Sign Code Authority
Chapter 11, Signs, of the Lewisville Code of Ordinances — permissible signs requiring a permit set out in Article IX, section 11-10; administered by Building Services, with a Unified Development Code and zoning district standards applying alongside
Shared Sign Area Pool
Total allowable square footage may be used as wall signs, or may be used as roof and low profile monument signs with a corresponding reduction of wall signage — adding a monument reduces what the building can carry
Monument Placement Rule
The low profile monument sign must be placed on the side of the building from which it draws its allowable square footage
Wall Sign Height Ceiling
No wall sign may project above the highest point of the building, excluding rooftop mechanical structures, chimneys, elevator shafts, ventilators, and similar facilities — often the binding constraint on low-parapet retail and flex buildings
Reader Board — Existing Sites
On an existing site with freestanding signage, a low profile variable message electronic reader board monument is allowed provided an existing freestanding sign is removed from the site — a one-for-one replacement
Reader Board — New Sites
On a new site, or an existing site with no freestanding signs present, a low profile variable message reader board monument is allowed — but no freestanding signs will then be permitted on the site
Reader Board Display Standards
Variable message electronic reader boards may not be animated, flash, or scroll, and must remain static for not less than 7 seconds
Reader Board Character Height
Sign characters must be a minimum of 4 inches and a maximum of 10 inches tall — an unusual ceiling that directly limits copy length and legibility range
Hanging Signs
Allowed in all commercial zones, designed for installation under an awning or canopy above the sidewalk; may not be installed, constructed, or erected prior to the issuance of a sign permit
Suburban Coverage
Flower Mound, The Colony, Carrollton, Coppell, Highland Village, Corinth, Denton, Frisco, Grapevine
Wind-Load Standard
115 mph ultimate design wind speed, Risk Category II — with additional foundation margin considered on properties carrying open-water exposure near Lake Lewisville
Severe Weather Considerations
Active severe-hail corridor — impact-resistant polycarbonate faces, reinforced retainers, and sealed cabinets specified as standard; straight-line wind and tornado-region foundation anchoring; 100°F-plus summer thermal load on drivers and power supplies
Highway Frontage
I-35E, SH 121 Sam Rayburn Tollway, SH 121 Business, FM 407, FM 3040 Round Grove Road, plus the Main Street, Josey, and Valley Parkway arterials — TxDOT permit required separately for signage visible from the state highway system
