(a) Design and improvement standards for intersections are suggested minimums for all street intersections in subdivisions. All such intersections shall be designed and constructed in accordance with the standards specified in Table 2.
(b) Multiple intersections involving junctions of more than two streets shall be avoided.

(b) Local-collector | 200 - all cases |
(c) Collector-collector | 300 - all cases |
(d) Collector, marginal access - arterial | 1320 - all cases |
