§ 9-4.636 ARTERIAL STREET BUS TURNOUTS; DEVELOPMENTS; NOTICES TO THE TRANSIT DISTRICT.¶
The Director of Public Works shall notify the Transit District whenever the city receives an application for any of the following types of development:
(A) A housing project with 50 or more units which project is adjacent to an arterial street;
(B) A commercial or industrial project which is adjacent to an arterial street; or

§ 9-4.637 ARTERIAL STREET BUS TURNOUTS; REVIEWS BY THE TRANSIT DISTRICT; DETERMINATIONS.¶
The Transit District shall review proposed projects which are referred to it by the city and, within 15 calendar days after the receipt of such referral, notify the city whether a bus turnout and/or a bus shelter shall be required to be constructed in conjunction with the project. Such determination shall be made upon the existence of a bus route on the adjacent street or the likelihood that a route will be created along such street. If the Transit District finds that a bus stop at the subject location is or would be desirable, the Transit District shall notify the Director of Public Works to require the installation of the turnout and/or shelter.

§ 9-4.638 ARTERIAL STREET BUS TURNOUTS; FAILURE OF THE TRANSIT DISTRICT TO RESPOND.¶
If the Transit District fails to respond to the referral within 15 calendar days as specified in § 9-4.637 of this article, the requirement for a bus turnout or shelter may be deemed waived. However, if the Transit District subsequently affirmatively responds, and if there is sufficient time to incorporate the design of the improvements into the developer's application and plans, then the Director of Public Works may require such construction.
('66 Code, § 9-4.638) (Ord. 684-C-S, passed 8-27-87)
§ 9-4.639 ARTERIAL STREET BUS TURNOUTS; REQUIREMENTS FOR CONSTRUCTION.¶
If the Transit District requests the construction of a bus turnout and/or shelter as specified in §§ 9-4.637 or 9-4.638 of this article, the Director of Public Works shall make such construction a condition of approval of the development project. The Director of Public Works, however, may override the determination of a need for a bus turnout and/or shelter. If he does decide not to require construction, he shall state the reasons in writing to the Transit District. A failure of the city to require construction because of error or omission shall not create any liability of the city to the Transit District. When construction of the improvements is required pursuant to this article, they shall be constructed in conformance with specifications approved by the Director of Public Works and/or the Transit District. Bus shelters shall become the property of the Transit District, which shall have the obligation for the maintenance of such shelters.
