IH35, Suite 100 <br /> Austin, Texas 78704 <br /> RE: San Marcos River Corridor Plan <br /> Texas Recreational Trails Fund Required Review <br /> Dear Information System Manager: <br /> We are requesting your standard computer and map search for our project. We have <br /> applied to the Texas Recreational Trails Fund to add approximately 5,300 lineal feet of trails <br /> for hike, bike, walking and jogging. Trail construction will affect approximately 1.9 acres of <br /> and will involve blading, grading, surfacing of an 8' wide decomposed granite trail. <br /> Vegetation will be pruned back to 4' on each side of the trail edge, and gTound cover mowed <br /> within this area. A single crossing at the Purgatory Creek, which is an intermittent stream <br /> is proposed. The site for the proposed trail is public land owned and opertated as a park <br /> by our city. <br /> The soils at the site have been identified by the Soil Conservation Service as Oakalla soil <br /> and Oakalla Silty Clay Loam. The vegetation communities are varied in type and include <br /> all types of vegetation common from stream beds to upland. Along the river, large cypress <br /> is the dominatant tree. At higher elevations oaks and elms of various types are the <br /> dominant tree cover. Hackberries of all sizes are interspersed among the other trees. It is <br /> estimated that the canopy cover of aU the trees within the 110 acre site covers no less than <br /> 50% of the area. Except for the cypress trees along the river edge, all other tree species are <br /> . approximately evenly distributed. <br /> Except for 310 lineal feet of trail over 'wetlands'" the vegetation communities for the land <br /> . adjacent to the, trail corridor is predominantly grass. The trails are being placed where the <br /> park patrons have denuded the grass cover by constant use. These areas are not located <br /> within any fragile vegetation, or if near it that vegetation has already been impacted. The <br /> wetland vegetation consists primarily of "elephant ears". A raised trail to protect the wetland <br /> form park patrons will be constructed. Only the vegetation directly under the trail will be <br /> impacted. <br /> City Hall. 630 East Hopkins.
