00-105878 (2) 4r CITY OF G II L E • EIZIE Fry CITY HALL 33530 1st Way South (253) 661-4000 PO Box 9718 Federal Way, WA 98063-9718 December 28, 2000 Mr. Jon Jainga, Parks Development Manager City of Federal Way, PARCS 33530 1st Way South PO Box 9718 Federal Way, WA 98063-9718 Re: File Number: 00-105878-00-UP; NOTICE OF INCOMPLETE APPLICATION Skate Park at Steel Lake;2410 South 312`h Street,Federal Way Dear Mr.Jainga: The Department of Community Development Services received information you submitted on December 4, 2000, for the proposal to construct a skate park at the above referenced site. The project is being reviewed under the Process I provisions. Pursuant to the requirements of the Federal Way City Code (FWCC),the City has 28 days to determine whether an application is complete. INCOMPLETE APPLICATION During the course of the City's review,the following items were found to be incomplete.In order for your application to be considered complete and ready for processing,the items below must be provided: 1. Survey—As stated in the May 11, 1999,preapplication letter,a survey,which documents the location of existing property line and existing improvements must be submitted to determine the proposed location of the Skate Park improvements. 2. Landscape Plan—As stated in the May 11, 1999, preapplication letter,a landscape plan must be submitted. Also, refer to page 2 of this letter. 3. Technical Drainage Information Report—As stated in the May 6, 1999, memorandum from Public Works Engineer Ann Dower, a level one downstream drainage analysis and an narrative addressing the 7 code and 12 special requirements must be submitted. The information from Debbie Maroon, PE,does not satisfy this requirement. 4. Valuation Information—As stated in the May 13, 1999,memorandum from Public Works Traffic Analyst Sarady Long, a value estimate for the new park must be submitted with an appraisal or assessed value of the existing structures at Steel Lake Park. This information has not been provided. »4 ; Mr. Jbn Jainga Page 2 December 28, 2000 PRELIMINARY PROCESS I COMMENTS FROM DEVELOPMENT REVIEW COMMITTEE In addition to submittal requirements previously discussed,preliminary Process I review comments are provided below. These issues were identified in reviewing the application for completeness. Responses to these items listed below are helpful in expediting the project when the City begins formal review. PLANNING DIVISION,Deb Barker,253-661-4103 1. Process I Criteria—As stated in the preapplication letter,the proposal can be reviewed under Process I,Directors Decision, as long as there is no change of use, no reduction in the amount of required landscaping,buffering or open space,no change in parking or pedestrian connections,nor impacts to sensitive areas or significant trees. Please provide a written response that demonstrates how the project does not impact these items. In the event that the project does not meet these criteria, it will be processed as a Process II application. 2. Size of Project—Provide the specific square footage of the project, including the amount of proposed grading and filling required for the project. 3. Pedestrian Pathway—As stated in the preapplication letter,a four-foot wide pedestrian access from the parking area to the skate park must be provided per FWCC Section 22-1634(d).

Maintenance and Operations Manual City of Federal Way—Skate Park Section 1 Technical Information Report Project Overview 1. PROJECT OVERVIEW This TIR has been prepared as support for the plans for a skate park to be constructed at Steel Lake Park by the City of Federal Way Parks Department. The park will be constructed at the southwest corner of the intersection of South 312th Street and 28`h Ave South. The site was previously used as a storage yard for construction. Most of the site has been cleared and only a few trees remain scattered around the site. Grass covers most of the site but in some areas bare ground and gravel were observed. Standing water was observed on the site during a site visit on February 23,2001. Little runoff currently enters the site from surrounding areas. The land to the south and west is lower than the site itself and runoff from the north is intercepted by an existing ditch along 312`h. An existing swale along the east side of the proposed skate park intercepts any flow from the east. Under current conditions runoff from the site flows north to the ditch along 312th or to the south through the swale along the east side of the proposed skate park. Under developed conditions runoff from the site will be directed to the ditch along 312`h. The ditch discharges to an existing wetland along the west side of Steel Lake Park. (See Section 3 of this TIR for a complete downstream description) The site is located in the Hylebos Creek Drainage Basin. Steel Lake Park is approximately 54 acres in size, including the portions of the park on the north side of the lake. The construction of the skate park will add slightly less than 10,000 square feet of new impervious area to the park. No new parking or access facilities will be required for the skate park. Parking is not allowed on 312th and persons driving to the skate park will park in existing parking lots located to the west of the skate park.

LEVEL 1 OFFSITE ANALYSIS Below is a description of the downstream system: Beginning at the northwest corner of the site the storm water would discharge to an existing ditch along the south side of South 312`h Street. The ditch is approximately 1-1/2 feet deep, 2 feet wide at the bottom with 3 to 1 side slopes. The storm water would flow westerly for approximately 100 feet where it will enter a 12"concrete culvert under an existing driveway. The culvert is approximately 40 feet long and has a slope of approximately 2%. From the culvert the flow enters another ditch which is approximately 18"deep, and 2 feet wide at the bottom. The flow continues in this ditch for approximately 260 feet where it enters a second 12"culvert under an existing driveway. Approximately 20 feet upstream from this culvert another 12"culvert discharges to the ditch. Scour is evident at the discharge point from the upstream culvert. The culvert under the driveway is approximately 60 feet long and is at a 2% slope. There is scouring at the end of the culvert. After exiting the culvert the flow enters a ditch which is 18-24"deep, 2 feet wide at the bottom with 3 to 1 side slopes. This ditch continues for approximately 60 feet where the flow enters a 12"concrete culvert under an existing driveway. The culvert is approximately 40 feet long and has a slope of approximately 2%. Scouring is evident at the end of the culvert. After exiting the culvert the flow enters a ditch that is 18-24"deep, 3-foot wide at the bottom, with 4 to 1 side slopes. This ditch has areas of minor erosion and has silt in the bottom in several locations. The flow continues in this ditch for approximately 100' to a wooded area that drains to the south. The flow meanders through the woods for approximately 1000 feet before it reaches an apartment complex and a piped system. At the time of the downstream the ditch had recently been cleaned and little or no vegetation remained. Most of the erosion in the ditches appears to be a result of no vegetation in the ditches and vegetation needs to be re-established in the ditches. The scour at the culvert outlets was relatively minor and could easily be handled by placing riprap around the culvert outlets. System maps have been obtained from the City of Federal Way and are included in this Section. The culverts and ditches along 312th and the ditch/wetlands on the Steel Lake Park site have been added. These system maps show the drainage from the site the south side of 320th.

FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN Discharge at Natural Location Based on the USGS Quad map(Poverty Bay,Washington)prior to any grading taking place on the site the site drained by sheet flow to the low area located on the west side of Steel Lake Park. Under developed conditions the flow will still enter that low area and therefore, is being discharged at it's natural location. Flow Control The project is located in an area where Level 1 Flow Control would normally be required,unless a downstream problem has been identified. Level 1 Flow Control requires that the peaks from the developed 2-yr and 10-yr storm events match the peaks from the existing 2-yr and 10-yr. There are eight possible exemptions from the requirement to provide a formal flow control facility per Core Requirement #3. Per the SWDM the intent of these exemptions is to provide for situations where a facility may not be practical or needed. If the skate board park is looked as a small part of the Steel Lake Park,which it is, the project is exempt from flow control under Exemption 2,which is stated below. 2. Impervious Surface Exemption Using Flow Control BMPs Any threshold discharge area within a proposed project is exempt if less than 10,000 square feet of new impervious surface will be added,AND all of the following criteria are met: a) The area cleared to accommodate the proposed project must be less than 35% or less than 2 acres of the threshold discharge area(whichever is greater), AND b) If the project is a single family residential project, flow control BMPs must be applied within the threshold discharge area as specified in Small Site Drainage Requirements (detached Appendix C), AND c) For projects other than single family residential projects,the new impervious surfaces within the threshold discharge area must be comprised of either non-pollution-generating roofs that comply with the roof downspout controls in Section 5.1,OR roads,trails,or driveways that comply with the rural roadway dispersion requirements in Sections 5.2.1, AND d) The manner in which runoff is discharged from the project site must not create a significant adverse impact per Core Requirement#1. The project clearly meets criteria a). The project clears less than 12,000 square feet. The project is not a single-family residence and therefore,criteria b) does not apply. The intent of criteria c)and d)is to assure that runoff from the site is not concentrated and discharged to a downstream property in such a way to cause an adverse impact. Runoff from the park will be dispersed in a dispersion trench to be constructed along an existing parking lot preventing concentration of the flow within the existing ditch along 312t thus meeting the intent of criteria c)and d).

The project meets all three of the criteria. The project is not adding any new PGIS surfaces as the park will not be subject to vehicular use nor will erodable or leachable materials,wastes, or chemicals be stored on the skate park. The project does not create 5,000 feet of contiguous PGIS surfaces through any combination of new and/or replaced impervious surface as part of a redevelopment project and less than 1 acre of contiguous PGPS will be added.

City of Federal Way—Skate Park Section 5 Technical Information Report Conveyance System Analysis and Design 5. CONVEYANCE SYSTEM ANALYSIS AND DESIGN A 12-inch pipe will convey storm water runoff from the skate park to the existing ditch along 312`h. The pipe will be installed at a minimum slope of 0.5%. The peak runoff flows from the skate park have been determined for the 10-year, 25-year, and 100-year storm events using the rational method. The rational method was chosen since the entire drainage basin is less than 10,000 square feet. In addition, the capacity of the existing ditch and culverts were determined in order to assess the impact that discharging the stormwater runoff from the skate park would have on the existing ditches and culverts.

The Parks,Recreation and Cultural Services Department is submitting the additional items as requested in your December 28, 2000 letter regarding file number: 00-105878-OOUP. The items included in this packet are: 1. Background of Skate Parks. 2. A Site—Survey Map of Steel Lake Park. 3. Landscape Plan. 4. EarthTech Engineering of Bellevue, Technical Information Report. 5. CML &Associates of Bellevue,Valuation Information, and Summary of Improvement Values of Steel Lake Park. I:\skatepkresubmitletter.doc 1 4 1. Background of Skate Parks. For the last three to four years, parks and recreation departments around the United States have been creatively developing new play structures and sports courts to meet a fast growing community recreational need for today's youth. In 1983, the State of Washington began picking up on California's latest recreation crave. Skate boarding. The cities of Yelm, Moses Lake, Seattle and Bellevue were some of the first cities in Washington to identify this latest youth recreational need and started building skate board structures within their park systems. The Skate Board Parks are concrete or asphalt play structures designed to give the community youth a safe recreation area to skate within an existing park system. Some cities have even been as creative as to using existing parking lots to create an inexpensive play event in order to make the project feasible for their city and community. And more importantly to make it happen for the youth of the community. Most every city has an ordinance and/or city codes restricting youth to skate in public areas. A skateboard park or in another descriptive term, a sports court, is no different than a `Bigtoy' play structure. The `Bigtoy' play structures satisfy and meet the recreational need for youth ranging from ages 3 to 10. The play structures meet a community need and provide a safe area for youth to play in a designated area of an existing park. The skate parks do the exact same thing. We have identified a community recreational need for the older youth ranging from age 8 and up. Many adults use these structures as well. The skate parks are simply new play structures or sports courts installed in existing park systems to give the youth a safe and non-restricted area to skate. The skate park is a new play structure designed to meet the recreational needs of today's youth. The skate park at Steel Lake Park is not the development of a new park; we are simply adding a new play event to an existing park that can support its recreational need. Steel Lake Park is the best location for the skate park. The Parks and Recreation Commission and the Council Committee have hosted five public meetings within the last three years and are now funding this project. The youth have spent hours with the consultants designing the best elements for the structures, this has given many of them hope and ownership in the project. 2. A Site Survey. The survey map shows the location of all the existing property lines and existing improvement at Steel Lake Park and the proposed location for the skate park site. The skate park structure is located in the northeast corner of the Steel Lake Park `Annex' side (this being the south half of Steel Lake Park). The Steel Lake Park `Annex' provides the existing improvements: (1) Steel Lake Park Recreation Building, (2)Parks Maintenance Building, (3)Public Restrooms, (4) Tot Lot(Play Structure for youth), (5)two baseball fields and(6) one soccer field. The Annex also provides an existing parking lot for 64 vehicles and existing asphalt pathways for pedestrian circulation. The Steel Lake Park has all the existing park elements to support the skate park's structure and its users. Most of the users will be dropped off and picked up by Mom or Dad. Some will even walk or ride their bikes to and from the site. Bike racks existing at Steel Lake Park for park users that wish to ride their bikes to the park. The existing parking lot is more than adequate for the site and will handle the parents' vehicles dropping off or picking up during the parks operation. The Steel Lake Park hours of operation have the same operating hours parallel to all other city parks. The city parks are open to the public from dawn to dusk. The users also are to follow and obey all park rules as stated in Ordinance Number 91-82 of the Federal I:\skatepkresubmitletter.doc 2 1 Way Municipal Codes. The skate park will be signed with specific rules outlined by the Associated Cities of Washington's Risk Management Division regarding the public use, safety and personal responsibilities and liabilities while using the skate park. 3. L-1 of the submitted Landscape Plan. The landscape plan indicates the lawn restoration work and D-1 of the submitted plans also shows the proposed brush removal areas, which the Parks,Recreation and Cultural Services Department will be doing with community volunteers. The Parks, Recreation and Cultural Services Department will not be planting a Type III Landscaping Buffer along the north and east property lines of Steel Lake `Annex' Park. The newly accepted FWCC, Article XIX—Community Design Guidelines, supports the reasons for not planting a Type III Landscaping Buffer. A Type III Landscape Buffer or any buffer will impede the site lines looking into and out of Steel Lake Park. The skate park structure is close to the 312th Street and 28t Ave S intersection and across from the city's Steel Lake Maintenance Building. By screening the park's properties lines, you will be blocking the site lines into the park and most important the site line looking at the park from the city's maintenance shop. The Parks, Recreation and Cultural Services Department oppose any landscape buffer along any of our parks. Screening the property lines at Steel Lake Park would increase and encourage vandalism and criminal acts in our parks. The city's goal is to provide safe recreational and leisure places within the City of Federal Way. It is important to keep the site lines open, looking into and looking out of the park. This is why we do not favor any landscaping buffer around any of the city park properties. From experience,we have found that screening the parks create opportunities for vandalism and criminal acts to occur. Public safety for our users is the number one priority. Our city parks are large green landscaped open public area, with many services for the community. The intent of the parks is not to screen the view in or out. It is the intent to look in and through. Many of the park users enjoy looking into the park as they pass by during their daily activities. The intent of the skate park is to have good site lines looking in, out and through. In all the surrounding cities of the northwest,no skate park has been screened to hide it from public viewing. 4. Technical Report. Attached is the Technical Report completed by EarthTech engineering addressing the core requirements. The Technical Information Report has been prepared as support for the plans for the skate park to be constructed at Steel Lake Park. The site was previously used as a construction storage yard for the Public Works Department during their renovation of South 312th Street. Most of the site has been cleared and only a few trees remain scattered around the site. Grass covers most of the site but in some areas bare ground and gravel exist. Little runoff currently enters the site from the surrounding areas. The land to the south and west is lower than the site itself and runoff from the north is intercepted by an existing ditch along South 312th Street. An existing swale along the east side of the proposed skate park intercepts any flow from the east. Under current conditions runoff from the site flows north to the ditch along South 312th Street and to the south through the swale along the east side of the proposed skate park. Under developed conditions runoff from the site will be directed to the ditch along South 312th Street. The ditch discharges to an existing wetland along the west side of Steel Lake Park. The site is located in the Hylebos Creek Drainage Basin. I:\skatepkresubmitletter.doc 3 Steel Lake Park is approximately 54 acres in size. The construction of the skate park will add slightly less than 10,000 square feet of new impervious areas to the park. No new parking or vehicular access facilities will be required for the skate park. Parking is not allowed along South 312th Street and persons driving to the skate park will park in existing parking stalls located to the west of the skate park structure. 5. Valuation Information. Attached again is the completed Steel Lake Appraisal Report. The report includes the estimated land value of$7,530,000 and the improvement value of $1,720,000 of existing park structures. This same report was used in order for the Public Works Department to remodel the maintenance building without improving the street frontage for their project. CML&Associates of Bellevue have been appraising city properties for the last six years. They have completed their assignments of appraising the property and determining a professional value of existing improvement at Steel Lake Park. The summary of existing improvement values is listed in Chapter III,page 14 of the report. The engineer's construction estimate is $196,000. The project does not exceed Steel Lake Park's improvement value of the city's 25%margins determined by Public Works to trigger any street front improvements. Preliminary Process I Review The Parks, Recreation and Cultural Services Department is requesting that this project be reviewed under the Process I guidelines. Process I Criteria: The Skate Park project at Steel Lake Park meets and exceeds the following Process I Criteria: 1. The Parks, Recreation and Cultural Services Department is requesting the Community Development Director to review the Skate Park project at Steel Lake Park, File Number 00- 105878-OOUP, for the compliance under the provisions of Chapter 22-351 of the Federal Way Land Use Codes. 2. The Skate Park project at Steel Lake Park will not jeopardize, change and destroy the health, safety and welfare of the citizens of Federal Way or any other park user at Steel Lake Park. 3. The Parks, Recreation and Cultural Services Department is requesting the Community Development Department to provide an expedient, fair and reasonable land use review process for administrative decisions and interpretations of Chapter 22 of the Federal Way City Code. An expedient, fair and reasonable review of this process is necessary to be timely so the Parks, Recreation and Cultural Services Department can proceed with the public bidding process for the construction management of this project. A delay would bring a hardship to this community project, the participants and the Parks, Recreation and Cultural I:\skatepkresubmitletter.doc 4 Services Department. 4. The Parks,Recreation and Cultural Services Department is requesting the Community Development Director to make an interpretation based on a logical or likely meaning of the provisions viewed in relation to the comprehensive plan and other related plans, i.e. the Parks, Recreation and Open Space Comprehensive Plan, adopted September 5, 2000. The Skate Park project meets all the Park's public planning process outlined in the Parks, Recreation and Open Space Comprehensive Plan. 5. The City of Federal Way has determined by adoption and definition that Steel Lake Park is a public park. Steel Lake Park is a public park within the city limits and used for the sole propose of recreation. The Steel Lake Park is located in the Steel Lake Neighborhood and adjacent to the downtown"City Center Core" along the north side. 6. Through public surveys and meetings, the City of Federal Way has identified a recreational need for a skate park structure to be built within the City. The Skate Park project at Steel Lake Park meets and fulfills the recreational need for the youth, age ranging from 8 years and up. 7. This project is in the best interest of the Federal Way Community. The Parks and Recreation Commission and the Council Committee have been involved throughout the planning process and have hosted five public meetings within the last three years. The City Council has approved the development funds for the skate park project as part of the 2000 approved budget. 8. The structure does not exceed 15' above the average building elevations. 9. The park rule signs meet the city's sign code requirements. 10. The project meets the requirements outlined in the Community Design Guidelines. 11. The Skate Park structure is 9,600 sq. ft. in size. Approximately 3,000 sq. ft. will be cut or excavated at the site. The estimated cut is 300 cu. yds. of existing sandy loam soils. This 300 cu. yds. of cut will be used on site to elevate the upper half of the skate structure. In skaters terms, to create the ramps,hips,pikes, seats and funbox. Additional gravel and concrete will be imported to the site in order to complete the balance of the structure. The highest point of the structure will not exceed 5' from the existing grade. 12. Pedestrian Path: As part of the Skate Park project, a 5' asphalt path will connect to the existing pedestrian asphalt path which will connect the Skate Park to the existing parking lot. (see the site map for an illustration) 13. Light: No additional park lighting be will installed at Steel Lake Park. I:\skatepkresubmitletter.doc 5 14. Landscaping: To keep the park access visible, no landscape buffer is being planted along the Steel Lake Park property lines. Again,this is to provide safe site line looking both directions into and out of the park. This is within the recommendations of the Community Design Guidelines. 15. Public Restroom: As shown on the Site Map, Public Restrooms are provided in the area of the park and have existed since the park was built. 16. Public Parking: As shown on the Site Map, Public Parking is provided for 64 vehicles. The existing parking is adequate and will handle the parking for the Skate Park structure. No new public parking is being added to Steel Lake Park. Thank you for your help during this process. Please call me if you have any question regarding this project.

Highest and Best Use Analysis The highest and best use of a property is that use, among all alternative uses,that provides the greatest return to the land. In this appraisal,highest and best use is defined as: The reasonably probable and legal use of vacant land or improved property,which is physically possible,appropriately supported,financially feasible,and that results in the highest value.(Appraisal Institute,The Appraisal of Real Estate, 10th ed., 1992,p.45) In the appraisal analysis,the highest and best use of property is evaluated in two ways: as if the site is vacant and as currently improved. To be designated"highest and best"; a ( potential use must meet four tests. The use must be: • Physically possible, • Legally permissible, • • Financially feasible, and • among uses that meet the preceding three tests,the"highest and best use"must yield the highest return. Highest and Best Use The subject property is currently being used as a park facility and this use will be continued in the future. The site is zoned SE, suburban estate residential, with permitted uses as a park, daycare center, single-family, public facilities, etc. However, the surrounding land uses dictate either multi-family or single-family residential development, but the zoning code indicates single-family residential is allowed; whereas, multi-family uses are not. The zoning information was supplied by the City of Federal Way Permit Center. Therefore, the site will be valued at the highest and best use, which is single-family residential as though vacant. Reference: 1268-799 Steel Lake Park CML & Associates, Inc. Chapter II Page 4 L'. F III . Valuation L The Sales Comparison Approach is normally the preferred method of valuing land as though vacant and ready for development.Furthermore, the Cost Approach will eused to estimate the market value of the subject property. The Cost Approach to value is whereby the accrued depreciation is deducted from the cost new of the improvements and this figure is added to the land value to indicate the value of the whole property. The Cost Approach is most applicable when valuing property that is relatively new and suffers minimal depreciation along with special-purpose properties such as the subject, which are not normally bought and sold in the open market. The Income and Sales LComparison Approach are not applicable in this appraisal due to the reasons mentioned ;;. above. The Cost Approach is the best indicator to determine a ratio of improvement value to land value. r, The Cost Approach Land Valuation In the appraisal of urban,residential unimproved land,the most common unit of comparison is price paid per lot. Through comparison to sales of similar properties, value is estimated based upon adjustments to the comparable units of comparison, which take into account dissimilarities between the comparables and the subject. The price paid per lot will be used in this analysis to compare the sales to the subject property. Assumption for the Valuation of Non-Park Land The subject property will be analyzed on the basis of its highest and best use not it's current use as of the date of the appraisal and the highest and best use is residential development primarily single-family. Therefore,the number of potential lots that can be placed on the subject property is 251 lots(based on the assumption that the average lot size is 7,200 square feet) with the assumption that roads and open space will account for 25 percent of the site area. The remainder will be for potential lot development,which is 41.56 acres out of 55.42 acres. Comparable Land Sales [.. The comparable land sales used in this analysis were obtained by search of public records at the King County Courthouse, from MetroScan, COMPS, and Experian. Where possible, each sale was confirmed through conversation with parties involved in the transactions. The sales are summarized in the following table, with a detailed description ffof each sale retained in the appraiser's files. Reference: 1268-799 Steel Lake Park CML & Associates, Inc.

The property sold in July 1997 for $2,171,200, or$103,390 per acre, or$33,925 per lot. This transaction was part of a rolling option for the developer. The property sold with preliminary plat approval and plans. Comparative Analysis P Y Unit Analysis: For single family subdivision analysis,the best unit of comparison is price paid per developable lot. I have therefore used this as the unit of comparison. - Cash Equivalency: All of the sales were cash transactions and do not require adjustments for cash equivalency, except for Land Sale 4, which appeared to have market rate financing. Time Adjustment: The sales occurred between July 1997 and May 1999. The prices do not reflect current market conditions. Recently,there has been increasing upward pressure on land values and upward adjustments are made for the passage of time. rPa Size Adjustment: The sales range in size from 2.96 to 26.00 acres, net. The subject property, at 55.42 acres is above the higher end of this range established by the comparable sales. Typically, smaller parcels sell for a higher per unit price than larger ( parcels. The price per acre values generally support this with the largest sale selling at the 1 lowest price per acre and the smaller sales selling for higher per acre values.Sale 2 has a higher price per acre due to overall size of the site. On a price per lot basis, overall size has less impact on price per lot. Since I will be analyzing the sales on a price per lot basis, a size adjustment will not be applied. Lot Density: This adjustment refers to the number of lots achieved on the site. Typically, the higher the density,the lower the lot price, however, in the case of these comparable sales, there does not appear to be any correlation between lot density and purchase price. The subject property's lot density is 6.04 lots per acre, which is similar to Sale 1, 2, and 3. The sales do not support an adjustment for lot density. Platted Status: Land that sells with preliminary plat approval is worth more than land which sells without approval. Most of the comparable sales sold with preliminary plat approval, except for Sale 4 and 5. However, in each case, the purchasers signed earnest money agreements prior to receiving plat approval and the sales were, in most cases, contingent on receiving plat approval. The subject property has received preliminary plat approval as of the date of the appraisal and is considered to be similar to the sales in Reference: 1268-799 Steel Lake Park CML & Associates,Inc. Chapter III Page 3 f terms of platted status(no plat approval at the time of sale). No adjustment is made for this factor. Location: The location adjustment accounts for neighborhood, access, traffic, government jurisdictions, school districts, and the availability of utilities.All of the sales are located with incorporated areas.. No adjustments are made to these sales.

Based on conversations that I've had with several developers, $28,000 to $35,000 per lot is still the targeted purchase price for raw land that is considered a reasonable commuting distance from major employment centers. Considering the sales analyzed and considering the subject's size and number of proposed lots, it is my opinion that the market value of the subject property is $30,000 per lot. Land Value Conclusion The total estimated market value of the subject property's land, as is (if the land was not a park site), based on 251 proposed single-family lots as follows: { Land Value Conclusion 251 lots @ $30,000 per lot equals $7,530,000 Reference: 1268-799 Steel Lake Park CML & Associates, Inc.

The submittal is incomplete for Public Works Review because it does not include a preliminary Technical Information Report and the "downstream analysis" that was provided does not include sufficient information. Please include the following items in any future submittal: 1. A narrative addressing the 8 core and 5 special requirements outlined in the 1998 King County Surface Water Design Manual (KCSWDM) and the Federal Way Addendum to the KCSWDM. 2. The downstream analysis must include maps showing the upstream tributary area and the downstream system. 3. The downstream analysis must identify and suggest mitigation for any existing or potential problems. That would include any effects the project may have on the scouring identified near several of the culverts. It would also include any downstream and/or basin-wide conveyance and detention problems to which this project drains. / The plans must show how storm water will be detained. Include profiles and show the location and type of control structure. Also show the entire conveyance system. 5. The plans must show the following items: a. Area of the site b. Impervious surface area c. Existing property lines d. Proposed property lines, including right-of-way dedication e. Existing drainage ditches f. Location, width and names of abutting streets g. Show and/or label existing edge of pavement h. Existing utilities (water, sewer, storm, fire hydrants, phone, power, gas, cable) i. Required street improvements 6. Please provide the full appraiser's report, not just one page. 7. Please verify that the appraiser is MAI certified. 8. In the appraisal, under "Summary of Improvement Values", there is a statement reading, "the table below summarizes the depreciated cost new values of the improvements." Please clarify this statement, as "depreciated cost new values" seems contradictory. 9. A new cost estimate for the proposed improvements that reflects the revised scope of work must be submitted. The value of the proposed improvements must be compared to the value of existing improvements to determine whether or not frontage improvements will be required. The appraisal's comparison of existing improvements to land value is irrelevant. �E L .

MEMO Date: December 6, 2000 To: Jon Jainga From: Debbie Maroon,P.E. Subject: Downstream Analysis for Proposed Federal Way Skate Park A Level 1 downstream analysis was performed per your request. Below please find a description of the downstream drainage system: Beginning at the northwest corner of the site the storm water would discharge to an existing ditch along 312th. The ditch is approximately 1-1/2 feet deep, 5 feet wide with 3 to 1 side slopes. The storm water would flow westerly for approximately 100 feet where it will enter a 12"concrete culvert under an existing driveway. The culvert is approximately 40 feet long and has a slope of approximately 2%. From the culvert the flow enters another ditch which is approximately 18"deep,and 5 feet wide. The flow continues in this ditch for approximately 260 feet where it enters a second 12"culvert under an existing driveway. Approximately 20 feet upstream from this culvert another 12"culvert discharges to the ditch. Scour is evident at the discharge point from the upstream culvert. The culvert under the driveway is approximately 60 feet long and is at a 2% slope. There is scouring at the end of the culvert. After exiting the culvert the flow enters a ditch which is 18-24"deep, 5 feet wide with 3 to 1 side slopes. This ditch continues for approximately 60 feet where the flow enters a 12"concrete culvert under an existing driveway. The culvert is approximately 40 feet long and has a slope of approximately 2%. Scouring is evident at the end of the culvert. After exiting the culvert the flow enters an 18- 24"deep, 5-foot wide ditch. The flow continues in this ditch for approximately 100' to a wooded area that drains to the south. The flow meanders through the woods for approximately 1000 feet before it reaches an apartment complex and a piped system.

The applicant proposes to construct a 9,600 square foot concrete skate park for use by skateboards and roller skates in the northeast corner of Steel Lake Park adjacent to South 312t'Street and 28th Avenue South. Zoning for the subject site is Single Family Residential (RS 7.2). This zoning district permits park uses pursuant to Federal Way City Code (FWCC) Section 22-646. The skate park is considered accessory to the park use and is subject to Process I,Director's Approval, as it does not meet the land use process exemptions in FWCC Section 22-32. 2. The proposed skate park is exempt from SEPA review pursuant to Washington Administrative Code(WAC) 197-11-800,"Categorical Exemptions." 3. Parking requirements for the skate park are on a case-by-case basis pursuant to FWCC Section 22-646.Additional parking stalls are not required with the new skate park as it is accessory to Steel Lake Park. The applicant has stated that existing parking west of the skate park site is adequate for skate park users,and includes passenger drop-off and bike racks.Access to the skate park will be provided from the parking lot west of the subject site.No pedestrian access from the rights-of-way to the skate park site shall be permitted. 4. Pursuant to FWCC Section 22-334,when a new and separate structure is being constructed on an already developed site,the applicant shall comply with all development regulations applicable to the geographic portion of the site on which the new structure and any related improvements are to be constructed. Since the skate park is considered an expansion of gross floor area and is separate from the other park buildings,the project must meet all current code requirements in the geographic portion of the site where the addition is being proposed. The project satisfies this requirement by providing perimeter landscaping in the geographic portion of the site where the project is proposed,pursuant to FWCC Section 22- 1566(b)(1). 5. A technical Information report(TIR)prepared by Earthtech,Inc.,March 2001, and revised April 6,2001,was submitted for the project. Storm drainage from the skate park site shall meet the King County Surface Water Design Manual(KCSWDM)and city amendments. The TIR states that runoff from the skate park will be dispersed to a trench west of the skate park site. Flows from this trench will be directed to an existing parking lot,which will allow existing down stream drainage conditions to remain unchanged. • c y 6. The submitted plans depict lawn restoration around the skate park and the removal of brush and blackberries along the eastern property line. Construction of the skate park necessitates removal of two significant evergreen trees. Removal of these trees will not require replacement under FWCC Section 22-1568(c)as less than 75 percent of the park's significant trees have been removed. The applicant submitted a landscape modification request to utilize existing perimeter landscaping to meet the perimeter landscape requirements.The requested modification serves to maintain visibility of the skate park site from the right of way and park offices located on the east side of 28`'Avenue South. The ability to provide surveillance into the skate park site is an important component of Crime Prevention Through Environmental Design(CPTED). In addition,the modification request is consistent with recommended code changes to park landscaping requirements contained in a proposed code amendment on park vegetation standards. The modification request to utilize existing landscaping along the north and east property line is approved. 7. Per FWCC Section 22-1632, subject applications for remodeling or expansion of existing developments shall meet only those provisions of design guidelines that are determined by the Director of Community Development Services to be reasonably related and applicable to the area of remodeling or expansion. The proposed skate park satisfies site design criteria by providing accessible pedestrian route of travel to and around the site,and seating is provided along numerous ledge areas. 8. Pursuant to FWCC Article IV, "Process I—Director's Approval,"and the forgoing findings, the proposal has been reviewed for consistency with all applicable zoning regulations including FWCC Section 22-646,"Public Parks"; FWCC Article IV,"Nonconformance"; FWCC Article XVII, "Landscaping"; and FWCC Article XIX, "Community Design Guidelines"; and is found to be consistent with the Federal Way Comprehensive Plan; all applicable provisions of the FWCC; and with the public health, safety, and welfare.
