SAN MARCOS DRAINAGE MASTER PLAN

SCHEMA FOR APPENDICES B, C, D AND F

INTRODUCTION
The classification of junctions displayed in the legend of the Appendices B, C, D and F are per the field Structure Type Description from the existing inventory SD_StructureNode provided by the City of San Marcos as a part of the City of San Marcos Drainage Master Plan.

The classification of conduits (storm drain conveyance) displayed in the legend of the Appendices B, C, D and F are per the field Conduit type from the existing inventory SD_Main and SD_Channel provided by the City of San Marcos as a part of the City of San Marcos Drainage Master Plan.

SCHEMA
Junctions
Channel Confluence: Junctions that are used to split the channel into multiple reaches Cleanout: A stormwater-specific facility that is used as an opening in a collection system for inserting tools, rods, or snakes while cleaning a pipeline or clearing a stoppage. It is also known as a manhole.

Curb Inlet: An opening in the curb of a roadway to convey storm water to a connected storm drain system.

Curb Outlet: An opening in the curb of a roadway to convey storm water to the adjacent roadway.

Detention Basin: Surface or sub surface storage basins or facilities that provide flow control through attenuation of stormwater runoff.

Inlet: An opening to convey storm water to the connected storm drain system.

Outlet: An opening in the curb of a roadway to convey storm water to the adjacent roadway.

Other: Unknown structure, Includes junctions from the original inventory which are not categorized.

Separator: a structure that separates storm water into its constituent or distinct elements.

Outfalls: A discharge point of storm drain into a body of water.

J#17729
San Marcos Drainage Master Plan
Conduits
Culvert: A structure that allows water to flow under a road, railroad, trail, or similar obstruction from one side to the other side. They include arch culverts, box culverts and pipe culverts.

Channel wider than 5 ft: This includes channels conveying storm water with bottom width greater than 5 feet.

Ditch wider than 5 ft: A ditch constructed to intercept and convey minor surface drainage runoff with bottom width greater than 5 feet.

Elliptical: Storm drain pipes with an elliptical cross-section.

Natural Channel: Includes natural conveyance channels and ditches.

Storm Main: Includes storm drains with varying shapes and materials.

Flowline: Includes connections required to have a hydraulically connected system.
