| Aquatic Park, City of Berkeley |
|
LMA served as the prime contractor to complete a natural resources plan for this shoreline lagoon that suffers from poor water quality and low levels of wetland habitat. The goal of the project was to create habitats while addressing recreational uses and contaminants in stormwater runoff. LMA digitally mapped the wetlands, invasive plants, lagoon depths, recreational uses and other features and worked in conjunction with an engineering firm to evaluate changes in lagoon hydrology to improve water quality and allow for habitat restoration. The project involved an oversight committee of City staff and residents. |

| Atascadero/Green Valley Watershed Assessment, Sonoma County |
|
LMA worked with a local watershed council to evaluate natural features and land uses in the Atascadero and Green Valley Creeks watershed. Roads, impervious surfaces, urban areas, vineyards and other land uses were delineated on a digital aerial photograph base. Geology, water resources, riparian habitat, characteristics of creeks, groundwater and other watershed features were researched and documented. Recommendations for restoration and watershed improvements were included. |

| Buena Vista Lagoon Watershed Restoration, San Diego County |
| This watershed in San Diego County was rapidly urbanizing, thereby increasing impervious cover and changing the volume and timing of stormwater flows. The watershed plan focused on installation of stormwater detention facilities, erosion control at construction sites and a design for fully vegetated flood control channels. The program integrated wetland and watershed restoration. |

| Copeland Creek Watershed Assessment and Enhancement Plan, Sonoma County |
| Watershed and stream conditions in 1942, 1961, 1980 and 2000 were delineated and compared to quantify changes in the watershed using a GIS (Geographic Information System). The stream system of this watershed was evaluated and the riparian corridor and erosion sites were mapped. Field monitoring and evaluation of channel form, bed composition, siltation, riparian habitat, watershed vegetation and water temperatures were completed. Recommendations for riparian restoration and sediment reduction projects were included. |

| Feasibility Study for the Mare Island Dredged Material Ponds |
| LMA contributed to a feasibility study of the City of Vallejo taking over the operation of a series of dredged material disposal ponds on the closed Mare Island Naval Shipyard. LMA conducted the analysis of maintenance dredging projects, both federal and private, which might use the ponds and the permitting and environmental requirements. This analysis included the frequency, location and quantities of dredging, as well as the costs. The financial feasibility of operating the sites as a business was also evaluated including the resale market (landfill cover, construction materials) for the dredged material. |

| Feasibility Study for the Re-handling of Dredged Material in San Francisco Bay |
| LMA was the prime consultant overseeing a team of five consultants for the Port of Oakland. Working with a committee of five regulatory agencies, ports, environmental groups and businesses interests, LMA evaluated five sites for the development of a rehandling facility for material dredged from the bay. Re-handling uses evaluated included sand and gravel, landfills and construction projects. Engineering, environmental and economic features of each site and potential benefits and drawbacks of operating each site for re-handling were documented. |
