WRITTEN STATEMENT
FOR THE
JASPER MEADOWS PHASE 10
TENTATIVE SUBDIVISION ApPLICATION
This application is a proposal to subdivide the property identified as Phase lOin the
Jasper Meadows Master Plan (Tax Map 18-02-03-33, portion of Tax Lot 100) into 21 lots.
Currently, the site is vacant with wetlands consuming much of the north'ern portion. Two public
street rights-of-way are proposed for dedication to the city. In addition, Ian emergency vehicle
access road is proposed to extend from the cul-de-sac to Bob Straub Parkway with a locked gate
,
at both ends. This access road will be paved from the cul-de-sac to the driveway for Lot 10; the
surfacing type from the driveway to Bob Straub Parkway has not been determined yet, but will
meet or exceed the Fire Department requirement for 80,000-pound load!
The tract containing the wetlands is to be dedicated to Willamalke concurrent with the
plat. At the time of platting, we will coordinate with Willamalane regaiding the dedication
method (on the face ofthe plat or by separate document). The boundari1es ofthe residential
development are laid out to not encroach on the delineated wetlands. I
Construction of the streets and utilities will require some earthwork and tree removal.
,
The full extent ofthese tasks will be determined with the construction plans. With the exception
of utility extensions along the east side of the street, no earthwork will dccur and no trees will be
removed within the wetlands. Connections to facilities in the prior phaJe that were not extended
to the phase boundary are the only off-site improvements. The streets, btilities and lots are laid
out to match the site contours as well as possible to minimize the earthJ,ork. It is acknowledged
that tall retaining walls along the south and north boundaries ofthe residential lots will be
required. Based on the developer's experience and an approximate cost-benefit analysis, it was
determined that this layout created lots that are more saleable and cost ~fficient than alternative
designs (such as terracing). Please note that the locations and dimensiohs of the public
improvements, especially utilities, are intended to be approximate. A dbtailed design will be
performed prior to submittal of the Public Improvement Plans. In addition, the street trees
shown are solely for the purpose of acknowledging that they will need to be planted. Their
actual location will be determined at the time they are installed.
The Lane County Soil Survey shows the site as having Hazelair silty clay loam, 2 to 7
percent slopes (528) across the wetland portion of the site and Salkum silt loam, 2 to 6 percent
,
slopes (1208) across the portion of the site to be developed. The Soil Survey indicates that the
seasonal high water table for the Salkum soil is more than 6 feet belowl'the ground surface. The
Survey also indicates there may be problems with low soil strength and slow drainage in the
Salkum soil. However since it provides solutions that are in-line with dtandard construction
practices, no Geotechnical Report was obtained. . I
A review of the Conditions of Approval for the Master Plan (Case Number LRP2004-
00014) did not reveal any conditions that need to be specifically addres'sed by this application.
We have not yet been provided with information on the Master Plan Arhendment Conditions of
Approval so cannot address compliance with that planning action. I
This subdivision qualifies as a cluster subdivision to accommodate the large wetland
tract. Adjustment to specific dimensional standards is not requested, bbt the lot layout in the area
of the cul-de-sac is somewhat unique. Specific house plans have not y6t been selected for the

.
lots; at the time of home construction, the developer will ensure that they meet the Neighborhood
Compatibility and Specific Development Standards in SDC 3.2-230F&G.
This phase will have a Homeowner's Association structured likelthe prior phases. The
Homeowner's Association will be responsible for maintenance of the shared, non-public
storm water facilities. A draft ofthe agreement will be prepared for city Ireview at the time of
plattingT. h' . d . dd" I I' I" I h" I'

acknowledged that a Tree Felling Permit and a Land and Drainage Altefation Permit will be
required prior to the removal of trees or grading; however, these applications are being deferred
to submittal at the time the permits are needed.

RESTRICTION STATEMENT
FOR THE TENTATIVE SUBDIVISION ApPLICATION
I
The title report issued by Cascade Title Company on December 8, 20 I 0 lists eight
restrictions as applicable to the lands in this subdivision. The following! is a discussion of each
ofthese restrictions:
2. Easement, including the terms and provisions thereof, granted MouI)tain State Power
Company, by instrument recorded September 19, 1945, in Book 2971, Page 285, Lane County
Oregon Deed Records.
This document is like the vast majority of other local Mountain State Power easements; it
does not disclose a location. In conformance with standard local p1actice, this easement will
be noted on the subdivision plat, but not viewed as restricting constrction on the lots.
3. Easement, including the terms and provisions thereof, granted Moul).tain States Power
Company, by instrument recorded September ]8, 1947, in Book 343, Page 615, Lane County
Oregon Deed Records. I
This document is like the vast majority of other local Mountain State Power easements; it
does not disclose a location. In conformance with standard local piactice, this easement will
be noted on the subdivision plat, but not viewed as restricting construction on the lots.
4. Easement agreement, including the terms and provisions thereof, b~tween Joseph D. Bando
and J.D. Bando Corporation, and Gordon W. Tripp, recorded Septebber 4, ] 98], Reel No.
1155, Reception No. 8138188, Lane County Official Records. I
This document creates a drainage ditch easement across the northern portion of the west line
of the parent parcel to this subdivision. The easement does not exte1nd south to this
subdivision.
5. Easements, notes and restrictions shown, set forth or delineated on the recorded partition plat.
A review of the partition plat shows that no easements or restrictio~s beyond those listed
above existed at the time of partitioning. It was noted that the first kasement listed in the
partition notes (upper left corner of the plat) gives an odd merging bfthe date and recording
information from Exceptions #2 and 3 discussed above. This was rhiewed with the title
company and determined to be an error on the plat.
6. Resolution Initiating Annexation, including the terms and provisions thereof, by the City of
Springfield and recorded September 23, 2003, Reception No. 20031093155, Lane County
Deeds & Records and Annexation Agreement, including the terms and provisions thereof,
recorded October 06,2003, Reception No. 2003-097367, Lane Couhty Deeds and Records.
It is our understanding that the Approved Master Plan was prepar~d to conform to the
requirements of these documents. Because this subdivision applicdtion conforms to the
Approved Master Plan as amended by the City of Springfield, a dethiled analysis of
compliance with these documents is not seen as necessary and was Inot prepared.

7. Agreement for Construction of Public Improvements (Jasper Road Extension) and for
Dedication of Right of Way to Lane County, including the terms and provisions thereof,
,
recorded June 25, 2004, Reception No. 2004-048548, Lane County <Dregon Deeds and
Records. . I
The Bob Straub Parkway (aka Jasper Road Extension) has been constructed and the right-of-
way dedicated; therefore a detailed analysis of compliance with this document is not seen as
necessary and was not prepared.
8. Annexation Agreement, including the terms and provisions thereof, between the City of
Springfield and the Crossroads Development, LLC, recorded March 02, 2005, Document No.
2005-014545, Lane County Deeds and Records.
It is our understanding that the land could not be annexed without conforming to the
requirements of this document. Because the lands are annexed, a dJtailed analysis of
I
compliance with this document is not seen as necessary and was not prepared.
9. Access Restrictions and relinquishment of all existing, future or poJntial common law or
statutory abutter's easements of access, including the terms and pro~isions thereof, as set
I
forth in instrument recorded July 18, 2007, Reception No. 2007-048812, Lane County Deeds
and Records. I
RLID did not make afull copy of this document available; however based on general
knowledge of the property and information available from other soJrces, it is known that the
document places limitations on access from the property directly to IBob Straub Parkway. At
the time this document was prepared it was expected that Quartz AJenue would be dedicated
along the south property line providing a centralized access point fJr traffic from this
subdivision and surroundinff properties. Quartz Avenue was also t6 provide a utility
corridor between South 571 Street and Bob Straub Parkway. Sincelthis document was
recorded, the city has decided to move the intended intersection apwoximately 600 feet
south. This had the spin-off effect of making it difficult for this subdivision to accomplish
street connectivity, emergency vehicle turnaround and utility connebon design criteria. The
solution selected was to use a cul-de-sac street with a limited use c6nnection through to Bob
Straub. This limited use connection will provide the utility corrido~ and meet emergency
vehicle needs. The connection will be gated at both ends to preventl use by anyone except
utility maintenance personnel (including the city and public utility stafJ) and emergency
,
vehicles. Use of this connection will be rare and not by the generaljPublic so is seen as in
compliance with the intent of the recorded document. To meet the city's length requirements
I
for dead-end streets andfire code requirements for turnarounds without this connection
would severely reduce the subdivision's density.

Dear Andy,
This is a complete submittal for the Jasper Meadows Phase 10 tentative subdivision application.
A pre-submittal meeting was held at 11 :00 on Tuesday, December 21, 2010. The items deemed
incomplete at the meeting have been addressed as follows:
FIRE AND LIFE SAFETY (Gilbert Gordon via Al Gerard)
Provide "No Parking-Fire Lane" signs or curb markings (red striping with white letters or yellow
,
striping with black letters) on one side of Quartz Avenue and both sides of the fire apparatus
,
access road from the cul-de-sac bulb to Bob Straub Parkway per 2010 Springfield Fire Code
503.2.1,503.3 and SFC Appendix D 103.6. I
The developer prefers to install signs instead of curb markings. A note has been added to the
,
plans acknowledging that the signs will need to be included in the PIP. In addition to the
written comment about the locks, it is acknowledged that there was dlso a verbal discussion
that the gates need to be designed with an effort at discouraging ped~strian use.
Provide Public Works locks on the proposed manual gates on the fire aJparatus access road. PW
locks can be obtained from Heyman's Lock, Safe and Security at 13i 14th Street in
Springfield (Phone: 541-747-6713). I
Thankyoufor providing information on how to obtain the locks. Installation of the locks will
be included in the PIP.
TRANSPORTATION (Michael Liebler)
Existing drawings are in compliance with minimum street depth to the cul-de-sac, Given that
secondary emergency access will be provided to the cul-de-sac, the rilaximum street length of
400 feet may be extended to more efficiently utilize the developable larea.
We appreciate the city's willingness to propose flexibility to make a property more
developable. Several other street and lot layout options were reviewed and determined to not
be enough improvement in salability to justifY a change in design at this stage. Date Received:

Various street trees located on the plans are too close to the street lighting according to
Springfield Engineering Design Standard 6.02.4. Street tree clearancbs will need to comply
with this code.. I
The street trees shown on the plan are a conceptualization to acknowledge that they will need
to be installed in the future. At the time they are installed, a finallochtion will be selected
that meets the applicable design criteria. The Written Statement has 'been revised to more
clearly reflect this.
A traffic impact study will not be required for this development.
Thankyoufor the confirmation.
PUBLIC WORKS ENGINEERING (Clayton McEachern)
I. Transformers and mailboxes not shown. If neighborhood mailboxes are not required for this
development please note. I
The transformer design (sizing and placement) will be performed by 'fPUD, the electric
provider, at the time of P IP preparation. A note has been added to the plans to note that
selection of a neighborhood mailbox location(s) will be coordinated 'with USPS at the time of
PIP preparation.
2. No planting plan included for detention ponds.
A note has been added to the plans stating that the planting plan will be designed as part of
the PIP and will conform with City o(Springfield design criteria.
Paving along the frontage for Lot 10 will need to be extended past that lot's driveway.
The developer agrees that the shared access should be paved to at le~st the driveway for Lot
10. It is understood that this driveway will need to be constructed (ihcludingpavingJ prior to
completion of the subdivision.
A PIP will be required for constructed S S7'h St, Quartz and all associated utilities. This will
include the emergency access road to Bob Straub. I
Thank you for ensuring the design team is aware of this requirement,
An LDAP will be required before any grading is started for Phase 10.
Thank you for ensuring the design team is aware of this requirement. As mentioned in the
pre-submittal meeting, the developer is considering utilizing a mass Wading process similar
to that used at Westwind Estates. It is acknowledged that in additioil to the written comments,
Kip Kaufmanfrom the Building Department made a verbal statemerit expressing his need to
be involved with the grading and special inspection process. I
A detailed maintenance agreement for the detention ponds will be required.
A detailed maintenance plan will be prepared and submitted with thk design information
produced during the PIP process. At the time of platting a Home o\vner 's Association will be
created and tasked with ensuring maintenance of the detention ponds. The Written Statement
has been expanded to discuss the Home Owner's Association.

.
As part of the planting plan provide a note stating that all detention basins must be protected
from compaction during construction and/or have all compaction duel to construction activities
removed.
The construction plans will reflect this construction requirement.
Quartz Avenue will probably need to be changed to Quartz (...) to reflect that it is a cul-de-sac
and not a through street.
The plans reflect the street name change.
PLANNING (Andy Limbird)
1. Name of the east-west public street serving Phase 10 cannot be "Quartz Avenue" in
accordance with adopted Lane County road naming guidelines. An dltemative name must be
selected that meets the naming guidelines.
The developer has revised the street name to Basalt Court.
2. Show the location of required traffic control signage including stop or yield-controlled
intersections and vehicle barricades/warnings. I
The plans show a stop sign/street name sign combination at the northeast corner of Basalt
Court and South 5th St. A barricade has been added to the south en1d of South 57th St.
3. Please show the size and location of proposed water mains, includinJ the connection with the
proposed fire hydrant. I
To avoid cluttering the drawing, one line was shown for the joint utility trench with a call-out
in the legend regarding which utilities will be in the trench - this includes the water main.
SUB is responsible for sizing the new line at the time of PIP preparation; therefore no size is
included on our plans at this time. The new line is proving a looped!connection between an
existing 12" line and an existing 16" line so it is assumed that the new line will be between
these two diameters.
The city is undertaking a concurrent Jasper Meadows Master Plan amendment for relocating the
"Quartz A venue" intersection, which is a necessary prerequisite bef6re the proposed Phase 10
subdivision can be platted. I
It is understood that this subdivision cannot be completed prior to completion of the Master
Plan Amendment.
Provide Knox boxes and/or Public Works locks on the gated emergency access road.
At the time of public improvement design selection of the lock will bk coordinated with
Clayton McEachern and Gilbert Gordon. I
Staff does not support installation of an 8 to 10-foot high retaining wall along the rear of Lots 10-
21. Slope-adaptive housing is recommended for these lots. I
The developer appreciates the city's suggestions and has taken them into consideration. A
discussion of this topic has been added to the Written Statement.
The proposed 4-foot high retaining wall on Lots 1-9 will likely require 'an engineered design.
Date Received:
MAR - 8' 2011
Original Submittal
.
.
The design of the retaining walls will be addressed prior to submittallfor an LDAP or mass
grading permit.
The face of the proposed 4-foot retaining wall on Lots 1-9 must be located at least two-feet
,
inside the property lines and not require maintenance access onto or through Tracts A, B or C.
,
Additionally, disturbance caused by construction and installation of the retaining wall shall
not encroach within the adjacent regulated wetlands unless proper mitigation measures are
implemented.
These requirements will be addressed at the time of wall design.
The applicant shall verify the status of wetland mitigation measures for the Jasper Meadows
neighborhood. If completed, Tract A shall be partitioned from the ddvelopable remainder on
the east side of Bob Straub Parkway (Phase 9) and dedicated to Willkalane prior to or
concurrent with the Phase 10 subdivision (ref. Jasper Meadows Mastbr Plan approval
condition #20). I
The Written Statement now includes a discussion regarding the dedication of the wetland tract
to Willamalane.
Emergency access driveway connection to Bob Straub Parkway will require a Lane County
Facility Permit or an acceptable written authorization. I
The city has previously indicated that they accept responsibility for obtaining Lane County's
approval of the change. It is our understanding that Ken Vogeney ahd Joe Leahy have made
progress on this since the Pre-Submittal Meeting.
All utilities installed to serve the subdivision shall be placed underground.
This is reflected on the plans and the PIP will conform.
A Tree Felling Permit will be required for the proposed removal oftrees within the project area.
This will be appliedfor prior to tree removal.
The subdivision proposal shall meet the cluster development standards of SDC 3.2-230.
A discussion of the cluster development standards has been added td the Written Statement.
Please feel free to contact me at 746-0637 if you or anyone else has any questions.

Stonn Drainage Evaluation
Jasper Meadows Phase 10
Introduction I
1bis evaluation was prepared to summarize the drainage system proposed for the Jasper Meadows
Phase 10 development. This storm drainage evaluation includes stormwatef quality, stormwater
quantity and detention calculations. Culvert sizing calculations are also included.
Existing Conditions
The development site is located south of Jasper Meadows Phase 6 &7 on the east side of the extension
of S. 57'h Street in Springfield, Oregon. The proposed site has an area of 3.'80 acres. The site is
currently undeveloped with vegetative cover consisting of trees, grass and blackberry patches. The site
generally drains from south to the north with slopes ranging from 3-10 perJent. The site drains toward
the existing wetlands to the north.
According to the Soils Survey of Lane County. Oregon. by the Natural Resource Conservation Service,
the soil at the site is Dixonville-Philomath-Hazeleair Complex (Soil NumbJr: 43C, Hydrologic Group:
C).
Proposed Site Conditions
The proposed site will have a public road with a cul-de-sac at the end with a gravel emergency vehicle
route. 21 lots are proposed for this development. South 57th Street will be bxtended to the south
boundary of the proposed development. Culverts will be placed under the Jxtension of South 57th
Street to provide an outlet for a large drainage basin consisting ofwetlandsJ Two detention ponds are
proposed for the site to match the pre-developed runoff rates.
Stonnwater Quality and Quantity
Existing Conditions
Storm water detention is proposed for the Jasper Meadows Phase 10 development to reduce peak
discharge rates to pre-development levels. Existing conditions peak runoffirates for the 2-year through
the 25-year storm events were generated for Jasper Meadows Phase 10. Peak discharge rates for the
pre-development conditions were generated using the Santa Barbara Unit Hydrograph method. The
King County Department of Public Works, Surface Water Management Di~sion, Hydrographs
,
Programs, Version 4.21B computer program was used to assist in the hydrologic and hydraulic
calculations.
The peak discharge rates from the existing site are summarized below. Complete calculations are
included in Appendix A.
Existing Conditions Peak Discharge Rates (cfs)
2 Year (3.3 inchesl24 hours) 0.74
5 Year (3.8 inchesl24 hours) 1.07
10 Year (4.3 inchesl24 hours) 1.42
25 Year (4.8 inchesl24 hours) 1.79
The listed existing conditions peak discharge rates were used as the maximum allowable peak
discharge rates for the post development conditions.

Storm Drainage Evaluation
Jasper Meadows Phase 10
I
The proposed site is broken up into three basins. Basin A includes lots 9-13 and the gravel emergency
vehicle roadway. Basin A has a detention pond located near lot 9. Basin B' includes the proposed
public road, a portion of the South 57th Street extension and lots 1-8 and 14t21. Basin A has a
detention pond located north oflots 1-3. Basin C is the remainder ofSouili 57th Street that can not
drain to the proposed detention pond north of lots 1-3. Basin C will be relebed undetained.
Peak discharge rates for the post development conditions were generated Jing the Santa Barbara Unit
Hydrograph methoel The King County Department of Public Works, SurfJce Water Management
Division, Hydrographs Programs, Version 4.21B computer program was u~ed to assist in the
hydrologic and hydraulic calculations.
Proposed Conditions
The water quality rates and the peak discharge rates from the proposed site are summarized below.

Proposed Detention System I
i
Basin A Detention Pond !
The detentiOn pond for Basm A has 3: I SIde slope on the Side near the gravel emergency vehicle
roadway for ease of maintenance. The other three sides will have retaining walls. The pond is planned
to have two feet of storage and I foot offreeboarel The pond bottom is at 532.00. The top of the pond
is at 534.00. The outlet will have a 2 y," diameter orifice at elevation 532.00 and an overflow set at
534.00. Basin A detention pond is approximately 3,200 cubic feet of storaie. A small berm in the
bottom of the pond creates a channel for the water quality storm. The channel is graded toward the
outlet at 0.5% and is long enough to provide for a nine minute time of residency which is the minimum
for water quality. The pond will be landscaped in accordance with the CitY of Springfield
requirements. See Appendix C for Basin A water quality calculations.
The Basin A detention pond is characterized in a spreadsheet to be used with the King County
Department of Public Works, Surface Water Management Division, Hydro~phs Programs, Version
4.21 B computer program for routing the developed storm through the detention ponel The routing
data can be found in Appendix D as well as the detained flow rates from Bkin A. . . .. .

Stonn Drainage Evaluation
Jasper Meadows Phase 10
Off-Site Stonn Water and Culvert Sizinl!: I
South 57th Street will need to be extended to provide access to the proposed Jasper Meadows Phase 10.
As shown on the off-site drainage basin figure, runoff from off site areas dnhn toward the South 57lh
Street extension. Culverts are proposed at this location.
Culvert sizing calculations were performed to determine the size and quantity of the proposed culvert
under South 57th Street. This culvert pipe will convey runoff from approxirhately 53 acres of
undeveloped land east ofWeyerhaeuser Haul Road, 45.5 acres between thelWeyerhauser haul road and
Bob Straub Parkway and 45.7 acres between Bob Straub Parkway and South 57th Street. The total
acreage of property draining to this pipe is 144 acres. It has been a consistbnt requirement in this area
for each new development to provide stormwater detention. As a conserva~ve estimate, the culvert
sizing calculations are based on the entire upstream tributary area being fully developed with no
detention, a travel time of zero will be assumed when adding hydrographs and based on the following
hydrologic assumptions: ,I

Total Runoff 132.98
The total runoff expected at the proposed South 57th Street culvert crossing is 133 cubic feet per
second. I
Culvert sizing was performed using the Culvert Design Sheet from the Oregon Department of
Transportation Highway Division Hydraulics Manual published by ODOTJ 2005 (see Appendix F for
Culvert Design Sheet and other information used for sizing).
The results indicate two 4 'x6' box culverts laid side by side with the bottom two feet buried can
convey the design flow with minimal surcharging at the entrance.
