WCP provides professional planning services for a variety of clientele including architecture, engineering, and other planning firms; land developers; private industry clients; and government agencies at the local, state, and federal levels. WCP's planning services are wide-ranging and include site assessment and selection studies, conceptual and master plans, feasibility studies, space analyses, land use and environmental permitting, environmental impact review, and more.  
WCP has extensive experience in preparing both NEPA- and HEPA-compliant environmental assessments and environmental impact statements. WCP began providing EA/EIS services for projects in Hawaii beginning in 1979 under the newly adopted HRS Chapter 343 and its implementing regulations in Hawaii Administrative Rules Title 11, Chapter 200. In the Pacific region, we have completed NEPA-compliant EAs/EISs for the U.S. Army Corps of Engineers and Naval Facilities Engineering Command addressing actions in Hawaii and U.S. territories and protectorates many of which have addressed diverse, complex, and oftentimes challenging actions such as the Palau Compact Road EIS (1999), two EAs for the U.S. Agency for International Development (USAID)-sponsored Post 2004 Tsunami Banda Aceh to Meulaboh Road Reconstruction and Rehabilitation (2007), and the Apra Harbor Improvements EIS (2009).

Due to a change in project site, as well as the long-term vision of the UHCWH, including expanded educational offerings and integration with the adjacent Palamanui master-planned community, WCP was tasked with preparing an update to the existing 2001 LRDP.  In conjunction with the updated LRDP, WCP also completed a Supplemental EIS, and conducted a Phase I Environmental Site Assessment (ESA) for the new project site. Due to the known presence of Native Hawaiian burials in lava tubes located at the site, the project also included preparation of a Burial Treatment Plan that was approved by the Hawaii Island Burial Council and the State Historic Preservation Division.  WCP has been involved in the planning of the new UHCWH for many years beginning with a site selection/site assessment study in 1991. WCP then completed the 1998 LRDP and the 2000 EIS for the UHCWH project.  UHCWH is now called Hawaii Community College Palamanui and opened in Fall 2015.


WCP was tasked with identifying the space requirements and guidelines for implementing a lower school program at Saint Louis School. WCP also identified potential sites within the Saint Louis School campus and evaluated its suitability as the location for the proposed lower school. Potential sites were evaluated against a set of general requirements such as size, safety and security, access, infrastructure, current use, and surrounding uses. Site-specific layout options were developed to illustrate the amount of land required to accommodate the lower school facilities. Study outcomes assisted the Saint Louis School administration and board of trustees in determining whether the school had sufficient land and facilities to adequately develop a complete lower school, and enabled them to establish an academic policy on grade level offerings.


The Koolau Greenbelt & Heritage Trails System was one of the City and County of Honolulu's Vision Team projects, a program developed to involve the public directly in the planning of their respective communities. WCP worked closely with a Vision Champion from the windward Oahu community. As part of the planning process, WCP consulted with community members, neighborhood boards, and various city and state agencies to define project requirements. WCP also conducted background research on site constraints, access routes, existing facilities, natural features, land ownership, and permitting requirements. The trails system was envisioned as a series of multi-use pathways and trails for hiking, biking, riding, hunting, and other recreational activities along the base of Oahu’s windward cliffs. Trail sites were chosen by the community, based on cultural, historical and natural significance. WCP prepared a conceptual planning document to summarize these initial planning efforts.


WCP was tasked with preparing several SMA assessments for Kahului Trucking and Storage (KT&S) to address proposed improvements at its Kahului facility which is within the Maui County’s coastal SMA. Proposed improvements included repair of an aboveground storage tank used for molasses produced by Hawaiian Commercial & Sugar Company’s Puunene factory, additional on-site molasses storage, and repair and maintenance of the KT&S roundhouse machine shop building.  The SMA assessments were prepared in accordance with the objectives and policies of HRS Chapter 205A (Coastal Zone Managment) and Maui County's Special Management Area rules.



The Geary property was once occupied by a single-family residence destroyed by fire. Vestiges of the previous residential occupation include a long unpaved driveway and approximately 3.5 acres of previously cleared land. Except for the cleared areas, the parcel is mostly covered by lowland forests of introduced tree species. The current owner wanted to plant a variety of native grasses, fruits, vegetables, flowers, shrubs, and trees, and to care for a small number of domestic animals on the property.  WCP prepared a site master plan and evaluated site alternatives for terracing to create additional planting space on the steeply-sloped property, and to determine appropriate-sized pasture, shelter, and support for a small number of proposed domestic animals. WCP prepared the EA and Conservation District Use application for the property, both of which were approved.



In 2010, the U.S. Army Corps of Engineers released the results of a study modeling existing flood conditions along Moanalua and Kahauiki Streams located near Fort Shafter Flats. The study used current topographic and bridge-modeling software to update floodplain information from the 1970s and 1980s that was generated using older software. The updated models documented the need for new flood mitigation measures that will include constructing a levee along the east bank of Kahauiki Stream and new stormwater detention facilities. Bridges must also be modified, underground storm drainage lines relocated, and a new drainage pump station and a generator building will be built.  WCP prepared an EA to ensure that comprehensive and systematic consideration was given to the potential environmental impacts of the proposed floodplain management measures.



WCP prepared an EIS for implementation of the DOT Harbors Division’s 2020 Master Plan that addressed development of Oahu’s commercial harbors.  The Master Plan included long-range plans for Honolulu, Kewalo Basin, and Barber’s Point to be capable of meeting the needs of the State’s growing economy through the year 2020; ensured optimal utilization of land and water resources to support marine cargo, passenger transport, and fishing operations; and that harbor facilities would be developed in a safe, secure and efficient manner.  The EIS assessed project improvements contained in the Master Plan including construction of passenger vessel terminals; new paved roadways; parking; demolition of some existing facilities; an extension of Punchbowl Street; and installation and/or upgrading of lighting, curbing, drainage, sewers, signage, landscaping, water supply, and signalized intersections.
