Officer report

Objections from the public

One objection letter raised concerns about shared routes, crossings, Conway Close access, traffic, privacy, wildlife, pollution and bridleway details.

“One letter of objection has been received and objects on the following grounds • The proposed layout should not have a shared cycling and pedestrian route and therefore does not meet the requirements of the Joint Core Strategy, NPPF, or LTN 1/20 and consideration should be given to creating a separate route for cyclists and pedestrians.”

“The access proposals do not comply with policy S10 of the Joint Core Strategy • The access proposals are not in accordance with the application Design and Access statement. • No proper consultation on the application has been undertaken in relation to the access arrangements • There is a lack of details on the adjacent bridleway. • The bridleway should have a separate provision for cyclists.”

Officer report

Who spoke at the meeting

A resident objected that the missing secondary school and unsafe or excessive travel routes would prevent a sustainable community, while the agent supported the scheme.

What members discussed

Members discussed school provision, playing fields, housing density, affordable housing, road proximity, parking, the Pegasus crossing and flood-risk conditions.

“After the presentation at the meeting the Committee gave consideration to: • The rationale for the loss of a primary school and the secondary school from the original provision of, two primary schools, one secondary school and playing fields. Whether the loss of the secondary school would include the playing fields. Neighbouring Kings Heath playing fields had been lost to provide access for the development.”

“In response to questions from members the Major Projects Officer added: • In respect of the first primary school, the developers had nominated the Local Education Authority to build • For the secondary school, before the occupation of the 300 th dwelling, they need to complete the transfer of land to the Council • The current indication was that a second primary school was not needed due to lack of demand • The secondary school spaces would be provided on site or through…”
