FINANCIAL IMPACT None.. REASON EOR RECOMMENDATION/BACK RC OUND The McNabney Marsh is a wetland located in the Martinez area just east of Interstate 680 near the Marina Vista exit. It was formerly known as the Shell Marsh. Much of the marsh and the uplands which surround it were purchased with settlement funds from Shell Oil following a spill in the marsh. Primary landowners include the East Bay Regional Park, the Mountain View Sanitary District, and Caltrans. Funds from the oil spill settlement, from Caltrans, and other sources have also been used to improve the marsh hydrology, primarily through the installment of tide control gates in 1998 which will allow greater control of flows in and out of the marsh. The Fish and Wildlife Committee ("FWC") has been actively involved in issues related to McNabney Marsh for many years. The FWC has met on numerous occasions with representatives of organizations interested in the management of the marsh, and has also Al CONTINUED ON ATTACHMENT: X YES SIGNATURE; `�L omas K,'Studley G`hair, Fish'& Wildlife Committee RECOMMENDATION OF COUNTY ADMINISTRATOR RECOMMENDATION OF BOARD COMMITTEE APPROVE OTHER SIGNATURE(S): �1 } ACTION OF BOARD ON .,,�,%`�- �`` APPROVED AS RECOMMENDED OTHER VOTE OF SUPERVISORS 71 UNANIMOUS (ABSENT___,ZI HEREBY CERTIFY THAT THIS IS A TRUE AND AYES: NOES: CORRECT COPY OF AN ACTION TAKEN AND ABSENT: ABSTAIN: ENTERED ON THE MINUTES OF THE BOARD OF SUPERVISORS ON THE DATE SHOWN.

In 1997, based on a n9c0nlnnendadoO from the F\8/C, the Board of Supervisors sent a letter to the East Bay Regional Park District ("EBRPD") urging an examination of grazing practices to assure that waterfowl nesting is not hampered. The grazing issue continues to be discussed by the FVVC, EBRP[], and other organizations. E8RPD is now preparing a management plan for its lands, which include most of the upland areas and aportion ofthe wetlands. The FVVChas also discussed issues related tomarsh hydrology and the operation ofthe new tide gates. The Shell Management Advisory Committee, acommittee of agency and non-profit representatives, is finalizing a management plan for McNabney Marsh which focuses on hydrological issues and the operation ofthe tide gates. The FVVC recognizes that significant progress has been made to protect the marsh, but believes that better coordination among interested parties and between planning for the uplands and the wetlands is needed to continue to enhance this important resource. To this end, the FVVC Voted unanimously on April 31 to recommend that the Board of Supervisors send a letter to all organizations with an interest in the McNabney Marsh urging cooperative development of a management plan for the entire marsh complex. The recommended text of the letter and the list of agencies which should receive it is attached. Key points raised in the letter include the following: ° acknowledgment that significant prugnaea has been made todate ~ McNabney Marsh is one of the most visible and important wetlands in the County and therefore merits careful, effective management 0 management planning for the area is bifurcated, involving separate management plans for different landowners and different sections of the marsh (i.e. uplands and wetlands) * this "two track" approach may not besufficient to articulate overall management goals or provide for implementation of more complicated actions involving nnu\bp/e agencies w relocation of the Mountain View Sanitary District discharge location and grazing practices are two examples of issues that need to be addressed in a coordinated manner ° cooperative development of a comprehensive management plan for the entire McNabney Marsh complex is animportant next step inthe enhancement process and may help assure coordinated implementation bymultiple parties ATTACHMENTS: ° recommended text of letter on McNabney Marsh ° list of agencies to which the letter should be sant CiN1Yo0CU-1\jKDpC\JOHN'OLo\F&VVB0MCN.LET 114 The Board Supervisors Contra iP11e-Cf foe Boas and County Adrrlinistratson BuildingCosta Coun4y Ad^^iristralor 5` bins Street, Room 106 (925)335-1900 Pa srtinez, Caiiforr is 94553-'1293 County John Gioia, qct J{str°c Gayle B.

To sage paper, only one sample letter P.O. Box 5381 has been provided.) Oakland, CA 94605-0381 Re: McNabney Marsh Dear Mr. O'Brien. The Contra Costa County Board of Supervisors has authorized this letter to urge that all parties with an interest in the McNabney Marsh near Martinez work cooperatively to develop a comprehensive management plan for this important area. Such a plan is needed to enhance the natural resources of this highly visible wetland complex and assure that management is coordinated among different property owners and between both uplands and wetlands. This letter is being sent to your organization as well as others with an interest in the McNabney Marsh based on advice from the Contra Costa County Fish and Wildlife Committee, a committee appointed by the Board of Supervisors to provide information and advice on issues affecting the fish and wildlife resources of Contra Costa County. Since the Shell Oil spill in 1988, your organization and others have made substantial progress towards protecting the McNabney Marsh (then known. as the Shell Marsh). Key achievements include public acquisition of the marsh,removal of cattle from the wetlands proper, and construction of the tide gates to increase management capabilities. Continuing this forward progress is crucial. McNabney Marsh is the most visible wetland in the County, located directly adjacent to Interstate 680 and in plain view of the tens of thousands of people who use that freeway every day. Likewise, Mc'-N'abney Marsh is exceptional because it supports an extremely diverse array of species,because large seasonal wetlands, especially those which retain some surrounding upland habitat, are rare in this area, and because the unique qualities of the marsh make it a valuable place for education. Developing a comprehensive management plan for the McNabney Marsh complex is a critical prerequisite to further enhancement. The McNabney Marsh Management Advisory Committee (MAC) is finalizing a management plan focused on hydrological aspects of the?Marsh and the new Mr. Pat O'Brien May 25, 1999 Page 2 of 2 tide gates. Likewise, the East Bay Regional Park District apparently has begun work on a management plan for the upland areas it owns. However, no mechanism is in place to articulate broad management goals for the entire complex and integrate the actions of different agencies in different areas. For example, relocating the Mt. View Sanitary District discharge location to the southern end of the marsh may be an effective means to improve diversity in the marsh by creating a definite spectrum of habitats within the complex,providing freshwater marsh habitat in some areas and more brackish habitats in other areas. This concept has been discussed by many of the agencies involved with the marsh, but because studying and implementing this proposal will involve close coordination of multiple landowners throughout the area,it is unlikely that the"two trach"approach to management planning can even identify relocation of discharge as an issue, not to mention plan for further analysis and implementation. Grazing is another issue which will require close coordination among agencies and between different sections of the marsh complex. The location, timing, and intensity of grazing relates not just to the uplands, but may also effect broader, system-wide processes such as sedimentation, waterfowl nesting, and water quality. Grazing may also occasionally be necessary on the fringes of the wetlands themselves. An adaptive, comprehensive planning approach is needed to determine if current wetland setbacks are adequate, if grazing intensity and timing can be altered to improve overall resource value, and if exclosures should be constructed around swabs and other areas. Separate, uncoordinated plans are not sufficient for addressing these types of issues. The management challenges associated with McNIabney Marsh are complicated, but they can be effectively addressed if the involved organizations can work cooperatively and manage the marsh system as a whole. Cooperative development of a comprehensive management plan may form the basis for successful interagency management of the marsh in the future,and is an important next step toward significantly enhancing McNabney Marsh.

Likewise, McNabney Marsh is exceptional because it supports an extremely diverse array of species, because large seasonal wetlands, especially those which retain some surrounding upland habitat, are'rare in this area, and because the unique qualities of the marsh make it a valuable place for education. Developing a comprehensive management plan for the McNabney Marsh complex is a critical prerequisite to further enhancement.

Likewise, the East Bay Regional Park District apparently has begun work on a Mr.Pat O'Brien May 25, 1999 Page 2 of 2 management plan for the upland areas it owns. However, no mechanism is in place to articulate broad management goals for the entire complex and integrate the actions of different agencies in different areas. For example, relocating the Mt. View Sanitary District discharge location to the southern end of the marsh may be an effective means to improve diversity in the marsh by creating a definite spectrum ofhabitats within the complex, providing freshwater marsh habitat in some areas and more brackish habitats in other areas, This concept has been discussed by many of the agencies involved with the marsh, but because studying and implementing this proposal will involve close coordination of multiple landowners throughout the area, it is unlikely that the"two track" approach to management planning can even identify relocation of discharge as an issue, not to mention plan for further analysis and implementation. Grazing is another issue which will require close coordination among agencies and between different sections of the marsh complex. The location, timing, and intensity of grazing relates not just to the uplands, but may.also effect broader, system-wide processes such as sedimentation, waterfowl nesting, and water quality. Grazing may also occasionally be necessary on the fringes of the wetlands themselves. An adaptive, comprehensive planning approach is needed to determine if current wetland setbacks are adequate, if grazing intensity and timing can be altered to improve overall resource value, and if exclosures should be constructed around swales and other areas. Separate, uncoordinated plans are not sufficient for addressing these types of issues. The management challenges associated with McNabney Marsh are complicated, but they can be effectively addressed if the involved organizations can work cooperatively and manage the marsh system as a whole. Cooperative development of a comprehensive management plan may form the basis for successful interagency management of the marsh in the future, and is an important next step toward significantly enhancing McNabney Marsh.
