The location of the permanent traffic control signs are shown in the Public Improvement Plans (PIP) Transportation drawings. This condition will be met at the time of the final acceptance of the public improvements. The Final Plat and PIP have been revised to show River Heights Drive extending to the eastern boundary of the subdivision. This condition has been met. The Final Plat and the PIP have been revised to show Vitus Lane extending from River Heights Drive to the eastern boundary of the project between tax lots 601 and 600. This condition has been met. Because the staff report did not reference specific sub-sections of Section 7.05 to address, the Applicant has addressed all sub-sections of Section 7.05 of the EDSPM herein. Section 7.05 of the EDSPM states 7.05.1 Temporary Dead End Slreels The length of a temporary dead end street (due to an approved phasing sequence within a development) shall not exceed 1000 feet. Temporary dead end streets which are greater in length than allowed by the City Development Code shall not be allowed without a plan and financial guarantee (bond) that the street will be completed through to another outlet point within three years. The temporary dead end street' shall be constructed with appropriate turnarounds for emergency vehicles. In addition, PRE.$UBMIlTAL REC'D River Heights Final Plat Application Narrative Pag~JU<i12'J 1 2009 . . temporary dead end streets shall be provided with a temporary, secondary emergeno/ vehicle access until the completion of the street provides a permanent secondary access. The only dead end street included in the project is Quarry Ridge Drive. ACity standard cul-de- sac turn-around has been included in the PIP drawings. Right-of-way will be dedicated to the site boundary line. This condition is met. 7.05.2 Right-of-Way Dedications Right-ofway shall be dedicated as required to allow future street connection to abutting lands along the boundary of the site. These shall be public streets and shall be constructed in conjunction with the development. This condition has been met as stated in the repose to Condition 2 and Condition 3. 7.05.3 Slope Easements Slope easements shall be dedicated along streets as needed for operation and maintenance purposes proportionate to the angle of repose of slopes and as needed for slope stability and drainage considerations. . . . This condition will be met, adequate slope easements will be provided on the fmalplat. 7.05.4 Local Street Right-of-Way . '. Right-ofways shall be dedicated for local streets according to SDC Section 32.020, Table 32-1 of the Springfield Development Code. This condition will be met, all street right-of-ways will be dedicated with the recording of the final plat and will be the required 40- feet in width. 7.05.5 Field Measured Cross Sections Submittals of field measured cross sections, extending a minimum of 20 feet beyond fill and/or excavation limits, showing the proposed street and the existing ground elevations shall be submitted with each set of the construction plans for streets. This condition has been met, cross-sections based on field gathered topography are included in the PIP drawings. 7.05.6 Details and Typical Cross Sections Details and typical cross sections with slope control measures shall be submitted with each phase of development. The development application shall also indicate the location and under what conditions retaining walls will be constructed. A registered engineer shall design all retaining structures exceeding 30 inches in height. This condition has been met. Sheet G2 of the PIP drawings includes the typical street cross- sections. The Grading Plan included with the PIP drawings includes slope control details. Any retaining walls constructed as part of the PIP process or home building will be designed by an Oregon Registered Engineer. 7.05.7 Secondary Access Secondary access to each phase of a development shall be provided for police and fire response. This condition is met. The project includes access from V-Street and from 37th Street. 7.05.8 Geometry 7.05.8.A Basic Geometry Unless otherwise authorized by the City Engineer, standard basic engineering geometry shall be adhered to. For specific design standards, the engineer shall employ the latest edition of the AASHTO 's A Policy on Geometric Design of Highways and Streets. The location, width and grade of streets shall be considered in their relation to existing and planned streets, to topographical conditions, and to the planned use of land to be served by the streets. Grades, tangents, curves and intersection angles shall be appropriate for the traffic to be carried, considering the terrain. Construction specifications and design standards for private streets shall be the same as for public streets. PRE-SUBMITTAL REC'D JUL 3 1 2009 River Heights Final Plat Application Narrative Page 4 of23 . . This condition has been met. The streets proposed in the PIP drawings have been designed to balance the requirements of providing access to the proposed lots, traversing the required topography, and meeting the design requirement for very low volume residential streets. 7.05.8.B Comhillalloll Vertical alld Horlzolltal Curves Whenever a vertical curve, with an algebraic difference in grade of five percent or more, is combined with a horizontal curve, the engineer shall provide the City with numeric and graphical sight distance analyses. These analyses shall ine/ude the existing topographic features that are proposed to remain after development of the street, as well as any futurefeatures that may be expected or anticipated This condition has been met. This requirement is only valid for crest vertical curves located on a horizontal curve; and where the critical direction of travel is on the inside of the horizontal curve. For the River Heights project the only combination curves that meet this requirement are horizontal curves "A", "B", and "D",(as shown in the PIP drawings). Numerical analysis have been submitted to the City of Springfield that demonstrate that for each of these combination curves the design vertical curve has been designed with a greater available sight-stopping- distance than required for the horizontal curve. Th6 geometric design is sufficient for the very low volume residential streets proposed. This condition is no longer applicable. The LCLGBC deemed that an extra-territorial service extension was not necessary.[BRE EGRI] This condition has been met. The owner has obtained the required Union Pacific license agreement for the installation of the required wastewater pipe. This license was issued on February 7, 2007 by UPRR and requires that the City of Springfield execute the license by signing the agreement and returning to Union Pacific Railroad. A copy of the executed license is included as an attachrnent.(BREEGR2] This condition has been met. The owner has elected to provide public wastewater and storm drain lines along the north boundary of lots 2-12. A 25-foot wide maintenance access has been shown on drawings C12, C13, and C14 of the PIP. PRE.SUBMlTIAl REC'O JUL 3 1 2009 River Heights Final Plat Application Narrative Page 5 of23 . . This condition has been met. All approved public side and rear yard easements will include restrictions that prevent installation of improvements that would impede maintenance access for the public system. Specifically, the CC&R's include language that all fences located across public easements shall include gates to allow access for maintenance vehicles.[BRE EGRJ] The final plat includes reference to private easements and maintenance agreements for all shared private sewer lines.[BRE EGR4] . An 8-inch wastewater pipe is shown on sheet C7 of the PIP, extended to the end ofVitus Lane to provide a future connection to tax lot 60 I. An 8-inch wastewater piPe is shown on sheet CIO of the PIP, extended to provide future service connection to tax lot 802. Public Improvement plans have been prepared consistent with Section 7.03.9 of the City's EDSPM. Specific design considerations for steep hillside development such as flow velocity, energy dissipation, turbulence in manholes and bends, and restraints on pipe movement have been addressed as described below. Section 7.03.9 of the EDPSM states; 7.03.9 Hillside Design Considerations . Sewer design shal! address specific problems and special design considerations for steep hillside development such as velocity, energy dissipation, turbulence in manholes and bends, and restraints on pipe movement. This section of the ESDPM is not specific as to the threshold of when special considerations need to be made, but section 2.02.9 of the ESDPM defines when additional design considerations need to be made for steep wastewater pipe slopes; Section 2.0.2.9 of the EDSPM states; When pipes are laid at steep grades in excess of ten percent, anchor wal! shal! be installed to prevent pipe movements due to forces created by high velocity flows.... ... Where velocities greater than J 5 feet per second are attained, the pipe material shall be ductile iron pipes and special provisions shall be made to protect manholes against erosion and displacement by shock. River Heights Final Plat Application Narrative PRE-SUBMITTAL REC'D JUtpdiet ~P39 . . The ESDPM defines that the design engineer shall incorporate special design considerations when wastewater pipes in excess of 10 percent and velocities in excess of 15 feet per second. Sections of wastewater collection pipes are proposed to be constnicted at slopes greater than 10 percent. However, the peak design flow in no pipe run will exceed 15 feet per second. The design for the wastewater collection pipe system has addressed consideration of steep slopes (greater than 10%) by specifying that the upstream pipe slope shall be carried through the manhole and changes in pipe slope will occur at the outlet edge of the manhole. Additionally, pipe slopes steeper than 10% are shown constructed using the City standard concrete pipe anchor per standard drawing 4-8 with trench drains. Per section 2.02.2.A-l of the EDSPM the peak design wastewater flow rate from the proposed 59 single family homes is 60,000 gallons per day (0.09 cubic feet per second). Using Manning's. equation for open channel flow with n=.009 and a slope of 18 percent the maximum velocity for the project design flow is 7.23 feet per second. All wastewater pipes in the PIP have been designed at less than 18 percent slope and will have velocities of 7.23 feet per second or less. PRE-SUBMITIAL REC'D JUL 3 I 2009 River Heights Final Plat Application Narrative Page 70f23 . . Public Improvement plans have been prepared consistent with Section 7.03.10 of the City's EDSPM. Specific trench drainage measures to handle the flow of water in trench backfill have been incorporated into all trench sections with slopes exceeding 10 percent. The intercepted flow has been directed into an approved storm water facility. The PIP include instructions to the contractor that trench slopes greater than 10% shall include a perforated drain pipe that is connected to the nearest storm drain manhole or pipe. Additionally, City standard detail 4-8 has been modified to act as a water-stop and pipe anchor block. The final plat has been revised to include a public right-of-way extension of River Heights Drive to the adjacent Tax Lot 802 (refer to Condition 2) and a public right of way ofVitus Lane to the eastern boundary of the River Heights subdivision that is generally centered on the common property line between Tax Lots 601 and 600 (refer to Condition 3). Public Improvements within these right-of-ways include storm sewer lines to the subdivision boundary. Please note, that consistent with staff-clarification of Condition 15, the River Heights storm drainage and detention system has been designed to accommodate pre-development flows from adjacent parcels ofland that have ordinarily flowed onto the River Heights project. This condition will be met when the City of Springfield provides an agreement to be signed by the owner. Agreements between the Developer (Owner of Tract A) and the City of Springfield and between the Developer and Willanlalane Parks and Recreation District (attached) have been completed to provide for the maintenance requirements of Tract A. PRE-SUBMITTAL REC'D JUL 3 I 2009 River Heights Final Plat Application Narrative Page 8 of23 . . The Stormwater system for this subdivision including the detention ponds have been sized to accommodate 3,500 square feet of impervious surface from each proposed lot as well as pre- development flows from off-site parcels (specifically including Tax Lots 600 and 801). It must be noted that all adjacent parcels are downhill from the River Heights project and historically have not had any defined stormwater runoff flows directed at the project property. The Stormwater system has been designed to include separate storm sewer laterals to lots 45 and 46, consistent with Section 7.04.2 of the City's EDSPM. . Lots # 1-# 12 have been provided a back of lot public stormwater consistent with the requirements of Public Works during the PIP approval. Lots #19-#21 and #22-#27 were required by COA #24 to have a back of lot private storm drain pIpe. A typical detail drawing showing an "individual piped dispersion system" for rooftop runoff for lots 30-35 is attached.[BRE EGR6] This condition is no longer applicable. The roof runoff from the proposed lots 1-12 will be collected in a public stormwater pipe located along the north property line. A recorded joint use access and maintenance agreement has been placed on all private, shared stormwaterlines and the lots they serve. (Lots #24-#31 and Lots #12-#13 and #15#16[BRE EGRJ] Maintenance access consistent with the requirements of Section 4.12 of the City's EDSPM to the detention ponds has been provided via a perimeter access road as shown on sheet C16 and CI 7 of the Public Improvement Plans. PRE-SUBMITTAL REC'D JUL 3 1 2009 River Heights Final Plat Application Narrative Page 9 of23 . . The design for the storm drain collection pipe system has addressed consideration of steep slopes (greater than 10%) by specifYing that the upstream pipe slope shall be carried through the manhole and changes in pipe slope will occur at the outlet edge of the manhole. Additionally, pipe slopes steeper than 10% are shown constructed using the City standard concrete pipe anchor .per standard drawing 4-8 with trench drains. Public Improvement plans have been prepared consistent with Section 4.04.D of the City's EDSPM, which states; 4.04.D Pipe Size 1. Pipe from an inlet to the main line in the public system shall be a minimum often-inch in diameter. 2. Main line pipe shall be a minimum of I2-inch in diameter. 3. Service laterals for single family residences hall be six inch diameter. All other service laterals shall be a minimum of IO-inch diameter. The Public Improvement Plans have been developed with the minimum inlet to main line pipe size of 10-inches, a minimum mainline pipe size of 12-inches, and a 6-inch service lateral to each proposed single family lot. Consistent with Section 4.04.EI of the EDSPM all storm pipes have been designed to achieve a minimum velocity of three feet per second at 0.5 part full based upon Table 4-1 and the associated "n" value. Table 4-1 prescribes a Manning's "n" value of 0.013 for PYC pipes. Below is the table based on Manning's equation for open channel hydraulics demonstrating the minimum slope for nominal pipe diameters to meet the requirements of 4.04.EI; PIPE FLOW Manning's MIN SIZE DEPTH n-value SLOPE inches inches n ft/ft 6 3 0.13 0.0111 8 4 0.13 0.0075 10 5 0.13 0.0056 12 6 0.13 0.0044 15 7.5 0.13 0.0032 18 9 0.13 0.0025 21 10.5 0.13 0.0021 24 12 0.13 0.0018 PRE.SUBMITTAl REC'D JUL 3 1 2009 River Heights Final Plat Application Narrative Page 10 of23 . . Section 4.04.E2 requires analysis of pipes that exceed critical flow velocities for hydraulic jumps and the effect on down stream water levels at peak flow. The critical manholes for analysis are those that are at points where the mainline storm drain pipe is changing from supercritical to subcritical flow. This change in flow regime condition can result in a hydraulic jump. Critical manholes are MH3, MH2, MH28, and MH35. The table below shows that at these manholes the difference in elevation from the energy grade line to the structUre rim exceeds I-foot for the 25- year storm event. If a hydraulic jump were to occur in the manhole the height would be less than the energy grade line.

Public Improvement plans have been prepared consistent with Section 7.03.10 of the City's EDSPM. Specific trench drainage measures to handle the flow of water in trench backfill have been incorporated into all trench sections with slopes exceeding 10 percent. The intercepted flow has been directed into an approved storm water facility. The PIP include instructions to the contractor that trench slopes greater than 10% shall include a perforated drain pipe that is connected to the nearest storm drain manhole. Additionally, City standard detail 4-8 has been modified to act as a water-stop and pipe anchor block Public Improvement plans have been prepared consistent with Section 7.04.10 of the City's EDSPM. The standard drawings for development of hillside areas recommended in Appendix A in the Hillside Pavement Distress Study, 1994, by Dames and Moore have been incorporated into the Public Improvement plans refer to Sheets G3 and G4.

Storm drainage from Lots 24 through 31 has been provided via a privately owned, privately maintained piped stormwater line on property serving lots 24-31. Designs for this piped system may be viewed on Sheets C 18 and C 19 of the Public Improvement Plans. Public Improvement plans have been prepared that incorporate the groundwater control requirements of Section 7.06 of the City's EDSPM into the design. Because the staff report did not reference specific sub-sections of Section 7.06 to address, the Applicant has addressed all sub-sections of Section 7.06 of the EDSPM herein. Section 7.06 of the EDSPM states: 7.06.1 Embankment Restrictions Construction of embankments shall not be allowed on top of soils with a plastic index greater than 30. Plans for embankments shall show construction details for maintaining drainage to eliminate shrink/swell problems evident in adjacent developments. Laboratory testing of the native material demonstrated that the PI values were less than 30. 7.06.2 Persistent Flow Conditions All persistent flow conditions, except for any identified open water component of the conceptual storm water plan, shall be directed into the piped storm system. Preliminary work has not identified any persistent flow conditions. The Public Improvement Plans contain construction notes 'on Sheets 03 and 04 directing the contractor to direct any persistent flows encountered during construction to the public stormwater system. 7.06.3 Longitudinal Drainage Systems The developer shall include longitudinal drainage systems along the uphill side of all streets constructed on cut slopes for each phase of the development. These drains shall discharge to a piped drainage facility, not the street gutter. The Public Improvement Plans contain the standard drawings for hillside development as recommended by the Dames and Moore "Hillside Pavement Distress Study" and as required by Condition 23. These drawings are for standard "french drain" and seepage blankets. Sheets 03 and 04 of the Public Improvement Plans direct the contractor to construct these features on the uphill side of all street cuts and to hard pipe the drains to the public storm water system. 7.06.4 Interception of Springs and Watercourses Saturation of the street subgrade and of building pads shall be prevented Therefore, the project storm drainage system shall be designed to intercept and remove from the street structural section and street subgrade the flows from all known springs and watercourses. In addition, the flow from all springs and watercourses encountered during street and utility construction' and lot pad grading 'shall be intercepted and removed with discharge into the project storm drain system.

The Tentative Subdivision Decision was issued on May 2, 2006 and incorporated the conditions and requirements of the Hillside Development and Tree Felling Permits. As stated on page 33 of the . Tentative Subdivision Decision, the approval was valid for 2-years. This approval is scheduled to expire on May 2, 2008. From the date of the decision the applicant, and their agents, have been working on the required conditions of approval. Due to the complexity of the project the Public Improvement Permit construction documents were approved by Public Works on March 6, 2008. At this time the applicant, contractor and EGR are working at gathering the remaining documentation to have PIP Agreement executed by the City and construction will begin in the next few weeks. Additional work items have come up during the refinement of the development. Specifically, Breeden is in the process of having a Serial Property Line Adjustment completed with Rainbow Water District. This application was determined to be mutually beneficial during the concurrence process for the development. It is preferable to have the SPLA nearer to completion prior to submitting a Final Plat application for the subdivision. The design tearn has been working in good faith with City staff to complete all of the conditions for this project and we expect to have a final plat application submitted this summer.

The Owner has directed EGR to submit Land Drainage and Alteration Permit . (LDAP) amendments to address grading oflot areas where suitable. For this project the underlying land use decisions (SOO2006-00006, Tree Felling DRC2006-00006 and Hillside Development DRC2006-00005) greatly limit the areas available for lot grading and fill during the public street and utility installations. Specifically, only lot areas that are downhill of the public street, that do not contain significant trees or other vegetation, and are generally free of conservation or preservation areas are candidates for lot fill at this time. With these constraints only three lot fill areas were identified as suitable; lots #24-26, lots #20-#25, and lots #35-#39. LDAP Amendment #2 showing grading activities on lots #24-#26 has been approved by the City of Springfield. EGR has submitted LDAP Amendment #3 shows potential fill on lots #35 to #38 and LDAP Amendment #4 shows potential fill on lots #20-#23. The purpose of this memorandum of is to provide a narrative describing proposed lot grading during the public improvement construction on the River Heights Subdivision project. This memorandum will document how LDAP Amendments #2, #3, and #4 meet the requirements of the underlying Hillside Development and Tree Felling land use approvals. LDAP Amendments Consistency with Tree Fellin!! Permit The River Heights project was issued a tree felling permit (DRC2006-00006) that included staff findings and conditions of approval. LDAP Amendments #2, #3, and #4 have included the collection of data showing trees greater than 5" dbh as part of the preparation of the site Plmp~E~BMfffAL REC'D JUL 3 1 2009 . . Memorandum Page 2 of 6 surveys were perfonned in the last month as a confirmation to the original site survey conducted in 2004. The submitted LDAP amendment site plans identify trees not shown on the original site survey. This inconsistency can be attributed to two factors; in the time between the original site survey and now, trees that were smaller than 5" 'dbh have grown and significant invasive understory (blackberries) have been removed during the course of developing the project. allow access to additional trees. LDAP Amendments Tree Impacts Summary LDAP Amendment #2, #3, and #4 will remove a total of22 trees greater than 5" in dbh. LDAP Amendment #2 removed three (3) trees greater than 5" dbh from Lot #25 and two (2)trees greater than 5" dbh froin Lot #26. These trees removed are outside of the identified building envelope areas but are within the grading areas. LDAP Amendment #3 proposes removing four (4) trees greater than 5" dbh from Lot #35. Threeof these trees will have critical roots zones that are located in the public street cut bank. LDAP Amendment #4 proposes removing eight (8) trees greater than 5" dbh from the building envelope and three (3) trees outside of the building envelope on Lot #22. This plan also proposes removing two (2) trees greater than 5" dbh from the building envelope of Lot #23. Table 1 LDAP Amendment Tree Removal Summary Removed from Building Removed Outside Building Amendment # Envelop Envelope Total Removed #2 0 5 5 #3 0 4 4 #4 10 3 13 None of the trees to be removed are located in Conservation or Preservation areas identified during the tentative subdivision, tree felling, or hillside development applications and approvals. Consistency with Tree Felling Permit Findings " The Tree Felling Permit issued for the River Heights project included an in depth analysis from staff on how the proposed project was consistent with the Springfield Development Code Article 38 (SDC 38). As shown in the analysis below, the LDAP Amendment tree felling is conSistent with the staff analysis and conditions of approval. In reference to SDC 38.040(1) staff provided the flowing findings; 1. The applicant proposes to remove approximately 355 trees for the construction of public improvements; the applicant will protect approximately 1045 trees to remain after construction and re-plant approximately 280 trees. Another 450 trees will be left to the discretion o!.future owners of residential lots. Trees to be felled during the LDAP amendment activities are in the discretionary grouping described above. The Owner, Breeden Bros., Inc, will be developing and building single family residential homes and has made the detennination that removal of the trees outside of the building envelope areas 2535B Pre;ne Road, Eugene, Oregon 97402' Phone (541) 688-8322. Fax (541) 688-8087 PRE.SUBMITTAL RECID JUL 3 1 2009 . . Memorandum Page 3 016 to allow lot grading results in a better final product. Over the course of the project, the Owner has elected to leave trees standing as long as practical. 2. Construction requiredfor the development of building envelopes, streets and utilities within the subdivision warrants the removal of vegetation within these areas (See grading and landscape preservation and removal plans submitted). Tree felling within these areas may occur during the PIP process after surveying of proposed cuts and fills and placement of protective fencing around all areas to be protected during construction No trees are to be felled due to poor health during the construction process. The LDAP amendments are a refinement of the tentative subdivision grading plan. Significant volume of material excavated from the street and utility construction has been determined to be suitable for lot fill. Tree to be protected will be marked with orange fencing prior to grading activities. . The proposed LDAP amendments will result in approximately a total of 17,000 cubic yard of excavated material staying onsite. Placement of this material onsite will eliminate over 2,000 truck trips leaving the site and reduce the construction traffic past adjoining properties. 3. Trees outside of public improvement areas, utility easements, building envelopes and protective easements are left to the discretion a/fUture owners and may be removed Hazard trees within Conservation Easements can and should be removed and replaced in accordance with proposed easement language. Removal of 5 or more trees with a 5 inch or larger diameter requires an independent tree felling permit for each lot. Breeden Bros. Inc. (Owner) will be the developer and builder of the future single family homes on the impacted lots. Less than 5 trees are being removed from outside of the identified building envelopes and will not require an individual tree felling permit for each lot. In reference to SDC 38.040(3) staff provided the flowing [mdings; 1. The trees proposedfor removal are limited to those necessary to install subdivision improvements. Removal of trees for the LDAP amendment areas is consistent with this fmding because they are being removed to allow for lot development. 2. Trees within approved building envelopes may be removed at the time of subdivision development. Removal of more than 5 trees with a dbh of 5 inches or greater located outside building envelopes and easements will require a separate tree felling permit pursuant to SDC, Article 38. Removal of trees in the LDAP amendment areas is consistent with this fmding because as described above, the LDAP amendments do not propose removinK more than 5 trees from outside of a building envelope on any single lot. 3. The standard is met subject to an approved deveiopment plan (i.e. public improvement plan for the qffected areas). Removal of trees in the LDAP amendment areas is consistent with this finding because a refmement plan (LDAP Amendment) has been submitted for approval. Consistencv with Tree Felling Conditions of Approval The River Heights project was issued a tree felling permit (DRC2006-00006) that included staff fmdings and conditions of approval. This decision included four conditions of approval that are reproduced below. Condition 1: All public rights of way, easement areas and building envelopes shall be field surveyed and staked prior to removal of trees allowed in accordance with this decision All trees to be protected shall be 25358 Prairie Road' Eugene, Oregon 97402.

The landscape architect shall inspect all. protective easement areas after construction activities to verifY the health of all trees along the common boundary between construction and protected areas. Any tree compromised by construction shall be removed and a replacement tree shall be planted in accordance with the planting methods described in the adopted Vegetation and Re-vegetation Plan The submitted LDAP Amendments comply with this condition of approval. Shown on the submitted site plans are all recently surveyed trees and the building envelope areas. Trees located inside of the building envelopes can be removed in accordance with the issued tree felling permit. Prior to grading activity, LDAP Staff will inspect the liIDits of activity and confirm that trees identified to remain are . marked with orange construction fencing. Condition 2: Notice of Intent to proceed shall be provided to the City and residents of abutting properties along the north boundary of the subject site (Ambleside) 5 days prior to the commencement of tree removal work This condition of approval is not applicable to the LDAP Amendments as the work is not adjacent to the north property line. Prior to right-of-way tree removal notice was sent to the adjacent developments. Condition 3: Prior to tree removal. the applicant's landscape architect and aforestry consultant shall provide a written assessment of the risk of wind throw to the stands of timber to remain on the subject site, including preservation easement and residential construction areas abutting the R WD property. The wind throw assessment shall be completed prior to removal and incorporated into a Revised Vegetation and Re-vegetation Report along with any measures taken to reduce wind throw risks prior to Final Plat Approval. This condition of approval is not applicable to the LDAP Amendments because no significant stands of trees are present in the areas to be graded. Condition 4: The Vegetation and Revegetation Report and CCRs shall be revised to prohibit fencing within Preservation Easements and limit the use of fencing within Conservation Easements. Fences within or around tree conservation easements shall be placed to avoid root damage. be non-site obscuring and be constructed, coated or painted black to blend with existing vegetation Fences shall not extend south of the h'ee conservation easement at north property line across utility easements. Fences along the north property line shall be in accordance with the fencing standards of SDC Article 16. The applicable portions of the tree preservation easements shall be included in deed restrictions and CeRE subject to reviel1l and approval by the City of Springfield . This condition of approval is not applicable to the LDAP Amendments and is project specific. This condition will be addressed at the time of final plat processing. Consistency with Tree Felling Conclusion All trees to be removed during the LDAP Amendment work is the minimum to allow for lots fill to be placed in project acceptable areas. This tree removal is consistent with the issued tree felling permit because the removal will be either from the building envelopes and no more than 5 trees from outside of the envelope for any individual lot. The proposed LDAP amendments will result in approximately a total of 17,000 cubic yard of excavated material staying onsite. Placement of this material onsite will eliminate over 2,000 truck trips leaving the site and reduce the construction traffic past adjoining properties. PlUUBMlIIAl REC'D 25356 Prairie Road' Eugene.

The LDAP Amendments are consistent with SDC 26.070 Reports Required as described in the following analysis. SDC 26.070(1) SDC 26.070(1) requires that a soils and geology report be prepared for the site that includes reconunendations for grading and development of the project. GeoScience Inc., has prepared geologic reports that included design reconunendations in July of 200S, July of 2006, and August of 2007. Additionally, GeoScience has continued to be involved during street and utility construction to observe and provide reconunendations. These observations have determined that material excavated from areas of the streets and utilities is suitable for lot fill. As described in EGR's July 14, 2008 memorandum, GeoScience will observe, report and provide a final certification or reconunendations for all lot fill placed. The LDAP Amendments have been prepared in accordance with GeoScience's' reconunendations. SDC 26.070(2) SDC 26.070(2) requires a grading plan report that include existing and proposed grades, details of the terrain and area drainage, location of existing structures, direction of drainage flow and approximate grade of streets, and finished contours to be achieved by grading. The LDAP amendment site plans prepared by EGR & Associates include all of the required information and are a refinement of the grading plan submitted with the tentative subdivision. Specifically, these site plans show the lot area, future building envelopes, S:'[oot interval existing and proposed contours, significant vegetation, and erosion control requirements. The proposed grading activities will not alter the surface water drainage patterns and are consistent with the stormwater management plan prepared for the development. LDAP Amendments Hillside Development Conclusion Submitted LDAP amendments are a refinement of the original subdivision and hillside development approvals. The Owner and EGR have developed the LDAP amendments for consistency with the underlying land use approvals and balancing the goals of the project.

Memorandum Page 6 016 Summary The submitted LDAP amendments will result in approximately 17,000 cubic yards of material excavated from the public streets and utility construction to be safely placed on private lot areas. Grading work will be consistent with the project geology reports and GeoScience will be providing onsite recommendations, observations, reporting and final certifications or recommendations. EGR has prepared the submitted LDAP amendments to be consistent with the underlying land use approvals. The submitted amendments are a refinement of the conditionally approved tentative grading plans. Twenty-two trees will be removed from outside of the public street and utility construction. As demonstrated above, not more than five trees will be removed from outside of a building envelope on any single lot. The proposed grading activities will not alter the surface water drainage patterns as documented in the approved stormwater management plans. All disturbed areas will be stabilized by the methods and schedule established for the LDAP.

Public street excavations for the River Heights Subdivision (P30520) are producing sizeable volumes of excavated material that has been deemed suitable for lot fill by the project Engineering Geologist (GeoScience, Inc.). The Owner has directed EGR to submit Land Drainage and Alteration Pennit (LDAP) amendments to address grading ofJot areas where suitable. For this project the underlying land use decisions (SUB2006-00006, Tree Felling DRC2006-00006 and Hillside Development DRC2006-00005) greatly limit the areas available for lot grading and fill during the public street and utility installations. Specifically, only lot areas that are downhill of the public street, do not contain significant trees or other vegetation, and are generally free of conservation or preservation areas are candidates for lot fill at this time. With these constraints only three lot fill areas were identified as suitable; lots #24-26, lots #20-4125, and lots #35-#39. LDAP Amendment #2 showing grading activities on lots #24-#26 has been submitted and is being reviewed by the City of Springfield. EGR will be submitting two additional LDAP aniendments to address the lot areas identified above concurrently with this memorandum. Procedures for Lot FiU The project Engineer (EGR & Associates) will be responsible for the production of grading plans for inclusion into the LDAP amendments. These grading plans will be developed consistent with the underlying land use decisions and project requirements. . The Project Engineer will submit the PRE-SUBMITTAL REe'D JUL 3 1 2009 . . Memorandum Page 2 012 proposed LDAP Amendments for approval by the City. When approved, the Project Engineer will coordinate the installation ofESC BMP's, LDAP Staff Inspections, and project Engineering Geologist observations and reporting. The project Engineering Geologist (GeoScience, Inc.) has been retained by the owner to provide onsite recommendations, inspections, and reporting of fill to be placed in building pad areas and on private lots. Onsite observations and construction reporting will include determination of suitable material, observation of fill placement, and a fmal report documenting the construction activities. Certification of Lot Fill The project Engineering Geologist will provide a fmal report for the placement of fill in all approved lot fill areas. This certification report will include recommendations for future structure foundation requirements. At this time, it is anticipated that not all lot fills will be suitable for "standard" spread- footing construction. The fmal report will detail the recommendations and requirements for these lots. Hillside Develooment Reoort As required by DRC2006-00005 a final Hillside Development Report is required prior to final plat approval. Included in the final Hillside Development Report are individual lot notification sheets, fmal geotechnical recommendations, final vegetation re-vegetation requirements, and the project CC&R's. It is the Owners intent that the Final Hillside Development Plan and/or CC&R's will require that, prior to foundation construction, every lot have a site specific geological investigation and report with foundation recommendations. For lot areas that included grading activities allowed under an LDAP amendment during the street construction, the Owner and/or Project Engineer will coordinate and make sure that the individual lot figures include notification that fill was placed during the street construction and summarize the geotechnical recommendations or requirements for these lots.

The Owner has directed EGR to submit Land Drainage and Alteration Permit (LDAP) amendments to address grading of/ot areas where suitable. For this project the underlying land use decisions (SUB2006-00006, Tree Felling DRC2006-00006 and Hillside Development DRC2006-00005) greatly liniit the areas available for lot grading and fill during the public street and utility installations. Specifically, only lot areas that are downhill of the public street, that do not contain significant trees or other vegetation, and are generally free of conservation or preservation areas are candidates for lot fill at this time. With these constraints only three lot fIll areas were identified as suitable; lots #24-26, lots #20-#25, and lots #35-#39. LDAP Amendment #2 showing grading activities on lots #24-#26 has been approved by the City of Springfield. EGR has submitted LDAP Amendment #3 shows potential fill on lots #35 to #38 and LDAP Amendment #4 shows potential fill on lots #20-#23. The purpose of this memorandum of is to provide a narrative describing proposed lot grading during the public improvement construction on the River Heights Subdivision project. This memorandum will document how LDAP Amendments #2, #3, and #4 meet the requirements of the underlying Hillside Development and Tree Felling land use approvals. LDAP Amendments Consistency with Tree Felling' Permit The River Heights project was issued a tree felling permit (DRC2006-00006) that included staff findings and conditions of approval. LDAP Amendments #2, #3, and #4 have included the collection of data showing trees greater than 5" dbh as part of the preparation of the site plans. These tree PRE.SUBMITTAL REC'D JUL 3 1 2009 . . Memorandum Page 2 of6 surveys were performed in the last month as a confirmation to the original site survey conducted in 2004. The submitted LDAP amendment site plans identify trees not shown on the original site survey. This inconsistency can be attributed to two factors; in the time between the original site survey and now, trees that were" smaller than 5" dbh have grown and significant invasive understory (blackberries) have been removed during the course of developing the project allow access to additional trees. LDAP Amendments Tree Impacts Summary LDAP Amendment #2, #3, and #4 will remove a total of22 trees greater than 5" in dbh. LDAP Amendment #2 removed three (3) trees greater than 5" dbh from Lot #25 and two (2)trees greater than 5" dbh from Lot #26. These trees removed are outside of the identified building envelope areas but are within the grading areas. LDAP Arllendment #3 proposes removing four (4) trees greater than 5" dbh from Lot #35. Three of these trees will have critical roots zones that are located in the public street cut bank. LDAP Amendment #4 proposes removing eight (8) trees greater than 5" dbh from the building envelope and three (3) trees outside of the building envelope on Lot #22. This plan also proposes removing two (2) trees greater than 5" dbh from the building envelope of Lot #23.

Consistency with Tree Fellin!! Permit Findin!!s The Tree Felling Permit issued for the River Heights project included an in depth analysis from staff on how the proposed project was consistent with the" Springfield Development Code Article 38 (SDC 38). As shown in the analysis below, the LDAP Amendment tree felling is consistent with the staff analysis and conditions of approval. In reference to SDC 38.040(1) staff provided the flowing findings; 1. The applicant proposes to remove approximately 355 trees for the construction of public improvements; the applicant will protect approximately 1045 trees to remain iIjler construction and re-plant approximately 280 trees. Anather 450 trees will be left to the discretion offuture owners of residentiallols. Trees to be felled during the LDAP amendment activities are in the discretionary grouping described above. The Owner, Breeden Bros., Inc, wilL be developing and building single family residential homes and has made the determination that removal of the trees outside of the building envelope areas 2535B Prairie Road, Eugene.

Significant volume of material excavated from the street and utility construction has been determined to be suitable for lot fill. Tree to be protected will be marked with orange fendng prior to grading activities. The proposed LDAP amendments will result in approximately a total of 17,000 cubic yard of excavated material staying onsite. Placement of this material onsite will eliminate over 2,000 truck trips leaving the site and reduce the construction traffic past adjoining properties. 3.

(Owner) will be the developer and builder of the future single family homes on the impacted lots. Less than 5 trees are being removed from outside of the identified building envelopes and will not require an individUal tree felling permit for each lot. In reference to SDC 38.040(3) staff provided the flowing fmdings; 1. The trees proposedJor removal are limiled to those necessary 10 ins/all subdivision improvements. Removal of trees for the LDAP amendment areas is consistent with this finding because they. are being removed to allow for lot development. 2.

Removal oj more Ihan 5 trees with a dbh oJ5 inches or greOler localed outside building envelopes and easements will require a separOle tree Jelling permit pursuanllO SDC, Arlicle 38. Removal of trees in the LDAP amendment areas is consistent with this fmding becaUse as described above, the LDAP amendments do not propose removing more than 5 trees froln outside of a building envelope on any single lot. 3. The slondard is met subjecllo on approved developmenl plan (i.e. public improvement planJor Ihe affecled areas). Removal of trees in the LDAP amendment areas is consistent with this finding because a refinement plan (LDAP Amendment) has been submitted for approval. Consistency with Tree Felling Conditions of Approval The River Heights project was issued a tree felling permit (DRC2006-00006) that included staff fmdings and conditions of approval, This decision included four conditions of approval that are reproduced below. Condition I: All public rights oj way, easement areas and building envelopes shall be field surveyed and Slaked prior 10 removal oj trees allowed in accordance with this decision. All trees /0 be protected shall be 25356 Prairie Road' Eugene, Oregon 97402' Phone (541) 688-8322' Fax (541) 688-8087 PRE-SUBMITTAL REC'D JUL 3 1 2009 . . Memorandum Page 4 016 fenced with orange construction barrier to protect root zones. The landscape architect shall inspect all protective easement areas (l/ier construction activities to verify the health of all trees along the common boundary between construction and protected areas. Any tree compromised by construction shall be removed and a replacement tree shall be planted in accordance with the planting methods described in the adopted Vegetation and Re-vegetation Plan. . The submitted LDAP Amendments comply with this condition of approval. Shown on the submitted site plans are all recently surveyed trees and the building envelope areas. Trees located inside of the building envelopes can be removed in accordance with the issued tree felling permit. Prior to grading activity, LDAP Staff will inspect the limits of activity and confirm that trees identified to remain are marked with orange construction fencing. Condition 2: Notice of Intent to proceed shall be provided to the City and residents of abutting properties along the north boundary of the subject site (Ambleside)" 5 days prior to the commencement of tree removal work This condition of approval is not applicable to the LDAP Amendments as the work is not adjacent to the north property line. Prior to right-of-way tree removal notice was sent to the adjacent developments. Condition 3: Prior to tree removal, the applicant's landscape architect and aforestry consultant shall provide a written assessment of the risk of wind throw to the stands of timber to remain on the subject site, including preservation easement and residential construction areas abutting the RWD property. The wind throw assessment shall be completed prior to removal and incorporated into a Revised Vegetation and Re-vegetalion Report along with any measures taken to reduce wind throw risks prior to Final Plat Approval. This condition of approval is not applicable to the LDAP Amendments because no significant stands of trees are present in the areas to be graded. Condition 4: The Vegetation and Revegetation Report and CCRs shall be revised to prohibit fencing within Preservation Easements and litnit the use of fencing within Conservation Easements. Fences within or around tree conservation easements shall "be placed to avoid root damage, be non-site obscuring and be constructed, coated or painted black to blend with existing vegetation. Fences shall not extend sOUlh of the tree conservation easement at north property line across utility easements. Fences along the north property line shall be in accordance with the fencing standards of SDC Article 16. The applicable portions of the tree preservation easements shall be included in deed restrictions and CCRs subject to review and approval by the City of Springfield This condition of approval is not applicable to the LDAP Amendments and is project specific. This condition will be addressed at the time of final plat processing. Consistency with Tree Felling Conclusion All trees to be removed during the LDAP Amendment work is the minimum to allow for lots fill to be placed in project acceptable areas. This tree removal is consistent with the issued tree felling permit because the removal will be either from the building envelopes and no more than 5 trees from outside of the envelope for any individual lot. The proposed LDAP amendments will result in approximately a total of 17,000 cu~ic yard of excavated material staying onsite. Placement of this material onsite will eliminate over 2,000 truck trips leaving the site and reduce the construction traffic past adjoining properties. 25358 Prairie Road. Eugene, Oregon 97402.

Page 5 016 LDAP Amendments Consistency with Hillside Development Approval The River Heights project included a Hillside Development approval because portions of the site are located above the 670 foot elevation mark and include slopes exceeding 15%. The proposed LDAP Amendments were developed to be consistent with the underlying Hillside Development approval. Springfield Development Code Article 26 provides the requirements for Hillside Development The City of Springfield issued a decision with s~ analysis for the Hillside decision (DRC2006-00005). Section 26.050 Development Density Options, 26.060 Street Grade Standards, and 26.090 Fire Protection Standards are not applicable to the LDAP Amendments. The LDAP Amendments are consistent with SDC 26.070 Reports Required as described in the following analysis. SDC 26.070(1) SDC 26.070(1) requires that a soils and geology report be prepared for the site that includes recommendations for grading and development of the project. GeoScience Inc., has prepared geologic reports that included design recommendations in July of 2005, July of 2006, and August of 2007. Additionally, GeoScience has continued to be involved during street and utility construction to observe and provide recommendations. These observations have determined that material excavated from areas of the streets and utilities is suitable for lot fill. As described in EGR's July 14, 2008 memorandum, GeoScience will observe, report and provide. a final certification or recommendations for all lot fill placed. The LDAP Amendments have been prepared in accordance with GeoScience's recommendations. SDC 26.070(2) SDC 26.070(2) requires a grading plan report that include existing and proposed grades, details of the terrain and area drainage, location of existing structures, direction of drainage flow and approximate grade of streets, and finished contours to be achieved by grading. The LDAP amendment site plans prepared by EGR & Associates include all of the required information and are a refinement of the grading plan submitted with the tentative subdivision. Specifically, these site plans show the lot area, future building envelopes, 5-fo'ot interval existing and proposed contours, significant vegetation, and erosion control requirements. The proposed grading activities will not alter the surface water drainage patterns and are consistent with the stormwater management plan prepared for the development. LDAP Amendments Hillside Development Conclusion Submitted LDAP amendments are a refinement of the original subdivision and hillside development approvals. The Owner and EGR have developed the LDAPamendments for consistency with the underlying land use approvals and balancing the goals of the project. 25358 Prairie Road, Eugene, Oregon 97402.
