Project: Alabama Street CulvertLocation: City of Redlands, County of San BernardinoPermit / Agreement # CDFG 1600-2006-0173-R6; ACOE 200601740-SLPAmount: $25,000.00

Project OriginQuantum Structures, LLC was required to mitigate for the construction of residential Tract17693. The development involved the construction of 77 town homes and associatedinfrastructure over 7.5 acres, in addition to widening the Alabama Street culvert which crosses ahistoric channel in the city of Redlands. This project resulted in permanent impacts to .06 acresof the channel, known locally as the Morrey Arroyo.

Amount of MitigationThe mitigation responsibilities assigned to the developer of this project consisted of .12-acres of restoration of riparian habitat within the boundaries of the Santa Ana Watershed. The small sizeof the mitigation reflected the relatively low impact of the project in comparison with otherdevelopments in the area.

LocationThis development is located within the city of Redlands, in the county of San Bernardino,precisely at 34 3 46 north, 117 12 31 west.

Purpose/ Goal of the MitigationThe purpose of the mitigation is to perform restoration work within the immediate habitat directlyaffected by the construction of the homes and widening of the culvert. Restoration of riparianhabitat typically involves eradicating existing non-native vegetation, in addition to revegetatingthe project area with native species and removing all harmful debris. These tasks are designed tostrengthen existing as well as encourage new species of native vegetation and wildlife in order torestore the functions and values of the project site to pre-disturbance conditions.

Site VisitsThe mitigation has not yet been assigned but various site visits and meetings have been made

within the City of Redlands.

Project StatusThe IERCD received the funds for this mitigation project in June of 2008. The money receivedfrom the developer will be combined with that from two other projects; together, these funds willpay for the restoration of 3.083 acres of riparian habitat restoration work in the city of Redlands.The IERCD is currently working with the city of Redlands as well as staff from the RedlandsConservancy to find appropriate placement for the mitigation. The funds will likely be applied torestoration of the Zanja channel, a historic irrigation ditch which ultimately empties into the SantaAna River.

Project: Calnev Pipeline - CajonLocation: Cajon Pass, County of San Bernardino Permit / Agreement # DFG 1600-2006-0189-R6; ACOE #200601563 SLTAmount: $40,000.00

Project OriginCalnev Pipeline Company, LLC was required to mitigate for work done to stabilize twopetroleum pipelines that cross an un-named ephemeral drainage and tributary to Cajon Creek.The stabilization work involved excavation of channel banks and bottom and installation of concrete mats over the pipelines. This work resulted in .17 acres of permanent impact tostreambed habitat.

Amount of MitigationThe mitigation for impacts to .17-acres of streambed habitat was placed off-site, and thereforeassigned at a 3:1 ratio. Calnev Pipeline Company was required to fund the restoration of .51-acres of riparian habitat located in the Cajon pass region of San Bernardino County, with aminimum of five years of follow-up maintenance and monitoring by an approved conservationentity.

LocationThe mitigation funds will be applied to a larger restoration project at Lost Lake in San BernardinoCounty. The precise location of the lake is 34 16 23 north, 117 27 55 west.

Purpose/ Goal of the MitigationLost Lake is classified as a sag pond water body, and was created by the motion of the SanAndreas Fault. The lake is surrounded by valuable coastal sage scrub and chaparral habitat;however, it is also moderately infested with invasive species including mustard ( Brassica nigra).The IERCD has conducted previous removal projects in the area, including eradicating 17-acresof giant cane ( Arundo donax), including periodic monitoring to prevent re-growth. Theapplication of funding from mitigation projects will enable the IERCD to continue restorationefforts to remove non-native species, and restore the lake to its naturally-existing habitat.

Site VisitsField Ecologist:3/05/08

Project StatusThe IERCD received the mitigation fundsfrom Calnev Pipeline Company inDecember 2006. Currently, the IERCD isawaiting the completion of the NEPAdocument authored by the United StatesForest Service in order to go forward withthe project. The IERCD field ecologist

has conducted reconnaissance in the LostLake region to determine the mostappropriate placement for the project site.The mitigation for Calnev - Cajon will becombined with two other mitigationprojects (Calnev Deadman and Calnev Swarthout) in order to maximize thefunding that can be applied to restoration efforts in the area surrounding the lake.

Project: Calnev Pipeline Deadman Junction Location: Cajon Summit, County of San BernardinoPermit / Agreement # DFG 1600-2007-0105-R6Amount: $22,500.00

Project OriginCalnev Pipeline Company, LLC was required to mitigate for impacts resulting from work performed in an attempt to stabilize a 14-inch petroleum pipeline located near Deadman Junctionin San Bernardino County. The work involved excavation around the pipeline, installation of rip-rap, and bank stabilization via construction of a retaining wall. This work resulted in .09-acres of permanent impact and .86-acres of temporary impact to an unnamed tributary to Cajon Creek.

Amount of MitigationThe mitigation for impacts to .09-acres of streambed habitat was placed off-site, and thereforeassigned at a 3:1 ratio. The total mitigation assigned was .27 acres of riparian restoration work inthe Cajon Pass area of San Bernardino, with six years of follow-up maintenance to be donefollowing the initial restoration work.

Project: Calnev Pipeline - SwarthoutLocation: Cajon Summit, County of San Bernardino Permit / Agreement # 1600-2007-0075-R6Amount: $22,500.00

Project OriginCalnev Pipeline Company, LLC was required to mitigate for impacts resulting from work performed to stabilize an existing 8-inch petroleum pipeline in Swarthout Canyon Road in SanBernardino County. The pipeline became unstable due to natural channel erosion, creating theneed for Calnev Pipeline Company to excavate around the channel, install rip-rap, and cover thearea with revetment mats. The work caused .06-acres of permanent and .02-acres of temporaryimpacts to an unnamed riparian streambed in a perennial tributary to Cajon Creek.

Amount of MitigationThe mitigation assigned to Calnev Pipeline Company due to impacts from the pipelinestabilization was .3-acres of riparian streambed restoration or enhancement. The mitigation wasrequired to be applied to a project area within the vicinity of the Cajon Summit in SanBernardino. The IERCD accepted the mitigation responsibilities, including 6 years of maintenance and monitoring following the initial work.

Project: Centex Sycamore HeightsLocation: City of Chino Hills, County of San BernardinoAmount: $120,000_________________________________________________________________________________Project Origin: Centex Homes was required to mitigate for impacts resulting from the construction of Tract 14551,commonly referred to as the Centex Sycamore Heights Development. The Tract includes 324 single-family units, 216 multi-family units, associated infrastructure, and 63-acres of open space on a 197-

acre parcel of land.

Required Mitigation:The development resulted in permanent impacts to .44 acres of waters of the United States of which.38 acres are wetland habitat, .82-acres of southern willow scrub habitat, and 8.85-acres of coastalsage scrub. The mitigation requirements consisted of preservation of 25 acres of open spaceincluding mixed woodland, elderberry woodland, and coastal sage scrub habitats, as well as 4.8-acresof created habitat, of which 3.3-acres represent a mix of riparian and wetland habitat, and 1.5-acresrepresent coastal sage scrub creation on former grassland habitat.

Location:The 25 acre mitigation is located adjacent to Chino Hills State Park on the west side of the Centex

Sycamore Heights Development. The additional 4.8 acres is located within the development.

Purpose/Goal of the Mitigation:Twenty-five acres of habitat have been conserved in perpetuity as a result of impacts stemming fromconstruction of Tract 14551. The conservation easement will ensure continued protection of the on-site sage scrub, woodlands, and riparian vegetation suitable for local species of wildlife, including theleast Bells vireo ( Vireo bellii pusillus) and California gnatcatcher ( Polioptila californica). Thepreserved area will serve as a buffer between the project site and Chino Hills State Park in order toprotect species of vegetation and wildlife from excessive human contact.

Site Visits:Field Ecologist:3/11/08, 8/01/08, 12/09/08

Project Status:The field ecologist visits the site at a minimum of three visits per year in order to monitor illegalactivities, remove any site refuse, and locate and plan for the removal of invasive species located on-site. On November 15 th 2008, the Freeway Fire burned a total of 13,102 acres. The fire did impactthe 25-acre conservation easement. IERCDs field ecologist is currently coordinating with ChinoHills State Park staff to determine if post-fire restoration efforts are necessary. The IERCD is in theprocess of determining whether or not to take ownership of the 4.8-acre riparian/wetland site. Thesuccess criteria for the 4.8 acre portion are not yet completed.

Project: Century Vintage Homes: Wildwood I Location: City of Yucaipa, County of San Bernardino Permit/Agreement CRWQCB #R8-2004-0110; CDFG # unavailableAmount: $87,000.00

Project OriginCentury Vintage Homes was required to mitigate due to construction of Tract 15548, a singlefamily residential development consisting of 63 lots and related infrastructure. The constructioninvolved the widening of an access road into the development, which resulted in .03-acres of fillinto an un-named perennial tributary to Yucaipa Creek.

Amount of Mitigation The mitigation for this project was assigned to Century Vintage Homes at a ratio of 3:1, totaling.09-acres. The IERCD accepted the responsibility to facilitate the mitigation, which was requiredto involve restoration of habitat within the Santa Ana River Watershed. IERCD received $87,000in March 2005.

Location Originally the mitigation project was going to take place within the city of Yucaipa on anunnamed tributary to Wildwood Creek. However, issues related to creek stabilization as well as

discussions with the City of Yucaipa have resulted in a change in the mitigation location. Thefunds will now be combined with those from the Century American and Century Vintage Homes:Wildwood II projects; together, they will be applied toward the creation of two vegetated lineardrainages planned for the existing 13 th Street Park in Yucaipa.

Purpose/Goal of MitigationThe purpose of this restoration requirement is to mitigate for impacts to Yucaipa Creek stemmingfrom the construction of Tract 15548. The addition of valuable native habitat resulting fromrestoration tasks such as removal of non-natives and replanting with natives provides food andshelter for area wildlife. The increase in beneficial native acreage increases the chances of survival for local species of vegetation and wildlife.

Site Visits District Manager:4/23/08, 6/04/08Project Manager:4/23/08, 6/04/08

Project StatusThe funding received from the Century Vintage Homes will be combined with funding from twoother mitigations and used to perform riparian restoration work at the 13 th Street Sports Park inthe City of Yucaipa, County of San Bernardino. The area that has been set aside for therestoration will be graded this summer, with planting and irrigation installation set to take place inthe fall of this year.

Project: Devil Canyon (Rialto Channel), San Bernardino County Flood Control DistrictLocation: City of San Bernardino, County of San BernardinoPermit / Agreement # ACOE 200201259-GS

Project OriginThe San Bernardino County Flood Control District was required to mitigate for impacts resultingfrom the concrete channelization of the Rialto Channel, an ephemeral riparian system that is atributary to the Santa Ana River.

Amount of MitigationThe IERCD received $61,575.00 in July 2006 which was required to be used for 3.3-acres of removal of giant cane ( Arundo donax) within the Santa Ana River watershed.

LocationThe east and west forks of Devil Canyon, a tributary to the Santa Ana River, were chosen forapplication of funding earmarked for giant cane removal. The site was chosen based on itsproximity to the location of original project impacts. It is precisely located at 341057 north,117 19 47 west.

Purpose/ Goal of the Mitigation

The purpose of this mitigation project is to remove the highly invasive giant cane, a non-nativeplant which has become extremely problematic in the southern half of the United States,including the Santa Ana River Watershed region of California. The removal of giant cane alongdrainages in the watershed increases the quality and quantity of water entering the Santa AnaRiver, as well as encourages regeneration of native species of vegetation. In addition to the giantcane eradication, the IERCD will also be targeting other harmful invasives including tree of heaven ( Ailanthus altissima), tree tobacco ( Nicotiana glauca),tamarisk (tamarix ssp.),andcastorbean ( Ricinus communis). The removal of harmful non-native species assists in the returnof native species of vegetation and wildlife to the acreages being restored by the IERCD.

Site VisitsThe Rialto Channel project has been combined with the San Sevaine project; therefore, the site

visits listed here are therefore also applicable to the San Sevaine section of this report.

Project StatusAll of the targeted invasives have been removed from the project site, first by cutting all existinggrowth, and then spraying to prevent any re-growth. Currently, the non-native species presence isless than 10% on-site, and the contractor is in the first year of the 3-year herbicide treatment thattypically follows the physical removal of vegetation. Following the three-year treatment withherbicide, the site will be actively monitored for any re-growth for the next twenty years viaquarterly site visits by the IERCD field ecologist. Any re-growth of invasive species targeted

during this removal effort will be eradicated through cutting and treating with herbicide.

Project: ESRI Parking LotLocation: City of Redlands, County of San BernardinoPermit / Agreement # DFG 1600-2006-0219-R6, ACOE SPL-2006-1906Amount: $150,000.00

Project OriginESRI was required to mitigate for impacts related to reach modification of the Mission Channel,performed in anticipation of the expansion of the parking area associated with the EnvironmentalSystems Research Institute (ESRI) in Redlands.

Amount of MitigationThe ESRI parking lot expansion project resulted in the loss of 1.48-acres of streambed associatedwith the Mission Channel in Redlands. For these impacts, ESRI was required to mitigate at aratio of 2:1, resulting in a total of 2.96-acres of riparian restoration required. ESRI remitted adeposit on April 16 th 2007 in the amount of $2000. IERCD received the full mitigation funds inthe amount of $148,000.00 in June of 2007.

Purpose/ Goal of the MitigationThe goal of this mitigation assignment is to perform restoration on acreage in the watershed thatlies in close proximity to the site of the original impacts. The motivation behind this practice isthat the native wildlife and vegetation that were disturbed by the project will benefit from themitigation work. Restoration, enhancement, and/or creation of functional native habitat placedfar from the site of project impacts is not favored because is does not provide benefit to theseimperiled species.

Site VisitsVarious site visits and meetings were conducted in 2008 to determine mitigation location withinthe City of Redlands.

Project StatusThe money received from ESRI will be combined with that from two other projects; together,these funds will pay for the restoration of 3.083-acres of riparian habitat restoration work in the

city of Redlands. The IERCD is currently working with the city of Redlands as well as staff fromthe Redlands Conservancy to find appropriate placement for the mitigation. The funds will likelybe applied to restoration of the Zanja channel, a historic irrigation ditch which ultimately emptiesinto the Santa Ana River.

Project: Four Seasons BeaumontLocation: City of Beaumont, County of RiversidePermit / Agreement #: DFG 1600-2004-0010-R6; ACOE 2004-00619-DPS

Project Origin: K-Hovnanian Homes was required to mitigate due to impacts from the construction of the FourSeasons Beaumont development, a retirement community consisting of residential units andassociated infrastructure on approximately 565.5-acres. The project resulted in permanent andtemporary impacts to habitat associated with Portrero Creek and a tributary to Portrero Creek,both of which ultimately connect with San Timoteo Creek, a tributary to the Santa Ana River.

Amount of MitigationFor impacts stemming from the creation of Four Seasons Beaumont, K-Hovnanian Homes wasrequired to restore, enhance, and/or create approximately 27-acres of the project site; thisincluded 10.55-acres of riparian habitat, 12.3-acres of non-irrigated upland, and 3.96-acres of wetlands consisting of eight basins and one bioswale.

LocationThe project site is located in the city of Beaumont, in the County of Riverside, at 33 54 56north, 116 57 1 west. The wetland, riparian, and upland portions of the collective mitigationsites are entirely included within the project area.

Purpose/ Goal of the MitigationThe construction of this Four Seasons development resulted in impacts to a variety of habitats, aswell as the native species of wildlife and vegetation existing within those natural communitiesincluding California buckwheat ( rigonum fasciculatum),black sage ( Salvia mellifera), mulefat( Baccharis salicifolia), and willow ( Salix spp.). The design of the assigned mitigation is meant toavoid an overall decrease in area jurisdictional acreage, as well as to restore the functionality of the habitat that was disturbed but not eliminated due to construction activities. Finally, the areasthat were temporarily, rather than permanently impacted will be restored to a state that is at leastequivalent to what existed pre-creation of Four Seasons Beaumont. These restoration activitieswill ensure that there are adequate resources available for area wildlife and vegetation even in the

face of continued development.

Project: Goose Creek Golf Course Construction of Unauthorized BermLocation: Mira Loma, Riverside CountyPermit / Agreement # CDFG 1600-2007-0093-R6Amount: To be determined

Project OriginGoose Creek Golf Course was required to mitigate for unauthorized construction of an earthenberm on the southeastern portion of their property, adjacent to the Santa Ana River. The bermmeasured approximately 34 feet wide, 8.5 feet high, and 2200 feet in length for a total area of 1.77 acres, and was created in order to protect the course from flooding during anticipated futurestorm events. The 1.77-acres of permanent impacts were in addition to approximately 2-acres of temporary impacts occurring as a result of collection of riverbed sediment for berm construction.

Amount of MitigationThe mitigation assigned for impacts to the Santa Ana River involved restoration of the bermcreated by Goose Creek. Course staff were instructed to remove all non-native vegetation fromthe berm including mustard ( Brassica nigra), giant cane ( Arundo donax), poison hemlock (Conium maculatum), tree tobacco ( Nicotiana glauca), and ragweed ( Ambrosia artemesifolia).Following that, they were required to revegetate with native riparian/upland transitional specieswhich they chose to propagate in an on-site nursery from cuttings taken from local species,including arroyo willow ( Salix lasiolepis), sandbar/narrowleaf willow ( Salix exigua), red willow(Salix laevigata), black willow ( Salix gooddingii), cottonwood ( Populous fremontii), and mulefat( Baccharis salicifolia). Goose Creek is also being required to record a conservation easement infavor of the IERCD consisting of approximately 55-acres of existing riparian/upland transitionalhabitat adjacent to the Santa Ana River.

LocationThe mitigation is located in the area adjacent to the Santa Ana River, in the city of Mira Loma,County of Riverside, precisely at 33 58 1.56 North, 117 31 41 West.

Purpose/ Goal of the MitigationThe creation of the earthen berm on golf course property disturbed habitat identified as ideal

territory for the endangered least Bells vireo ( Vireo bellii pusillis), in addition to existing speciesof willow and cottonwood trees. The goal of the revegetation effort is to increase the currenthabitat value to that of the habitat that existed pre-berm creation. The removal of invasivespecies and the revegetation with native species on the berm will encourage the establishment of a functional riparian/upland community.

Project OriginDue to several years of high flow velocity through the creek, the existing detention basin was nolonger effectively preventing widespread sediment dispersal during storm events. The coursedesired to remove excessive sediment as well as vegetation existing in the basin in order torestore it to proper functionality. Approximately 10,000 cubic yards of sediment as well as 6-7mature willow trees were slated for removal, with resulting impacts predicted to affectapproximately 1.5-acres of the creek bank.

Amount of MitigationThe mitigation assigned for this detention basin maintenance will involve revegetation of thecreek banks in the locations which suffered impacts from the project. Goose Creek elected topropagate cuttings from the trees slated for removal to be used in the revegetation process.Additionally, course staff has been required by DFG to replace the mature willows removed at aratio of 5:1, with cuttings also taken from local specimens.

Location

The mitigation is located in Day Creek, city of Mira Loma, County of Riverside, precisely at 3358 1.56 north, 117 31 41 west.

Purpose/ Goal of the MitigationThe goal of the restoration of the detention basin is to reduce the overall amount of sediment inthe creek; this movement causes erosion and sediment transfer into the adjacent Santa Ana River.The goal of revegetating the banks of the creek where the sediment basin work will take place isto restore the functionality of the riparian habitat in the project area. The removal of trees fromthe creek bank has the potential to impact the habitat available to wildlife species, as well as toincrease erosion. Revegetation along the banks is thought to reduce the consequences of this treeremoval.

Project StatusThe Goose Creek Golf Course is awaiting the latest draft of the permit allowing the work requested to be done in the existing sediment basin. The IERCD is working with staff fromGoose Creek, the Santa Ana Watershed Association (SAWA) and the DFG in order to assist withthe removal of existing trees and the revegetation along the creek banks with native riparianspecies. The tree removal and detention basin maintenance is scheduled for mid-September of 2009.

Project: Nevada Business Park Location: Redlands, San Bernardino CountyPermit / Agreement # CDFG 1600-2007-0079-R6Amount: $15,000.00

Project OriginRossmore Enterprises was required to mitigate due to the creation of an industrial/commercialdevelopment in the city of Redlands. Five buildings total were constructed in addition toassociated infrastructure and landscaping over approximately 16-acres. The project resulted in.00127-acres of permanent and .0007-acres of temporary impacts to the Zanja Channel, a historicirrigation ditch and tributary to the Santa Ana River.

Amount of MitigationThe mitigation assigned to Rossmore Enterprises totaled only .003-acres of riparian restorationwithin the watershed due to the relatively small size of the project impacts. As a result, theIERCD chose to include this restoration acreage with two other mitigation projects in order toincrease the benefit of having all three projects combined. The total area of the three projects is3.083-acres.

Location

The impact occurred southeast of the intersection of Nevada Street and Park Avenue in the city of Redlands, county of San Bernardino. The mitigation will be located in the general vicinity of thefollowing coordinates: 34 3 10 north, 117 12 52 west.

Purpose/ Goal of the MitigationThis mitigation is unique in that it is labeled as a micro-mitigation, meaning that it is a smallamount of mitigation resulting from a very low amount of permanent impact from the project.The funds received from the developer are quite small as a result, so they will be applied to acollective fund that will be applied to restoration work in the Zanja Channel in the city of Redlands.

Site Visits

Various site visits and meetings were conducted in 2008 to determine mitigation location withinthe City of Redlands.

Project StatusThe IERCD received the funds for this mitigation project in July of 2007. The money receivedfrom the developer will be combined with that from two other projects; together, these funds willpay for the restoration of 3.083-acres of riparian habitat restoration work in the city of Redlands.The IERCD is currently working with the city of Redlands as well as staff from the RedlandsConservancy to work in the Zanja channel, a historic irrigation ditch which ultimately emptiesinto the Santa Ana River.

Project: ProLogis Beaumont Location: City of Beaumont, County of RiversidePermit / Agreement # CDFG 1600-2004-0118-R6, ACOE 200401611-WJC

Project OriginFourth and B, LLC (on behalf of ProLogis) was required to mitigate for impacts stemming fromthe creation of the Crossroads Logistics Center industrial park in the city of Beaumont, county of Riverside. The construction of the Crossroads development resulted in impact to 2.8-acres of streambed habitat, the fill of two seasonal pools, and the removal of 41 scrub oak ( Quercusberberidifolia) trees from the project site.

Amount of MitigationThe assigned mitigation resulting from the creation of the industrial park consisted of restorationof a 9-acre parcel of land called the conservation area immediately adjacent to the project sitein the city of Beaumont. Within the conservation area, Fourth and B, LLC was required to createone acre of scrub oak ( Quercus berberidifolia) and chamise ( Adenostoma fasciculatum) habitat,.11-acres (490 square feet) of ephemeral pond habitat, and were also required to replace theremoved trees at a ratio of 2:1, resulting in the planting of 82 scrub oak trees. The rest of theconservation area was to be revegetated with native riparian and upland transitional species aswell as relieved of all non-native species. The completion of tasks associated with creation of theconservation area was to be done without impacting the adjacent Coopers Creek which lies to thesouth of the mitigation site. Finally, an easement over the area was required in order to protectthe property in perpetuity.

LocationThe Conservation area is located south of the 60 freeway, and west of Fourth Street in the city of Beaumont, and the county of Riverside. The precise location is 33 55' 37.6458" north, 117 0'39" west.

Purpose/ Goal of the MitigationThe purpose of the mitigation is to ensure continued availability of habitat for the species of wildlife and vegetation that populate the site of the original project impacts. One particular

species of concern is the seasonal Riverside fairy shrimp ( Streptocephalus woottoni), potentiallyimpacted during construction by the filling of two ephemeral ponds which provide habitat for thisspecies. The developer was required to replace one of the pools in order to ensure continuedavailability of habitat for the fairy shrimp. The revegetation of the conservation area also focusedon reestablishing critical native species including the scrub oak, whose presence in this region hasbeen threatened by continual development of open land.

Site Visits District Manager:6/26/08Project Manager:6/26/08, 7/08/08/, 11/17/08Field Ecologist:2/13/08, 4/17/08

Project StatusCurrently, the conservation area has been created; however, due to a clerical error it is .55-acresless than the 9 acres required by the regulatory agencies. As a result, Fourth and B, LLC isexploring opportunities for the conservation and protection in perpetuity of this additionalacreage. The easement draft for the existing 8.45-acre conservation area has been completed byIERCD legal counsel; however, the progress of the project has been halted pending the creationof a system for an alternative funding mechanism for easements by staff from the city of Beaumont.

Project: ProLogis OntarioLocation: City of Ontario, County of San BernardinoPermit / Agreement # CDFG 6-2002-297, ACOE 2001-646-RRS, CRWQCB 36-2002-32-DGW

Project OriginThe Catellus Operating Limited Partnership (on behalf of ProLogis) was required to mitigate forimpacts related to the construction of the ProLogis Crossroads Business Park in the city of Ontario and county of San Bernardino. The development of the park resulted in the addition of 13.2-acres of permanent fill to the East Etiwanda Creek and unnamed drainages, all of whom aretributaries to the Santa Ana River.

Amount of MitigationFor impacts to the creek and associated drainages, Catellus was required to create both a 1.5-acreon-site water quality basin as well as a 4-acre vegetated linear drainage adjacent to the easternedge of the park. In addition to these measures, Catellus was also required to purchase 9.5-acresof mitigation credits from the Cajon Creek Mitigation Bank.

LocationThe project site is located north of Ontario Mills Parkway and west of Etiwanda Avenue in thecity of Ontario and county of San Bernardino. The precise location of the development is 34 4'20.478" north, 117 31' 40.0434" west.

Purpose/ Goal of the MitigationThe mitigation measures assigned as a result of impacts from the ProLogis Crossroads BusinessPark are meant to have two purposes. First, the creation of the vegetated linear drainage as wellas the contribution to the mitigation bank is meant to offset the loss of valuable upland/ripariantransitional acreage due to the parks creation. The heavily industrialized city of Ontario is shorton the natural habitat required to sustain native wildlife; the addition of 4-acres of open spacevegetated with native vegetation will help to ensure survival of the species that depended on EastEtiwanda Creek for their continued existence. Second, the drainage will act as a conduit fornuisance flows that are projected to increase as the area around the project site continues to bedeveloped. Water that passes through the drainage will also have the added benefit of undergoing

filtration through native species before exiting the area.

Site Visits District Manager:6/02/08Project Manager:6/02/08

Project StatusCurrently, ProLogis is experiencing negative effects from the downturn of the economy, bothstatewide and nationally. As a result, the business park construction is being delayed, andtherefore the construction of the linear drainage and basin is also being delayed. Attorneys forCatellus and the IERCD have been working together to draft an acceptable conservation easementfor the 4-acre drainage; however, in the meantime, both parties have agreed that a Memorandum

of Understanding should be drafted in order to keep all parties bound to the project until it is timefor construction and easement recording.

Project: Riverside Flume Pipeline Location: City of Riverside, County of RiversidePermit / Agreement # 1600-2007-0143-R6

Project OriginThe city of Riverside was required to mitigate for temporary impacts to .92-acres of riverbedhabitat resulting from stabilization work done to two water supply pipelines. The tasks associatedwith this project included removal of current pipelines, creation of a trench, and reinstalling tworeplacement pipes. The impacts from the project took place at the historic Riverside Canal FlumeCrossing site over the Santa Ana River.

Amount of MitigationThe city is required to perform onsite restoration in the project area consisting of replacing thesediment moved during pipeline stabilization, as well as re-seeding the banks of the project areawith native species. Once the project commences, public access to the area will be restricted inorder to preserve the restoration work being performed on-site. The city is also required tomitigate off-site through locating a suitable site for restoration of the endangered Santa Ana Riverwoolly star ( Eriastrum densifolium sanctorum)at a 1:1 ratio for a total of .92-acres.

Location

The mitigation will be placed within the Santa Ana watershed, near to the project site which islocated at approximately 34 3 9.7 north, 117 19 47 west.

Purpose/ Goal of the MitigationThis mitigation has two objectives; the first is to restore the project site, including replacingsediment that was moved during the course of construction, as well as to revegetate banks of theSanta Ana River to facilitate restoration of native habitat. The second goal is to ensure no netloss of suitable habitat for the Santa Ana River Wooly Star ( Eriastrum densifolium sanctorum), aFederal and State endangered species that occurs along the banks of the Santa Ana River. TheIERCD will facilitate the .92 acres of restoration in the Santa Ana River, which includes findingan appropriate site as well as ensuring successful re-establishment of the woolly star.

Site Visits District Manager: 9/11/08

Project StatusThe pipeline stabilization has been completed, in addition to the restoration work done on-site.Due to the unique nature of the requirements of Santa Ana River wooly star restoration, locatingan appropriate site has proven to be quite difficult. The IERCD is working with personnel fromthe San Bernardino County Flood Control District, the Army Corps of Engineers, and the city of Riverside in order to find a suitable location for restoration to occur. Once the site is determined,an agreement will be recorded between the IERCD and the city, in addition to an easementrecorded over the acreage in order to conserve the site in perpetuity.

Project: SunCal PulteLocation: City of Beaumont, County of RiversidePermit / Agreement # CDFG 1600-2330-5057-R6 and 1600-2004-0021-R6; ACOE 163-870AKV

Project OriginSunCal Companies was required to mitigate for the construction of tentative tract map 31462, inwhich 3300 residential units were constructed over the course of a four-phase process. Thisdevelopment resulted in 1.48-acres of permanent impacts to jurisdictional areas vegetated withspecies including mulefat ( Baccharis salicifolia), willow ( Salix spp.), and cottonwood ( Populous fremontii) marsh habitat and 2.022-acres of temporary impacts. In the course of the construction,best management practices failed and foreign materials, mud and silt were allowed to pollute thewaterway, resulting in additional mitigation due to the violation.

Amount of MitigationThe mitigation consists of creation of a 4.9 acre wetland drainage consisting of 2.2 acres of freshwater marsh and southern willow scrub habitat, and 2.7 acres of riparian woodland. Thishabitat has been planted, and will be irrigated through the end of its second year in existence; atthe end of the fifth year, pending approval from the Department of Fish and Game, a conservationeasement will be recorded in favor of the IERCD. The IERCD will also record an easement overthe 11.1 acre existing wetland that was added to the mitigation requirements as a penalty for theviolations that occurred during the construction process.

LocationThe 4.9 acre created wetland is located within the SunCal development among the residentialunits; the 11.1 acre unit lies to the east of the development, across Palmer Ave, adjacent to thegolf course. The precise location is 33 57 41 north, 117 3 11 west.

Purpose/ Goal of the MitigationThe goal of the mitigation is to replace the wetland and riparian habitat destroyed during theconstruction of tract map 31462. Habitat loss, particularly what is classified as wetland habitat,can cause changes in migratory patterns of birds, in local climate patterns, and in the make-up of

plant and animal populations; for these reasons, it is imperative that wetland acreages destroyedor altered during the course of development be repaired or re-created elsewhere. The 4.9 acrecreated wetland was planned and implemented for this purpose. The addition of the 11.1 acrewetland to be conserved in perpetuity was a result of a violation by the developer.

Site VisitsProject Manager:4/08/08, 4/17/08Field Ecologist:4/17/08, 4/22/08

Project StatusThe created wetland is in year 3 out of the 5required for the monitoring process. The IERCDhas met with project consultants and submittedendowment estimates, both for the 4.9-acre wetlandas well as the 11.1-acre wetland; however, there hasbeen no positive response from SunCal due tofinancial issues. Currently, the IERCD hasdiscontinued work on this project pending a changein the ability of the developer to afford the cost of the endowments.

Project: Sunlite StorageLocation: City of Calimesa, County of RiversidePermit / Agreement # ACOE SPL-2006-1717-CLM

Project Origin:The mitigation for this project resulted from the proposed construction of a self-storage facilityconsisting of 92,712 paved feed of storage, as well as a managers residence and a 46 spacerecreational vehicle storage area. In order to construct the storage facility, the developer willpermanently impact .03 acres of an ephemeral drainage, a tributary to San Timoteo Creek andultimately to the Santa Ana River.

Required Mitigation:This is a unique mitigation in that the developer is required to record a conservation easementover a 3 acre parcel of land encompassing an ephemeral drainage; however, there is noendowment. The relatively small size of the projected impact allows for a reduced mitigationresponsibility; however, the developer of the storage facility will be required to fund the creationand recording of a conservation easement over the property. This will allow the IERCD to ensureconservation of the property in perpetuity.

Location:

The mitigation will take place adjacent to the proposed storage site, off of Desert Lawn Drive inthe city of Calimesa.

Purpose/Goal of the Mitigation:The goal of the mitigation is to ensure that there will be acreage consisting of native species of vegetation that will provide sustenance to local species of wildlife that previously depended onthe project site for survival. Additionally, it will increase the acreage that exists in the currentwildlife corridor shaping up between Norton Younglove and the Sunlite development. The largersize of the corridor will increase the overall value of the protected acreage.

Site Visits: District Manager:2/25/08Project Manager:2/25/08

Project Status:This project is on hold pending the ability of the developer to afford to begin phasing inpreparation for construction of the storage facility. Currently, the IERCD is waiting to moveforward with this project until the construction of the storage facility begins.

Project: Wilson Creek/Oak Glen BasinsLocation: City of Yucaipa, County of San BernardinoPermit / Agreement # DFG 1600-2006-0011-R6, ACOE 2006-510-GS

Project Origin:The mitigation resulted for permanent impacts totaling .32-acres related to the development of theOak Glen Creek Desilting/Detention Basins Project, in Oak Glen Creek. The project is incooperation with the City of Yucaipa, San Bernardino County Flood Control District and theYucaipa Valley Water District.

Required Mitigation:The U.S. Army Corps of Engineers required the City of Yucaipa to dedicate a two-acreconservation easement due to impacts from construction of the basins. The San BernardinoCounty Flood Control District owns the land over which the easement will be recorded and hasagreed to donate it for mitigation purposes; however, the city of Yucaipa will need to provide theendowment for the maintenance and monitoring in perpetuity.

Location:The conservation easement is located in the City of Yucaipa, within the Oak Glen Creek channel,north of Bryant Street.

Purpose/Goal of the Mitigation:The purpose for the mitigation is to ensure the existence of like habitat in exchange for theacreage lost in the course of creating the basins. The permanent protection of the habitat locatedin close proximity to the site of the original impacts will help to ensure continued support of thearea species of native wildlife and vegetation that depend on area natural resources for survival.

Site Visits:Field Ecologist:3/25/08 District Manager and IERCD Board Members5/13/08

Project Status:Attorneys from the IERCD,city of Yucaipa, and the SanBernardino County FloodControl District have allcollaborated on the creationof an acceptable easementdraft. Currently, the IERCDhas completed the endowmentestimate and is waiting forfinal word from all partiesthat the easement language isacceptable. Once theeasement is recorded, theIERCD will begin in-perpetuity maintenance andmonitoring of the easementsite.
