Introduction
• Central Texas Geospatial Consulting is working with the City of San Marcos to create an inventory of Rio Vista park features
• Further research will be done to solve the issue of impervious coverage in the park
• Impervious Cover - “concrete or asphalt, they can be roofs or parking lots, but they all have at least one thing in common – water runs off of them, not through them” (Frazer 2005)
• Potential Harm – “Impervious surfaces collect automobile contaminants, phosphates from residential and agricultural fertilizers, and dozens of other pollutants” (Frazer 2005)

Purpose
• The City of San Marcos needs a digital inventory of their parks and green spaces• Construct a user-friendly inventory of
park and green space features
• Provide suggestions to eliminate some of the negative outcomes from the impervious coverage around the park• Helping the ecosystem of the river

Methodology
• Collect initial data from client and other sources
• Compile list of known features
• Collaborate with other City of San Marcos group
• Add feature list to database
• Test collection of single feature class, points, lines, polygons
• Revise database, adding and subtracting features
• Finish feature collection
• Merge our data dictionary with other group
• Begin analysis for the mitigation of impervious cover
• Measure existing impervious cover
• Investigate the spatial attributes of existing IC
• Research different options for mitigating IC
• Propose changes to IC, and model with maps

Methodology
• Begin post processing of the data with emphasis on making the database as user friendly as possible
• Transfer GPS data into database
• Finally, assemble the following deliverables: amenity geodatabase, map of the park with feature classes, report and visual model of proposed changes to the IC
