I think your tree is Fraxinus angustifolia Vahl - the Narrow-leaved Ash. It's increasingly being planted in urban areas. Its native to southern Europe, N.Africa and W. Asia.
First Latin name I could remember, as the common name's a direct translation: angusti- meaning 'narrow', -folia relating to 'leaf'. It's a favourite, particularly at this time of year, as it turns to copper from the top down.
Fred, what distinguishes that one as Vahl?
That's right. Strictly speaking one should always give an authority, i.e. the name of the creator of the scientific name when using the scientific (latin) name. It's a bit cumbersome but sometimes the same binomial has been dreamt up by different scientists and relate to two (or more) different things. The laws of nomemnclature give priority to the first valid use of a new binomial name and so the later names become invalid...but might still end up being widely (if wrongly) used....therefore it's always safest to give the full name with authority.
