Make the landscape plan work with the drainage map.
San Marcos offers property-level floodplain information covering local drainage, floodways and historical flooding. For a landscape refresh, establish which parts of the site are appropriate for planting, gathering and circulation before deciding where to add beds or change grades. A planted border should support the way water leaves the property, not hide a recurring problem.
Bring a survey, rainfall photos and any previous drainage work records. We can separate appearance improvements from earthwork that needs further review. On an occupied commercial site, identify entrances to keep open; at a home, identify the views and established trees that should remain the anchors of the renovation.
