Description:
Abstract: This point dataset identifies all residential structures in the Cayuga Lake Watershed, and indiciates whether it is served by a municipal sewer system or is expected to have an on-site waste management system. TIGER Census 2000 data was used to estimate the number of individuals per residential structure.
Purpose: This geographic dataset was developed by the Cayuga Lake Watershed Network as part of a larger project, in conjunction with Dr. Douglas Haith and Cornell University, to model nutrient loading in the Cayuga Lake watershed. The model used is the Generalized Watershed Loading Function (Haith and Shoemaker, 1987). Haith, D.A. and L.L. Shoemaker, 1987. Generalized Watershed Loading Functions for Stream Flow Nutrients. Water Resources Bulletin, 23(3), pp. 471-478.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: The method for estimating the number of onsite wastewater management systems in the watershed involved first determining both the location of all residential structures and the extent of existing sewer districts, then identifying all the residential structures not located within the boundary of the sewer districts, assuming these residential structures would require onsite wastewater management systems. Though this method may not be precise, it is expected to provide reasonable and sufficient accuracy for estimating non-point source pollution at the scale of the watershed or subwatershed using the GWLF model. U.S. Census block-level data was used to estimate the number of residents per residential structure. The product of this effort was a single geospatial data layer indicating the location of all residential structures with onsite wastewater management systems and the estimated number of individuals using those systems. It is important to note that these numbers and locations are estimates and not precise measurements.
Logical_Consistency_Report: unknown
Completeness_Report: Includes all residential structures within the Cayuga Lake Watershed measuring over 700 square feet, as identified from aerial imagery captured in 2002 and 2003 in "leaf-off" conditions. The types of structures mapped included houses, mobile homes, apartment buildings, commercial buildings, government-owned buildings, churches, etc. The dataset did not include storage structures such as sheds or barns. The accuracy of this dataset was not assessed directly. However, given the very high level of detail in the aerial imagery, the accuracy of this dataset is expected to be quite high. It is unlikely that structures sufficiently large to be considered inhabitable (non-storage) would be undetectable by this visual analysis. Errors of omission are the most likely errors to be found in this dataset, which received a thorough analysis and review.

Process_Step:
Process_Description: Map location of all structures in the Cayuga Lake watershed: During the first phase of the study, the locations of all inhabitable structures were identified using aerial imagery acquired from the NYSDOP for Cayuga, Cortland, Schuyler, Seneca, Tioga, and Tompkins counties. The imagery was captured in 2002 and 2003 in "leaf-off" conditions. The types of structures mapped included houses, mobile homes, apartment buildings, commercial buildings, government-owned buildings, churches, etc. The dataset did not include storage structures such as sheds or barns.

Process_Step:
Process_Description: Classify structures as residential or non-residential: Each inhabitable structure was classified as residential or non-residential. The classification of each structure was based on the land use and cover type of the area in which it was located. The land use and cover geospatial dataset used to determine a structure's class was developed in the first phase of the development of the CLW GWLF GIS.

Process_Step:
Process_Description: Identify residential structures within the extent of the municipal sewer systems: Detailed information about which structures were connected to municipal sewer systems and which required on-site waste management systems was not available. Therefore, the simplest assumption, that all residential structures within a reasonable distance, 150 feet, of a sewer line are connected to that sewer system was chosen. Although this assumption might not be accurate in all cases, it should hold true in the majority of cases. All residential structures that met this assumption were classified as being on a municipal sewer line and therefore not having an on-site waste management system. All residential structures not identified as being on a municipal sewer system were classified as having on-site (septic) waste management systems.

Process_Description: Estimate number of residents per residential structure: To develop an estimate of the number of individual residents using each on-site waste management system, the total number of residents within each census block was divided among the residential structures located within that census block.
