My sense was that the answer is "no," but I would like to confirm. It would be worthwhile to identify "dependent" questions in the guide (that is, the ones that can be skipped based on an answer to a previous one).
Rockingham Planning

Hello Everyone. At the training yesterday some people had expressed interest in seeing the text of our community notification letter. We keep a stack of these in our field vehicle and hand them out to members of the public when they inquire with our field crews. We found this beneficial to (1) provide them additional information and (2) avoid some of those long conversations we can get trapped in. ------------------------------------------------------------------------------ Memo To: RPC Commission Community Members and Municipal Officials and Staff From: Christian Matthews, Transportation/GIS Analyst, Rockingham Planning Commission Date: May 22, 2019 Subject: RPC Regional Stream Crossing Assessment Notification This summer and fall, Rockingham Planning Commission (RPC) is continuing a regional project aimed at identifying stream crossings (culverts and bridges) that may pose a hazard to our communities. This multi-year assessment of stream crossings in the region is intended to assist municipalities in identifying critical and hazardous culverts and bridges, particularly those susceptible to failure due to flooding or those that cut off critical evacuation routes. Using state stream crossing assessment protocol, RPC will have staff members out collecting data on state and local roads. The assessments will involve staff accessing crossings from public right of ways. The RPC shares all information collected with our member communities and works with those communities during the summer to help identify areas know to be problematic. Municipalities can use this information as a guide to prioritize those stream crossings most in need of retrofit or replacement. Along with prioritizing infrastructure modifications, results of these assessments can also be incorporated into municipal and regional hazard mitigation plans and vulnerability assessments. For more information about this project and to view this public data, please go to: http://www.rpc-nh.org/maps-and-data/data/transportation-asset-inventory-data For any questions or comments please contact Christian Matthews at (603) 658-0523 or cmatthews@rpc-nh.gov .
A hydraulic control is typically only defined, or found, in relation to the formation or presence of a pool. In other words, you are unlikely to have a true hydraulic control (that creates a continuous, flat water surface elevation) without having a pool. If you have a pool, a hydraulic control is likely present, but it may be hard to determine the control type - cobble or boulders are easy to visually assess, but if a streambed consists mostly of sand and gravel while curving gently upwards at the end of a pool, it can be considered a hydraulic control, though it is harder to identify.
Tom,
Based on your response here, when you say "if a streambed consists mostly of sand and gravel while curving gently upwards at the end of a pool, it can be considered a hydraulic control"--our question is, should the sand/gravel slope following a pool always be considered a hydraulic control? We have the opposite question of the original post: Can you have a pool without a hydraulic control? (when there is no cobble or boulder boundary (or other barrier type) at the end of the pool)
Hello,
Can you ask this on a separate post, and if possible, provide a photo?
Thanks,
Tom
