A new development is being proposed over a 10 acres site. The developer wants to divide the site into 40 lots and have a single-family home at each lot. Each home will take about 40 percent of the lot size. 30% of the lot will be landscaped with shrubs, the rest of the lot will be lawns and sidewalks. After finishing developing the site, the first rainfall of the season hits the development. The rainfall lasted for 3 hours with an average of 0.51 in/hr. Geotechnical report prepared as part of the city permit requirement showed that the initial infiltration was 0.32 in/hr, the final was 0.15in/hr, and decay constant was 0.1 Shr-1. Some residents complained that there was water accumulated at their properties cause some damages. Residents threatened to take legal action against the developer. The developer hired your company to investigate what had happen. You are assigned to the project and been asked by your supervisor to perform the following calculations: 1. What is the interception?
2. What is the infiltration?
3. In your opinion and based on your analysis do you believe that the residents allegations are founded?
