Too high footer on (custom) title page in scrartcl

Question

I wanna have custom title page in my document created with scrartcl class. I'm using titlepage environment (which I believe sets thispagestyle=empty). Still I have rather high footer: just as in normal text (which of course looks ok because it has page numbers in a footer).

What are preffered ways to have the footer on title page smaller? I'm thinking principally of two approaches: 1) footheight might be discarded (i.e. = 0), 2) last portion ot text (city and date) might become part of the footer.

My code is as follows.

\documentclass [fontsize=14pt, paper=a4, pagesize, DIV=calc] {scrartcl}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}

\usepackage{paratype}
\usepackage{setspace}
\onehalfspacing

\parindent=1.25cm
\frenchspacing

\KOMAoptions{DIV=last} % recalculate text area as recommended in KOMA-guide

\begin{document}
  \begin{titlepage}
  %
  %\thispagestyle {empty}
  %
  \begin {center}
    %
    [Federal Authority]
    %
    \vskip 15pt
    %
    My University
    %
    \vskip 15pt
    %
    My Department
    %
    \vskip 15pt
    %
    My chair
  \end {center}
  %
  \vspace* {\fill}
  %
  \begin {center}
    %
    Me
    %
    %
    \vskip 18pt
    %
    Title
    %
  \end {center}
  %
  \vspace {\fill}
  %
  \begin {center}
    %
    City \\
    %
    Date
    %                Here will be huge vertical space for some reason
  \end {center}
  %
  \end{titlepage}

\lipsum

\end{document}

You can load the package scrlayer (part of the KOMA-Script bundle) and define your a special pagestyle for the titlepage.

\usepackage{scrlayer}
\DeclareNewLayer[
  foot,
  foreground,
  contents={%
    \raisebox{\dp\strutbox}[\layerheight][0pt]{%
      \parbox[b]{\layerwidth}{\centering City\par Date}}%
  }
]{titlepage.foot.fg}
\DeclareNewPageStyleByLayers{titlepage}{titlepage.foot.fg} 

and

\begin{titlepage}
\thispagestyle{titlepage}
...
\end{titlepage}

Code (with the additional changes by @egreg):

\documentclass [fontsize=14pt, paper=a4, pagesize, DIV=calc] {scrartcl}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}

\usepackage{showframe} %%% just for the example

\usepackage{paratype}
\usepackage{setspace}
\onehalfspacing

\parindent=1.25cm
\frenchspacing

\KOMAoptions{DIV=last} % recalculate text area as recommended in KOMA-guide

\usepackage{scrlayer}
\DeclareNewLayer[
  foot,
  foreground,
  contents={%
    \raisebox{\dp\strutbox}[\layerheight][0pt]{%
      \parbox[b]{\layerwidth}{\centering City\par Date}}%
  }
]{titlepage.foot.fg}
\DeclareNewPageStyleByLayers{titlepage}{titlepage.foot.fg}

\begin{document}
\begin{titlepage}
\thispagestyle{titlepage}
\centering
[Federal Authority]

\vspace{15pt}

My University

\vspace{15pt}

My Department

\vspace{15pt}

My chair

\vspace{\fill}

Me

\vspace{18pt}

Title

\vspace{\fill}
\end{titlepage}
\end{document}

Note, that the code above needs KOMA-Script Version 3.14 or newer. The current version on CTAN, in TeX Live and MiKTeX is version 3.15 and the up to date major release is 3.16.

Unfortunately Overleaf still uses the old KOMA-Script Version 3.12. (The command \KOMAScriptVersion prints the used version in the document.) So with Overleaf you have to change the code

\usepackage{scrlayer}
\DeclareNewLayer[
  foot,
  foreground,
  contents={%
    \raisebox{\dp\strutbox}[\layerheight][0pt]{%
      \parbox[b]{\layerwidth}{\centering\titlepagefoot}}%
  }
]{titlepage.foot.fg}
\DeclareNewPageStyleByLayers{titlepage}{titlepage.foot.fg}
\newcommand\titlepagefoot{City\par Date}

Answer 2

You can use \enlargethispage. I also changed somewhat your code: better using \vspace than \vskip and just a \centering declaration.

\documentclass [fontsize=14pt, paper=a4, pagesize, DIV=calc] {scrartcl}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}

\usepackage{showframe} %%% just for the example

\usepackage{paratype}
\usepackage{setspace}
\onehalfspacing

\setlength{\parindent}{1.25cm}
\frenchspacing

\KOMAoptions{DIV=last} % recalculate text area as recommended in KOMA-guide

\begin{document}

\begin{titlepage}

\centering
\enlargethispage{3\baselineskip} % <------------ adjust at will
