3.0 Trash management areas and control measures <br />This section describes the control measures that the City of San Leandro has or plans to <br />implement to solve trash problems and achieve a target of 100% (i.e. full) trash <br />reduction from their MS4 by July 1, 2022. The selection of control measures described in <br />this section is based on the City of San Leandro’s current understanding of trash <br />problems within its jurisdiction and the effectiveness of control measures designed to <br />reduce trash impacts associated with MS4 discharges. Information on the effectiveness of some trash control measures is currently lacking and therefore in the absence of this <br />information, the City based its selection of control measures on existing effectiveness information, their experience in implementing trash controls and knowledge of trash <br />problems, and costs of implementation. As knowledge is gained through the implementation of these control measures, the City may choose to refine their trash <br />control strategy described in this section. If significant revisions or amendments are made, a revised Long-Term Plan will be submitted to the Water Board through the City’s <br />annual reporting process. <br />3.1 Management Area Delineation and Prioritization <br />Consistent with the long-term plan framework, the City of San Leandro delineated and <br />prioritized trash management areas (TMAs) based on the geographical distribution of <br />trash generating areas, types of trash sources, and current or planned control measure <br />locations. TMAs are intended to form the management units by which trash control <br />measure implementation can be tracked and assessed for progress towards trash <br />reduction targets. Once delineated, TMAs were also prioritized for control measure implementation. The City of San Leandro’s primary management areas were selected <br />based on the spatial distribution of trash generating areas and the location of specific existing or planned management actions within City jurisdiction. City staff used the <br />following procedure to designate TMAs: <br />1. San Leandro consists of four main types of land use, a significant area of which is currently covered by full trash capture devices. These areas were used to generate the <br />basic outline for TMA’s. Areas designated with a “1” are those currently covered by full trash capture. Areas designated with a “2” tend to have high percentage of retail <br />properties. Areas designated with a “3” are comprised of industrial and commercial areas. Areas designated with a “4” are residential neighborhoods of various densities. <br /> 2. The four area types are then sectioned into sub-designations. Sub-designations are <br />used to indicate: Areas that are of the same land use type but separated <br />geographically; areas that are the same land use type with different population <br />densities; or, areas of the same land use type that will be better managed in smaller <br />sections. Sub-designations are noted by letter. <br /> <br />A map depicting the City’s TMAs is included as Figure 3-1. All jurisdictional areas within <br />the City are included within a TMA. The amount of jurisdictional land area and <br />associated trash condition categories for each TMA are included in Table 3-1. <br /> <br />335
