Create a detailed coloring page illustration of an earthwork construction site with a trench excavated for cable installation. The scene should show the rugged, uneven terrain of the trench, surrounded by houses and trees on both sides. Include intricate line work to emphasize the soil textures in the trench, the structure of the nearby houses, and the foliage of the trees. The style should resemble realistic architectural line art, focusing solely on clean, sharp lines suitable for coloring, with no shading or color --ar 70:99
