The City of Diamond Bar is seeking proposals from environmental consulting firms to prepare the appropriate CEQA document to assess the potential environmental impacts associated with proposed improvements to a 1.29 linear mile established pedestrian trail, and to identify appropriate mitigation measures to avoid or reduce those impacts to less-than-significant levels. The requested scope set forth in this RFP includes the preparation of a biological resource assessment report, as well as attendance at public meetings and hearings.Staff believes that an Initial Study will likely conclude that a Mitigated Negative Declaration is the appropriate environmental determination for this project, and the requested scope reflects this assumption. Should it subsequently be found that an EIR will be required, the City will request an amended scope of work.
