Location and Site Context This Site Plan Review Pre-Submittal request applies to Tax Lot 5317 of Lane County Assessor's Map 17-02-35-32. The Gibson & Gibson, LLC site is approximately 32,236 square feet (0.74 acres) in size. This parcel as described will be referred to in this application as the subject site. Additionally, as permitted by the Oregon Department of Transportation (OOOT), the design proposes limited use of OOOT's properties along 69"' Street for access, vehicular circulation, landscaping and existing utilities. (Reference attached e-mail from Debbi Rich, OOOT Property Agent, to Kristen Taylor dated January 29, 2009, including: Draft License for Ingress and Egress, Legal Description of OOOT Portion of OLD 69th Street Right-of-Way; and Exhibit A, Statutory Warranty Deed.) The OOOT parcels are approximately 3,687 square. feet (0.085 acres) in size. The subject site is located on the northwest side of the 69th Street and Main Street intersection. Main Street (McKenzie Highway 126) is classified as a principal arterial and 69th Street is classified as a major collector. The subject site is located within the Springfield City limits and Urban Growth Boundary. The Gibson & Gibson, LLC property is zoned Neighborhood Commercial (NC) and currently developed with a Oari Mart convenience store and a coffee kiosk. The OOOT property located directly east of the site is zoned NC and currently developed with existing asphalt, 6" curb and landscape bed adjacent to OOOT's Tax Lot 2101. The OOOT parcel, Tax Lot 2101 (1,307 square feet), located along 69th Street is zoned Low Density Residential (LOR) and is currently developed with landscaping. . The properties located to the north, south, east and west of the subject site are zoned Low Density Residential and developed primarily with single family residential homes. The proposed development site is serviced nearby via Lane Transit ~istrict (L TO) Route 11. The nearest bus stops that are regularly serviced by this route are . adjacent to the site on Main Street near the intersection of 69th Street and Main Street. B. Existing Conditions and Site Access The subject site is relatively flat and will take primary access to the public road system via existing driveways located on 69th Street and Main Street. The property is determined to be outside of the 500-year floodplain. . . 'City of Springfield. . Site Plan Review Pre-Su~ittal Application September 29,2009 Page 50f 18 . ODOT-owned fee-title properties separate most of the site's frontage from the 69th Street public right-of-way. ODOT has given preliminary indication that they will issue a License for Ingress and Egress for the project to maintain the existing entry across their property via the existing 69th Street driveway for access, vehicular circulation, landscaping and existing utilities. ODOT's issuance of the License for Ingress and Egress is subject to the City of Springfield's approval of access to 69th. Street as noted in attached e-mail from Debbi Rich, ODOT PropertyAgent, to Kristen Taylor dated January 29, 2009. The existing landscaping on the site will be enhanced with new landscaping consistent with the current development code standards. The existing trees on- site and street trees will remain and tree protection measures will be observed as needed to protect the trees and roots systems during construction. . Reference the planting plan for details. III. land Use History The subject site was an[\exed into the City of Springfield in 1960. As stated above, the subject site is located within the Springfield City Limits and Urban Growth Boundary. ,It is zoned Neighborhood Commercial (NC). . IV. Approval Criteria - Site plan Review Supporting Facts and Finding~ . This section is organized by the applicable approval criteria per SDC 5.17-125. Applicable approval criteria are outlined in bold italics below, followed by proposed findings in normal text. A. The zoning is consistent with the Metro Plan diagram, and/or the applicable Refinement Plan diagram, Plan District map, and Conceptual Development Plan. Findings: Per the Eugene-Springfield Metropolitan Area General Plan. Plan Diagram, the subject property falls within the Urban Growth Boundary .and the Metro Plan Boundary. The subject site is clearly designated Low Density Residential on the 2004 Metro Plan Diagram. However, per the Metro Plan Section G, Metro Plan Diagram, the second paragraph under Land Use Designations, states that "Certain land uses are not individually of metropolitan- wide significance in terms of size or location because of their special nature or limited extent. Therefore, it is not advisable to account for most of them on the Metro Plan Diagram. The Diagram's depiction of land use designations is not intended to invalidate local zoning or land uses which are not sufficiently intensive or large enough to be included in the Metro Plan Diagram." It was determined in past City of Springfield land use and building permit applications City of Springfield Site Plan Review Pre-Submittal Application September 29, 2009 . Page 6 of 18 . . . . that this property is not sufficiently large enough to be included in the Metro Plan Diagram. The existing NC zoning is consistent with the Springfield Zoning Map, which is the guiding zoning document for this property. The subject site falls within the Thurston Area, which does not have an adopted Refinement Plan or Plan ~istrict Map. There are no other relevant land use planning documents for this site. The proposed use is consistent with the Springfield Development Code (SOC) and as stated above, consistent with the Springfield Zoning Map, the guiding zoning document for this property. Generally, retail sales and specifically, convenience stores, are permitted uses in the NC zoning district subject to Site Plan Review approval. The tenants for the proposed additional building area have not yet been identified. However, the uses will be permitted uses in the NC zoning district subject to review at the time of tenant infi\l building permit submittal. Therefore, the zoning and proposed development is consistent with this criterion. B. Capacity requirements of public and private facilities, including but not limited to, water and electricity; sanitary sewer and stormwater management facilities; and streets and traffic safety controls shall not be exceeded and the pubfic improvements shall be avaifabfe to serve the site at the time of development, unfess otherwise provided for by this Code and other appficable regulations. The Public Works director or a utility provider shall determine capacity issues. Findings: The applicant is proposing to construct a building addition of approximately 4,600 square feet to the existing 2,900-square-foot Oari Mart convenience store building as well as update the site infrastructure and parking associated with the addition on NC-zoned land with adequate public and private facilities. Reference the attached civil engineering drawings for details on existing and proposed facilities. Per SOC 4.3-125, all private utilities on the proposed development site will be placed underground whenever possible. There are no streets or public improvements proposed as part of this development. The existing driveways on 69th Street and Main Street are proposed to remain unchanged: There is an existing public utility easement, which presently covers the entire eastern end of the subject site and the OOOT property. Within this easement on the subject site, there is, an existing public 8" water main and gas line located beside each other located adjacent to the OOOT property running in the,north- south direction. There is also a public 66" stormwater main and gas line that also runs in the north-south direction along the eastern edge of the subject site and OOOT site. The owner proposes to revise the existing blanket public utility easement in this area of the subject site so the western edge of the easement shifts to the east by only about 8 to 10 feet to more appropriately define the area . City of Springfield . Site Plan Review pre-Sul::imittal Application September 29,2009 Page 7 of 18 . ...~. . .....: required for the existing utilities. The owner has provided correspondence and letters of consent for a proposed revised easement configuration by Springfield Utility Board (SUB) for the water line, and the City of Springfield'. Reference the attached Existing Conditions Plan for details regarding the exiting public utility easement and ODOT property locations. Reference attached preliminary letters from Clayton McEachern, the City 6f Springfield, and Bart E. McKee, Springfield Utility Board. Also reference the existing and proposed draft public utility easement descriptions. . The proposal has adequate water service available from an existing 8" public water main located along Main Street. There is an existing lateral stub off this main just east of the existing Main Street driveway for the private water lines. There is also an existing 8" public water main off the Main Street public water main that runs north-south through the subject property, which is located within an existing public utility easement. There is an existing overhead electric line running north-south adjacent to the site's eastern property line, which provides. adequate capacity to serve the proposed development. There is an existing private underground electrical line on-site that serves the existing building and has adequate capacity for the proposed addition. There are two existing sewer service stubs provided in the northwest portion of the subject site, which are and can be utilized to convey sewage from the site to the 12" public sanitary sewer main which runs within an existing public utility easement along the north line of the subject site and conveys the sewage westerly. The existing public sanitary sewer has adequate capacity to serve the development's needs. As noted above there are two existing gas lines located on the subject site within a utility easement that can adequately serve the subject site. The existing building on the site currently does not utilize natural gas. There is an existing 8" storm pipe located along the north side of Main Street with an existing 8" storm lateral stubbed to the subject site's southern property line. The existing public stormwater main has adequate capacity to serve the 1 Please note that the original discussions with these agencies involved replacing the blanket easement with minimal required easements for each of the public utilities (Le., ten-feet~wide for the SUB water line). Although the agencies contacted are in general support, it became apparent that this approach was not necessary. The current proposal maintains the blanket eilsement and only shifts the western edge of the easement to the east to more appropriately define the area required for the existing utilities. Also note that TBG has unsuccessfully attempted several times to contact NW Natural. The owner realizes that all affected utility companies will need to approve the proposed change. The proposed building [addition has been moved to sit outside of the required minimum 10'-011 from the centerline of the 8" wate~1ine in response to Bart McKee's letter. City of Springfield Site Plan Review Pre-Submittal Application September 29, 2009 Page 8 of 18 . . . . development's needs. See the attached Stormwater Management System Plan for information regarding the required on-site stormwater management system proposal. As noted above, ODOT -owned fee-title properties separate most of the site's frontage from the 69th Street public right-of-way. ODOT has given preliminary indication that they will issue a License for Ingress and Egress for the project to maintain the existing entry across their property via the existing 69th Street driveway for access, vehicular circulation, landscaping and existing utilities. ODOT's issuance of the License for Ingress and Egress is subject to the City of Springfield's approval of access to 69th Street as noted in attached e-mail from Debbi Rich, ODOT Property Agent, to Kristen Taylor dated January 29, 2009. The existing public street and traffic safety control systems will not be exceeded with the addition of the proposed development and are available to serve the site at the time of development. As noted above, per Public Works Staff, the proposed development does not require a Transportation Impact Study. As demonstrated above as well as in the drawings and referenced attachments, capacity requirements of public and private facilities, including but not limited to, water and electricity; sanitary sewer and stormwater management facilities; and streets and traffic safety 'controls have not been exceeded and the public improvements are available to serve the site at the time of development. Therefore, the proposed development is consistent with this criterion. C. The proposed development shall comply with all applicable public and private design and construction standards contained in this Code and other applicable regulations. SDC 3.2-300 NC Zoning District Development Standards: Findings: The tenants for the proposed multitenant building addition have not yet been identified. However, all uses will be consistent with the allowed use categories listed under the NC base zone per SDC 3.2-310 at the time of tenant infill building permit submittal. Specifically, the development complies with the NC Development Standards (SDC 3.2-300 NC base zone) as follows (reference the attached Site Plan and Exterior Elevation drawings for details): . The Development Standards regarding area and frontage required under SDC 3.2-315 do not apply for three reasons. First, because the subject site was created prior to 1982, it exceeds the minimum lot size of 6,000 square feet; it is about 32,236 square feet. Second, the minimum lot size standard of SDC . City of Springfield . Site Plan Review Pre-Su~ittal Application September 29,2009 Page 9 of 18 . 3.2-3150 is a standard imposed for the creation of new lots or parcels. The proposed development does not include partitioning pr subdividing the subject property. Third, this standard is not a design or construction standard, and therefore not applicable. . Per SDC 3.2-315, the maximum lot coverage for a lot that is less than one acre is 35 percent. The proposed lot coverage is about 25 percent, which falls well below the required maximum. . Per SDC 3.2-315, the'minimum landscaping area shall not be less than 20 percent of the total development area. The proposed landscaping area is about 21 percent, which meets the required minimum. .' Per SDC 3.2-315, the maximum parking, loading and vehicular circulation area coverage is 45 percent. The proposed parking, loading and vehicular circulation area coverage is 45 percent, which meets the required minimum. . Per SDC 3.2-315, the minimum building front yard setback in the NC zone is 10'-0". and parking and driveway front yard setbacks are 7'-0". The buildings, parking and driveways either meet or exceed the required front yard setbacks along Main Street and 69th Street. Note that where the subject site is located adjacent to the ODOT property without an identified ODOT Tax Lot number, the }'-O" parking and driveway front yard setback is met on the ODOT property .along 69th Street as permitted by ODOT for this development. (Reference .attached e-mail from Debbi Rich,ODOTPropertyAgent,to Kristen Taylor dated January 29,2009, including: Draft License for Ingress and Egress, Legal Description of ODOT Portion of OLD 69th Street Right-of-Way; and Exhibit A, Statutory Warranty Deed.) The minimum 7'-0" parking front yard setback is met on the subject site where directly adjacent to ODOT Tax Lot2101. . . The .interior and rear yard building setback is 10'-0" and the parking and driveway interior and rear yard setbacks are 7'-0". The buildings, parking and driveways either meet or exceed the required minimum 7'-0" setback from interior and rear property lines as required per SDC 3.2-315. . The single-story building is compatible with adjacent development. The proposed development site is within a 20'-0" height limitation zone. The proposed building height is 20'-0," which meets the required height restriction. . On-site pedestrian circulation has been provided, which connects the neighborhood commercial building tenant entrances to the trash area and public sidewalk on Main Street. The site design either meets or exceeds the required ADA minimum 3'-0" wide clear pedestrian pathway to accommodate pedestrian circulation on-site. (The approximate 7'-0" wide walkway adjacent to the building's front fa<;ade accommodates 2'-0" vehicle bumper overhangs.) . No outdoor merchandise display areas are proposed. . No drive-through facilities are proposed. City of Springfield Site Plan Review Pre-Submittal Application September 29, 2009 . . . Page 10 of 18 . . . .

Considering these findings and the drawings submitted herewith, this standard is met. 4.3-130 Water Service and Fire Protection: Findings: As noted above, the proposal has adequate water service available from an existing 8" public water main located along Main Street. There is an existing lateral stub off tDis main just east of the existing Main Street driveway for the private water lines. There is also an existing 8" public water main off the Main Street public water main that runs north-south through the subject property, which is located within an existing public utility easement. There is an existing fire hydrant located adjacent to the site along Main Street near the proposed pedestrian walkway connecting to the public sidewalk. The existing fire hydrant can adequately meet the fire protection needs of the development. Therefore, this criterion is met. 4.3-13S'Major Electrical Power Transmission tines and 4.3-140 Public Easements: Findings: There is an existing overhead electric line running north-south adjacent to the site's eastern property line, which provides adequate capacity to serve the proposed development. There is an existing private underground electrical line on-site that serves the existing building and has adequate capacity for the proposed addition. Therefore, this criterion is met. 4.3-145 Wireless Telecommunications Systems Facilities: Findings: There are no wireless telecommunication system facilities proposed in this development. Therefore, this criterion is not applicable. 4.4-105 Landscaping: Findings: The landscape architecture drawings show landscaping which meets or exceeds the NC zone and parking lot landscape requirements for the entire development site per SDC 4.4-105 and SOC 4.6-125(6)(1)., Landscaping is provided in all required setback areas in accordance with the Landscape Standards under SOC 4.4-1 05(E), (F)(l) and (G). Note that where the subject site is located adjacent to the OOOT property without an identified OOOT Tax Lot number, the parking and driveway front yard setback is met on the OOOT property along 69th Street and the existing landscaping is proposed to remain. (Reference attached e-mail from Oebbi Rich, ODOT Property Agent, to Kristen City of Springfield Site Plan Review Pre-Submittal Applicati()n September 29, 2009 Page 14 of 18 . . Taylor dated January 29, 2009, including: Draft License for Ingress and Egress, Legal Description of ODOT Portion of OLD 69th Street Right-of-Way; and Exhibit A, Statutory Warranty Deed.) The landscaping required in the parking front yard setback is met on the subject site where directly adjacent to ODOT Tax Lot 2101. . . In addition, per SDC 4.6-125(B)(1), the proposed updated parking area sufficient to meet the requirements of the minimum parking for the proposed addition is designed so that every seventh space is developed as a landscape separator between spaces. Located along Main Street, there are 8 existing vehicle parking spaces associated with the existing building and use that are proposed to remain, therefore, these existing parking spaces are not required to meet 4.6-125(B)(1). However, the proposal does provide a new landscape bed between the existing driveway entrance and this row of existing parking spaces to heighten entryway visibility and improve parking area circulation. As noted on the landscape architecture drawings, landscaping will be installed per SDC 4.4-105(1). These findings and the attached landscape architecture planting plan, schedules and details, demonstrate that the landscaping requirements have been met. 4.4-110 Screening: Findings: Adjacent to the residential property to the north and west, screening is provided due to a commercial district abutting a residential district and the proposal of trash receptacles in accordance with SDC 4.4-11 O(A)(l) and (4), and SDC 4.4-11 O(B)(l) and (3). There is an existing 6'-0" high slatted chain-link fence along the northern property line that is proposed to remain.. Along the western property line, there is an existing about 4'-0" high chain-link fence on the neighbor's property. In order to meet the screening standards, there is a new 6'-0" high slatted chain-link fence proposed on the subject site along the western property line. To enhance the existing structural screening along the northern property line and the new structural screening along the western property line, landscaping has been added along these property lines to provide additional vegetative screening to reduce the impact of the commercial developrnent on the neighboring residential properties. The owner requests that the Director approve this existing and new slatted chain-link fence as allowed under SDC 4.4- 110(B)(3)(b). The proposed outdoor trash receptacles are structural screened with a 6'-0" high masonry wall as well vegetated screening per SDC 4.4-11 0(B)(3)(c). (Reference the attached architecture and landscape architecture drawings for details.) Therefore, this criterion is met. . . City of Springfield . Site Plan Review Pre-Submittal Application September 29, 2009 Page 15 of 18 . " . ;, ,. , . .. 4.4-115 Fences: Findings: As noted above, located adjacent to the LOR-zoned properties, there is a screening fe~ce proposed along the western 'property line and an existing fence along the northern property line. Per Table 4.4-1, the base height of a fence shall be 8'-0". maximum. The existing slatted chain-link fence along the northern property line and the new proposed slatted chain-link fence along the western property li.ne are both 6'-0," which fall below the required maximum. Exact fence details shall be proposed at the time of building permit consistent with the requirements outlined under SOC 4.4-115. Therefore, this criterion is met. 4.5-100 On-Site Lighting Standards: Findings: All proposed site lighting will be installed in compliance with the requirements of this code section. All proposed exterior light fixtures will be shielded so that direct glare and reflection are contained within the boundaries of the property, and directed downward and away from abutting properties and public rights:'of-way. The proposed site lighting is the minimum illumination necessary for pedestrian and employee safety, on-site parking and loading areas. Exact outdoor building lighting will be proposed at the time of building permit submittal in accordance with this code section. Parking lot light fixtures are proposed to be a maximum height of 20'-0", which is less than the required maximum 25'-0" per SOC 4.5c 11 O(B)(l). The parking lot light fixture proposed within .50'-0" of the residential district to the west is a maximum height of 12'-0 per SOC. 4.5-11 0(B)(2)(b). These findings, the Site Plan and attached proposed Parking Lot'Light Fixture Specifications demonstrate that this criterion is met. 4.6-105 through 4.6-125 Vehicle Parking: Findings: Vehicle and bicycle parking calculations are based on assumptions of a possible tenant mix. Per the assumed tenant uses, a minimum of 24 off-street parking spaces are required per Table 4.6-2 (see vehicle parking calculations on Sheet Tl). The applicant is proposing to provide 23 standard parking spaces and 1 accessible space. The applicant proposes a parking lot design in compliance with SOC 4.6-115; all stall widths are 9'-0" wide and 18'-0" in length including a 2'-0" bumper overhang> over landscaping beds and walkways (reference drawings for specific locations). The dimensions and proposed striping of the parking spaces and drive aisles meet the parking area standards per SOC, 4.6-115-120. These findings, together with the architecture and civil engineering drawings, demonstrate that these standards have been met. 2 The existing 8 spaces along Main Street are 9'_0" wide and 18'-0" in length including a wheel stop so the bumper overhang is only 1 '-0' over the existing landscaping bed so the 7'-0" minimum parking front yard setback is met. City of Springfield Site Plan Review Pre-Submittal Application September 29,2009 Page 16 of 18 . . 4.6-130 through 4.6-135 Loading Areas: Findings: On the north side of the building, there is a proposed delivery and loading area outside of the required setbacks. The total proposed on-site loading area is about 560 square feet for approximately 7,919 square feet of total building area, which exceeds the required 250 square feet of minimum loading area for buildings 5,000 to 20,000 square feet per SDC 4.6-135(C). Both loading areas are about 10'-0" wide and about 35'-0" long, which meet the minimum dimensions of 10'-0" wide and 25'-0" long per SDC 4.6-135(0). Therefore, this criterion is met. 4.6-140 through 4.6-150 Bicycle Parking: Findings: The proposed bicycle parking spaces, location and facility design complies with SDC 4.4-145-150. As noted above, vehicle and bicycle parking calculations are based on assumptions of a possible tenant mix. The short-term and long-term bicycle parking spaces provided based on those assumptions exceeds the number required (reference Sheet T1 for bicycle parking calculations). The 4 unsheltered short-term bicycle parking spaces are located along the on-site pedestrian walkway system with ramps that connects to Main Street. The proposed racks are hitching posts or staple racks designed and dimensioned per Figure 4.6-B (reference attached Detail 2/A 1 for the typical short-term bicycle parking detail). The short-term spaces are located on the east side of the building so they are visible form both Main Street and 69th Street. Correspondingly, lawn is provided in the landscape bed adjacent to the bicycle parking so as not to obscure the visibility of the bicycle racks from Main Street. The long-term bicycle parking spaces will be located inside individual tenant spaces in a secure location, which will be in compliance with SDC 4.4-145-150 at the time of tenant infill building permit submittal. Therefore, this criterion is met. D. Parking areas and ingress-egress points have been designed to: facilitate vehicular traffic, bicycle and pedestrian safety to avoid congestion; provide connectivity within the development area and to adjacent residential areas, transit stops, neighborhood activity centers, and commercial, industrial and public areas; minimize driveways on arterial and collector streets as specified in this Code or other applicable regulations and comply with the ODOT access management standards for State highways. Findings: The orientation of the building serves to maximize efficiency for access, on-site circulation and function while minimizing impact to the adjacent properties. The site plan is organized so that the main access points to the building are located directly off of the existing driveways on Main Street and 69th Street. The majority of the building activity occurs within the interior of the site . . . City of Springfield . Site Plan Review Pre-Su~ittal Application September 29, 2009 Page 1 7 of 18.. . ". between the building and Main Street. There is a proposed continuous on-site pedestrian walkway system connecting the building to Main Street. As rioted. above, the site plan shows on-site circulation for pedestrians, bicycles and vehicles as required by the Springfield Development Code. Designated on- site pedestrian circulation is provided for employees and customers of the tenant businesses from the adjacent Main Street public right-of-way to all building entrances. On-site pedestrian and bicycle access is provided through the parking and drive aisles by a clearly marked, striped walkways, The existing public sidewalk anc! bike lane/route on Main Street and 69th Street provide access to adjacent and nearby residential areas. The closest transit stops to the site are located on Main Street, which serve the 11 Thurston bus route. As noted above, ODOT-owned fee-title properties sep"arate most of the site's frontage from the 69th Street public right-of-way. OOOT has given preliminary indication that they will issue a License for Ingress and Egress for the project to maintai~ "the" existing entry across their property' via 'the existing 69th Street driveway for access, vehicular circulation, landscaping and existing utilities. ODOT's issuance of the License for Ingress and Egress is subject to the City of Springfield's approval of access to 69th Street as noted in attached e-mail from Oebbi Rich, 6D~:n Property Agent, to Kristen Taylor dated January 29, 2009. The existing' driveways on 69th Street and Main Street comply with City of Springfield and ODOT access management standards. Parking areas and existing ingress-egress points have been designed to safely facilitate vehicular traffic, bicycle and pedestrian circulation and avoid congestion as well as provide connectivity' within the development area and to adjacent residential areas. Therefore, ~his criterion is met. E. Physical features, including, but not limited to: steep slopes with unstable soil or geologic conditions; areas with susceptibility of flooding; significant clusters of trees and shrubs; watercourses shown on the WQLW Map and their associated riparian areas; wetlands; rock outcroppings; open spaces; and areas of historic and/or archaeological significance, as may be specified in Section 3.3-900 or ORS 97.740-760, 358.905-955 and 390,235-240, shall be protected'as specified in this Code or in State or Federal law. The subject site is flat and currently developed, The general soil type description is pengra-urban land complex specified in the Solis Survey of Lane County. The Soils Survey indicates that the proposed development area has stable soils and does not have a high water table. Therefore, a Geotechnical Report is not required for the Site Plan Review process. A Geotechnical Report will be prepared as needed at the time of building permit submittal for the purposes of building structural design and construction. City of Springfield Site plan Review Pre-Submittal t',pplication September 29, 2009 ' Page 18 of 18 . . , " I'. There are no significant clusters of existing trees and shrubs on the site. Additionally, the site does not have any watercourses and associated riparian areas, wetlands, rock outcroppings, open spaces or areas of historic and/or archaeological significance as specified in Section 3.3-900 or ORS 97.740-760, 358.905-955 and 390.235-240. 'Furthermore, the site is located within a FEMA Zone X flood hazard zone (an area determined to be outside of the 500-year flood plain). Therefore, the site will not be a significant risk to public health and safety in terms of stormwater control or flood hazard. As the site is flat and is located outside the 500-year flood zone, slope failure and soil erosion are not concerns associated with this site. The site does not have physical features as outlined above that require protection as specified in this Code or in State or Federal law, therefore, this criterion is met. V. Conclusion Based on the information and findings contained in this written statement, associated attachments and drawings, the proposed Site Plan Review meets the criteria of approval contained in the Springfield Development Code.. Therefore, the applicant requests that the Director approve the proposal as presented. Both the applicant and the applicant's representative are available for questions as necessary.

We have no way of knowing how this property ended up being combined in to this tax lot when the street was vacated. I think the easement idea has been fairly well discussed. ODOT prefers not to encumber property with an easement, and if an easement were to be granted it would have to be at market value, as required by statute. We do have one other possibility, a License for Ingress and Egress, which I will be happy to discuss with my manager. As soon as I have an answer from him, I will let you know. If you have any questions in the meantime, please let me know.

Thank you once again for your response. I have a few follow up questions .for you. Thank you for taking time to iook more closely at this project. If the owner decides to request an easement to have continued access across ODOT's property .for the purposes of satisfying the City requirements, can this be done without a costto my client considering the circumstances and history of this parcel? My client just wants to construct a small addition to his existing building. The addition and minor site improvements do not occur on the ODOT parcel. The ODOT parcel will remain unchanged. My client would just like to maintain the current access off of 69th. It also appears that my client has been paying taxes on the ODOT parcel for many years due to the misidentified ownership of this small parcel until recentiy. It seems like undue hardship to require my client to pay for an easement or purchase the parcel to maintain access across this property. I recognize that the parcel is surpius so is it possible to engage in a revocable easement? Thank you once again.

Although this property is not assigned a tax lot #, it is not part of the McKenzie Highway's right-of-way system. It is also available to surplus, which furthermore identifies it as none operating right of way. It appears that to obtain legal access through the property an easement would be required.

ODOT owns Assessor's Map 17-02-35-32 Tax Lot 2101 east of my client's property. I have attached a drawing with the highlighted area of OOOT owned right-of-way sitting directly adjacent to my client's property that was the piece under question of ownership for clarity (highlighted in yellow) - it has been confirmed that OOOT owns this 9/25/2009 Message . . Page 4 of 4 (.~I. ".. ..' , '. .\. ,;" oddly shaped piece. As I said on the phone, the owner would like to add onto their existing building on their property. The ' . development would not impact the ODOT owned property. However, they would like to continue to access their property through the ODOT right-of-way parcel and 69th Ave driveway. Now that the city is clear who owns the property, they would like something from ODOT that allows access through ODOT's property such as an access permit as suggested by Debbie below (note that my client is not interested in purchasing or leasing the land at this point). Here is correspondence that our civil engineer had with Debbie Rich. I spoke with Debbie Rich of ODOT a few times over the last 2 weeks regarding the possibility of obtaining an access easement over the ODOT property at 69th. She got back to me yesterday and stated that she had discussed this with other ODOT staff, and the cost for the easement would probably be the same as purchasing the land. Debbie suggested maybe the Gibson's could explore leasing the land, as ODOT does not like to grant . easements. I explained to Debbie that the City of Springfield is requesting the easement and Debbie said that she has ran into this' before with other City governments, and she suggested maybe getting an access permit from the local ODOT District Office in Springfield. This permit has successfully satisfied a requirement for an easement by a City government in the past. The ODOT District 5 Office in Springfield is 726-2552. (Here is an ODOT file number that was associated to the potential purchase exploration, which might be helpful #MS00020.) Lynn, do you' think it would be possible to request an access permit for the continued access across ODOT property? Can you please explain the process andtimeline, if this is possible. It is my understanding that the city would be fine with this approach. ' Thanks and enjoy the snow:) Please let me know if you have any questions.

It appears that the easement was created when 69th St was relocated to the east and several utilities that were previously in the city owned ROW for 69th St were not relocated. The. only utility line in the easement that the city has interest in is the 66 storm drain line that drains to the north through the easement. A Development Issues Meeting (DIM) is recommended for questions such as this. Through this process the city can provide definitive answers on this or any other questions or previously unknown circumstances that could affect any potential development on the site. The city will also seek input from all parties affected by the development (such as SUB, ODOT, Willamalane, and other private utilities). Upon preliminary inspection, a 20' wide easement centered on the surveyed location of the line would probably be acceptable. Based on the approximate location of the storm drain line shown in the city GIS maps that the east portion of the easement would overlap with the existing ODOT owned property and city owned ROW for 69th St. The western portion ofthe easement would intrude into the parking lot of the existing business (Dari-Mart) on the site. Additionally, any other utilities located within this] eas~ment will need to have a concurrence letter from the concerned utility or owner to allow the 'easement adjustment. The easement relocation can be handled through the typical site development submittal process or as an independent submittal. City planning staff can provide assistance with the details of the submittal process.

OVERVIEW 1.0 INTRODUCTION The subject property involved in the proposed development is a gently sloping 0.74-acre development site, currently developed with a Dari Mart and coffee stand. The site is on Tax Lot 5317 Assessor's Map 17-02-35-32. The site is bounded on the East by 69th Street, bounded on the North and West by adjacent lots, and bounded on the South by Main Street (McKenzie Highway). A 3,700 square foot-retail and 900 square foot additional buildings are proposed on _ _Jl1.L~ubj~LQ!"-'!p'(lr:tx,._ cOl!!Pl(l!t:_~wjQ1_<ljJ~J9ng-.1()t,_~'!n.,tt.~!L~t:..\I1er~L_aIlcL stoEm _.<fraill,!g,". _ infrastructure to carry runoff from the development to the existing public storm system. 3,177 ~quare feet of new or replaced non building surface will be added to site. Seventy-nine percent of the new non-building runoff will be treated with a vegetated swale. Stormwater runoff from the west paved area on the site will be directed through a curb cut to the vegetated swale. Catch basins equipped with filters and oil/water separators will be placed in the swale for catching overflow. Roof and sidewalk run-off is routed to the existing system on the site. The vegetated swale will filter pollutants and sediments from the run-off and the planting of trees within the swale and detention pond areas will further pre-treat the stormwater runoff by reducing the temperature of the runoff before it enters the public system. Hydrologic calculations to determine the existing (pre-development) and proposed (post- development) runoff amounts are included, as are hydraulic calculations to determine pipe sizing, and calculations to determine the sizing of the proposed vegetated swale. A "Stormwater Management System Scope of Work" sheet was submitted to the City for the proposed development. The scoping sheet states that a downstream analysis of the receiving system is not required for this report. Mid-Level Development Study is required using Unit Hydrograph methods. 2.0 PURPOSE The purpose of this report is to attempt to comply with the requirements of Article 32.11 0 _ Stormwater Management of the Springfield Development Code, and the Springfield Public Works Engineering Design Standards and Procedures, dated April 2006. . . HYDROLOGIC AND HYDRAULIC CALCULATIONS 69TH & MAIN ADDITION: 1.0 PURPOSE The purpose of these hydrologic and hydraulic calculations is to determine the runoff flows from the subject property for both pre-development and post-development conditions, and to verifY pipe and swale sizing for the proposed development. :2.0.CALCJJLAIlQN.IVIETlIQilS The Santa Barbara Urban Hydrograph (SBUH) method was used to determine the pre- development and post-development runoff from the site. Excel software was used to perform the specific calculations. The input variables and resulting flow rates are included in Appendix A. The flow calculated from the SBUH was proportioned by area and used to size the drainage pipes for the post-development runoff from the site (2-year and 25-year event). Time of Concentration: The Time of Concentration for the pre-development conditions was determined using an initial time of. 10 minutes, and then adding the calculated travel time for pipe flow, gutter-flow, and flow to the existing catch .basin from the most remote point in the basin. The pipe flow calculations were determined using Manning's Equation for pipe flow. Specific Time of Concentration calculations for the pre-development conditions are included in Appendix A. The Time of Concentration for the post-development conditions was provided by the City of Springfield staff to be 10 minutes. As shown in Appendix A: . The Time of Concentration for the pre-development (existing) conditions was calculated to be 10.9 minutes. 3.0 PIPE SIZING The pipe sizing calculations is included in Appendix A. Required flows to the swale and the existing 8-inch stormwater pipe were proportioned from the site peak-flow calculation and areas being drained. A Manning's n value of n = 0.013 was used for PVC pipes per City of Springfield Engineering Design Standards manual, achieving a minimum cleansing velocity 3.0 ft/s for all new pipes. Existing pipes were checked for capacity using the same Manning's n value. . .-;nlSWALE/CONVEYANCE .. _,..,......_ - .. _;-~..-.c:, ~."_. .

",_--'''0.,-.,. --'",'.-'O"'''--'''~''__.",","_:''_ A vegetated swale was chosen as the best method for pre-treating the stormwater runoff by allowing for natural percolation. The vegetation will also aid in cooling the water prior to disposal in the public system. Swale design guidelines were obtained from the Bureau of Environmental Services-City of Portland (BES) manual. A detail from the BES manual is . . included in Appendix B, while the specific dimensions and layout of the swale design is shown on the' Grading Plan, Sheet C3. . Form SIM from the BES manual was used to calculate the necessary swale dimensions for the post-development runoff. Tree credits were taken as applicable from the landscape architect's plans. The Form SIMs are included as Appendix B. 5.0 CONCLUSION The preliminary stormwater drainage facilities planned for the proposed development will be adeqiiate"fo..coiiveTrunoffofromollie'proposeaaevelopmeiit.

In large stomi events, the swale is provided with an overflow to direct floodwaters to the existing stormwater system located on the property leading to the Main Street storm system, and away from the subject site and adjacent properties. .. .~.-,-..",~, :.,....,-.....
