Project: Century AmericanLocation: City of Yucaipa, County of San BernardinoPermit / Agreement # ACOE200501150-WJC

Project Origin

Century American Development Corporation was required to mitigate for fill material on up to 0.1 acres of waters of the U.S.

onjunction with the development of 36 single-family homes on 38.47 acres, in unnamed tributaries to the Yucaipa Creek locan the city of Yucaipa, San Bernardino County.

Amount of Mitigation

The Inland Empire Resource Conservation District (formerly East Valley RCD) received mitigation funds in the amount of24,000.00 on November 1, 2005. The money will be used for non-native species control as well as long-term management an

habitat monitoring on 0.48 acres in the Santa Ana Watershed

Location

The IERCD had previously assigned this mitigation to be applied to restoration efforts in Yucaipa Creek; however, due to issuwith stability and longevity, the creek restoration effort is currently on hold. The funds will instead be applied to restorationfforts along the perimeter of 13th Street Park in Yucaipa.

Purpose/Goal of MitigationThe purpose of this mitigation is to contribute to the restoration of habitat along the perimeter of the 13th Street Sports Park inYucaipa. Tasks associated with this type of mitigation can include eradication of invasives, replanting of natives, and associatmonitoring and maintenance to ensure habitat success.

Site VisitsNot applicable in 2007

Project Status

There have been several sitesonsidered in the course of

ttempting to determine anppropriate location for thepplication of the mitigationunds for this project. Recently,he city of Yucaipaommunicated the need fordditional funding in restoringnd enhancing habitat adjacento a planned sports park on theorner of 13th street and

Project: Century Vintage Homes: Wildwood ILocation: City of Yucaipa, County of San BernardinoPermit/Agreement # CRWQCB R8-2004-0110

Project Origin

Century Vintage Homes was required to mitigate due to drainage fill and the replacement of a culvert on Holmes Street located

he City of Yucaipa, County of San Bernardino.

Amount of MitigationThe Inland Empire Resource Conservation District (formerly East Valley RCD) received $87,000.00 on March 15, 2005 to be

sed in habitat restoration in the Santa Ana Watershed.

LocationOriginally the mitigation project was going to take place within the city of Yucaipa on an unnamed tributary to Wildwood CreHowever, issues related to creek stabilization as well as discussions with the City of Yucaipa have resulted in a change in ourmitigation location. The funds will now be combined with those from the Century Vintage Homes: Wildwood II development

sed toward restoration efforts in the13th Street Park in Yucaipa.

Purpose/Goal of MitigationThe Century Village Home Development was required to mitigate for impacts to drainage in Yucaipa. Several mitigation optiwere presented, and the regulatory agencies allowed for several mitigation options. The restoration of existing habitat as well reation of additional riparian habitat will both advance the mission of the IERCD which is maximizing native habitat restorat

within district boundaries.

Project: Southern California Regional Rail AuthorityLocation: Santiago Creek, County of OrangePermit / Agreement # CDFG 1600-2004-0014-R5

Project Origin

The Southern California Regional Rail Authority was required to mitigate .37 acres due to permanent impact construction at

Santiago Creek bridge/Santa Ana 2nd main track.

Amount of MitigationThe Santa Ana River Trust Fund received $21,000 in June of 2004.

LocationThe mitigation is also in Irvine Park. The project consists of the restoration of .37 acres of riparian habitat on Santiago Creek,ocated in Orange County. The mitigation location is at 334802N and 1174538W. The mitigation is located in habitat,

which contains mixed vegetation such as cottonwoods, willows, coastal sage scrub and mulefat.

Purpose/ Goal of the Mitigation

n restoration projects, the purpose is to return the project area to its natural state; the first step in such endeavors is often to

emove nonnative species from the site. In this project, the nonnative targeted was giant cane (Arundo donax), whose removalwas performed in order to restore the stream back to its natural native condition. Removal of giant cane also reduces fire hazalong with conserving water. Portions of Santiago Creek are rich with willows, mulefat, costal sage and elderberry. By removhe invasives the natives will flourish, thus creating better habitat for the local wildlife.

Site VisitsVisits to the Orange Countymitigation sites took place on theollowing dates: 2/13/07, 5/3/07, and/26/07

Project Status

The mitigation was completed mainlyy hand removal because the giantane was mixed in with nativeegetation; when this occurs,

machines cannot typically be usedecause of the chance that valuableatives will end up being removed

with the targeted invasives. Theroject is in the spray and monitoringhase and is monitored on a quarterlyasis. As of December 2006,4,525.89 has been spent on this

mitigation site.

Project: Centex Sycamore HeightsLocation: Chino Hills, County of San BernardinoAmount: $120,000

Project Origin

Centex Sycamore heights was required to mitigate due to the construction of a 324-lot single family home development and a nit multi-family residential development in the City of Chino Hills, county of Riverside.

Required MitigationThe development resulted in permanent impacts to .44 acres of waters of the United States of which .38 acres are wetland habiThe mitigation requirement consisted of preserving 25 acres of open space. An additional 5.3 acres of mitigation is also requirwhich consists of first flush basins and a coastal sage scrub conservation area. Inland Empire Resource Conservation District

ot accepted the 5.3 acre mitigation site at this time.

Location

The 25 acre mitigation is located adjacent to Chino Hills State Park on the west side of the Centex Sycamore HeightsDevelopment. The additional 5.3 acres is located within the development.

Purpose/Goal of the MitigationThe 25 acre conservation easement is intended to maintain habitat on-site contiguous with offsite preserves, and reduce theragmentation effects of the proposed project. There are many conservation organizations currently working to secure and

maintain large, contiguous easements rather than several scattered pieces of protected habitat; connected pieces of habitat tende more valuable to species of wildlife and vegetation as they provide more food, shelter, and ultimately genetic diversity. Thasement in Chino Hills contains a mosaic of sage scrub, woodlands, and riparian vegetation, all native plants existing in long,inear established communities. The overall goal of the IERCD is to preserve this piece of valuable habitat in perpetuity.

Project: Nevada Business ParkLocation: City of Redlands, County of San BernardinoPermit / Agreement # CDFG 1600-2007-0079-R6

Project Origin

Rossmore Enterprises was required to mitigate for impacts stemming from the construction of five industrial and commercial

uildings on a 15.76 acre site. The storm drainage plan associated with the industrial/commercial park calls for construction onfrastructure that will ultimately cause .00127 acres (55 square feet) of permanent impacts to the Zanja Creek, an ephemeral

drainage and tributary to the Santa Ana River.

Amount of MitigationThe total acreage assigned to Rossmore Enterprises was .003 acres of mitigation to be fulfilled offsite. The funds received fromRossmore will be applied to the restoration, maintenance, and monitoring of the Morey Arroyo in Redlands. Inland Empire RCeceived $15,000 in May 2007.

LocationThe impact occurred southeast of the intersection of Nevada Street and Park Avenue in the city of Redlands, county of SanBernardino. The mitigation will be located in the general vicinity of the following 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 small amount of mitigation resultingrom a very low amount of permanent impact from the project. The funds received from the developer will are quite small as esult, so they will be applied to a collective fund that is being used to restore the historic Morey Arroyo canal in Redlands.

Project Origin

The California Department of Transportation was required to mitigate for direct and indirect impacts to the least Bells vireo

Vireo bellii pusillus), a Federal and State endangered species, and its habitat as a result of construction related to the replacemf the Chino Creek Bridge.


The mitigation consists of the creation of one acre of riparian willow (Salix spp)/mulefat (Baccharis salicifolia) habitat within Prado Basin in the county of Riverside. The creation involves the removal of nonnatives including eucalyptus trees. The acrehen replanted with native riparian species, then allowed to achieve plant establishment with supplemental irrigation if necessa

The final stage involves three years of monitoring, followed by approval of successful achievement of mitigation goals by theDepartment of Fish and Game. During the five years of creation, brown-headed cowbird (Molothrus ater) traps will be placedhe area of creation. Inland Empire RCD will receive $105,000 in the beginning of 2008. The invoice was sent to Caltrans in 007.

LocationThe unincorporated territory encompassing the Prado Basin, in the county of Riverside, precisely at 33 55 33 North, 117 3

Project: Goose Creek Golf Course Construction of Unauthorized BermLocation: City of Mira Loma, County of RiversidePermit / Agreement # CDFG 1600-2007-0093-R6

Project Origin

Goose Creek Golf Course was required to mitigate for unauthorized construction of a berm on their property, which was built

rder to protect the course from storms and floods. The total permanent impact of the berm was 1.77 acres, in addition topproximately one acre of river bed that was temporarily impacted when it was removed to help construct the berm.


For impacts resulting from berm construction to Day Creek, a tributary of the Santa Ana River, Goose Creek Golf Course wasequired to perform the following: remove the nonnatives from the berm and revegetate with native riparian trees and herbaceohrubs; erect signs and fencing to prevent public access; record a conservation easement in favor of the Inland Empire Resourc

Conservation District over the jurisdictional areas adjacent to the berm to protect the area in perpetuity. Goose Creek may alsohoose to revegetate the floodplains immediately adjacent to the berm in order to help stabilize the project site in the case ofevere weather; however, this is optional and is not required by the Department of Fish and Game.

Location

The mitigation is located in the area adjacent to Day Creek, city of Mira Loma, County of Riverside, 33 58 1.56 North, 1171 41 West


The original reason for berm construction was to prevent damage to the golf course as a result of floods from Day Creek. For eason, the berm will remain on the course, but will be revegetated with natives to discourage presence of invasives and allow eestablishment of native species. The area will also be protected from the public to prevent damage from debris and from offoad vehicles and horses in order to ensure proper species establishment.

Project: Riverside Flume PipelineLocation: City ofRiverside, County of RiversidePermit / Agreement # CDFG 1600-2007-0143-R6

Project Origin

The city of Riverside was required to mitigate for the .92 acres of temporary impacts to jurisdictional areas, including sparsely

egetated river bottom habitat. The impacts were a result of the replacement of the previously exposed Santa Ana River crosslume pipeline.


The city is required to perform onsite restoration in the project area consisting of replacing the moved sediment, as well as re-eeding the banks of the project area with native seed. Public access to the restoration site will be restricted, as will the activitllowed at the site. These restoration efforts will be documented by the city of Riverside in an annual report to the Departmen

Fish and Game that will be submitted for three years following the project. The city is also required to mitigate off-site byerforming restoration work in Santa Ana River Wooly Star (Eriastrum densifolium sanctorum) habitat at a 1:1 ratio within th

watershed.

Location

The mitigation will be placed within the Santa Ana watershed, near to the project site which is located at approximately 34 3.7 North, 117 19 47 West.


This mitigation has two goals stemming from the impacts to the streambed and banks of the immediate project area. The firstbjective is to restore the project site, including replacing sediment that was moved during the course of construction, as well aevegetate banks of the Santa Ana River to encourage restoration of native habitat. The second goal is to ensure no net loss ofuitable habitat for the Santa Ana River wooly star (Eriastrum densifolium sanctorum), a Federal and State endangered specieshat occurs along the banks of the Santa Ana River. The city of Riverside will restore .92 acres of such habitat within the

watershed, the location of which will be determined by the Inland Empire Resource Conservation District.

Project Origin

SunCal Companies was required to mitigate for the construction of tentative tract map 31462, in which 3300 residential units w

onstructed over the course of a four-phase process. This development resulted in 2.035 acres of permanent impact tourisdictional waters including mulefat/willow/cottonwood riparian and freshwater marsh habitat and 2.022 acres of temporarympacts to jurisdictional waters including riparian vegetation. In the course of the construction, best management practices faind foreign materials as well as mud and silt was allowed to pollute the waterway, resulting in additional mitigation.


The mitigation consists of creation of a 4.9 acre wetland drainage consisting of 2.2 acres of freshwater marsh and southern wilcrub habitat, and 2.7 acres of riparian woodland. This habitat has been planted, and will be irrigated through the end of its secear in existence; at the end of the fifth year, pending approval from the Department of Fish and Game, a conservation easeme

will be recorded in favor of the IERCD. The IERCD will also record an easement over the 11.1 acre existing wetland that wasdded to the mitigation requirements as a penalty for the violations that occurred during the construction process.

LocationThe 4.9 acre created wetland is located within the SunCal development among the residential units; the 11.1 acre unit lies to thast of the development, across Palmer Ave, adjacent to the golf 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 the construction of tract map 31462.Habitat loss, particularly what is classified as wetland habitat, can cause changes in migratory patterns of birds, in local climat

atterns, and in the make-up of plant and animal populations; for these reasons, it is imperative that wetland acreages destroyeltered during the course of development be repaired or re-created elsewhere. The 4.9 acre created wetland was planned andmplemented for this purpose. The additionf the 11.1 acre wetland to be conserved in

erpetuity was a result of a violation by thedeveloper.

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 facility consisting of 92,712 paved fee

torage, as well as a managers residence and a 46 space recreational vehicle storage area. In order to construct the storageacility, the developer will permanently impact .03 acres of an ephemeral drainage, which is a portion of a tributary to San

Timoteo Creek.

Required MitigationThis is a unique mitigation in that the developer is required to record a conservation easement over a 3 acre parcel of landncompassing an ephemeral drainage; however, there is no endowment because the amount of acreage impacted is so small. Tasement holds the IERCD responsible for protection of the drainage in perpetuity.

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

Purpose/Goal of the MitigationThe goal of the mitigation is to holdhe developer responsible forrojected permanent impacts to thephemeral drainage. The purpose ofecording the easement is to ensurerotection for the drainage inerpetuity, as well as the addition tonother piece of the wildlife corridorhe IERCD is attempting to constructetween Norton Younglove and the

Sunlite development.
