PROPOSED P~ ~: · TWenty-tive years

BACXGROtnm: The state, actinq by and through the state lands cmmdasion (SLC), acquired aoverei9Jl ownership interests in 172 acr• known as the Habitat Enhancement Parcel (•state Parcel•) pursuant to a Compromise Title Settlement .Agreement between the State, the City of San Leandra (City) and Citation Hemes, i.nc. (Citation). The State Parcel is described in J?xb:lbit •A•, attached hereto and incorporated herein by this reference. ol!'he State intereSts in the State Parcel-consist of ~overeign fee ownership ·af 144 acres and an easement for open space and habitat over 28 acres, fee title to which is in the City.

As part of the above-mentioned. title settlement agre~t .and past mitigation requirements placed an the City by the United

_States Army Corps of Engineers far dredging in the City's marina, :- ·the City is required to complete and maintain a Water Circulation

and Drainage Plan (Plan) far the State Parcel. The City is now ready to be9i.n illlpla:riaentatian of the plan and is requesting a lease from the SLC.

'!'be s~te ··i>arcel is geographically divided into three distinct portions, North Marsh, Bunker Marsh, and the East Marsh. . · Implementation of the City's Plan will resUlt in t!,le introduction of t·idal action to the State Parcel with the goal of recreating, to the maximum extent possible, the historic conditions which existed before levees isolated the marsb'1S fJ;'Qll tidal ~luence. seasonal, as well as tidal, wetland condi~ona for Jdgratinq and wintering resident shorebirds and waterfowl will be r•stored, or enhanced where al.ready present. 'l'be c:Onstruction of elevated refugial islands in the North Marsh is.des;gna4 to increase habitat of the endan9ered Salt Karsh Jlatv-~ llouaa. Work performed.in the area of the Bunker Kar8h will serve to further protect and enhance the Bunker Marsh and the unique sand dune area which exists south of the marsh. Abuse to the aensitive areas from off-trail activities, aw::h - motor biking, will be substantially curtailed when water is reintroduced to the marsh areas and public access is formally restricted.

The project will substantially improve existinq conditions on the sta1::e property and, thus, benefit th• aquatic ecosystems which exist at Roberts Landinq. The City's Circulation Plan was de~eloped with the cooperation of the United states Fish and Wildlife Service, california Department of Fish and Game, United States Army Corps of Engineers, and SLC starf.

The major features of the plan are: exC:avation and widening of the Roberts Landinq Slough from san Francisco Bay, at.the mouth of San Lorenzo creek, by dredging, generally following the path of the historic Roberts Landinq Slough, introducing tidal action to the BUpker and East Marsh: breachinq of the shoreline levee in the North Marsh by means of culverts within the levee. Five islands w9uld be created usin9 materials excavated from the slough and channels. construction deta~s are set forth in the Technical Jiiemorandum of ·construction Plan which are on file at . the State Lands Commission.

At its November 9, 1993 meeting, th.e Commission authorized a dredging lease to Citation Homes Inc. A portion of this project area involves land that the City has identified as a public

_...access.trail known as the "Loop" portion. The City has stated ·that the trail shown in the San Leandro Water Circulation and Drainage Plan Initial Study/Negative Declaration is proposed in the event that the Citation development project (and the associated central levee rem.oval and wetland restoration) is not implemented. If and when the Citation development is implemented, a permanent public access trail will be constructed

as provided for in the Citation development plan and as approved by the relevant responsible agencies.

A Mitigation Monitoring Plan was adopted by the City of San Leandro to ensure that mitigation measures described in the Negative Declaration are carriec! out •. · PerfDr11Bnce monitoring will be carried out for a·Jllini.Jaml of five years following construction in order to assess restoration progress and verify satisfaction of enhancement objectives. Monitoring reports will be prepared by the City of San Leandro or· their consultants and submitted to the United States Army Corps of Engineers on an annual basis with circulation to all agencies which .have jurisdiction, including the State Lands Commission. 'l'he City of San Leandro will be financially responsible for the long term maintenance work to be completed on-··the state ·parcel in regards to the water Circulation and Drainage Project..

The Commission has received a letter commenting on the City's Water circulation and Drainage Plan from the Ohlone Audubon Society, dated January 17, 1994. These comments have been addressed by Commission staff. other concerns raised in the letter are not within the jurisdiction of the SLC.

2, This activity involves lands which have NOT been identified as possessing significant environmental values pursuant to P.R.C. 6370, et seq, However, the commission has declared that all tide and submerged lands are "significant• by nature of their public ownership (as . opposed to •enviroJ111entally · · . sign~icant"). Sines such declaration of significance is not based upon the requirements and criteria of P.R.C. 6370, et seq., use classifications for such lands have not been designated. Therefore, the finding of the project's consistency with the use classification as required by 2 cal. Code Regs. 2954 is not applicable.

3. 'Any dredge spoils removed .f-rcm the state Parcel and not used for public health and safety purposes or for marsh restoration will have a mini.Jlnna charge of $.25 per cubic yard.

4. It is anticipated that the City will turn the long term management of the parcel over to the East Bay Regional Park District for on site management and enforcement purposes. Although the City will be responsible for costs ot long-term maintenance in relation to the Water circulation and Drainage Project.
