Hi,
Sorry to be getting these questions to you so late - it's been an insane week!
1. At the discretion of the City Engineer, a TAL may satisfy the City’s transportation analysis requirements, in lieu of a TIA, when a development meets all of the following criteria:
If we don't have a city engineer on staff, who makes the decision about accepting a TAL rather than a TIA?
2. Under the same section bullet point 4 in this section:
When specific criteria generally associated with small developments are met, a Transportation Analysis Letter (TAL) may be substituted for the required TIA. At the discretion of the City Engineer, a TAL may satisfy the City’s transportation analysis requirements, in lieu of a TIA, when a development meets all of the following criteria:
1 . The development generates fewer than 25 peak hour trips during either the AM or PM peak hour. (Two examples of common developments generating fewer trips than these threshold levels are: a subdivision containing 25 or fewer single-family residences or a general office building less than 15,000 square feet.)
2. The development is not expected to impact intersections that currently fail to meet the City’s level of service standards or intersections that are operating near the limits of the acceptable level of service thresholds during a peak operating hour.
3. The development is not expected to significantly impact adjacent roadways and intersections that are high accident locations, areas that contain an identified safety concern, or high concentration of pedestrians or bicyclists such as school zones
4. The development generates an increase in use of adjacent streets by vehicles exceeding the 20,000 pound gross vehicle weights by less than 10 vehicles per day;
1-3 seem to address creating boundaries on significant impacts or establish lower thresholds of impact. #4 addresses an INCREASE in impact on adjacent streets. My question here is probably more about wording (gosh, I hate wordsmithing at the 11th hour - don't you?? lol!). Maybe I'm reading it wrong, but it really seems like it should confirm to the structure of the other statements.
Thanks for any clarity - we can chat tonight too
