mr. Denchick described their approximate locations but no precise boundary line markings were present. Mr. Denchick pulled up a 2013 Lakehaven Survey on his phone that illustrated to Perteet that a driveway south of the house was surveyed on the subject parcel and the neighboring south parcel and was a pre-existing feature. The driveway to the north straddled the north property line. Mr. Denchick forwarded the 2013 Lakehaven Survey to Perteet and the City onJuly 1, 2019. Perteet observed that the unauthorized activities extended beyond the subject property onto the Lakehaven UD parcel and onto an adjacent parcel to the south (King County tax parcel 2921049104). Parcel 2921049104 is listed as owned by Sunset Development and Investments (Sunset Development). The Lakehaven UD parcel contained within the Wetlands A and B buffers vegetation clearing (understory shrubs and a few large conifers), minor regrading of slopes on the parcel's northeast corner, and fill placement at multiple locations. Perteet observed vegetation clearing and fill deposited into Wetland B and its buffer that Mr. Denchick explained come from the subject property and driveway improvements. The 2019 Critical Areas Study characterized Wetlands A, B, and C and proposed a restoration plan for the unauthorized actions on the east subparcel of 2921049020, a small portion of the Lakehaven parcel, and the affected areas at the northeast corner of the Sunset Development parcel next to Pacific Highway South. Perteet walked the west subparcel of 2921049020 to confirm whether unauthorize actions occurred on this portion of the -subject parcel identified in the City violation notice. Perteet observed additional minor filling and grading on the west subparcel of 2921049020 that extended onto the northwest corner of the Sunset Development parcel. Probable wetlands not characterized in the 2019 Critical Areas Study were observed within approximately 150 feet of this fill and grading area. Perteet was not authorized by the City to enter Denchick-owned parcel 2921049098 based on information known at the time of the site visit. No evidence or presence of costruction temporary erosion sediment controls was observed during the June 29, 2019 site reconnaissance. Soils and fill areas currently remain exposed with little to no vegetation established and no stormwater controls in place. areas and critical areas buffers occur on parcels 292104-9020 (subject parcel), 2921049098 (Denchick), 2921049163 1wkehaven), and 2921049104 (Sunset Deveior)ment).

TIMELINE November 2017—David Denchich engages in conversations with City of Federal Way regarding land use opportunities and constraints, including critical areas, for parcels 2921049020 (subject parcel) and 2921049098 as part of pre -purchase planning. December 2017— Critical Areas Reconnaissance prepared by Soundview of the subject parcels and adjacent parcels (attached) February 2018 — Denchick purchased parcels 2921049020 (subject parcel) and 2921049098 April 2018 — Stockpiles of soil / fill material appear on east side of 2921049098 just outside 2017 Critical Areas Recon Map buffer edge. No other activity observed. May 2018 — March 2019 — Active land clearing, grading and fill placement on all four parcels. Active building and built features construction on the two Denchick-owned parcels. March 4, 2019 — Permit 19-101002-00-SF issued for "REM — Residing and replace window and doors" on the subject parcel 2921049020. February 27, 2019 — City of Federal Way posted stop work order for 35929 Pacific Highway S. under this violation notice for the subject parcel 2921049020. Much of these additional actions are not visible from Pacific Highway South. They were not known by or presented to the City during a March 1, 2019 violation meeting, during a followup City site visit described in the March 7, 2019 letter, or before Perteet'sine 29, 2019 site visit and aerial photo review.

Perteet confirmed that unauthorized alterations to critical areas and buffers occurred in 2018 and 2019 that do not conform to Federal Way Revised Code (FWRC) Chapter 19.145 CriticalAreas. Lands were cleared and graded, understory or overstory vegetation was removed, fill was deposited that originated from on -site and off -site, and permanent built features were constructed in wetlands, water courses, and critical areas buffers between April 2018 and March 2019 without City approvals. These unauthorized actions occurred on Denchick-owned tax parcels (292104-9020 and 2921049098) that continue onto parcels 292104-9163 (Lakehoven UD) and 2921049104 without landowner approvals. Pursuant to FWRC 19.145.060(2) Unauthorized alterations, all disturbed areas within critical areas and critical areas buffers shall be restored. 2. A pre -purchase critical areas reconnaissance was completed in December 2017of the four tax parcels listed in item 1 that illustrates the approximate extent of critical areas and critical areas buffers on these parcels. This reconnaissance was completed prior to the unauthorized activities. A wetland delineation was completed on March 27, 2019, after the City violation notice dated March 7, 2019. The delineation only represents the unauthorized actions on the eastern subparcel of the subject parcel, a small portion of the Lakehaven UD parcel, and the northeast corner of tax parcel 2921049104 (south parcel) that were visible from a public right of way (Pacific Highway South). Additional unauthorized actions occurred in 2017 Critical Areas Recon mapped potential critical areas and critical areas buffer during the April 2018 to March 2019 time period in other areas owned and not owned by Mr. Denchick. These additional unauthorized actions were Denchick CAO Violation -Site Meeting and Report Review Memo Page 3 PERTEET Better communities, by design 2707 COLBY AVENUE, SUITE 900 EVERETT, WA 98201 425.252.7700 the current violation extent and timeline with prior -to-2018 existing conditions. Pursuant to FWRC 19.145.060 Unauthorized alterations and .080 Critical area report, all critical areas and critical jEreas buffers impacted by these unauthorized actions shall be delineated, flagged, surveyed, characterized, and rated. 3. Built features (retaining walls and small house addition) were constructed in wetland and stream buffers associated with the current violation and a major house renovation and expansion on Denchick-owned parcel 2921049098 during the some time period. Perteet defers to the City regarding already constructed buildings, additions, and retaining walls within critical areas buffers on parcels 2921049020 and 2921049098. 4. All unauthorized critical areas and buffer alterations are subjectto the provisions of FWRC 19.145.060 UnauthorlIzedalterations and enforcement. Preparation of a Restoration Plan with performance standards and monitoring requirements is required that meets 19.145.060(2) and (3) and by reference 19.145.140 Mitigation Plan Requirements. Perteet recommends utilizing the King County Critical Areas Mitigation Guidelines as recognized practice standards (and best available science) for completing a critical areas and critical areas buffer restoration plan. The guidelines provide standardized information regarding developing goals/objectives, performance standards, monitoring requirements, plan figures, planting plans, and maintenance/contingency options. A copy of the guidelines attached. I The unauthorized action did not implement construction stormwater TESC or BP. Potential surface water quality impairments may have occurred during land clearing, vegetation removal, fill placement, and construction under FWRC 16.45 General Water Quality and Enforcement and 16.50.020 Prohibited discharges (27) Silts, sediments, andgravel. Site restoration required by this violation notice shall be required to implement surface water pollution prevention due to the action's location in and immediately adjacent to surface waters. As soil disturbance, fill removal, and grading is required, Perteet recommends that site restoration work shall comply with FWRC 19.145.190 Physical Barriers and the City's currently approved Construction Stormwater Management Manual Best Management Practices for erosion and sediment control for exposed soil areas. 6. No evidence or presence of costruction temporary erosion sediment controls was observed during the June 29, 2019 site reconnaissance. Soils and fill area currently remain exposed with little to no vegetation established and no stormwater controls in place. It is advised the landowner install sediment and erosion control BMP as soon as possible in all areas with exposed soils and fill to reduce potential water quality impairments in Wetlands A and B, Hylebos Creek, and Hylebos Creek wetlands, and other wetlands / water courses that may be exposed to water quality impairments in the southeast quarter of parcel 2921049098. T At the City's discretion, the landowner may be required to install critical areas signage and/orfencing pursuant to FWRC 19.145.180. 8. The landowner did not provide evidence of other regulatory agency permits for the unauthorized actions, including a U.S. Army Corps of Engineers Section 404 permit, Washington Department of Ecology Section 401 Water Quality Certification, or Washington Department of Fish and Wildlife Hydraulic Project Approval. If the landowner decides to pursue future land alteration or development actions that directly or indirectly impact wetlands or streams, the landowner is advised apply for all relevant required permits from all federal, state, and local regulating agencies.

An unclassified stream is located directly south of the property within the wedand. Based on discussion with _4*"0400� ItcwMiRaftid on the sub��, Permission gz-7 H was not given to clear and/or grade within 225 feet of a mapped we and area. Page 2 of 4 March 7,2019 Except as provided in Federal Way Revised Code (F)NRC) 19.145.120, no development or improvements may be located within a wetland ' wetland buffer, stream, or stream buffer per FWRC 19.145.330, FWRC 19.145.430,1 and FWRC 19.145.440. Additionally, it appears portions of the understory and vegetation were removed without a current wetland and waterway delineation. The environmental features are part of key drainage basins and city conservation properties monitored by the city's Stotinwater Division. NEXT STEPS Pursuant to FWRC 19.145.060, "Unauthorized Alteration and Enforcementwhen a critical area or its buffer has been altered in violation of Chapter 19.145 "Environmentally Critical Areas," all ongoing development work shall stop and the critical area shall be restored.

This technical memorandum presents the results of the wetland and stream delineations and is provided for use by the City to assess and document the condition of the subject property. 10MUMMM The study area is located within the Puyallup/White watershed (Water Resource Inventory Area 10), Hylebos Creek basin, in Section 29, ToN�,nship 21N, Range 4 SW, located on the western side of Pacific Highway South, between South 369"' Street and South 361" Street. The study area for the wetland and stream investigation consists of the subject property, plus 200 ft surrounding it (which represents the maximum buffer width for critical areas under the City of Federal Way Revised Code (FWRC). The subject property is 6.92 acres in size and consists of vacant, undeveloped land and contains no roads or established trails. West Hylebos Creek runs north to south through the center of the property. A relatively flat depression is located on the western half of the subject property. West Hylebos Creek is located along the eastern edge of the depression, From West Hylebos Creek the topography slopes up steeply toward the east to a north -south oriented ridge. From the ridge the topography slopes gently down toward the east to Pacific Highway South. The bottom of the topographic depression thal houses West Hylebos Creek is at approximately Elevation 155 to 175 mean sea level (MSL), the north - south oriented ridge is at Elevation approximately 195 MSL, and the eastern edge of the subject property I �IMVF iiiii ill IF 11111 iii 1551 ligill Jill !111, MEMMOMEM I Mill 11:11 liJ!111111 111"!! . - 9 4 - .

The USACE and Ecology recommend a preliminary data gathering and synthesis of available background information, followed by a field investigation. 1111,111111 approach to determine the presence or absence of wetlands that requires evaluating vegetation, soil, and hydrology (Table 1). Following this method, an area is determined to be wetland if all of the following three criteria are met: I 1 0 cni • 11 ata on vegetation, soils, and hydrology was recorded on data sheets (Attachment Q as sampling plots (SPs) located in areas meeting the mandatory wetland criteria, and in nearby upland to determine corresponding wetland/upland boundaries. The wetland boundaries were delineated using numbered flagging. The boundaries of wetlands extending outside of the study were estimated based on views from the study area and aerial photographs and/or other information from the background information review. The ordinary high watermark (OHWM) of streams within the study area were delineation based on the methodology provided by Ecology (Olson and Stockdale 2008), which focuses on examining existing hydrologic data and observation of field indicators including hydrology, soil and sediment, vegetation, and marks of scouring, etc. In some instances, the centerline of the stream way was surveyed and notes on the stream width were recorded. All data points were marked using labeled flagging. The boundaries of streams extending outside of the study were estimated based on views fi-om the study area and aerial photographs and/or other information fi-om the background infori-nation review. Locations of features identified in the field, including wetland or stream flagging, sample plots, key habitat features, and/or key structures were recorded using a Trimble global positioning system (GPSJ liand-held device, and maps were prepared using ArcView GIS software. The average accuracy of the field surveyed points is +/- 1.4 ft with the lowest accuracy being +/- 4.5 ft and the highest accuracy being .1 ft. The field survey accuracy is such that the results are intended for planning purposes only, and should • be used as professionally surveyed boundaries for design, permitting, and/or construction 10/16/09 Y:%238%057.010\R\Snyder—WetiandVRP-RSnyderWetland —tm.doe 0 Fish and Wildlife Service's (USFWS's) Cowardin classification system (Cowardin et al. 1979) and the USACE's hydrogeomorphic (HGM) classification system (Brinson 1993). Wetlands were rated according to the Washington State Wetlands Rating System for Western Washington (ruby 2004; Attachment D). This system categorizes wetlands based on their existing functions, including water quality, hydrology, and habitat, as well as the wetland's rarity, sensitivity to disturbance, or irreplaceability. Wetlands were also rated according to the FWRC. Wetland buffers were determined according to Section 19.175.020 (Wetland categories and standard buffers) of the FWRC. Streams were classified according Section 19.05.130 (M definitions) and stream set -backs (buffer widths) were determined according to Chapter 19.165.010 (Setbacks) of the FWRC.

All three wetlands extend off site and off -site portions of the wetlands were estimated based on the City's critical areas maps. Additionally, a stream (Stream 13) is located approximately 25 ft north of the subject property. Stream B was not delineated because it is located on private property; however, field staff noted where the stream entered the ditch along the west side of Pacific Highway South and recorded observations from the public right- of-way. The stream is significant because it appears to be connected to Wetland C. Wetland A is located within a topographic depression on the western half of the subject property and is associated with West Hylebos Creek. Wetland B is located on the southeast portion of the property. Wetland C is located on the northeast side of the property and appears to be connected with Stream B based on Topographic maps and Critical Areas Maps from the City of Federal Way.

All three mandatory wetland criteria are satisfied for Wetland A (see Attachment Q. Vegetation in Wetland A is dominated by trees, shrubs, and emergent species. Wetland A contains a number of mature trees. Soils in Wetland A meet the hydric soils criteria and range from redox dark surface (indicator F6) to loamy gleyed (indicator F2). Indicators of wetland hydrology range from saturated soil (within the upper 12 inches, at the time of delineation) to a high water table (standing water present in some areas at the time of delineation). Portions of Wetland A are sloped and contain small seeps from within the wetland. These seeps drain to West Hylebos Creek. Wetland A is rated as a Category 2 wetland is the Ecology wetland rating system (see Attachment D) and as a Category I wetland under the FVvRC. Under the FWRC, a wetland is rated as a Category I if it contains species recognized by state or federal agencies as endangered or threatened. Coho salmon, a federal species of concern, and steelhead, a federally threatened species, are located within Hylebos Creek (StreamNet website a, various dates) (VVDFW website 2009) (Appleton, W., 2009, Personal Communication). Hylebos Creek bisects Wetland A in a north -south direction. Wetland A contributes to stream health and habitat by, shading of the creek, contribution of woody debris, and nutrient cycling. The FW_RC requires a 200-ft standard buffer width, for Category 1 wetlands. The wetland, stream, and buffer areas within the subject properties are shown on Figure 2.

However, several other sources report that salmon species are present in West Hylebos within the project area (StreamNet website a, various dates) (Appleton, W., 2009, Personal Communication). Additionally according to the City's critical areas maps West Hylebos Creek is classified as a "major stream" indicating that it contains or supports, resident or migratory fish. Major streams require a 100-ft standard set -back, in accordance with the FWRC. Stream B is a permanently flowing stream that flows east to Pacific Highway South, where it enters a ditch along the west side of the road. At the time of the field investigation, water depth in Stream B ranged from 0.5 to I inch deep. Substrate is composed of silt to medium sand.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi -enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low -energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean -derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes if estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

Use the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the wetland based on its function. 1. Does the unit have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to identify organic soils)? YES = go to question 3 NO = go to question 2 2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or pond? YES = go to question 3 NO = is not a bog for purpose of rating 3. Does the unit have more than 70% cover of mosses at ground level, AND other plants, if present, consist of the "bog" species listed in Table 3 as a significant component of the vegetation (more than 30% of the total shrub and herbaceous cover consists of species in Table 3)? YES = Is a bog for purpose of rating NO = go to question 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog. 4. Is the unit forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine.

If you answer yes you will still need to rate the wetland based on its Junction. Old -growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi -layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm or 111ore). NOTE: The criterion for dbh is based on measurements for upland forests. Two -hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and "OR" so old -growth forests do not necessarily have to have trees of this diameter. Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 — 200 years old OR have an average diameters (dbh) exceeding 21 inches (53 cm); crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old -growth.

Alderwood soils formed rn glacial deposits under conifers. They occupy upland areas at elevations between 100 and 800 feet. The annual precipitation is 35 to 60 inches, mostly rainfall between October Typical Profile: Depth from Surface: 0 to 27 Inches: Dark brown gravelly sandy loam. May be thinner in depth. 27 to 60 Inches: Grayish brown weakly to strongly consolidated glacial till (hardpan). Permeability: Rapid in surface layer and subsoil above hardpan material. Very slow in the hardpan. Rooting Depth: Roots penetrate easily to the hardpan layer. Roots have difficulty penetrating into the hardpan. Depth to Seasonal High W'ater Table: 2 to 3 feet Available Water Holding Capacity: Seasonally low (Summer) to seasonally high (Winter) Erosion and Slippage Hazard: Moderate, ranging to severe on steeper slope phases Alderwood Series Page 2 Use and Management: Primary uses are for timber, pasture, be production, row crops, and urban development. Pasture forage yields are 2.0 tons/acre/year. Low fertility and summer droughtiness are limiting factors. Douglas -fir, Western Red Cedar, Western Hemlock, Red Alder, and Bigleaf Maple are important tree species on all slope classes. Black Cottonwood can also be an important species on the AgB slope class. These soils have moderate to severe limitations on equipment use for site preparation and timber harvest. These soils have moderate to severe limitations on recreational and engineering uses du.l& to their seasonal high water table and very slow permeability in the hardpan layer for all slope classes and erosion/slippage potential in steeper classes. Alderwoods which are farmed should be kept in permanent type crops 75% of the time, with not more than one consecutive year of row crops or small grains between permanent seedings. Crops respond well to applications of manure, fertilizer, and supplemental irrigation. MI I ILI 01 1511 Dky U OM41 'd Everett gravelly sandy to EvB: 0 to 5% slopes EvC: 5 to 15% slopes EvD: 15 to 30% slopes very gravelly sand. These soils formed in very gravelly glacial outwash deposits under conifers. They are found on terraces and terrace fronts and are gently undulating to moderately steep. The EvD phase of this soil tends to be located along drainageways or on short slopes between terrace benches and are stonier and more gravelly. The annual [1,recipitation is 35 to 60 inches. The frost -free season is between 150 and 200 days. Typical Profile: Depth from Surface: 0 to 17 Inches: Dark brown gravelly sandy loam 17 to 32 Inches: Brown very gravelly sandy loam 32 to 60 Inches: Black and dark grayish brown very gravelly coarse sand Rooting Depth: 60 inches+ Depth to Seasonal High Water Table: No seasonal high water table within a depth of 5 fel Available Water Holding Capacity: Low am= Erosion and Slippage Hazard: Slight to severe depending upon slope sun= M. L Primary uses of these soils are for pasture, timber, and urban development on gentler slopes and timber on the steeper slopes. Pasture forage yields for the B and C phases are 2.0 tons/acre/year with goof management. Forage production may become linuited in Summer by the low water holding capacity of the soil. Douglas -fir, Western Hemlock, Red Alder, and Bigleaf Maple are important tree species on all soil slope classes. The EvD phase has moderate limitations on equipment use for site preparation and timber harvest. Caution should be used to avoid unnecessarily disturbing the vegetation on this phase to avoid problems with erosion, runoff, and slippage. These soils have moderate to severe limitations on certain recreational and engineering uses due to the large amount of gravel and high permeabilities in all slope phases and the steep slope in the EvD slope phase. Tukwila Muck Mapping Symbols: Tu The Tukwila series consists of very poorly drained organic soils that formed in decomposing sedges, rushes, grasses, and shrubs. These soils are in wet basins of upland tepressions and on stream bottoms. Slopes are 0 to 1%. The annual precipitation is 35 to 80 inches and the mean annual temperature is 50 degrees F. The frost -free season is about 150 to 200 days. Elevation ranges from 25 to 750 feet. Typical Profile: Depth from Surface: 0 to 60 Inches: Black to very dark brown muck Permeability: Moderate Rooting Depth: 60 inches + if drained Depth to Seasonal High Water Table: 0 to I foot Available Water Holding Capacity: High Use and Management: If drained, Tukwila soils are used for row crops and pastures. They have severe limitations for agricultural and forestry use, forestry, engineering, and recreational purposes because of the organic content, high water table, and poor drainage.

City Response: You can construct a single family dwelling on a minimum of five acres in the SE zone. If you have less than ten acres, you may be able to do a boundary line adjustment to create two lots if the lots meet the following Federal Way Revised Code (FWRC) code sections: 19.105.010 Buildable lot,.

Lots that are not considered buildable lots are those that were not created for the vacated rights-of-wa' jk tracts, lot fragments resulting from surveying errors, public or private easements, and "Primary vehicular access" means the street, vehicular access easement, or private tract from which the majority of vehicles enter the subject property. "Lot area" means the minimum lot area per dwelling unit based on the underlying zone. For single-family lots, the area of a vehicular access easement, private tract, flagpole, or access panhandle shall not be credited in calculation of minimum lot area. 4. Irrespective of questions #1-3... Lot 2921049098 is 9.38 acres, and currently contains a rambler house on a septic system with a fresh water well. Which appears to be livable and currently has a family living there. Is it possible to retain this as a guest house and construct a new single family residence with its own septic system on the property (assuming there is appropriate land mass to install an additional drain field?). The ADU rules •a • clearly cover this scenario. The existing home is 1,640 sq. ft. An ADU, excluding any garage, workshop and similar nonliving areas, shall contain between 300 — 800 sq. ft., but shall not exceed 40% of the sq. ft. o the • dwelling unit, excluding • workshop and similar nonliving areas. The unit sh have no more than two bedrooms. The existing home would not qualify as an ADU due to its I size. I 5. Are there any potential limitations that the city will impose on the new owner precluding from constructing additional buildings on the property for residential use (shop, garage, etc)? M= The maximum lot coverage in the SE zone is 10 percent and setbacks for a detached dwelling unit Umd%,sUeom or their respective buffers unless approved by the City through the appropriate process. 6. Currently on the lakehaven LOT is a "monitor well" installed. However, I cannot find record of this no one seems to know anything about it. How does this monitor well affect potential use MMMMMMM 7. North of the property is part of the Hylebos wetland, however the cleared area making up th majority of lot 2921049098 was used as an animal shelter, grazing fields, etc. Is there anytthil already known that would not permit me to construct a new dwelling and retaining the exist rambler as a separate dwelling or be classed as an ADIJ? W= Refer to Response #4. You would need to have the wetland and stream delineated and buffers identified in order to determine where new building can occur (See Bulletin #004). 8. On Pacific Highway at the entrance of the property is three mailboxes numbers: 35929, 35931 and 35935. It doesn't appear to be correctly illustrated in the GIS map as far as the parcels addresses. I would like to gain clarification as to how these "house" numbers relate to the 4 sections of land depicted in GIS. I believe that Parcel 2921049020 is 35929 pacific hwy s, and 2921049098 is 35935 pacific hwy s, and then 35931 belongs to lakehaven plot? It appears that Parcel #292104 9098 is 35929 and Parcel #292104 9020 was 35935 prior to Lakehaven acquiring the middle parcel based on the Assessor's Map. However, it is not clear. Refer to the table. The address 35931 does not pull up a parcel on the Assessor's Map. 9Lastly, regarding to zoning of SE, it appears that that at one point in time parcels 292104903 8, 2921049163, 2921049020 were a single 5 acre parcel, which coincides with the zoning for this area. Given that the parcels are now under 5 acres in size, and specifically with the acquisition of approximately 0.76 acres by lakehaven from lot 2921049020 makes this parcel even smaller. Does this place any additional restrictions on the parcel, since it is still zoned as SE, does the city plan to rezone these parcels? ��* 0 1 �- (0. Does the city have any documents or wetland studies that would more or less indicate the boundaries of the Hylebos wetland. The seller has state that there is no wetland, or sensitive biological area on the property and that the wetland terminates to the north of the parcel 2921049098. The city's Critical Areas Map shows a stream and considerable wetlands on this property. A buffer up to 225 ft. may be required. The city will require a stream and wetland delineation re -fort at the owner's ex�tense. f See Bulletin #004 for details�,.
