CalERBA Board President


Regional Director, Western Region, Westervelt Ecological Services


Hal Holland oversees the strategic and daily operations of Westervelt Ecological Service’s largest region in terms of projects, staff, and revenue. He is responsible for the development of mitigation and conservation projects, business development, sales, project compliance, and long-term land stewardship. In this role, Mr. Holland oversees a team of industry-leading experts in the realms of mitigation banking, land acquisition and valuation, ecology, habitat restoration and construction, regulatory permitting, and land management.

Prior to joining Westervelt, Mr. Holland worked for a leading mitigation banking firm as the conservation group leader, and also spent 5 years with EDAW, a national environmental consulting firm, as a project manager, biologist, and CEQA compliance specialist.

Partner, Mitchell Chadwick


Braiden’s clients include Fortune 500 companies with business interests in California, including commercial, residential, agricultural, and industrial businesses.  His representation regularly includes appearances before local, regional, state and federal administrative agencies in connection with use permits and other entitlements. He handles all aspects of environmental compliance under the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA), land-use permitting and any resulting litigation. His permitting work extends from California’s largest ski resorts, to residential developers, oil gas and energy companies, wineries, agricultural entities, landfills, mitigation/conservation banks, high-speed rail, and mining companies.

As one of the state’s most knowledgeable authorities on mitigation/conservation banking, Braiden is consistently on the faculty for legal and industry conferences on cutting-edge banking issues. The key to his success is working closely with the California Department of Fish and Wildlife, the U.S. Fish and Wildlife Service, and the Army Corps of Engineers to entitle mitigation banks throughout California.  This work is highly specialized, and includes in-depth title examination, negotiation with landowners, cities, Counties, and State and federal agencies to resolve conflicts with mineral rights, endangered species, jurisdictional waters, traditional land-use laws, and helping create crediting methodologies used by administrative agencies.  He understands both the regulatory risks as well as the business interests driving his client’s projects.  His professional working relationships with agency staff and counsel, as well as his unparalleled experience in this area of the law, makes Braiden uniquely suited to help his clients get their projects approved quickly and economically.

Sr. Principal Restoration Ecologist, Environmental Science Associates


Melissa Denena brings more than 20 years of experience wearing many different hats within the realm of the environmental consulting and operating field. In recent years, she has been solely focused on mitigation/ conservation banking and turnkey or PRM solutions. Melissa brings a unique understanding of the entire life of a mitigation project, including the real estate side of the equation, which means she can review a project’s mitigation needs and consult on the right location or avenue the client should take.


She applies her technical foundation and experience throughout the United States in wetland delineations, environmental impact assessments, regulatory permitting, and agency consultations, to develop and implement habitat restoration, enhancement, preservation, and adaptive management plans, and brings a wealth of experience in the technical design and real estate aspects of establishing conservation lands, both for voluntary and compensatory mitigation purposes.


Projects she leads entail planning the mitigation from start to finish which involves working closely with her clients, analyzing the mitigation solution options, scoping the chosen solution, and securing the various pieces of the solution from land, surveys, documentation, permits, restoration, easements, etc.  She also has direct experience leading major private and public mitigation and restoration opportunities for key clients in California and the Northwest.
