Hello, please understand I am a complete novice and a new pool owner. The damaged sod in the attached pic is the problem. We hired a nice fellow from a well known local landscaping company to propose a solution to the problem. The attached pic is the proposed solution. The yellow lines in the pic are 5" Wide, 6" deep channel drains. The green box is a 12" NDS Catch Basin connected to an underground pipe leading to a creek. The black lines are 4" Corrugated Drain Pipe . We have 2 questions.
Thanks in advance for you help,
Jeff

- Do the channel drains have to slope toward the catch basin? Can they be level with the pool desk? Of course they can't have a negative slope. That much I get.
- Is the sod around the black lines still susceptible to damage from water?
Thanks in advance for you help,
Jeff
