Rio Vista Park: GPS Inventory & Land Management Brian Singer Amy Cogdill John Elkins Chris Rollins

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) CTGC 2 2/25/2015

Scope CTGC 3 2/25/2015

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 CTGC 4 2/25/2015

Minimize & Mitigate • Porous Concrete/Asphalt • Transformation of impervious cover • Mulch • Vegetation and rainwater • Crushed rock collection CTGC 5 2/25/2015

Data • Most of the data for this assignment will be collected in situ by CTGC, using a Trimble Geo. XT GPS unit • Park boundaries, river boundaries, GPS monuments for reference and the City’s own Land Development Code can all be downloaded from the City’s page • Central Area Council of Governments, USGS and Ebsco CTGC 6 2/25/2015

Software • Adobe Photoshop & Illustrator • Microsoft Excel, Power. Point and Word • Arc. MAP, Pathfinder, ERDAS Imagine and Arc. GIS Online CTGC 7 2/25/2015

Timeline • Phase I Data Collection • Six Weeks • Phase II Data Processing and Analysis • Four Weeks • Phase III Editing, Revision, Document Production • Two Weeks CTGC 8 2/25/2015

Methodology CTGC • 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 • Investigate the spatial attributes of existing IC • Test collection of single feature class, points, lines, polygons • Research different options for mitigating IC • Revise database, adding and subtracting features • • Finish feature collection • 9 Merge our data dictionary with other group Begin analysis for the mitigation of impervious cover Measure existing impervious cover Propose changes to IC, and model with maps 2/25/2015

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 CTGC 10 2/25/2015
