Rio Vista Park: GPS Inventory & Land Management Brian SingerJohn Elkins Amy CogdillChris 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) 2/25/20152CTGC

Scope 2/25/20153CTGC

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 2/25/20154CTGC

Minimize & Mitigate Porous Concrete/Asphalt Mulch Crushed rock Transformation of impervious cover Vegetation and rainwater collection 2/25/20155CTGC

Data Most of the data for this assignment will be collected in situ by CTGC, using a Trimble GeoXT 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 2/25/20156CTGC

Software Adobe Photoshop & Illustrator Microsoft Excel, PowerPoint and Word ArcMAP, Pathfinder, ERDAS Imagine and ArcGIS Online 2/25/20157CTGC

Timeline Phase I Data Collection Six Weeks Phase II Data Processing and Analysis Four Weeks Phase III Editing, Revision, Document Production Two Weeks 2/25/20158CTGC

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 2/25/20159CTGC

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 2/25/201510CTGC
