> Hunting or trapping prohibition (except for research and limited rodent and feral animal control). > The use of all terrain vehicles,motorcycles, or other motorized vehicles off of roads or travel ways will be restricted. Electric powered boats will be permitted on the lakes, but no jet skis or other petroleum-fueledengines will be allowed. c) Homeowners'Association and Design Review Board A Homeowner's Association will be formed to administerthe maintenance program for the open space, common areas, private streets and access easements.It is anticipated that the natural areas will be jointly administered by the homeowner's administration and a nature group. The nature group will also have input into management practices outside the natural zone which influence the natural zone. Under the auspices of the association, a design review board, consisting of the chairperson and an architect,will review and approve the exterior design of all new construction and remodeling projects. Tracy Lakes consists of two lakes, both totaling approximately 350 acres in size. Historically,these lakes would fill with water by early winter and become dry by mid summer. Human impact to waterfowl populations will vary in relation to the placement of houses, golfing activities. Bird tolerance to human activities varies with species and individuals. Some species are more tolerant to the presenceof humansthan others. And individualswithin a speciesvary; thus an individualmay become acclimated to the presence of humans over time,whereas a newly arrived migrant may be extremelywary of human presence. An important consideration in human/wildlife interactions is the predictability of human presence. When humans burst upon wildlife in isolated areas, they usually flee quickly. Many species of wildlifecan become accustomedto the presenceof humanswhen theirpresenceis regularand predictable. Thus wood ducks are easily frightenedin isolated wetlands,but can become accustomedto humans in city parks. It is predicted that species of waterfowl will sort themselves out at Tracy Lakes. Flighty species and individuals will likely utilize the east end of South Tracy lake. Other species, especially over time, will become accustomed to humans at the west end of Tracy Lake and North Tracy Lake. Specific mitigation measures to reduce human impact on the lakes include: > Planting riparian trees along the fringes of the lake, especially in the spaces between houses. This vegetation will provide screening to lessen the impact of human presence. This acreage is not included in the previous estimate of 50 acres of riparian habitat restoration. > The construction of a 50 - 100 ft. elevated bench at approximately two feet below the water surface. The growth of cattails and bulrush will provide screening,nesting,resting,foraging,and escape cover. > Restrictions on pets. > Conservation easementshall include language that states electric powered boats will be permitted on the lakes, but no jet skis or other petroleum-fueledengineswill be allowed. H. BIOLOGICAL RESOURCES H-1. Potentially Significant Impact: Loss and disruption of nesting and foraging habitat for the Swainson's hawk. (EIR 4.7-1) Developmentwill result in the loss of critical nesting habitat and foraging habitat for the state-threatened Swainson's hawk. Two active nest sites were identified by the EIR 3
